Description
Technical field
The utility model belongs to Water-proof breathable fabric technical field, is specifically related to a kind of Water-proof breathable fabric production equipment based on nanofiber accumulation body.
Background technology
The macromolecule waterproof ventilative material that current permeable membrane type Water-proof breathable fabric uses mainly contains two kinds: one is the micro-porous membrane of polyurethane, and another kind is eptfe film.Polyurethane micro-porous film forming method can be divided into dry-press process and wet moulding, and wherein the water pressure resistance of dry-press process polyurethane micro-porous film reaches as high as 15000mmH
2o, vapor transfer rate can reach 10000g/m
2/ 24h, but there is no gas permeability, wherein with the PU micro-porous film of Bo Weier company of Britain for representative.The micro-porous membrane water pressure resistance of wet moulding polyurethane reaches as high as 10000mmH
2o, vapor transfer rate can reach 10000g/m
2/ 24h, possesses a small amount of gas permeability, is about 0.01 ~ 0.1CFM.
Eptfe film is the only selection of producing high-end Water-proof breathable fabric in current worldwide.Eptfe film mainly utilizes PTFE film to produce microcellular structure under four-way drawing force, thus reaches the effect of waterproof and breathable, and water pressure resistance maintains 10000mmH
2while O, vapor transfer rate can reach 10000g/m
2/ 24h, gas permeability can also reach 2CFM simultaneously; In order to keep the microcellular structure of polytetrafluoroethylene film not to be destroyed in dress and washing process, usual way is the polyurethane film that compound one deck is very thin on eptfe film, and this pair of maximum water pressure resistance of component film can reach 20000mmH
2more than O, vapor transfer rate can also reach 10000g/m
2/ 24h, but no longer there is gas permeability, the Ge Er company being represented as the U.S. in this technical field.
The polyurethane micro-porous film of dry-press process does not possess any gas permeability, no longer meets the requirement of modern outdoor clothes for snugness of fit; Although wet moulding polyurethane micro-porous film has a little gas permeability, micro-porous membrane of wet moulding does not possess wash durability, and after washing for several times, the Water-proof breathable fabric water pressure resistance of wet moulding micro-porous membrane compound can from mmH up to ten thousand
2o drops to 1000mmH
2about O, water resistance reduces greatly; Although the waterproof fabrics of one-component eptfe film compound has very high water pressure resistance and good permeability, also face not laundry-resistant problem, after 5 washings, water pressure resistance is from mmH up to ten thousand
2o is dropped rapidly to hundreds of mmH
2o; In order to solve the not laundry-resistant problem of eptfe film, the Ge Er company utility model method of eptfe film and polyurethane film compound use, i.e. two component polytetrafluoroethylene film, but this technology also sacrifices the permeability of eptfe film completely when solving waterproof ventilated membrane wash durability.Meanwhile, polytetrafluoroethylmaterial material is a kind of material completely non-degradable at nature, and at present because environmental issue, polytetrafluoroethylmaterial material has started to be limited to use in European Union.
