Abstract

The invention discloses a low temperature soaping enzyme. The low temperature soaping enzyme is prepared by mixing the following raw materials by mass: 10 to 20% of laccase, 10 to 30% of manganese catalase, 10 to 20% of glucose oxidase, 20 to 30% of polyvinylpyrrolidone K-30, 10 to 20% of maltodextrin and 5 to 15% of fatty alcohol polyoxyethylene ether. The invention also discloses application of the low temperature soaping enzyme in reactive dyeing and soaping process. Though soaping with the above-mentioned soaping enzyme at 60 to 70 DEG C, a soaping effect is effectively improved, process flow of soaping is shortened, production efficiency is improved, cost and energy are saved, emission is reduced, and the indexes of TDS, BOD and COD in wastewater are decreased.

Description

technical field [0001] The invention relates to a low-temperature soaping enzyme and its application in active dyeing soaping process, which belongs to the technical field of fabric dyeing and finishing soaping process. Background technique [0002] With the different dyeing and printing soaping equipment and the update of the process, the fabric dyes are different. Therefore, the types and varieties of soaping agents to meet the requirements of the soaping process are also different. Existing soaping agents can be divided into three categories: general soaping agents, acidic soaping agents, and anti-staining soaping agents, all of which have different process conditions and requirements. Most of the soaping agents sold in the market are alkaline phosphorus-containing soaping agents, soaping agents compounded by various surfactants, or horse-propylene copolymer soaping agents. They are all liquid products in aqueous solution, packaged The transportation is inconvenient and ...
