Description
(1) technical field
The present invention relates to a kind of preparation method of emulation skin artificial leather, be specifically related to a kind of preparation method of superfine fiber sofa leatherette.
(2) background technology
In the leather technology field, the branch of natural leather and artificial synthetic leather is arranged." corium " is common printed words on leather and fur products market, is that people are a kind of custom call of difference synthetic leather to natural leather; In consumer's idea, " corium " also has the connotation of non-vacation.In fact, corium is exactly leather, and it mainly is to be processed by the mammal skin.Corium is of a great variety, and is numerous in variety, the structure difference, and quality is different, and price equates great disparity.Therefore, corium is the general designation of all natural leathers, also is ambiguous sign on the commodity market.
Natural leather comes branch to mainly contain pig leather, ox-hide leather, sheep, horse skin leather, donkey hide leather and kangaroo leather etc. by its kind, and other has a spot of fish-skin leather, reptile leather, amphibian animal leather, ostrich leather etc.Its heifer leather divides ox leather, buffalo leather, yak leather and pien niu leather again; Sheep is divided into sheepskin and goat upper leather.By its level branch, first layer leather and second layer leather are arranged, wherein first layer leather has full grain and the leather of having a shave; Second layer leather has pig split leather and cow split leather etc. again.In main a few class leathers, ox leather and sheepskin, its surface is flat thin, and the hair eye is little, the fine and closely woven consolidation of immanent structure, the leather body has plentiful preferably and elastic sensation, good physical performance.Therefore, excellent ox leather and glace kid leather generally are used as the cladding of high-grade goods, and its price is a higher class in the large leather.In many leather kinds, full grain should occupy the umber one, because it is to be processed by the less first-class raw material skin of permanent disability, keeps intact native state on the leather surface, and coating is thin, can show the white right decorative pattern U.S. of Animal Skin.It is not only wear-resisting, and has air permeability and good.
Second layer leather is a pachydermia to be cutd open layer and get with splitter, and the head layer is used for doing full grain or the leather of having a shave, and serial operations such as two layers of process covering with paint or pad pasting are made second layer leather, and its fastness, ABRASION RESISTANCE are relatively poor, is the most cheap a kind of in the similar leather.Yet the variety classes leather has similarity in appearance with on the immanent structure, as horse skin leather and ox-hide leather, ox leather and yak leather, donkey hide leather and sheep, kangaroo leather and calf leather etc.Along with the raising of leather processing technology, leather can make it changed beyond recognition through ornamenting and imitated embossing, and original some feature is covered, makes through cutting out to cut apart with exquisiteness again, and it has actually and belongs to which kind of leather, with the naked eye almost is difficult to identification.Compare with common people's fabricate-leather, leather has following good performance:
One, good hand touch: touch leather surface with hand, if any smooth, softness, plentiful, flexiblely feel it is corium; And general artificial synthetic leather face surface is sent out puckery, and inflexible, flexibility is poor; But that passes through special treatment also can reach similar effects.
Two, poisture-penetrability is good: because the corium leather surface has pore more clearly, (as: cattle hide has more well-balanced fine, soft fur hole to decorative pattern, and the yak skin has thicker and sparse pore, and goat skin has cataphracted pore, pigskin has the triangle enlarged pores) therefore, the vapor transfer rate of most of corium is all at 800g/m
2More than the 24h, water vapour permeability is better.And artificial leather, although also copied pore, but unintelligible, and the artificial leather water vapour permeability of different materials manufacturing differs bigger: polyvinyl chloride (PVC) artificial leather is nearly all airtight, the water vapour permeability adjustable range of polyamine fat (PU) artificial leather big (vapor transfer rate from less to 2000g/m
224h).
Three, mechanical strength is good: though according to the type difference of leather, its mechanical strength is slightly different, can both satisfy multiple requirement.For example the ox-hide leather surface is thin, the intensity height, and optimum is made leather shoes; Sheep is light, and is thin and soft, is the desirable lining of leather wear; The air-and water-permeable vapour performance of pig leather is good, is suitable for manufacturing underwear and articles for children; The fibre structure of horse skin leather comparatively closely, intensity is also than higher, is used to make chaparajos and the leather boots effect is better.And artificial leather mechanical strength and leather are suitable.
Four, resistance to low temperature is good: because most of composition of leather is an animal protein, therefore have resistance to low temperature preferably.General artificial leather is then done the composite of base and synthetic resin be combined into textiles or nonwoven fabric, be a kind of plastic products that belong to similar natural leather.Therefore their cold resistance is relatively poor, crosses cold meeting hardening, embrittlement.
Five, good hygroscopicity: the hydrophily of animal protein and water absorbing properties all are better than the sizing material of used for artificial leather, so the moisture pick-up properties of natural leather will obviously be better than common people's fabricate-leather.
With the polyurethane artificial leather is example, and artificial leather and natural leather performance are relatively tabulated as table 1-1.
Table 1-1 polyurethane artificial leather and the tabulation of natural leather performance

1) sample is at 20 ℃, and is saturated under relative humidity 60% condition, keeps moisture absorption 40h under relative humidity 90% conditions at 20 ℃ again.
2) Corfam is a kind of polyurethane artificial leather trade names of the U.S..
More superior than natural leather from the surface abrasion resistance and the cryogenic property of the polyurethane artificial leather more as can be seen of polyurethane artificial leather and natural leather, mechanical strength is near natural leather.Yet the hygroscopicity of polyurethane artificial leather and poisture-penetrability are all not as natural leather.
As everyone knows, corium has good anti-wear performance, resistance to deflection energy, water vapour permeability and feel preferably, therefore is widely used in industries such as shoemaking, sofa, interior decoration, clothes
Common people's fabricate-leather can be made the outward appearance product similar with leather, and its permeability has certain mechanical strength and anti-wear performance, and has performances such as acidproof, alkaline-resisting, water-fast not as good as natural leather.Polyurethane artificial leather has good water vapour permeability, chemical resistance, good hand feeling, outward appearance is beautiful, warming, feel is not subjected to cold and Warm Changes in Northern advantages such as influence.The performance of polyurethane artificial leather determined by the density of length, fiber number and the fabric of the synthetic fiber itself of base material etc., also depends on the thickness material of the fine porous layer of polyurethane and composition etc., and its performance also is subjected to the influence of incrustation material.In a word, the factor that influences polyurethane artificial leather is a lot, but key is the performance of sizing material itself.
