Description
Technical field
The utility model relates to a kind of lining, relates in particular to a kind of new coating lining.
Background technology
Waterproof Breathable coating fabric of the prior art mainly is a hydrophilic Waterproof Breathable coating fabric.The moisture permeation mechanism of hydrophilic Waterproof Breathable coating fabric is because sweat vapour contacts with fabric face, is delivered to the external world by hydrophilic radical.The greatest problem that this lining exists is exactly: the hydrophilic radical adsorbed water molecule, and make fabric become very thick and heavy, clammy, the human body dress has discomfort.By contrast, the pore type waterproof moisture permeable fabric seems more and to be fit to the degree requirement comfortable and easy to wear of human body.The pore type waterproof moisture permeable fabric, utilize micropore row aproll steam, make moisture arrange diffusing to extraneous air from temperature and the higher relatively side of humidity (inner body surface side) with being ordered about passing property, rather than by the hydrophilic radical transmission, this row mode of loosing is more discharged mode near the normal sweat of human body, is fit to the degree requirement comfortable and easy to wear of human body more.
The pore type waterproof moisture permeable fabric has two kinds at present basically, and a kind of is to be the polytetrafluoroethylene (PTFE) material of representative with Goretex, and another kind is to be polyurethane (PU) material of representative with Britain Porelle.The former is popular many years ago, but decline recently, problem in the application is that PTFE film itself is difficult for fitting, and using the weakness of rerum natura to be: the most micropores of PTFE are a kind of synusia shape micropores, therefore cause water-wash resistance own poor, wash the various rerum naturas that just lose original material for 3～5 times basically.With Britain Porelle is the microporous membrane of the pure polyurethane material of representative, the institute that has microcellular structure on the one hand has superiority, the weakness that does not have simultaneously PTFE above-mentioned again, in the actual use test, wearer's feedback feeling is very dry and comfortable comfortable, should represent this trend of new round material in the industry, the high rerum naturas requirement that therefore got more and more at present, the outdoor brand merchant who especially pays close attention to the actual comfort of consumer adopts.Its principal character is that sweat, the sweat steam raising that can quickly human body be formed are discharged, and avoids condensing in clothes, keep dry and comfortable, the warm sensation of user, but this material is used for garment material, and it makes complexity of processing technology, and cost is higher.
More than two kinds of composites, the external product cost is about 20 dollars every meter, utilize dry coating technology to make the pore type waterproof moisture permeating fabric and have stronger cost advantage, every meter about 20 yuans, descend significantly than the product cost of external equal performance.The present domestic correlative study that utilizes dry coating technology to make the pore type waterproof moisture permeating fabric that has, but all do not have to produce in enormous quantities, though problem is that the existing micro porous coating product of this technology water vapour permeability is good, but resistance to hydrostatic pressure and water-wash resistance are poor, if can have breakthrough on the balance of poisture-penetrability and wash durability, this lining will have vast market prospect.
Chinese patent CN2526168Y provides a kind of waterproof moisture permeating fabric, and it comprises fiber fabric layer and microporous film layers, and the one side that it is characterized in that microporous teflon membran applies mainly by what polyurethane was formed and refuses oily hydrophilic coating.This fabric is compared with existing polytetrafluoroethylporous porous membrane fabric, has water-fast effect of washing dry-cleaning and permanent Waterproof Breathable.But this fabric water pressure resistance performance is not high, and adopts polytetrafluoroethylene film and fabric compound, and technology is complexity.
In view of this, special the utility model that proposes.
The utility model content
The purpose of this utility model is to provide a kind of new coating lining, and the existing better saturating wet steam performance of this lining is the higher hydraulic pressure of ability again, and is comfortable and easy to wear.
For realizing the purpose of this utility model, adopt following technical scheme:
A kind of new coating lining comprises bearing layer, is coated on the watertight composition on the bearing layer and is coated on microporous layers on the watertight composition that described coating fabric comprises that also one is coated on the overcoat on the microporous layers, and this overcoat is the wear-resistant coating with microcellular structure.
