“…Fabric comfort may be divided into three main categories, including thermo-physiological comfort, sensorial comfort and psychological comfort. The thermal comfort of the fabric is mostly related to the movement of heat, air and moisture through fabric, and to keeping the wearer dry while sustaining a constant body temperature [23,24]. The comfort properties of the textiles require not be compromised during coating of the nanostructures onto the textiles.…”

The main aim of the present study was to investigate the effect of microwave irradiation time on the photocatalytic and physiological comfort characteristics of zinc-oxide-nanorod-coated cotton fabrics. An ultra-fast technique was employed to grow the zinc oxide nanorods on cotton fabrics using a microwave-assisted hydrothermal method. The axial (length) and lateral (diameter) growth of the zinc oxide nanorods was observed to increase with microwave irradiation time. The ZnO nanorods uniformly and entirely covered the cotton fibers. The surface morphology, topography and chemical characteristics of the ZnO nanorods were investigated by scanning electron microscopy (SEM), EDS analysis, X-ray diffraction (XRD), atomic force microscopy (AFM) and inductively coupled plasma-optical emission spectrometry (ICP-OES). The degradation of orange II dye under UV light irradiation was observed to assess photocatalytic self-cleaning and solution discoloration ability. The ZnO-nanorod-coated cotton fabrics exhibited excellent photocatalytic activity, as the stains of orange II dye disappeared predominantly within 4 h and the coated fabrics became almost white after 6 h. Analyses of thermal properties, water vapor permeability (WVP), air permeability and stiffness were also performed to investigate the physiological comfort of the ZnO-nanorod-coated fabrics. The thermal conductivity and thermal absorptivity were observed to increase with an increase in the size and density of the ZnO nanorods. Moreover, non-significant reductions in water vapor permeability and air permeability were observed with application of the ZnO nanorods. The stiffness of the ZnO-nanorod-coated cotton fabric increased due to the complete coverage of fibers by the uniform growth of the ZnO nanorods. The ZnO-nanorod-coated cotton fabrics also showed good washing durability and reusability.

“…[23][24]. Thermal comfort studies revealed that moisture transfer varied with different diaper types; the breathable film type has the biggest effect on water vapour permeability while top sheet of the diaper was the most important material in determining diaper thermal comfort properties; lastly wetting has increased thermal conductivity and provided a cool feeling [25][26][27]. Satsumoto and Havenith investigated the local ventilation in baby diapers and found that the ventilation affected by air permeability, construction and design features of the diapers [28].…”

The purpose of this paper is to provide an applied and objective analysis into heat transfer and mass transfer parameters such as relative water vapour permeability, thermal conductivity and thermal absorptivity as well as liquid accumulation of baby diapers which have critical importance on skin health using non-destructive Alambeta and Permetest instruments. SEM investigation was also carried out for characterization of breathable film layer of the diaper assembly. According to the water vapour transmission assessment, it was found that a few hours later, the composite diaper assembly becomes almost zero vapour permeable which results in discomfort and a poor breathability in baby diaper. It was also found that the liquid accumulation in diaper has increased in the course of time. The thickness of the diapers had an important effect on thermal parameters however production type of nonwoven top sheet and back sheet layers had a dramatic effect on these parameters.

Disposable diapers are very important in terms of babies’ health because they are in touch with the baby’s skin. Disposable diapers have sheets with different functions from each other. The main layers of disposable diapers are as follows: top sheet, absorbent layer and back sheet. The function of the top sheet is to pass the liquid to the lower absorbent layer whereas the function of the absorbent layer is to absorb the liquid. As for the back sheet, this layer keeps the liquid inside and prevents it from leaving the diaper. The back sheet is usually a nonwoven/ polyethylene (PE) film composite. Considering the babies’ health, breathable back sheets are mostly used in baby diapers to keep the skin drier. These have a positive effect on the baby’s skin, especially in terms of occlusion, diaper dermatitis. In this study, the performance properties of some commercial baby diaper back sheet layers have been investigated. For this purpose, weight, thickness, air permeability, water vapor permeability and water resistance tests were applied to back sheet samples with different fabric mass as breathable and non-breathable films. All back sheet samples are SMS nonwoven/ polyethylene (PE) film composites. Breathable samples have a larger fabric mass than non-breathable samples. For breathable samples, while increasing mass, air permeability and water vapor permeability decrease, water resistance increases. On the other hand, the same tendency is not seen in non-breathable samples. Breathable samples have higher air permeability, water vapor permeability, water resistance, and bursting strength than non-breathable samples. Consequently, the using of a baby diaper containing breathable back sheet is more proper in terms of baby’s skin health.
