Dyeing of nylon 6 (polycaprolactam) film from trichloroethylene and perchloroethylene with several purified dyes is reported.
Rate curves and diffusion data indicate that the sorption of disperse dyes by nylon from these solvents is slower by 50-100 times their sorption by polyester.
Dyes with polar substituents give higher partition coefficients, probably due to their lower solubility in the solvents and higher solubility in nylon 6 than in very nonpolar dyes. Very few of the dyes studied have partition coefficients which would make exhaust dyeing desirable; however, the possibility of synthesizing dyes or finding dyes which would have application to nylon does appear to exist.
