The study focused on novel surface modification technology: low temperature plasma, which is characterized by clean, high efficiency and energy-saving. Polylactic acid (PLA) non-woven materials were treated by this means under different treatment time. The SEM and FT-IR were used to observe the surface properties and internal structures of samples. Whether the wetting contact angle and the biodegradable property of materials were modified by low temperature plasma was discussed. The results indicated that with the increase of treatment time, the etching effect of plasma and some functional groups especial hydrophilic groups increased significantly. When they were only treated 3 minutes the wetting contact angle declined from 113.86° to 85.49°. Additionally, the hygroscopicity and biodegradability of materials were improved by low temperature plasma treatment.
