3024

COURSE OBJECTIVES:

• To impart knowledge on quality evaluation of fabrics and garments

UNIT I	CONSTRUCTION CHARACTERISTICS & SAMPLING TECHNIQUES	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 Definition– random, biased sampling. Terms used in sampling. Sampling techniques for fibre, yarn and fabric. Moisture Regain and Moisture Content. Standard conditions for testing samples

UNIT II	MECHANICAL PROPERTIES	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. Fabric Abrasion Resistance – Martindale abrasion tester. Fabric Pilling - I.C.I Pillbox tester. Crimp– Influence of crimp on fabric properties–Shirley crimp tester

UNIT III	COMFORT PROPERTIES	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. ACCESSORY TESTING Seam strength and seam slippage testing. Peel bond strength testing-Button, Zipper strength testing. Colour fastness testing – Washing, Rubbing, Light, Perspiration fastness. Apparel dimensional stability – spirality

UNIT IV	LOW STRESS CHARACTERISTICS	9

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	9

Fabric inspection – 4-point system, 10 point system, classification of fabric defects, independent product quality certification, acceptable quality level, Inspection of garments and garment defects - sewing, pressing, finishing and packaging defects
