Problems solved by technology

However, in the traditional dyeing process, when the acid agent is added, it is easy to accelerate the instant dyeing and cause the problem of color flower, and this problem has long plagued the nylon fabric dyeing and finishing factory; at the same time, the addition of glacial acetic acid makes the dye The low pH will make the dye color quickly, so that the dyeing of weak acid dye can only be controlled by slowly heating up at 0.5°C / min during the dyeing process, which will make the entire dyeing process take a long time

preparation example Construction

[0017] The preparation method of the described a kind of nylon fast dyeing and leveling agent is realized according to the following steps: 1) fully stir and mix 40-50% ethylene glycol dicarboxylate and 5-10% ethylene glycol; obtain the mixture ; 2) Add 20-30% of stearylamine polyoxyethylene ether and 15-20% of Tween-80 into the mixture in turn, and stir and mix together to obtain nylon quick dyeing and leveling agent.

[0018] A kind of quick dyeing and leveling agent for nylon of the present invention, at first, though ethylene glycol dicarboxylate is weakly acidic at normal temperature, but the pH value is close to 7, can effectively prevent weakly acidic dyes from being dyed at low temperature, and has It is conducive to the slow dyeing of weak acid dyes, so the dyeing of weak acid dyes can be controlled by 2-3°C / min. rapid temperature rise during the dyeing process, which greatly shortens the entire dyeing process time; With the gradual increase of dyeing temperature, eth...

Abstract

The invention discloses a nylon rapid-dyeing color-homogenizing agent. The nylon rapid-dyeing color-homogenizing agent is prepared from the following raw materials in weight percentage: 40-50% of ethylene glycol diformate, 5-10% of ethylene glycol, 20-30% of octadecylamine polyoxyethylene ether and 15-20% of tween-80. The nylon rapid-dyeing color-homogenizing agent can keep the dye liquid to have high pH value at below 70 DEG C in use, can effectively prevent weak acid dyes from dyeing at low temperature, is beneficial to slowly dyeing of the weak acid dyes, can greatly reduce the whole dyeing process time, has excellent acid-release effect when the dye liquid is at above 70 DEG C, can enable the weak acid dyes and polyarmide fiber to be combined firmly, has excellent slowly-dyeing effect, solves the problem of dyeing defect caused by instant dyeing in the traditional nylon dyeing technique process, and can improve the dyeing rate of dyes; all components are environment-friendly products and meet the requirements of Okeo-Tex Standard 100 of the European union and the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and specifically refers to a color leveling agent (also known as a leveling agent) specially used in the rapid dyeing process of nylon. Background technique [0002] Nylon (Nylon) is the common name of polyamide (Polyamide), also known as nylon, referred to as PA. The composition and structure of polyamide fibers have similar characteristics to protein structures, that is, there are amino and carboxyl groups on the molecular chain, but the amino and carboxyl groups of polyamide fibers only exist at the end of the molecular chain, and the content is low, so it is also called Terminal amino group and terminal carboxyl group, the content of terminal carboxyl group in polyamide fiber is higher than that of terminal amino group. At the same time, there are a large number of amide groups in the middle of the molecular chain. Due to the above characteristics, when the polyamide fib...
