Problems solved by technology

However, there are many problems in the practical application of plant indigo, such as poor color fastness to washing, rubbing, and light, and it is difficult to industrialize and standardize production.
[0004] Silk is the lightest, softest and thinnest natural fiber in nature. Acid dyes and neutral dyes are mainly used for dyeing silk fabrics. Acid dyes have a complete spectrum and bright shades, but their color fastness is poor, especially the wet fastness. Neutral dyes have better color fastness than acid dyes, but have less vividness in their color spectrum

Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0017] A kind of dyeing process of indigo dyed silk fabric, process is as follows:

[0018] (1) Put the silk fabric in an aqueous solution dissolved in sodium carbonate at a concentration of 5g / L, a bath ratio of 1:50, a temperature of 90°C, and a time of 30 minutes, then take out the silk fabric and wash it with water at 60°C for 5 minutes.

[0019] (2) Put the silk fabric into a solution in which acid protease is dissolved, the concentration is 5g / L, the liquor ratio is 1:30, the pH value is 6, the temperature is 40°C, and the time is 30min.

[0020] (3) Soak the silk fabric after enzyme treatment in 0.5g / L sodium lauryl sulfate, 5g / L ethanol, 10g / L sodium hydroxide, 20g / L glucose, 20g...

Abstract

The invention relates to a dyeing process of indigo dyed silk fabrics, which comprises the following steps: (1) placing the silk fabrics in an aqueous solution in which an alkali agent is dissolved for pretreatment. (2) placing the pretreated silk fabric in a protease solution for enzyme treatment. (3) Soak the silk fabric after the enzyme treatment in the dye material liquid that is configured with dispersant, dye cosolvent, alkali agent, reducing agent, acid agent, antioxidant, anti-over-reducing agent, leveling agent and dye it. The dyed silk fabric is washed and dried to obtain the dyed silk fabric. The invention adopts pretreatment and enzyme treatment for dyeing, which can make the dyeing effect uniform, and endow the fabric with better dyeing rate, abrasion fastness and washing fastness. The indigo dyeing method of the invention is convenient for automatic operation, has a good working environment and stable hue, and improves the competitiveness of products in the market.

Description

technical field [0001] The invention belongs to the technical field of finishing and dyeing of textile materials, and relates to a dyeing process of indigo dyed silk fabrics. Background technique [0002] Chemical dyes have gradually replaced the application of natural dyes in fabric dyeing due to their rich color and excellent color fastness. However, the problem with chemical dyeing methods is that dyes may cause serious water pollution after dyeing textiles, and the chemical dye residues after dyeing can directly contact the skin, which may bring dermatitis, allergies and carcinogenicity to the skin. [0003] The textiles produced by plant indigo dyeing are safe for the human body and the environment. Generally, they are Chinese herbal medicines with certain curative effects. While dyeing, they can endow the fabric with certain health care functions, such as natural fragrance, heat clearing, cooling blood, detoxification, refreshing and brain strengthening. Therefore, it...
