Abstract
Atmospheric pressure plasma treatment is a surface modification technique, which can be used for surface finishing and pretreatment of textiles using a broad range of reactive gases. In this study, atmospheric pressure plasma was created using a mixture of nitrogen and oxygen and was applied to polypropylene spunbond fabric. Physical properties like moisture vapor transport, pore size distribution and tensile strength were evaluated to understand the effect of the plasma treatment on spunbond polypropylene. Chemical composition of the fabric before and after plasma treatment was analyzed by Fourier transform infrared spectroscopy. The spectra showed that oxygen and nitrogen containing groups were generated on the surface of the plasma-treated fabric. Scanning electron microscope was used to observe the surface morphology of the substrate. It is evident from the capillary flow porometer results, pore size increased after plasma treatment resulting in enhanced moisture vapor transport rate. No significant decrease in breaking load was observed after the plasma treatment.
