The Grafting of Per-(2,3,6-O-allyl)-β Cyclodextrin onto Derivatized Cotton Cellulose via Thermal and Atmospheric Plasma Techniques

In recent years, cyclodextrin applications have been expanding to include textile finishing, providing new and unique functionalities to the fabric substrates. In this work the grafting of Per-(2,3,6-O-allyl)-beta cyclodextrin by plasma and conventional thermofixation methods is described. The fabric substrate was cotton and activated by the surface modification of the fibers by the synthesis of iododeoxycellulose, cellulose peroxide, and a cellulose diazonium salt. Several plasma machines and conventional thermal techniques for fixation were studied. Iododeoxycellulose gave the best results by thermofixation and the in situ mode of the APJeT atmospheric plasma machine. Linoleic, ricinoleic, oleic acids were included in the grafted cyclodextrin fabrics as possible wound healing agents. The cyto-compatibility of the treated samples either included or un-included with fatty acids shows promising results.
