The characteristics of the fabric are the flexibility of width, color and shape. According to the different raw materials used, there are two types: pure cotton and blended. Pure cotton bed sheet has good air permeability and moisture absorption, comfortable and soft hand feeling, thick and wear-resistant. Both warp and weft yarns are called single yarn bed sheets, and all of them are called full-length bed sheets with ply yarn as warp and single yarn as weft. The blended bed sheet has cotton / Uygur, cotton / polyester and cotton / hemp and other products, with the advantages of easy washing, quick drying, strong scraping, strong and wear-resistant. The length and width of the bed sheet are determined according to the size of the bed, with the distinction between Chinese and Western styles. Chinese style bed sheets are generally 210-228 cm long and 100-200 cm wide. The fabric is usually of heavy, variable or combined texture. Western style bed sheet is about 108 inches in length and 72, 80, 90 inches in width. Generally, plain weave or twill weave is adopted. The texture is thin and the pattern is mostly scattered. Some products are brushed, with good hand feel and warmth retention. The design and color of the bed sheet are all white, plain, stripe, printing, jacquard, brushed and so on.
