For various reasons, PU Leather bags are the daily choice of most people. Is PU Leather bags good? The artificial leather produced with PU resin as raw material is called Pu artificial leather (PU leather for short), that is, PU leather. The artificial leather produced with PU resin and non-woven fabric as raw material is called PU synthetic leather (PU synthetic leather for short). PU leather bag is characterized by wear resistance and durability. If it is well maintained, its service life is very long. However, PU leather is of good or bad quality. Many big brand leather bags use high-quality PU leather. PU leather is generally the second layer of leather material whose reverse side is cow leather. A layer of PU resin is coated on the surface, so it is also called film coated cow leather. Its price is relatively cheap and its utilization rate is high. With the change of process, it is also made into varieties of various grades, such as imported two-layer leather. Due to its unique process, stable quality, novel varieties and other characteristics, it is the current high-grade leather, and its price and grade are no less than that of the first layer leather. Based on the principle of environmental protection, PU leather not only has the texture of genuine leather, but also is very strong and durable. Due to the influence of Animal Protection Association and the development of technology, the performance and application of PU leather have exceeded that of natural leather. Compared with leather, PU leather has the advantages of lighter weight, waterproof, not easy to swell or deform after absorbing water, environmental protection, light smell, easy care, low price, and more patterns can be pressed on the surface.

Regenerated leather has both the characteristics of genuine leather and PU leather, and is a very common leather fabric today. So what is recycled leather? Let's take a look at recycled leather. Regenerated leather is to pulverize leather or recycled leather raw materials into leather fibers of a certain size, and then mix it with natural rubber, resin and other raw materials, and then compress it into a filter cake; heat the filter cake to make the fibers on the surface layer. Melting is viscous, and each layer is extruded, bonded, dehydrated, dried, sliced, embossed and surface treated to obtain the final product. The regenerated leather has the advantages of moisture absorption and air permeability, and the good workmanship also has the advantages of leather-like softness, elasticity, light texture, strong resistance to extreme high and low temperature, and wear resistance. However, the strength of recycled leather is worse than that of leather of the same thickness, and of course it is worse than PU, so it is not suitable for leather goods with high stress such as shoe uppers. Recycled leather is the use of tanning waste and the scraps produced in the processing of leather goods, which are recycled and processed into high value-added products. As an interlayer, recycled leather replaces cardboard with its unparalleled texture, elasticity, toughness, moisture resistance and processing adaptability; as a fabric, recycled leather can exhibit various performance effects through embossing, printing, and PU compounding processes, which are widely used in a wide range of applications. It is used in the production of leather goods, furniture, book covers, etc.  

  The main ingredient of cowhide, sheepskin and pigskin is protein, so they are susceptible to moisture, peeling and worms. To this end, when wearing leather clothes, avoid contact with oily, acidic and alkaline substances.  Leather is best worn frequently and often wiped with fine flannelette. If you encounter rain, damp or mildew, you can wipe off water stains or mildew spots with a soft dry cloth. But do not rub with water and gasoline, because the water glue leather hardens, and gasoline can make the leather oil volatilize and crack.  The pu leather is wrinkled and can be ironed with an ironing fan. The temperature can be controlled between 60 and 70 ℃. Use thin cotton cloth as a lining when ironing, and keep moving the iron at the same time.  Leather loses luster, can be polished with leather polish, do not use shoe polish to wipe. In fact, it is not difficult to polish the leather, as long as you gently wipe it on the leather coat with a cloth dipping polish-twice. Generally, as long as every two or three years on a second light, in order to keep the leather soft and glossy, and can prolong the service life.  If the leather is torn or damaged, it should be repaired in time. If it is a small crack, you can apply some egg white on the crack, and the crack can be bonded.  When the leather is not worn, it is best to use a clothes hanger to connect it; of course, it is also possible to put it flat, but put it on top of other clothes, so as not to crush and wrinkle it and affect its appearance.  The faux leather should be hung before collection, not exposed to the sun, and can be ventilated in a cool and dry place. In order to keep the leather beautiful in color for a long time, you can apply a layer of milk or glycerin on the leather before collection, so that it can be stored for a long time without changing color.

Microfiber leather and ordinary PU difference, this is a lot of consumers are very concerned about the problem, today for you to explain. The difference in price. At present, the general price range of ordinary PU leather on the market is 15-30 meters, while the general price range of microfiber leather is 50-150 meters, so the price of microfiber is several times that of ordinary PU. The surface performance is different. Although the surface layer of microfiber leather and ordinary PU are polyurethane resin, and ordinary PU popular for many years will be much more in color and style than microfiber leather. But generally speaking, the polyurethane resin on the surface of microfiber skin has stronger wear resistance, acid and alkali resistance, hydrolysis resistance, and color fastness and texture than ordinary PU. The fabric material is different. Ordinary PU is made of knitted fabric, woven fabric or non-woven fabric and coated with polyurethane resin. Microfiber skin is made of microfiber non-woven fabric with three-dimensional structure and coated with high-performance polyurethane resin. The difference of substrate material, technology and technical level has a decisive effect on the properties of microfiber leather. Different performance. Microfiber leather is superior to ordinary PU in strength, wear resistance, moisture absorption, comfort and other performance indicators. In layman's terms, it's more like leather, more durable, and feels better. Market prospect. Due to the low technical threshold, serious excess capacity and fierce competition in the general PU market, the products are reduced in production and materials, which is incompatible with the increasingly upgraded consumption concept, and the market prospect is worrying. However, due to the high technical threshold and limited production capacity, the product performance is increasingly recognized by consumers, and the market has a large space to rise. Microfiber leather and PU represent the products of synthetic leather in different development stages and different technical levels, so they have a certain substitution effect. It is believed that with the recognition of more and more people, microfiber leather will be more widely used in all aspects of human life.

How to distinguish so many kinds of Leather? Today I will teach you how to distinguish. Leather kinds of leather have similarities in appearance and internal structure, such as horse skin and cow skin, cattle skin and yak skin, donkey skin and sheep skin, kangaroo skin and calf skin, etc. With the improvement of leather processing technology, leather can be beyond recognition after finishing, decoration and imitation embossing. Some of its original features are covered, and then after cutting, segmentation and exquisite sewing, it is almost difficult to identify what kind of leather it belongs to with the naked eye. In order to pursue profits, some manufacturers will take advantage of the similarities in the appearance of different leather to steal beams and change pillars or adopt matching methods in the production, such as using horse skin as cow leather, yak skin as cow leather, donkey skin as sheep skin, etc. In businesses, it is also common to hang the logo of "genuine leather" or "cow leather" on leather products. In order to promote their own products, individual salespersons did not make a detailed introduction, resulting in customers' wrong selection and purchase. Here are some common identification methods: Comparison between cow leather and horse leather: the pores on the surface of cow leather are round and extend straightly into the leather. The pores are tight and uniform, arranged irregularly, like stars in the sky; However, the pores of horse leather are oval, larger than those of cow leather. They are inclined into the leather in a vein shape and arranged regularly. The leather surface is soft and loose, and the color is dim and bright, which is not as good as cow leather. Comparison between cattle hide and yak skin: cattle hide has relatively symmetrical fine pores, while yak skin has relatively thick and sparse pores. Comparison between sheepskin and donkey skin: sheepskin has fish scale pores and feels better than donkey skin. In recent years, with the growth of people's knowledge about the medicinal properties of donkey skin, donkey skin is rarely used in handbags.   Compared with pig skin, cow skin has fine and dense pores, irregular arrangement, and smooth leather; The pores of pigskin are arranged in a triangle shape, and the cortex is loose.

PU leather will age, but it ages slower and is more wear-resistant than ordinary leather. The normal service life of PU leather is about 3-5 years. The full English name of PU is urethane, and the chemical Chinese name is polyurethane, also known as microfiber leather (full name is "microfiber reinforced PU leather"). It has extremely excellent wear resistance, excellent cold resistance, air permeability and aging resistance. It is one of the important materials of sofa and other furniture and has the characteristics of modern style. Due to the influence of the Animal Protection Association and the development of technology, the performance and application of polyurethane synthetic leather exceed that of natural leather. After adding microfiber, the toughness, air permeability and abrasion resistance of polyurethane are further strengthened. There is no doubt that the performance of such finished products is quite excellent. Because of the unique technology, stable quality, novel varieties and other characteristics, it can be called one of the current high-grade leather, and the price and grade are no less than the first layer of leather.  

Leather: There is no harmful gas when burning itself, but a large amount of aniline dyes, chromium salts and other chemical reagents are used in the processing of leather. During the combustion process, there will be compounds that release nitrogen (nitrogen monoxide, nitrogen dioxide), sulfur dioxide and other harmful substances. Irritating gas, and the dermis is easy to chapped. PU Leather: burning will produce some harmful and irritating plastic gases such as hydrogen cyanide, carbon monoxide, ammonia, nitrogen compounds (nitric oxide, nitrogen dioxide, etc.) PVC Leather: Dioxin and hydrogen chloride are produced in the combustion process and production process. Dioxins and hydrogen chloride are highly toxic substances that can cause cancer and other conditions, and produce a pungent plastic odor. (The main odor comes from solvents, finishing agents, fatliquors, plasticizers and mildew inhibitors, etc.) Silicone Leather: no harmful gas is released, and the burning process is refreshing and odorless.  

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.

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.  

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.

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 advantage of PU leather? PU leather has several advantages over genuine leather: 1. Cost-effective: PU leather is generally more affordable than genuine leather. It provides a leather look and feel at a lower price point, making it a more budget-friendly option. 2. Animal-friendly: PU leather is a synthetic material that does not involve the use of animal hides. Therefore, it is a cruelty-free alternative to genuine leather, making it appealing to individuals who have ethical concerns about animal welfare. 3. Durability: PU leather is highly durable and resistant to wear and tear. It can withstand regular use and is less prone to cracking, peeling, or fading compared to genuine leather. It also tends to be more resistant to stains and is easier to maintain. 4. Wide range of styles and colors: PU leather can be easily manufactured with different styles, textures, and colors. It provides a versatile option for a variety of designs and aesthetics, allowing for more choices in terms of fashion. 5. Easy maintenance: PU leather is relatively low-maintenance. It is not as susceptible to moisture damage as genuine leather and can be easily wiped clean with a damp cloth. It does not require special conditioning or treatment to keep it in good condition. 6. Consistency: PU leather is manufactured, which means it has a consistent texture and appearance throughout the material. Genuine leather may have natural imperfections and variations, whereas PU leather offers a more uniform look.   Is PU more sustainable than leather? PU, which stands for polyurethane, is a type of synthetic material used as an alternative to leather. When comparing the sustainability of PU and leather, there are several factors to consider: 1. Environmental Impact: The production of leather involves raising livestock, which requires land, water, and feed. It also contributes to deforestation and greenhouse gas emissions. On the other hand PU is a petroleum-based material, which relies on non-renewable resources. The production of PU also involves the use of chemicals and energy. Both materials have environmental impacts, but the extent may vary depending on factors such as the production process and the management of waste and pollutants. 2. Animal Welfare: Leather is made from animal hide, which raises ethical concerns for those who are concerned about animal welfare. PU is a synthetic material, so it does not involve the use of animal products. 3. Durability: Leather is generally known for its durability and longevity. High-quality leather products can last for many years, reducing the need for frequent replacements. PU can also be durable, but the quality and longevity may vary depending on the specific product and manufacturing process. 4. Biodegradability: Leather is a natural material that decomposes over time. In comparison, PU is not biodegradable and can persist in the environment for a long time. However, it is worth noting that the tanning process used to treat leather often involves chemicals that can slow down its biodegradation.   How to clean PU leather? PU leather is a popular alternative to genuine leather. Cleaning PU leather is relatively easy and straightforward. Here's a step-by guide: 1. Gather your cleaning supplies: You'll need a soft cloth, mild soap or detergent, water, and a small. 2. Dilute the soap or detergent: Mix a small amount of mild soap or with water in the bowl. Make sure to use a gentle formula without harsh chemicals or abrasives that could damage the PU leather. 3. Wipe down the surface: Dip the soft cloth into the soapy water and wring out excess moisture. Gently wipe down the PU leather surface, removing any dirt, stains, or spills. Be careful not to scrub too hard to prevent scratching or damaging the material. 4. Rinse the cloth: Rinse out the cloth with clean water to remove any soap residue. 5. Wipe again: Dampen the cloth with clean water and go over the PU leather surface again, removing any soap residue or remaining dirt. 6. Dry the PU leather: Use a dry, clean cloth to wipe away any excess moisture. Leave the PU leather item to air dry naturally in a well-ventilated area. Avoid using direct heat or sunlight to dry PU leather, as it can cause the material to crack or warp. 7. Optional: Apply a leather conditioner: If desired, you can use a PU leather conditioner specifically designed for synthetic leather. Follow the instructions on the product to apply it evenly and enhance the durability and appearance of the material. Remember, it's essential to always check the care instructions provided by the manufacturer, as specific cleaning methods or products may be recommended for your particular PU leather item.
