The introduction of pure cotton cloth sanding processing technology will show you a detailed understanding of pure cotton cloth

Sanding treatment is one of the functional treatments of textiles. After the fabric is sanded, the cloth surface is covered with a layer of plush, and it feels soft and warm. It is one of the important treatments for autumn and winter warm clothing or bedding. The traditional sanding process is sanding with emery rollers. Now many factories use brushing machines for sanding, or ceramic sanding machines for sanding. Sand skin sanding is to rub the cloth surface with sandpaper on the mechanical guide roller. The bristle roller of the bristle machine is equipped with fine brushes. According to different materials, there are carbon brushes and ceramic brushes, no matter which kind of sanding equipment. , It is to make the sanding roller or brush and the fiber surface produce strong friction force to form fine and tight fluff, and obtain the soft, rich, soft and comfortable hand feeling of cotton cloth, and the fluffy style like peach skin. But in actual production, there will be many problems, such as when should the sanding process be positioned, sanding before dyeing or sanding after dyeing, whether the process of singeing can be omitted, and there is a problem with sanding after mercerizing. There are a lot of issues such as no influence, the relationship between the choice of dyes and the feel of the sanding, what kind of sandpaper to choose, the number of sandings, and so on. It is necessary to think carefully and do research and experiment to correctly determine the positioning of the sanding process and produce high-quality products. 1 The product style and characteristics of the brushed cloth maintain clear texture, no lint and dust on the cloth surface; no difference in front and back colors; rich, soft and elastic hand feeling; fine and uniform suede without long hair; shrinkage and color fastness conform to processing Requirements; suede with peach skin; outstanding style with velvet-free look and velvet touch. 2 Positioning analysis of the sanding process in the dyeing and finishing process According to the final sanding requirements of textiles, the sanding process can be arranged in different sequences in the production process, but each sequence has its advantages and disadvantages, and the factory needs to be based on its own processing objects and requirements To choose. 3 Matters needing attention for sanding The cloth surface must be smooth and free of grains and wrinkles; the dry humidity of the cloth surface should be even and consistent; select appropriate sandpaper according to the texture of the cloth, and pay attention to the control of the angle, tension, and speed of the sanding machine; Sulfur dyes may not be used or used sparingly. Because the dye particles are coarse, it is easy to affect the suede effect and hand feeling; soaping after dyeing should be clean, and the textile sanding roller will cause cross-color; pay attention to the cleaning of the machine to prevent the falling fluff from staining other color cloths .
