Abstract
The utility model discloses comfortable waterproof moisture permeable leather, which not only can be rainproof and snow-proof, but also can discharge sweat of a user timely, is high in comfort degree and has a special function. The waterproof moisture permeable leather comprises a fabric layer and a polyurethane film layer coated on the surface of the fabric layer; moisture permeable micropores are uniformly formed in the polyurethane film layer; a polytetrafluoroethylene waterproof moisture permeable layer is also coated on the surface, which is far away from an superfine fiber fabric layer, of the polyurethane film layer; and breathing micropores are uniformly formed in the polytetrafluoroethylene waterproof moisture permeable layer, the diameters of the breathing micropores are proper, so that water vapor in the form of single molecules can be smoothly discharged outwards through capillary ducts among fibers, and droplets cannot permeate through gaps in fabrics.
Description
Technical field
The utility model relates to a kind of lining, especially relates to a kind of Waterproof Breathable leather.
Background technology
Along with expanding economy and living standards of the people improve constantly, human beings'health consciousness is more and more stronger, and is also increasingly high to the requirement of artificial leather; Existing artificial leather adopts terylene or other coated with polyurethane on base cloth to process; Often there is contradiction in this artificial leather on ventilative and water-proof function property, promptly during good permeability, water pressure resistance is relatively poor; When water pressure resistance was high, gas permeability was relatively poor.Such artificial leather is processed clothes or shoes, and often function is relatively poor, can not realize the unification of comfortableness and specific functionality.
Summary of the invention
Therefore, to above-mentioned problem, the utility model provides a kind of comfortable Waterproof Breathable leather: both can soak by rain and snow, the sweat that can in time give out health again emits, and has realized the unification of comfortableness and specific functionality.
For achieving the above object; The utility model is realized through following technical scheme: a kind of Waterproof Breathable leather; Comprise tissue layer and coat the thin polyurethane rete of fabric layer surface; Be evenly equipped with wet micropore on the said thin polyurethane rete, said thin polyurethane rete also is coated with one deck polytetrafluoroethylwaterproof waterproof moisture permeating layer away from the surface of tissue layer, is evenly equipped with ventilative micropore on the said polytetrafluoroethylwaterproof waterproof moisture permeating layer.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: what human body gave out is the water vapour of unimolecule state, and sleet then is the liquid water droplets of coherent condition, and their volume size differs greatly.In addition; The water of liquid has a kind of capillary characteristic that is called as; The characteristic of just gathering own vol, the Waterproof Breathable leather is exactly a surface tension characteristics of utilizing water, on fabric, is coated with the capillary immersion coating of enhancing lining of one deck PTFE polytetrafluoroethylwaterproof waterproof moisture permeating thin layer; The globule is tightened up as far as possible and can not scatter, soak into lining surface, thereby can't see through the structural space of lining.Simultaneously, this PTFE polytetrafluorethylecoatings coatings is again porous, and the water vapour of unimolecule state can see through interfibrous capillary canal smoothly and be dispersed into the lining surface.
The Waterproof Breathable leather refers to that promptly water does not see through cladding under certain pressure, and the sweat that human body distributes can reach the external world through cladding with the form of steam, and sweat can not assembled on human body skin surface or cladding in condensation, thereby reaches comfortable purpose.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment:
With reference to figure 1; Present embodiment discloses a kind of Waterproof Breathable leather; Comprise superfine fibre tissue layer 1 and coat the thin polyurethane rete 2 on superfine fibre tissue layer 1 surface; Be evenly equipped with wet micropore 21 on the said thin polyurethane rete 2; Said polyamine ammonia thin layer 2 also is coated with one deck polytetrafluoroethylwaterproof waterproof moisture permeating layer 3 away from the surface of superfine fibre tissue layer 1, is evenly equipped with ventilative micropore on the said polytetrafluoroethylwaterproof waterproof moisture permeating layer 3, and the diameter of said ventilative micropore is: the water vapour of unimolecule state can see through interfibrous capillary canal smoothly and discharge; Thereby the globule can't see through the structural space of lining.Usually the diameter range of air-vent is: 0.1-0.4um.
Said PTFE polytetrafluoroethylwaterproof waterproof moisture permeating layer serves as basic with the one-tenth pore property of polytetrafluoroethylplastic plastic resin, and the microporous membrane that adopts bidirectional extending method to produce has waterproof, passes through wet characteristics.Water resistance is good, and the micropore size of PTFE polytetrafluoroethylwaterproof waterproof moisture permeating layer is the 1/5000-1/20000 of drop diameter, even therefore minimum raindrop can not pass through; The PTFE surface energy is low, and water droplet can not be sprawled layer by layer at said PTFE Waterproof Breathable, stops water droplet to see through.Water vapour permeability is good, and the porosity of PTFE Waterproof Breathable layer is up to 80%, and average pore size is 0.2um, and micropore size is greater than 700 times of stream molecule, and stream molecule can freely pass through.
The Waterproof Breathable leather refers to that promptly water does not see through cladding under certain pressure, and the sweat that human body distributes can reach the external world through cladding with the form of steam, and sweat can not assembled on human body skin surface or cladding in condensation, thereby reaches comfortable purpose.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
