Microfiber PU synthetic leather is a nonwoven fabric with three-dimensional structure, which is made of microfiber staple fibers by carding and needling, and then it is made into microfiber leather by wet processing, PU resin impregnation, alkali reduction, grinding and dyeing. It has excellent wear resistance, excellent cold resistance, air permeability and aging resistance.

2. Artificial PVC leather

The first generation of PVC artificial leather is based on textile or knitting materials. Leather-like products coated with polyurethane resin have the characteristics of similar natural leather, bright appearance, soft texture, wear resistance, folding resistance, acid and alkali resistance and so on.

Note: The difference between PVC artificial leather and PU synthetic leather can be distinguished by soaking in gasoline. The method is to use a small piece of cloth, put it in gasoline for half an hour and then take it out. If it is PVC artificial leather, it will become hard and brittle. If it is PU synthetic leather, it will not become hard and brittle.

The development history of pu leather;

In 1970s, the synthetic fiber nonwovens appeared the processes of needle-punched netting and bonded netting, which made the base material have lotus-like cross-section and hollow fiber shape, and reached a porous structure, meeting the requirements of natural leather mesh structure. At that time, the surface layer of synthetic leather had been able to achieve microporous polyurethane layer, which was equivalent to the grain surface of natural leather, making the appearance and internal structure of PU synthetic leather gradually close to natural leather, and other physical properties were close to the indicators of natural leather, while the color was more vivid than natural leather. Its normal temperature folding endurance can reach more than 6,543,800 times, and its low temperature folding endurance can also reach the level of natural leather.

The appearance of superfine fiber PU synthetic leather is the third generation of artificial leather. With its three-dimensional structural network, non-woven fabrics create conditions for synthetic leather to surpass natural leather in substrate. This product combines the newly developed PU slurry impregnation and open-cell structure composite surface processing technology to give full play to the huge surface area and strong water absorption of ultrafine fibers, so that ultrafine PU synthetic leather has the moisture absorption characteristics of bundle ultrafine collagen fibers inherent in natural leather.

Therefore, it can be compared with high-grade natural leather in internal microstructure, appearance texture, physical characteristics and human wearing comfort. In addition, superfine fiber synthetic leather is superior to natural leather in chemical resistance, quality uniformity, adaptability to large-scale production and processing, waterproof and mildew resistance.
