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.
Fabric characteristics T-shirt fabrics (T1 and T2) and full-length pants (P1 and P2).
60% cotton blended with 40% polyester
100% cotton with Dry-Inside® technology
The design case in computer: body characteristics, activities and environmental condition.
The design case in computer simulation
65.6 kg and 168.5 cm
Activity and environmental condition
Seated relaxed (58 w.m-2), and (30°C, 50 %RH)-Standing activity (163 w.m-2), and (30.7°C, 65 %RH)- Standing activity (248 w.m-2), and (33°C, 54 %RH)-moving activity (229 w.m-2), and (34°C, 42 %RH)-moving activity (167 w/m2), and (32°C, 41 %RH)-recovery (58 w.m-2), and (31°C, 44 %RH)
Results and discussion
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.
