Organdy silk characteristic changes by two-fabric surface point-to-plane atmospheric positive corona discharge irradiation

This study aims to determine the effect of two-fabric surface positive corona plasma radiation on the characteristics of organdy silk fabrics. The plasma generator uses a plasma reactor with a point-to-plane configuration. One hundred points stainless steel needles were used as the point electrodes and served as the anode electrodes. The cathode electrode, where the organdy silk samples were placed, was made of a copper board. The sample’s characteristics were analyzed using the Scanning Electron Microscope (SEM) method, the Fourier Transform Infra-Red (FTIR) method, the X-ray Fluorescence (XRF), the Mechanical strength test, and the water absorption time test. Sample irradiation by positive corona plasma discharge reduces the water absorption time and optimally after 20 minutes of irradiation. Mechanical strength testing of the organdy silk properties showed an increase in the tear resistance value of the irradiated fabrics increased compared to without irradiation at the optimum time of 20 minutes irradiation. The SEM examination showed that the surface structure changes of the fabric affect the wettability and the tear resistance of the fabric. The FTIR test showed changes in the fabric functional group structure, dominantly on O-H, C-H, C-O, and C-N compounds due to 30 minutes of plasma irradiation. Elemental composition changes of Al2O3, P2O5, and K2O were observed after 30 minutes of plasma irradiation. In conclusion, positive corona plasma radiation improves the microscopic characteristics of the organdy silk fabric.
