Superfine fiber is the abbreviation of superfine fiber PU synthetic leather. It is a non-woven fabric with three-dimensional structure network made of superfine fiber short fiber through carding and needling, and then it is finally made into superfine fiber leather through wet processing, PU resin impregnation, alkali reduction, skin grinding, dyeing and finishing.
Super fiber leather is a kind of regenerated leather, which feels softer than leather. Super fiber leather belongs to a newly developed high-grade leather among synthetic leather, and belongs to a new type of leather material. Because of its wear resistance, cold resistance, ventilation, aging resistance, soft texture, environmental protection and beautiful appearance, it has become the most ideal choice to replace natural leather.
The appearance of superfine fiber PU synthetic leather is the third generation of artificial leather. The non-woven fabric of its three-dimensional structure network creates conditions for synthetic leather to catch up with and surpass natural leather in terms of substrate.
Combined with the newly developed processing technology of Pu slurry impregnation and composite surface layer with open pore structure, this product plays a huge surface area and strong water absorption role of ultra-fine fibers, making ultra-fine PU synthetic leather have the inherent moisture absorption characteristics of natural leather with fascicular ultra-fine collagen fibers. Therefore, no matter from the aspects of internal microstructure, appearance texture, physical properties and people's wearing comfort, Can be compared with high-grade natural leather.
In addition, superfine fiber synthetic leather is better than natural leather in chemical resistance, quality uniformity, mass production and processing adaptability, waterproof and mildew resistance.
