Along with the rising level of technology and process technology continues to emerge , leather industry has developed into everyday consumer products industry in important industries.
Earlier, in the luggage synthetic leather processing and footwear industry dominated session is PVC artificial leather, it is mainly through PVC adding plasticizers, stabilizers made of paste , after coloring gel coating after printing , embossing or embossed leather made multiple appearances with animals similar products. PVC artificial leather for its approximate natural leather , the appearance of bright , soft, abrasion, folding , acid , etc., from the 1970s to today , has been considerable scale.
However, since the PVC artificial leather breathability and moisture absorption are relatively poor development in recent years has been subject to certain restrictions . Currently all occasions the use of PVC , PU can become its substitute. Three categories of processing luggage bags Material : PU, leather, fabric . PU bags accounted for most of the share. PU is not only superior high strength and toughness, and resistance to aging , breathable, breathable, waterproof , oil is a kind of mature environmentally friendly materials.
PU leather PU synthetic leather that is material to the substrate from the felt , polyurethane coating solution was made . As the diversity of color , texture , good elasticity, and texture of natural features to be applied in many fields. Such as clothing production, luggage processing , footwear, automotive interiors, sofa, furniture and so on.
Production technology and skilled technology greatly reduces the cost of production of PU synthetic leather , in many parts of China have established a complete industrial chain . Waterborne polyurethane synthetic leather products which not only inexpensive , but also to make a push for environmental protection work . Because use of water-based ecological synthetic leather aqueous polyurethane resin synthesis, water instead of solvents, greatly improving the people for synthetic leather trust . PU synthetic leather material for further alternative especially handbags and luggage processing industries using traditional PVC synthetic leather material laid a solid technical foundation .
