AbstractSteam setting and dry heat setting was repeated alternately on nylon 6 fibers in which no further increase of crystallinity was expected, and the viscoelastic behavior of these fibers was investigated. The stress relaxation and thermal stress data indicate that steam setting weakens or breaks intermolecular bonds in the noncrystalline regions, while dry heat setting re‐forms the bonds. For unset and steam‐set nylon 6 fibers were γ‐irradiated at doses of about 107r, results of determinations of viscoelasticity, dye diffusion, and breaking in solvent show that crosslinking predominates with irradiation in vacuum and scission predominates with irradiation
