[ ${eta}$ ]-cyclodextrin having an inclusion property was applied to perfumed finishing of textile goods. ${eta}$-cyclodextrin was treated on the cotton fabric with polycarboxylic acid such as citric acid and butanetetracarboxylic acid. The fact that ${eta}$-cyclodextrin is covalently bound to cotton fabric with butanetetracarboxylic acid was confirmed by IR spectrum, TGA thermogram, and dyeing with basic dye. In case of citric acid, the result was not satisfactory, which was supported by laundering durability experiment. When cotton fabric treated with crosslinking agent and ${eta}$-cyclodextrin was compared with cotton fabric treated with only crosslinking agent, they gave similar values in dry wrinkle recovery angle. Perfumed finishing with ${eta}$-cyclodextrin including perfume was possible.
