Local construction workers have to work outdoors for long hours under hot and humid weather conditions. To alleviate their strain, the research team led by Professor Albert Chan of  PolyU's  Department  of  Building  and  Real  Estate  (BRE) aimed   to   develop   suitable   clothing   that   met   industry specific requirements. After testing the properties of over 30   types   of   fabric   available   in   the   market,   the   team discovered   that   Coolmax   fabric   was   most   suitable   for producing the T-shirt. As for trousers, the team used a new generation  of  moisture-management  textiles  made  from nano-materials. Retro reflective strips are printed on both sides of the T-shirt and trousers to cater to the needs of the construction industry.

With excellent one-way transferability and  liquid  moisture  management  capacity, the  technology improves  fabric  breathability,  speeds  up sweat   evaporation   and   helps   construction   workers   to reduce heat stress.
