Preparation of Antibacterial Cotton Fabric using Chitosan-Silver Nanoparticles

Abstract

The aim of this study was to prepare antimicrobial cotton fabric using chitosan-silver nanoparticles (CS-AgNPs). CS-AgNPs were used as finishing agent for textile made from 100 % pure cotton. AgNPs used in composite were prepared by Turkevich method and CS-AgNPs was synthesized by mixing chitosan solution with silver nanoparticles. Fourier transform infrared (FTIR) spectrometer technique supported the formulation of CS-AgNPs. Cs-AgNPs crystalline peaks obtained by X-ray Diffraction were in perfect agreement with to the JCPDS card no. 89-3722. Two gram negative bacteria Escherichia coli, Pseudomonas aeruginosa and two gram positive bacteria Bacillus cereus, Staphylococcus aureus were used to test the bacterial efficacy of synthesized AgNPs and CS-AgNPs. SEM micrograph of cotton fabric revealed the presence of CS-AgNPS on the surface. The presence of small amount of silver nanoparticles in the composite was enough to enhance antibacterial activity significantly as compared with pure chitosan.
