Embodiment 1

[0033] Pre-treatment: Accurately weigh 10 grams of silkworm chrysalis protein and acrylonitrile graft copolymerized fiber, 1:50 by bath ratio, 500 grams of water, add 4 grams per liter of hydrogen peroxide (30%), 4 grams per liter of sodium silicate as a stabilizer, Use sodium carbonate to adjust the pH value to 9, raise the temperature to 50°C, oxygen bleach for 2 hours, and finally wash twice with water at 40°C, dehydrate, and dry for dyeing.

[0034] Take 10 grams of the above fiber, bath ratio 1:50, prepare 500 dyeing liquor, add acetic acid to adjust the pH value to 4, special DCP leveling agent 3 grams per liter, cationic dye (malachite green) 2%; dyeing temperature 100 ° C , dyeing time 50 minutes. The specific dyeing process is as follows:

[0035] The initial dyeing temperature is 40°C, the dyeing heating rate is 1°C / min, the temperature is raised to 100°C, and the temperature is kept for 50 minutes, then the temperature is lowered at a rate of 2°C / min, and the liqui...

Embodiment 2

[0037] The dyestuff adopts cationic yellow 4G3%, and the DCP leveling agent consumption is 5 grams per liter, and other parameters are the same as example 1. After testing, the wet rubbing fastness of the dyed finished product is grade 4, and the soaping fastness is grade 4.

Embodiment 3

[0039] DCP leveling agent configuration.

[0040] Formula (mass percentage):

[0041] C 12 ~C 18 Alkyl dimethyl benzyl ammonium chloride (chemical pure) 45%

[0042] Fatty alcohol polyoxyethylene (20-35) ether (chemically pure) 15%

[0043] Sorbitan fatty acid ester (C 11 h 23 COOC 6 h 8 (OH) 5 ) (chemically pure)

[0044] 12%

[0045] water 28%

[0046] Stir and mix in a container with a stirrer for 60 minutes, and let stand without stratification.

Abstract

The invention relates to a dyeing method for silkworm chrysalis protein and propylene graft copolymerization fiber, and its characteristic: adopting positive ion dye to dye them on the condition of adding DCP level dyeing agent, where the components of the level dyeing agent: C12-C18 alkyl dimethyl benzyl ammonium chloride, fatty alcohol polyoxyethylene (20-35), sorbitol fatty acid ester (C11H23COOC6H8(OH)5) and water. Before dyeing, it uses oxydol to bleach the fiber. The dyeing method is simple and the finished product has good homochromy and chroma.

Description

technical field [0001] The invention relates to a dyeing method in the field of textile printing and dyeing production, in particular to a method for dyeing silkworm chrysalis protein and acrylonitrile graft copolymerized fibers with cationic dyes. Background technique [0002] Silkworm chrysalis protein and acrylonitrile graft copolymerization fiber contains natural polymer compound (silkworm chrysalis protein) and synthetic fiber component (polyacrylonitrile), which makes it have the characteristics of protein fiber hygroscopicity, antistatic property, comfort, etc. and has the characteristics of polyacrylonitrile Its excellent characteristics such as soft hand feeling and good warmth retention make it a new fiber material worthy of promotion and application. [0003] Traditionally, silk and wool are mainly dyed with acid dyes, neutral dyes and other dyes. In recent years, although there are reports related to protein fibers such as silk and wool that adopt cationic dyein...
