Antibacterial finish for fabric used in helmet interlining

Abstract

Development of bacteria free interlining fabric for helmet interlinings remain mandatory in today’s competitive and fast growing technical world since our government is imposing the need of safety through implementation of strict rules that all motor cycle riders wear helmet and it’s our duty that we wear a hygienic helmet to protect our health. In this study, presence of bacteria in the used helmet swabs under aerobic bacterial culture method has been analysed and determined that two bacterium namely staphylococcus aureus and klebsiella pneumonia were present in it. As nano silver is widely know for its antibacterial activity, used it in our study for applying antibacterial finish on polyester fabrics through pad dry cure technique. The treated samples (unwashed) show a very good zone of Bacteriostatics against identified bacteria. The washed sample possesses antibacterial activity upto 20 washing cycle, which depicts clearly that the acrylic binder used for finishing retains the antibacterial activity of the agent.
