Process for manufacturing antimicrobial conductive acrylic fibre fibre

Abstract

The invention belongs to a manufacture method of an antibacterial conductive acrylic fiber, which is characterized by being composed of the following steps: (1) arranging the acrylic fiber into a reaction vessel, then pouring a solvent into the reaction vessel, dissolving copper salt containing Cu<2+> into the solvent, adjusting the pH valve of the solution to be between 1.5 to 3.0, then adding a reducer and heating, maintaining the temperature of the solution to be between 90 to 100 DEG C, carrying out reduction on the Cu<2+> by utilizing the reducer to generate Cu<+> and lead the Cu<+> to be absorbed on the acrylic fiber; (2) adjusting the pH value of the solution to be between 1.5 to 3.0 and then maintaining the temperature of the solution to be between 40 to 120 DEG C, adding salt containing sulfur atoms and leading a great amount of Cu<+> to be oxidized to generate the Cu<2+> after the reaction time lasts 2 to 4 hours; thereby generating a sulfide of copper that is not easy to be dissolved in the solvent to lead the sulfide of copper to be sufficiently and uniformly dispersed on the surface of the whole fiber. The copper sulphide in the acrylic fiber manufactured by utilizing the method is dispersed on the surface of the whole fiber. The self physical and chemical characteristics of the copper sulphide lead the fiber to have excellent antibacterial property and conductibility; the copper sulphide on the fiber surface is not easy to fall off and has excellent anti-washing property.

Description

Technical field: [0001] The invention designs a method for manufacturing chemical fibers, in particular relates to a method for manufacturing antibacterial conductive acrylic fibers. Background technique: [0002] Acrylic fiber is the trade name of polyacrylonitrile fiber in our country. Acrylic fiber has high elasticity, strength, heat resistance, light resistance and corrosion resistance, and is widely used in the textile industry. Because its properties are close to wool, it is called "synthetic wool". With the improvement of people's living standards, personal hygiene and health have received widespread attention, and some fiber textile products that are closely related to people's lives have also received people's attention; For example, static electricity can cause flammable gas to burn or even explode, cause damage and failure of semiconductors and precision measuring tools, and dust adhesion, etc. The elimination of static electricity is also a major problem to be ...

For example: Patent No. 88100556.8 discloses an antistatic fabric containing polyacrylonitrile fibers containing cuprous sulfide and rare earths. Patent No. 87104625.3 discloses a cuprous sulfide conductive polypropylene fiber, yarn, wool and preparation method. However, cuprous sulfide is easy to fall off from the fiber during washing and use, and the use effect is not ideal
