The mechanism of backtanning of nylon 6 fibers has been studied by X - ray diffraction, dynamic mechanical properties and rate of dyeing. The following results were obtained.
(1) The (200) lattice spacing and crystallite size increased by backtanning treatment, but the (002) lattice spacing decreased.
(2) The temperature of the peak of tanσ of nylon 6 fibers treated with backtanning was higher than that of the untreated fibers.
(3) The rate of dyeing of disperse dyes into the nylon 6 fibers treated with backtanning was lower than that of the untreated fibers.
