Microfiber leather, environmental protection leather, west leather = artificial leather, the surface covered, the surface seems flawless, but the actual comfort is low, low value cowhide = natural, unmodified, the surface is convex and convex, a symbol of noble and rich, high value, the price is dozens of times that of imitation leather.2

"Cowhide" is processed from cow skin, according to its physiological point of view, because its dermis contains a network of small fiber bundles, so it has considerable strength and permeability; The epidermis is located under the hair, next to the dermis, and consists of different shapes of epidermal cells arranged. The natural characteristics of cowhide are warm in winter and cool in summer, suitable for use in any climate, and have good feel, strong permeability, anti-static wear and other characteristics, so suede leather sofa fabric are very popular in Japan, Europe and the United States and other developed countries; Real cowhide, only through natural bleaching, so the stomatal density is thin, the air permeability is high, and there is a soft and comfortable feeling. On the contrary, inferior leather such as artificial skin or buffalo skin, after a variety of artificial spray coating, porosity is dense, forming a low degree of air permeability, and there is a rough feeling when touched.

Microfiber leather, environmental protection leather, west leather imitation leather, that is, artificial leather, seemingly smooth and beautiful, feel good, compared with cow leather from the surface is difficult to distinguish, but its bad spots :0 due to the surface film, poor air permeability, summer use is easy to form sweat stains on the back and buttocks :2 easy to fade, the surface film and leather between use to a certain number of years, will fall off, Defects at a glance :3 easy to break, the winter temperature is low, increasingly hardening, hardening uneven fracture, while the leather is without this defect.

Teach you to identify "waxy skin" and "oily skin"

Leather includes: full green skin, half green skin, waxy skin, cattle skin, buffalo skin, two skin, pig skin. Full green leather: that is, full grain leather, it is processed from high-quality raw materials, less disability, the natural state coating on the leather surface is intact, can show the natural pattern of the skin, wear resistance, good permeability; Full green leather is directly the blue warm leather made of dyeing, refusing too many chemicals, so the leather table can clearly see the fine pores, realistic, excellent air permeability, the price is the most expensive in the leather type, but you are not complex process and chemical materials, but in the quality of thick leather, full green leather and ordinary leather differences: That is, in the selection of the skin embryo must be used in captivity, and after castration of the bull skin, because the fiber tissue of the bull skin is relatively dense, and the width is larger, the most important thing is captivity, so that its skin scars are less, is the production of high-grade leather on the selection, followed by manufacturing, so that the overall effect is more noble and elegant! All green skin can only be imported, China can not do such a process! Full green skin is one of the best papillae, the market is rare. Semi-green skin: The surface is lightly polished and coated by a peeler, and the corresponding pattern is pressed on it. The coating is thin, wear-resistant and gas-permeable. Half green skin is also a kind of Italian skin, this skin is more common, especially high-end furniture. Cowhide: compared with semi-green, the coating is thick, the surface is light and deep, and the natural cowhide with disability or roughness is "cosmetic", and the wear resistance and air permeability are worse than that of semi-green. 0.9~1.0mm is thin skin, 1.3~3.0mm is thick skin; The cowhide is divided into two layers, the first layer is cowhide, most of the imported suede leather upholstery is this kind of skin, cowhide is the best domestic skin, good cowhide and imported poor skin, the quality is similar:

Buffalo skin: the second layer of buffalo skin is buffalo skin, buffalo skin pores are thick, feel soft and greasy, there is a rich skin taste! Wax leather :(wear-resistant, breathable) effect is similar to semi-green leather, it is processed by special chemical materials and special processes, and presents different color effects through different tension: wax leather is a very special style of leather, it will change color and have an antique effect, the whole is an "old" effect

Two layer skin: with the skin machine split layer, after coating or film and other processes made, fastness, wear resistance is poor. The broken skin is polished and then glued together, that is, the two layers of skin, the two layers of skin is generally hard, the feel is not good, there is a thick crack smell

Leather is generally caused by cowhide, divided into imported leather, domestic leather two categories: imported leather can be subdivided into imported pipi and imported Thai leather two, imported pipi (Italy) than imported Thai leather (Thailand) better.

Domestic skin: cow skin, buffalo skin, two layers of skin, pig skin artificial leather including: microfiber skin (rawhide), environmental protection skin, west skin, hard skin, imitation skin * Imitation skin is actually PVC plastic, but the surface is made into skin pattern only! The quality of imitation leather is determined by the thickness, the national standard stipulates: thickness 0. 65MM--0. 75MM. The average imitation skin thickness is 0. 7MM, with a thickness of 1. 0MM, 1. 2MM, 1. 5MM, 2. OMM's, the thicker the skin, the better! The color of imitation leather is very important, it must be the same color or close to leather, such as the difference is relatively large, will seriously affect the quality of furniture! Imitation skin smells like God's water. * Hard skin is also a kind of PVC, generally used in the dining chair, the thickness is the most important factor to determine the quality, generally to "1". 5MM is good.

* West leather is a kind of artificial leather, mainly made of PVC, thick 1. Above 0MM. * Environmental protection leather is a new type of artificial leather, feel very soft, leather pattern and leather similar, the disadvantage is easy to fade, easy to break, summer will absorb heat.

* Microfiber leather is also called rawhide, is the best artificial leather, leather grain is very similar to leather, feel a little hard, outsiders are difficult to distinguish leather or rawhide, many manufacturers on the market to this skin as imported skin. The skin can be distinguished by the following methods:

1) With the hand touch, the soft feel is good leather, the hard feel of the skin is not good. 2) Fingers gently press the leather, good leather will leave thin and dense lines, lift the hand texture immediately restore the prototype, bad skin fingers after pressing the lines are thick, or there will be no change.

3) Smell the taste of the skin, no taste or taste sweet, is imported skin, taste very bad, there is a natural water flavor is domestic skin
