The corduroy weave adopts the weft double weave of two sets of weft yarns and one set of warp yarns, and the ground weave includes plain weave and twill weave. Corduroy is woven from one set of warp yarns and two sets of weft yarns. One set of weft yarns (called ground weft) is interwoven with warp yarns to form a ground cloth that consolidates fluff, and the other set of weft yarns (called pile weft) is interwoven with warp yarns to form a regular float. Weft, which forms fluff after being cut.
Corduroy is woven by weft double weaving, and then finished by cutting pile. Corduroy uses a wide range of yarns. The warp yarn is usually 18-48tex (32-12 British count) single yarn, or 10tex×2-28tex×2 (60/2-21/2 British count) strands; the weft yarn is usually 14.5- 36tex (40-16 N) single yarn. The weave adopts the double weft weave of two sets of weft yarns and one set of warp yarns, and the ground weave includes plain weave, twill weave, and equal weft weight. Corduroy is a high weft density fabric, with a warp tightness of 35%-65% and a weft tightness of 110%-200%. The arrangement ratio of ground weft and pile weft is 1:2 and 1:3.
