High-temperature resistant cutting preventing composite yarn and application thereof

Abstract

The invention relates to a high-temperature resistant cutting preventing composite yarn and the application of the high-temperature resistant cutting preventing composite yarn, belonging to the technical field of special yarn. The high-temperature resistant cutting preventing composite yarn comprises a central fiber and a coated fiber, wherein the central fiber is used as an inner core, and the coated fiber is formed by twisting, winded with the central fiber and coated outside the central fiber. The high-temperature resistant cutting preventing composite yarn is characterized in that the central fiber is the chemical filament and accounts for 30-70% by mass of the composite yarn, the coated fiber is the short aramid fiber 1414 and accounts for 70-30% by mass of the composite yarn. The high-temperature resistant cutting preventing composite yarn integrates the outstanding high-temperature resistance and fire resistance of the short aramid fiber 1414 and the advantage of excellent cutting-preventing performance of the chemical filament, and the fabric made of the high-temperature resistant cutting preventing composite yarn by processing can be used in the high-temperate and sharp work environment. The high-temperature resistant cutting preventing composite yarn is safe and durable.

Description

technical field [0001] The invention belongs to the technical field of special yarns, and in particular relates to a high-temperature-resistant and cut-resistant composite yarn, and also relates to the application of the yarn. Background technique [0002] At present, protective products made of asbestos fiber-based composite yarns are generally used in typical high-temperature occasions such as steel manufacturing industry and sharp working conditions (working environment) such as glass product manufacturing industry. Although asbestos has the advantages of good high temperature resistance, friction resistance, low price, light specific gravity, low thermal conductivity (0.198-0.244W〈m·k〉) and low electrical conductivity, however, asbestos is carcinogenic to the human body As well as polluting the environment, the production and use of asbestos products, including protective equipment, is increasingly restricted, and even banned in many economically developed countries and ...
