The Effect of Strain on the Electrical Resistance of Keratin

Abstract

The change of resistance with time after the application of various strains has been examined at 90% RH and 20° C. for keratin fibers. There is an initial instantaneous rise of resistance much greater than that due to a dimensional change, which is related to the strain, followed by a decrease in the resistance caused by the uptake of water vapor from the surrounding atmosphere. A further stage was observed during which the resistance rose as excess water vapor left the fiber.
