Problems solved by technology

[0002] In the prior art, chemical materials are used to degumming flax, but the quality of degumming cannot be guaranteed and the spinnability of fibers is poor. This not only consumes a large amount of chemical raw materials and energy such as alkali and acid, but also increases the cost and produces waste water. Caused serious environmental pollution; degumming with biological enzymes can greatly reduce the pollution caused by degumming wastewater, and can also improve the spinnability of hemp fiber, but there are problems of long degumming time and high cost

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0021] The invention relates to a process of combining flax biological enzyme, chemical degumming and bleaching. In order to solve the problems existing in the current known technology and overcome its defects, and realize the purpose of the invention to improve the quality of flax products, the present invention adopts a new process combining flax biological enzymes and chemical degumming and bleaching. The technical scheme that the present invention takes is:

[0022] The chemical composition of flax fiber is roughly:

[0023] Cellulose 61%, hemicellulose 17%, lignin 9%, pectin 3.6%, water soluble 5.7%, wax 1.7%, ash: 2%.

[0024] Process flow of flax bioenzyme and chemical degumming combined...

Abstract

The invention discloses a process for combining flax enzyme and chemical degumming with bleaching. The process comprises the steps of flax filling and preliminary acid water washing; enzyme degumming; bleaching pre-treatment; water washing; oxidation bleaching; water washing; neutralization and water washing; dehydration; softening treatment; dehydration; and loosing for drying. The process improves the hydrophilicity and lubricity of fibers, enhances the whiteness and softness of fibers and greatly reduces the content of lignin in fibers, thereby enhancing the spinnability of fibers. The fibers treated by the process have the advantages of strong tension, softness, good fineness, weak electrical conductivity, rapid water absorption and diffusion, high expansivity and the like, and have the functions of temperature control, antianaphylaxis, antistativity and antibacterium, and the fibers can be spun into high and low yarns or blended with other fibers to make high-class cloth. The profit rate is about 50%, thereby creating good economic benefit..

Description

technical field [0001] The invention belongs to the technical field of textile industry production technology and relates to flax weaving technology. More specifically, the present invention relates to a process of combining biological enzymatic and chemical degumming and bleaching of flax. Background technique [0002] In the prior art, chemical materials are used to degumming flax, but the quality of degumming cannot be guaranteed and the spinnability of fibers is poor. This not only consumes a large amount of chemical raw materials and energy such as alkali and acid, but also increases the cost and produces waste water. Serious environmental pollution is caused; degumming with biological enzymes can greatly reduce the pollution caused by degumming wastewater, and can also improve the spinnability of hemp fiber, but there are problems of long degumming time and high cost. Contents of the invention [0003] The problem to be solved by the present invention is to provide ...
