Textile fabrics have been diversified in their appearance and handlings, and those with various other sensitivities are need.Therefor, the surface and reverse modification, especially, etching reaction and implantation reaction of textile fabrics by low temperature plasma treatment, which modify surface properties without change of bulk properties, has been investigated ; and the basic aspects of the hydrophily treatment and water-repellent treatment of textile fabrics have been obtained from the discussion.Air gas and CFィイD24ィエD2 gas were used for analyzing hydrophily property and water-repellent of plasma treatment. The fabrics were folded in half so that the surface and the reverse of the fabrics were not interacted by plasma treatment. The effect of the treatment were assessed by the contact angle and ESCA.Main results are reviewed briefly as follow. When one side was treated by air gas and then its reverse side by CFィイD24ィエD2 gas, on side presented hydrophile property and the other side was water-repellent property. However, when order of each gas treatment was quite adversely applied, both the surface and the reverse was presented hydrophile property.From this fact, it has been cleared that ; 1) it is necessary to clarify that which atoms can be competitively and firmly bonded in the plasma treatment, 2) especially, the above point should be considered as most important when bilateral fabrics are made experimentally, and 3) useful findings were observed in a tendency of molecule-desert caused by electronegativity.In dyeing of plasma treatment fabrics, hydrophily side was dyed in heavy shade while water repellent side in pale shade, without affecting nothing both hydrophile and water-repellent properties. In consequence, the plasma treatment fabrics were obtain reversibly effect in different hue. Performance of these treated fabrics will assure the realization of its new processing of plasma treatment.
