Quality Control process in Textile

Quality control is an ongoing process, which starts right from the initial stages of fiber or yarn right upto finishing and final packing of the fabric.

1.        Setting up standards by which strict quality check-up can be maintained.

2.        Co-ordination with departmental people for ensuring quality standards.

3.        Implementation of quality standards among the departments.

4.        To take preventive measures for maintaining the quality

5.    Along with all the above functions, to provide the management with production of high quality or with defects within the tolerance limit.

Quality Control

Quality check up tests performed in different departments

Combing

1.          Fineness testing (micron)

2.          Length

3.          %Grease

4.          Foreign matter

5.          Moisture content at different stages

6.          Oil + total fatty matter (TFM)

7.          Neps

8.          Blend composition

9.          Unevenness% (u%)

Spinning

1.        Testing of sliver, roving, yarn for evenness uster meter

2.        Twist testing (TPM)

3.        Count testing (Nm)

4.        Moisture content testing

5.        Single yarn strength testing

6.        Lea strength testing

7.        Hairiness testing

Weaving

1.        Detection of faults usually on a running loom

2.        EPI and PPI in a grey fabric

3.        Study the causes for loom stoppage in different quality materials.

4.    Detection of faults like missing ends, missing picks, curly selvedges, temple marks & cuts, floats, wrong denting. Mending of all theses faults is done in the perching department.

Dyeing

1.   Approving the shade by visual checking 1st & then with the help of computer colour matching.

2.     Identification of visual faults in a piece dyed fabric on a perching table & retreating the fabric to remove the faults.

3.   Checking the dyed fabric for washing fastness, light fastness, sublimation test (only for polyester material) etc.

Finishing

1.        Width of the full finished fabric.

2.        Weight of fabric per sq. meter.

3.        Weight of fabric per linear meter.

4.        Piling test.

5.        Drape coefficient of fabric.

6.        Tensile strength testing.

7.        Seam slippage test.

8.        Washing & ironing test.

9.        Blend composition.

10.    Water repellence, oil repellence.

11.    Flame retardancy.

All the tests carried out in the quality control department help in giving the fabric an optimum quality as desired. They have the right to alter a particular process & take corrective measures in order to get an optimum quality fabric.
