| Abstract: | The dye uptake and creep deformation of commercial and heat-set poly(ethylene terephthalate) and nylon 6 fibers have been studied. On heat-setting, both dye uptake and creep are seen to decrease in the case of PET but show an increase in the case of nylon 6 fibers. This indicates that the rate-controlling factor for both these processes may be the same, and it is suggested that this factor could be sample morphology, in particular, the size and distribution of the amorphous volume in the fiber. |
