Description
Technical field
The present invention relates to the preparation method of a class superfine fiber chemical leather dedicated dye.
Background technology
The natural leather resource-constrained, production process can produce larger pollution, have premium properties simulated composite leather be developed to the pursuit for the mankind.The not weaving fabric of superfine fiber with tridimensional network of wherein take is strongthener, the superfine fiber chemical leather obtained by dipping urethane, no matter the aspects such as microtexture, or appearance tactile impression internally and physical property and people's snugness of fit have 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 high-grade sports shoes more than 90% in the whole world adopts the 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 processing technology, still there are some crucial technology not yet thoroughly to break through, become the serious hindrance of superfine fiber chemical leather development, wherein, the staining technique of super long and slender dimension 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 urethane 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 dyeing process 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 the superfine fiber chemical leather fiber seldom, the molecule middle-of-chain exists a large amount of carbochains and amide group, unprotected side chain, only the end at molecular chain just has carboxyl and amino, during dyeing, mainly relies on the sedimentation of dyestuff self to make the fiber colouring, therefore, most of dyestuffs are difficult to dye, and its washing fastness is very poor, is difficult to reach the dyeing requirement.
Because the dyeing difficulty of superfine fiber chemical leather is larger, cost is higher, and the most superfine fiber chemical leather is not dyeed, just manufacture of intraocular coating on white superfine fiber synthetic leather base cloth, be processed into finished product, the appearance luster of this product comes 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 use properties that affects product is restricting the fast development of superfine fiber chemical leather.
Staining technique for superfine fiber chemical leather, mainly contain the following aspects.(1) the single component 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 tinting strength 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 top coat that dyes, and to the velour 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 urethane of not weaving fabric of superfine fiber and dipping filling separately to a certain extent, but dyeing with bathing under the same terms, processing condition be difficult to meet simultaneously multi-component dyes on dye requirement, simultaneously, exist the problem of dying in competition between multi-component dyes.Bulk dyeing is inhomogeneous, and dyefastness is bad, not water-fastness, and the dyestuff specific absorption is lower.(3) the low-temperature atmosphere-pressure inhaling type staining technique that adopts dyeing machinery 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) colour batch composite spinning technology, say it is dye technology on this technology stricti jurise, rather than staining technique.Its technical characterictic is to sneak into colour batch in the process of ultra-fine fibre manufacture, and the ultra-fine fibre obtained will be with the color of the colour batch added, and the not weaving fabric of superfine fiber that finally processing obtains just has been with color.The not weaving fabric of superfine fiber obtained by this technology, colour fastness very high, still, the urethane composition needs later stage dyeing, the compound physical and mechanical properties that can affect fiber itself of colour batch, the combined amount of colour batch can not be too large, and the color finally presented is not dense.The painted of early stage can limit the product development in later stage simultaneously, produces range of product single, is difficult to the satisfying the market requirement; (5) colour batch composite polyurethane filling technique.Technology type in this technology and (4) seemingly, be exactly in the process of producing superfine fiber chemical leather, when utilizing the non-manufacture cloth of filling polyurethane ultra-fine fibre, sneak into colour batch and be filled into together in the non-manufacture cloth of fine-fibered in urethane, finally obtaining superfine fiber chemical leather with color.The colour fastness that this technology obtains is fine.But the 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 range of product single, is difficult to the satisfying the market requirement; (6) adopt the technology of (4) and (5), this method and combine (4) and the technological merit of (5), also embody the technological deficiency of (4) and (5) simultaneously.
Summary of the invention
