Abstract

The kinetics of washout of low-molecular-weight fractions from polycaproamide textile yarns during water-stabilization treatments has been studied. It has been found that the supermolecular structure of the yarns is considerably changed thereupon; the degree of crystallinity is increased, the size of the amorphous regions is reduced, the yarn porosity is increased, thereby increasing the rate of dye sorption, the yarn stress is reduced, and its shrinkage is lowered.
