Interaction of polyamide 6 fibres with some organic compounds vis. phenol, ethanolamine, ethylamine, and formaldehyde was thoroughly investigated. Some changes in the internal polymer fine structure as well as in the fibre mechanical properties were attained. Characterisations of the modified substrates were performed through measurements of the dynamic length shrinkage, change in weight, differential thermal analysis, x-ray diffraction, thermogravimetric, viscosity analyses and dyeability. The treatment revealed a decrease in the glass transition temperature, change in crystallinity, d-spacing and crystal perfection index. Dyeability with acid and disperse dyestuffs was also progressively increased.
