Abstract

The Dimethyl hydantoin (DMH) – Isocyanatopropyltriethoxysilane adduct was prepared and applied onto the fabric using pad – dry – pad – dry – cure method. The treated fabric is then chlorinated using NaOCl (6% and 10%) to impart the antimicrobial properties. The treated fabric surface and the chlorine percentage present at the surface of the fabric are evaluated using SEM- EDX and peak of NCO was determined using FTIR analysis. The fabrics were tested for antimicrobial properties using ATCC 2695 gram positive bacteria Staphylococcus aureus and ATCC 8739 gram negative bacteria Escherichia coli. The treated samples provided very good antimicrobial properties even after three vigorous soap washings. The fabric durability properties such as tensile strength, abrasion resistance, and stiffness and comfort properties such as thermal resistance and evaporative resistance were also measured.
