The invention relates to fire resistant, electrostatic preventing, moisture permeable, anti-chemical and anti-gas composite fabric based on electro-spinning fibers for chemical protective clothing for firefighters, which sequentially comprises, from outside to inside, a fire resistant and electrostatic preventing layer, an anti-chemical isolating layer and a thermal insulating layer, wherein the fire resistant and electrostatic preventing layer is natural fire-resistant fabric or fabric after fire-resistant finish; the anti-chemical isolating layer is composed of an electro-spinning fiber film, a film base cloth and an activated carbon non-woven fabric that are sequentially arranged from outside to inside; the thermal insulating layer is composed of non-woven fabric or felt made of fire-resistant fiber; and the anti-chemical isolating layer is laminated together with the fire resistant and electrostatic preventing layer and then quilted with the thermal insulating layer. The inventive composite fabric has the advantages of good gas permeability, good electrostatic prevention, waterproof, anti-chemical, anti-gas and moisture permeability, good degradation liability, no toxicity, no pollution; and can be used for fire fighting and chemical defense, and can be used in the fields needing personal protection such as military, petroleum industry, decontamination, and dangerous chemicals.
Description
technical field [0001] The invention relates to a protective clothing composite fabric based on electrospun fibers, in particular to a fire-resistant, anti-static, moisture-permeable, anti-biochemical, and anti-virus composite fabric for fire-fighting and anti-chemical clothing based on electrospun fiber membranes, which is widely used in metallurgy , petroleum, military, hazardous chemicals, decontamination and other fields of personal protective equipment. Background technique [0002] At present, special disaster accidents such as leakage of dangerous chemicals and building fires are on the rise year by year in my country. At the same time, in order to deal with potential fire, chemical, and biological threats, the public security firefighting and the military must earnestly prepare for special disaster accidents and terrorist violence. Fire protection and chemical protection clothing is a necessary personal protective equipment for fire fighting and emergency rescue ope...
