Abstract
The invention relates to a preparation method for electric property-controllable organic pigment dispersion, and belongs to the technical field of textile dyeing and finishing. The preparation method is characterized by comprising the following steps: adding a certain quantity of cellulase into water to ensure that the mass concentration of zymoprotein is 0.1 to 1 g/L; adjusting the pH of the mixed solution to be 7; adding an organic pigment of which the mass is 10 to 20 times of that of the zymoprotein; treating the liquid in a phacofragmentation condition for 30 to 40 min; adjusting the pH of the dispersion liquid to be 3 to 10 with acetic acid or sodium hydroxide as required. The preparation method has the advantages that the organic pigment dispersion prepared according to the method is stable; the electric property of the organic pigment dispersion can be adjusted and controlled by adjusting the pH value of the dispersion liquid.
Description
Technical field
The present invention relates to a kind of preparation method of electrical controlled organic pigment dispersions, particularly utilize cellulase to prepare the method for electrical controlled organic pigment dispersions, belong to technical field of textile printing.
Background technology
Except dyestuff, organic pigment dispersions also can be used for the dyeing of all kinds of textiless, and have that technical process is short, energy-conservation, the advantage such as discharge of wastewater is few, to be that textile printing and dyeing industry is carried out energy-conservation, one of consumption reduction, the gordian technique that reduces discharging.In pigment dyestuff precursor structure, lack water soluble group and there is stronger hydrophobicity, be difficult to be dispersed in aqueous medium.Therefore, must to it, carry out surface modification according to pigment dyestuff constitutional features, then by powerful smashing effect, making it to form stable primary granule dispersion could be for the dyeing of textiles.Pigment dyestuff surface modification mainly relies on negatively charged ion or the cation dispersing agent with suitable construction to realize, dispersion agent makes it with a certain amount of negative or positive electric charge after being combined with surface of pigments, rely on the stability of the repulsive interaction maintenance pigment dispersion system of like charges.Now, being electrically just fixed up of pigment dispersion, can not adjust flexibly according to actual needs.
Cellulase is the general name of the cellulosic enzyme of catalytic hydrolysis, mainly endoglucanase, exoglucanase and beta-glucosidase, consists of, and three is collaborative plays hydrolyzation catalysis effect to Mierocrystalline cellulose.The chemical nature of cellulase is protein, generally 20 kinds of L-type amino acid, consists of, and presents certain colloid property in the aqueous solution.According to the difference of side group structure, amino acid can be divided into 4 classes: neutral amino acids, acidic amino acid, basic aminoacids and aromatic heterocycle amino acid.Because alkaline and acidic amino acid exist simultaneously, protein presents typical amphoteric properties, and it electrically can regulate and control according to the variation of outside acid or alkali environment.
Summary of the invention
The object of this invention is to provide a kind of method of preparing electrical controlled organic pigment dispersions, its charged character can regulate according to the variation of outside acid or alkali environment, makes the range of application of organic pigment dispersions wider, and application mode is more flexible.
The present invention includes following technique: in water, add a certain amount of cellulase, make zymoprotein quality concentration at 0.1-1g/L, regulating the pH of mixing solutions is 7, adding quality is zymoprotein 10-20 pigment dyestuff doubly, under ultrasonication condition, process 30-40min, finally with acetic acid or sodium hydroxide, dispersion liquid pH is adjusted between 3-10 as required.
First, add a certain amount of cellulase and make it abundant dissolving in water, zymoprotein quality concentration is at 0.1-1g/L, and cellulase used is commercially available polishing cellulase.Regulate mixing solutions pH to neutral, adding quality is zymoprotein 10-20 pigment dyestuff doubly, and the impact that utilizes ultrasonic cavitation effect to produce is broken by pigment dyestuff, and time dimension is held in 30-40min.Between cellulase protein and pigment dyestuff surface, there is stronger hydrophobic sucking action, impel zymoprotein to be adsorbed to surface of pigments.Under neutrallty condition, cellulase protein molecule integral body is electronegative, and therefore surface of pigments also presents electronegativity, relies on electrostatic repulsion to keep the dispersion stabilization of pigment.Subsequently, can be by regulating the mode of dispersion liquid pH value to adjust and to control surface of pigments electrical.When pH is during higher than cellulase iso-electric point, surface of pigments is electronegative, and negative electricity place value raises and increases with pH; When pH value is during lower than iso-electric point, on schedule, and positive electricity place value reduces and increases with pH surface of pigments band.The regulation range of pH, between 3-10, exceeds after this scope, and the stability of pigment dispersion, by variation, affects its follow-up effect.
