The main aim of the present study was to investigate the effects of ultrasonic irradiation on thermophysiological comfort properties of TiO-coated fabrics. The results were evaluated on the basis of heat and mass transfer as well as air permeability performances. Alambeta, a permetester, an air permeability tester, and a moisture management tester were used for thermal evaluation and air and moisture transportation, respectively. Hundred percent pure cotton and polyester woven fabrics were used for this study. Moreover, the study explains the effect of sonication on surface roughness of textile woven fabrics. TiO nanoparticles were deposited onto selected fabrics by sonication. Surface topography, changes regarding surface roughness, and the presence of nano TiO were evaluated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, X-ray diffractometry (XRD), and inductively coupled plasma atomic emission spectroscopy (ICP-AES). Furthermore, standard test methods were carried out to evaluate physical and overall thermophysiological comfort properties, i.e., thermal conductivity, thermal absorptivity, relative water vapor permeability, absolute evaporative resistance, air permeability, and overall moisture management capacity of TiO-treated and untreated samples.
本研究的主要目的是探究超声辐照对涂覆二氧化钛织物热生理舒适性的影响。基于传热传质以及透气性能对结果进行评估。分别使用Alambeta、透气仪、透气度测试仪和水分管理测试仪进行热评估以及空气和水分传输测试。本研究采用了100%纯棉和聚酯机织物。此外,该研究还阐述了超声处理对纺织机织物表面粗糙度的影响。通过超声处理将二氧化钛纳米颗粒沉积在选定的织物上。通过扫描电子显微镜(SEM)、能量色散X射线(EDX)分析、X射线衍射仪(XRD)和电感耦合等离子体原子发射光谱仪(ICP-AES)对表面形貌、表面粗糙度变化以及纳米二氧化钛的存在情况进行评估。此外,还采用标准测试方法评估了二氧化钛处理和未处理样品的物理和整体热生理舒适性能,即热导率、热吸收率、相对水汽渗透率、绝对蒸发阻力、透气度和整体水分管理能力。
