MULTILAYER STRUCTURED SPUN YARN, PROCESS FOR PRODUCING THE SAME, AND, FABRICATED FROM THE YARN, HEAT-RESISTANT FABRIC AND HEAT-RESISTANT PROTECTIVE SUIT

摘要

A kind of multilayer structured spun yarn (C groups) includes core fibre (one), is covered on surrounding lid, fiber B. The usage amount of core (one) is 20 to 50 weight % while covering the usage amount of fiber (B groups) to be 50 to 80 weight %. Core (one) is that twisting stretches crush cutting bamboo section pattern yarn by the form to aramid fiber. The fiber (component B) of lid includes flame-retardant acrylic fibre, the fiber or meta-aramid fiber of polyetherimide. Stretching crush cutting bamboo section pattern yarn has the identical yarn with the multilayered structure of that of a torsional direction. The multilayered structure (C groups) of the yarn of twisting is 1.2 to 1.6 times of stretching crush cutting bamboo section pattern yarn. The heat-resistant fabric uses above-mentioned multilayer structured spun yarn. The protective garment is the protective garment for having used above-mentioned heat resistance cloth and silk.
