Problems solved by technology

This invention can effectively remove the floating color on the fabric, but a large amount of pollutants will be discharged during use, which increases the environmental burden and is not conducive to continuous use
In addition, the invention patent 201210135651.2 also discloses a preparation method of a low-temperature soaping agent. Although the formula has a good soaping effect, the preparation method contains a large amount of triethylamine, which forms a large amount of ammonia nitrogen in the aqueous solution. There is a large pollution to the environment, which increases the burden of subsequent environmental pollution treatment and increases the cost of treatment
At the same time, the production-use compounding method of this configuration mixes several raw materials together, which fails to reflect the effect of excellent low-temperature soaping, and still needs to be soaped at an ambient temperature of about 60°C, and the energy consumption remains the same. Very high, not conducive to the rational allocation of resources

Abstract

The invention discloses a preparation method and application of an environment-friendly low-temperature soaping agent applied in the field of chemical textile auxiliaries. The preparation method comprises the following steps of preparing raw materials; carrying out reaction by stirring maleic anhydride, polyethylene glycol and catalyst; cooling and filtering; mixing the filtrate, deionized water,isopropanol, N-vinylpyrrolidone and adding initiator; cooling and adding sodium bisulfite to obtain surfactant A; mixing the surfactant A, sodium carboxymethyl cellulose, citric acid, glycerol and deionized water. According to the invention, no ammonia nitrogen or phosphorus is generated after use, so that the pollution of the environment in production and use process is avoided, and the environmental protection performance of the product is effectively improved. In addition, the soaping agent produced in the preparation process utilizes the ternary copolymerization, greatly improves the soaping performance of the product and reduces environment temperature for soaping to the range of 40-50 DEG C, effectively reduces the production cost and provides the guarantee for the reasonable allocation of resources in the production process.

Description

technical field [0001] The invention relates to a preparation method and application of an environment-friendly low-temperature soaping agent used in the field of chemical textile auxiliaries. Background technique [0002] With the improvement of living standards, people are not only limited to the hydrophilic and soft properties of cotton fabrics, but also gradually increase their color requirements for fabrics. In order to meet the color needs of people in daily activities, the fabric will be dyed with reactive dyes during the production process, thereby improving the color richness of the fabric, expanding the application range of the product, and ensuring customer satisfaction with product color. However, in order to ensure the dyeing quality during the dyeing process, the amount of dye used is usually much greater than the amount absorbed by the fabric, resulting in a large amount of undyed dye remaining on the fabric after dyeing. Although dyes use safe reagents as fa...
