Problems solved by technology

In the hot-melt dyeing of polyester and its blends, the problem of dye migration is very prominent, resulting in the problem of uneven dyeing
In the past, natural polymer substances (such as sodium alginate, pectin, etc.) were often used as anti-swimming agents in China, but they had an impact on the stability of the dye liquor, especially in summer, when the dye liquor was easily deteriorated

Embodiment 1

[0031] 1. In the reaction kettle, add 60 parts of deionized water, 18 parts of methacrylic acid, 15 parts of acrylamide and 2 parts of maleic anhydride, stir and dissolve, and adjust the pH value to 6.5- 7.5, after being down to room temperature, add 3 parts of initiator potassium persulfate solution (the concentration of potassium persulfate solution is 10%) to obtain the reaction solution; get 2 / 3 of the prepared reaction solution and add it to another thermometer equipped with a thermometer. In the reaction kettle, heat it to 85-95°C under stirring, keep it warm for 30 minutes, then add the remaining reaction solution dropwise, and finish the dropwise addition in about 1 hour. Continue to keep warm at the same temperature for 2 hours. After the reaction, cool to room temperature. The obtained reaction product is component A, which has a viscous liquid appearance and a pH value of 6.5-7.5.

Abstract

The invention discloses an environment-friendly migration inhibitor which consists of a component A and a component B, wherein the mass of the component B accounts for 1-2% of the total mass of the migration inhibitor; the component A is a product prepared from methacrylic acid, acrylamide and cis-butenedioic anhydride in an addition manner; the component B is a mixture prepared from CMC and sodium alginate in a mixing manner. The environment-friendly migration inhibitor disclosed by the invention has a network-shaped macromolecule structure and has certain computability adsorption with polyester, gelatinization adsorption can be achieved easily, and migration of polyester and fabrics of polyester in the long-machine dyeing process can be avoided. The environment-friendly migration inhibitor disclosed by the invention is good in migration inhibition property, nonpoisonous and pollution-free, easy to degrade and good in environmental friendliness, and the amount of the environment-friendly migration inhibitor is reduced by 10% in production when compared with that of the prior art.

Description

1. Technical field [0001] The invention relates to an environment-friendly anti-migration agent and a preparation method thereof, so as to overcome the problem of dyeing migration of polyester and its blended fabrics in the continuous pad dyeing process. 2. Background technology [0002] The dyeing performance of polyester is poor, and generally it must be dyed with disperse dyes at high temperature or in the presence of a carrier. In the hot-melt dyeing of polyester and its blends, the problem of dye migration is very prominent, resulting in uneven dyeing. In the past, natural polymer substances (such as sodium alginate, pectin, etc.) were often used as anti-swimming agents in China, but they had an impact on the stability of the dye liquor, especially in summer, and the dye liquor was prone to deterioration. [0003] Therefore, it is particularly important to develop an anti-swimming agent that has good compatibility with dyes and auxiliaries, can improve the stability of...
