Problems solved by technology

[0010] Although the structure and molecular weight of the polymer prepared by this method can be relatively effectively controlled, most of the reports on the polymer appear in the functional finishing agent and there are very few reports in the pretreatment and dyeing auxiliaries, and most of the prepared white emulsions shape
[0011] In view of the above-mentioned related technologies, the inventor believes that most of the above-mentioned functional monomers are reported to be used for functional finishing. If they are used as soaping agents, their ability to remove floating color and prevent back staining needs to be improved

preparation example 1

[0051] The acrylate polymer is prepared from components comprising the following parts by mass:

[0052]

[0053] Wherein, the aqueous solution of acrylate salt is sodium acrylate aqueous solution, and the preparation method is to neutralize the acrylic acid to pH=8 with sodium hydroxide (32%) aqueous solution. Phenylpropionic acid is 3-phenylpropionic acid and was purchased from Nantong Tianxiang Biological Engineering Co., Ltd.

[0054] The dispersing aid is JFC-2 dispersing agent of Jiangsu Haian Petrochemical Co., Ltd.

[0055] The acrylate monomer was n-butyl acrylate and was purchased from Nantong Runfeng Petrochemical Co., Ltd.

[0056] Maleic anhydride was purchased from Nantong Runfeng Petrochemical Co., Ltd.

[0057] The preparation technology of acrylic polymer specifically comprises the following steps:

[0058] According to parts by mass, put the acrylate monomer and maleic anhydride into the dispersing aid to stir and disperse, raise the temperature of the ...

preparation example 2

[0060] The difference between Preparation Example 2 and Preparation Example 1 is that the dispersing aid is not a conventional commercially available JFC-2 dispersant, and the dispersing aid includes the following components in parts by mass:

[0061] Emulsifier 2kg;

[0062] Slightly soluble magnesium salt or insoluble magnesium salt 5kg;

[0063] 133kg of water.

[0064] Among them, the emulsifier is sodium cumene sulfonate and is purchased from Guangzhou Chuangen Chemical Technology Co., Ltd.; and the slightly soluble or insoluble magnesium salt is magnesium hydroxide.

[0065] The preparation technology of acrylic polymer specifically comprises the following steps:

[0066] S1: According to the mass ratio, the emulsifier and slightly soluble magnesium salt or insoluble magnesium salt are added with water and stirred to disperse to obtain a dispersion;

[0067] S2: According to parts by mass, put the acrylate monomer and maleic anhydride into the dispersion obtained in s...

preparation example 3

[0069] The difference between Preparation Example 3 and Preparation Example 2 is that in the dispersing aid, the emulsifier is a mixture of sodium cumene sulfonate and isomeric decanol polyoxyethylene ether in an equal mass ratio. Isomerized decanol polyoxyethylene ether was purchased from Jiangsu Haian Petrochemical.

Abstract

The invention relates to the field of textile printing and dyeing auxiliaries, and particularly discloses a neutralizing soaping agent. The neutralizing soaping agent comprises the following components in parts by mass of 15-20 parts of an acrylate polymer; 5 to 10 parts of a polyethyleneimine ethoxy compound; 3 to 6 parts of polyacrylic acid; 5 to 10 parts of polymaleic anhydride; 2-5 parts of an anti-agglomeration auxiliary agent; and water supplemented to 100 parts. The soaping agent provided by the invention has good effects of removing surface dye and preventing back staining.

Description

technical field [0001] The application relates to the field of textile printing and dyeing auxiliaries, in particular to a neutralizing soaping agent. Background technique [0002] During the dyeing process, there are many unfixed dyes, hydrolyzed dyes and other chemical auxiliaries in the dyeing solution. After dyeing, these impurities must be washed out to improve the color fastness and brightness of the fabric. The general washing process includes water washing and soaping. Soaping is the process of cleaning unfixed dyes, dyeing aids, printing pastes, etc. on the surface of the fabric under certain conditions with a soaping agent. Due to problems such as dirty washing and re-staining in the soaping process, multiple washings and soapings must be carried out to achieve the desired washing effect. [0003] The more common acrylic polymers in soaping agents are widely used in various dyeing factories. The synthesis methods of such products are roughly divided into the follo...
