Cyclodextrin (CD) was fixed onto a fabric using isocyanate as a cross-linker and their durability was discussed. The CD-polymer was insoluble on water, and reaction of CD with isocyanate was characterized with infrared spectroscopy. The poly(ethylene terephthalate) fabric was dipped into a solution of β-CD and isocyanate, and the fabric was annealed to fix CD. Weight decrease and CD content on the fabric was followed to evaluate the wash durability of the fabric. When CD was fixed with triisocyanate showed higher durability compared with the one fixed with diisocyanate. For the fabric with the highest durability, 60% of CD remained on the fabric even after 50 times washing. Absorption capacity of the CD on the fabric was evaluated to be 80% from the adsorption of phenolphthalein on a fabric.
