| Cotton and silk fabrics are preferred for their excellent wearing properties. But they not only have the disadvantages of the poor resistance to bacterial, and the formation of disagreeable odor but also they are easy to wrinkle during wearing. In this paper, chitosan/ citric acid andβ-cyclodextrin/citric acid were used to impart the good deodorant and anti-crease properties to cotton and silk fabrics through pad-dry-cure finishing. Through the analyses of the changes in the properties of fabrics finished and unfinished, the conclusions were drawn as follows.(a) After finished by chitosan/citric acid andβ-cyclodextrin/citric acid, cotton and silk fabrics showed the higher percentage of deodorization for ammonia, formaldehyde, methanol and dimethylbenzene, especially for ammonia. Also, the percentage of deodorization was maintained over 85% after washing 5 times. The deodorant ability of fabrics finished byβ-cyclodextrin/citric acid was better than that finished by chitosan/citric acid. Besides, the deodorization percentage of silk fabric was higher than that of cotton fabric under the same condition of finishing.(b) The crease-resistance of cotton and silk fabrics finished by two methods was improved significantly. Furthermore, the wrinkle recover angle of the fabrics finished byβ-cyclodextrin/citric acid finishing was higher than that by chitosan/citric acid, and the increases in the wrinkle recover angle of silk and cotton fabrics were 112o and 82o, respectively, in comparison with unfinished fabrics.(c) The tensile strength, whiteness and softness of fabrics were slightly decreased after finishing. The decrease in the tensile strength of fabrics finished byβ-cyclodextrin/citric acid was lower than that finished by chitosan/citric acid, and the strength decrease for cotton fabric was higher than that for silk fabric under the same condition of finishing.
