Study on moisture absorption performance of trilobal polyester fabric

This study was devoted to investigate the process of moisture absorption of trilobal polyester fabric. Trefoil polyester fabric and ordinary polyester fabric were selected,whose moisture absorption and wicking effect were tested using a homemade experimental apparatus by simulating different temperature and humidity conditions. The influence of the ambient temperature and humidity on the fabric moisture absorption performance was analyzed,as well as both the warpwise / weftwise wicking height and wicking rate. Research results showed that the moisture content of the fabric decreases with temperature rising, and increases with the increasing of humidity; the moisture absorption rate and equilibrium moisture content of trilobal polyester fabrics is greater than those of ordinary polyester fabrics,especially in low temperature and high humidity conditions; trilobal polyester fabrics have better liquid water transfer performance and higher wicking rate than ordinary polyester fabrics,and their warpwise wicking ability outperforms the weftwise.
