Study on the Subjective Thermal-wet Comfort Properties of "U" Shaped Polyester Knitted Fabric

U-shaped polyester fiber is a novel profiled fiber, its cross-section is similar to the H shaped cross-section of Coolbst. This kind of fiber has nice capillary effect. The fabrics made of it can absorb and transmit the sweat very quickly, and keep the body dry all the time. Compared with the pure cotton knitted fabric, the round shaped polyester knitted fabric and the cross shaped PTT knitted fabric, the U-shaped polyester fabrics have better thermal-wet comfort properties by testing the four subjective indexes of mugginess feel, dampness feel, stickiness feel and cold feel during body sweating.
