FIXATION OF BETA-CYCLODEXTRINDERIVATES ON POLYESTER FIBERS

Syntheses of derivatives of beta-cyclodextrin are described which aime d at a partial substitution of OH-groups by hydrophobic moieties. Acco rding to such substitution it can he envisaged that those derivatives are applicable to polyester fabric treatment by conventional dispersio n dyeing methods, By applying such textile finishing agents it can be expected to impart hydrophilic properties to the fabric due to unsubst ituted OH-groups of the cyclodextrin but still remaining complexation ability due to the cyclodextrin inner torus. The success of anchoring of the derivatives onto polyester and methods for evidence of cyclodex trin derivatives on the polyester surface (iodine incorporation, fluor escence activity of dyestuffs included, FT-IR-spectroscopy) are given.
