Filament yarns in the medium-to-fine count range are used in fabrics for apparel, and those in the very fine count range are more appropriate for hosiery and also for carpets, sportswear, and as industrial yarns for technical textiles. Spun yarns are suitable for shirts, trousers, suits, home textiles, and bed linen.
The physical and mechanical properties of a fiber, as the unit cell of a textile material, clearly contribute to a fabric’s mechanical properties. However, according to the spinning system used, the yarn structure and properties can be varied considerably to alter packing, surface, and mechanical properties. The fabric itself imposes another set of variables, such as sett and weave, to further diversify the overall list of fabric properties.
