Environmentally friendly plasma pretreatment for preparation of self-cleaning polyester fabric with enhanced deposition of TiO2nanoparticles
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 3
Abstract
Tio2 nanoparticles (NTO) were loaded on plasma pretreated polyester fabric during a pad-dry-cure process. The influence of plasma treatment on the TiO2 nanoparticles adsorption and surface properties of the polyester fabric was investigated. Thermal treatment was used to determine the residual NTO on the surface of the fabrics and indicated more residual NTO after ten washing cycle for plasma and NTO treated samples. Acceptable selfcleaning and UV protection properties obtained on NTO treated samples especially in plasma pretreated ones due to the photocatalytic activity of NTO. Vertical wicking results showed that the hydrophilicity of NTO treated samples was improved. It was found that plasma treatment as a surface modification method increased the NTO adsorption on polyester fabric due to increase in surface functional groups on the polymeric chain. SEM images also showed an almost even distribution of the nanoparticles on the surface of the fabric.
