Abstract

The invention discloses an imidazole modified laccase composite soaping agent and a preparation method thereof. The composite soaping agent comprises laccase, active agents, imidazole, assistants anddeionized water; the weight ratio of the laccase, the active agents, the imidazole, the assistants to the deionized water is (40-60):(1-3):(2-5):(1-5):(20-34); the active agents comprise, by weight, 12-24 parts of foam copper, 1-3 parts of nano-silica, 2-4 parts of rare-earth salt and 12-18 parts of hydrophilic high-molecular compounds. Compared with the prior art, the laccase is modified, and then modified by imidazole to serve as a main component of the soaping agent, the activity and stability of enzyme in a nano-composite catalyst are improved, the usage amount of the laccase is reduced, and the cost of the soaping agent is reduced. A fabric cleaned by the imidazole modified laccase composite soaping agent is good in surface dyeing removing effect, and anti-dipping rate is reduced.

Description

technical field [0001] The invention belongs to the field of finishing aids for textiles, and in particular relates to an imidazole-modified modified laccase composite soaping agent and a preparation method thereof. Background technique [0002] At present, the raw materials of soaping agents are mostly inorganic salts, polyacrylic acid, organic phosphates, polymers, and surfactants. This type of soaping agent needs to be soaped many times to improve the bright color of the fabric. degree, color fastness, this type of soaping process is inefficient and consumes water and energy. On the market, the kind of soaping agent is a lot, but all has certain deficiency, [0003] Surfactants can not only reduce the interfacial tension of the organic / aqueous two-phase system, but also affect the conformation of enzyme molecules, which can improve the stability of enzyme molecules to a certain extent. However, free enzymes are usually used only once in solvents containing surfactants, ...
