Problems solved by technology

Regarding the removal of floating color of reactive dyes, soaping agents are used. There are four main categories: surfactant compounded substances, which have good effect but high soaping temperature and are not easy to clean; alkaline substances compounded surfactants, It is easy to cause dye bond breakage and hydrolysis, which will affect the shade; compound laccases can destroy the chromophoric group of dyes, but they are selective to dyes and can easily cause color changes; Neutralize part of the alkali, but the acidity is insufficient, it needs to be compounded with strong acidic substances and the effect of removing floating color is not ideal
For example, the patent "A Low-Temperature Non-foaming Soaping Agent and Its Preparation Method" (publication number: CN102093508B) uses a compound of horse-beta copolymer and protective colloid, which has good dispersibility for dyes, but the copolymer used The molecular weight is relatively large, and the surfactant is not compounded. Under low temperature conditions, it is difficult to enter the interior of the fiber, and the penetration cleaning effect is poor, which reduces the floating color removal effect.
[0005] To sum up, the existing cleaning auxiliaries in the industry are all effective for a single type of dye, and there is a lack of one that is effective for both disperse dyes and reactive dyes. Soaping agent with good removal effect

Abstract

The invention provides a soaping agent for a polyester / cotton / spandex fabric and a preparation method pf the soaping agent. The soaping agent for the polyester / cotton / spandex fabric comprises the following components in percentage by weight of 20-40% of a water-soluble cucurbituril polymer; 15-35% of an acidic terpolymer; 5-15% of a green surfactant; and the balance of deionized water. The soaping agent for the polyester / cotton / spandex fabric has excellent removal and anti-staining effects on flooding of disperse dyes and reactive dyes, is relatively strong in acidity, can fully and effectively neutralize residual alkali after reactive dyeing, omits reduction cleaning and acid neutralization water washing, reduces the traditional nine cleaning procedures to four cleaning procedures, shortens the process, improves the efficiency, and reduces water consumption and wastewater discharge; the soaping temperature is reduced from 95 DEG C to 75 DEG C, so that the damage to spandex is avoided while the energy consumption is reduced; the treated fabric is small in colored light change, good in soaping effect, free of phosphorus, APEO and other substances, environment-friendly, safe and excellent in comprehensive performance, and the rubbing fastness and soaping fastness of the treated fabric reach or are superior to those of a traditional process.
