Method for modifying and degumming jute fibers

Abstract

The invention discloses a method for modifying and degumming jute fibers, relating to the technical field of jute spinning. The degumming method comprises the following steps: (1) putting jute in a steamer, submerging all the jute into water, then adding sodium sulfite and a softening agent and steaming the jute at a high temperature being 105-115 DEG C for 6-9 hours; (2) fishing up the jute, washing the jute with clear water cleanly, then dehydrating the jute with a spin dryer and then drying the jute in the sun or drying the jute; (3) sending the jute onto a softening machine and adding linen softening oil and cellulase while beating the jute; (4) stowing the jute to be preserved at 20-30 DEG C for 3-7 days, thus degumming and modifying the jute into linen fabrics. Compared with the prior art, the method has the advantages and positive effects that the softness of the jute is improved and the spinnability of the jute is enhanced, thus solving the problem of scratchiness to the skins; the grade and the added values of the jute products are increased and great social and economic benefits are achieved; the state that the jute fiber resources are only used for extensive spinning for a long time and cannot be effectively utilized in the fields of garments and home textile fabrics is changed.

Description

technical field [0001] The invention relates to the technical field of hemp spinning, in particular to a method for denaturing and degumming jute fibers, in particular to a method for denaturing and degumming jute fibers with cellulase. Background technique [0002] Jute fiber is one of the cheapest natural fibers, second only to cotton in terms of cultivation and versatility. It belongs to the bast fiber (fiber extracted from the inner or outer bark of plants) like kenaf, hemp, flax, ramie, etc. The color of the fibers ranges from white to brown and is 1 to 4 meters long. [0003] Jute belongs to cellulose fiber, because of its unique fiber cavity structure, jute is rich in oxygen, and anaerobic bacteria cannot survive; it contains beneficial substances such as antibacterial ethanol, which also contributes to the health care of the human body; jute The excellent natural antibacterial properties of fibers are especially suitable for clothing and home textile fabrics, and c...

Problems solved by technology

[0004] Although jute fabric has excellent health care, comfort and environmental protection properties, but due to the high initial modulus of jute fiber, low elasticity and elongation at break, and poor recovery from tensile deformation, it is easy to form wrinkles and not easy to disappear. , affecting the appearance of the fabric

At the same time, jute fiber is hard and brittle, with high rigidity, which is easy to produce itching sensation, and it is difficult to meet the technical requirements of high-end clothing and home textile products.

[0005] At present, due to the above reasons, my country's jute processing industry is in a state of depression and bankruptcy; if jute is denatured and degummed into flax textile fibers, the jute textile industry will be brought back to life
