Specimens exposed in the polar regions were general fibers（ nylon 6, polyester, acryl, cotton, wool andsilk） as clothing materials set on Syowa Station in the Antarctic from 2005 to 2006, which were carried backto our group by the staffs of Wintering Party of the 46th and 47th Japanese Antarctic Research Expedition. Onthe 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 syntheticones from observation by scanning electron microscopy. Such recrystallization was estimated to becaused by rather the influence of water and low temperature than intense ultraviolet irradiation. The experimentunder the cold-setting conditions suggested that water at low temperature enhanced crystallization onsurface of fibers.
