Fibre saturation values have been determined at 90°c. for two groups of three similar disperse dyes on secondary cellulose acetate, cellulose triacetate and three cellulose acetates of intermediate acetyl value. The results have been correlated with the accessibility of the substrates and the hydrophobic character of the dyes and substrates. The rates of dyeing at 90°c. of two commercial dyes on the five yarns were found to decrease with increasing acetyl value, especially above 58% acetic acid content.
