Whipcord is a compact, medium-weight fabric of prominent right-hand 63° warp-faced twill. It may be made of cotton and may be mercerized. It's often made of good-quality woolen or worsted yarn. May be of rayon, nylon, other manmade, or blends. Very serviceable. Used for suits, coats, and uniforms.
These cloths have prominent steep twill lines formed form the warp threads. There are more ends than picks. The cord-like appearance of the twill lines is enhanced by the choice of direction of twist and a clear finish. Whipcord is made in a wide range of qualities, usually from cotton and worsted yarns.
A term applied to fabrics of a wide range of qualities and commonly made of cotton or worsted. The characteristic feature is a more or less bold upright warp twill (often a 63' steep twill), which is accentuated by a suitable weave structure, more ends per unit length than picks, and a clear finish to an extent which causes the twill or warp threads to form a cord-like effect.
