Embodiment

[0017] Acrylic top dyed brown, weighing 120 kg.

[0018] 1. Dye:

[0019] Cationic yellow X-8GL, the dosage is 1.2% of the weight of acrylic top;

[0020] Cationic red X-GRL, the dosage is 0.3% of the weight of the acrylic top;

[0021] Cationic emerald blue GB, the dosage is 0.32% of the weight of the acrylic top.

[0022] 2. Additives:

[0023] Acetic acid, consumption is 2% of acrylic top weight;

[0024] Acrylic leveling agent 1227 (dodecyl dimethyl benzyl ammonium chloride), consumption is 0.3% of acrylic top weight;

[0025] Antistatic agent SN (octadecyl dimethyl nitrate), consumption is 1% of acrylic top weight;

[0026] Bulking agent SF (fatty acid polyoxyethylene ester), consumption is 2% of acrylic top weight;

[0027] Softener ES (formed by emulsification of stearic acid, diethylenetriamine amide, epichlorohydrin and acetic acid), the dosage is 2% of the weight of the acrylic wool top.

[0028] 3. Dyeing equipment: top dyeing machine N371.

Abstract

The invention relates to a dyeing process for acrylic wool top, wherein cationic dye is used in acrylic wool top dyeing. The process includes adequately immersing after the wool top is added into the machine, adding acetic acid and levelling agent 1227 at the temperature of 25 DEG C., operating for 5 minutes; adding adequately dissolved cationic dye and operating for 5 minutes; heating to 85 DEG C. and keeping the temperature for 30 minutes; heating to 98 DEG C. according to the speed of 1 DEG C./1 minute; cooling down to 85 DEG C., adding finishing auxiliaries (an antistatic agent SN, a softening agent ES, a leavening agent SF), operating for 30 minutes, taking out. The invention has advantages that (1) hardness in modified terylene wool top dyeing is effectively solved; (2) problem of color spot easiness in prior process is solved by utilizing low temperature coloring characteristic of the modified terylene; (3) problem of bad spinnability of wool top is solved by utilizing characteristic of modified terylene vitrification at low temperature and modifying the process.

Description

technical field [0001] The invention relates to a fiber dyeing process in the textile field, in particular to a dyeing process for acrylic wool tops. Background technique [0002] Traditional acrylic dyeing mostly focuses on hank yarn dyeing and loose fiber dyeing, and there are relatively mature dyeing processes at present. However, the dyeing of acrylic wool tops has always been blank, mainly because of the problems of colored flowers, hard wool tops, difficulty in drying during rewashing, extremely poor spinnability, and excessive consumption. Adapting to market demand is the direction of product development, and acrylic wool top dyeing is an indispensable key technical link in the wool spinning field to meet the needs of product diversification and high-end development, such as the multi-color multi-strand multi-functional wool created by our company The technological requirements must be dyed with acrylic tops. Therefore, it is necessary to break through the difficult...
