Antibacterial and Washing Resistance Improvement of Cotton Fabric Using Some Metal Oxides

Abstract

Cu2O, CuO, ZnO-microparticles with different size and morphology directly influences their antimicrobial potential. In this study, the possible improvement of the antibacterial and washing resistance up to 20 washing cycles performance of 100% cotton fabrics were investigated. At high temperatures, carboxylic acids form ester-type crosslinking with cellulose molecules and provide antibacterial activity. For this purpose, carboxylic acids such as BTCA and CA were used in this study.The purpose of this research was to evaluate 1,2,3,4-butantetracarboxylic acid (BTCA) and citric acid monohydrate (CA) as an crosslinking agent for washing resistance of 100% cotton textile substrates against, Staphylococcus aureus (ATCC 43300), Bacillus subtilis (NRRL NRS -744), Escherichia coli (ATCC 35218) and Klebsiella pneumoniae (ATCC 70063). Cupper oxide and zinc oxide were assimilated in the coating bath for the antibacterial property. BTCA concentration in the solutions influenced the antibacterial and washing properties of the cotton fabrics. The Fourier Transform Infra-Red -Attenuated Total Reflection (FTIR-ATR) spectra showed a new summit that confirmed the ester linkage formation and crosslinking reaction for application.
