Finishing Process of Modified Nano TiO2 Photocatalyst on Cotton

Article Preview

Abstract:

A series of modified nanoTiO2 photocatalysts, nanoPC, was applied to cotton fabrics through a pad-dry-cure process. The effect of nanoPC dosage, the ratio of nanoPC to crosslinking agent, and curing conditions on the degradation of formaldehyde were discussed. The optimal finishing process of cotton fabric with nanoPC was determined as follows: 1%~1.5% photocatalyst, curing at 130°C for 5 minutes. Cotton fabric treated with the above process demonstrated over 90% degradation of formaldehyde, good washing fastness and soft handle, as well as little loss in breaking strength, tearing strength and polymerization degree.
