Processing method for refining jute fiber

Abstract

The invention discloses a processing method for refining a jute fiber, which comprises adopting sodium hydroxide solution to perform chemical degumming on raw jute after water bath or acid bath is carried out to the raw jute, adopting pectinase or laccase to perform biological enzyme degumming, and performing chemical degumming after physical refining is carried out to the jute fiber where a softening agent is sprayed. Damage to the fiber is reduced by adding the softening agent, the fineness is remarkably improved, the softening agent which is sprayed to the jute fiber prior to the physical refining of the jute fiber can reduce friction between the jute fibers, unnecessary fiber breakage is reduced when the physical refining is performed, the fact that the fiber is not damaged is guaranteed, the fiber strength is prevented from being lowered, part of colloid and impurity are exposed out of a surface layer of the fiber due to split separation of the jute fiber after physical refining, the colloid and impurity on the surface layer of the fiber can be removed through chemical degumming treatment after physical refining, the fiber can be further refined, the costs are reduced, and utilizing rate is improved.

Description

technical field [0001] The invention relates to the field of textile engineering, in particular to a method for processing refined jute fibers. 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 popular in the development and utilization of jute fibers due to their convenient materials and low prices. However, jute fibers are thick, hard, and have high gum content. In order to remove the glue in jute fibers quality, thinning jute fiber, existing people have applied biological enzyme degumming, chemical method degumming or biological enzyme combined chemical method degumming treatment method to jute fiber degumming, but the ref...

[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 popular in the development and utilization of jute fibers due to their convenient materials and low prices. However, jute fibers are thick, hard, and have high gum content. In order to remove the glue in jute fibers quality, thinning jute fiber, existing people have applied biological enzyme degumming, chemical method degumming or biological enzyme combined chemical method degumming treatment method to jute fiber degumming, but the refining effect of jute fiber is not ideal, through prior art The fineness of jute fiber after the disclosed bio-enzyme combined with chemical method degumming is about 400-500 public branch, and the fiber hardness is big, cohesive force is poor, can only be mixed with cotton, wool, chemical fiber and other fibers to produce low-ratio, The fineness is a thick yarn below 21 pounds, and the spun jute blended yarn can only be used for decorative fabrics such as towels, carpets, sofa releases, curtains, etc. The refinement and spinnability of jute fibers are not only Today, and for years to come, it will be an intractable problem
