Heat treatment of nylon 6,6 in the temperature range of 100–175°C in the presence and absence of a nonionic surfactant (Triton X‐100) had little effect on the physical properties of the nylon, although the density of the nylon increased with increasing heat treatment temperature. The moisture regain value for the treated nylons did not change substantilly, whereas the overall wettability of the heat‐treated nylon in the presence of nonionic surfactant showed a marked improvement. Both heat treatment of the nylon alone or in the presence of surfactant had a substantial effect on the uptake of three 1,4‐substituted anthraquinone dyes on the nylon and on the resultant color of the dyed nylon.
