Embodiment 1

[0038] Add 500ml of water, 50ml of ethanol, and 2g of pyrrole to the reaction flask and stir well, and then add 10g of acrylic fiber to soak for 4 hours. Then add 300ml of iron trichloride (0.5mol / L) aqueous solution and react at room temperature for 1 hour. After the fiber is taken out, washed with water and dried, a polypyrrole / acrylic composite fiber is obtained.

Embodiment 2

[0040] Add 500ml of water, 50ml of ethanol, and 2g of pyrrole to the reaction flask and stir well, then add 10g of polypropylene fiber and soak for 4 hours. Then add 300ml of iron trichloride (0.5mol / L) aqueous solution, and react at room temperature for 1.5 hours. After the fiber is taken out, washed with water and dried, a polypyrrole / polypropylene composite fiber is obtained.

Embodiment 3

[0042] Add 500ml of water, 50ml of ethanol, and 2g of pyrrole to the reaction flask and stir evenly, and then add 10g of chlorinated fiber soak for 4 hours. Then add 300ml of iron trichloride (0.5mol / L) aqueous solution and react at room temperature for 2 hours. After the fiber is taken out, washed with water and dried, a polypyrrole / chlorinated fiber composite fiber is obtained.

Abstract

The invention discloses polypyrrole composite fibers, relates to the use of the polypyrrole composite fibers in viral adsorption and belongs to the field of the use of functional fibers. Firstly, positive charges are introduced into fibers by an in-situ polymerization technique, so that the polypyrrole composite fibers have rich positive charges; and based on the principle that positive and negative charges attract mutually, viruses having negative charges are absorbed. The polypyrrole composite fibers have the advantages of no environmental and spatial limitation in use, cheap and readily available raw materials, simple production operation, light pollution, low cost, obvious virus absorption effect and good development and application prospects.

Description

Technical field [0001] The present invention relates to a functional fiber and its application, in particular to a polypyrrole composite functional fiber and its application in adsorbing viruses, belonging to the field of functional fiber application. Background technique [0002] Virus transmission is an important factor that causes the outbreak of infectious diseases. It is usually transmitted through droplets in the air and viruses in the water, posing a greater threat to human health and environmental safety. From December 1955 to January 1966, the hepatitis A epidemic in New Delhi, India and Shanghai, my country in early 1988, both traced the virus pollution of tap water and sea water. In recent years, the outbreak of SARS, avian influenza and influenza A has made people pay more attention to the study of virus adsorption and filtration. The current methods of virus removal include ultrafiltration membrane filtration, activated carbon adsorption, polymer flocculation precip...
