The term twill designates both a textile weave characterized by diagonal structural designs and the cloth made from that weave. The weave varied to produce broken or intertwining effects. Twill fabrics are usually firm and are used especially in suits and in sport and work clothes. Twill-weave fabrics are also used for linings, pockets, and mattress ticking. Serge, Gabardine, and Cheviot are major types of twill.
The weave reveals diagonal stripes, and also called rib or twill rib. Twill is strong woven cotton fabric with a warp twill construction, dark coloured warp and light (undyed) weft. Classical fabric for Jeans.
