properties of textile materials

The characteristics and properties of different textile and fabric materials. These include strength, flexibility, elasticity, softness, durability, heat insulation, low weight, water absorbency/repellence, dyeability and resistance to chemicals. Moreover, the influence of chemical composition and molecular arrangement of yarn and fibre properties and fabric structure on the physical properties of textile fabrics; the different fibre types; the materials used in different processes and the effect on materials as they are processed.
