It can be dyed in a variety of bright colors; in addition, it has the appearance of animal fur, and various types of wild and cultured fur can be copied. But its biggest feature is not environmentally friendly, not easy to degrade, pollute the environment. Pure Aniline Dye-modified leather with no aniline but with aniline effect. Only the best leather in the world can fall into this category. People who really love real natural products like this leather. Five percent of the world's leather production falls into this category, with only a few grades of leather meeting these standards. This leather without any finishing, it may only be thinly coated with a layer of wax or lightly coated with oil to enhance the feel and appearance. Soft throwing or polishing with the machine is usually the last finishing step for this type of leather. All-aniline Like pure aniline leather, only some of the best leather in the world fall into this category. The only difference between this and pure aniline leather is that the raw material used will be slightly lower, with a thin protective layer on the surface, usually with wax and transparent pigments applied to the surface. Semi-aniline This leather requires a little more processing, a little finishing on the surface, a light spray of paint on the surface of the leather to make the color uniform and to conceal some of the original imperfections. This leather has good light and scratch resistance, and easy to clean. 10-15% of the world's leather production belongs to this leather. Most Class B leather meets this type of standard. Interestingly, aniline, semi-aniline and pure aniline leather is not necessarily full grain leather, nubuck leather is a typical fully polished aniline leather. A lot of discolored leather starts gently with sandpaper and flatten the grain. Shaving the grain surface part of the mill to remove the grain defects to reduce the impact, and then through different finishing methods to create a fake grain to imitate the whole grain leather leather. 18% of the world's leather production belongs to this leather. This leather after more processing, such as: scrub, sanding, embossing, paint to cover up the original blemishes, insect bites, barbed wire scratches, etc. injury can be removed before the matte finish. The first layer of leather is grained outer layer of leather, about 0.9 to 1.5mm, called the C grade leather to meet this type of standard. This kind of leather obviously needs to be polished, because there is no use other than making artificial grain instead of using the original surface. The remaining 65% of the world's leather production is not suitable for furniture, can only be used as footwear, clothes, belts, handbags and car upholstery. Full-grain grain intact, intact natural skin texture and clear visible leather. Just as the wood grain, wood, and scabs of wood should exhibit the natural qualities of the species to which it belongs, the leather should also exhibit the characteristics of the animal to which it belongs. The better the leather, the less decoration you need. The cheaper leather's original grain was ground off and coated with pigments, embossed with fake grain instead, which was not as soft as full grain leather. Although covered with a layer of paint, the original texture changes are still visible. Semi-grain side The leather grain layer only slightly worn part, but should remain in the entire leather surface that is not worn out that part of the grain, the grain can still see the natural pores and texture of the leather. Since the word Top Top is used in English, the term is the most confused in the leather industry. People guess "Top Top" means the best, top, not here, the word "Top Top" is used here because the top layer can be matte, painted and printed. Basically, half a grain of leather is not split skin. Cut the skin cut into several layers, with grain called the first layer of skin, followed by the second layer of skin, three skin, with the meat surface for the meat surface profile skin. With modern technology, it is possible to apply split-skin finishes, paints and embossing suitable for furniture. Of course splits are not as durable as head skins, but adjusting their thickness gives interesting results. The most challenging is to make them flexible. Unless otherwise specified, normally painted split skin can not be used as a seat cushion. Maintenance of knowledge of leather garments Note the following points: 1, to avoid contamination with grease and chemical solvents to prevent discoloration; 2, regular waxing or cream oil care; 3, usually do not fold the leather, should be hanger hanging; Do not expose to the sun; 5, Do not put the health ball storage, so as to avoid chemical reaction, so that the cortex hardens.
