Description	The aim of this work is to study the changes in the properties of Polylactic acid (PLA) fabrics after plasma treatment at atmospheric pressure. Volume dielectric barrier discharge (VDBD) and diffuse coplanar surface barrier discharge (DCSBD) were applied to modify the PLA surface in ambient air using exposure times 1 - 10s. Various PLA fabrics in the weight range of 18 - 50 gsm were studied. The change in wettability and its aging were evaluated using the contact angle measurement by the Washburn method. A scanning electron microscope was used to measure the morphology changes.
