Making method for cuprammouium rayon/viscose fiber antibacterial blended fabric

Abstract

The invention discloses a making method for cuprammouium rayon / viscose fiber antibacterial blended fabric. Selected warp and weft materials comprise, by mass, 35-40 parts of cuprammouium rayon, 40-90 parts of viscose fibers, 20-25 parts of silk, 8-15 parts of bamboo charcoal fibers, 30-35 parts of cotton fibers, and 8-18 parts of super fine denier polyester; scutching procedures comprise primary washing and fine washing steps, in the primary washing step, the cuprammouium rayon, the viscose fibers, the silk, the bamboo charcoal fibers, the cotton fibers and the super find denier polyester are put into a washing machine in a classified mode, the bath ratio is 1:30-50, mild detergent is added, the dosage of cleaning agent is 4-5 g / L, the water temperature ranges from 55 DEG C to 65 DEG C, and the washing time ranges from 0.5 h to 0.8 h; in the fine washing step, the cuprammouium rayon, the viscose fibers, the silk, the bamboo charcoal fibers, the cotton fibers and the super find denier polyester are immersed in clear water, the bath ratio is 1:11-15, a mild detergent solution with the mass concentration ranging from 26% to 32% is added, the addition quantity in the water is 6-9 g / L, processing is conducted for 0.5-0.8 h, and the temperature for the fine washing ranges from 66 DEG C to 72 DEG C.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a preparation method of cupro ammonia fiber / viscose fiber antibacterial blended fabric. Background technique [0002] Viscose fiber, one of the main varieties of man-made fibers; alkali cellulose is formed from natural cellulose, and then reacted with carbon disulfide to form cellulose xanthate, and the viscous solution obtained by dissolving in dilute lye is called viscose , viscose becomes viscose fiber after wet spinning and a series of treatment processes; but due to the inherent properties of viscose fiber itself: the fiber is relatively fluffy, the single fiber is also relatively brittle, and the weavability is poor. There are many problems that are difficult to overcome, such as: the fibers are fluffy, the cohesion between the fibers is poor, the static electricity is more serious during the spinning process, the hairiness is more, the fibers are easy to stick, the cotton...

Problems solved by technology

[0002] Viscose fiber, one of the main varieties of man-made fibers; alkali cellulose is formed from natural cellulose, and then reacted with carbon disulfide to form cellulose xanthate, and the viscous solution obtained by dissolving in dilute lye is called viscose , viscose becomes viscose fiber after wet spinning and a series of treatment processes; but due to the inherent properties of viscose fiber itself: the fiber is relatively fluffy, the single fiber is also relatively brittle, and the weavability is poor. There are many problems that are difficult to overcome, such as: fluffy fibers, poor cohesion between fibers, more serious static electricity, more hairiness, easy adhesion of fibers, cotton nets easy to fall, easy to block the bell mouth, etc.

[0003] Cupro fiber is a kind of regenerated cellulose fiber. It is made by dissolving natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution. The cellulose molecular compound is decomposed to regenerate cellulose, and the resulting hydrated cellulose is post-processed to obtain cupro fiber; the cross-section of the cupro fiber is circular, without a skin-core structure, and the fiber can withstand high elongation, and the obtained monofilament It is thinner, so the fabric feels soft, has a soft luster, and has a silk feel; because cupro fibers have poor resistance to oxidants such as chlorine bleach and hydrogen peroxide, the fabrics blended with cupro fibers and other fibers should be used in the follow-up. There are certain difficulties in the process of processing, dyeing and finishing

[0004] When traditional cotton and polyester raw materials are used in spring and summer clothing fabrics, they have the disadvantage of poor perspiration effect and poor antibacterial effect
