Effect of atmospheric pressure air plasma treatment on desizing and wettability of cotton fabrics
نویسنده
چکیده
Atmospheric pressure air plasma has been used to treat grey cotton fabrics and the effect of treatment on their desizing and wettability properties is studied using the dielectric barrier discharge plasma with air and helium gas mixture. The weight loss due to etching has been determined by gravimetric method, the surface structure observed by SEM, the wettability studied by wicking action and the angle of contact test using water. It is observed that the rate of desizing increases when the fabric is pre-treated with plasma. This phenomenon of surface etching and chemical modifications can be used advantageously for industrial processing.

Drawing upon reflectance behavior of woodland colors involving dark brown in the UV-Vis-IR bands, two colored pigments were used to print cotton/polyester Co/PET goods. Inorganic nanoparticles of TiO2, ZnO and AL2O3 were also loaded onto the printing formulation. The reflectance profile of treated samples was studied using Jasco V-670 reflectance spectrophotometer. SEM analysis of printed fabri...
متن کاملAtmospheric Pressure Plasma Treatment for Grey Cotton Knitted Fabric
100% grey cotton knitted fabric contains impurities and yellowness and needs to be prepared for processing to make it suitable for coloration and finishing. Therefore, conventionally 100% grey cotton knitted fabric undergoes a process of scouring and bleaching, which involves the use of large amounts of water and chemicals, in order to remove impurities and yellowness. Due to increased environm...

The results of atmospheric pressure plasma treatments using diffuse coplanar surface barrier discharge (type of surface dielectric barrier discharge) on chromium surfaces are reported. A significant increase of surface wettability was observed after short plasma exposition. A quantitative value of surface wettability, i.e. the surface free energy, changed from 29 mJ/m to over 80 mJ/m. In time, ...
