This work concerns the study of some important physical and mechanical properties of a wool fabric treated with a roll-to-roll atmospheric plasma jet equipment. The plasma pilot unit, based on a post-discharge technology, was equipped with an innovative plasma-to-fabric contactor, which promotes a relevant penetration of plasma through the fabric structure and geometrically defines the atmosphere. Wool fabrics were processed at three different velocities (1.3 and 6 m/min); the other process variables were kept constant. Tensile strength, elongation at break, surface thickness, wettability and air permeability increased after the plasma treatment, while several low-stress mechanical properties, strictly related to the handle, were not modified. SEM analysis was also carried out to better interpret the above macroscopic results. (C) 2009 Elsevier B.V. All rights reserved.

Abstract
This work concerns the study of some important physical and mechanical properties of a wool fabric treated with a roll-to-roll atmospheric plasma jet equipment. The plasma pilot unit, based on a post-discharge technology, was equipped with an innovative plasma-to-fabric contactor, which promotes a relevant penetration of plasma through the fabric structure and geometrically defines the atmosphere. Wool fabrics were processed at three different velocities (1.3 and 6 m/min); the other process variables were kept constant. Tensile strength, elongation at break, surface thickness, wettability and air permeability increased after the plasma treatment, while several low-stress mechanical properties, strictly related to the handle, were not modified. SEM analysis was also carried out to better interpret the above macroscopic results. (C) 2009 Elsevier B.V.
