Abstract

The present invention provides a composite enzyme preparation for ramie boiling degumming and a preparation method thereof, wherein the composite enzyme preparation is a mixture of alpha-amylase, low-temperature amylase, alkaline pectinase, endo-beta-1,4-dextranase, neutral protease, oxidase, hemicellulase, beta-xylosidase, papain, keratinase, sorbitol, sodium hydroxide, tetraethyl orthosilicate, sodium metaaluminate and a nanometer desulfurization molecular sieve. According to the present invention, the one-step pickling in the traditional method is eliminated, the one-step alkaline boiling in the traditional process is replaced, a lot of the acid and alkali raw materials are saved, the advantages of mild treatment conditions, low cost, good fiber quality, low environmental pollution and the like are provided, and the efficiency is high compared to the traditional enzyme preparation.

Description

technical field [0001] The invention relates to a composite enzyme preparation and a preparation method thereof, in particular to a composite enzyme preparation used in ramie degumming and degumming and a preparation method thereof. Background technique [0002] Ramie (Bochmeria nivea) is a perennial herbaceous plant belonging to the Urticaceae family (Urticaceae). It is native to my country and is called "Chinese grass" by European and American countries. Its output accounts for about 80% of the world. By analyzing the components of ramie, its fiber content is more than 60%. Its bast fibers are particularly long and strong, and are the thinnest and longest among known hemp fibers. It is an important raw material for textile industry. Yet a large amount of colloids are attached on the ramie fiber, account for about 25-35% of total weight, mainly pectin, hemicellulose and lignin etc., according to the difference of ramie kind, its content can be as high as 24-45%. Therefore,...
