Embodiment 1

[0020] A method for dyeing silk with vegetable dyes includes the following steps:

[0021] (1) Degumming cleaning: Heat the degummed silk water bath to 39°C for 4 minutes, add a 10.5% dilute hydrochloric acid solution with water quality to the water bath, and increase the temperature of the water bath to 67°C for 26 minutes, and then add NaOH to the water bath Adjust the solution to pH8, adjust the temperature of the water bath to 53°C for 19 minutes, remove the residual sericin, reduce the content of sericin in the silk, and prevent the discoloration of the silk caused by the dissolution of the sericin, and then add 7% of its water quality to the water bath for cleaning The soaking liquid, which contains citric acid, white vinegar and lemon oil, has a washing effect and can clear the sericin adhering to the silk fibroin. The bactericidal and washing ingredients contained in the elm extract and ginger juice extract can improve the inhibition of silk For bacteria and cleanliness, ...

Embodiment 2

[0034] A method for dyeing silk with vegetable dyes includes the following steps:

[0035] (1) Degumming cleaning: Heat the degummed silk water bath to 38℃ for 3.5min, add the dilute hydrochloric acid solution of 9.5% water mass to the water bath, and increase the temperature of the water bath to 66℃ for 25min, then add it to the water bath Adjust the solution with NaOH solution to pH 7.5, adjust the temperature of the water bath to 52 ℃ for 17 minutes, remove the residual sericin, reduce the content of sericin in the silk, prevent the dissolution of the sericin and cause the silk to fade, and then add its water quality to the water bath 6.8 % Of the cleaning soaking liquid, which contains citric acid, white vinegar and lemon oil and other ingredients has a washing effect, can clearly adhere to the silk fibroin sericin, while the elm tree extract and ginger juice extract contain the sterilization and cleaning components that can improve For the antibacterial and cleanliness of th...

Abstract

The invention discloses a method for dyeing silk vegetable dye. The method comprises the following steps: (1) degumming and washing, executing the secondary degumming treatment to the degummed silk by using diluted hydrochloric acid solution and sodium hydroxide solution, and washing by using washing soaking solution; (2) drying, drying the silk until the moisture content is 11%-14%; (3) dyeing the silk, executing the dyeing treatment to the silk by using a mordant and dyeing solution, and alternately and circularly dyeing for 2-3 times; (4) heating-fixation, treating the dyed silk by using the high-temperature and low-temperature alternated fixation; and (5) drying: drying the fixation silk in the low temperature until the moisture content is 4%-6%. The method for dyeing the silk vegetable dye has the high dyeing efficiency, the dyeing defect proportion is reduced by 3.52%, the fixation effect is good, the color fading is not easy, and the color uniformity is good.

Description

Technical field [0001] The invention belongs to the technical field of silk processing, and specifically relates to a method for dyeing silk with vegetable dyes. Background technique [0002] Botanical dyes are made by extracting pigment components from plants. They are natural, environmentally friendly and highly safe. The botanical dyes that have been extracted include indigo, madder (red), sophora japonica, turmeric (yellow), and There are many kinds of colors such as purple, brown and black. The fabric dyed with vegetable dyes has natural color and does not fade for a long time, and the extracted pigment contains bactericidal and insecticidal components, which can improve the insecticidal and bactericidal properties of the fabric, which is not available in chemical dyes; because of vegetable dyes Without any chemical additives, it is safe to use and has no skin irritation. It is mostly used for children, bedding, underwear, and high-end clothing products. In the dyeing of s...
