Jute degumming method

Abstract

Provided is a jute degumming method. The method comprises the steps that soaking is conducted on jute raw hemp for 24 hours by means of warm water, and the jute raw hemp is taken out for airing; continuous washing is conducted by means of the warm water till the structure is loosened, wherein 2%-3% of soluble emulsified oil is added into the warm water, the warm water is 1 m away from the raw hemp, and the hydraulic pressure ranges from 40 Mpa to 60 Mpa; the raw hemp is put into cold water to sway for 30 min, standing is conducted for 2 hours, and the raw hemp is taken out and spin-dried. According to the jute degumming method, the soluble emulsified oil is added into the warm water through the medium pressure to conduct lasting impact, the impact strength and temperature are moderate, prepared jute fibers are complete in fibers, the jute fibers can not be destroyed, and pectin is completely removed; due to the fact that the integrality of the fibers is kept, the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of hemp fiber production, in particular to a jute degumming method. Background technique [0002] Hemp is a fiber obtained from various hemp plants, including bast fibers from the cortex of annual or perennial herbaceous dicotyledonous plants and leaf fibers from monocotyledonous plants. Hemp mainly includes ramie, jute, green hemp, hemp, hemp, flax, apocynum and kenaf. It is especially suitable for people with beriberi, foot odor, and body odor to use hemp fiber fabrics. Hemp fiber has advantages that other fibers cannot match: it has good moisture absorption and ventilation functions, fast heat transfer and heat conduction, cool and crisp, sweating is not close to the skin, texture Lightweight, strong, insect-proof and mildew-proof, less static electricity, fabrics are not easy to pollute, soft and generous, rough, suitable for excretion and secretion of human skin, etc. Studies have shown that among num...

Problems solved by technology

[0003] The current methods of degumming to obtain hemp fibers include chemical treatment methods. The degree of fiber separation in chemical treatment is the largest, but the damage to hemp fibers is also greater, and this method is easy to excessively damage the hemp fibers during the degumming process. The whole hemp fiber is destroyed to form short fibers, and a large amount of pollutants will be produced, which not only affects the performance of the hemp fiber, but also greatly increases the processing cost
