Specimens exposed in the polar regions were general fibers（ nylon 6, polyester, acryl, cotton, wool and silk） as clothing materials set on Syowa Station in the Antarctic from 2005 to 2006, which were carried back to our group by the staffs of Wintering Party of the 46th and 47th Japanese Antarctic Research Expedition. On the surface of fibers exposed in the Antarctic were observed the disappearance of the skin parts and the oligomerization. It was confirmed that more crystallization appeared on the exposed natural fibers than the synthetic ones from observation by scanning electron microscopy. Such recrystallization was estimated to be caused by rather the influence of water and low temperature than intense ultraviolet irradiation. The experiment under the cold-setting conditions suggested that water at low temperature enhanced crystallization on surface of fibers.
