Problems solved by technology

[0005] The technical problem to be solved by the present invention: Aiming at the problems of low strength, brittleness and poor cohesion of the horn melon fiber which are not conducive to spinning, the invention provides a preparation method of the horn melon fiber blended yarn fabric. The invention uses chitosan as a raw material, reacts with succinic anhydride, and grafts and modifies the surface of chitosan to obtain surface N-succinylated chitosan, which is then dissolved with polyvinyl alcohol to form a treatment solution. Soak melon fiber in the treatment solution, adhere to the surface of the melon fiber, improve the antibacterial and mechanical properties of the melon fiber, and then blend it with cotton fiber and polyester staple fiber to further improve its mechanical properties, and finally spin the yarn according to The weft plain stitch structure is interwoven and formed, and the blended yarn fabric of the horn gourd fiber is obtained

Abstract

The invention relates to a method for preparing akund fiber blended yarn fiber, and belongs to the technical field of textile fabrics. The method includes: using chitosan as a raw material, allowing the chitosan to react with succinic anhydride, and performing surface grafting modification on the chitosan to acquired N-succinyl modified chitosan; dissolving the N-succinyl modified chitosan in polyvinyl alcohol to acquire a processing solution; soaking akund fibers in the processing solution; allowing films to be attached to surfaces of the akund fibers so as to improve the antibacterial performance and the mechanical property of the akund fibers; blending the akund fibers with films on the surfaces thereof, cotton fibers and polyester staple fibers into yarns to improve the mechanical property; and interweaving the yarns according to a weft plain stitch structure into the akund fiber blended yarn fabric. The prepared akund fiber blended yarn fabric is excellent in fabric tensile mechanical property, abrasive resistance, air permeability and thermal insulation property, is good in antibacterial effect, and can greatly expand the application range of the akund fiber blended yarn fabric in spinning.

Description

technical field [0001] The invention relates to a method for preparing a gourd fiber blended yarn fabric, belonging to the technical field of textile fabrics. Background technique [0002] In recent years, with the possible depletion of petroleum resources, there will be a problem in the supply of raw materials for chemical fibers that rely on petroleum as raw materials. At the same time, the price of cotton fiber has fluctuated greatly in recent years, and it is difficult to maintain a stable balance between supply and demand. In particular, the rapid growth of the global population has made it impossible to expand the cotton planting area. In addition, people's awareness of environmental protection has gradually strengthened, and traditional chemical fibers are facing acute problems that are difficult to degrade naturally, so people began to turn their attention to various green and environmentally friendly new fibers. [0003] Crow's horn melon fiber, also known as cryst...
