The colors of poly amide fibre obtained in dyeing with a-cyclodextrin (CD) additive are uniform and saturated.This effect is also obtained on wool fibre and wool-polyamide fibre blend.It was found that the dyeability of the samples with a-CD is much higher than for samples without the additive with an increase in the temperature.In spectrophotometric determination of complexation in the dye-alpha-CD aqueous system,it was found that the dyeability of the samples was highest in a 1:1 ratio than with the standard dyeing method.alpha-CD thus acts as a process booster.
