Multifunctional protective clothing fabric

Abstract

The invention discloses a multifunctional protective clothing fabric. The fabric comprises a surface layer, a heat-insulating layer and a lining layer which are in successive bonding, wherein the surface layer comprises a polyphenylene sulfide fabric and a polytetrafluoroethylene film, and is prepared through the following steps: subjecting the polyphenylene sulfide fabric to modifying treatment with a mixed solution of a polytetrafluoroethylene emulsion, polyhexafluoropropylene, a silane coupling agent, active polypeptide, a film-forming agent and water, and subjecting the polytetrafluoroethylene film and the modified polyphenylene sulfide fabric to hot-pressing compounding; the heat-insulating layer is a spunlace non-woven fabric which is prepared from aramid fiber, polysulfonamide fiberand polytetrafluoroethylene fiber; and the lining layer is a blended plain weave fabric of aramid fiber and flame-retardant polyester fiber. The invention has the following beneficial effects: the protective clothing fabric provided by the invention has the advantages of high softness, light weight, comfortability in wearing, easy processing and seaming, excellent acid and alkali resistance, flame retardance, heat insulation, capability of better resisting flame and toxic gas, and excellent water resistance.

Description

technical field [0001] The invention relates to the technical field of clothing processing, in particular to a multifunctional protective clothing fabric. Background technique [0002] The world is paying more and more attention to fire protection, and with the development of the chemical industry in our country, the consumption of many highly dangerous chemicals in the industry is increasing day by day, and various serious accidents resulting from this have also increased. In the process of storage and transportation, due to the negligence of the staff or the deterioration of environmental conditions, accidents such as leakage are prone to occur, threatening people's lives, such as chlorine explosions in chemical plants or leakage accidents of other dangerous chemicals. First-line emergency firefighters need specific firefighting clothing to prevent the environment at the accident site from threatening human health. At the same time, working in an environment with these da...
