Dermis  Genuine leather refers to all kinds of original skins stripped from animals, such as cow skin, pig skin, sheep skin, crocodile skin, etc. The head skin is directly processed from the raw skin of various animals, or the thick skin of cattle, pigs, horses and other animals is cut into upper and lower layers after depilation, and the upper part with tight fibrous tissue is processed into various head skin. For example, the most common cowhide in life is divided into the first layer and the second layer. The second layer of leather, also known as film covered leather, is composed of the second layer of animal skin or leftover material broken and PU resin. The second layer of leather is generally weaker than the first layer of cow leather in toughness, feel and wear resistance. Although it has the quality of leather, it has no real leather.    Faux Leather Faux leather refers to artificial leather, or artificial leather. Common products include PU, PVC and microfiber. Sometimes some businesses like to add the word "leather" after these names when writing ingredients on the label to confuse the public. For example, PU leather and microfiber leather, but they are not genuine leather. Ultrafiber leather, ordinary PU and PVC are products of artificial synthetic leather at different development stages and different technical levels. The surface layer of microfiber leather and ordinary PU is polyurethane resin, Ordinary PU is made of knitted fabric, woven fabric or non-woven fabric as the base fabric, and then coated with polyurethane resin. The microfiber skin is made of superfine fiber non-woven fabric with three-dimensional structure as the base cloth, coated with high-performance polyurethane resin. The super fiber leather is generally superior to other artificial leather in the sense of imitation leather and practical performance.   In general, the price of leather products is higher than that of imitation leather products, especially the first layer of leather, which tends to give people the feeling that leather is better than artificial leather. In fact, this is not the case. In many cases, the price of leather is due to the scarcity of its sources and the cumbersome treatment process of animal skin. However, with the development of technology, many excellent properties of artificial leather can not be achieved by leather, such as WINIW microfiber leather, because it is firm and wear-resistant, Low loss, non killing, highly respected in Europe and the United States, has gradually become the preferred material to replace leather.  

Polyurethane is also present in the fashion world. In addition to fabrics that are made from polyurethane, the mutability of this material offers the possibility of using it in other areas of the fashion industry, such as polyurethane mannequins. Mannequins are an element that was incorporated into tailor shops and boutiques in the 19th century, and the purpose of these molds was to imitate human appearance as much as possible, in order to avoid the long hours of testing and measurement required when making a piece of clothing. The materials used have been changing since the beginning, evolving from the waxes and plasters of the beginnings to polyurethane systems, which offer a great versatility when imitating different finishes and materials.     Polyurethane Takes the Fashion World by Storm From the New York runways to glossy magazine covers, polyurethane-based faux leather and suede are all over the fashion world. They can be found in almost everything from accessories and handbags to clothing items like shoes, jackets and pants. Material Innovation As polyurethane-based alternatives to products like suede and leather become ever more innovative, the fashion industry has taken notice.  More than a Vegan Alternative Designers are not only offering these products to consumers as a vegan alternative. Many fashionistas are finding that incorporating polyurethane into the designs provides a superior product for the consumer. These items, made from polyurethane faux leather and suede, are often more breathable, lightweight and water-resistant than those made from traditional leather or suede.  Taking a Cue from Automotive Design In addition to the fashion world, the luxury automotive industry has been quick to embrace the use of polyurethane in car interiors as well, finding the materials to be well suited to handle high volume usage; the material resists spills and temperature variations, while still maintaining its shape and luxurious feel. Not Just A Niche Market One luxury handbag line owner who got her start designing automotive interiors bucks the term “vegan leather” when discussing her handbags. She insists the polyurethane material she uses is far superior and completely different from traditional leather. With her line of bags, she hopes to target the fashion industry as a whole, not just corner the market on animal-free products.
