Abstract

The invention relates to a peeling and degumming process for hemp plants, comprising: peeling off the hurds from the stalk, peeling the hurds by acid enzyme and removing the woodiness by alkali enzyme and lignin. The method abolishes the procedure of mechanically peeling off hurds so as to avoid the fiber loss during peeling off hurds and improve the 15% of yield. Meanwhile, the degumming process needs less water, degumming time, low acid and alkali concentration in the boiling liquid. The boiling liquid can be recycled.

Description

(1) Technical field

[0001] The invention relates to a method for peeling and degumming hemp plants, which belongs to the field of fiber preparation. (2) Background technology

[0002] The method for removing the skin of hemp plants at present is to scrape off the skin of the hemp skin by mechanical means with the hemp skin peeled off from the hemp stalk, which will lose about 15% of the hemp fiber and consume more manpower simultaneously; It uses chemical method to cook at high temperature in acid-base solution, which consumes a lot of water and is harmful to hemp fiber. Recently, biological methods are used for degumming, but the time required for degumming is very long, the cost is high, and it is difficult to adapt to industrial production. It is still immature and seriously restricts the development of hemp spinning industry. (3) Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a biochemical peeling and degum...
