The difference between artificial leather and synthetic leather

Fake leather is the substitute material of natural leather, and there are common artificial leather, synthetic leather and regenerated leather.

The artificial leather is made of a fiber fabric as a base material, and a synthetic resin-based raw material is applied to the surface of the cloth to make a surface layer, and a leather-like composite material is produced. Its base uses city cloth, canvas, knitted fabrics, raised fabrics, recycled fabrics, chemical fiber cloths, and non-woven fabrics. Polyvinyl chloride, polyamides, polyurethanes, and polyolefins are widely used for synthetic resins. From the cross-section, the cloth heads of cloths can be observed.

Synthetic leather simulates the natural leather imitation leather material in terms of structure and properties. It is chemically processed from chemical raw materials. It is characterized by the impregnation of macromolecules with non-woven fabrics with continuous pore bonding as the substrate. Surface with a polyurethane microporous layer or a wear-resistant and decorative skin. Both the front and the back are similar to the leather, and the structure has a high microscopic uniformity, and has a certain degree of breathability and moisture permeability that leather has. In terms of structure, appearance and performance, it is closer to natural leather than artificial leather. It has a special odor when burned, rather than the burning smell of animal skins. Reclaimed leather is made by grinding the lower material of leather into a fine material, and then adding adhesive to re-press it, so it burns and also has a burnt odor of the leather. The cross section looks similar to the fibrous layer of the leather, but from the surface, even if Embossing also does not create deep pores of the shape of the dermis.

Whether it is artificial leather, synthetic leather or regenerated leather, the common feature is the regular shape, no disability on the surface, consistent pattern, and uniform texture. Its hygienic properties and physical and chemical properties are far inferior to natural leather.

The vast majority of leather products on the market use pigs, cows and sheepskins, so it is also very important to be able to distinguish the types of leather correctly. The surface of the pig's leather is round and thick, with deep pores and a certain angle. The round shape of the pores is a group of three; the bovine leather (usually referred to as yellow leather) has a round pore that extends perpendicularly into the leather. Close and even; Sheep's leather surface pores clear, shallow depth, pores were oblate fish scales.
