China Drying Net is jointly developed by Yizheng Chemical Fiber, Yanshan Petrochemical, Nanhua Group Research Institute and China Textile Research Institute, and is responsible for the development of para-aramid industrial heat-setting process, high-performance polyethylene staple fiber processing and spinning technology development, and dry spinning. The research projects on ultrahigh molecular weight polyethylene and fiber processing and quality indicators for silk and high molecular weight polyethylene materials for melt spinning have recently passed the appraisal organized by the Ministry of Science and Technology of China Petrochemical Corporation.
These four technologies belong to the field of high-performance fibers, and the research results have been verified by industrial applications. Experts in the field of identification believe that the para-aramid industrialized heat-setting process development project has developed and designed a high-temperature heat setting device that satisfies the process conditions, developed a heat-setting complete set of technology, and the technology has reached the international advanced level; high-performance polyethylene staple fiber processing and spinning The technical development project has developed high-performance polyethylene short fiber crimping equipment, developed high-performance polyethylene staple fiber spinning technology, short fiber pure spinning and blended yarn series products, technologies and products are the first in the country; dry spinning Silk used ultra-high molecular weight polyethylene and fiber processing process and quality index research projects to establish a quality control index system for dry spinning ultra-high molecular weight polyethylene fiber resin, and built a super-high molecular weight polyethylene fiber dry Method for spinning simulation and direct evaluation of spinnability. The results of the study are instructive for the development of resins and fiber preparation technologies. The high-molecular-weight polyethylene special materials for melt spinning have developed special equipment for melt spinning and developed high Relative molecular mass polyethylene melt spinning complete sets of technology, products can meet civilian fiber Product performance requirements.
