Embodiment 1

[0027] (1) The mineral dye azurite is crushed, and the balls are formed into a micronano-scale azurite powder with a particle size of 0.5 μm. The material-liquid ratio is 1g:25ml, and the micro-nano-scale azurite powder is added to the oxalic acid solution , heat and stir at 70°C until dissolved, add 10ml of ammonium salt solution, heat and stir at 75°C for 20min to form natural mineral dyes, wherein the mass fraction of mineral dyes is 0.5%.

[0028] (2) Wash the fresh leaves of the plant dye horse indigo, cut them into pieces with a length of less than 5mm, place them in deionized water with a material-to-liquid ratio of 1g:30ml, adjust the pH value to 3, and adjust the temperature to 50°C. Ultrasonic treatment was performed for 30 min at a power of 500 W, and the filter residue was removed by filtration to obtain a natural vegetable dye, wherein the mass fraction of the vegetable dye was 15%.

Embodiment 3

[0035] (1) The mineral dye azurite is crushed, and the ball is formed into a micronano-scale azurite powder with a particle size of 0.8 μm. The material-liquid ratio is 1g:28ml, and the micro-nano-scale azurite powder is added to the oxalic acid solution , heat and stir at 75°C until dissolved, add 13ml of ammonium salt solution, heat and stir at 78°C for 25min to form natural mineral dyes, wherein the mass fraction of mineral dyes is 0.7%.

[0036] (2) Wash the fresh leaves of the plant dye horse indigo, cut them into pieces with a length of less than 5mm, place them in deionized water at a ratio of 1g to 45ml, adjust the pH value to 4, and adjust the temperature to 55°C. Ultrasonic treatment was performed for 45 minutes at a power of 500 W, and the filter residue was removed by filtration to obtain a natural vegetable dye, wherein the mass fraction of the vegetable dye was 17%.

Abstract

The invention provides dye based on cellulose-based aerogel. The dye contains natural plant dye, natural mineral dye, the cellulose-based aerogel, a thickening agent, a dispersing agent, a pH regulator and a solvent. The preparation method specifically comprises the steps of grinding and crushing azurite as the mineral dye, grinding balls into azurite powder, adding the micro-nano azurite powder to an oxalic acid solution, heating to dissolve, adding to an ammonium salt solution, heating and stirring so as to form the natural mineral dye; cleaning and cutting fresh baphicacanthus cusia into pieces, putting in deionized water, heating to perform ultrasonic treatment, and filtering so as to obtain the natural plant dye; mixing the natural mineral dye with the natural plant dye, adding a surfactant, then adding the cellulose-based aerogel, adjusting a pH value and temperature, homogenizing, stirring, then adding chitosan, and uniformly mixing so as to form the dye based on the cellulose-based aerogel.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a dye based on cellulose-based airgel and a preparation and dyeing method thereof. Background technique [0002] For a long time, our country has done deep research on the dyeing or coating processing of textiles, from mineral colors at the beginning, to plant colors, and even now to synthetic dyes. Among them, natural dyeing comes from nature, is harmless to human health, and is biodegradable. With the concept of green nature becoming popular in recent years, natural dyes have begun to enter people's field of vision and become a research hotspot. [0003] At present, the research on natural dyeing is mostly about natural plant dyes, such as plant raw materials such as madder, sumac, pagoda, comfrey and turmeric. The plant dyes are obtained by ultrasonic wave and solvent extraction, and then treated with rare earth, citric acid and chitosan. Dyeing by equal...
