Embodiment 1

[0030] A method for improving color fastness by blending multiple dyes, comprising the following steps:

[0031] S1. Mix and stir the multi-dye evenly, the dye concentration is 3.2% owf;

[0032] S2. Add dispersant N 0.2g / L, acrylic acid / maleic acid coordination polymer sodium salt 1g / L, graphene oxide 0.1g / L in step S1;

[0033] S3. dyeing the cotton cloth according to the liquor ratio of 1:5;

[0034] Wherein, the multi-dye in step S1 includes: two or three of red dye, yellow dye, and blue dye; the red dye is cochineal extract; the yellow dye is gardenia extract; the blue The color dye is blueberry extract. In the step S3, the dyeing temperature is 120° C., and the dyeing time is 45 minutes. After the dyeing is completed, it is washed with water and dried.

Embodiment 2

Abstract

The invention belongs to the technical field of fabric dyeing, and particularly relates to a method for improving color fastness through multi-dye blending. The method comprises the following steps ofS1, preparing dye liquor; S2, immersing polyester cotton according to the bath ratio of 1:(10-40); S3, performing heating to 90-100 DEG C at the heating rate of 3-4 DEG C / min, keeping the temperaturefor 10-20 minutes, performing heating to 110-120 DEG C at the heating rate of 0.5-2 DEG C / min, keeping the temperature for 5-15 minutes, performing heating to 130-145 DEG C at the heating rate of 0.5-1.5 DEG C / min, and keeping the temperature for 40-50 minutes; and S4, carrying out water washing, soaping and drying treatment. According to the invention, dyeing of two kinds of fibers is realized in one bath, the steps of reduction cleaning and post-treatment are omitted, the production efficiency is greatly improved, and the consumption of water resources and other energy sources is greatly reduced. Moreover, obtained cloth has higher light fastness and washing fastness, and dyeing is more uniform.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing, and in particular relates to a method for improving color fastness by blending multiple dyes. [0002] technical background [0003] The basic colors that cannot be decomposed in the color are called primary colors, and the primary colors can be synthesized into other colors. Usually, the three primary colors are red, green, and blue, and the three primary colors can be mixed to produce all colors. [0004] In recent years, with the enhancement of people's awareness of environmental protection, they have gradually realized that chemically synthesized dyes will cause serious damage and destruction to human health and the environment. Plant dyes refer to the use of natural flowers, grasses, trees, stems, leaves, fruits, seeds, bark, and roots to extract pigments as dyes. Plant dyes are non-toxic and harmless, and will not cause any harm to human health; the dyed fabrics are natural in color a...
