Description
Technical field
The present invention relates to clothes material technology field, and in particular to a kind of preparation method of clothes leather.
Background technology
Leather, is prepared generally by by animal skin by tanning, taw or other method.In recent years, leather
Usage amount rise year by year, be widely used on all kinds of haberdasheries, therefore the performance requirement of leather is also gradually stepped up.Skin
Leather is in wearing process, and surface easily produces or be infected with dirt, and in cleaning, wet rubbing or other aqueous leathers can be used unavoidably
Cleaning agent.In long-time, using with after repeatedly cleaning, the phenomenons such as discoloration, cracking just occur, especially in the poor leather of water proofing property
The poor leather of wet-rub resistance energy, after the cleaning of multiple wet rubbing, the lighter can cause the coating shedding of coating surface, and severe patient can make
Leather fission color；With the development of science and technology and electronics industry, various electronic apparatus applications are increasing, electromagenetic wave radiation
A kind of new social effects of pollution are had become, human body if not taking shielding measure to this kind of radiation, then holds during use
Easily very big harm is caused to healthy；Therefore need to prepare the wearable leather substance with radiation proof function；Except this it
Outside, with leather, some use PU synthetic leather to existing clothes, are typically made up of base fabric with polyurethane-coated layer, but polyurethane is high
There are splendid film forming and close molecular structure, the congenital air-locked PU faces of self-assembling formation airtight waterproof after molecule Resin crystallization
Layer, although current PU synthetic leather product surface styles and material are quite similar with natural leather, are not so good as yet with gas permeability
Natural leather, can not develop toward high-end product, natural leather can not be also replaced always again when being particularly applied to clothing item
Product usage amount.Because PU synthetic leather is without air permeable effect, the clothes being made from it can not go out human body skin hot air discharge, long
Time gets off to easily cause peculiar smell, therefore consumer still has a preference for the product using natural leather, so will result in more ecologies
Environmental disruption.
The content of the invention
The purpose of the present invention is good there is provided a kind of waterproof, radiation proof and gas permeability for problem of the prior art
The preparation method of clothes leather.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of preparation method of clothes leather, the clothes include base fabric with leather, and the surface of the base fabric is sequentially provided with base
Layer of cloth, air-permeable layer, radiation protective layer and water-repellent layer；
The preparation method comprises the following steps：
（1）Air-permeable layer is coated in scrim surfaces：By base fabric uncoiling, soaked through storing up cloth holder into immersion trough, the liquid that soaks in immersion trough is
The 10-25% DMF aqueous solution, after soaking, then by compression roller is extruded part water, and by plating, wheel removes part moisture, together
When base fabric is plated, base fabric moisture percentage is maintained at 90-95%, then on coating machine on base fabric is soaked coat air-permeable layer slurry
Material, enters back into coagulating basin into epithelium, in the process, abscess is formed in air-permeable layer, and then abundant washing, drying and shaping, are made
Air-permeable layer；
Wherein, the air-permeable layer slurry includes following raw material by weight：50-80 parts of polyurethane resin, wood powder 10-20
Part, 5-10 parts of foam improver, 0.5-1 parts of bleeding agent, 0.5-1 parts of wetting agent, 0.5-1 parts of curing agent；
（2）Radiation protective layer is prepared in ventilative layer surface：
A. in described one layer of 5-10g/m of air-permeable layer surface spraying2Film forming agent, dry；
B. base fabric process step a handled pressing 20-30s under the conditions of 2-10MPa, 40-90 DEG C, then it is equably anti-in spraying
Radiological dispersal liquid, is dried；
C. by one layer of 5-10g/m of uniformly spraying by the step b base fabrics handled2Film forming agent, dry, produce described
Radiation protective layer；
（3）Water-repellent layer is prepared on radiation protective layer surface：Waterproofing agent is coated on the radiation protective layer surface, obtains described after drying
Water-repellent layer.
Further, the base fabric is natural leather, the natural leather for livestock animals skin routinely method for leather-making
The leather of production, including chrome tanning and other process for tanning manufactured by leather；The skin of the livestock animals is ox-hide, sheep
Any of skin or pigskin.
Further, the radiation proof dispersion liquid is disperseed in deionized water by nano metal powder, and ultrasonic wave disperses 60-
90min is obtained.
Further, one kind in silver, copper, silver-colored copper-clad, ferroso-ferric oxide, nickel, zinc of the nano metal powder or
It is a variety of.
Further, the one kind or many of the film forming agent in polyacrylate, polyurethanes, epoxy resin
Kind.
Further, the waterproofing agent is the polymeric dispersant of containing silicone resin.
Further, the air-permeable layer slurry includes following raw material by weight：65 parts of polyurethane resin, wood powder
15 parts, 8 parts of foam improver, 0.7 part of bleeding agent, 0.9 part of wetting agent, 0.6 part of curing agent.
Further, the foam improver is selected from DDAO, alkyl polyglycoside, cocinic acid diethanol acyl
One or more in amine and coconut oil acyl propyl glycine betaine.
Further, the bleeding agent is aerosol-OT salt or AEO, the wetting
Agent is DBSA, and the curing agent is hydrophilic aliphatic polymeric isocyanate.
The present invention compared with prior art, with following beneficial effect：
The present invention realizes radiation proof by increasing the capability of electromagnetic shielding of leather substance, has abandoned traditional metal-powder direct
Nano metal powder is directly contacted each other in the method mixed with high polymer material, the present invention, forms interconnection conductive layers, only
It is to be remarkably improved electrical conductivity to need a small amount of metal-powder.This structure both ensure that the electrical conductivity of shielding material, can protect again
Shield metal-powder is difficult oxidation by air.The shielding mechanism of this natural leather with electromagnetic wave shielding performance is not simple
Reflection electromagnetic wave mechanism, but there is the ability of electromagnetic wave absorption and reflection electromagnetic wave simultaneously, significantly improve to electromagnetic wave
Shielding properties, and then improve the shielding property of leather substance.
The fluoride that the present invention is used by using the polymeric dispersant of containing silicone resin as waterproofing agent instead of tradition is prevented
Aqua, in leather surface and its can be internally formed water-repellent layer, and the water-repellent layer can play a part of waterproof and breathable, and then cause
The leather obtained is while have water resistance and permeability, and cost is relatively low.By being set between base fabric and water-repellent layer
Air-permeable layer, is internally formed micropore, is discharged the hot gas that user discharges through micropore using cross-ventilation principle, together
When also improve warming effect, so as to improve the comfortableness used, enhance one's market competitiveness, meet consumer demand.
