Three-dimensionally ordered macroporous titanium dioxide (3DOM TiO2) was prepared by a sol-gel methodusing poly(methyl methacrylate) as a template. The synthesized 3DOM TiO2 was finished on poly(ethylene terephthalate)and poly(lactic acid) fabrics by a pad-dry-cure method to enhance self-cleaning properties. Discoloration of curcumin,carmoisine and methylene blue stains on finished fabrics under UVA irradiation was examined to evaluate its self-cleaningabilities. The results showed that 3DOM TiO2 on the finished fabrics could diminish the stains in a higher degree as comparedto the unfinished fabrics and fabrics finished with TiO2 nanoparticles. Dyeing properties of polyester fabrics with C.I. Disperse Red 60 were slightly affected by 3DOM TiO2. Color strength (K/S) and wash fastness of the 3DOM TiO2 finishedfabrics were a little lower than the unfinished counterparts.
