Microfiber-an excellent material to replace natural leather
May 25, 2021
Microfiber leather is a newly developed high-grade leather in synthetic leather. Because of its abrasion resistance, cold resistance, breathability, aging resistance, soft texture and beautiful appearance, it has become an ideal material to replace natural leather.
Natural leather is "woven" by many collagen fibers of varying thickness, divided into two layers: a grain layer and a mesh layer. The grain layer is woven from very fine collagen fibers, and the mesh layer is made of thicker collagen fibers. Woven. The surface layer of the microfiber leather is composed of a polyurethane layer similar to the net layer structure of natural leather, and the base layer is made of microfiber non-woven fabric, and its structure is very similar to the net layer of natural leather, so the microfiber Leather and natural leather have very similar structure and properties. Compared with natural leather, microfiber leather mainly has the following characteristics: First, the fold fastness can be comparable to natural leather. It is 200,000 times without cracks in normal temperature bending, and 30,000 times without cracks in low temperature (-20℃) bending; second, the elongation is relatively moderate; third, the tear strength and peel strength are high.
The superfine fiber is made by the sea-island fiber spinning method. The so-called sea-island fiber is composed of two components as the structure of the sea and the island respectively. On the cross section, one component is the sea, and the other component is the island dispersed in the sea. After drawing, the sea component is dissolved to obtain a continuous super The fine island type component fiber bundle, the fiber denier can reach 0.0011dtex, usually 0.06~0.1dtex, which is more like the collagen fiber of natural leather. The sea-island fiber is produced through the production process of cutting short, carding cotton and needle punching. Spinning cloth. Because the fineness of the superfine fiber is higher, the quality of the product is greatly improved. Therefore, the appearance effect of microfiber leather is most like real leather; its thickness uniformity, tear strength, color vividness and leather surface utilization are better than natural leather, and it has become the development direction of contemporary synthetic leather.
