Abstract

The invention relates to a degumming method of linen yarn. The degumming method comprises following steps: (1) linen yarn is delivered into a yarn cage for 60 to 90min of immersing; (2) linen yarn is treated with an acetic acid solution with a concentration of 2.1ml / l for two times, and then is washed with cold water for one time; (3) linen yarn is subjected to degumming with pectinase; (4) linen yarn is heated to 100 to 120 DEG C rapidly, and then is subjected to acid washing with the acetic acid solution; (5) after acid washing, linen yarn is delivered into a soaping device for 30 to 50min of soaping with a soaping agent, and then water is discharged; (6) at normal temperature, linen yarn is subjected to degumming with xylitol enzyme; (7) linen yarn is washed with water for two times; (8) linen yarn is delivered into a centrifugal dehydrator for 3 to 5min of dehydration; and (9) the obtained linen yarn is dried for 60 to 90min. No damage on linen yarn is caused by the degumming method; no environment pollution is caused; and pectinase and xylitol enzyme with high selectivity are used for fabric degumming, so that spinning quality of linen yarn is improved, production cost is reduced, and pollutant discharge is reduced.

Description

technical field [0001] The invention relates to a degumming process of flax yarn. Background technique [0002] In the traditional process, the symbionts that must be removed from the flax fiber are treated with a large amount of alkali and sodium chlorite during the scouring and bleaching process, which not only produces a large amount of sewage, but also has certain damage to the fabric. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a degumming process of linen yarn with high efficiency, environmental protection and low cost. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: it is realized through the following steps: (1) put the flax yarn into the sarong and soak it for 60-90 minutes; [0005] (2) Treat the linen yarn with 2.1ml / l acetic acid solution for 2 times, and then wash it with cold water for 1 time; [0006] (3) Use pectinase to degumming li...
