Problems solved by technology

[0002] At present, direct dyes can dye cellulose and silk fabrics, but the application of 29 direct dyes is subject to export restrictions due to poor light color and soaping fastness, especially due to environmental protection factors.
Reactive dyes can dye protein and cellulose fabrics. Some printing and dyeing workers gradually replace direct dyes with reactive dyes. However, the process conditions, equipment conditions, and raw material preparations of reactive dyes are far from those of direct dyes. Not every factory All can be replaced in one step, and the reactive dyes are expensive and the process conditions are harsh

Embodiment 1

[0030] The feeding ratio of silk fibroin and tetraethyl orthosilicate in the nano-sol is SF: TEOS=7: 3, the sum of the mass percentage concentration of silk fibroin and silicon dioxide is 5%, the coated fabric is nylon fabric, dyestuff It is cationic red SD-GRL.

[0031] (1) Coating treatment: The fabric is dipped and rolled twice in the silk fibroin / silica nano-sol finishing solution, and the pressure is set to 3kgf / cm 2 , The liquid-carrying rate is 70%. Then the fabric was dried in a blast oven at 60°C, and then the fabric was put into 75% methanol solution for 15 minutes, and the fabric was taken out for pre-drying (60°C, 20min), baked (120°C, 3min), and finally Wash and dry.

[0032] (2) Pre-dyeing treatment: Wet the coated fabric and configure a cationic dye solution. The cationic dye is 2.0% of the weight of the dyed object, the bath ratio is 1:100, and the pH value of the dye solution is adjusted to 6.8.

[0033] (3) Dyeing treatment: cationic dye dyeing process: pu...

Embodiment 2

[0036] The feeding ratio of silk fibroin and tetraethyl orthosilicate in the nano-sol is SF: TEOS=5: 5, the mass fraction of the sum of silk fibroin and silicon dioxide is 6%, the coated fabric is cotton fabric, and the dyestuff is Acid red GSF.

[0037] (1) Coating treatment: the fabric is dipped and rolled twice in silk fibroin / silica nano-sol finishing solution with a pressure of 3kgf / cm 2 , The liquid-carrying rate is 70%. Then the fabric was dried in a blast oven at 60°C, and then the fabric was placed in a 70% methanol solution for 20 minutes, and the fabric was taken out for pre-drying (55°C, 20min), baked (150°C, 2min), and finally washed with water After drying.

[0038] (2) Pre-dyeing treatment: Wet the coated fabric and prepare an acid dye solution. The acid dye is 1.0% of the weight of the dyed object, the bath ratio is 1:50, and the pH of the solution is adjusted to 2.6 with acetic acid.

[0039] (3) Dyeing treatment: Put the coated fabric to be dyed into the a...

Abstract

The invention relates to a method for dying the fabric with fibroin coat, which utilizes the cation dye and acid dye to dye the rear cotton, nylone and terylene. The inventive method comprises that 1, treating the coat that furnishing the fabric in fibroin/silicon dioxide nanometer sol, drying at 40-80Deg. C, treating with methanol and drying, baking at 100-150Deg. C for several minutes, washing in water and drying; 2, pretreatment before dying comprises that 1, wetting the fabric and preparing the anion dye which is 0.1-2.0% of object mass, while the bath ratio is 1:50-1:100, and using acetate to adjust the pH value to 4.0-8.0; 2, wetting the fabric and preparing the acid dye at 0.1-2.0% of object mass, while the bath ration is 1:50-1:100, using acetate to adjust the pH value to 2.0-3.5; 3, dying process comprises that 1, dying with anion, 2, dying with acid dye; 4, drying and ironing the object. The invention has simple process, dye-uptake and high color stability, without other agents and pollution, but high economic and social benefits.

Description

technical field [0001] The invention belongs to the field of textile dyes, in particular to a method for dyeing silk fibroin-coated fabrics. Background technique [0002] At present, direct dyes can dye cellulose and silk fabrics, but the application of 29 direct dyes is subject to export restrictions due to poor light color and poor soaping fastness, especially due to environmental protection factors. Reactive dyes can dye protein and cellulose fabrics. Some printing and dyeing workers gradually replace direct dyes with reactive dyes. However, the process conditions, equipment conditions, and raw material preparations of reactive dyes are far from those of direct dyes. Not every factory All can be replaced in one step, and the reactive dyes are expensive and the process conditions are harsh. Acid dyes and cationic dyes are not only cheaper than reactive dyes, but also have more varieties and bright colors, and the process equipment and process conditions are similar to tho...
