Thermophysiological comfort of sonochemically synthesized nano TiO2 coated woven fabrics

Abstract

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.

Development of antibacterial and UV protective cotton fabrics using plant food waste and alien invasive plant extracts as reducing agents for the in-situ synthesis of silver nanoparticles

“…Air permeability decreases for all samples where in-situ synthesis of AgNP on cotton was performed, which is due to the presence of nanoparticles on and in the fibres. The same was found by others (Ali et al 2018;Shaid et al 2014;Noman et al 2020;Ugur et al 2010;Jiang et al 2015). Although the air permeability is reduced for the samples with in-situ formed AgNP, the values are not much lower compared to the untreated sample, implying that the functionalised cotton fabrics still provide good comfort to the potential user.…”

Classification of Textile Polymer Composites: Recent Trends and Challenges

“…Comfort evaluation is a noteworthy parameter in terms of fabric overall performance [ 47 , 48 , 49 , 50 , 51 ]. Majority of machine learning algorithms were applied on fabric’s thermophysiological and sensorial comfort.…”

Photocatalytic Behaviour of Zinc Oxide Nanostructures on Surface Activation of Polymeric Fibres

“…As a semiconductor, ZnO has high thermal conductivity, high exciton binding energy (60 m eV), high electron mobility and wide band gap, i.e., 3.2–3.4 eV [ 19 ]. The potential of photocatalytic activity of nZnO expands its scope in biomedical [ 20 ], industrial [ 21 , 22 ], catalysis [ 23 , 24 ], coatings [ 25 , 26 ], sensors [ 27 , 28 ], textiles [ 29 , 30 ] and energy conversion devices, i.e., fuel and solar cells [ 31 ]. nZnO has also been used in personal (sunscreen) and beauty care (cosmetics) products due to excellent ultraviolet (UV) absorption properties.…”
