in the reported experiments, effects of chemical modifications such as mercerization (with and without stretch) and crosslinking (with hcho and dmdheu of various concentrations) on mechanical properties such as dynamic (sonic) modulus, immediate elastic recovery (ier), work recovery (wr), and crease recovery angle (cra) of yarn samples were studied. while slack mercerization reduced the dynamic modulus and the recovery parameters, stretch during mercerization brought about a profound increase in their values. the dynamic modulus and recovery parameters also increased progressively with the severity of crosslinking in hcho and dmdheu. a high degree of linear correlation existed between the dynamic modulus and ier, wr, and cra for samples treated with a given reagent; however these relationships were specific to the reagent. 22 refs
