Abstract

The invention provides a low-temperature soaping enzyme. The low-temperature soaping enzyme is prepared from the following raw materials in percentage by weight: 10 to 50 percent of alkaline lipase, 10 to 25 percent of a vinyl pyrrolidone co-polymer, 10 to 40 percent of a maleic acid type co-polymer, 10 to 30 percent of a phenol sulfonic group condensation compound and 5 to 15 percent of an auxiliary agent. According to the low-temperature soaping enzyme provided by the invention, all the components are cooperatively matched to realize textile stain removing, flooding removing and color fixingcomprehensive acting effects through a stain removing effect of the alkaline lipase, an anti-staining effect of the vinyl pyrrolidone co-polymer, a flooding removing effect of the maleic acid type co-polymer and a color fixing effect of the phenol sulfonic group condensation compound. Furthermore, the low-temperature soaping enzyme provided by the invention can be used for carrying out soaping under a low-temperature condition and the environmental protection effects with low energy consumption, low emission and low pollution are realized. The invention further provides a preparation method and application of the low-temperature soaping enzyme and a low-temperature soaping technology.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing soaping, and in particular relates to a low-temperature soaping enzyme, a preparation method of the low-temperature soaping enzyme and a low-temperature soaping process. Background technique [0002] Reactive dyes have complete color spectrum, bright color, low cost and mature dyeing process. Therefore, more than 80% of cellulose fibers are dyed and printed with reactive dyes. There are many kinds of reactive dyes with various chemical structures and different reaction efficiencies, but none of them can completely react with cellulose fibers. In addition, while the fixed fiber is dyed, the dye will also be hydrolyzed, that is, the active group in the reactive dye is replaced by a hydroxyl group to form a hydrolyzed dye. These unfixed dyes and hydrolyzed dyes have very similar diffusion and adsorption properties to the original reactive dyes, so they are easily adsorbed on the fiber s...
