Twill is a type of textile weave that is most recognizable for its diagonal weave. This type of weave is achieved by passing the weft thread over one warp threads then again, under two more warp threads. Due to the diagonal patterns that it has, twill becomes heavy and durable, but it drapes pretty well.
What makes twill different than most of the fabrics that we have is the fact that the appearance of its front and back side differs from one another, unlike most fabrics whose both sides look the same. The front part of the fabric is used as the fashion side because it looks more appealing.
Some of the fabrics that are woven in twill weave include tweed, tartan, gabardine, denim, duffel, Florentine and merino. In the fashion industry, twill is used in creating jackets, coats, separates and office pants. In the home industry, twill is used in creating rugs, bed linen, table cloth and blanket.
