Novel acidic anti-staining soap lotion and preparation method thereof

Abstract

The invention discloses a novel acidic anti-staining soap lotion and a preparation method thereof. The novel acidic anti-staining soap lotion is prepared from aliphatic amine polyoxyethylene ether biquaternary ammonium salt, a maleic anhydride-acrylic acid-N-vinyl pyrrolidone terpolymer, a carboxyalkylthiosuccinic acid and water. The acidic anti-staining soap lotion has extremely strong dispersing and chelating abilities, and has the strong affinity to hydrolyzed reactive dyes and dissociative reactive dyes. When the acidic anti-staining soap lotion is applied to a soaping aftertreatment process of reactive dye dyeing cotton fabrics, the production procedures are reduced, the water consumption is lowered, the dyeing fastness of the fabrics is obviously improved and the good anti-staining effect is realized. Thus, under the same condition, the usage amount of the soap lotion is reduced, so that the damage to fibers is reduced. Therefore, the novel acidic anti-staining soap lotion has high performance-price ratio.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a novel acidic anti-stain soaping agent and a preparation method thereof. Background technique: [0002] Reactive dyes are mainly used for dyeing and printing of cellulose fibers. At the same time of dyeing and fixation, reactive dyes are prone to hydrolysis, low dye utilization rate and serious floating color, which not only affects the color fastness of the fabric, but also easily stains the white background. It is very difficult to remove the floating color, and consumes a lot of energy and water. The soaping process can effectively remove the floating color, ensure the color fastness, make the color light more vivid and pure, and effectively improve and ensure the fixation of the dye. Therefore, the soaping process is one of the key steps for the quality of printing and dyeing products. [0003] Reactive dye soaping agent continues to develop with the ra...

Problems solved by technology

[0004] In the Chinese patent whose publication number is CN102876476A, an acidic soaping agent is disclosed, which consists of carboxyethyl thiosuccinic acid, maleic acid-acrylic acid copolymer, ethylenediamine di-o-hydroxyphenyl acetate and defoamer Compounded, the soaping agent can save one pickling or several water washings, reduce the pressure of sewage treatment, and the maleic acid-acrylic acid copolymer used in it is low-cost, low-foaming, non-toxic and biodegradable, but There is still a considerable difference between its anti-staining property and the ideal

[0005] In the 6th issue of "Journal of Xi'an Polytechnic University" in 2011, "Development and Application of New Acidic Soaping Agent", an acidic soaping agent is introduced, which is composed of maleic anhydride-acrylic acid-N vinylpyrrolidone terpolymer, Compounded with carboxyethylthiosuccinic acid and hydroxyethylidene diphosphonic acid, this acidic soaping agent is used in the soaping process, which can reduce the production process, reduce water consumption, and improve color fastness, but its anti-staining The color effect is still not ideal

[0006] In the Chinese patent with the publication number CN102994259A, a low-temperature soaping agent is disclosed. Polyvinylpyrrolidone (PVP) is added to the formula. It has good solubility, dispersibility and good compatibility, and is compatible with many dyes. All have strong affinity and can achieve excellent anti-staining properties, but polyvinylpyrrolidone (PVP) is expensive, and it is not suitable to be an anti-staining agent in terms of cost
