Abstract
A liquid-state disperse dye is prepared through reaction, press filter to obtain cake, dissolving it in acetone or alcohol, dissolving disperser in water, mixing them together while stirring, and heating for evaporating organic solvent.
Description
Technical field
The present invention relates to a kind of manufacture method of dispersed dye, especially a kind of manufacture method of aqueous ultra-fine dispersed dye.
Background technology
Dispersed dye refer to be scattered in the dye in the dye bath in the presence of dispersion agent.Contain polar group in the molecule, but do not contain water soluble groups such as sulfonic group, carboxylic acid group, the dissolving of dispersed dye in water is atomic.Dispersed dye are used for the dyeing and the stamp of synthon such as terylene, polypropylene fibre, polyamide fibre and spandex, it is the broad-spectrum dyestuff of a class, it is mainly used in the printing and dyeing of terylene and BLENDED FABRIC thereof, therefore the development of dispersed dye is closely related with the increase day by day of terylene output, is maximum a kind of of all dyestuffs uses.
The former dyestuff of dispersed dye by reaction obtains will obtain filter cake through press filtration usually, obtains the dispersed dye finished product again after sand milling and spraying drying.Wherein sand milling technology has determined the granular size of dispersed dye finished products, and the granular size of the dispersed dye that obtain by above-mentioned technology generally about 2 microns, even through long-time sand milling, also is difficult to the granular size of dispersed dye is distributed to below 1 micron.And the granular size of dispersed dye directly has influence on painted cost and dyeing quality, and especially the assembly of widespread use mixes dispersed dye in the printing and dyeing, can influence the color and luster effect greatly because of the particle of dyestuff.The granular size that reduces dispersed dye can improve the color and luster effect of dyestuff, improves the exhaustion of dyestuff, reduces the cost of dispersed dye in the dyeing course, simplifies dyeing and improves dyeing quality.
Summary of the invention
The problem that quasi-solution of the present invention is determined provides a kind of manufacture method of dispersed dye, the particle diameter that makes dispersed dye improves the exhaustion of dyestuff in the 10-100 nanometer, reduces the cost of dispersed dye in the dyeing course, improve to piece together and mix dispersed dye color and luster effect, simplify dyeing and improve dyeing quality.
For addressing the above problem, the present invention by the following technical solutions: a kind of manufacture method of aqueous dispersed dye, it obtains filter cake by the dispersed dye crude product that reaction obtains through press filtration, it is further comprising the steps of:
A: described filter cake is dissolved in the organic solvent, obtains solution A;
B: dispersion agent is dissolved in the water, obtains solution B;
C: under agitation condition, solution A and solution B are mixed, obtain mixed solution C;
D: to mixed solution C heating, boil off the organic solvent among the described mixed solution C, obtain aqueous dispersed dye.
Filter cake preferably drying processing before dissolving among the above-mentioned steps a; Described organic solvent can be an acetone or alcohol, and the weight ratio of filter cake and acetone or alcohol is 1: 4;
The manufacture method of above-mentioned aqueous dispersed dye, the dispersion agent among the step b are Dispersant MF or dispersion agent sulfonated lignin.The weight ratio of dispersion agent and water is 1: 4.
The manufacture method of above-mentioned aqueous dispersed dye, the solution A of described step c and solution B mixing preferably join A in the solution B; Described stirring preferably adopts the emulsification shears to stir.
The manufacture method of above-mentioned aqueous dispersed dye, in the described steps d to the Heating temperature of mixed solution C for being heated to 90-98 ℃, in heat-processed, preferably stir.
Conventional dispersed dye manufacture method, the filter cake that the dispersed dye crude product obtains after press filtration forms fine and close disperse dyes granule, because intermolecular reactive force in the disperse dyes granule, by mechanical disintegration,, only can make disperse dyes granule be distributed to the 1-2 micron as technologies such as sand millings.And adopted the present invention program, promptly by filter cake is passed through to use organic solvent dissolution, make dyestuff fully be distributed in the solvent with molecular level, when the aqueous solution of this solution and dispersion agent, because solubility change, dispersed dye can be separated out again, at first generate nano level small-particle when separating out, because the effect of factors such as stirring, particularly a large amount of existence of dispersion agent, the dyestuff small-particle is wrapped up by dispersion agent rapidly, forms emulsified disperse dyes granule, stoped intergranular interaction and particulate further to be grown up, obtaining particle is the aqueous dispersed dye of 10～100 nanometers.The dispersed dye that adopt present method to obtain, the exhaustion that can improve dyestuff to reduce the cost of dispersed dye in the dyeing course, especially can improve and piece together the color and luster effect of mixing dispersed dye, simplifies dyeing and improves dyeing quality.In addition, add heat extraction organic solvent cyclically utilizing, so both can save production cost, can not cause environmental pollution again.
