<p>Hydrophobic polymer materials (10) having improved dyeability with water-based dyes are prepared by treating a hydrophobic polymer (10) with a glow discharge plasma (20) generated from working gases (22) selected from the group consisting of SO2, O2, N2, He, H2, CO2, CF4, NO, N2O, 2-Hydroxypropyl Methacrylate (HPMA), air or combinations thereof, in which a treated material (10) comprises a hydrophobic inner cores (110) and a hydrophilic outer sheath (120) having polar functional groups (130). A method of treating hydrophobic materials (10) using a glow discharge plasma (20), preferably at high pressure (e.g., about 50 Torr or greater), thereby modifying the active surface characteristics of the polymer (10) to contain polar functional groups (130) is also presented.</p> |
