FT8691	TEXTILE QUALITY EVALUATION	LPTC

3003

OBJECTIVE:

• To infuse understanding of yarn, fabric and apparel testing methods

UNIT I	CONSTRUCTION CHARACTERISTICS	9

Basic fabric particulars – Measurement of ends and picks per inch, count of warp and weft, determination of the type of weave, measurement of length, width, thickness and Area density (GSM); warp and weft crimp measurements for spun and filament yarn fabrics, the cover factor calculations; Fabric sampling techniques

UNIT II	STRENGTH CHARACTERISTICS	9

Tensile strength measurement – ravelled strip test and grab test – mechanical and electronic measuring systems. Tear strength – importance – measuring systems. Bursting strength and its measurement. Ballistic impact strength. Universal tensile tester - principle and operation

UNIT III	COMFORT AND SURFACE CHARACTERISTICS	9

Fabric stiffness – principle of measurement of flexural rigidity; Drapeability – measurement of drape coefficient; Crease recovery measurement techniques. Wrinkle recovery assessment using standard grades; Principle and functioning of air permeability testers, water repellency, contact angle and fabric shrinkage testing; Fabric abrasion resistance – measuring technique; Fabric pilling resistance – methods of determination.

UNIT IV	SPECIAL CHARACTERISTICS	5

Fabric bending hysteresis testing; Shear hysteresis measurements; Fabric compression and decompression behaviour; Fabric surface roughness and friction measurements; Fabric tensile hysteresis measurements; Fabric flame resistance testing methods; Moisture and thermal characteristics.

UNIT V	FABRIC AND GARMENT INSPECTION	13

Fabric inspection – Manual, semi-automatic and Automatic Inspection systems, classification of fabric defects, independent product quality certification, acceptable quality level, MIL standards and final inspection. Inspection of garments for defects - sewing, pressing,finishing and packaging defects.

TOTAL : 45 PERIODS

OUTCOMES: The student will have knowledge on

• Methods by which the physical and mechanical properties of textile materials and products are measured and investigated
