Quantification of cyclodextrins fixed onto cellulose fibers

Cyclodextrins are fixed onto different textiles using conventional finishing technologies to create new materials with a wide range of applications. One important problem in the textile finishing is evaluation of the amount of cyclodextrins accessible for complexation with guest substances. This research investigated the coordination and adsorption properties of cellulose materials with fixed monochlorotriazine substituted beta-cyclodextrin for different primary, secondary and tertiary volatile aliphatic amines. The textiles showed high ability to complex formation from the gas phase due to molecular recognition between internal cyclodextrin cavity and hydrocarbon chains of the amines. The complexation reaction with cyclohexylamine is suggested for quantitative determination of the accessible cyclodextrins fixed on the surface of cellulose fibers.
