Physical testing laboratory consists of assorted equipments for testing the physical properties of textile materials. For fibres, the tests include those for wool and cotton fibre fineness, cotton maturity, cotton fibre bundle strength, the regaining of moisture and the identification of fibres by microscopes. For yarn, tests are provided on yarn linear density, lea strength, yarn twist, yarn friction, yarn hairiness, yarn abrasion resistance, and the crimp rigidity of synthetic yarns. Fabrics can be tested for abrasion resistance, air permeability, bursting strength, dimensional stability, pilling, snagging, tearing strength, water repellency, water resistance, warmth retention and water vapour transmission. Carpets can be tested for thickness, tuft withdrawal strength and dynamic loading. The laboratory is mainly for teaching and also supports research.
