CYCLODEXTRINS APPLICATIONS IN THE TEXTILE INDUSTRY

摘要

The present paper reviews the state-of-the-art of the various cyclodextrins applications in the textile industry (e.g., in dyeing and washing processes, protective finishing, medical and technical textiles production, etc.). The experimental section presents the results obtained by the authors in UV protective and antimicrobial finishing of flax fabrics, through grafting with reactive monochlorotriazinyl-β-cyclodextrin. The method applied for obtaining inclusion compounds of monochlorotriazinyl-β-cyclodextrin with four guests (benzophenone, benzoin ethyl ether, ferulic acid, caffeic acid) is thoroughly described. The untreated and treated fabrics were evaluated by elemental analysis, Fourier Transform Infrared Spectroscopy, in the Attenuated Total Reflection Mode and UV-VIS-NIR spectroscopy. The microbiological tests, performed both before and after the finishing treatment, evidenced the antibacterial and antifungal properties of the compounds.
