Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to provide a preparation method of mineral printing paste for the problems of insufficient color yield and unsatisfactory color fastness of the existing printing paste, and the printed products produced have a rough handle. In this method, the yeast powder is activated in warm water, kneaded into a dough with bentonite and flour, and then left to ferment to make it sour to initially activate the bentonite and form a porous structure. Carbonize the starch in the powder to obtain modified bentonite powder, then mix and ferment the kelp shreds and biogas liquid and soak them in sodium carbonate solution to dissolve the effective organic components in the kelp shreds, then filter with suction, and mix the filtrate with the above modified Bentonite powder is mixed, and earthworms are used to swallow the mixture to transform it into water-stable aggregates, which are then discharged in the form of feces, and finally the vermicompost is dried and ground into powder to obtain the mineral printing paste. The printing paste prepared by the present invention is High color quantity, good color fastness, and the printed products have a good hand feeling, which has a broad application market

Abstract

The invention discloses a preparation method of mineral printing paste and belongs to the technical field of textile printing dye preparation. Yeast powder is activated in warm water and then is mixed with bentonite and flour, the mixture is kneaded into dough and then left to stand for fermentation, the mixture is fermented to preliminarily activate bentonite, a porous structure is formed, the fermented dough is dried, smashed and calcined, the bentonite is further activated, starch in powder is carbonized, modified bentonite powder is obtained, shredded kelp and a biogas liquid are mixed and fermented and then are soaked with a sodium carbonate solution, effective organic ingredients in the shredded kelp are dissolved and subjected to suction filtration, filtrate and modified bentonite powder are mixed, earthworms eat the mixture, the mixture is converted into water-stable aggregate and discharged in a faeces form, finally, earthworm cast is dried and ground into powder, and the mineral printing paste is obtained. The mineral printing paste has high color yield and good color fastness, and a prepared printed product touches well and has broad application market.

Description

technical field [0001] The invention discloses a preparation method of mineral printing paste, which belongs to the technical field of textile printing and dyeing preparation. Background technique [0002] Printing paste refers to a polymer compound that can thicken the printing paste. Before printing paste is added to printing paste, it is generally a thick colloidal solution of hydrophilic polymer that is soluble in water or fully swollen and dispersed in water. When preparing printing paste, part of the dye is dissolved in water, and the other part is dissolved, adsorbed or dispersed in the original printing paste. Printing paste is an important main component of printing paste, which determines the running performance of printing, the amount of color given to the surface of the dye, the clarity of the outline of the pattern, the smoothness, the feel, etc. [0003] At present, most of the textile reactive dye printing adopts the traditional screen printing process, incl...
