Real evaporative cooling efficiency of one‐layer tight‐fitting sportswear in a hot environment

Abstract: Real evaporative cooling efficiency, the ratio of real evaporative heat loss to evaporative cooling potential, is an important parameter to characterize the real cooling benefit for the human body. Previous studies on protective clothing showed that the cooling efficiency decreases with increasing distance between the evaporation locations and the human skin. However, it is still unclear how evaporative cooling efficiency decreases as the moisture is transported from the skin to the clothing layer. In this stu… Show more

“…The fabric thickness influences water vapor transport and permeability (Bedek et al 2011). Wang et al (2014) evaluated the real evaporative cooling efficiency of one-layer tight-fitting sportswear in a hot environment and recommended that the thin vapor-permeable moisture-wicking fabric materials with a fabric thickness between 0.5 and 0.8 mm, such as Coolmax and sports wool, should be used for producing onelayer tightfitting sportswear because they could maintain a high evaporative cooling efficiency and also to allow a maximal evaporation rate. In the present project, the selected Coolmax fabric thickness is 0.62 mm, which accords with Wang et al (2014) recommendation.…”

“…In the so-called isothermal condition, a temperature gradient exists between the wet fabric Bskin^and the air (i.e., T sk,f <T air =T manikin ); the wet fabric Bskin^will gain heat from the environment (Wang et al 2011(Wang et al , 2014a(Wang et al , 2015b. Thus, the heat loss observed on manikin H manikin is not equal to the real energy H e used for water evaporation on the wet fabric Bskin^surface.…”

“…Also important to consider could be the effect of the saturated clothing, which was much colder than the surrounding clothing, likely coming into contact with the wearer as the person moved. This introduces a possible conduction heat transfer mechanism explored prominently in the work of Kerslake (1972), Havenith et al (2008), and Wang et al (2014). It is likely that the previously-studied efficiencies of the one-layer, tightly-fitting garments also contribute to the moisture-related heat transfer, especially where the garment is forced to come into contact with the skin by clothing, equipment, fitment, or drape.…”

“…Kerslake (1972) is cited as developing the first efficiency equations for evaporation from saturated clothing. This theoretical framework of evaporation efficiency was used by Wang et al (2013) andWang et al (2014) to formulate an evaporation efficiency of wet clothing. Tests were conducted under isothermal conditions with the clothing and skin in direct contact thus T o =T sk .…”
