Description

Washing fastness breathable fabric
Technical field
The present invention relates to a kind of washing fastness breathable fabric, belong to weaving face fabric technical field.
Background technology
Coating fabric only possesses simple function at present, can not meet human body (high humidity in relative adverse circumstances simultaneously, atmosphere draught-free, as mining industry, oil well operation personnel) long-term operation, be unfavorable for special work post (traffic police, patrol police, road surface cleanup crew) in daily operation process because fabric visibility is inadequate, protection and the protection that cannot produce human body inherently safe, be unfavorable for carrying out in particular cases (as fire-fighting fire extinguishing, accidental explosion, during burning) fabric do not possess anti-flammability, and thereby fabric only possesses combustion-supporting property generation to human body calcination, the situations such as burn
Particular problem:
1, common coating fabric only possesses simple function (as only possessed high hydraulic pressure or only possessing poisture-penetrability etc.)
2, common coating fabric does not possess long-term taking, and at outside destroy or in washing process, relevant crucial physical index is easily lost (under hydrostatic pressing, reduce very fast, flame retardant effect is lost);
3, thereby common coating fabric can not meet the visuality lifting special work post personal security that promotes human body.
4, the anti-flammability of common coating fabric is generally used for house and spins series products, and for fire-retardant being difficult to resolve of clothing, certainly feel is partially hard, the weakness that flame retardant effect is long-acting not.
5, shortcoming a little less than common coating inflaming retarding fabric, peel strength not good at the warp resistance of cold-resistant glue face below-30 ℃.
6, common coating inflaming retarding fabric cannot possess good anti-flammability simultaneously, effectively smoke-suppressing and prevent that molten situation from producing.
7, fireproof powder, flame retardant oil are difficult to effectively dissolve in polyurethane resin, easily produce powder and assemble, and cannot carry out scraper for coating, produce the unbalanced situation of anti-flammability.
8, the plain edition fireproof powder flame retardant oil on market not good aspect the feature of environmental protection, do not meet oeko-Tex standard 100, the environmental requirement of REACH bill.
Summary of the invention
