Problems solved by technology

[0002] General chemical fiber filter material does not have antistatic function, and it is easy to generate static electricity due to friction during use.
The flue gas and dust produced by some processes in cement, coal-fired power plants, iron and steel smelting, and chemical industries have the characteristics of high temperature, flammability and explosion. When the concentration of smoke and dust reaches a certain limit, sparks generated by electrostatic discharge will cause Fire, even explosion accidents, some base fabrics have low tensile strength and deformation resistance, which greatly reduces the service life of base fabrics, and the existing base fabrics have relatively single functions, and some base fabrics do not have high temperature resistance. It is easy to burn when used in high-temperature occasions such as firefighting, and has poor fireproof performance; some carpet base fabrics have low friction with the surrounding medium, and are prone to relative sliding, posing a threat to personal safety

Abstract

The invention discloses fireproof and flame retardant aramid fiber filter material base cloth. The fireproof and flame retardant aramid fiber filter material base cloth comprises a base cloth body; aplurality of uniformly distributed transverse wefts are sewed in the base cloth body; a plurality of uniformly distributed vertical warps are sewed in the base cloth body; the connecting parts of theplurality of wefts and the plurality of warps are connected with each other through connecting pieces; primary tensile fiber filaments and secondary tensile fiber filaments are sewed between the adjacent connecting pieces through a needle and a thread; the primary tensile fiber filaments and the secondary tensile fiber filaments are arranged in a crossed manner; a aramid fiber mesh layer is bondedon the upper surface of the base cloth body through a bonding agent. As stainless steel fiber conductive yarns are additionally arranged, a transferring passage is available for static electricity torealize an anti-static effect; in addition, anaphylaxis of a user, which is caused because a fabric is uneasy to adsorb dust or pollen due to frictional electrification, is avoided; in addition, an anti-static fiber possesses excellent washing fastness, bending resistance and wear resistance; therefore, the anti-static fabric is easy to take care and is durable.

Description

technical field [0001] The invention relates to the field of aramid fiber filter material, in particular to a fire-resistant and flame-retardant aramid fiber filter material base cloth. Background technique [0002] General chemical fiber filter material does not have antistatic function, and it is easy to generate static electricity due to friction during use. The flue gas and dust produced by some processes in cement, coal-fired power plants, iron and steel smelting, and chemical industries have the characteristics of high temperature, flammability and explosion. When the concentration of smoke and dust reaches a certain limit, sparks generated by electrostatic discharge will cause Fire, even explosion accidents, some base fabrics have low tensile strength and deformation resistance, which greatly reduces the service life of base fabrics, and the existing base fabrics have relatively single functions, and some base fabrics do not have high temperature resistance. When use...
