Microfiber synthetic leather leads the development direction of synthetic leather industry
the industrialized production of artificial leather has a history of decades. With the continuous application of various new materials, its products are also constantly updated. From woven fabrics to today's nonwovens, the resins used in leather base fabrics range from polyvinyl chloride, acrylic resin to polyurethane (PU), and the fibers range from ordinary chemical fibers to lotus root fibers and superfine fibers. In terms of product style, artificial leather has experienced the development from low-grade to high-grade, from profiling to simulation. It can form molded products with complex shape, accurate size and metal or non-metal inserts at one time, and its characteristics are more and more close to natural leather
microfiber synthetic leather is developed on the basis of full analysis of natural leather. Superfine fiber synthetic leather is made of bundle superfine fiber and polyurethane through special processing. It is made of nylon Microfiber with three-dimensional complex structure, which is similar to the structure and properties of bundle collagen fibers in natural leather, and then processed with polyurethane with open microporous structure with excellent refilling performance
it is widely used in the field of automotive interiors
compared with knitted fabrics and woven fabrics, the advantages of ordinary fabric interiors are that the materials are easy to obtain, have good elasticity and breathability, and the cost is low; The disadvantage is that the appearance of the material is rough, easy to stain, not easy to scrub, and the physical properties are very different from natural leather, which is easy to be damaged, and can not meet the needs of high-end products
the advantages of polyurethane microfiber synthetic leather are: high tear strength, high tensile strength, easy to clean surface, and similar structure to natural leather; The disadvantages are high price and poor processing applicability compared with ordinary fabrics
compared with ordinary PU leather and PVC, polyurethane microfiber synthetic leather has the advantages of high tear strength and tensile strength, good folding resistance, good cold resistance, thick and plump finished products, good simulation, and low VOC (volatile organic compounds) content. The disadvantage is heavier than ordinary synthetic leather and higher cost
ordinary PU leather uses fabric as the base cloth, with poor simulation and folding resistance, which is not as good as microfiber synthetic leather, but it has the advantages of low cost, light weight, convenient processing and various varieties
pvc artificial leather contains chemical components that do great harm to human body (especially plasticizers), with high VOC content, which is easy to volatilize under high temperature, strong rubber feeling, and no touch and hand feeling of natural leather. On the other hand, China's industry has developed rapidly in recent years, but the cost is low and the processing is convenient
microfiber synthetic leather has the characteristics of natural leather in many properties, and even some physical and chemical properties are better than natural leather, which can be comparable to natural leather in fullness and hand feel
the source of natural leather is limited, and its quality varies with the origin and location of raw leather. Natural leather causes serious environmental pollution during processing, with low yield, heavy weight and easy mildew and decay
polyurethane microfiber synthetic leather is light in weight, good in tailoring, and can be cut automatically. It has high yield, good resistance to mildew and denaturation, and better strength than natural leather. The product has uniform texture and wide sources, and the finished product has little peculiar smell, but its hand feel, permeability and fullness are worse than natural leather
leading the development direction of the industry
at present, superfine fiber has become the textile raw material that textile manufacturers often choose when developing high-end textiles. Its use can effectively improve the grade and added value of products
microfiber has extremely low linear density and high specific surface area, which makes the fabric have high coverage, soft hand feeling and comfortable wearing. At the same time, with the decrease of fiber size, the proportion of scattered light on the fiber surface increases, which will make the apparent tone of the fabric darker and softer. Due to the above characteristics, the main product varieties of microfiber development at present include modern suede products, silk products, peach skin suede, high-density products and high-efficiency cleaning cloth. Microfiber can also be used to make artificial leather, advanced air filters, dust masks, ski and water skiing sports clothes, swimming clothes and other moisture permeable and waterproof fabrics. In the 21st century, the production technology of composite microfiber has developed rapidly. On the one hand, due to the incorrect installation, the output has increased more, and the polyester microfiber has the fastest growth rate. The market prospect of microfiber is very promising
since the 1950s, the main producing areas of artificial leather and synthetic leather in the world have gradually shifted from Europe and the United States to Asia. Judging from the development trend of the industry, China has gradually become a manufacturing center for the production of artificial leather and synthetic leather products. On the one hand, only regular maintenance can ensure the measurement effect of the experimental machine in China, which has the advantage of labor resources; on the other hand, it is the growth of downstream demand
in recent years, the product structure of domestic artificial leather and synthetic leather industry has been continuously optimized, and the upgrading speed of the industry has accelerated. In the development process, the market demand gap of high-end products is relatively prominent. On the one hand, the proportion of PVC artificial leather and PU synthetic leather products is too large, and they are mainly ordinary products, with single types, serious homogenization, low added value of products, showing an obvious oversupply. Enterprises take price competition as the main means of competition. The overall bargaining power of enterprises in the industry is weak, which can not effectively transfer the rapidly increasing cost of raw materials, and the overall profit level shows a downward trend. On the other hand, despite the rapid development of domestic superfine fiber synthetic leather technology, at present, only a few enterprises can realize industrial production, and the production of differential, functional and high-end products is limited, while the market demand is growing rapidly, and the product supply is in short supply. Even if a large number of imports from Japan, South Korea and Taiwan can not meet the market demand every year
