Problems solved by technology

[0005] At present, the method to solve the back dyeing problem of denim is to add a suitable anti-staining agent in the treatment solution. The existing anti-staining agents are mainly divided into anionic surfactants and cationic surfactants, anionic surfactants and cationic surfactants. Type surfactants can form complexes with proteins and destroy the structure of proteins, inactivate proteins (cellulase), greatly reducing the anti-backstaining effect of anti-staining agents

Embodiment 1

[0043] The preparation method of a kind of anti -dye -washing agent of denim clothing is as follows:

[0044] (1) Preparation of polyether dual carboxylic acid A1:

[0045] In the reactor with a temperature of 80 ° C, add 2L of 2L, and the average phenyl acid anhydride 2.18kg and the average molecular weight of a polyethylene monotolin 10kg are added to the reactor.The constant temperature reaction is then for 6 hours under 100 ° C, and polyether dilateral carboxylic acid A1 is made.

[0046] (2) Preparation of anti -dye C1:

[0047] Polyether dilateral carboxylic acid A1 12.18kg, ethylene glycol 62g, sulfate di ethyl 1.3g of esterization reactions, the constant temperature reaction at 100 ° C for 60 minutes, and then heated to the esterization response at 180 ° C.When it reaches 17.5g, the reaction is over.Then perform decompression and distillation at this temperature for 1 hour, and the dyshane is completely removed from the reactor to obtain the anti -infected agent C1, that i...

Embodiment 2

[0050] The preparation method of a kind of anti -dye -washing agent of denim clothing is as follows:

[0051] (1) Preparation of polyether dual carboxylic acid A2:

[0052] In the reactor with a temperature of 85 ° C, adding 2.5L of dyshane is added, and the average phenyl acid anhydride 2.18kg and the average molecular weight of the average molecular weight of 1000 are added to the reactor with 20kg, and the mixing is mixed evenly.The constant temperature reaction is then for 5.5 hours under 100 ° C, and polyether dilateral carboxylic acid A2 is made.

[0053] (2) Preparation of anti -dye C2:

[0054] Polyettic dilateral carboxylic acid A2 22.18kg, ethylene glycol 62g, a esterization reaction to toluene sulfonic acid 2.3g, 50 minutes of constant temperature reaction at 100 ° C, and then increased to the esterization response at 170 ° C.Reaching 17.2g, the reaction is over.Then reducing decompression and distillation at this temperature for 2.5 hours, and the dyshane was completel...

Embodiment 3

[0057] The preparation method of a kind of anti -dye -washing agent of denim clothing is as follows:

[0058] (1) Preparation of polyether dual carboxylic acid A3:

[0059] In the reactor with a temperature of 90 ° C, add 2 methane 3L, and the average phenyl acid anhydride 2.18kg and the average molecular weight of a polyethylene glycol monoethyl ether 40kg are added to the reactor.The constant temperature reaction was then made at 100 ° C for 3.5 hours, and the polyether dilateral carboxylic acid A3 was made.

[0060] (2) Preparation of anti -dye C3:

[0061]Polyettic dilateral carboxylic acid A3 42.18kg, ethylene glycol 62g, and 5.0g of hydrochloric acid permeate the esterization reaction. The constant temperature reaction is 40 minutes under 100 ° C conditions, and then the esterization reaction is 2.5 hours at the condition of the temperature at 160 ° C., The reaction is over.Then reducing decompression and distillation at this temperature for 2.5 hours, and the dyshane was co...

Abstract

The invention relates to the technical field of a reserving agent for washing, particular to the reserving agent for washing jean garments and a preparation method thereof. The reserving agent is generated by carrying out esterification reaction on polyether dicarboxylic acid and ethylene glycol serving as raw materials under the action of an acid catalyst, wherein the molar ratio of the polyether dicarboxylic acid and the ethylene glycol is 1:1; and the reserving agent is water-solubility macromolecule polyester. The reserving agent provided by the invention is a non-ionic surface active agent and is not combined with protein in the washing and fade-out treatment process of the jean garments, and therefore, the catalytic activity of the reserving agent can be remained, and the reserving effect has excellent back-staining resistant effect. The preparation method provided by the invention is simple in production process, is convenient for realizing large-scale production and has good production prospect and market application prospect.

Description

Technical field [0001] The present invention involves the field of washing anti -dye technology, and specially involves a kind of anti -dye and preparation method for denim clothing washing. Background technique [0002] Cowboy clothes have long been loved by consumers with their solid and durable performance and natural appearance.Especially in recent years, with the increasingly strong mentality of people's return, denim clothes are not only loved by generations. It is loved by people of all ages with its unique charm. [0003] When making denim clothes in denim cloth, it usually needs to be returned to the old to remove some dyes to achieve the natural appearance, and at the same time, it also gives the fabric unique style.The return of denim fabrics is to use fibrobinase to control the controllable cellulose fiber to control, so that some fibers dissolve.Essence [0004] However, during the washing process, the blue dye will be returned from the water solution to the dyeing o...
