A. DEWATERING MACHINE: (M/C Specification)


Brand Name: Santex Ag                                                 Year of Manufacture: 1998


Company: Santex Ag                                                      Type: Santastretch Plus-140

Origin :  Switzerland                                                     Max Working Speed: 80 m/min


Model: CH-9555,Tobel                                                 Normal working Speed : 40~ 60 m/min 

Overfeed Range: -5%  to +10%


Working principle :

    After completing the dyeing process from the dyeing m/c then the fabrics are ready for de-watering. In de-watering m/c tubular fabrics are mainly processed. There is a magnetic sensor which scene the twist of the fabric and its direction and turn the fabric in opposite direction to remove twist automatically. Here dewatering is performed   De-watering is the process to remove the water from the fabric completely by squeezing and it is done by the padder. A suitable expander is used before the fabric is passed through the nip of the padders, which expands the fabric flat wise and adjust the width.

The expander width is adjusted as S/J- 20%, PK-25%, Int.-35%, Lacoste-40% wider than the required width. There is a pair of rubber coated padder, where water is removed from fabric when passed through the nip of it.

Normally squeezer contain single or double padders where,

    –  One for removing water and

    –  Other for applying finishing chemicals such as softener.

But this finishing is done only for the tubular fabric. Open widths knitted fabrics are applied finishing treatment later in stenter.

 Here present the compressor which given compress air to form ballooning before passing through the padder. This balloon remove crease mark but not form the maximum balloon otherwise shrinkage increase.

In feed & Out feed traverses which present in albatros control the following functions by over feeding system.

–             To control the width (dia) of the fabric.

–             To control the spirality of the fabric.

–             To control the crease mark of the fabric.

–             To control the length of the fabric.

Operational parameter:

–          Speed: As much as possible (40-60 m/min). Higher the GSM lower the speed.

–          Over feed: As required. Higher the GSM higher the over feed.

–          Padder pressure: 3-7 bar as required. Higher the GSM lower the padder pressure.

–          Width: Fabric width is adjusted as per required width.

Different parts of Dewatering m/c :

N.B: Santex contains two baths. One for padder bath and another for softener bath where softener given 1 g/l . The softener bath capacity is 80 liters.

Special features of  Santex-ag m/c :

Working principle of dryer :

After de-watering then the fabric through the dryer. The main function of the dryer is given below,

–            To dry the fabric.

–            To control the overfeed system.

–            To control the vibration which increase the G.S.M.

This machine contains two chambers. Two mesh endless conveyors are placed lengthwise to the chamber named conveyor net and filter net, each chamber contain a burner, which supply hot air .This hot air is guided through the ducting line by suction fan .There are nozzles placed in between filter net and conveyor net. When the fabric pass on the conveyor net, hot air is supplied to the wet fabric to dry it. There are exhaust fan which such the wet air and deliver to the atmosphere through the ducting line.

The speed of the dryer depends on the temperature of the m/c & the G.S.M of the fabric . If  the m/c temp. Is high then m/c speed also high and the m/c temp. Is low then m/c speed also low. The vibration speed of the m/c for heavy fabric is 730 m/min and normal fabric is 480 m/min .

Following tings are also considered incase of Dryer machine:

*  If fabric is more Redder than the standard one, then reduce the temperature.

*  If fabric is more Yellower than the standard one, then increase the temperature.

*  If fabric is more Bluer than the standard one, then increase the temperature.

All this data’s are practiced in mills which may vary factory to factory.

C. COMPACTOR  MACHINE: (M/C Specification)

Brand Name: Santex ag                                                Year of Manufacture: 1998                  Company: Santex ag                                                      Type: Santa spread 140, Withoutwinder

Origin:  Switzerland                                                       Max. Working Speed: 50 m/min

Model: CH-9555,Tobel                                                 Min. working Speed: 5 m/min 

Overfeed Range: -5% to +50%                                   Working Speed: 15~25 m/min

Max. Temperature: 1000C~1390C                                                     


Working principle:-

The main object of compactor is to make the fabric surface smooth, to control the residual shrinkage, G.S.M and if required fabric width also. To control the residual shrinkage the fabric is previously shrinkage artificially by gathering of loops of knitted fabric and it is set by heat and pressure.  In tube compactor, the dried tubular knitted fabric is face to steam when it passed through the teflon coated conveyor belt. When a cotton fabric absorbs water, it swells and shrinks (particularly in length direction) because the absorbed water allows the cellulose chains to move relative stain free position. Then the fabric is passed through the expander. This m/c contain two compaction units to compact both side of the tubular fabric. Each unit contains a hot rotating cylinder, blanket which rotate in contact with the cylinder and Teflon cover .while passing the expander roller, the fabric is over feeded. The fabric is compacted with the pressure of blanket and Teflon cover while passing through the hot cylinder .Due to compaction stitch length is reduced. Then the fabric is passed through the counting device .Before packing, the fabric is inspected carefully.

Important parts:-

                          -Over feed roller.                         – Steam sprayers.

                           -Expander.                                  – cylinder (2)

                           -Blanket (2)                                – Teflon covers.

Operational parameter:-

    – Set the temperature at 110-1390C (as required)

     – Set the overfeed % as required; to increase GSM, overfeed need to    increase to a certain limit.


                 Shrinkage control

                 – GSM control

                 – Width control

Special feature of Santex –ag Compactor :

–            Operating system is computerized.

–            Steam bar present which soften the fabric for compacting.

–            In compacting zone, edge & retard roller, compacting shoe and steel plates are present.

–            A pair of pulley present for fabric dia control.

–            Fabric G.S.M, shrinkage and dia control.

Parameters Used For Different Constructed Fabric :

N.B:  All this data’s are suitable for this machine only. All this parameters are suitable for. Grey G.S.M   range 140~160 to get Finished G.S.M 170~185 without Lycra Fabric

Following things are also considered incase of compacting machine:  

        * If fabric is less Reddish than the standard one, then increase the   temperature, reduce steam.

        * If fabric is less Yellowish than the standard one, then increase the temperature, without steam.

        *  If fabric is less Blueish than the standard one, then reduce the temperature, increase steam.

 N.B: Overfeed    Steam   G.S.M

Overfeed   Steam   Stretch    G.S.M

          Teflon speed (+)More compaction

          Teflon speed (-) – Less compaction, G.S.M    because overfeed is less.

 N.B: ® To remove twisting the tube fabric may be heat set before compacting.

          ® For Viscose with Lycra more overfeed required.

All This data`s are practiced in mills which may varied factory to factory.

Garments Export Procedure:

 1.Price Quotation/Costing/Production Space:

This is the first step of exporting. Here, the Buyer asking for price, capacity and lead-time.

Costing of a garment depends on three issues:

Fabric Price i.e. Consumption of fabric per Garment

Accessories & Trimmings Cost

CM (Cutting & Making) Cost

The costing is made based on Tech-Pack sent by Buyer.

Tech-Pack (Technical Package)/Order Sheet/PDM (Product Development Manual):

 Garment Sketch: An image or sketch

BOM (Bill of Material) Sheet: Contain Accessories & Packing Type.

Size Specification Sheet: Contain size & shape of all parts & Accessories

Packing Detail: Contain package type, No of material in one package etc.

Hang Tag & Label Placement Details.

The Buyer may send a sample instead of Tech-pack. The price may fix after negotiation with manufacturer. The lead time (Time to complete an order) and production capacity also considered for order confirmation.

 02.       Order Confirmation:

After fixing the price, quantity and lead-time the buyer then send a confirmation order letter via email. This document only ensures the order is given to committed producer if terms & conditions are fulfilled.

 03.       P.O by Buyers:

P.O stands for Purchase Order. It is a Purchase document without Terms & Condition.

 04.       Sales Contract:

It’s also known as Dummy L/C. Before Maturity of Master L/C the producer may need money to buy raw material, for that reason this document works as L/C. Both side confirmation are needed to open this document

05.       Master L/C:

It is the guarantee of payment to the producer from buyer with terms & condition. The most secured process of payment making. Buyers Bank and Producers Bank both handles the L/C. It is open for large volume of goods.

 06.       T&A (Time & Action) Calendar:

The total Action Plan related with an order such as Raw material and Accessories booking, Back-to-Back L/C opening, Worker Training, Target fixing for daily production etc. For less lead-time more line setup P.P Meeting arranging

 07.       Fabric & Accessories Booking:

After calculating Raw material & Accessories demand producer need to book them in respected countries such as china.

 08.       Back-to-Back L/C Opening

It requires importing raw material. Buyer may fix it or not. It needs to open ASAP

 09.       Sampling:

Manufacturer for Buyers approval makes samples. Samplings are 5 types:

 a)      Fit Sample: Made with available Trims & Fabrics. It requires when Buyer need to check the ability of manufacturer to produce the garment. Measurement is the key factor of this sample because it is approved through inspecting by wearing a Dummy.

 b)      P.P (Pre Production) Sample: It is made with required fabric & trims Size and shape also maintain hardly. Without approval this sample by Buyer the Production cant is run. A swatch Card/Board also need to send which contain fabric sample, Trim sample.

c)      Production/Top Sample: During production random product is select and sends for approval of buyer. The buyer’s complains can be handled properly. It ensures least amount of faulty garments

 d)     Garment Test Sample: This sample is sent to Multinational Testing Firm for testing. Generally buyer fixes the testing firm.

 e)      Shipment Sample: Before shipment the Buyers QC (Quality Controller) test the garment by random choosing from the cartons. If every sample overcomes the tests the garments get permission for shipping to the buyer.

 10.       Fabrics & Trim in-house:

After receiving the fabrics and trims producer need to check them correctly

The quantity, desired quality and color of fabric is considered for inspection

Faults are needed to mark and inform the producer as well as buyer immediately

Similar shade fabric rolls must be separate for reducing defected garments making

The accessories and fabric must be sent to buyer (or buyers local office)  for approval

 11.       P.P (Pre-Production) Meeting :

This meeting is essential before production. Generally the Merchandiser, the Production Manager, Cutting Master, Pattern Master and QC (From factory and Buyer) are present in PP meeting. Everybody present the problems and aspects of the production and information related to the order. Merchandiser or respected person will solve or take steps to solve the problems.

 12.       Marker Making & Cutting:

Here marker is designed through CAD software with less amount of fabric wasting. Then the fabric is spread considering same color in one Batch .The challenge of cutting Master is to cut the fabric separately according to shade variation.

 13.       Numbering, Bundling & Sorting:

After cutting the cut fabrics are numbered, bundled and sorted for next step

The these bundled fabric are sent to sewing section

 14.    Production Line Setup:

The production managers then setup the production line for the production. It is fixed during P.P Meeting. It is important to produce more garments in least time

 15.       Bulk Production:

The cut parts of garment then sewn in different sewing line. Every line prepares a single part of garments, and by moving these parts the final garments can be obtained. More floor space required for more production.

Daily production report must be submitted to Merchandiser/PM for maintaining production according to the delivery date. The finishing and packing is done.

 16.       Inline Inspection:

Its very important inspection for garments to increase profit. In every production line one QC is required for checking the garments are sewn properly or not, the measurements are accurate or not. If any problem found the QC then send to the responsible operator to modify the faulty garment.

 17.       Sea Vessel/Cargo Booking:

When production is near to end and with confirmation of buyer the producer then gives a booking for sea vessel. Buyer may fix the logistic firm or not

 18.       Final Inspection Booking:

Before shipment the producer need to invite the buyer’s QC for final inspection. At least 7 days before the invitation must be sent.

 19.       Final Inspection:

The buyer’s QC the check the garments from the lot of cartons. He the choose number of cartons randomly then unpack. He may check 5-10 or more samples of garments and verify. If any problem found he then inform the buyer and buyer will take any decision. If everything is all right he will approve and the goods the ready for shipment.

 Multinational Testing Firm:

 Multinational Testing/ Inspection/ auditing firm is renowned firm all over the world. The test garments sample in different category and then publish a KPI (Key Performance Index). After proper testing and if all parameter fulfilled the requirement they submit an IC (Inspection Certificate) to the Producer.

Famous Testing Firms are following:

 Water Treatment Plant (WPT):

Water for a textile plant may come from various sources.  But this water can not be used directly in textile processing because it contains various salts. These salts are mainly the carbonates (CO32-), Hydrogen carbonates or bi-carbonates (HCO3), Sulphates (SO42-) and Chlorides (Cl) of Calcium (Ca2+), and Magnesium (Mg2+). These are called hardness in the water. These must be removed though water treatment plant.

Effluent Treatment Plant (ETP):

The effluent generated from different sections of a textile industry must be treated before they are discharged to the environment. Various chemicals and physical means are introduced for this purpose.

 There is large difference between the theoretical knowledge and practical experiences. This is truer in case of the study of Textile Engineering. Industrial attachment or, Industrial training is an essential part for textile education because it minimizes the gap between theoretical and practical knowledge. This Industrial training increases our thought a lot about textile technology. It also helps us to know a lot about industrial production process, machineries, and industrial management and made us suitable for industrial life. Besides it gives us the first opportunity to work in industry. So we can say industrial attachment prepare us for the expected destiny of practical life.

I have completed my industrial attachment from Mondol Knit Tex Ltd. During my two-month long industrial training at Mondol Knit Tex Ltd I got the impression that this factory is one of the modern export oriented dyeing knit garments industry of our country. This factory does not compromise in case of quality. So, they have established on-line and off-line quality control of each product. Besides, they also use the good quality yarn, dyes and chemicals in their production process. Due to this, it has earned a “very good reputation” in foreign market for its quality product over many other export oriented textile mills. It has very well educated and technically experienced manpower to get rid of any defect in production process. It has also a good organizational hierarchy.
