[0002] In the production and processing of fabrics, in order to seek aesthetic or anti-counterfeiting effects, the fabrics are generally patterned. The existing pattern processing methods, depending on the material of the fabric, are generally flower roller printing and dyeing, hot dyeing, embossing, hot pressing, or directly weaving patterns through yarns of different colors when the fabric is spun or knitted; and some textile fabrics are generally sanded to form a short-pile effect on the surface. Fabric sanding is to rub the surface of the fabric with a sanding roller to grind out a layer of fluff on the cloth. Sanded bedding is soft, warm and comfortable to use in winter, and the price is relatively high.
