✦ Synopsis

Crystalline content, crystelline orientation, and long period of heat-aet nylon 6 fibera were inveatigated. Fibera subjected to dry heat setting or ateam setting, have x-ray diffraction patterne which auggeet that an increaae of cryutallinity occura on treatment, eapecially in the caae of steam setting. The degree of crystalline orientation doea not decrease greatly in either dry heat setting or steam setting. Therefore, the increaaed dyeability of nylon 6 fiber on heat setting is not attributable to a decrease of orientation of cryatallites. The large increase of long period produced by steam setting corresponds to the increase in density noted.
