This study aims to determine the characterization of organdy silk fabric samples that continuously or repeatedly experience negative corona plasma radiations under atmospheric conditions. The negative corona glow discharge plasma is generated by connecting the point electrode to the negative pole and the positive pole field electrode to the DC high voltage source. In a square configuration, one hundred point electrodes with a distance between points of 1.3 cm were used in this study. Meanwhile, the field electrode was a copper sheet with 20 cm x 20 cm dimensions. Plasma irradiation was carried out between the point and plane electrodes at a distance of 1.6 cm, 1.9 cm, and 2.2 cm. The organdy silk samples, placed between the two electrodes, were irradiated continuously and repeatedly for 5, 10, 15, 20, 25, and 30 minutes. The drip test was carried out on the irradiated samples by dripping 1 mm of water in 12 places on the samples. SEM obtains microscopic images of the irradiated samples. Irradiation on organdy silk fabric samples changed the nature of the fabric from hydrophobic to hydrophilic. The longer radiation time makes the sample easier to absorb water. Repeated or continuous radiation treatment of the sample did not show any significant difference in the sample's ability to absorb water. The Scanning Electron Microscope test results of the sample showed some blisters and damage to the irradiated sample. When performing a continuous irradiation process, blisters and sample damage progressively occurred compared to when the samples were irradiated repeatedly. [ABSTRACT FROM AUTHOR]
