Shortcomings of Superfiber Leather
Release time:
2023-07-07
Superfiber leather is a new kind of high-grade leather developed in synthetic leather. It has the advantages of wear resistance, cold resistance, air permeability, aging resistance, soft texture and beautiful appearance.
Natural leather is made of many collagen fibers of varying thickness, which are divided into two layers: grain surface layer and reticular layer. The grain surface layer is woven from very fine collagen fiber, and the reticular layer is woven from thicker collagen fiber. The surface layer of superfiber leather is composed of polyurethane layer which is similar to the mesh layer of natural leather, and the bottom base is made of superfine fiber non-woven fabric, which is very similar to the mesh layer of natural leather. Therefore, superfiber leather and natural leather have similar structure and properties. Compared with natural leather, superfiber leather has the following characteristics: first, folding fastness can be compared with natural leather. At room temperature bending up to 200000 times without cracks, low temperature (-20℃) bending 30,000 times without cracks. Second, the elongation is moderate. Third, tear strength and peeling strength are higher.
Superfine fiber is obtained by island fiber spinneret method. The so-called island fiber is composed of two components: sea and island, one on the section is sea, the other is island dispersed in the sea. After drafting, the sea component is dissolved and a continuous ultrafine island fiber bundle is obtained. Its fiber size can reach 0.0011 dtex, usually 0.06~0.1. Because the fiber fineness of ultrafine fiber is higher, the quality of the product is greatly improved. Therefore, the appearance effect of superfiber leather is the most similar to that of leather, and its thickness uniformity, tear strength, color brightness and leather surface utilization are better than that of natural leather, which has become the development direction of contemporary synthetic leather.
