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 Highly polluted and dyed cashmere fabrics 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.

Abstract

The invention discloses a dyeing method of cashmere. The dyeing method comprises the following steps:(a) moistening and modifying a cashmere fabric; (b) dyeing the cashmere fabric obtained in the step (a) by using a dyeing solution containing tobacco leaves and stem extracts under the temperature condition of 30-45 DEG C for a time long enough to enable the dyeing solution to be adsorbed on the surface of the cashmere fabric and penetrated in the cashmere fabric, subsequently raising temperature to 65-75 DEG C, and performing heat preservation for a time long enough to enable color to be fixed on the cashmere fabric so that the color of the cashmere fabric is further fixed; (c) washing the cashmere fabric obtained through treatment in the step (b). The dyeing method of the cashmere, disclosed by the invention, has the advantages of environmental protection, energy conservation, good dyeing effect and the like.

Description

technical field [0001] The invention relates to a method for dyeing cashmere fabric, in particular to a method for dyeing cashmere with a dye containing tobacco leaf and stem extracts. Background technique [0002] Cashmere fabric products currently on the market, especially natural cashmere fabric products, are limited by the single color of natural cashmere fabrics, and most of them 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 Cashmere fabrics that are heavily polluted and dyed may also have adverse effects on human health. The traditional vegetable dyeing method ...
