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 refining method of real silk fabrics, belonging to the technical field of textile engineering. Background technique [0002] Flax fiber is deeply loved by people for its excellent characteristics. A large number of impurities, such as pectin and lignin, exist on single flax fiber, and the dyeing and finishing process of flax fiber brings a lot of inconvenience. Among them, the content of cellulose in flax fiber About 60-70%, and the rest are impurities, and the content of pectin and cellulose in the impurities accounts for 70-80%. How to remove impurities on flax fiber and minimize the damage of flax cellulose fiber , has been the main problem of dyeing and finishing work. [0003] Selecting a suitable refining agent has become the main way to solve the above problems. Enzyme is a protein with special catalytic ability. The enzymatic training method uses protease to catalyze the decomposition of sericin protein, but cannot ...
