PU leather and microfiber skin is a synonym, has been combined.
PU is the abbreviation of English urethane, chemical Chinese name "polyurethane".
Microfiber skin full name is "ultra-fine fiber reinforced PU leather." It has extremely excellent wear resistance, excellent breathable, anti-aging properties, soft and comfortable, has a strong flexibility.
Microfiber skin is the best artificial leather, striae and leather is very similar, feel a bit soft, it is difficult to distinguish between outsiders is leather or recycled skin. Microfiber skin, called the ultra-fine fiber simulation sofa leather, also known as recycled leather, synthetic leather is a new research and development of high-grade leather, not leather. Because of its wear, cold, breathable, anti-aging, soft texture and beautiful appearance, etc., has become an ideal alternative to natural leather. Natural dermis is composed of many different thickness of collagen fibers "woven" made of sub-surface layer and mesh layer of two layers, grain layer from the very fine collagen fibers woven from the coarse network of collagen fibers .
PU is a polyurethane. Polyurethane leather has excellent properties. In foreign countries, due to the impact of animal protection associations, coupled with the development of technology, polyurethane synthetic leather performance and application of more than natural leather. By adding ultra-fine fibers, the toughness and permeability of polyurethane, wear resistance has been further strengthened. There is no doubt that such a finished product, the performance is quite excellent.
Applications: luggage, clothing, shoes, vehicles, car cushion, car mats, furniture, imitation leather sofa
Features
Microfiber skin mainly has the following characteristics:
1, folding fastness and natural leather can be comparable. (-20 ℃) bending 3 million times without cracks (temperature resistance, good mechanical).
2, elongation moderate (skin feeling good).
3, high tear strength and peel strength (abrasion resistance, tearing force, high tensile strength).
4, from production to use will not have any pollution, environmental performance superior.
The appearance of superfiber skin most like leather, the thickness of the product uniformity, tear strength, color and leather surface utilization rate is also superior to natural leather, synthetic leather has become the development direction of contemporary. Microfiber skin surface if dirty, available high-grade gasoline or water scrub, must not be used with other organic solvents or scrub with alkaline substances to prevent damage to quality. Use conditions: heat setting temperature is not more than 25 minutes at 100 ℃, 120 ℃, not more than 10 minutes, 130 ℃, not more than 5 minutes.
PU leather and natural leather
Natural leather has excellent natural properties because it is widely used in the production of daily necessities and industrial products, but with the world's population growth, human demand for leather doubled, a limited number of natural leather has long been unable to meet this demand. To solve this problem, scientists began to study a few decades ago to develop artificial leather, synthetic leather, to make up for the shortage of natural leather. More than 50 years of research process is the history of artificial leather, synthetic leather to natural leather challenge process.
Scientists from the analysis of natural leather chemical composition and structure of the beginning, from the start of nitrocellulose lacquer into the PVC artificial leather, which is the first generation of artificial leather products. Scientists on this basis, made a number of improvements and exploration, the first is the improvement of the substrate, followed by coating resin modification and improvement. To the 20th century, 70 years, non-woven synthetic fiber needle-forming network, bonding into the network and other technology, the substrate has a lotus-like section, hollow fiber-like, to a porous structure, and consistent with natural leather network structure Requirements; the surface of the synthetic leather has been able to do microporous structure of polyurethane layer, the equivalent of natural leather grain, so that the appearance and internal structure of PU synthetic leather and natural leather gradually close to other physical properties are close to the natural leather Indicators, and color than the natural leather is more bright; its temperature at room temperature to reach more than 1 million times, low temperature folding can achieve the level of natural leather.
Following the PVC artificial leather, PU synthetic leather after 30 years of technology experts with great concentration of research and development, as an ideal alternative to natural leather, access to a breakthrough in technological progress.
PU coating on the surface of the fabric first appeared in the 1950s on the market, to 1964, the United States DuPont developed a PU for the upper synthetic leather. After 20 years of continuous research and development, PU synthetic leather in terms of product quality, variety, or yield have been on the rapid growth. Its performance more and more close to the natural leather, some properties even more than natural leather, with natural leather to the level of true and false, in human daily life occupies a very important position.
Domestic and international markets have appeared on the ultra-fine fiber polyurethane synthetic leather is the third generation of artificial leather. Its three-dimensional structure of the network of non-woven synthetic leather in the substrate to create a catch-up natural leather conditions. The product, combined with newly developed PU slurry impregnated with composite structure, has played a huge surface area of superfine fibers and strong water absorption, making the ultra-fine PU synthetic leather with a superfine beam Collagen fiber natural leather inherent moisture absorption characteristics, so no matter from the internal microstructure, or the appearance of texture and physical properties and people wearing comfort, and so on, and advanced natural leather can be comparable. In addition, the ultra-fine fiber synthetic leather in chemical resistance, quality uniformity, large production and processing adaptability and waterproof, mildew degeneration, etc. more than natural leather.
Practice has proved that the excellent performance of synthetic leather is a natural leather can not be replaced, from the domestic and international market analysis, synthetic leather has also been a large number of natural leather to replace the lack of resources. The use of artificial leather and synthetic leather bags, clothing, shoes, vehicles and furniture decoration, has been increasingly affirmed by the market, its wide range of applications, the large number of varieties, is the traditional natural leather can not be met.
PU leather products maintenance methods
Cleaning method:
1. Dip the water and detergent, avoid gasoline scrub
2. Can not dry-clean
3. Can only be washed, and washing temperature can not exceed 40 degrees
4. Do not use sun exposure
5. Do not touch some organic solvents
6.PU leather jackets need to wear bagging collection, not folding equipment
PU and artificial leather characteristics:
1. High strength, thin and flexible, soft and smooth, breathable and water-permeable, and waterproof
2. Low temperature still has good tensile strength and bending disturbance strength, good light resistance to aging and hydrolysis stability
3. Not wear-resistant, appearance and performance are close to natural leather, easy to clean decontamination, easy sewing
4. Smooth surface, can be a variety of surface treatment and dyeing, species diversity
