In this research, some physical, mechanical and antibacterial properties of melt-spun nylon 6/nano-silver multifilament yarns have been studied. Characteristics of nano-composite multifilament yarns were studied by tensile testing, scanning electron microscopy, transmission electron microscopy, differential scanning calorimetry and energy dispersive X-ray. The antibacterial efficiency of produced yarns was estimated by quantitative AATCC-100 test method. According to the results, it was concluded that, sample yarns with 0.5—1 wt% content of nano-silver possessed acceptable antibacterial activity and their mechanical properties did not change significantly.
