Abstract

A rare-earth dyeing assistant is a multi-component and multi-function dyeing assistant with high-molecule rare-earth complex as the main component. It is composed of ethylenediamine, polyelhylene polyamine, trimethylamine, divinyl triamine, glycol, chloropropylene oxide, dodecyl betaine, chloroacetic acid and rare earth. It concentrates level dyeing, dye fixing and darkening into one body, may raise the binding power of dye and blank leather, increase dyeing fastness, and at the same time, may increase colour depth (saturation degree and brightness); raise the degree of dyeing and save red alum, lower Cr2O3 content in waste water, and at the same time, raise the exhausting degree of fattening agent and so save fattening agent to play the role of grease fixing. This dyeing assistant, besides used for leather, may be further used for cotton, articial cotton, fur, wool, hemp, flax and chemical fibre.

Description

Rare-earth dyeing assistant and preparation technology thereof
Leather coloring auxiliary agent involved in the present invention is to be many components of main component with the polymer rare-earth complex, the multifunctional dyeing auxiliary agent.
Background technology of the present invention: the present used proprietary dyestuff rareness of leather industry, and acidity, direct dyeing fastness commonly used are poor, tone is not full, and dye dosage is big during dyeing, cost is high, chroma in waste water is dark.Be difficult to dye dark-toned leather when particularly the crust leather after the anionic acrylic resin retanning is with anionic acidity, direct dyestuff, particularly dye the black leather.So just hindered the widespread use of acrylic resin retanning agent in leather retanning.
Purpose of design of the present invention: the one, the colouring problem that solves acrylic resin retanning crust leather.Leather agent can change the electriferous state of crust leather, improve of the absorption of resin retanning crust leather to anionic dyestuff and fatting agent, resin retanning crust leather with the rare-earth additive processing, the leather color of being dyed is pure, tone is full, bright-coloured, the colouring problem that solved acrylic resin retanning crust leather, even it is also very good to dye the black effect, reached the degree that the chrome tanning crust leather dyes black.The 2nd, improve dyefastness, reduce dye dosage, simplify production technique.Rare-earth additive is used for leather coloring, its level dyeing, the effect that increases dark and fixation are all fairly obvious, can play and prevent the look flower, the institute dye the leather color even, pure, tone is full, bright-coloured, improved the dye uptake of dyestuff, can improve dyefastness 0.5--1 level, saved dyestuff 10--25% leather, suede garment leather secondary dyeing (chromatography) can be changed into once dyeing, simplify production technique.
Design of the present invention: the present invention synthesizes the macromolecule complex body earlier, then itself and rare earth is formed title complex, composite again other material, thus synthesize the rare earth high polymer complex compound.
1, rare-earth additive help that to dye function as follows:
Synthesizing of a, macromolecule complex body:
Figure A9710385500041
Figure A9710385500042
Figure A9710385500051
Anionic dyestuff (acid, direct dyestuff) and crust leather fiber are mainly with the electrovalent bond combination, and the electrovalent bond bonding force is not strong; Moreover it is not the sulfonic group isoreactivity base wetting ability of dye molecule is strong, thereby water-fast.Desire improves fastness of dyeing, must improve the bonding state of dyestuff and fiber.
Figure A9710385500052
Sulfonic group effect among middle ortho-nitrogen ion and the D-SO3H is played tint retention, simultaneously Can play the effect of regulating molecular weight.
Have among product (B) in reaction (2), (3), (C)-NH-,-the nitrogenous active group of NH2, under the low situation of pH value, do not show electrically; When under the high situation of pH value, thereby become-NH2-,-NH3 can react with anionic dyestuff like this and generate the color lake.
Figure A9710385500061
Product (B), (C) and the combination of acrylic resin retan in reaction (2), (3) increase its cation group, help like this dying on the anionic dyestuff.
Figure A9710385500062
HOCH2CH2OH in the reaction (4) can regulate positive charge in the molecular chain, avoids crosslinked strong excessively simultaneously, causes that grain is coarse.
B, graft reaction
Connect branch
Figure A9710385500064
After, product (E), (F) more help the chromium in the chrome tanned leather to carry out coordination, are simultaneously and rare earth ion increase complex ability.
The complex reaction of c and rare earth ion
More than each product can with rare earth ion generation complex reaction, thereby form rare-earth complex.The hapto that complexing takes place is-NH2 ,-OH ,-COOH isoreactivity group.
Like this, delocalization effect takes place with dyestuff, the crosslinked multicomponent system of having formed of fiber in rare-earth complex, so maximum system energy descends, absorbing wavelength moves to long wave, and hyperchromic effect takes place.Moreover increase the dyestuff binding site, and increasing the dyestuff dye uptake, absorption peak strengthens, and makes color and luster dense.The rare earth complex ion causes the dyestuff absorption spectrum to narrow down simultaneously, makes the finished leather tone full, pure.
Composite other tensio-active agent Pluronic.
Law of compound according to tensio-active agent adds Pluronic in its system, improve perviousness and level-dyeing property.
