Description
Technical Field
The utility model relates to a base cloth technical field specifically is a wearability sofa leather base cloth.
Background
The industrial production of the polyvinyl chloride opens up new raw material resources for artificial leather and promotes the development of the production of the artificial leather. The paste made of polyvinyl chloride added with plasticizer and stabilizer is easy to be colored, and after the coating is gelatinized, the paste can be made into various products with the appearance similar to leather through printing, embossing or embossing and printing. Although the air permeability and moisture permeability are not as good as natural leather, the leather has certain strength and wear resistance, and particularly has the advantages of simple production, rich raw materials, uniform product quality, convenient cutting and use, light weight, water resistance and low cost, so the leather is widely used for manufacturing clothes, shoes, hats, cases, furniture, ornaments and various industrial accessories, and is a plastic product similar to leather. The fabric is usually used as a substrate, a layer of resin mixture is coated or attached on the fabric, and then the fabric is heated to plasticize the resin mixture and is rolled, flattened or embossed to obtain the product. Is similar to natural leather and has the characteristics of softness, wear resistance and the like. Depending on the type of the covering, artificial leather for shoes, artificial leather for bags, and the like are used. Artificial leather is a plastic product that looks and feels like leather and can replace it. Usually, the fabric is used as a substrate and coated with synthetic resin and various plastic additives. The artificial synthetic leather is prepared by coating resin on a base fabric or soaking polyurethane resin in the base fabric and then performing after-treatment, and the performance of a leather base fabric directly influences the characteristics of the artificial synthetic leather, so that the production technology, equipment and quality level of the leather base fabric are the basis of good and continuous development of the artificial synthetic leather industry, and the fabric used as the artificial synthetic leather base fabric mainly comprises four types of organic woven fabric, knitted fabric, non-woven fabric and composite fabric.
