Keratin-base bamboo charcoal modified dye powder and method for preparing same

Abstract

The invention provides keratin-base bamboo charcoal modified dye powder and a method for preparing the same. The method includes steps of boiling and softening bamboo chips in alkali liquor, then sufficiently cleaning the bamboo chips, placing the bamboo chips in pectinase solution, carrying out vibration enzymatic hydrolysis to obtain partially disconnected millimeter-level porous bamboo chip primary products, impregnating the porous bamboo chip primary products in keratin solution, taking out the porous bamboo chip primary products, treating the porous bamboo chip primary products by steam and drying the porous bamboo chip primary products to obtain keratin modified porous bamboo chip primary products; carrying out high-temperature carbonization treatment on the keratin modified porous bamboo chip primary products, carbonizing attached keratin to obtain activated carbon at first, then carbonizing bamboo chips to obtain activated carbon, sufficiently grinding the activated carbon, mixing the activated carbon and dye powder with each other, dropwise adding chitosan cross-linking agent solution into the activated carbon and the dye powder, carrying out ball-milling to deeply transmit the chitosan into spaces between the activated carbon and dye, and deeply transmitting the activated carbon into the dye powder by the aid of cross-linking agents and film-forming agents so as to obtain the keratin-base bamboo charcoal modified dye powder. The bamboo chips are used as raw materials. The keratin-base bamboo charcoal modified dye powder and the method have the advantages that textile fabrics and dye prepared from the keratin-base bamboo charcoal modified dye powder prepared by the aid of the method are high in adhesion, and the dye has gorgeous colors and is good in dyeing property and color fastness.

Description

Technical field [0001] The invention belongs to the technical field of textile materials, and specifically relates to a keratin-based bamboo charcoal modified dye powder and a preparation method thereof. Background technique [0002] Bamboos are tall and arbor-like herbaceous plants. The stems are tall and upright or climbing. Bamboo is a very versatile material. At first, people used bamboo to make blue baskets, sieves, and sieves to build houses, instead of bamboo concrete. Steel, paper made of bamboo pulp, bamboo fiber is also widely used in the textile field. Different types of bamboo have different fiber performance requirements. The average length of bamboo fiber is 2.5mm and the average width is 15μm. Bamboo fiber accounts for 57-64% of the content of bamboo. Bamboo is different from wood. The surface contains a layer of fatty wax, which is easy to be covered. It is saponified by hot alkali, and there are less gums and resins. Therefore, bamboo chips can be easily process...

Problems solved by technology

However, the bamboo charcoal particles prepared at present are all black, so the dyes prepared are mostly dark dyes, which is difficult to apply to all dyes.
