Abstract

New reactive anti-uv finish DHUV-1 is an ultraviolet light (uv) absorber suitable for uv-proofing finishing of cotton fabrics. It has strong absorption effect on UVB (280~315 nm) band uv and good washing resistance. Its application is presented. The results showed that DHUV-1 has a process curve similar to that of the K type reactive dyes, and is suitable to be used in one-bath finishing with K type reactive dyes. When the dye dosage is 0.3% and DHUV amt. 1%, the soda ash amt. 20 g/L and sodium chloride amt. 70 g/L are recommended to obtain good uv-proofing effect and acceptable shading.
