Abstract
Discloses is a waterproof moisture permeating leather for manufacturing garments, shoes and caps. The surface of a bottom layer 4 is coated with a micropore layer 3 which is distributed with humidity permeating eyelets 2, and the surface of the micropore layer 3 is connected with a moisture guiding layer 1, which ensures that humidity molecules generated when human body sweats can successfully pass through the bottom layer and the micropore layer, and are adsorbed on the inner surface of the moisture guiding layer. The moisture guiding layer comprises hydrophilic groups which is very easily to combine with water molecules, the hydrophilic groups can conduct and discharge the humidity molecules from high temperature layer (inner surface of the moisture guiding layer near human body) to low temperature layer ( arranged on the outer surface of the moisture guiding layer in external temperature environment). Since the external environmental temperature of the moisture guiding layer is lower than internal temperature of the moisture guiding layer near human body, water (rain, snow) on the outer surface of the moisture guiding layer can not permeate into the inner surface of the moisture guiding layer, thereby achieving effect of water resisting and moisture permeating. Through testing, moisture permeability rate is above 1800g/ mm<2> 24h, and the waterproof moisture permeating leather is still soft 40 degrees below zero, without generating cracks after repeatedly being bended and folded 50 thousand times.
Description
Technical field: the utility model relates to synthetic leather fabric; Be specifically related to people and manufacture the Water-proof artificial leather of clothes, shoes and hats.
Background technology: people manufacture clothes, the used synthetic leather lining of shoes and hats in the prior art, are to apply to be connected with PVC or polyamine fat material formation on nonwoven surface.Though play certain anti-chill, the effect of rain and snow, but have the following disadvantages: the one, be coated on the not saturating moisture of synthetic leather surface layer on the nonwoven surface, people dress the clothes that adopt synthetic leather fabric to manufacture in life and work, when shoes and hats are perspired, the wet gas that produces can't be discharged to extraneous atmospheric environment by the synthetic leather surface layer, makes people's body and mind very uncomfortable; The 2nd, manufacture the synthetic leather fabric of clothes, shoes and hats and dress the jackknifing breakage of easily hardening at cold district, shortened service life.
Summary of the invention: technical problem to be solved in the utility model, the one, the not saturating moisture of the clothes that synthetic leather fabric is manufactured, shoes and hats causes people to be worn on when body is perspired and can't discharge, and body and mind is very uncomfortable; The 2nd, manufacture the synthetic leather fabric of clothes, shoes and hats, dress the jackknifing breakage of easily hardening at cold district, shortened service life.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked: this Water-proof artificial leather is to be coated with the microporous layers that is covered with the moisture aperture on bottom surface; On described microporous layers surface, be fitted with wetness-guiding layer again.
The utility model adopts technique scheme, on the bottom surface that constitutes at the strong superfine fibre of bonding strength height, flexibility and gas permeability, be coated with the microporous layers that is covered with the moisture aperture, the wet gas molecule that produces when human body is perspired, pass through from bottom and microporous layers smoothly, be adsorbed on the wetness-guiding layer inner surface that is connected on the microporous layers; Described wetness-guiding layer material contains very easily the hydrophilic radical with water molecules, can be with the wet gas molecule from high-temperature aspect (near the wetness-guiding layer inner surface of human body skin), conduct discharge to low temperature aspect (the wetness-guiding layer outer surface that directly contact with external temperature environment).Because the wetness-guiding layer ambient temperature is lower than the temperature of its inboard near human body skin, makes the water (rain, snow) that places on the wetness-guiding layer outer surface, then can't reach the effect of Waterproof Breathable by export-oriented wetness-guiding layer inner surface conduction.The clothes that the employing Water-proof artificial leather is manufactured, shoes and hats are through testing: moisture permeability is at 1800g/m
2More than the 24h, the wet gas molecule that produces that guaranteed to perspire in people's body running or the motion is in time discharged.Anti-high and cold, the bend resistance of Water-proof artificial leather ,-40 ℃ of temperature still softness as before, bend repeatedly 50,000 times flawless, improved service life.
Description of drawings: Fig. 1 has the schematic perspective view of part section for the utility model.
The specific embodiment: shown in Figure 1.Bottom 4 adopts good permeability usually, bonding strength is high and the nylon ultrafine fiber of soft bend resistance constitutes; Be coated with the microporous layers 3 that polyamic acid ammoniacum (PAU) resin film constitutes by the wet type processing technology on bottom 4 surfaces, described microporous layers 3 surfaces are gone up nature and have been covered with saturating moisture aperture 2; Usually the thickness of microporous layers 3 is at 0.05mm～0.07mm; Saturating moisture aperture 2 diameters are typically chosen in the size between water vapour molecule diameter and hydrone diameter, are generally in 0.1 μ～4 μ scopes; On microporous layers 3 surfaces, adopt the transfer lamination combination process to be fitted with wetness-guiding layer 1 again.Described wetness-guiding layer 1 has hydrophilicly leads moist anti-again by force high and coldly, and surface abrasion resistance is difficult for the characteristics of impaired scuffing, strengthened the aesthetic feeling decorative effect on Water-proof artificial leather surface.
