Problems solved by technology

Among them, the dyeing method using chemical synthetic dyes, due to the coloring requirements of chemical dyes, requires high temperatures above 90°C during the dyeing process, which consumes a lot of energy, and because chemical synthetic dyes usually contain harmful substances, it will make the dyeing process Seriously polluted and dyed mulberry silk may also have adverse effects on human health
However, the traditional vegetable dyeing method using vegetable dyes also has many problems such as low color fastness, insufficient color and color system, and insufficient supply.

Embodiment 1

[0023] The present embodiment provides a kind of method that mulberry silk is dyed, and this method comprises the steps:

[0024] a, wetting and modifying mulberry silk;

[0025] b, dyeing the mulberry silk obtained through the treatment in step a;

[0026] c, washing the mulberry silk obtained through the treatment in step b;

[0027] d, further fixing the color of the mulberry silk obtained by washing in step c;

[0028] e, softening the mulberry silk after color fixing in step d and directly drying.

[0029] Specifically, step a includes: putting mulberry silk into a dyeing vat, adding soft water (20-25°C) at normal temperature and a treatment agent (Vege Plus) at a concentration of 10% o.w.f. In the aqueous solution of the dye, the temperature in the dye vat was raised from room temperature to 70°C at a rate of +2°C / min for 60 minutes, after which the dye vat was emptied and the mulberry silk was washed with soft water.

[0030] Step b includes: preparing a dye solutio...

Abstract

The invention discloses a dyeing method of mulberry silk. The dyeing method comprises the following steps: a, wetting and modifying the mulberry silk; b, immersing the mulberry silk treated in the step a into a dye solution, and then performing temperature regulation treatment to enable the mulberry silk to absorb the dye solution and fix the color to the mulberry silk; c, washing the mulberry silk treated in the step b; and d, fixing the color of the mulberry silk treated in the step c by using a color fixing agent, wherein the dye solution comprises 0.1-5% o. w. f. of a plant dye, 0.5-2% o.w. f. of a mordant, and the plant dye being a tobacco leaf and stem extract. The dyeing method of the mulberry silk has the advantages of environmental protection, energy saving, good dyeing effect and the like.

Description

technical field [0001] The invention relates to a method for dyeing mulberry silk, in particular to a method for dyeing mulberry silk with plant dyes containing extracts of tobacco leaves and stems. Background technique [0002] Most of the mulberry silk products currently on the market need to be dyed to obtain other colors. Commonly used dyeing methods include the use of chemically synthesized dyes and the use of vegetable dyes. Among them, the dyeing method using chemical synthetic dyes, due to the coloring requirements of chemical dyes, requires high temperatures above 90°C during the dyeing process, which consumes a lot of energy, and because chemical synthetic dyes usually contain harmful substances, it will make the dyeing process Seriously polluted and dyed mulberry silk may also have adverse effects on human health. The traditional vegetable dyeing method using vegetable dyes also has many problems such as low color fastness, insufficient color and color system, a...
