Description
Summary:•We treated wool/cashmere textiles with nitrogen atmospheric pressure plasma.•Wettability of the fabrics was increased.•Oxidation and/or removal of the external lipids layer was observed.•Higher tensile strength and minor changes in the tactile performance were detected. We performed atmospheric pressure plasma treatments of wool/cashmere (15/85%) textiles with a dielectric barrier discharge (DBD) in nitrogen. The chemical properties of the plasma treated samples were investigated with attenuated total reflectance Fourier transform infrared (FTIR/ATR) spectroscopy, X-ray photoelectron microscopy (XPS), and fatty acid gas chromatographic analysis. Changes in mechanical properties and tactile performance of textiles after the plasma treatment were determined using the KES-F system. The analyses reveal significant surface modification of the treated fabrics, which enhances their surface wettability.
