Abstract

The effect of corona-discharge treatment on the structure and physical properties of thermally bonded fabrics has been studied with different conditions such as electrical power and treating time. The physical properties investigated were weight loss, tensile strength, reflectance, wettability and drapability. The morphological structure of samples was also observed by using SEM. As the result of this study, the surface structure of corona-treated fabrics showed a considerable change with increasing the electrical power and treating time. It was observed that the increase of surface roughness in thermally bonded fabrics was closely related to physical properties; wettability, reflectance and tensile strength. The weight of corona-treated fabrics has slightly decreased with increasing the electrical power and treating time, but the drapability has improved due to the change of the structural shape affected on the surface roughness of corona-treated fabrics.
