The dyeing operation produces significant decreases in the differential solubility of acrylic fibres with different percentage of relaxation. It has also been observed that the solubility differences found between substrates having different relaxation properties are largely preserved after a blind dyeing treatment has been carried out. The differential solubility technique using a mixture of dimethylformamide and water has been used to characterise their structure, and it has been found that acrylic fibres possess a good thermal memory.
