An inert and two non-polymerizing gases were used to produce plasma. Effects of atmospheric plasma treatment on some physical properties of polyamide fabrics were investigated. Thermal, low-strees mechanical and air permeability properties of different plasma treated polyamide fabrics were evaluated in this study. It is thought that changes in these properties are closely related to their topographycal changing thanks to plasma treatments. Thermal properties have been closely related to the amount of air trapped between the yams and fibers. It is thought that physical and final properties of polyamide fabrics can be improved by using plasma treatments, and atmospheric plasma treatment is an alternative for ecological treatments.
