Abstract: Having expounded the moisture transmitting ways of the fabric,the article analyzed the properties of moisture absorption and wet wicking and the mechanism of moisture transmittance of the fabric,and deduced the formula of the total flow of capillary water transport.The cross section of pentalobal polyester fiber_coolfibre and its wicking ability were introduced and regression equation between the wicking time and the wicking height was derived.The fabric material and its geometric structure from the fabric inside to outside for rapid wicking perspiration were suggested.In this study,Coolfibre polyester filament was used as warp to form a warp-faced fabric so as to keep a dry microclimate between skin and fabric.For the purpose of providing useful reference for the development of dry fabrics,five kinds of fabric have been designed and analyzed with respect to the strength and extension,air permeability,moisture absorption,wicking height,moisturizing capacity,and drying.
