[0002] Bed sheets are one of the textiles used on the bed, also known as quilts and quilt covers. Generally, wide fabrics with soft hand feel and good warmth retention are used. The characteristics of the fabric are flexible changes in width, color and shape. According to the different raw materials used, there are two types: pure cotton and blended. Pure cotton sheets have good air permeability and moisture absorption, feel comfortable and soft, thick and wear-resistant. The warp and weft yarns are all single yarns, which are called yarn-woven sheets, and the yarns are interwoven with ply yarns as warp yarns and single yarns as weft yarns. It is called half-line sheets. Blended sheets include cotton / vinylon, cotton / polyester and cotton / linen products, which have the advantages of easy washing and quick drying, scratch resistance, strong wear resistance, etc. When processing sheets, due to the different sizes of different beds, large pieces of bed sheet fabrics need to be cut.
