Technical Field

the invention relates to a preparation method of a carrier composite material, in particular to a preparation method of a carrier for attaching a dye.

Background

Dyes are organic compounds that give other materials a vivid and strong hue, and are also called synthetic dyes because pigments used at present are artificially synthesized. Dyes and pigments are generally compounds which are inherently coloured and which are capable of giving other substances a vivid and strong shade in the molecular or dispersed state. At present, the most used dye in textile industry is direct dye, and the dye can be directly dyed on various fibers such as cotton, hemp, silk, wool and the like without depending on other medicaments. However, the dyeing method is simple, complete in color spectrum, low in cost and poor in washing fastness and light fastness.

Disclosure of Invention

The purpose of the invention is as follows: the invention solves the problems of washability and poor light fastness of the textile in the dyeing process, and provides the preparation method for the dye carrier, and the prepared carrier can be simultaneously attached with inorganic dye and organic dye and has wide application range.

The technical scheme is as follows: the carrier for attaching the dye comprises a first component and a second component, wherein the first component at least comprises one or more of modified kaolinite, alumina and talcum powder; the second component comprises one or more of sodium alginate, chitosan and polyvinyl alcohol; the mass ratio of the first component to the second component is 20-50: 1.

further, the first component also comprises alumina and talcum powder.

Further, the first component comprises modified kaolinite, alumina and talcum powder in a mass ratio of 10:1: 2-3.

Further, the second component comprises sodium alginate, chitosan and polyvinyl alcohol in a mass ratio of 2:2: 1.

Further, the modified kaolinite is obtained by mixing kaolinite and 0.01-0.1mol/L sodium hydroxide aqueous solution for 2-3h, washing with clear water and drying.

Further, the particle diameter of the alumina is 10-50 nm.

The preparation method of the carrier for attaching the dye comprises the following steps: (1) immersing the kaolinite in 0.01-0.1mol/L sodium hydroxide aqueous solution, washing with clear water after 2-3h, and airing to obtain modified kaolinite for later use; (2) selecting one or more of sodium alginate, chitosan or polyvinyl alcohol, preparing into water solution with concentration of 0.01-0.1g/ml, performing ultrasonic treatment, and freeze drying; (3) mixing the second component obtained in the step (2) with the modified kaolinite obtained in the step (1) according to the mass ratio of 1: 20-50, and mixing to obtain the finished product.

Further, in the step (3), the second component and the first component are mixed according to the mass ratio of 1: 20-50 mixing; the first component comprises modified kaolinite, alumina and talc.

Further, the mass ratio of the modified kaolinite to the alumina to the talcum powder is 10:1: 2-3.

Further, in the step (2), the second component comprises sodium alginate, chitosan and polyvinyl alcohol in a mass ratio of 2:2: 1.

Further, in the step (2), the molecular weight of sodium alginate, chitosan or polyvinyl alcohol is 10000-.

Further, in the step (2), the ultrasonic treatment is performed under the conditions that the ultrasonic power is 20-50Kw and the ultrasonic time is 10-20 min.

Further, the particle size of the alumina is 10-50 nm.

Has the advantages that: (1) the invention changes the surface property of the kaolinite by modifying the kaolinite, and has better adhesiveness to dyes; (2) the invention provides a carrier capable of loading inorganic dye and organic dye by screening the carrier of the dye.
