Inclusion complex of cyclodextrin (CD) with vitamin E (VE) or iodine was fixed onto a fabric using water based polyisocyanate as a crosslinker, and their durability and anti-oxidant activity or bactericidal activity were discussed. γ-CD complex was used for VE and α-, β-, or methylated β-CD complex were used for iodine. The poly(ethylene terephthalate) fabric was dipped into a suspension of a complex and polyisocyanate, and the fabric was cured to prepare a network of the complex and polyisocyanate. When a complex was fixed on the fabric with empty CD of its same kind showed higher fixed rate of VE or iodine. The fabric showed higher durability when a complex was fixed using treatin solution with lower ratio of a complex and higher ratio of a catalyst on polyisocyanate at higher curing temperature. For the fabric with the highest durability, 20 % of VE remained on the fabric even after 50-times wash. Anti-oxidant activity of the fabric was evaluated from the quenching of 2,2-diphenyl-1-picrylhydrazyl radical. The iodine-fixed fabric showed bactericidal activity after 10-times wash, which came up to the anti-bacterial standard of textile for general-use (orange ravel) of Japan Textile Evaluation Technology Council (SEK).
