What is PVC leather, PU, artificial leather, PU synthetic leather
Aug 16,2019
China leather, synthetic leather industry development, has become a new quite have the potential of development as well as industrial, highlighting the following a few features:
Artificial leather, synthetic leather, development is rapid, market increasingly widened
Nowadays, daily life design and color a wide variety of leather everywhere, such as interior decoration, sofa fabric, car interior, clothing, shoes and bags, etc, people tend to think that these products are natural leather making, actually otherwise, these leather quite a large share of occupied by artificial leather, synthetic leather.
In China, people habits will use PVC resin as raw materials to produce artificial leather called PVC leather (hereinafter referred to as artificial leather); With PU resin as raw materials to produce artificial leather called PU leather (hereinafter referred to as PU leather); With PU resin and non-woven as raw material to produce manufacturer called PU synthetic leather (hereinafter referred to as synthetic leather). For PU leather, PU synthetic substrate is, at this industry still does not accurately named, but someone habits on the above three collectively known as synthetic leather. Exactly how to name? To everyone to unity and standardization, to give it a more appropriate name.
Artificial leather, synthetic leather, plastic industry is an important part of national economic sectors, used extensively. Artificial leather, synthetic leather production internationally for 60 years of development history, China began in 1958, its development and production in China leather in the plastic industry is the development of earlier industries. In recent years, Chinese leather, synthetic leather industry development is not only the production enterprise equipment production line growth, product yield in successive years growth, varieties, and industry and increasing every year the development process have oneself of industry organization, have considerable cohesion, so can take China leather, synthetic leather, enterprises, including related industry organization together, develop into a considerable strength of the industry.
Following the PVC leather, PU synthetic substrate after through science and technology experts 30 years of intensive research and development, as the ideal substitute for natural leather, won the breakthrough technology progress.
PU coating on the fabric surface first appeared in the 1950s to the market, in 1964, American dupont developed a used the PU synthetic leather upper. The Japanese company has established a set of annual 600,000 square meters production line later, after 20 years of continuous research development, PU synthetic leather whether in product quality, variety, and yield of got fast growth. Its performance getting closer to the natural leather, certain performance even more than natural leather, reached and natural leather true difficult points degree, in human daily life occupies a very important position.
Today, Japan is the largest producer of leather, coke li, emperor DongLi, clock, spun a few companies such as product basically representing international 1990s development level. The fibre and nonwoven manufacturing towards super thinning and high density change and high non-woven effect direction; Its PU manufacturing towards PU dispersed, PU water emulsion direction development, product applications from the beginning of expanding, and for shoes, bags field to the clothing, ball games, decoration and other special application domain, throughout all aspects of People's Daily life.
Artificial leather, synthetic leather, the challenge of natural leather
Natural leather because of excellent natural characteristics is widely used in the production of commodities and industrial goods, but as the world's population growth, the demand for leather human multiply, the limited number of natural leather already cannot satisfy people this kind of demand. To solve this contradiction, scientists several decades ago, it will begin to research and development artificial leather, synthetic leather, to make up for the lack of natural leather.
