Fixierung von β-Cyclodextrinderivaten auf Polyesterfasermaterial

Fixation of β-Cyclodextrinderivatives on Polyester Fibres . Syntheses of derivatives of β-cyclodextrin are described which aimed at a partial substitution of OH-groups by hydrophobic moieties. According to such substitution it can be envisaged that those derivatives are applicable to polyester fabric treatment by conventional dispersion dyeing methods. By applying such textile finishing agents it can be expected to impart hydrophilic properties to the fabric due to unsubstituted 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 cyclodextrin derivatives on the polyester surface (iodine incorporation, fluorescence activity of dyestuffs included, FT-IR-spectroscopy) are given.
