Problems solved by technology

However, traditional anti-stain soaping agents need to be used at high temperatures (98°C), and a large amount of washing water is required, which consumes a lot of energy
What is more critical is that there is still a lack of research reports on the application performance of soaping agents that not only have soaping effects but also decolorize the soaped dyes, thereby reducing the burden of printing and dyeing wastewater treatment.

Abstract

An environmentally friendly soaping agent is disclosed. Preparation of the soaping agent includes: 1) preparing macroporous silicon dioxide, 2) preparing a chitosan solution, 3) immobilizing laccase and 4) preparing the soaping agent. The soaping agent is advantageous in that: (a) the soaping agent is free of acid washing, thus reducing environment pollution; (b) the soaping agent has excellent properties, namely, the soaping agent has good chelating, dispersing, suspending, and washing properties, and the soaping agent is capable of effectively removing flooding, protecting fabric from being contaminated by the flooding, guaranteeing the colour fastness, and making the color tune more bright and pure and the fabric surface cleaner; (c) the soaping agent can achieve low-temperature soaping, and is suitable for soaping at a temperature lower than 60 DEG C, excellent in anti-staining property and capable of reducing thermal loss; (d) foams are few; and (e) work hours are reduced and are only 30% of work hours of an original process, washing steps are largely reduced, the water using amount is only a quarter of an original water using amount, the process time is shortened, the cost and the treating load of waste water are reduced, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to an environment-friendly soaping agent. Background technique [0002] The soaping process after textile dyeing and printing can remove the floating color on the surface of the fabric and improve the fastness of the dyed fabric. Adding soaping agent can improve the effect of washing and removing floating color, and make the dye no longer stick to the fabric through dispersion, suspension and complexation, so as to achieve the purpose of improving soaping fastness and anti-staining. [0003] With the increasing demand for high-grade composite fiber fabrics, the demand for soaping agents is also increasing. The raw materials of traditional anti-staining soaping agents are mostly inorganic salts, polyacrylic acid, organic phosphoric acid, high molecular polymers, and surfactants, which have good soaping and anti-staining effects on fabrics dyed with reactive dyes , For example, the Chinese patent 201210412429 with strong antifouli...
