In general, the thickness, density and distribution of the pores of the leather surface is to distinguish between the main basis for cow leather, pig leather, horse leather and sheep leather.
1, pig leather: leather surface pores round and thick, relatively obliquely inserted into the leather. Arrangement of pores is a group of three, the leather surface showing many small triangular pattern, each far apart, rough surface. Level three holes regularly arranged like a triangle in the leather surface of the skin thin and short fibers, fibrous tissue closer than cow leather, cow leather flexibility is better, but the wear resistance is higher than leather. Leather feel hard, shiny bad.
2, cow leather: cattle leather and buffalo leather are called cow leather, but they also have some differences. Cattle leather surface pores round, relatively straight extend into the leather interior, the pores close and uniform, irregular, as if the stars. Buffalo leather surface pores than cattle leather thick, compared with the number of cattle leather pores scarce, leathery relatively relaxed, as detailed plump cattle leather.
(1) cattle leather: leather pores close, round and small, fuller cortex, cortical fiber staggered evenly distributed and compact, but the arrangement without the law, fibrous tissue slender tight, anti-tension, high toughness, smooth leather, not wrinkle. Extend into the leather pores within relatively straight.
(2) buffalo leather: leather pores round and thick, pores relatively rare cattle leather surface pores than the yellow leather, fibrous tissue relaxation better than its yellow leather wear, but a thick skin; leather surface is relatively relaxed, than the yellow leather slightly rough.
3, Ma leather: close the pores formed shaped arrangement, skin laxity, as leather abrasion resistance, little tension. Surface pores is not obvious, when a closer look will find its oval, slightly larger than the pores of the leather, the ramp extending into leather, were the mountains shape regularly arranged; leather surface is relatively delicate, soft, but not as good as leather bright color, slightly gray.
4, sheep leather: leather grain pores of oblate pores clear, a few form a group, arranged in scaly.
(1) Goat leather: leather leather surface texture on a semi-circular arrangement of 2-4 new pores surrounded by a large number of small pile hole, thick leather fiber closely, hardwearing, soft and flexible, in leather clothing in common. Fine leather surface, fiber closely, there are a lot of fine hair hole, the pores semicircle, a few a group arrangement similar scales or zigzag shape, the pores clear; cortex elasticity, feel tough.
(2) Sheep leather: Leather panels thinner, feel very soft, small pores is oblate, several rows of pores constitute a growing row, evenly distributed, fine leather loose fibers do not wear it is not strong. Leather surface is relatively loose, but smooth and delicate, elastic, pores small, soft, but not as goat leather fastness.
5, leather and synthetic leather: no pores, such as the production into the pores have a uniform pore arrangement rule; in the case of imitation sheepskin, leather face is plump, smooth and delicate, feel solid, flexible, almost real, but a closer look also You can see traces of mold plastic pressure after. Leather and synthetic leather are woven or non-woven fabric made substrate, in combination with synthetic resin composite materials, is part of a natural leather-like plastic. They have soft, flexible wear characteristics, is widely used, but poor ventilation, no natural pores close look positive negative plate is a woven or non-woven, rather than animal skins backplane. In addition, leather and synthetic leather bad cold, too cold will harden, brittle hair.
