Synthetic leather is generally divided into: The first is PVC (polyvinyl chloride), which burns to produce water, carbon dioxide, chlorinated compounds, and even chlorine gas; It is a mixture of polyvinyl chloride resin, plasticizer and other matching agents, coated or glued to the fabric, after a certain processing process and made of wake up products. In addition, there are double sided PVC artificial leather with plastic layers on both sides of the substrate.   The second is PE (polyethylene), which, when fully burned, theoretically produces only water and carbon dioxide. The third, and most common, is PU leather, which, when fully burned, produces water, carbon dioxide, nitrogen, and small amounts of nitrogen-containing compounds. Polyurethane artificial leather is divided into dry polyurethane artificial leather and wet polyurethane artificial leather. The so-called dry polyurethane artificial leather refers to the solvent based polyurethane resin solution volatilized off the solvent, the multilayer film and the substrate formed by the multilayer structure. The wet polyurethane artificial leather is a multi-layer structure with good air permeability and moisture permeability, and a continuous porous layer, which is made of solvent-based polyurethane resin and water film forming method.   Artificial leather can be divided into many types because of the different synthetic resin used in artificial leather, different types of base materials, different production methods, whether there is foaming and different uses. Now artificial leather by the use of synthetic resin, production technology and use of classification.

In the processing of microfiber leather, what kind of method and process is adopted in the processing of microfiber leather has a decisive influence on the color and appearance of microfiber leather. So, in the process of processing, leather processing can take what methods? Let's introduce this problem to you. The leather surface of microfiber leather can be processed into laser leather: also called laser leather, the latest leather varieties with various patterns etched on the leather surface by laser technology.   Water-dyed skin: refers to various soft skins made by bleaching and dyeing the head skin of cattle, sheep, pigs, horses, deer, etc. in various colors, falling loose on the upper drum, and polishing.   Printing or branding skin: The material is the same as the embossed skin, but the processing technology is different. It is the first or second layer skin with various patterns or patterns from printing or ironing.   Trimming skin: it is a poor first-layer skin blank. The surface is polished to remove scars and blood tendons on the surface. After spraying with various popular color skin pastes, it is pressed into granulated or smooth skin.   Patent leather: leather made by spraying various chemical raw materials with two layers of leather blank and then calendering or matting.

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 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!

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.

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. 

First of all, the odor problem, you know that the leather itself is made of animal epidermis, although in the late did how much processing technology or, more or less still exist some odor. Especially in the sun's exposure, the odor emitted is more serious. And microfiber leather material made of leather, often the smell is not so serious, but if you buy some inferior products, may give off a plastic smell, so we must keep in mind when buying. Second is the performance of the material, to know the car microfiber leather is in PU polyurethane added microfiber, so this material leather not only has a very excellent wear resistance, to a certain extent to extend the use of leather time, and in the breathability and flexibility are more outstanding, the delicate degree of touch is a great help. And these advantages, are the traditional natural leather can not reach. If you are interested Microfiber Leather for bags, 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℃.
