Thermophysiological comfort of sonochemically synthesized nano TiO₂ coated woven fabrics

This work investigates thermophysiological comfort properties of sonochemically synthesized nano TiO₂ coated cotton and polyester woven fabrics. The obtained results were analysed on heat and mass transfer basis. Moisture management tester and Alambeta were utilised for moisture transportation and thermal evaluation. This study precisely investigates the effects of sonication on surface roughness of nano TiO₂ coated and uncoated samples. Ultrasonic acoustic method was applied to imbibe nano TiO₂ on fabric samples. Surface topography, morphology and the existence of nano TiO₂ on investigated samples were analysed by scanning electron microscopy and inductively coupled plasma atomic emission spectroscopy. In addition, standard test methods were applied to estimate physical and thermophysiological comfort properties i.e. thermal resistance, thermal diffusivity, heat flow, wetting time and accumulative one-way transport index of uncoated and nano TiO₂ coated samples.
