Assessing the thermal-moisture functional performance of two sets of work uniform by S-smart simulation
Extreme Physiology & Medicine volume 4, Article number: A90 (2015)
Construction workers are susceptible to heat stress in summer of Hong Kong. Wearing work uniform with good thermal-moisture functional performance (TMFP) is considered as one of the effective measures to protect workers from heat stress. However, there is a lack of scientific research to design workers' uniform based on heat-moisture engineering. This study aims to predict the TMFP of the selected fabrics by a S-smart system  under a stressful thermal environment.
The fabric characteristics of the examined knitted T-shirts (T1 and T2) and woven full-length pants (P1 and P2) were listed in Table 1. The S-smart system was adopted to simulate TMFP of clothing with the input parameters listed in Table 1 (fabric characteristics) and Table 2 (body characteristics, activities and environmental condition) . The simulation results were the human physiological responses, including the mean skin temperature (Tsk) and core temperature (Tc).
Results and discussion
The computer simulation in Figure 1 showed that T2 and P2 had better thermal-moisture performance in terms of predicted core and skin temperatures than T1 and P1, respectively. However, only a marginal difference was presented. This is might due to the excellent OMMC and lower AR of T2 and P2 compared to T1 and P1, promoting evaporative heat loss more efficiently.
The computer simulation results indicated that T2 and P2 can improve thermoregulation by decreasing the predicted core and skin temperatures and microclimate humidity as compared to T1 and P1, respectively.
