Sorption isotherms of reduced and succinylated wool and then desalted completely or partially were obtained and the moisture sorption behaviors on these treated wools were compared with those on reduced and intact wools in order to clarify the influence of succinylation on the moisture sorption. COO.M+ group introduced into wool keratin by succinylation is more effective to improve the moisture sorpability than decrease of the crystallinity. OH and NH2 groups which are reaction sites in succinylation, contribute to the moisture sorption slightly more than COOH group. The sorption behaviors on these treated wools were explained by BET multilayer sorption theory combined with polymer solution theory.
