Studies on odor retention and antibacterial efficacy of non woven fabrics for technical textile applications

Abstract

In order to impart barrier property against microorganisms and control over the odor for corn foot treatment, three samples of 20/80 % polyester/viscose needle punched non woven fabric was treated with three different concentrations of Aloe vera & silver-nano solutions using pad- dry- cure method respectively. The samples were first treated separately with Aloe vera & silver-nano respectively and further treated with dual combination in a single bath. The treated samples were assessed for the antibacterial efficacy against Staphylococcus aureus and E-coli and the odor retention property was also analyzed. Samples treated with Aloe vera alone showed very low reduction rate in the number of bacterial colonies and exhibit high odor resistance. The samples treated with nano silver alone showed high reduction rate in number of bacterial colonies but showing low odor resistance. Dual finished sample treated with 100% conc. of Aloe vera and 7% conc. of nano silver showed higher reduction rate in number of bacterial colonies and having good odor resistance.
