A kind of preparation method of cupro ammonia fiber/viscose fiber antibacterial blended fabric

Abstract

The invention discloses a method for manufacturing a cupro ammonia fiber / viscose fiber antibacterial blended fabric. The selected warp and weft thread materials are calculated in parts by mass: 35-40 parts of cupro fiber, 40-90 parts of viscose fiber, and 20 parts of silk ‑25 parts, 8‑15 parts of bamboo fiber, 30‑35 parts of cotton fiber, 8‑18 parts of superfine polyester. Glue fiber, silk, bamboo fiber, cotton fiber and ultra-fine polyester are sorted into the washing machine with a bath ratio of 1:30‑50, and a neutral detergent is added. The amount of cleaning agent is 4‑5g / L. The temperature is 55-65°C, and the washing time is 0.5-0.8 hours; in the fine washing step, soak cupro, viscose fiber, silk, bamboo fiber, cotton fiber and superfine polyester in clean water, with a bath ratio of 1: 11-15, and add a neutral fine detergent solution with a mass concentration of 26-32%, the amount added is 6-9g / L per liter of water, the treatment is 0.5-0.8 hours, and the fine washing temperature is 66-72°C.

Description

Technical field [0001] The invention belongs to the technical field of textiles, and particularly relates to a method for manufacturing a 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 made from natural cellulose through alkalization, and then reacts with carbon disulfide to generate cellulose xanthate, and the viscous solution obtained by dissolving in dilute lye is called viscose , Viscose is made into viscose fiber after wet spinning and a series of processing procedures; but due to the inherent properties of viscose fiber itself: the fiber is relatively fluffy, the single fiber is also relatively brittle, and the weaving ability is poor. There are many difficult to overcome problems such as: the fiber is relatively fluffy, the cohesive force between the fibers is poor, and the spinning process is prone to more static electricity, more hairiness, fibe...

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
