In our ordinary life, bags are actually considered one of the daily necessities, of which there are actually a variety of fabrics, today we will see, what are the classification of luggage fabrics? What to understand? Synthetic leather materials First of all, what is the classification of luggage fabrics, nowadays the market is more common is artificial leather, one of its characteristics is the relatively low price, and a variety of color options. At present in all aspects of operation is actually relatively wide, with the current industrial production continues to progress, nowadays the quality of artificial leather is actually progressing, the overall practicality has also been improved. Genuine leather material Previously we introduced artificial leather, and there is a material is actually genuine leather material, the use of natural animal skin. The characteristics of this is the overall texture is more saturated, and practicality is actually stronger, all aspects of the performance is also relatively good, but relatively speaking the style is relatively single. Canvas fabric Canvas can be used to make our common canvas bags, handbags and backpacks and other fabrics, he is mainly made of cotton or hemp as raw materials, this cloth feel thicker has a better wear resistance and water absorption, dirty and not easy to mold, so widely loved by the textile manufacturers. Fiber cloth type material This material can usually be used in the bag fabric, the same can also be used as lining material. And it has a variety of colors and patterns, and the overall wear resistance and water resistance are also good, naturally also favored by many manufacturers. Through our simple introduction, I think we actually have a certain understanding of what the classification of luggage fabrics.   If you are interested Microfiber Leather for bags, please contact winiwpuleather at www.winiwpuleather.com. 

Natural leather, artificial leather, recycled leather are the most common leather in life. Many people have such doubts - artificial leather is recycled leather? Below, we will answer this question for you. 　　What is artificial leather? 　　Artificial leather is on textile fabric base or non-woven fabric base, made by various different formulations of PVC and PU and other foam or lamination processing, can be made according to different strength, wear resistance, cold resistance and color, gloss, pattern pattern and other requirements, with a wide variety of colors, waterproof performance, neat edge, high utilization rate and relatively cheap price of genuine leather. 　　But the vast majority of artificial leather, its feel and elasticity can not reach the effect of genuine leather; its longitudinal section, can see the fine bubble holes, cloth base or surface film and dry artificial fiber. It is a class of material that has been extremely popular in the early days until now, and is commonly used to make various leather products, or parts of leather materials. Its increasingly advanced production process is being widely adopted for the processing and production of two-layer leather. 　　Nowadays, artificial leather, which is very similar to the characteristics of real leather, is produced and marketed, and its surface process is extremely fibrous tissue of the base material, almost reaching the effect of real leather, and its price is also comparable. However, leather and imitation leather (recycled leather and artificial leather) cannot be compared: unique hygiene (natural pores and fibers) and durability.

Water-based PU sofa leather is a new material used in the production of sofas, this material has the characteristics of waterproof, wear-resistant scratch-resistant, stain-resistant, etc. So if you want to give the sofa at home a big clean, how to do it? When cleaning the leather sofa at home, it is recommended to use a special cleaning solution cleaning method, which is suitable for cleaning a large area. Leather sofa is most afraid of contact with very strong corrosive chemical agents, therefore, in the choice of cleaning solution, it is recommended that the leather sofa with a special leather cleaning solution. Specific practice: the leather-specific cleaning solution and warm water, in accordance with the ratio of 1:10 after stirring, with a soft cotton cloth dipped in the dissolved solution after wringing, repeatedly wipe the living room leather sofa. After wiping the dirt, to use a clean, semi-dry cotton cloth and then wipe again. Also available eraser wipe method, with eraser cleaning living room leather sofa, mainly for cleaning living room leather sofa above the accidental scratch to the ballpoint pen scratches, or accidentally stained with ink. Specific practices: in the ballpoint pen scratches or stained with ink part, first wet with a few drops of water, and finally use the eraser to gently wipe. Avoid excessive force, resulting in living room leather sofa decolorization or scratching.

PU leather, is ordinary PU leather, polyurethane surface layer plus non-woven fabric or textile fabric, general performance and relatively low price. Microfiber leather, is microfiber PU synthetic leather, high performance polyurethane surface layer is attached to microfiber base cloth, with superior performance, especially wear and scratch resistance.       Microfiber leather and ordinary PU are products under different development stages and different technology levels on behalf of synthetic leather, so they have certain mutual 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.  

What is the material of pu leather? PU leather is made by treating the second and third layers of inner leather and defective leather of natural leather through a special film-making process, and covering the surface of the leather with a polyurethane PU surface layer, which makes the surface of the leather appear various colors and multi-colored. Various patterns, without losing the advantages of leather breathability and folding resistance, it has its own uniqueness in appearance and waterproof performance. The emergence of microfiber PU synthetic leather is the third generation of artificial leather. The non-woven fabric of its three-dimensional structure network creates the conditions for synthetic leather to catch up with natural leather in terms of substrate. Combining the newly developed PU slurry impregnation with open-pore structure and the processing technology of composite surface layer, this product exerts the huge surface area and strong water absorption of ultra-fine fibers, making the ultra-fine PU synthetic leather have a beam-like ultra-fine The inherent hygroscopic properties of natural leather of collagen fibers are comparable to high-grade natural leather in terms of internal microstructure, appearance texture, physical properties, and people's wearing comfort.

To avoid contact with oil, acid and alkaline substances, put the leather jacket in a ventilated place when you take it off, but do not expose it to the sun.  Wipe off water stains with a soft dry cloth, but be careful not to use water or gasoline. If you encounter rain, don't use gasoline to rub, because water will make the leather hard, gasoline can make the leather oil evaporate and dry, accelerating aging.  Leather jacket before the seasonal collection must be cleaned and polished, to the leather supplement "nutrition", so that the leather jacket to maintain a soft and smooth luster, to extend the life. The varnish available leather varnish, with a cloth dipped in some varnish on the leather jacket gently coated - two times. You can also send a professional store for better maintenance.  Collection is best to hang up, leather jacket outside cover a piece of cloth, do not fold, to prevent wrinkles in the leather jacket. If you put it in a box, it must be spread flat and do not put clothes on it.  If a leather jacket is torn or torn, it should be repaired in time. As a very seasonal fashion, leather coats are stored for a correspondingly longer period of time than other garments. Therefore, the correct maintenance and storage is particularly important. Leather clothing in the collection before preservation to dry a little, can not be exposed to the sun, hanging in a cool dry place through ventilation can be, can also turn out the lining to dry. In order to make leather clothing in a longer period of time to maintain the color beautiful, before the collection can be coated with a layer of milk or glycerin on the leather surface, so that long-term storage without discoloration. It is best to use hangers to hang in the closet to keep the leather jacket in good shape and prolong the life of the leather jacket, but do not hang with other tweed, chemical fiber clothing, available cotton cloth with the separation. It is also possible to put it in a box, but it is advisable to put it flat and not folded. This is because if you fold it for a long time, the wrinkle marks will be difficult to recede.  

Simulation leather is artificial leather, simulation leather with PVC, PU, PE and other film processing made of materials, with texture color gloss a wide range, good waterproof performance, wind and cold resistance, high utilization rate and cost-effective features, according to different strength, wear resistance, cold resistance and color, luster, pattern pattern made of simulation leather is widely used in the manufacture of clothing, shoes, leather goods, car floor rubber and other industries. Because of the innovation of the production process, in recent years the surface of the imported imitation leather on the market and almost similar to the real leather, made of it clothing, shoes, leather goods are also very popular with the public, but the cost is more expensive than the general artificial leather. Simulated leather in windproof, waterproof, wear-resistant performance better than genuine leather, and texture color gloss a wide range of clothing, shoes, leather goods and other industries have been widely used.    

Microfiber leather is the third generation of synthetic leather, compared with PVC leather and PU leather, its internal structure, performance, appearance and texture are better, compared with the real leather, its price is only 1/4-1/5 of the real leather, so in the past few years the microfiber leather industry has developed at a high speed, its application areas from the initial travel shoes, sports shoes to bags, shoes, car interiors, apparel and other fields, the consumption compound growth rate in the past 10 years In the past 10 years, the compound growth rate of consumption is more than 30%, and in the past 4 years, it is more than 20%. Microfiber leather is a low carbon economy product of chemical science progress, it adopts advanced chemical science in the production process, not only save energy, and excellent product performance. And through a variety of technological innovation upgrade, microfiber leather in the production process can effectively control pollution emissions. With the strengthening of environmental awareness, and the protection of animal concept, the supply of natural leather will be greatly restricted. In addition, because the chemical science is also progressing, microfiber leather will carry out more process improvement in the future, microfiber leather is not going to be infinitely close to the real leather, but in more performance indicators to go beyond it. It is expected that in the near future, microfiber leather will occupy a broader market space!

The distinction between PU and PVC is still relatively easy. Judging from the corners, PU base cloth is much thicker than PVC, and the hand feel is different; PU has a softer hand feel, while PVC is harder; it can also be burned with fire, and PU has a much lighter smell than PVC. It can be distinguished by the method of soaking in gasoline: use a small piece of fabric, put it in gasoline for half an hour, and then take it out. If it is PVC artificial leather, it will be hard and brittle; if it is PU synthetic leather, it will not be hard and brittle. There are also some differences in the range of applications of the two materials. In footwear, PVC leather is mainly used for linings or non-load-bearing parts, or in the manufacture of children's shoes. PU leather can be used for footwear fabrics or load-bearing parts. For luggage, PVC leather is used more. This is because the items in the bag, unlike the feet worn by the shoes, do not radiate heat and do not carry personal weight.

Vegan leather mainly refers to synthetic products. Most vegan leather is not processed cowhide or sheepskin, but is made of PVC and PU. Of course, there are some innovative products based on natural ingredients, such as leather made from cork, tree bark, pineapple leaves or apple peel. Manufacturers of high-quality vegan leather argue that most of it looks exactly like the real thing, but it doesn't perfect over time like animal leather does. Why is vegan leather growing in popularity? Because environmentally conscious consumers don't just worry about food, they think about food, clothing, housing and transportation. There is a strong attraction to having an alternative that is almost identical to animal leather products and thus avoids causing animal suffering. Some companies are already making products that avoid animal skins, and Tesla is even launching a "completely vegetarian" car. They are turning to synthetic and natural materials to make leather.

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.  

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.
