Abstract

The invention relates to a heat-insulating chemical filament. The heat-insulating chemical filament comprises, by weight, 17-22 parts of natural ceiba fibers, 5-8 parts of electric mountain flour, 6-10 parts of rutile powder, 2-4 parts of vinylphosphonic acid, 12-18 parts of silks, 10-15 parts of nano silicon oxide, 12-15 parts of polyimide powder, 13-20 parts of wool, 9-14 parts of zinc oxide and 14-19 parts of polylactic acid fibers. The obtained heat-insulating chemical filament has the advantages that the chemical filament produced according to the special raw material formula has circular cross section and stable chemical and physical performance, the heat insulation temperature is larger than or equal to 250 DEG C, the water solution temperature is 80-90 DEG C, the breaking strength is larger than or equal to 3.5cN / dtex, and the monofilament fineness is 2-10dtex; the manufacture process is simple and beneficial to large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of chemical fiber materials, in particular to a heat-resistant chemical fiber filament and a preparation method thereof. Background technique [0002] Chemical fibers are fibers with textile properties that are made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. A chemical fiber that can basically maintain its original physical and mechanical properties after being subjected to high temperature (for example, above 200°C) for a long time. Special fibers that do not soften at high temperatures and can still maintain general mechanical properties are also called heat-resistant fibers. At present, there are few chemical fiber filaments that can withstand 250°C on the market. Contents of the invention [0003] The object of the present invention is to provide a heat-resistant chemical fiber yarn. [0004] Anoth...
