Problems solved by technology

[0002] According to test analysis, the total amount of cellulose in the whole bark of mulberry without scraping green is not high (23%~30%), because the epidermis and green cortex contain more hemicellulose, lignin, pectin and water-soluble substances respectively, so Directly adopting the traditional chemical degumming method to refine mulberry fiber processing consumes a lot of medicines, heavy pollution, poor fiber quality and high cost

Embodiment 1

[0017] Firstly, the mulberry branches are peeled. The mulberry peeling process includes three parts: felling, hammering, and peeling. The required equipment includes sickle and hammer. The stripping time is carried out when fresh mulberry branches, the second step is soaking, peeling, and then degumming. The degumming step is: the degumming bacteria made by the selected degumming bacteria (selected and preserved by the School of Life Science and Technology, Guangxi University) The liquid was inoculated on the mulberry bark (Gui Sangyou No. 12 and No. 62), and the instruments used mainly included SPX-250 biochemical incubator, HQL300A cabinet type refrigerated constant temperature shaker, SW-CJ-1F purification workbench, UV-1601 type UV spectrophotometer, etc. Wherein, the inoculum amount of the degumming solution is 10%.

[0018] The effect of different inoculum amounts on degumming was studied, and the results showed that the degumming effect was best when 10% inoculum amoun...

Abstract

The invention discloses a method for extracting mulberry bark fibers. The synthetic technology uses a biological method as the primary method and a chemical method as the auxiliary method. Through surface skin removing, refining, bleaching, cleaning, softening, drying, carding and other processing technologies, the mulberry bark fibers are extracted and can be applied to the development of mulberry-bark series textile products and mulberry-bark pure or blended products which are high in additional value and good in market prospect, a large quantity of waste mulberry bark and stem resources turn into raw materials which can be used for industrial production and into consumer goods high in additional value. The method has the advantages of being clean in production, high in technological content and good in economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of fiber production, in particular to a method for extracting mulberry bark fiber. Background technique [0002] According to test analysis, the total amount of cellulose in the whole bark of mulberry without scraping green is not high (23%~30%), because the epidermis and green cortex contain more hemicellulose, lignin, pectin and water-soluble substances respectively, so Directly adopting the traditional chemical degumming method to refine mulberry fiber for processing consumes a lot of medicines, causes heavy pollution, poor fiber quality and high cost. Microbial degumming is to inoculate the selected degumming strains on the mulberry bark, and use the mulberry pectin as a nutrient source. The macromolecules are decomposed into low-molecular substances and dissolved in water, and a series of biochemical reactions of "glue culture, bacteria production, and enzyme degumming" occur under mild conditions. Th...
