Abstract

Himadri Tanaya Mahanta

In this study, synthesis and optimization of titanium dioxide nanoparticles were carried out at room temperature by sol-gel technique using Box-Behnken design of experiment. Titanium dioxide nanoparticles were characterised using UV-visible spectrophotometer in which the band gap energy was determined as 3.31 eV, particle size analyser (PSA) analysed size of nanoparticles as 250 nm and scanning electron microscope (SEM) showed uniform distribution of nanoparticles on surface of fabric. The titanium dioxide nanoparticles were applied on cotton fabric through pad-dry-cure method to develop self-cleaning property on cotton fabric. The stain degradation property was evaluated initial and after 20 washes and determined significant decrease in K/S value with increase in concentration of nanoparticles. There is no significant effect on inherent properties of fabric to be found.
