Finishes for protection against microbial, insect and UV radiation

Asim Kumar Roy Choudhury, in Principles of Textile Finishing, 2017

11.7 Antimicrobial fibres

Antimicrobial fibres (medical fibres) are manmade fibres with antimicrobial properties which include:

â—: inhibition of microbial growth,
â—: prevention of pus formation,
â—: acceleration of wound healing and reconvalescence and
â—: usage in the production of bandages, medical gauze, cotton wool and tampons.

11.7.1 Fibre modification through grafting

It is in this sector that the Institut Textile de France in Ecully has developed the so-called bio textiles. In these products, the chains of molecules containing antiseptic substances are grafted onto the base polymers of the raw fabric. The base polymers are activated by electronic rays; during the process, they are refracted in given positions, into which are inserted the first graft molecules. The chains of polymers, which grow laterally from the first molecule, confer on the fabric its bactericidal properties. In the event of direct contact, these fabrics act very rapidly against bacteria, and their bactericidal property remains intact even after washing (Shahidi and Wiener, 2012).
