Chemical Damage in Wool

Abstract

The changes in the stress-strain properties of wet wool fibers upon exposure to solutions of varying alkalinities are reported. Cystine-lanthionine ratios found in these samples as interpreted from paper chromatogrms are compared with changes in stress- strain properties. The presence of lanthionine m wool boiled in a solution at pH = 4.5 and in wool exposed to temperatures of 150° C. under atmospheric conditions is noted.
