The Detection of Modification in Animal Fibers: II. Tensile Recovery at 65 % R. H

Methods are described for measuring parameters of the tensile recovery of animal fibers. The effects of fiber crimp on these measurements, and the interpretation of the data obtained with crimpy fibers, are discussed. Data are presented on the fiber-to-fiber variation in tensile recovery and on the effects of various chemical treatments. For wool fibers from a common source there is very little fiber-to-fiber variation in tensile recovery.
