The Study of Self-Cleaning Properties of TiO2 Coated on Cotton Fabrics

Abstract

This research study about self cleaning activity of TiO2 coated on cotton fabric. TiO2 nanoparticles is known as good semiconductor which have photocatalytic properties. Cotton fabric was coated by TiO2 to produce self cleaning textiles. Coating of TiO2 nanoparticles on cotton fabrics was carried using a pad-dry-cure method with citric acid binder variation composition of 25%, 30%, 35%. And 40%. Characterization of TiO2 coated fabrics was studied using EDX analysis and stiffness test, while self cleaning activity of coated fabrics was studied using color aging test. The results showed that the stiffness value of coated cotton fabrics were wasn’t change significantly. The EDX analiysis of the cotton fabric coated with TiO2 nanoparticles showed more Ti were bonded to the fabric which is coated with 25% binder. Self cleaning activity showed that cotton fabric coated TiO2 with composition 25% had the largest self cleaning activity. Keywords— cotton fabrics, self cleaning activity, TiO2
