Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft – examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period (5th-3rd century BC). Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic “drawing” in thread

A well-known basic cotton or blended fabric it is generally 2/1 or 3/1 warped faced right hand twill. This is very durable most popular all over the world. Now this time all types of fashionable garments are made from denim mainly used in sportswear and evening wear. The fabric specification of denim= (20 x16 Ne)/ (90X60)
A strong, warp-faced, cotton twill fabric of medium to heavy weight generally made with coarse carded yarns in in a two up, one down left- hand twill, in a dense construction. Resembles one denim bat the latter is warp faced, right hand twill. Three up one down twill is also called as drill. The fabric specification of denim=(14 x16 tex)/( 50X32cm), (27x46tex)/ (44x32cm), (38x43tex)/(36x20cm). Used in the greige bleached, or printed state, for a wide variety of such uses as work cloths, pocketing, shoe-linings, uniforms, book bindings, coated fabrics, industrial fabrics.

A tightly woven, warp- faced made with 45 or 63 degree angle twill and given a clear finish. The warp generally employs twice the number of the yarns per inch as thus filling at the diagonal rib or cord is distinct, closely set and raised. Made with carded or combed, single or ply yarns of worsted, cotton, silk, manufactured staple and various combinations in dress and suiting weights. This types of fabrics are mainly used in men’s, women’s, children’s wear, sportswear, suit’s, uniforms riding habits, rain coats, sky wear, fabric shoes.
poplin :
A durable plain weave fabric having fine cross ribs produced by employing work that are finer then the filling yarns, with about two or three times as many end per inch as picks. It is produced from combination of such types of fibers such as silk, cotton, wool. It is mainly used in women’s wear, sportswear, shirt, pajamas, and decorative fabrics. The specification of a poplin fabric = (14/2 x 60 Ne) / (60 x 14).
It is warp-faced fabric. It is also three harness cotton or cotton blend twill fabric. In Jean fabrics generally woven of corded yarns in weights lighter than drill, it has more yarn per inch and finer twill line than drill. Jeans occasionally are made with cotton warp and low-grade wool or Soddy filling. It is used backing of the coated fabrics children’s sportswear, decorative fabrics. The specification of a jeans fabric = (30 x 30 Tex) / (36 x 26 cm).

CAD, Pattern & Marker Department
Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. CAD often involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.
CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) objects.
CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals. The modern ubiquity and power of computers means that even perfume bottles and shampoo dispensers are designed using techniques unheard of by engineers of the 1960s. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.
An ornamental design in a fabric Pattern may be produced either by the construction of the fabric by applying designs, by other means for printing, embossing or embroidery.

It is a thin paper which contains all the necessary pattern pieces for all sizes for a particular style of garments. It gives special instructions for cutting. It can be done both manually and computerized method.
In computerized method all information’s are stored in the pre-fashioned data file and an operator helps the computer to make the best choice.
Maker width is taken according to the fabric width. Fabric spreading should be done by taking the guideline from maker width
Points should be considered before maker making:
• Fabric width must be higher than maker width (1/2”).
• Fabric length must be higher than maker length (1”+1”).
• When pattern pieces are laid down on the layer of fabric, the grain line should be parallel to the line of the warp in a woven fabric and Wales in knit fabric where pattern pieces are laid across the layers, the line is kept parallel to weft / course.
• All the pattern pieces of a garment should be alone the same direction when laid down on an asymmetric fabric.
• Length of cutting table should be considered.
• Plan for garments production should also be considered.
• For the efficient marker, it is required to ensure the following things:
• One should be easily see the full length.
• To know about the appropriate width.
• The marker starts with the large pattern pieces. Then fits the smaller pieces in the gap of the larger pieces. Thus the fabric wastage is minimized and efficiency is increased.
• After that the patterns are shuffled in various directions to reduce the marker length. It also helps to increase maker efficiency.

Cutting Section
Fabric cutting:
The definition of fabric is very complex. In garments industries fabric is cut from lay and spreading accuracy and properly which is termed as fabric cutting.

Production pattern

Requirements of fabric cutting:
• in cutting
• Precession of cut
• Clean edge
• Infused edge
• Consistency
• Support of the lay
Lay Preparation:
• Layers shall collect lay slip, cutting job card, lay sheet from the minusing person.
• Layers shall lay the fabric according to the lay slip details.
• Layers shall collect rolls of only one shade and one width for the lay at a time ,if any shade change is noticed then use separators- i.e. lay sheet has to be placed for identification.
• The cutting in charge has to decide upon the kind of lay such as – face-to-face, face to back, face up, face down, grain line, nap direction during the PP meeting stage upon the analysis of the garment.
• Use lay separator sheets to separate rolls of different shades if used in the same lay—the shade category should be mentioned on every lay separator sheet also.
Lay Precaution:
• During lying the layers should check the lay-to-lay shade variation & also center to selvedge variation as a part of online check procedure.
• QC shall inspect the lay for lay tension, width, length, grain line, nap direction etc.
• End wastage for lying of fabric shouldn’t be more than 1 cm.

Bulk Cutting:
• Lay wise manpower requirement must be planned.
• Cutters must be trained on the methods of accurate cutting, especially for parts with deep curves. If possible diagrammatic representation of the direction of movement of the cutter needs to be illustrated.
• Cutters shall inspect the cutting machine for oil leakage, straightness of the blade, sharpening quality, evenness in sharpening of the blade, dust accumulation before cutting.
• Cutters shall cut lay as per the mark up using straight knife m/c and move the parts to band knife as per the discussion in PP meeting.
• QC shall inspect all the cut parts using patterns and initiate corrective action upon the detection of defect.
• Prepare 1st cut bundle inspection report; notify fabric defects and cutting defects to FM/PM.
• QC should have a cutting checklist against which 1st bundle audit has to be conducted. Checklist should have details of allowances, tolerance included in pattern, notches and embellishments placement markings details.
• The size of the straight knife for cutting lightweight fabrics should be 6” only.
• Straight knife must be uniformly sharpened from top to bottom as frequently required,. This ensures even sharpening along the full length of the knife/blade.
Note: If sharpening of blade is uneven / inconsistent, it would result in uneven depth of notch marks and variation in cutting too…
• For Band knife cutting, patterns preferably made of tin should be used.
• The patterns used for band knife must be changed regularly upon monitoring the w wear and tear on the pattern, due to frequent usage.
Method of fabric cutting:
There are three method of cutting are follow
• Manual
• Hand operated scissor.
• Manually operated power knife
• Straight knife
• Band knife
• Round knife
• Die knife
• Notcher
• Drill
• Computerized
• Knife
• Laser
• water knife
• Plasma torch

Straight knife cutting machines are used in Opex & Sinha Textile Group. Because it has some advantages from others which are follows.
• Comparatively cheap
• Can be transferred easily
• Easily operated
• Round corner can cut smooth easily
• Fabric can be cut from any angle
• Directly garments components separated from fabric lays

Calculation for cutting man:
Fabric consumption calculation system:
The quantity of fabric which is required to produce a garment is called consumption. We can calculate and determine the consumption of fabric by the following two system:
i. Marker planning system
ii. Mathematical system

Marker Planning System:
In the system mentioned here studying the range of size, following six pcs of six sizes can be sorted out from size range. As in XS, S, M, L, XL, XXL Besides these we can choose three pcs of three size or twelve pcs of twelve sizes for our convenience. It depends on our intelligence and the size range; thereafter paper pattern can be made by grading to the above garments as per measurement sheet. Having made the paper pattern it should have to lay each parts of the paper pattern on a marker paper of similar fabric width. After marking the paper pattern if we measure marker paper to length wise, we will find an aggregate consumption of six pcs of garment. If the aggregate is divided by six, we will find a consumption of one pc garment as such we will find a consumption of one dozen garments from the above system calculations.

Mathematical system:
Whatever is the fabric consumption of a garment or whatever quantity of fabric is required to produce a garment is measured by mathematical system। Mathematical system is a system of rough estimation. Consumption of a sample garment or consumption as per measurement sheet is calculated mathematically by measuring the area of length and width of each parts of each pcs of garment

Fabric Consumption Calculation of a Basic Pant:
Fabric width =60’’ -1’’
½ waist circular =46cm +8(seam allowance) =54cm
Front rise =28cm including WB +8(seam allowance) =36cm
½ thigh circular =36cm+6(seam allowance) = 42cm
Inseam length =82cm +3(seam allowance) =85cm
# Consumption formula = ( ½ waist cir x front rise) x2 + ( ½ thigh cir x inseam length) x 4÷ 36 ÷ 59 + waste %
= [{( 54x 36)x2}+{(42×85)x4}÷36÷59+5%] cm
= [( 3888+14280) ÷ 6.45÷36÷59+0.05] yds/piece
= (1.326+0.05) yds/piece
= 1.72 yds/piece
= 1.78 yds/piece

Embroidery Designs Section

Embroidery is an ancient variety of decorative needlework in which designs and pictures are created by stitching strands of some material on to a layer of another material. Most embroidery uses thread or wool stitched onto a woven fabric.
Embroidery has traditionally been used to decorate clothing and household furnishings including table linens, tray cloths, towels and bedding, but you can literally embroider anything as long as it is made out of an evenly woven fabric and can be held firmly in the hand or in a special embroidery hoop or tapestry frame. The art of hand embroidery is a painstaking and laborious process, but today garments are often decorated with machine embroidery instead.
Embroidery has also been used as a form of art and for decoration, through the creation of embroidered or cross-stitch samplers, tapestries, wall-hangings and other works of textile art. Annemieke Mein is one example of a contemporary textile artist who creates embroidered work.

Sand blasting and other dry process
Sand blasting is a mechanical process of faded affect formation on garments fade form heavy fabrics like denim and jeans, this process is followed by a wash of dying process. Aluminum oxide is used for sand blasting. These aluminum oxides are blown at very high pressure through a gun, the gun has a switch to start and stop flow of aluminum oxides. Garments to be sand blasted are placed on the bed of closed chamber. Then the gun is operated by hand, when the switch of the gun is operated, aluminum oxides from a feeding chamber through pipe and gun starts blowing. the blowing of aluminum oxides are done on the garments surface , the area of the garments fabric surface is instantly faded by the flowing action of aluminum oxide due to frictional effect of aluminum oxide the blow of the aluminum oxides on the garment fabric surface is controlled at 10 degree to 20 degree angle. Higher the blowing angle, higher the fading affect and higher the risk of garments fabric damage.

Final Inspection
Garments are inspected by AQL. In this system samples are collected inspected by statistically from the lot size and will decide the lot of garments to be granted or rejected. AQL is mainly used in final inspection after garment making.
Acceptable quality level (AQL) sample inspection methods have been proven to be accurate over a long run. However, the quality level of merchandise at destination is sometimes lower than the per-shipment inspection results. This may be due to transport, handling, change in environment and/or reliability problems. Buyers are therefore advised to take this into consideration when deciding the AQL levels.
Defect Classification: The client defines the AQL and the maximum number of defective goods allowed in the sample size. Defects detected during visual inspection are usually classified within 3 categories: “Critical”, “Major” and “Minor”
Critical: likely to result in unsafe condition or contravene mandatory regulation or reject by import customs.
Major: reduces the usability/function and/or sale of the product or is an obvious appearance defect.
Minor: doesn’t reduce the usability/function of the product, but is a defect beyond the defined quality standard more or less reduces the sale of the products.
An Individual with defect(s) is called defective sample. In the inspection process, one defective sample is counted one for the most serious defect only no matter how many defects found in the said sample.
Clients can specify what points are minor, major or critical in a defect classification checking-list together with the inspection criteria and product specification.


In this industrialized age, environmental pollution is a matter of great concern. Surface water pollution is one of the elements of environmental pollution. Chemical processing industries especially textile processing industries are claimed to produce huge effluent to discharge in our rivers. A complex mixture of hazardous chemicals both organic and inorganic is discharged into the water bodies from all these industries, usually without treatment.
It is well known that textile mills consume large volume of water for various processes such as sizing, desizing, scouring, bleaching, mercerizing, dyeing, printing, finishing and washing. Due to the nature of various chemical processing of textiles, large volumes of wastewater with numerous pollutants are discharged every day. In Bangladesh most of the industrial units are located along the banks of the rivers and they do not use Effluent Treatment Plant (ETP) for wastewater. As a consequence, industrial units drain effluent directly into the rivers without consideration of the environment.
Setup an effluent treatment plant is mandatory for a factory today. Authority gives no permission of electricity and gas connection to a new factory without ETP.

The raw waste water (Raw Effluent) from the process of the plant would be first screened through a manual bar screen strainer channel, where all particles with dia. > 5mm as well as small pieces of the fiber and floating suspended matters like polythene paper, polythene bags, rags and others materials removed by bar screen net. The bar screen consists of parallel rods or bars and is also called a bar rack. These devices are used to protect downstream equipment such as pumps, lines, valves etc. from damage and clogging by rags and other large objects. The bar screen is cleaned manually by means of rakes. The screening is disposed of suitably after they are de-watering. The screened clean effluent flows by gravity to an equalization tank.

Equalization and Skimming:

The raw waste water from the screen chamber is collected in the equalization tank, where it is equalized with respect to its characteristics and homogenous flow and an uniform pollution load as well as to make bacteria acclimatized the waste water is stored in a tank. High speed bottom fixed aerating device which blows air through the waste at a rate about 0.1 CUF of air per gallon of effluent. The rising air tends to coagulate the grease and oils and cause them to rise to the surface where they can be removed by a scraper mechanism. Besides, in order to accomplish a proper equalization of both varying loading and flocculating pH values. The equalization tank is designed for hydraulic retention time of around 6 hours. A substantial part of the COD will also be removed by the dissolved air flotation process.


Coagulation & Flocculation:

The homogenized effluent is than pumped to a flash mixing tank followed by a flocculation tank. Where added coagulants like lime (Calcium Hydroxide) and Ferrous Sulfate (FeSO4) for coagulation of the total dye particles. The basic idea of adding coagulant is to bring together all the suspended and dye particles so that they can precipitate out in a flash mixing and coagulation mechanism. Adequate quantity of poly electrolyte polymer solution are dosed to enhance the process of color removal by the flocculation process.

Precipitation and Sedimentations Tube Settler-1:

The flocculated effluent is taken by natural gravity in to the tube settler-1 from flocculation tank for precipitation of dyes and suspended particles. The flocs formed are removed in the downstream tube settler-1 by the help of tube settler media. The effluent will further flow by overflow system to a pH correction tank where requisite quantity of acid will be dosed and pH will be adjusted as per the requirement.


pH Correction:

The overflow effluent from tube settler-1 tank is than taken by gravity in to the pH correction channel for neutralization. 33% HCl acid is dosed for neutralizing the pH from around 10 to 7. The pH correction channel is designed for hydraulic retention time of around 10 minutes and is provided with slow speed agitator for thoroughly mixing of waste with acid. A pH indicator is installed in the tank for measuring the pH (optional).


Biological Reactor 1 & 2:

The neutralized effluent is taken by gravity in to the biological treatment aeration tank for treatment of organic matter to reduce BOD/COD aerobically. The biological reactor is designed on extended aeration principle. The aeration is provided with fixed type surface aerator for providing the required oxygen for the biological degradation of BOD and COD. The air is supplied by means of the bubble diffusion.

Tube Sattler- 2:

After aerobically treatment effluent flows by gravity to the tube settler – 2, the biological solids generated are removed from the tube settler – 2 by the help of tube settler media.

Filter Feed Pump:

The effluent from tube settler – 2 overflow in to the pressure sand filter and activated carbon filter feed pump. From here the disinfected effluent is pumped by means of the pressure sand filter feed pump to the pressure sand filter. The pump is normally operated in automatically with interlock to the level switch in the filter pump.

Pressure Sand Filter:

The effluent is pumped to the pressure sand filter. The filtration takes place in the downward mode. The filter is filled with a layer of graded sand media supported by a layer of graded gravel. The suspended matter in the effluent is filtered out in this unit, the effluent is then flown into the activated carbon filter.

Activated Carbon Filter:

The filtered effluent from the pressure sand filter flows into the activated carbon filter. In this unit to the feed flow is downward through a layer of granular activated carbon filter in which dissolved organics in the effluent are absorbed.

Treated Effluent Tank:

The effluent emanating from the activated carbon filter is collected in the treated tank. From this sump the final treated effluent is disposed off. As indicated before, this effluent is utilized for backwashing the pressure sand filter and activated carbon filter units.

Sludge Treatment:

The sludge generated in tube settler-1, tube settler-2 and biological reactor is taken to a sludge sump and pumped to a sludge thickener where sludge is concentrated. The thickened sludge from the thickener shall be pumped to sludge drying bed for de-watering. The de-watered sludge is formed into cake by natural dry or a centrifuge. The dried cake will be disposed in a tank. The overflow from the sludge thickener will be flow back to equalization tank for further treatment.

All work study- techniques are classified into two main groups the specimen bellows by typical:



Method Study

May be defined as:

The systematic recording and critical examination of existing and alternative methods of work to facilitate the introduction of more efficient and cost effective methods

The basic procedure:

Select: identifies the areas where results can be achieved these are usually where there are:

Bottlenecks        increased cost                   persistent overtime working,

Excess fatigue   safety hazards                   high labor turnover         high absenteeism


Record: Record though observation all of the exact details of an operation with regard to:

Machinery used               attachments used           operator method             quality specification

Handling system               work place layout            sequence                            position online

Examine: critically examine all of the recorded method details. Question each detail:

Can it be eliminated?                                                 Can it be combined?

Can the sequence be changed?                                Can it be simplified?

Easy motions characteristics

The methods analyst should strive to incorporate the following into methods:

Minimum:          Using finger, wrist, and elbow movements rather than making shoulder and body movements.

Simultaneous:    Using both hands at same time whenever possible.

Symmetrical:     Left and right arms moving at the same time in opposite directions.

Natural:               Free sewing movements are faster and easier then controlled movements.

Continues:          Continuous curve movements are better than straight line movements involving sudden or Sharpe changes in directions.

Rhythmic:            Smooth automatic movements must be encouraged.

Habitual: `          Movements that have become automatic as they do not require additional


Workplace layout:

The layout of a workplace impacts directly on the pattern of movements and consequently time taking to perfume and operation

When analyzing a method the following steps should be considered:

Step 1:

Sketch the existing workplace layout.

Sketch the shape of the work table noting any modification to the standard, e.g. extensions or cut downs

Sketch the position and clearly identify any work aids or attachments e.g. guides, reel feed etc.

Sketch in the position of products parts before they are processed; clearly identify the part of parts

Sketch where the parts are placed after processing

Step 2: analyze how to products parts are moved within the work place.

How part is first obtained                             how the operators holds the part

Where the part is move to                           how the part is presented to the machine

How the part is disposed of by the operator        where the part is disposed to.

Step 3:

Describe the method in simple movements; GSD is the best analysis tool for this.

The motions are typically:

Pick up




Cut/ trim & Place aside


Step 4:

From the list of movements the key points for attention should be identified

Finger/ hand position

Number of sewing bursts

Quality specification- tolerances, notch alignment, fabric position etc.

Special skill requirements


Step 5:

The critical examination stage:

Identify and eliminate excess movements’ e.g. checking, smoothing and positioning motions that are not fundamental to the method or company policy.

Identify and eliminate stretching or body movements.

Strive to achieve a method that contains only motions with “Easy Characteristics”


Work measurement:

There are number of different techniques that can be used to carry out work measurement within the sewn products industries, the traditional alternative to general sewing data is time study.

The skills required are:

  1. The ability, skill and experienced to read and operate a stopwatch.
  2. The ability, skills and experienced to assess the rate of working (performance) of individuals workers.


Time study:


This is the process by which we calculate the SMV (standard minute value) in “in process inspection”. There are two types of SMV such as estimate SMV and garments SMV. It is done by following formula,

Take a stop watch and take times for 10 times for a operation and finally calculate the SMV of this operation and production per hour.


Steps in taking time study:

A glossary of terms is contained in the manual so that the student may refer to it for specific definitions.

  1. Prior to commencement it is essential that there are commutations to all interested parties.

Manager’s       supervisor’s     workers representative’s       operators

  1. Ensure the prevailing conditions are suitable for a reliable time study.
  • The operators are properly trained and skilled – not trainees
  • The materials being used are of the correct quality.
  • There is sufficient work available for a time study to be completed without interruption.
  • The machine, equipment and work aids are correct and in working order
  • Ensure that health and safety rules are observed
  • The work place and working method meets the official special specifications.


  1. It is vital that all relevant details are recorded before the start of study e.g.

Study number  date     name of work study Eng.        Date of study   product type

Style reference           size      color    fabric type       trim details     quality specifications

Department    line/team/section machine type machine speed stitch density Attachments work aids.

  1. Before commencing the study break the operations down into elements so that observed assessment of rate of working and time taken can be recorded during the study.

After completing the study:

  1. Record the watch elapsed time and calculate the observe study time . Then calculate unaccounted time and watch error. The tolerance allowed – ± 2%
  2. Extend the observe elemental /operation rating  and times into basic time
  3. Calculate the average basic time for each element /operation cycle.
  4. Apply the appropriate relaxation, Delay and contingency allowances to the basic times in order to calculate the standard time either for each element or the operation as a hole.
  5. Where an appropriate some all of the elemental standard times in order to compile a standard time for the operation.
  6. As appropriate convert the standard time to the standard time allowed time by applying the appropriate performance factor to the standard time using the formula below.



Line balancing:

Line balancing is the allocation of sewing machine according to style and design of garment. It depends of that what type of garment we have to produce.


The Objectives of Line Balancing:

Line balancing is a main part of a mass production. These kinds of systems, regardless of being different in details, are workstations in a sequence. Row material is included in the line at the beginning or in the middle. Parts included in the system transfers from one workstation through the other and at the end leaves the system as a completed product. Transfer lines uses manpower very little when compared to assembly lines. The certain properties of Transfer lines are transfer and process of a product automatically through a line.



Objectives that should be gained balancing an assembly line are as follows;

  • Regular material flow
  • Maximum usage of man power and machine capacity
  • Minimum process times
  • Minimizing workstations
  • Maximum outputs at the desired timed
  • Reduce production costs

Importance of Line Balancing:

The importance of line balancing could be summarized as follows –

Good line balancing increases the rate of production;

This is the pre-condition for smooth production;

Line balancing helps to compare the required machinery with the existing one and make a balance;

It also helps in the determination of labor requirement;

Good balancing reduces production time;

Profit of a factory can be ensured by proper line balancing;

Proper line balancing ensures optimum production at the agreed quality;

It reduces faults in the finished products;

Line balancing helps to know about new machines required for new styles;

It becomes easier to distribute particular job to each operator;

It becomes possible to deliver goods at right time at the agreed quality for least costs.

Steps in Line Balancing:

Now-a-days, Standard Minute Value (SMV) is used as a tool for the line balancing, production control and the estimation of efficiency. In a similar way, the time taken to do a job for making garments like shirt/trouser/blouse/dresses could depend upon a number of factors like –

  • The length of the shirt/trouser/blouse/dress;
  • The number of stitches per inch;
  • The presentation of item;
  • The pricing of garments.

Planning Department:

When the factory gates a new order planning department needs to follow up some very important points those are given below

1. Before start sewing , select sewing line and fixed target to sit with IE & Production AGM.

2. Before start production ensure size set measurement repot.

3. After correction pattern given 1st line before ¾ days to give the other line.

4. Given schedule to all department like Sewing, Cutting, Washing & Finishing section.

5. Before start sewing ensure fabric and trim in-house status.

6. After start 1st line, ensure initial inspection within 3 days & before bulk cutting should not give others line.

7. Ensure to give production sample before 1 week to 1st shipment.

8. Ensure denim & over dye process garments production 5-7 days before from the shipment date.

There are some other aspects which Planning Department ensures. Makes a whole month’s shipment plane regularly follow-ups the everyday production rate and works on how to improve the production. They also make a plan about approximate production days needed for the individual style’s production & and make sure full production is complete in estimated time. Which style goes in which line, thoroughly check and quarry about the individual line’s production for the in time shipment, makes a whole planning about fabric in-house to sewing production line then wash to shipment.




Garment merchandising

Merchandising is one of the most important parts for garments trade. Without merchandising this trade never be fulfill. Merchandiser deals or handles all the things from buyer to production. He is the center for all the tasks. After getting an order, merchandiser calculate all the things, what he need to complete this order & make a nice plan by which he can do the shipment in time with buyer’s requirement. In factory level, merchandiser makes all the orders for accessories needs for an order like; fabric need, sewing thread, button, washing if necessary, carton, polybag, shipment arrangement etc. Actually merchandiser make looks on the whole progress. Normally, the production people are always try to do work in delay, thus many trouble can come for the shipment. But, merchandiser always makes a good follow-up to work in time with right quantity & right quality. In the other hand, merchandiser deals with the buyer’s about order approval & comments.

At last, we can say that, merchandising is the heart of garments trade. Without this garments trade is valueless.

Definition of merchandising:

The “Merchandizing” is known to the persons specially involved in garments trade. The term merchandising has been derived from the merchandise. Merchandise means goods that are brought & sold.

The term Merchandizing may be defined as: Person who merchandising the goods, specifically for exports purposes. Garments merchandising means buying raw materials & accessories, producing garments, maintaining required quality level and exporting the garments within schedule time. From the above definitions, we can say that a person involved in garments merchandising needs a wide range of knowledge & skill to perform his job successfully. The job itself is technical and general as well.

Merchandiser is data bus between buyer & seller:

Merchandiser is he or she, who builds up a relationship with the buyer and acts as a seller. He plays a vital role in an organization in a sense that he bears more responsibility than other in regards to execution of an order. The responsibility which he bears on the job is as follows:

  • He represents as a buyer to a factory.
  • He represents as a seller to the buyers.
  • he inspects quality as a buyer(from the buyer’s point of view)
  • He or she negotiates a price for the sellers
  • He looks at deal from sellers point of view
  • He looks into the business to flourish more in the future
  • He or she tries to offer the deal more competitive without compromising the quality
  • His or her object is to satisfy the buyers to progress more of the future business
  • His or her aim is to impress the buyer by means of:
  • Right products, quantities & qualities.
  • Right time & Honesty.

Function of a merchandiser:

When an export order is placed to a merchandiser, He or she has to schedule the following main functions to execute the order perfectly on time:

  • Fabric requirement calculations
  • Accessories requirement calculation (e.g. thread, button, label, polybag, carton etc.)
  • Sourcing of yarn & fabrics & accessories.
  • Possible date of arrival of fabrics & accessories in the garments factory
  • Costing
  • Garments production planning with the help of production DGM.
  • Pre –shipment inspection schedule
  • Shipping documents.

All the main functions, mentioned above are important but the procurement of the fabric & accessories are most important as there are many technical parameters involved in specification in this area. In most collection of fabric for the garments is to collect in time is a major problem. To procure a fabric we should clearly specify the technical specimen of the fabric during placing a fabric supply order, the following list of points should be considered in preparation of the contract before placing a fabric purchase order.

Types of Merchandiser:

1. Junior Merchandiser

2. Senior Merchandiser

Activities of a senior merchandiser in a factory:

  • Sample development
  • Price negotiation
  • Order confirmation
  • L/C opening
  • Opening summery
  • Sourcing
  • Material collection
  • Production planning
  • Production monitoring
  • Quality assurance
  • Arrange final inspection
  • Arrange shipment
  • Main task is ”production monitoring”
  • Collect “inventory report” from store
  • Swatch making ,sample making & getting approval from buyer
  • Arrange preproduction meeting  in order to prepare a schedule for smooth production
  • Place order to different production unit
  • Collect ”Daily Production Report &Daily Quality Report”
  • If any shortage in store, arrange locally.
  • Arrange final inspection

Activities of Junior Merchandiser in a factory:


Export order collect

Send to the Buyer

If Ok, Then making the different types of sample according to the buyer requirement


Negotiation with Buyer

Get Approval

Preproduction meeting

In house accessories & fabrics

Line balancing

Production continuing (follow up)

Process flow chart of a merchandiser:


Qualities of a merchandiser:

  • Good knowledge about fiber, yarn, fabric, dyeing, printing, finishing, dyes, color fastness, garments production, etc.
  • Clear conception of the usual potential quality problems in the garments manufacturing.
  • Good knowledge of the usual raw materials inspection systems & garments inspection system
  • Knowledge of the quota system used in each of the production countries, duty rates, custom regulation, shipping and banking documentation etc.
  • Right consumption knowledge of various goods
  • Costing knowledge of raw materials
  • Order getting ability
  • Sincere& responsible
  • Hard worker

Negotiation with buyers:

The most critical work is the procurement of garment export order. Normally garment export order is found from the potential garment importers called garment buyer. Anybody wants to collect garments export order, should be able to convince the buyer. When the buyer is convinced about garment production, garments quality, garments costing and shipment ability of a garments exporter, he or she can think about issuing garments export order.

Without clear confidence among buyer& exporter from both sides, may be a risky business deal. If a garment exporter can continuously deal with only three or four buyer with buyer’s satisfaction, it will be sufficient enough to run garment production & garment export business smoothly round the year.

A successful negotiation outcome does not generally occur through luck, but by following a clear process. The process reflects the different levels of knowledge of the subject of negotiation, various parties and the way they communicate at various stages in the negotiation. The following is an outline of steps essential to effective negotiation:

Letter of credit (L/C)

Business transactions usually begin with a purchase order placed by a buyer with a seller. It is very easy to understand, the order, or fax received from the buyer, is not something very reliable and secure. Although the order should be treated as an agreement binding both parties, the buyer and the seller, it is not a guarantee or an instruction for the seller to use to obtain payment for the merchandise shipped. For this reason, the “L/C” comes into the picture.

Letters of credit (L/C) is in general a conditional document extended by the bank in connection with presentation of exp[ort value. L/C pays a very dominant role in this matter. On receipt of this document from the buyer, the exporters become sure that they would obtain foreign currency after the peaceful shipment of the consignment directed by the buyer in the L/C. and for monetary transactions in this connection the negotiation banks stand as a symbol of surety for the exporters. Negotiating bank act on behalf of the exporter and is held liable or responsible for realization of exporter’s money from the L/C opening bank.

A credit may be advised to a beneficiary through another bank (the advising bank) without engagement on the part of the advising bank, but that bank shall take reasonable care to check the apparent authenticity of the credit which it advises.

All credit will always clearly indicate whether they are available by sight payment, by differed payment, by acceptance or bye negotiation. Moreover every credit must nominate the bank (nominated bank) which is authorized to pay (paying bank) or to accept drafts (accepting bank) or to negotiate (negotiating bank), unless the credit allows negotiation by any bank (negotiating bank). The nominated bank unless is the issuing bank or the confirming bank, its nomination by the issuing bank does not constitute any undertaking by the nominated bank to pay, accept or negotiation.

When an L/C issuing bank instructs a bank (advising bank) by any telegrams mission to advise a credit or a amendment to a credit, and intends the mail confirmation to be the operative credit instrument, for the operative amendment, the Tele-Transmission must state “full details to follow” (or words of similar effect) or that the mail confirmation will be the in that case, operative credit instrument or the operative amendment. The issuing bank must forward the operative credit instrument or the operative amendment to such advising bank without delay.

In spite of production of all related documents with the banks, the exporters however, became victims to some unpleasant situations which push them towards the uncertainty of realization of money. This results from the absurdity or ambiguity of L/C. An in most cases from faulty presentation of documents to be required in exports connection. So unless exporters have a clear conception and apprehension about exports business and be aware beforehand about all these documents, they would certainly face some major troubles, in per exports and post

Exports process, Exporters will after all have first-hand knowledge about L/C. they must be in the climax of knowledge. It is L/C  which act a medium of money during the time of execution of exports order and this give  secretly  the exporters that their dues would be obtained in due time.

In fact, in the whole exporter and import process four sides are connected. /in absence of any one of them the process cannot take full shape. These four sides are, exporter, importer, exporter’s bank and importers bank principally. The success of import and export business lies in the exchange of proper and accurate correspondence, any fault in these may cause in total disaster in whole importers and export business. So in order to avoid the ambiguous, absurd and understandable correspondence, both the sides are to exercise special and particular attention. They should remember that the success of export and import business depends mainly upon the careful execution of these things.

In export business, the first thing to do is to make sale contract with the buyer. And this may be made in the presence of both of the importers and exporter. In most cases this may not   be done formally. Yet, it plays a very significant role in the preliminary stage of export business. If this is not done formally, then exchange of letters, fax and email between them from time to time is taken for granted as the contract of the business. This may be styled as verbal contract. This also leaves importance in the business. These exchange documents are important for this reason that many a time this are required by negotiating bank of the exporters. Any loss of these may bring in fault in the business.

In case o9f verbal contact, verbal contract here refers to the contract which is formed through correspondences, exporters are to send pro-forma invoice along with all other details, including specification of goods, definite price and the date of shipment and payment terms. In addition this all other condition, if the exporters think necessary, may be placed in the form.

There are some methods of payment of export value. These are as follows:

1. through letters of credit

2. through advance T.T remittances

3. Deferred payment

4. C.A.D basis etc.

Of all the methods referred to above, letter of credit method is most popular and it is in fashion.

Letters of credit may be of different kind and nature:

1. Revocable L/C

2. Irrevocable L/C

3. Confirmed letter of credit

4. Confirmed and irrevocable letter of credit

5. Transferable or divisible letter of credit

6. Back to back letter of credit

7. Red clause letter of credit

8. Sight letter of credit

9. Unseen letter of credit

10. Revolving letter of credit

11. Stand by letter of credit

All letter of credit therefore, should clearly indicate whether they are revocable or irrevocable. In the absence of such indication the credit shall be deemed to be revocable.

A revocable L/C:

May be amended or canceled by the issuing bank any moment and without prior to the beneficiary.

In case of revocable credit, however, the L/C issuing bank is bound to:

a)      Reimburse a branch or bank with which a revocable credit has been made available for deferred payment, if such branch or bank has prior to receipt by it for notice of amendment or cancellation, taken up documents which  appear on their face to be accordance with the terms and conditions of the credit.

b)       Reimburse a branch of bank with which a revocable credit has been made available for sight payment, acceptance or negotiation, for any payment, acceptance or negotiation, for any payment,  acceptance or negotiation

Made but such branch or bank prior to receipt by it for notice of amendment or cancellation, against documents which appear  on their face to be accordance with the terms and conditions of the credit.

An Irrevocable L/C:

Constitutes a definite undertaking of the issuing bank, provided that the stipulated documents are presented, the term and conditions of the credit are complied with:

The full name of “L/C” i.e. irrevocable letter of credit which means once it is issued by the bank for the buyer and accepted by the beneficiary (the seller) , it cannot be cancelled or withdrawn by the buyer or the opening bank, unless with the consent of the beneficiary. In short, once the buyer opens the L/C form his bank to cover the goods he has purchased, he will have to pay for the goods when the seller ships the goods exactly as per as the terms stipulated in the L/C. Therefore, as far as the seller is concerned, the sooner he has the L/c on hand, the safer he is.

L/Cs can be opened in many ways, but in essence, it is a promise the buyer’s bank makes to the supplier, to pay home when he does certain things with evidence to prove. The things the LC opening bank wants the supplier to do are called “terms”. Therefore, when the supplier receives an L/C, he must read the term carefully to make sure he is capable of fulfilling them all exactly as they are written. If some terms are beyond his capable of fulfilling them all exactly as they are written if some terms are  beyond his ability to fulfill, he must point them out to the buyer and explain why he cannot comply with those terms, and request the buyer  to amend them by means  of an official amendment through the bank.

1)      Confirmed letter of credit:

This is such a credit for which exporter’s bank gives all Shorts of surety for the advance of payment.

2)      Confirmed and irrevocable letter of credit:

Which combines the quality of clause (2)and(3)

3)      Transferable or divisible L/C:

A Transferable credit is a under which the beneficiary has the right to request the bank called upon to effect payment or acceptance or any bank entitled to effect negotiation to make the credit available in whole or in part  to one or more other parties(second beneficiary)

A credit can be transferred only if it is expressed designed as “transferable” by the issuing bank. Terms such as “divisible”, “fractional” assignable” and “transmissible” and nothing to the meeting of term” transferable” and shall not be used, in that case the bank requested to effect the transfer (transferring bank), whether it has confirmed the credit or not shall be under no obligation to effect such transfer expect to the extent and in the manner expressly consented to by such bank. Bank charges in respect of transfers are payable by the first beneficiary unless, otherwise specified.

A transferable L/C can be transferred once only. The credit can be transferred only one the terms and conditions specified in the original credit, with the exception of the amount of the credit.

Back to back L/C:

This type of L/C is opened against the original master L/C.

Red Clause L/C:

In this credit, the export’s bank is directly to advance his dues even before they produce all export documents to the bank. And some clause is attached there. The manufacture must have maintained this clause.

Sight L/C:

It means when the shipper ships the goods covered by the L/C, and presents the document to the bank for negotiation, the bank (the negotiation bank) will credit the proceeds to the shippers account immediately after checking and finding the documents in order. When the documents are sent by the negotiation bank to the L/C opening bank, the L/C opening bank will effect payment to the negotiation bank immediately. such L/C usually say”AT SIGHT” which means “pay when the bank sees the documents”.

Unseen L/C:

It means L/C with time allowed for the opening bank to make payment of a foreign bill of exchange. Or, put in another way, payment from the L/C opening bank to the negotiation bank will only be made after a period of time as stipulated in the L/C. The length can be worked out between the buyer and the supplier, sometimes 60 days, sometimes 90 days or 120 days.

Revolving L/C:

It means that the beneficiary can draw money from such L/C up to the amount specified by means of documents, and after drawing , the amount drawn will automatically be replenished and is available for anther drawing another drawing and so on. 


Costing of garment is a very necessary and important task. In this factory costing is carried out by the merchandising dept. Firstly, merchandiser contacts with the buyer and collects order. Then he is provided a sample from sample section according to the buyer’s specification. The sample section also supplies the fabric consumption. Cost of the fabric is determined according to this consumption. Then he makes the costing of other raw materials, accessories, trimmings etc. He adds then all the production cost, transport cost, commission (buying house, C & F agent) and profit.

A bill of lading (sometimes referred to as a BOL, B/L) is a document issued by a carrier to a shipper, acknowledging that specified goods have been received on board as cargo for conveyance to a named place for delivery to the consignee who is usually identified. A through bill of lading involves the use of at least two different modes of transport from road, rail, air, and sea.

Their goal is to continuously improve their Human resource policies and procedures through education, training, communication and employees involvement. Right from inception the policy of the company has been to provide total customer satisfaction by offering quality garment in time. Working on new concepts in styling & content of the garment is a continuous activity in Opex & Sinha Textile Group with an objective to up the quality and the value of merchandise.

The goal of Opex & Sinha Textile Group is to get high production & to maintain the quality of the product at a minimum cost. The Opex & Sinha Textile Group is notable to produce all types of garment. I think their accuracy will increase to a maximum level. For sewing them is using modern m/c I think their product quality will be higher. For cutting they are using manual straight knife cutting m/c but if they use computerized cutting m/c their accuracy will increase & their efficiency will increase to a maximum level. I think if they improve the above things I think their product quality, their efficiency & their accuracy will be maximum.


Now-a-days Textile field becomes very competitive & the buyer wants 100% quality product. For this reason it is very important to know about the latest technologies in textile sector. To produce a quality product, as a textile engineer I must have a vast knowledge about the

production parameters & how to produce a high quality product. To accommodate the theoretical study with technical and practical things industrial training (Internee) is very important. In my training period I have observed that Crystal Composite Ltd. produce high quality fabric and fulfill the special requirements from the different types of buyers by following different internationally recommended standard method. In my training period I have learned many things such as different types of machines and their functions, techniques of productions and the management system. In this training period I have also learned how the desired product is made ready for shipment from the starting to the end i.e. from merchandising to the packaging. In this training period I have got an idea about the responsibility of different departments of the factory. So I think this industrial training will help me in future.
