Acid soaping agent

Abstract

The invention discloses an addition agent acid soaping agent for dyeing. Although the conventional soaping agent composite has good soaping function, but cannot neutralize the alkaline substances which are remained on the cloth, and the cloth is washed by water for multiple times until the pH value of the cloth is close to neutral, the cloth can be used, so a great amount of water resource is wasted. Fatty alcohol polyethenoxy ether is firstly reacted with acrylic acid or maleic acid to generate a polymerization monomer with surface activity, then under the existence of the evocating agent, the polymerization monomer is polymerized with hydrophilic monomer to generate a macromolecular polymer having dispersion chelation performance, and the macromolecular polymer is compounded with the surface active agent to obtain the acid soaping agent. The prepared acid soaping agent integrates the neutralization process and the soaping process after the dyeing of the active dye, so the process flow is greatly shortened, the water is saved, the energy is saved, the emulsion dispersion chelation performance is excellent, the loose color on the texture can be easy to wash, and the staining prevention performance is excellent.

Description

technical field [0001] The invention relates to an auxiliary agent for printing and dyeing, in particular to an acidic soaping agent. Background technique [0002] Due to the mature dyeing process and complete color spectrum of reactive dyes, especially in recent years, a series of dual reactive dyes with high fixation rate have been developed, so their applications are becoming more and more extensive. However, since the reactive dyes will be hydrolyzed while being dyed and fixed, the adsorption of the hydrolyzed dyes on the fibers will seriously affect the color fastness of the dyed products, so the reactive dyes must be soaped after dyeing. The main purpose of soaping is to remove hydrolyzed dyes, unfixed dyes and other impurities attached to the fibers. [0003] There are many kinds of soaping agents on the market. According to different soaping mechanisms, commonly used soaping agents can be divided into surfactants (such as industrial soap powder), chelating (such as ...
