Microfiber Synthetic Leather Leads The Development Direction Of Synthetic Leather Industry In China

Industrial production of artificial leather has been in the history for decades. With the continuous application of various new materials, its products are also constantly upgrading. Leather fabric from woven fabric to today's nonwovens, resin from PVC, acrylic resin to polyurethane (PU), fibre It also differs from ordinary chemical fiber to lotus root fiber and superfine fiber. In terms of product style, Artificial leather making From low to high grade, from profiling to simulation, its characteristics are getting closer to natural leather.

　 Superfine fiber Synthetic leather is developed on the basis of full analysis of natural leather. Microfiber synthetic leather is made from bundled ultrafine fibers and polyurethane through special processing. It is made of nylon superfine fibers similar to the structure and properties of bundled collagen fibers in natural leather. It is made of non-woven fabrics with three-dimensional network structure, and then filled with polyurethane with excellent performance and open pore structure.

　 Automotive interior applications are widely used.

Compared with knitted fabric and woven fabric, the advantages of ordinary fabric interior are easy to get material, good elasticity and permeability, and low cost. The disadvantage is that the material is rough in appearance, easy to stain and not easy to scrub, and the physical properties are very different from natural leather. It is easy to be damaged and can not meet the needs of high-end products.

The advantages of polyurethane superfine fiber synthetic leather are: tear strength, high tensile strength, easy surface cleaning, similar structure and natural leather, high price and poor applicability.

Compared with ordinary PU leather and PVC, the advantages of polyurethane superfine fiber synthetic leather are tear strength, high tensile strength, good folding resistance, good cold resistance, finished product is thick and full, simulation is good, and VOC (volatile organic compounds) content is low. The disadvantages are heavier than ordinary synthetic leather, and the cost is higher.

Ordinary PU leather uses fabric as the base cloth, with poor simulation and folding resistance without synthetic microfiber leather, but it has low cost, light weight, convenient processing and variety.

PVC artificial leather contains chemical components (especially plasticizers) which are highly harmful to the human body. The VOC content is relatively high. It is easy to volatilize at high temperature. It has strong rubber feeling, no touch and feel of natural leather, poor simulation, but low cost and convenient processing.

Microfiber synthetic leather has many properties on natural leather, and even some physical and chemical properties are superior to natural leather. It can be comparable to natural leather in fullness and handle.

The source of natural leather is limited, and its quality varies with the origin and location of raw leather. Natural leather has serious environmental pollution during processing, low yield and heavy weight, and easy to mold and rot.

The polyurethane microfiber has the advantages of light weight, good cutting performance, high automatic cutting, high yield, good resistance to mould, and better strength than natural leather. The product has uniform texture, wide source, and small smell of finished products, but its handle, air permeability and fullness are inferior to natural leather.

　 Leading the development direction of the industry

At present, Superfine fiber It has become the textile material often selected by textile production enterprises to develop high-grade textiles. Its use can effectively improve the grade and added value of products.

Microfiber has a very small linear density and high specific surface area, so that the fabric has high coverage, soft touch and comfortable clothing. Meanwhile, with the decrease of fiber size, the proportion of the scattered light on the fiber surface increases, which makes the appearance of the fabric lighter and softer. Because of the above characteristics, the main products of the microfiber development are modern suede products, imitation silk products, peach like leather, high density products and high efficiency cleaning cloth.

Microfiber can also be used for making artificial leather, advanced air filter, dust-proof mask, ski skiing sportswear, swimsuit and other moisture permeable waterproof fabrics. In twenty-first Century, the production technology of composite microfiber was developed rapidly, and the output increased. The fastest growth rate was polyester microfiber. Microfiber market prospect is very good.

Since 1950s, the main producing areas of synthetic leather and synthetic leather have been transferred from Europe and America to Asia. Judging from the development trend of the industry, China has gradually become the manufacturing center of synthetic leather and synthetic leather products. On the one hand, our country has the advantage of labor resources, and on the other hand, it is the growth of downstream demand.

In recent years, the product structure of China's synthetic leather and synthetic leather industry has been continuously optimized, and the speed of industrial upgrading is accelerating. In the development process, the market demand gap of high-end products is more prominent. On the one hand, the proportion of PVC synthetic leather and PU synthetic leather products is too large and is dominated by ordinary products, with a single species, serious homogenization, low added value of products, showing an obvious situation of oversupply, and enterprises take price competition as the main competitive means. 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 is decreasing. On the other hand, despite the rapid development of domestic microfiber synthetic leather technology, only a few enterprises can achieve industrial production at present, and the production of differential, functional and high-end products is limited. The market demand is growing at a high speed, and the supply of products is in short supply. Every year, large quantities of imports from Japan, Korea and Taiwan can not meet the market demand.
