The purpose of this study is to investigate the adsorption rate, adsorption quantities and the UV-Cut effects of cotton fabrics treated with several UV absorbents. The result of this study were as follows: cotton fabric treated with 2,2`-dihydroxy-4-methoxy-benzophenone shows more efficient than ones treated with 4-aminobenzoic acid and 2-hydroxy-1, 4-naphthoquinone in UV absorption. This may be due to the absorption of UV light by formation of intra molecular hydrogen bond. The formation of hydrogen bonds between hydrogen atoms of two hydroxy groups and one oxygen atom of carbonyl group in 2, 2`-dihydroxy-4-methoxy-benzophenone would be easier than that of the other absorbents. The adsorption isotherms of 4-aminobenzoic acid and 2-hydroxy-1, 4-naphthoquinone were similar to Freundlich type, while that of 2, 2`-Dihydroxy-4-methoxy-benzophenone was Henry type. Cotton fabrics treated with Antifade MC-100 and UV Cut E-2 were just alike in UV absorption, but Antifade 8001 was inferior to the others.
