Background

Corduroy is a cotton fabric which is cut and raised and has longitudinal pile strips formed on the surface, and the corduroy is named because the corduroy pile strips are similar to a cordgrass core; the corduroy raw material is mainly cotton and also blended with chemical fibers such as terylene, acrylon, spandex and the like. It features thick texture, soft hand feeling, good heat-insulating property, and is suitable for making decorative articles such as coat, shoes and hat fabric, curtain, sofa fabric, etc.

The existing corduroy weave adopts a weft double weave formed by interweaving two groups of weft yarns and one group of warp yarns, and the ground weave comprises plain weave, twill weave and the like. Corduroy is woven from a set of warp yarns and two sets of weft yarns, wherein one set of weft yarns (called ground weft) is interwoven with the warp yarns to form a pile-consolidated ground fabric, and the other set of weft yarns (called pile weft) is interwoven with the warp yarns to form regular floating wefts, and the piles are formed after being cut off.

The surface of the traditional weft double corduroy is provided with fluff which makes the corduroy very warm and comfortable, but the bottom surface is relatively flat and hard, and particularly the touch feeling is cool in winter, so the actual skin-friendly performance of the bottom surface is not enough.
