Abstract

The invention relates to an alkaline pectinase preparation for cannabissalival degumming, wherein the components of the alkaline pectinase preparation comprise: an alkaline pectinase or an alkaline pectinase compound enzyme preparation, wherein the alkaline pectinase compound enzyme preparation is a mixture comprising an alkaline pectinase and one or a plurality of materials selected from pectinase, xylanase, mannanase, lipase and protease. According to the present invention, the alkaline pectinase preparation has characteristics of effective cannabissalival degumming and short degumming time, and the obtained fibers have characteristics of low gum residue, softness and less damage.

Description

technical field [0001] The invention belongs to the technical field of textile industry and relates to hemp degumming, in particular to an alkaline pectinase preparation for hemp degumming and a hemp degumming method. Background technique [0002] Hemp (annual herb of the genus Moraceae), scientific name cannabissalival, common name hemp, cold hemp, thread hemp, flower hemp, etc., English name hemp, truehemp, commonhemp, has about 150 varieties, is an ancient tough Leather fiber crops are also the earliest fiber crops planted by the Chinese nation and used for clothing and food. Hemp fiber has the characteristics of moisture absorption, breathability, heat resistance and antibacterial, anti-ultraviolet radiation, anti-radiation, anti-static, etc. It is an environmentally friendly fiber raw material. It has great application potential in many aspects and is the most promising natural fiber in the future. vegan fiber. [0003] In order to utilize the hemp fiber, hemp degummi...
