Jute fiber degumming process

Abstract

The invention discloses a jute fiber degumming process. The jute fiber degumming process mainly comprises the following steps of raw jute cleaning, raw jute pickling, rinsing, primary alkali-hydrogen peroxide bathing, raw jute beating, rinsing, acid pickling, washing and airing. Jutes are degummed and bleached by using the primary alkali-hydrogen peroxide bathing method, the alkali and hydrogen peroxide are mutually acted, the alkali removes gum, hemicelluloses, xylogen and other impurities in jute fibers and also provides an alkali environment for the decomposition of hydrogen peroxide; hydrogen peroxide is very stable in an acid medium, and the decomposition velocity is very low; however, hydrogen peroxide can be activated in an alkali medium, and hydrogen peroxide molecules are decomposed to bleach the jute fibers. Simultaneously, and particularly importantly, the xylogen can be oxidized, and the oxidized xylogen can be dissolved in high-temperature strong aqueous alkali under experiment conditions, so that the removal of the xylogen is facilitated.

Description

[0001] technical field [0002] The invention belongs to the technical field of textiles, and in particular relates to a jute fiber degumming process. [0003] Background technique [0004] The main components of jute fiber are cellulose, hemicellulose and lignin. Jute fiber has high strength and hygroscopicity, is a good insulator of heat and electricity, is the most biodegradable among natural fibers, and does not produce toxic gases when it degrades or burns. With the development of jute machinery and chemical processing technology, high-quality jute and its blended fabrics with other fibers have been spun, and the rough and hard feel of jute has also been improved. Many other fields have great potential for development. The quality of hemp textile products mainly depends on the degumming of hemp. For a long time, the degumming of raw hemp has been carried out by natural fermentation and chemical methods. The natural degumming method is greatly affected by the enviro...
