Our commonly used polyester with its superior characteristics, the production process is simple, easy access to raw materials, etc., after long-term development has become one of the world's four major chemical fiber. And polypropylene high-strength silk fiber in China to the eighties of last century began to develop, and in the eighties R & D success of high melt index fiber polypropylene resin, after continuous research and development and improvement, and has been able to keep pace with the polyester.
The relative density of polypropylene high strength silk fibers is 0.91g / m³, 40% lighter than cotton, 34% lighter than polyester, is the smallest fiber in the known density, and is the only one can float on the surface of the fiber. And because the thermal conduction rate of polypropylene itself is very low, so to maintain the maximum temperature, creating a polypropylene with raw materials as the warm series of fabric. In the 21st century, polypropylene will be more than polyester into the world's second chemical fiber. Which in turn the development of polypropylene fine filament filament the most impressive.
At present, the polypropylene fabric has been more and more people's pro-Lai, especially in recent years due to the gradual reduction of world cotton production, cotton fabric prices also will rise, and because of polypropylene is in addition to cotton, linen, silk and other fabrics Personal fiber, its breathable, light, warm, one-way wet, deodorant and other characteristics of sterilization, polypropylene silk fabric sought after also understandable.
Polypropylene high-strength silk raw materials - polypropylene, but also because of China's industrial development, followed by mining processing capacity has also greatly improved. At present, China's polypropylene production and processing has exceeded 100 tons, accounting for only one percent of all chemical fiber ratio, while the US polypropylene production accounted for 34% of the proportion of most of the West in 27% up and down. It seems that China's polypropylene market prospects are very open, there is a lot of room for development. The international price of polypropylene high-strength wire has been as high as 20,000 US dollars / ton, due to the excellent characteristics of high-strength polypropylene fiber has become the world's mining hot spots. In foreign countries has formed a complete set of polypropylene fiber research and development production line, although the overall level in China is low, the production line is not complete, but believe that China's polypropylene market in the future will be flourishing.
