Moisture absorption and release of profiled polyester and cotton composite knitted fabrics

Composite yams were spun using profiled polyester fibers and nature cotton fibers at different blend ratios. The water absorption capacity, rate, and drying rate of knitted fabrics made from the three composite yams were examined to shed light on their moisture absorption and release performance. Experimental results reveal that the diffusion rate and drying rate become better with decreasing cotton content. However, knitted fabrics made of profiled polyester alone showed the worst water absorption ability, which can be improved with the addition of cotton fiber. For core and cover yarns, the addition of profiled polyester filaments can enhance their performance in moisture absorption and release. In summary, textiles products made from core and cover yams of T-f /T-s/C42/46/12 and 42/35/23 can not only provide a better of touch but also comfort when worn with efficient moisture absorption and release.
