Since 1957, with the technological advancement of spinning grade polypropylene and spinning technology, the output of high-strength polypropylene yarn in 1996 exceeded 5 million tons, accounting for 11.5% of synthetic fiber, which has received more and more attention in the development of chemical fiber in the world. .
The shape of the High-strength polyester fiber is straight and smooth, the cross section is round, and the texture is light. Its density is only 0.91g/cm3, which is the lightest density among common chemical fibers, so the same weight of polypropylene high-strength yarn can be obtained by other fibers. Higher coverage area.
High-strength polyester fiber has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, high-strength polypropylene filament has good resistance to acid and alkali, so it is suitable for use as filter material and packaging material.
High-strength polyester fiber has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing.
Jiangsu Silk Wire Fiber Co., Ltd. is a professional company engaged in the research and development of all kinds of engineering fibers, High-strength polyester fiber, high-strength double-twist polypropylene filament, and integrated line management. The main indicators of all products are tested by national authorities and are in the current international. Leading level, the products sell well in China and are exported to overseas.
