The deterioration from outdoor weathering of experimental wool fabrics differing in fiber fineness was measured by breaking strength, elongation at break, and crease recovery. With the amount of solar energy held approximately constant for each sampling period of each of the three consecutive sets of exposures, ambient temperature seemed to control the rate of deterioration.
Differences in strength and elongation among the fabrics were non-significant. The fine wools recovered from creasing significantly more than the medium wool.
