Moisture Absorption and Release of Profiled Polyester and Cotton Composite Knitted Fabrics

Composite yarns were spun using profiled polyester fibers and nature cotton fibers at different blend ratios. The water absorption capacity, diffusion rate, and drying rate of knitted fabrics made from the three composite yarns 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 yarns of T f /T s /C 42/46/12 and 42/35/23 can not only provide a better sense of touch but also comfort when worn with efficient moisture absorption and release.
