The fundamental reason for the softness of leather is that during leather making, a leather simulation oil with a good degree of bonding with the leather fibers is introduced into the interior of the animal skin to form an oil film that fully covers the surface of the fibers in the leather, that is, between the surface of the fibers in the leather. It is separated by a layer of leather of suitable thickness to simulate an oil film, so that the friction between the fibers inside the leather is equivalent to the friction of oil molecules, so the leather will be very soft. The principle is similar to that of a sponge, except that the inner surface fibers of the dermis are separated by an oil film, so that there are slidable pores between the inner dermis, but its pores are smaller than those of a sponge, and the distribution of fibers on the inner surface of the dermis is not as good as that of a sponge. There are rules.    However, in the natural state, the oil introduced into the leather will gradually volatilize and lose over time, or the oil film will be damaged due to other reasons. If it is hydrolyzed in water or in a high temperature environment, the leather simulates the oil film of oil. If it is destroyed, the oil will be volatilized and lost, so the fibers inside the leather will stick to each other, making the leather hard and brittle. Therefore, when the inner oil film of the leather is destroyed or the oil is lost, the surface between the inner fibers of the leather should be re-injected with high-quality oil that forms an oil film.   If you are intested in PU Leather, please contact WiniwPULeather at www.winiwpuleather.com.  

Microfiber leather is the best artificial leather, leather grain and leather is very similar, feel a little soft, outsiders are difficult to distinguish between genuine leather or recycled leather. Microfiber leather, known as microfiber simulation sofa leather, also known as recycled leather, belongs to the synthetic leather in a new development of high-grade leather, not genuine leather. Because it has the advantages of wear resistance, cold resistance, breathability, aging resistance, soft texture and beautiful appearance, become the ideal choice instead of natural leather. Natural leather is made of many thick and thin collagen fiber "woven", divided into two layers of grain layer and mesh layer, grain layer by the very fine collagen fiber woven, mesh by the thicker collagen fiber woven. The normal life of the general microfiber leather in 3-5 years, the quality will be correspondingly longer. Generally rarely used for ten years. Some of the top microfiber leather is very technological content, will be more expensive than leather, used in high-end applications. The appearance of microfiber leather is most like genuine leather, and its products are also better than natural leather in terms of thickness uniformity, tear strength, color vividness and leather surface utilization, which has become the development direction of contemporary synthetic leather. If the surface of microfiber leather is dirty, it can be scrubbed with high-grade gasoline or water, but not with other organic solvents or alkaline substances to prevent the quality from being damaged. Microfiber leather use condition: heat setting temperature is not more than 25 minutes at 100℃, not more than 10 minutes at 120℃ and not more than 5 minutes at 130℃.

Mink  Generally mink is a very noble leather, less used in handbag design, usually used in clothing. There are two kinds of mink, American mink and European mink. The benefits are that the mink skin is rarely disabled, the mink skin is of average size and thickness, the fur is evenly distributed, and the color difference is small. There are also considerable differences between the fur of male and female mink. Male mink fur is big and thick, and the coats made from it have a sense of weight, while female mink is softer and lighter to wear, with more usage. The female mink has a narrower and smaller body, shorter hair, fine and lighter hair, long and lustrous surface hair, and more expensive finished products. Generally speaking, the female mink is good, but also according to the preferences of the buyer and with the style and choice.  Pigskin  Because the pig hair through the skin layer directly to the inner layer, so the pigskin breathability and moisture absorption than cowhide good. But the pores are coarse, into the "Pin" type, rough skin pattern, not as beautiful as cowhide, need to be processed to change the shortcomings. Yellow cowhide epidermis is thin, and hair is not dense, hair root into not deep. Skin to, fat glands, sweat glands are not developed, generally used for shoes, leather bags surface. Features: the thickness of pigskin, elastic enough. Buffalo hide hair is sparse, sticky surface rough, there are obvious papillary bumps and folds, the texture of the leather plate is more withered and thin, large and heavy area. Commonly used in making shoes and mechanical wheel belt, after processing to become soft before you can make bags.  Sheepskin  Goat skin fiber organization is more solid, soft and elastic good. Similar to the yellow cowhide, but thinner, the skin surface of the concave and convex lines clear, detailed, strong sense of leather. Sheepskin is similar to goatskin, but the hair bundle of fat glands, sweat glands are more numerous, made of manufactured products, especially soft, stretchy, feel like velvet, but low strength, easy to rot, can only do leather clothing, gloves, can not do shoe uppers and handbags.  PU leather  PU leather is a kind of artificial leather, is the English "ploy urethane", chemical Chinese name "polyurethane". He has excellent wear resistance, excellent cold breathability, and cheap, has become the most popular material for making leather clothing in recent years. And PU leather without the odor of leather, can be washed, easy to maintain, in line with international environmental requirements and composition standards, is a new generation of fashion fabrics. And PU leather is artificial leather, more in line with the love of animals, people and nature in harmony with modern values.
