Problems solved by technology

However, the enzyme cannot be refined alone. When the enzyme is degummed, complex surfactants must be added to assist the refining. Moreover, the enzyme smells bad, the production environment is poor, and the whiteness of the refined silk fabric is poor.

Abstract

The invention discloses an enzyme scouring agent for linen fibers. The enzyme scouring agent contains 2%-3% by volume of pectinase, 2%-4% by volume of glucanase, 2%-3% by volume of cellulose, as well as a 4-5g / L surfactant scouring agent and a 2-3g / L chelating agent, wherein a bath ratio is 1:30. The linen fibers are scoured by compound enzyme, so that the effect of removing impurities of pectin and lignin is very good; besides, the surfactant scouring agent and the chelating agent are added, thereby further reinforcing the impurity removing effect of the compound enzyme and effectively reducing the use amount of the compound enzyme; in addition, the scoured linen fibers achieve a degumming degree of 20%-23% and have a good handfeel, excellent whiteness and a fine capillary effect.

Description

technical field [0001] The invention relates to a method for refining silk fabrics, belonging to the technical field of textile engineering. Background technique [0002] Flax fiber is deeply loved by people for its excellent characteristics. There are a lot of impurities on a single flax fiber, such as pectin and lignin, which bring a lot of inconvenience to the dyeing and finishing of flax fiber. Among them, the content of cellulose in flax fiber It is about 60-70%, and the rest is impurities, and the content of pectin and cellulose in impurities accounts for 70-80%. How to remove impurities on flax fibers and minimize the damage of flax cellulose fibers , has always been the main problem of dyeing and finishing work. [0003] Choosing a suitable refining agent becomes the main way to solve the above problems. Enzyme is a kind of protein with special catalytic ability. The enzymatic training method utilizes protease to catalyze and decompose the protein of sericin, but c...
