Introduction to artificial leather and synthetic leather
The appearance of artificial leather is similar to natural leather, and it is cheap and has a wide variety of colors. It has been widely used in industrial and agricultural consumption and people's lives. The artificial leather produced in the early days was made of polyvinyl chloride coated on the surface of the fabric, and the appearance and performance were relatively poor. In recent years, polyurethane synthetic leather has been developed, which has further improved the quality of artificial leather, especially for low-base non-woven fabrics. For the woven fabric, the surface layer is made of polyurethane porous material to imitate the structure and composition of natural leather, and it has particularly good performance.
Artificial leather can be classified according to raw materials and can be divided into two categories: PVC artificial leather and polyurethane synthetic leather. Among them, in the artificial leather series, there are artificial leather, artificial lacquer leather, artificial suede leather, PVC plasticized film and other materials, in the synthetic leather series, the surface is coated with a polyurethane foam layer, and the appearance is very similar to natural leather. Wide application.
At present, PU leather and PVC leather are widely used. The foam layer of PU leather is made of polyurethane, and the foam layer of PVC leather is made of polyvinyl chloride. Its structure generally includes three parts: the base layer, the foam layer, and the coating layer. The base layer is usually composed of woven fabric, knitted fabric or non-woven fabric, and usually has a fluffing treatment to ensure the separation fastness from the foam layer. Because the physical properties of the foam layer and the coating layer cannot meet the application requirements of the bag, Therefore, it is necessary to play a role in enhancing the fastness through the intervention of the grassroots. Different foam layers can make the imitation leather material obtain different textures and have better wear resistance. With different embossing templates, it can show different patterns and have a more beautiful decorative effect.
