    The relatively hydrophobic inside imparts beta-cyclodextrin the ability of forming complexes with many hydrophobic molecules. Numerous other molecules, such as different easily volatile molecules and ... pharmacological substances, can be introduced into its inside. To increase the penetration of beta-cyclodextrin into the textile material, the impregnation was carried out by means of ultrasonics. A cotton fabric was treated by beta-cyclodextrin in a VCX 750 ultrasonic instrument for 30 minutes. Since cyclodextrins are not reactive, they cannot be bonded on the textile material. In this investigation beta-cyclodextrin and p-toulensulfonil-chloride for the preparation of toulensulfonil derivative of beta-cyclodextrin were used. The reaction of cyclodextrin modification was monitored by UV-VIS and Raman-spectroscopy as well as by zone capillary electrophoresis. The presence of beta-cyclodextrin molecules on the textile substrate was determined by dyeing in reactions with phenolphthalein. By this method the presence of beta-cyclodextrin and the layer after treatment in the padder and by ultrasonics resp. was proved.
