Abstract
The utility model relates to waterproof heat-preservation leather which is mainly formed by bonding and compounding an ultra filament skin base, a heat-insulating resin layer and a wet-method polyurethane coating, wherein a water repelling layer is arranged below the ultra filament skin base; the ultra filament skin base adopts sea-island type ultrafine fibers; the heat-insulating resin layer contains heat-insulating micro-particles; the heat-insulating micro-particles are diatom microparticles or diatomite microparticles or asbestos microparticles; sea island components of the sea-island type ultrafine fibers can be dissolved and only island components can be left to form irregular micropores which are invisible to naked eyes, so that the ventilation of the ultra filament skin base is guaranteed, the heat-insulating microparticles in the heat-insulating resin layer can provide the very good heat-preservation effect, and foaming resin has the very good moisture penetrability and gas permeability.
Description
Technical field
The utility model relates to leather, and what especially relate to is a kind of thermal insulating and water-proof leather.
Background technology
Southern winter is based on rainy weather, so shoes must accomplish that the tool waterproof is warming again.At present, leather shoes water resistance on the market is better, be adapted at the rainy day dress, but its thermal property is often not enough.And the cotton-padded shoes water resistance is not enough, is being spattered with water easily in the rain, is difficult for dry its thermal property that influences.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of leather of thermal insulating and water-proof is provided.
For achieving the above object, technical solution of the present utility model is: a kind of thermal insulating and water-proof leather, mainly be composited by micro fiber leather base, adiabatic resin bed and wet polyurethane coating bonding, and micro fiber leather base below is provided with one deck water repellent layer.
What preferably, described micro fiber leather base adopted is sea-island composite fiber.
Preferential, described heat insulation layer contains adiabatic particulate, and wherein adiabatic particulate is diatom particulate or bergmeal particle or asbestos particles.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: what the micro fiber leather base adopted is sea-island composite fiber, and the sea component in the sea-island composite fiber can dissolve, and stays island component, form the sightless micropore of irregular naked eyes, thereby guaranteed the gas permeability of footwear leather.When carrying out wet processing, water repellent layer can make the micro fiber leather base can Yin Wendu rise and sharply expansion, allows liquid such as water flow in micro fiber leather base and adiabatic resin bed, has avoided the generation of " bubble ", guaranteed the quality of footwear leather, and water repellent layer has improved the water resistance of footwear leather again.Adiabatic resin bed adopts Foamex, wherein is distributed with adiabatic particulate good warming effect is provided, and foamed resin layer has good moisture-penetrable ventilated property, has strengthened the gas permeability of footwear leather.
Description of drawings
Fig. 1 is structure cutaway view of the present utility model.
(identify among the figure: 1, water repellent layer; 2, micro fiber leather base; 3, adiabatic resin bed; 4, wet polyurethane coating)
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of thermal insulating and water-proof leather of the present utility model is tied successively by micro fiber leather base 2, adiabatic resin bed 3 and wet polyurethane coating 4 and to be composited, and there is one deck water repellent layer 1 micro fiber leather base 2 belows.Preferably, described micro fiber leather base 2 adopts sea-island composite fiber, sea-island composite fiber manufactures nonwoven fabric, in making finishing processes, the island of sea-island composite fiber becomes branch's dissolving, only stays island component, thereby forms the sightless micropore of irregular naked eyes, guaranteed the gas permeability of micro fiber leather base 2 at the back side of micro fiber leather base 2 roller coat Organic fluoride or organosilicon dryingagent solution, oven dry forms water repellent layer 1.Described adiabatic resin bed 3 contains adiabatic particulate, and wherein adiabatic particulate is diatom particulate or bergmeal particle or asbestos particles, and good warming effect can be provided, and Foamex has good moisture-penetrable ventilated property.In carrying out the wet polyurethane coating procedure, water repellent layer 1 reduces the surface tension of micro fiber leather base 2, make shipwreck to enter from micro fiber leather base 1 among water repellent layer 1 and the micro fiber leather base 2, allow liquid such as water in polyurethane coating 4 and adiabatic resin bed 3, carry out, but because adiabatic resin bed 3 poisture-penetrabilitys are good, avoided the generation of " bubble ", guaranteed the quality of footwear leather, and water repellent layer can improve the water resistance of footwear leather again.
Above-described, only be a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
Claims (2)
1. thermal insulating and water-proof leather, mainly being bondd successively by micro fiber leather base (2), adiabatic resin bed (3), wet polyurethane coating (4) is composited, and it is characterized in that: described micro fiber leather base (2) below is provided with one deck water repellent layer (1).
2. according to the described thermal insulating and water-proof leather of claim 1, it is characterized in that: described micro fiber leather base (2) adopts sea-island composite fiber.
