At present, high-performance fibers such as carbon fiber T300, meta-aramid, aramid, ultra-high molecular weight polyethylene, polyphenylene sulfide and basalt have achieved industrialization breakthroughs, and the functionalization and differentiation of chemical fiber products have been significantly improved.
Fine denier and superfine fibers, special-shaped fibers, high moisture conductivity polyester fibers, "super-imitation cotton" polyester fibers and other key technologies have made breakthroughs and achieved industrialization; bio-based fibers have made new developments.
The bio-based fiber using renewable and degradable bamboo pulp and hemp stalk pulp as raw materials realizes industrialized production, and the solvent-based cellulose fiber breaks through the key technology of thousand-ton quasi-industrialization.
A breakthrough has been made in the key technology of jute fiber refinement and the industrial application of refined jute has been realized; the silkworm genome framework has been completed in response to the need for genetic improvement of silk quality and processing characteristics, and a breakthrough in the key technology of natural colored mulberry silk; research on high-yield and high-quality genetically modified cotton A major breakthrough has been achieved, which can greatly increase cotton production and significantly improve the fineness of cotton fibers.
The industry currently has insufficient research and development of materials such as carbon fiber, aramid and ultra-high molecular weight polyethylene fiber, and the key technology and equipment have not been broken through, and it is difficult to reach the industrial scale; the import dependency of para-aramid is more than 95%, and the import dependency of carbon fiber is more than 80%. ; High value-added new functional fibers need to be expanded and improved, and the proportion of functionalized and differentiated fibers is still low; the chemical fiber industry’s dependence on fossil resources has exceeded the warning line, and the research on non-petroleum-based new bio-based fibers is basically in In the tracking phase, the ones that have been put into production have problems such as scattered production capacity, low technology integration, relatively backward equipment, and unbalanced raw material system.
