PURPOSE:To form a rough surface, improve the adhesive property, deepen the color of dyed materials and improve the feeling and gloss of dyed materials, by etching a high polymeric sheetlike material continuously with a low-temperature plasma generated between specific asymmetric electrodes. CONSTITUTION:A high polymeric sheetlike material 1 is treated with a low- temperature plasma generated between internal electrodes in which the total suface area of electrodes 3 on the high voltage side is 0.1-2.5 times of the total surface area of an electrode 2 on the grounded side in an asymmetric electrode having one electrode of the electrodes 3 on the high voltage side with the total surface area of (1/500)-(1/10) of the total surface area of the electrode 2 on the grounded side. Preferably, the gas in discharging the above-mentioned low-temperatue plasma is oxygen or a mixed gas containing the oxygen, and the vacuum degree (p) is 0.05-1.0Torr with 1-10cm distance (d) between the electrodes 3 and 2 on the high voltage side and grounded side in the following relation: 0.05<p.d.<5 (TorrXcm). |
