Abstract

The invention relates to a combined degumming technological method for jute or kenaf. The method comprises the following steps: conducting organic solvent pretreatment on the jute or kenaf, conducting steam explosion and ammonia immersion treatment, then conducting ultrasonic bleaching to remove most gum in the original jute or kenaf, and relying on the residual gum to bond jute or kenaf single fiber and form a technological fiber capable of being utilized by textile processing. Test results show that by combination of the organic solvent, and the steam explosion and ammonia immersion methods, gum of hemicellulose, lignin and the like in the jute or kenaf can be effectively removed, the jute or kenaf fiber prepared by the method is high in splitting degree and good in flexibility, and the degumming method is low in cost, energy-saving, environment-friendly, simple to operate, and suitable for bast-fiber degumming treatment in spinning.

Description

technical field [0001] The invention relates to a process method for joint degumming of jute or kenaf, which belongs to the field of textile processing. [0002] technical background [0003] With the rapid development of my country's society and economy, people's demand for textiles continues to increase. People are gradually aware of the shortage of textile fiber raw materials, and are actively looking for another way out for textile fiber resources. Cellulose is the most abundant renewable resource on earth, and the development of new natural plant fiber textile raw materials will help break through the bottleneck of textile fiber resources. In recent years, the development and utilization of biomass materials has become a research hotspot. [0004] In addition, people's requirements for the comfort of textiles are getting higher and higher. Hemp products are gradually gaining people's favor because of their excellent hygroscopicity, air permeability and unique style. ...
