Quality assurance system

Quality assurance procedure may be divided into two major parts:

  1. On line quality control.
  2.  Off line quality control.

On Line Quality Control:

On line quality control is done at different stages, such as :

Winding: Soft or hard package.

Warping: Color pattern, width of repeat, section repeat.

Sizing:  pick up %, size paste quality check

Weaving: Dropper check, loose warp check, reed mark, wrong denting etc.

Off Line Quality Control:

Sample collection:

One meter sample of every order is collected by online inspector .  Every sample is clearly identified with a sticker.

QC department checks the fabric in the loom and at that time the loom remains stops. He ensure the quality parameter such as free of hole or spot, reed mark, repeat size, width of fabric etc.

TEST PROCEDURE   

Fabric weight (G.S.M):

              The procedure for fabric weight test of finished fabric:

– M/C used: G.S.M. cutter.

-Frequency:          Every order.

-Procedure: 3 samples pieces are cut with G.S.M. cutter. Find their average wt.

                             Gram per square meter (GSM) = Average wt*100

                             Ounce per square meter (oz/yd2)=G.S.M.*0.0296

                   -Performance std:           According to buyer’s given std.

                   -In case of non-conformity:

To increase G.S.M.: Reduce width mechanically.

To decrease G.S.M: Increase width mechanically

Width Test:

 

                             Machine used       : Measuring tape.

          Frequency            : Every order & after every finishing process.

          Procedure             : Manual measurement by tape.

                   Overall width       : Total width.

Useable width      : Width without selvedge.

          Pref. Std.              : 150+2 cm or specified by the customer.

          In case of non-conformity:      Re-finish.

Tensile strength:

 

                    M/C used                      : Alphateus Tensile Tester.

 Frequency           : Every order.

 Procedure            : According to customers requirements.

 In case of non-conformity:     To increase tensile strength re-

Mercerize (increase of 5-10%) and re-finish.

Tear strength:

 

 M/C used             : Element Tearing Tester.

 Manufacture        : Messmer Instruments Ltd.

 Frequency           : Every order (only for 100% cotton light fabric).

 Procedure            :  According to customers requirements.

 In case of non-conformity: To increase tearing strength re-mercerize & re-finish.

Pilling Resistance:

 

M/C used              : ICI Pilling box.

Manufacturer       : James H. Heals.

Frequency              : Whenever required.

 Procedure            : BS 5811(36000 rear) ASTM D 3512.

Performance std      : Grade 4; Grade 3(For each fabric).

 In case of non-conformity: Re-singeing followed by resin finish.

Fabric inspection:

It is the responsibility of both the textile supplier and garment manufacturer to inspect all textiles to ensure their compliance with the buyer standard. Textile which are being exported to another country for use in the assembly of a finished product are required to be inspected by the buyer’s designed inspection service prior to shipment. It is the sole responsibility of the textile supplier to ensure that the textiles are inspected prior to shipment. For textiles which are to be assembled in the country of textile origin, inspection is required only if requested by the buyer. Once requested it is the responsibility of the textile supplier to ensure that the textiles are inspected prior to shipment.

The fabric control service will be divided in the following subgroups:

A. Pre-control: “feel” examination, appearance, verification of any unpleasant odorous,         colors, shades, weight, listing and ending; verification of dye uniformity between center and selvedge by means of a special fabric strip “sleeve” and dimensional checking by means of a steam test, production of the shade continuity cards.

B. Control: All textile inspections will be conducted in accordance with the 4 point system. The control consists in checking of fabrics on appropriate machines, permitting complete tension free sliding and measuring of the fabric.

The pieces will always be processed in rolls or humpback, never folded in order to avoid permanent creases in the fabric.

Tension free measuring will be carried out electronically with or without metric labeling on the selvedge and the accuracy will be guaranteed with a maximum approximation of 0.5%. Measuring will be expressed in yards.

References for pattern and finishing will be certified by a fabric swatch indicated by the Garment conductor, colors by colors chart/shade chart. This sample will be reference sample taken from the first delivery of the production or a sample taken from a sample piece. Sample dimensions will be such as to permit verification of all characteristics, pattern, colors, etc. of the fabric to be inspected.

TEXTILE SPECIFICATIONS AND EVALUATION

All textile inspections will be conducted in accordance with the Four Point System.

The Four Point System derives its name from the basic grading rules:

  1. No more than four penalty points may be assigned for any single defect.
  2. No more than four penalty points may be assigned to one linear yard, regardless  of   the number of defects within that one yard.
  3. Penalty point evaluation

Defects in both the warp/weft direction will be assigned points using the following criteria:

1 point                -Defects size not exceeding 3”

2 points              -Defects size exceeding 3” but not exceeding 6”

3 points              -Defects size exceeding 6” but not exceeding 9”

4 points              -Defects size exceeding 9”

  • A continuous defect running (9”) or longer shall be assigned four points for each yard in which it occurs within the shipment.

 ·     For continuous defects such as side to side shading, side-center-side shading, end to end shading, off shade, no penalty points shall be assigned. However, the entire roll shall be graded as “Second Quality” whole lot cannot be shipped.

The following fabric penalty point grading standards are to be used when inspecting all textiles. The standards are intended to be comprehensive; rise to occasion, whenever a specific fabric condition is mot described. When this occurs, the shipment will be aborted if the inspection was failed, and the inspection service will contact the garment contractor/supplier for disposition.

Running Defect:

  •   Any defects found to repeat and/ or run in a continuous manner will constitute a running defect. Any running defect will be assigned four penalty points for each yard in which the defect occurs. For a roll containing more than five continuous yards per100 linear yards with running defects, the whole roll will be graded as second quality and cannot be shipped.

Full width defects:

  ·   Any roll that contains more than six full width defects per 100 linear yards shall be graded as second quality and cannot be shipped.

  • No roll will be accepted as an A grade roll which contains a full width defect in the first or last three yards. This roll will be graded as B grade.

 ·    No roll will be accepted as first quality where baggy cloth occurs. A roll which exhibits a noticeable degree of looseness (waviness) or tightness along either or both selvedge or ripples, puckers, folds, creases in the body of the fabric and would prevent the fabric from lying flat when being spread in a conventional manner. This roll will be graded as second quality and cannot be shipped.

Holes And Dropped Stitches

 ·    A hole consists of two or more broken yarns and is considered to be a defect. A hole or a dropped stitch, regardless of size will be penalized maximum of 4 points.

Roll length verification:

  • Any roll of less than 30 yards in length shall be graded as second quality and cannot be shipped. The roll ticket length will be verified during the inspection

Points Calculation:

Textiles are evaluated on square yard consumption. The formula used to determine the point count level of a roll of fabric is as follows:

1. Individual piece:        Points per linear yard ×36”×100 square yard

                                         Cuttable width in inches ×inspected yard

                             =Points for 100 square yards

                                           Total points per linear yard × 36”×100 sqr yard

2. Average Shipment piece:

                                             Total inspected yards × average cuttable width

                                  =Average points per 100 square yard per shipment

 ·      The average point value per shipment should not exceed 20 points per 100 square yards and not contain any second quality / rejected roll.

 ·      A grade acceptance- Individual roll within 25 points per 100 square yards.

  • B grade acceptance- Individual roll within 26-30 points per 100 square yards.

 ·     Second quality /Rejected-Individual roll with in 25points per 100 square yards.

  • Maximum 20% of “B” grade fabric yards are allowed with in a shipment.

Limitations of the Report:

  • Because of secrecy act, the data on costing and marketing activities has not been supplied & hence this report excludes these chapters.
  • We had a very limited time. In spite of our willing to study more details it was not possible to do so.
  • Some of the points in different chapter are not described as these were not available.
  • The whole process is not possible to bind in such a small frame as this report, hence our effort spent on summarizing them.

Conclusion:

      What special in this report is that the information, data & description very much subjective & practical. So, one can easily have an idea about the whole weaving unit of BTL at a single look on it.

     For the eight weeks we gave our full effort to collect the available information and tried to learn about factory management system. This industrial training program is a big boost for us to deal our professional life in the near future.
