PU leather is the epidermis of polyurethane. Now widely used in luggage, clothing, shoes, vehicles and furniture decoration, it has been increasingly recognized by the market, its wide range of applications, the large number of varieties, the traditional natural leather can not be met. PU leather quality is also good or bad, good PU leather even more expensive than the leather, stereotypes effect good bright surface!
In China, people are accustomed to using PU resin as the raw material for the production of artificial leather called PU artificial leather (referred to as PU leather); PU resin and non-woven fabric as the raw material of artificial leather called PU synthetic leather (referred to as synthetic leather). Traditionally, these three kinds of leather are called synthetic leather. In the end how to name? Need to be unified and standardized to give it a more appropriate name.
Synthetic leather, synthetic leather is an important part of the plastics industry, is widely used in various sectors of the national economy. Artificial leather, synthetic leather production in the international development of more than 60 years history, China since 1958 to develop and produce artificial leather, which in China's plastics industry is the development of earlier industries. In recent years, the development of China's leather and synthetic leather industry is not only the growth of the equipment production line of production enterprises, but the output of products has been increasing year by year and the variety of colors has been increasing year by year. Moreover, the development of the industry has its own industry organization with considerable cohesion Can China leather, synthetic leather enterprises, including related industry organizations together, developed into a considerable strength of the industry.
Following the PVC artificial leather, PU synthetic leather through technical experts for more than 30 years of painstaking research and development, as an ideal alternative to natural leather, access to a breakthrough technological progress.
PU coated fabric surface first appeared in the market in the 1950s, and in 1964, the United States DuPont developed a PU synthetic leather for the upper. Japanese companies to establish a production line with an annual output of 600,000 square meters, after 20 years of continuous research and development, PU synthetic leather in terms of product quality, variety, or production have been rapid growth. Its performance closer and closer to the natural leather, and some properties even more than natural leather to achieve the true and false with the degree of natural leather, in the daily life of human occupy a very important position.
Today, Japan is the largest producer of synthetic leather. The products of several companies such as Kuraray, Teijin, Toray, and Zhongfang basically represent the level of development of the international community in the 1990s. Its fiber and non-woven fabric are manufactured in the direction of ultrafine, high density and high non-woven. The direction of PU production towards PU dispersion and PU water emulsion is developing. The application fields of products are continuously broadened. From the beginning, Areas of development to clothing, ball games, decoration and other special applications, throughout all aspects of people's daily lives.
