What is the difference between synthetic leather and artificial leather, which is better? environmentally friendly synthetic leather can be roughly classified into two categories according to its raw materials; PVC (polyvinyl chloride) synthetic leather and PU (polyurethane) synthetic leather, which can also be derived from other types, depending on their different uses, different raw materials and different treatment processes, so that synthetic leather can have different appearance and characteristics.
PVC artificial leather: it is made of all kinds of cloth as the base material, combined with PVC foam layer, and then processed by leather. It has a soft handle, similar to the texture of the leather surface and different surface touch, durable and easy to process. It is a good and cheap product.
Artificial leather is the first substitute invented for leather fabrics. It is made of PVC, plasticizer and other auxiliaries calendered on cloth. Its advantages are low price, rich color, various patterns, and its disadvantages are easy to harden and brittle.
PU synthetic leather: It is a thermoplastic polymer. It can produce different characteristics by adjusting raw materials and processes. Non-woven fabrics and textile fabrics can be used as substrates to produce high quality products through multiple treatments. Its physical structure is similar to natural leather, and it has good durability, texture and air permeability. So it has a wide range of applications. It can be used in footwear industry, leather bag industry, furniture industry and sports equipment industry.
PU technology and Development Co., Ltd. is currently widely used in leather and PVC leather. PU leather foam layer material is polyurethane, PVC leather foam layer material is polyvinyl chloride. Its structure generally includes three parts: base layer, foaming layer and coating layer. The base layer is generally composed of woven, knitted or non-woven fabrics, and generally has wool treatment to ensure the bonding fastness with the foaming layer. Because the physical properties of the foaming layer and the coating layer can not meet the requirements of bag use, it is necessary to strengthen the fastness through the intervention of the base layer.
Different foaming layers can make the imitation leather material obtain different texture, and have better wear resistance. With different embossing templates, it can show different patterns and have more beautiful decorative effect.
