Cyclodextrins (CDs) called cyclic oligosaccharides are able to include functional ingredients in their cavity. Therefore, fixation of CDs to fibers enables the development of smart fabrics that release functional ingredients such as fragrances and moisturizing ingredients and/or remove bad smells. Here, we show some of research results about fixation methods of CDs to fibers using native CD and blocked polyisocyanate or using monochlorotriazino β-cyclodextrin (MCT-β-CD).
