1. Animals go through a complex physical and chemical process from rawhide to leather, the main processes are soaking, meat removal, depilation, liming, degreasing, softening, acid soaking, tanning, retanning, cutting, leveling, neutralization, dyeing, fatliquoring, drying, softening, spreading, leather grinding, finishing, embossing and so on. To put it simply, animals are made of rawhide leather, and then in the grain layer with dyes (color paste or dye water), resin, fixing agents and other materials to make a variety of colors of glossy, coated leather called glossy leather. High-grade glossy leather has clear grain, soft feel, pure color, good air permeability, natural luster, thin and uniform coating; low-grade glossy leather has more disability, so the coating is thicker, the grain surface is not clear, the gloss is high, the feel and air permeability are obviously worse.
2. Aniline leather is a leather factory that selects high-grade leather from the leather that has been made into leather (no damage on the surface, uniform grain), and is made by light coating with water or a small amount of color cream and resin. it maximally retains the original natural pattern of the animal skin, the leather is very soft and plump, the air permeability is good, the color is bright and pure, comfortable and beautiful to wear, and a remarkable feature of identification is that it is black in case of water. Most of this kind of leather is painted in light color, and most of the imported clothing leather uses aniline leather, which is expensive. In the maintenance of this kind of leather must be very careful, should be strictly in accordance with the aniline leather operation procedures, otherwise it will bring irreparable losses.
3. Suede leather refers to leather with a fluffy surface. Generally with sheepskin, cowhide, pigskin, deerskin production, the use of leather front (long hair side) made by grinding leather called cashmere; the use of leather reverse leather (meat surface) made by grinding leather; the use of two-layer leather called two-layer suede. Because suede leather has no resin finishing layer, it has excellent air permeability and softness, and is comfortable to wear, but it is poor in waterproof and dustproof, so it is more difficult to maintain in the later stage.
4. The production method of frosted leather is very similar to suede leather, except that there is no fluffy fiber on the leather surface, the appearance looks more like water sandal paper, and the common ones are frosted leather shoes. Such as the use of sheepskin or cowhide front frosted leather is high-grade leather.
5. Imitation old leather and antique leather: the leather surface is deliberately made into a stale state after finishing, such as uneven color and thickness of the finishing layer. Generally, imitation old leather needs to be unevenly polished with fine sand paper, and the production principle is like stone mill blue denim cloth. In order to achieve its antique effect. And antique leather is often painted into a light background, dark and uneven clouds or irregular stripes, looking like unearthed cultural relics, generally made of sheepskin and cowhide.
