Silver nanoparticles which are highly effective in killing bacteria have been applied in many fields. One of its practical applications is that the silver nanopartcles are applied in textiles for creating antibacterial fabric. In this work, the cotton fabrics were immersed in nano silver colloid (diameter = 7-11 nm) which is prepared by polyol process with microwave heating. The antibacterial performance of the antibacterial cotton fabric was tested for different concentration of nano silver colloid, contact time germs, and washing time. It was found that antibacterial activity increased with the increasing concentration of nano silver colloid, contact time germs and with the decreasing washing time.
