The difference between superfine fiber PU synthetic leather and traditional synthetic leather
Microfiber synthetic leather consists of two parts, polyamide fiber and polyurethane. They are closely joined together. In the fabric structure, superfine fibers are cross-linked together to form a skeleton and supporting structure, forming structures similar to those of dermal collagen fibers. Distributed around the fiber is polyurethane, which makes the entire synthetic leather fabric as a whole, and has many functions. It is not a simple filling in leather, but has many round, needle like foaming structure, and the whole is solid mesh. The structure of the hair groove is interlaced to form a micro transparent structure, so that the leather body has certain permeability and moisture permeability.
Superfine fiber PU synthetic leather is a new type of high-grade synthetic leather made of very fine fibers, each field can be used as shoes, bags, furniture, car interiors, and has the characteristics of leather leather than superior index. The three-dimensional network structure of nonwoven fiber superfine polyurethane synthetic leather base cloth is a recent development of a new generation of synthetic leather, it was called the fourth generation of artificial leather, can be comparable with the advanced natural leather, moisture permeability has inherent natural leather, and more than natural leather in chemical resistance, waterproof, mildew degeneration etc..
In fact, the fiber is fine, and then dissolved in solvent, polyurethane covered, on the fiber, between the fibers due to solvent out of the formation of a hole, it is breathable, breathable. The solvent is thinner and the polyurethane particles are fine. This property is not very special.
