Abstract
The invention discloses a rotary drum dyeing method for fractionally dyeing superfine fiber synthetic leathers with multi-component dyes. The most common rotary drum equipment used in the natural leather processing process is adopted in the method. The method comprises the following steps of: adding a low temperature disperse dye to color polyurethane component in the superfine fiber synthetic leathers; lowering the pH value of dyeing solution to 5.5; adding a weak acid dye in the solution to color superfine fiber nonwoven fabric component in the superfine fiber synthetic leathers; lowering the pH value of the dyeing solution to 4.0; adding polycationic color fixing agent to fix the color; washing the leathers with water once after the completion; replacing the original dyeing solution with new dyeing solution; adding a neutral dye for dyeing; and washing the leathers with water once after dyeing. The disperse dye and the weak acid dye selected in the invention color the polyurethane component and the superfine fiber nonwoven fabric component in the superfine fiber synthetic leathers desirably; the neutral dye added in the final step enables evener and thicker color on the surface of the superfine fiber synthetic leathers; and thus the problem of dyeing difference between the two components in the superfine fiber synthetic leathers is solved.
Description
Technical field
The present invention relates to the production technology of superfine fiber chemical leather, particularly the drum method of dyeing that dyes step by step of a kind of multi-component dyes of superfine fiber chemical leather.
Background technology
The natural leather resource-constrained, production process can produce bigger pollution, have premium properties the emulation synthetic leather be developed to pursuit for the mankind.Be reinforcing material wherein with not weaving fabric of superfine fiber with tridimensional network, by flooding the superfine fiber chemical leather that polyurethane obtains, no matter aspects such as microstructure, or appearance tactile impression internally and physical characteristic and people's snugness of fit are all near natural leather.According to statistics, by 2008, the production capacity of Chinese superfine fiber chemical leather was about 7,500 ten thousand square metres, 4,500 ten thousand square metres of actual productions.The existing high-grade sport footwear more than 90% in the whole world adopts the superfine fiber chemical leather manufacturing, and high-grade automotive seat also begins 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 thoroughly not break through as yet, 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 bottleneck technology that does not break through as yet.
For the dyeing of superfine fiber chemical leather, its technological difficulties mainly contain following two aspects.One, on 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 big, and single dyestuff and single colouring method are difficult to satisfy the dyeing requirement of two kinds of compositions, two kinds of Colors that composition is difficult to reach good simultaneously; 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 groups, unprotected side chain only just has carboxyl and amino at the terminal of strand, mainly relies on the deposition of dyestuff self to make the fiber colouring during dyeing, 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 bigger, cost is higher, and present most of superfine fiber chemical leathers do not dye, just manufacture of intraocular coating on the superfine fiber chemical leather base cloth of white, be processed into finished product, the appearance luster of this product comes from artificial coating.The product that utilizes this superfine fiber chemical leather to make in use galls artificial coating and show-through easily as shoes and sofa etc., seriously influences the serviceability of product, is restricting the fast development of superfine fiber chemical leather.
Staining technique for superfine fiber chemical leather mainly contains the following aspects.(1) the one pack system dyeing technology that adopts high temperature-pressure dyeing machine to carry out.This technology is fit to industrialized production in enormous quantities, the production efficiency height, energy consumption is higher in the production process, the dyestuff of one-component is difficult to satisfy simultaneously the dyeing requirement of two kinds of compositions of superfine fiber chemical leather, wherein the colorability of a certain composition is relatively poor, it is inhomogeneous to dye, and dyefastness is bad, not water-fast washing.This technology only is used to the less demanding superfine fiber chemical leather that has face coat that dyes at present, 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 satisfy simultaneously multi-component dyes on dye requirement, simultaneously, exist the problem of dying in the competition between the multi-component dyes.Bulk dyeing dyeing is inhomogeneous, and dyefastness is bad, not water-fast washing, and the dyestuff absorptivity is lower.(3) the low-temperature atmosphere-pressure suction-type staining technique that adopts dyeing machine to carry out.The most tangible technical characterictic of this technology is dyeing under the low-temperature atmosphere-pressure, and the energy consumption of dyeing is lower.But this staining technique still exists dyeing inhomogeneous, and dyefastness is bad, and not laundry-resistant defective dyes under low-temperature atmosphere-pressure simultaneously, and the dye-uptake of dyestuff is lower, and raffinate contains more dyestuff, pollutes bigger.(4) color masterbatch composite spinning technology says it is dye technology on this technology stricti jurise, rather than staining technique.Its technical characterictic is to sneak into color masterbatch in the process of superfine fibre manufacturing, and the superfine fibre that obtains will have the color of the color masterbatch of adding, and the not weaving fabric of superfine fiber that processing at last obtains just has been with color.By the not weaving fabric of superfine fiber that this technology obtains, it is very high COLOR FASTNESS, still, the polyurethane composition needs later stage dyeing, the compound physical and mechanical properties that can influence fiber itself of color masterbatch, the combined amount of color masterbatch can not be too big, and the color that presents at last is not dense.The painted of early stage can limit the product development in later stage simultaneously, and it is single to produce product variety, is difficult to satisfy market demands; (5) color masterbatch 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 polyurethane to fill not weaving fabric of superfine fiber, in polyurethane, sneak into color masterbatch and be filled into together in the fine fibre non-weaving cloth, obtain superfine fiber chemical leather at last and have color.The COLOR FASTNESS that this technology obtains is fine.But the not weaving fabric of superfine fiber composition needs later stage dyeing, and the painted of early stage can limit the product development in later stage simultaneously, and it is single to produce product variety, is difficult to satisfy market demands; (6) adopt the technology of (4) and (5) simultaneously, this method and combine (4) and the technological merit of (5) also embodies the technological deficiency of (4) and (5).
