The evolution of dye absorption and fine structure variations due to heat treatment in high‐bulk yarns was studied. Two acrylic fibres of different commercial origin were employed. Using these, the following yarns were spun: 100% relaxed (N), 100% retractile (R), 55:45 N/R and 45:55 N/R. The evolution of fibre microstructure induced by the dyeing process was studied through the differential solubility technique in mixtures of dimethylformamide and water.
