Essential Differences: The difference in price. Now the general price range of ordinary PU on the market is more than 15-30 yuan (per meter), while the price range of general microfiber skin is more than 50-150 yuan (per meter), so the price of microfiber is several times that of ordinary PU.   The performance of the surface layer is different. Although the surface layer of microfiber leather and ordinary PU is polyurethane resin, and the ordinary PU that has been popular for many years will have much more colors and styles than microfiber skin. But in general, the polyurethane resin on the surface of the ultrafiber skin has stronger wear resistance, acid and alkalinity, hydrolysis resistance than ordinary PU, and the color fastness and texture will be stronger.   The base cloth material is different. Ordinary PU is made of knitted, woven or non-woven fabric based on polyurethane resin. The microfiber leather is made of microfiber non-woven fabric with a three-dimensional structure as the base cloth, coated with high-performance polyurethane resin. The different materials, processes and technical levels of the base cloth have a decisive impact on the performance of the microfiber skin.   The performance is different. Microfiber leather is comprehensively superior to ordinary PU in terms of strength, wear resistance, moisture absorption, comfort and other performance indicators. In layman's terms, it is more like leather, more durable, and better feel.   The market prospects. Due to the low technical threshold, serious overcapacity and fierce competition in the ordinary PU market, the product is reduced and the material is reduced, which is incompatible with the increasingly upgraded consumption concept, and the market prospect is worrying. Due to the high technical threshold and limited production capacity, the product performance of the microfiber leather is increasingly recognized by consumers, and the market has a large room for growth.   Conceptual Differences: PU leather refers to ordinary PU leather, polyurethane surface layer plus non-woven fabric or textile fabric, the performance is general, the price is relatively low. Microfiber leather is a microfiber PU synthetic leather, high-performance polyurethane surface layer attached to the microfiber base cloth, superior performance, especially wear and scratch resistance.       Microfiber leather and ordinary PU are products of different stages of development and different technical levels representing artificial synthetic leather, so they have a certain substitution effect. It is believed that as microfiber leather is recognized by more and more people, it will be more widely used in all aspects of human life.

The process of producing microfiber leather mainly includes two parts:  wet processing and  dry finishing. The basic principle of the process is: the main component of microfiber is polyamide fiber, and according to data, the composition and structure of polyamide fiber is simpler than that of protein fiber, and only has carboxyl and amino groups at the end of the molecular chain. In the middle of the molecular chain, there are a large number of carbon chains and amide groups, without side chains. The amino content of polyamide fiber is low. The amino content of nylon 66 and nylon 6 are 0.04mol/kg (fiber) and 0.098mol/kg (fiber) respectively, which are about 1/20 and 1/10 of wool. The carboxyl content of polyamide fiber is higher than that of amino group. At the isoelectric point, the amino group exists in the form of-NH3 ion, while the carboxyl group only partially exists in the form of-COOH-ion. Aiming at the structure of polyamide fiber, acid hydrolysis and enzymatic hydrolysis technology are first used to chemically modify the superfine fiber, open its amide bond, and increase its active group; then use the retanning, filling, and filling of natural leather. Greasing and dyeing technology make the macromolecular tanning agent fill the superfine fibers, improve its water vapor permeability and other physical properties, and make the handfeel of the superfine fiber base cloth close to the real leather blank. The basic principle of dry finishing is to use natural leather finishing technology combined with synthetic leather finishing technology for different purposes of the finished product, using back cover-fine lines-grinding-surface-fine lines-top coating-embossing-The soft process route can form a microfiber sofa leather with a leather appearance. The wet film is used to form the following layer to endow the microfiber base cloth with a grain surface similar to the real leather blank. The microfiber leather manufacturer said that on this basis, various real leather coating technologies such as rolle.

Furniture of choose and buy, especially when high-grade sofa, it is emulative skin obviously but the sofa that tells you is dermal make it however, the price is not poor more. A lot of people are not clear how to distinguish the dermis in leather furniture and simulation skin, when this is buying leather furniture, it is a chief big problem. Here are some simple ways to do this: Touch method: Touch the surface with the hand, dermal feel is smooth and exquisite, soft elasticity is good, and copy skin feel is stiff, without elasticity. Press method: Press the surface forcibly with the finger, dermal force point sinks as the finger, form meticulous drapey pattern, after letting go, it can be restored quickly as is. And imitation leather due to the hard cortex, finger press force point will form a round pit, there is no wrinkle near, let go after the recovery is relatively slow. Popular point, if the skin grain to press the aggregation, that is genuine leather. Skin picking method: Is to use fingernails to pick on the skin, if the scratch will be restored immediately, basically can be sure that it is leather, if the recovery is slow or not, then it is artificial leather.

Microfiber Synthetic Leather   Synthetic Leather is a kind of leather made of Microfiber, which is a kind of artificial leather after the raw material is processed. The advantage is that Microfiber Synthetic Leather is closer to natural leather in texture and appearance than artificial leather, and has excellent breathability and synthetic leather is beautiful and lustrous, and lighter in quality, waterproof, not easy to swell after absorbing water, the most outstanding point is synthetic.   Microfiber Synthetic Leather is a kind of leather made by processing chemical materials, choosing non-woven fabric as the base material, then adding artificial coating material (PU) on the front and back side, the Microfiber Synthetic Leather has the same texture and appearance as the real leather. The difference between Microfiber Synthetic Leather and artificial leather is the difference between base material and coating, the base material of synthetic leather is non-woven fabric and artificial leather is textile fabric, the coating of artificial leather is PVC.   Advantages of Microfiber Synthetic Leather: First of all, the functional characteristics of synthetic leather are closer to natural leather than artificial leather, synthetic leather has excellent breathability and good luster, Secondly, it has excellent wear resistance than genuine leather, the products made of it are not easy to be damaged and have certain corrosion resistance, the key point is that synthetic leather is produced in large quantity and cheap, it can be used as a substitute for real leather.
