Problems solved by technology

This dyeing method belongs to the two-bath two-step dyeing process, and the main disadvantages are that the dyeing process is long, time-consuming, and inconvenient for color matching.
If one-bath and one-step dyeing with direct dyes is used, although the process is short, soybean fiber and tencel can also be dyed, but the dyeing result is that the apparent dyeing depth of tencel is significantly higher than that of soybean fiber, and it is washable and moisture-resistant Rubbing fastness is very poor, can not reach level 3, can not meet the requirements of taking
If the one-bath one-step reactive dye dyeing method is used, it will be particularly beneficial to shorten the dyeing process, save dyeing time, and the color matching is also very convenient. However, if the conventional reactive dye dyeing technology is used, the same color of soybean fiber and Tencel is poor, which is still natural. The apparent dyeing depth of silk is higher than that of soybean fiber

Embodiment 1

[0020] The present embodiment selects soybean fiber / tencel interwoven fabric to carry out dyeing treatment, and concrete steps are as follows:

[0021] (1) Cationic modified liquid treatment

[0022] The formula of the cationic modification liquid is as follows: the cationic modifier is darkening agent T, the dosage is 5g / L, the dosage of soda ash is 2g / L, and the bath ratio is 1:30; after the modification liquid is prepared at room temperature, soybean Put the knitted fabric interwoven with fiber and Tencel 1:1 into it, treat it at room temperature for 5 minutes, then raise the temperature to 60°C at a heating rate of 2°C / min, and treat it at 60°C for 30 minutes; after modification, use a concentration of 0.5g / L of non-ionic polyoxyethylene ether compound (Pingping plus 0) solution for washing for 10min.

[0023] (2) Dyeing with reactive dyes

[0024] The soybean fiber / tencel interwoven fabric treated with the above-mentioned cationic modification solution was dyed with Ev...

Embodiment 2

[0030] What this embodiment selects is soybean fiber / tencel interwoven knitted fabric, and it is woven by the soybean fiber yarn of 32 British counts and the tencel yarn of 32 British counts, and the raw material weight ratio is 50:50.

[0031] The formula of the cationic modification solution is as follows: the cationic modifier of the quaternary ammonium compound containing epoxy groups is the color-fixing crosslinking agent DE, the dosage is 2.5g / L, the dosage of soda ash is 2g / L, and the liquor ratio is 1:30. Prepare the modified solution at room temperature, put in soybean fiber / tencel interwoven fabric, treat at room temperature for 5 minutes, heat up to 50°C within 15 minutes, treat at 50°C for 20 minutes, and then use non-ionic polyoxyethylene ether with a concentration of 0.5g / L The compound (Pingping plus 0) solution was washed for 10 minutes.

[0032] Soybean fiber / tencel interwoven fabrics were treated with modifiers and dyed with Everzol Orange 3R, Everzol Red 3BS...

Abstract

The invention relates to a dyeing method for soybean fiber / natural silk blended intertexture, which comprises: taking modification treatment to the blended intertexture with modifying liquid contained soda and cation modifier of quaternary ammonium compound with epoxy radical; adding non-ion polyoxyethylene ether compound as dye leveller into dyeing liquid; taking dyeing process with vinyl sulfone dyestuff or reactive dyes contained opposite radicals; then, clearing and completing the concolore bath dyeing. This invention cuts process and time, saves energy and cost, and improves performance of the product.

Description

technical field [0001] The invention relates to a method for same-color dyeing of soybean fiber / tencel blended fabric, belonging to textile dyeing and finishing [0002] technology field. Background technique [0003] Soybean fiber is a new type of chemical fiber developed by Chinese scientific and technological personnel. It is wet-spun from a mixture of soybean protein and polyvinyl alcohol, and has undergone acetalization and cross-linking treatment in the post-spinning process. Soybean fiber can be blended or interwoven with conventional textile materials such as wool, cashmere, silk, viscose, bamboo fiber, Tencel, Modal, polyester, and nylon. Because soybean fiber has excellent properties such as good moisture absorption and moisture conductivity, soft hand feeling, soft luster, and comfortable wearing, soybean fiber has been used by many textile enterprises to develop new clothing fabrics and home textiles, among which blended and interwoven k...
