For improvement of the hydrophilicity and dyeability, the plasma polymerization of acrylic acid onto polyester fabric was applied in an inductively coupled glow discharge system. During glow discharge, oxygen was added to increase the carboxyl and hydroxyl group of platoma polymerized acrylic acid (PP-AA). The surface characteristics of PP-AA/polyester fabric was investigated at various discharge power and pressure of oxygen. The chemical structure of PP-AA was similar to poly(acrylic acid). Owing to the excellent hydrophilicity of the PP-AA, the wettability of PP-AA/polyester fabric was improved. It was further improved if oxygen was introduced during the plasma polymerization. Dyeability of PP-At/polyester fabric with basic dye was improved due to the presence of the carboxyl group of PP-AA.
