Manufacture of high strength low extension polyester filament manufacturing method of high strength and low interest Shandong extension polyester filament yarn Our company specializes in the production of geotextiles, we hope that the new and old customers and friends can learn more about our products, so that the use of real help. The following experts for you to resolve our source material: high-strength polyester filament some of the manufacturing method, considered the main indicators of the preparation of high-strength low-latency control polyester filament material is sliced ??molecular weight and its distribution, diethylene glycol content and moisture content. Prepared by melt polycondensation of a certain molecular weight prepolymer, and then solid phase polymerization system and then a high molecular weight polyester, is more common and practical method. Producing high-strength low-latency polyester filament common process is a high molecular weight polyester using slow cooling after shaping to reduce the original pre-oriented yarn to multi-stage stretching as far as possible to improve the draw ratio, spinning and drawing can be intermittent, or may be a step France staple geotextile manufacturers purchase, but one step requires a certain temperature and adequate residence time and think incremental stretching method is to create an ideal high-strength fiber stretching method, using spin-forming speed can be intense heat improve the structural stability of polyester filament, making it more suitable for industrial use. More specifications geotextile, more reasonable price, all in Shandong Sheng Kui Currently, the world of polyester and polypropylene geotextile as the main raw material, the annual consumption of more than one billion square meters in short silk geotextile factory outlets, about 40 tons, of which the amount of polyester and polypropylene geotextile 50-50. US annual consumption of which 8 to 10 million tons, accounting for 83% polyester geotextiles, polypropylene geotextile 14%; Japan accounted for 21% polyester geotextiles, polypropylene geotextile accounted for 73% of the world is expected geotextile market demand The average growth rate of 9%.
