· Introduction: Aim and scope of testing, Sampling techniques for fiber, yarn and fabrics.
· Testing of Yarns: Yarn numbering and conversion system, yarn twist, tensile properties, various type of measuring instruments and their working principles, factors affecting tensile properties, elastic recovery
· Evenness testing of yarns, nature and causes of irregularities, principles and methods of evenness testing, evaluations and interpretation of evenness results
· Yarn hairiness, principle of measurement, measuring instruments.
Test for filament and textured yarn.
Testing of Fabric: Measurement of fabric dimensions and other physical properties such as thickness, weight, yarn crimp, fabric shrinkage, air-permeability, thermal properties, wettability, water proof-ness, and flame resistance, Fabric’s mechanical properties such as smoothness, stiffness, softness and shear, drape behavior.
· Test related to fabric appearance such as pilling, crease and wrinkle recovery, fabric handle and factors influencing, fabric comfort.
· Methods of identifying the class of dyestuff in powder form and on dyed/printed fabrics.
