“…25.0℃). 15–17 Such a design could prevent the possible heating delay caused by heating up the microenvironment between the sleeping bag and the feet. To avoid sweating-related discomfort, as well as saving energy, the high temperature threshold was set to be 3.0℃ lower than the lower limit of the feet temperature that would induce sweating-related discomfort sensation (i.e.…”

In this study, a novel smart electrically heated sleeping bag was developed by incorporating a proportional–integral–derivative heating control system into a traditional sleeping bag. The smart sleeping bag was aimed to maintain human feet temperature within the thermoneutral range (i.e. 25.0–34.0℃) by automatically adjusting the heat power to the feet region based on real-time human toe temperatures. Subsequently, the performance of the newly developed smart sleeping bag in improving human thermal comfort was investigated by human trials. Eight female subjects underwent two 8-hour sleep trials, that is, the smart sleeping bag with power turned on (SleepingbagHT) and the smart sleeping bag with power turned off (SleepingbagCON). All trials were performed at an air temperature of 6.1 ± 0.5℃ (i.e. the EN 13537 defined comfort temperature for females), relative humidity of 80 ± 5% and air velocity of 0.4 ± 0.1 m/s. It was found that SleepingbagHT could maintain both the foot and toe temperatures within the thermal neutral range as well as keep the local-, and whole-body thermal and comfort sensations in thermal neutral state throughout the 8-hour cold exposure. In contrast, linearly decreasing foot and toe temperatures and aggravated local-, and whole-body thermal and comfort sensations were detected in SleepingbagCON within a 4.5-hour cold exposure. It could thus be concluded that the smart electrical heating sleeping bag was able to provide wearers an 8-hour comfortable sleep in the studied cold environment.

“…Materials made from the fibre of different nature have different values of electrical resistance due to different water vapour absorption [12,18,25]. The effect of the accumulated moisture content in the textile laminates on their electrical resistance (at a voltage of U = 500 V) is shown in Fig.…”

The aim of this paper is to determine the influence of relative humidity on the comfort and electrical resistance properties of textile laminates in order to predict possible changes in footwear protection levels. Four textile laminates of different structure and fibre nature were selected for the study. It was determined that water vapour absorption of textile laminates strongly depends on the humidity of the storage environment. The absorption ability of laminates increases about 1.8 – 3 times as relative humidity increases from 65 % up to 95 %. The degree of increase depends on the textile laminate structure and the nature of the materials layers. The electrical properties of protective footwear can be influenced by the structure, thickness, relative humidity, and voltage of textile laminates. For textile laminates composed of natural and synthetic fibres and polymer foam as insulators, the resistivity increases with the thickness of the synthetic fibre and polymer layer. At low voltage (U = 100 V), the textile laminates tested became insulating materials, as the electrical resistivity exceeded the threshold values for antistatic materials in all relative humidity ranges. At high voltage (U = 500 V) the electrical resistivity of textile the laminates drops dramatically when the relative air humidity increases and the level of protection of the laminates depend on the amount of moisture absorbed and the nature of the layer materials. The laminates possessed insulating properties in environments of up to 65 % relative humidity. In a high humidity of the environment, the insulating properties of textile laminates turned to antistatic, except for laminate without a polymeric membrane, which became conductive.

“…One style will not fit all; therefore, it isn't easy to make a standard for appropriate athletic footwear [Nebo, 2005]. Moreover, athletic footwear requires robust construction, reliable closures, and a prolonged lifespan that withstands deterioration in any environmental conditions [Wang, 2013].…”

to experiment with different weaving structures with the same fabric construction and innovative patterns needed to fulfill customer needs for this product. However, it could affect the fabric's physical and mechanical properties. Hence, this study represents (4) samples produced from (Polyester filament, chenille P.E. (micro flat), and polyester/lycra by using double weave wadding structure techniques. The statistical analysis results for correlation coefficients show a direct correlation between the properties and the textile compositions of different pattern designs. Also, the statistically significant differences between the results are weak, which in turn is reflected in allowing the freedom of design using these different patterns by athletic footwear fabric designers and thus meeting the desires of customers for different designs for this type of athletic footwear without affecting on the mechanical properties of the fabrics involved in their manufacture. pattern designs; woven jacquard fabrics; athletic footwear Paper
