Studies were conducted on durable and rechargeable antibacterial properties of spacer knitted fabrics. To achieve a durable and rechargeable antibacterial properties, spacer fabrics made of cotton, polyester-cotton (65-35) and polyester-viscose (25-75) were treated with dimethylol dimethyl hydantoin (DMDMH), followed by chlorine bleaching. The methylol groups on DMDMH can either form cross-links with cellulose with both functional sites reacted or grafted onto cellulose with only one reactive site consumed. In each test, cotton, polyester cotton, polyester viscose spacer was separately exposed to treatment baths in two stages. Different concentrations of DMDMH in primary and chlorine in secondary finishing bath, pH, temperature, in both baths were optimized. The biocidal efficacy of such spacer fabrics is high against Staphylococcus aurous, a gram-positive bacterium and Escherichia coli, a gram-negative bacterial according to AATCC test method 100-1993. The findings show that the washing fastness of antibacterial finishing is acceptable and the biocidal effect persists through at least 50 machine washing cycles and can be regenerated by exposure to diluted chlorine solutions. A comparison between the FTIR tests after and before antibacterial finishing shows the covalent bonds between dimethylol dimethyl hydantoin (DMDMH) and spacer fabrics.
