One of the three basic weaves Plain, Satin and Twill A fundamental weave characterized by diagonal lines produced by a series of floats staggered in the warp direction The floats are normally formed by the filling
The term twill means to double and twill was originally made by what is known as "doubling the plain weave" which was written as 1-up and 1-down Tweed or twill weave is written as 2-up and 2-down or 2/2, or 2/1 etc The twill effect is bias or diagonal on the face of the goods Left-hand twill runs from the upper left-hand corner of the fabric to the lower right-hand corner of the goods and vice versa for right hand twills
Twill is cloth, usually cotton, that is woven in a way which produces parallel sloping lines across it. strong cloth woven to produce parallel sloping lines across its surface (twilic , from twi- ( TWILIGHT) + -lic (from bilix, from bi- ( BI-) + licium )). One of the three basic textile weaves (see weaving), distinguished by diagonal lines. In the simplest twill, the weft crosses over two warp yarns, then under one, the sequence being repeated in each succeeding shot (row), but stepped over, one warp either to the left or right. In regular twill, the diagonal line is repeated regularly, usually running upward from left to right at 45°. The weave can be varied in many ways for example, by changing the direction of the twill line (as in herringbone twill) or its angle. Twill is much used for men's wear and many other clothing applications because it has stretch on both diagonals, which makes clothes comfortable even if closely fitted. Denim and many tweeds are of twill weave
