Resum


This paper describes the behaviour observed during integration dyeing of a cross-wound wool package with an anionic dye of the supermilling type. The relationships between levelness and the variables dosing time, temperature, liquor flow rate and dye concentration in the fibre, at pH conditions corresponding to the isoelectric point of wool were examined. An increase in the flow rate and of the dye concentration during the dosing was found to improve dyeing levelness, while an increase in temperature and a decrease in dosing time impaired levelness.
