Description
Technical field
The invention belongs to individual protection clothes fabric field, what be specifically related to is a kind of individual protection clothes fabric that is applicable to the normal property sent out disaster and preparation method thereof.
Background technology
The kind of existing individual protection clothes is a lot, puts into different categories, and the purposes difference, fabric is different, and different occasions need be dressed different protective clothings.For a long time, people improve a certain of protective garment fabric or two kinds of barrier propterties up and down foot the time, and obtained gratifying achievement, but to being applicable to the research insufficient investment of the normal property sent out disaster prevention clothes fabric, therefore, up to the present, also do not have a kind of can satisfy simultaneously can be fire-retardant, gas defence, the individual protection clothes that have both light use, good mechanical performance again come out.
The fabric of individual protection clothes is basic materials of protective clothing.Though the biochemical toxic agent of obstruct of the isolated fully type protective fabric energy long period that du pont company is produced has higher heat stress effect, and anti-stab poor-performing; The LANX series armored fabric fabric of the Natick of U.S. army research and development engineering center development has good adsorption, durability, venting capability and comfortableness, also can provide fire resistance, but its production cost is too high; People such as Chinese science man Cong Ji letter are skeleton with 527 bright and beautiful silks, fluorubber and active carbon, No. 3 auxiliary material such as vulcanizing agent are developed into the latex bottom sizing, successfully made the ventilating type protection material that is used for the propellant system, fire resistance has also obtained further raising, but cost is still very high; People such as Liu Jiangge directly mix flame retardant activity charcoal fabric and are woven into cloth in the polyacryl-nitrile spinning fluid, have good flame performance and gas defence effect, to the infiltration of biochemical toxic agent have the long period, barrier widely, and have preferably mechanical properties such as anti tear, wear-resistant and anti-puncture, but the ventilating performance of fabric is relatively poor relatively.
The vapor-permeable type protective garment fabric absorbs the toxic agent composition by activated carbon constituents, the guarantee that is perfectly safe is provided for human body, even the long period dress does not have very high human body heat stress effect yet, but the adsorption capacity and the snugness of fit that improve its adsorption layer are still focus and the difficult point that the designing technique aspect will solve; The rubber coated fabrics material of existing coated fabric class protective garment fabric can have the anti-ability of fabulous resistance to toxicity liquid, gas componant, but fire resistance is relatively poor.
