Problems solved by technology

But according to the existing usage of jute and kenaf fiber, the fineness of jute and kenaf fiber is ordinary jute fiber, and the fineness is about 300-400 public branches, and the fiber hardness is large and the cohesion is poor. At present, it can only be used with cotton, Wool, chemical fiber and other fibers are blended to produce coarse-count yarns with a low proportion and a fineness of less than 21 pounds, which cannot meet the requirements of pure spinning
And the spun jute and kenaf blended yarn can only be used for decorative fabrics such as towels, carpets, sofa releases, curtains, etc.

Abstract

The invention discloses refined jute-kenaf fiber and a preparation method thereof. The fiber fineness of the jute-kenaf fiber is greater than 600 Nm, the fiber whiteness is greater than 50, and the strength is greater than 2.5 cN / dtex. In the degumming process of the preparation method disclosed by the invention, a method of combining bio-enzyme degumming with traditional chemical refining is adopted so as to further remove colloid from the jute-kenaf fiber and refine the jute-kenaf fiber without damaging the strength of the jute-kenaf fiber. The refined jute-kenaf fiber disclosed by the invention has the advantages of high fineness, high strength and good spinnability, and can be independently spun or blended with cotton, silk and other fibers to prepare top-grade products, thereby overcoming the defect that the jute-kenaf fiber cannot be applied to the field of top-grade products; and meanwhile, the antibacterial, humidity-absorbing and breathable functions of the product are increased, the varieties of the product are enriched, raw materials such as cotton, silk, chemical fiber and the like can be partially replaced, and the pressure on resource shortage is reduced.

Description

technical field [0001] The invention belongs to the field of textile engineering, in particular to a refined jute kenaf fiber and a preparation method thereof. Background technique [0002] With the development of human society, natural resources are constantly being developed and utilized. The shortage of natural resources, especially the scarcity of non-renewable resources such as coal and oil, makes the price of chemical fibers that replace some natural fibers continue to rise, and as the second largest natural fiber Jute and kenaf fibers are more and more valued by people because of their convenient materials and low price. Because of its thick, hard, and high colloid content, yellow-red fiber has been used as a low-grade textile raw material in the past, and is generally only used to make hemp rope and sacks. Now, some people have used jute and kenaf fiber in textiles, textiles, etc. Clothing fabric. But according to the existing usage of jute and kenaf fiber, the fin...
