Description

A kind of synthetic leather
Technical field
The utility model relates to the material technology field, relates in particular to a kind of synthetic leather.
Background technology
Synthetic leather has the production history of decades.Produce in Italy the earliest, then five, the sixties import China into.Synthetic leather is extensively applied to fields such as shoemaking, case and bag, sofa, clothes and packing now.The generation of synthetic leather and development have significantly reduced human dependence to corium.Synthetic leather divides PU and two kinds of different process of PVC, because more environmental protection of PU, so the PU synthetic leather is applied to each field more widely.The PU synthetic leather is mainly synthetic by chemical reaction by PU resin and leather base cloth.Present leather base cloth mainly by cotton, wash, material blending such as viscose glue forms.
The use of synthetic leather on shoe-making industry: synthetic leather can be used for vamp and shoe lining, traditional leather base cloth is made by raw material such as cotton and wash, can't use owing to can wear out after synthetic leather uses for many years, blending product cotton and that wash can't finally be degraded, and can produce certain influence to environment.Simultaneously, in the production and selling process, the client also can propose higher ventilative and antibiotic requirement to shoes.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of synthetic leather, and gas permeability and good anti-bacterial effect are used material low-carbon (LC), environmental protection.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of synthetic leather comprises bamboo fiber-based layer of cloth, and synthesizing on the bamboo fiber-based layer of cloth has the PU resin bed.
In the technique scheme, can be that the upper and lower surface of described bamboo fiber-based layer of cloth is the PU resin bed, the one side that also can be described bamboo fiber-based layer of cloth be the PU resin bed.In addition, can also on the face of above-mentioned synthetic leather, increase other coatings again according to the needs that use.
The nonwoven fabric that the employing bamboo fibre is made is as the leather base cloth, and the bamboo fibre that will have " natural ", " environmental protection " advantages such as " natural antibacterials " applies to leather industry, is initiative in China and even world's curriery.Bamboo fibre is to endure the Hsinchu held together with 2-3 vivid, the stalwartness in pool of adding lustre to, and becomes bamboo pulp, extracts fiber, makes cotton shape through thermophilic digestion, adopts hydrolysis alkaline process and how bleached refined and pulping cypress, and then is processed into fiber, is formed by weaving at last.Along with being directed at the famine of not only the increasing of fiber product demand, chemical raw material resource, the mankind human its own existence environment damage is excessively developed; press for the very strong natural raw material of a kind of reproducibility and replace chemical raw material; human in the textile product that uses pure natural to ensure; protect our living environment, promote the survival and development of human natural health.The bamboo fibre product is given birth at once.Bamboo in the process of growth, without any pollution sources, growth cycle is short, reproducibility is strong, comes from nature fully, and bamboo fibre can be degraded, without any pollution, back to nature completely again is so this fiber is called as Recycled Fibers to environment for degraded back.Bamboo fibre toughness, flexibility are strong, belong to the natural green material, kept bamboo antibiotic, remove the characteristic and the natural faint scent of mite, heat-clearing, detoxifcation.Have air permeability and good, hygroscopicity, unique resilience, moment water imbibition, therefore be called as " ecological fiber that can breathe ".Under 2000 times of electron microscopes, observe, the cross section deformation of unevenness of bamboo fibre, be covered with and be similar to oval-shaped hole, be height hollow, capillary effect is extremely strong, can be at transient absorption and transpiring moisture, in all natural fabrics, the absorb-discharge humid of bamboo fibre and gas permeability are best, are that 36 ℃, relative humidity are under 100% the condition in temperature, the regain of bamboo fibre surpasses 45%, and gas permeability is stronger 3.5 times than cotton.Contain a kind of antibacterial material that is called " bamboo a kind of jade " in the bamboo fibre, have the medicinal property of natural antibacterial, anti-mite, deodorization, bamboo juice (bamboo vinegar) has the anti-widely thing function of supporting one's family, and chlorophyll in the bamboo fibre and chlorophyll copper sodium have deodorization preferably.Through the whole world maximum check, test and the SGS of certification authority, the detection that utilizes the modern science detection means that the antibiotic property of bamboo fibre is carried out, the result confirms that the bacteriostasis rate on the bamboo fibre reached about 95% in 24 hours.After bamboo fibre is utilized synthetic leather, continued to keep its characteristic, made its synthetic leather of making satisfy the demand of shoe industry, quality softness as natural fabric, ventilative moisture sorption effect is good, and the footwear of making have other fabric leather base cloth products inside the natural antibacterial effect that does not have is arranged.And the shoe lining made from bamboo fibre and vamp finally can starch and separate, and environment is not produced pollution, is the product of a kind of real environmental protection, low-carbon (LC), also is an innovation to whole leather industry.
The bamboo fibre synthetic leather is fit to two kinds of production technologies: contain method of being coated with (product is fit to vamp, clothes etc.) and infiltration and send out (product is fit to shoe lining etc.).
1. contain the method for being coated with and be the leather base cloth of bamboo fibre infuse in containing certain density PU earlier, press dry by rubber rollers then and (keep a little P U resin on the bamboo fibre, make back side feel that kishke feel be arranged), boiling hot roller oven dry through high temperature, then coat the PU resin of uniform thickness again, the bamboo fibre base cloth that then has the PU resin passes through the washing of impregnation and multiple tracks together, pushes at last and oven dry becomes the bamboo fibre synthetic leather.
2. this technology utilization of osmosis is fewer, its controllability is more difficult than the former, utilization is few at home, and utilization is more more in Italian leather industry, osmosis is that the PU resin of certain viscosity prescription is directly beaten on the leather base cloth of bamboo fibre with air pump, the chemical industry material can infiltrate into its back side at leisure, and the leather base cloth that bamboo fibre is made is enclosed in the PU resin, then also is through impregnation and washing and oven dry.Its back side and surface are through polishing, and feel is better, has more kishke feel.
Above-mentioned bamboo fiber-based layer of cloth is the bamboo fibre cloth, it can be 100% pure bamboo fibre nonwoven fabric, but because its fiber of bamboo fibre, it is powerful or not ideal enough, and the synthetic leather that adopts pure bamboo fiber-based cloth to make has reached every test request in the utilization of shoe lining.For vamp and other utilization, also can suitably increase a certain proportion of nylon and increase the brute force of bamboo fibre base cloth finally to reach the powerful requirement of bamboo fibre synthetic leather.
