Description
Technical field
The present invention relates to the preparation method of a class superfine fiber chemical leather dedicated dye.
Background technology
Natural leather resource-constrained, production process can produce larger pollution, have premium properties simulated composite leather be developed to the pursuit for the mankind. Wherein taking the not weaving fabric of superfine fiber with tridimensional network as reinforcing material, the superfine fiber chemical leather obtaining by dipping polyurethane, no matter from internal microstructure, or the aspect such as appearance tactile impression and physical characteristic and people's snugness of fit has all approached natural leather. According to statistics, by 2012, the annual capacity of Chinese superfine fiber chemical leather was about 9,500 ten thousand square metres of left and right, 7,500 ten thousand square metres of left and right of actual annual production. The existing more than 90% high-grade sport footwear in the whole world adopts superfine fiber chemical leather manufacture, and high-grade automotive seat also starts to adopt superfine fiber chemical leather to substitute natural leather.
In the fast development of superfine fiber chemical leather process technology, still there are some crucial technology not yet thoroughly to break through, the serious hindrance that becomes superfine fiber chemical leather development, wherein, the staining technique of super fine fiber synthetic leather is exactly one of its Pinch technology of not yet breaking through.
For the dyeing of superfine fiber chemical leather, its technological difficulties mainly contain following two aspects. One, component, superfine fiber chemical leather mainly comprises two kinds of compositions of polyurethane that not weaving fabric of superfine fiber and dipping are filled. These two kinds of constituent structure and performance difference are very large, and single dyestuff and single colouring method are difficult to meet the dyeing requirement of two kinds of compositions, and two kinds of compositions are difficult to the Color that simultaneously reaches good; They are two years old, active group on superfine fiber chemical leather fiber is little, there is a large amount of carbochains and amide groups in molecule middle-of-chain, unprotected side chain, only just has carboxyl and amino at the end of strand, mainly relies on the deposition of dyestuff self to make fiber colouring when dyeing, therefore, most of dyestuffs are difficult to dye, and its washing fastness is very poor, is difficult to reach dyeing requirement.
Because the dyeing difficulty of superfine fiber chemical leather is larger, cost is higher, and most superfine fiber chemical leather does not dye, just manufacture of intraocular coating on white superfine fiber synthetic leather base cloth, be processed into finished product, the appearance luster of this product is come this in artificial coating. The product that utilizes this superfine fiber chemical leather to manufacture, as shoes and sofa etc. in use easily gall artificial coating and show-through, the serious serviceability that affects product is restricting the fast development of superfine fiber chemical leather.
For the staining technique of superfine fiber chemical leather, mainly contain the following aspects. (1) the one pack system dyeing technology that adopts high temperature-pressure dyeing machine to carry out. This technology is applicable to industrialized production in enormous quantities, production efficiency is high, in production process, energy consumption is higher, the dyestuff of one-component is difficult to meet the dyeing requirement of two kinds of compositions of superfine fiber chemical leather simultaneously, wherein the colorability of a certain composition is poor, dye inhomogeneous, dyefastness is bad, not water-fastness. This technique is at present only for the less demanding superfine fiber chemical leather with face coat that dyes, and to the suede of band coating not, this staining technique does not reach requirement at all; (2) the multi-component dyes staining technique that adopts high temperature-pressure dyeing machine to carry out. The selection of multi-component dyes, multi-component dyes is suitable for the painted requirement of the polyurethane of not weaving fabric of superfine fiber and dipping filling separately to a certain extent, but dyeing with bathing under the same terms, process conditions be difficult to meet simultaneously multi-component dyes on dye requirement, meanwhile, between multi-component dyes, exist the problem of dying in competition. Bulk dyeing is inhomogeneous, and dyefastness is bad, not water-fastness, and dyestuff absorptivity is lower. (3) the low-temperature atmosphere-pressure suction-type staining technique that adopts overflow dyeing machine to carry out. The most obvious technical characterictic of this technology is dyeing under low-temperature atmosphere-pressure, and the energy consumption of dyeing is lower. But this staining technique still exists dyeing inhomogeneous, and dyefastness is bad, not laundry-resistant defect dyes simultaneously under low-temperature atmosphere-pressure, and the dye-uptake of dyestuff is lower, and raffinate contains more dyestuff, pollutes larger. (4) color masterbatch composite spinning technology, says it is dye technology on this technology stricti jurise, instead of staining technique. Its technical characterictic is to sneak into color masterbatch in the process of superfine fibre manufacture, and the superfine fibre obtaining will be with the color of the color masterbatch adding, and the not weaving fabric of superfine fiber that finally processing obtains has just been brought color. The not weaving fabric of superfine fiber obtaining by this technology, color fastness very high, still, polyurethane composition needs later stage dyeing, the compound physical and mechanical properties that can affect fiber itself of color masterbatch, the combined amount of color masterbatch can not be too large, and the color finally presenting is not dense. The painted of early stage can limit the product development in later stage simultaneously, produces product variety single, is difficult to meet market demands; (5) color masterbatch composite polyurethane filling technique. Technology type in this technology and (4) seemingly, be exactly in the process of production superfine fiber chemical leather, in utilizing the non-manufacture cloth of filling polyurethane superfine fibre, in polyurethane, sneak into color masterbatch and be filled into together in the non-manufacture cloth of fine fibre, finally obtaining superfine fiber chemical leather with color. The color fastness that this technology obtains is fine. But not weaving fabric of superfine fiber composition needs later stage dyeing, the painted of early stage can limit the product development in later stage simultaneously, produces product variety single, is difficult to meet market demands; (6) adopt the technology of (4) and (5), this method and combine (4) and the technological merit of (5), also embodies the technological deficiency of (4) and (5) simultaneously.
