Abstract

The colors of polyamide fibre obtained in dyeing with α-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 α-CD is much higher than for samples without the additive with an increase in the temperature. In spectrophotometric determination of complexation in the dye—α-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. α-CD thus acts as a process booster.
