Capillary pressure and liquid wicking in three-dimensional nonwoven materials

In this paper, Mao proposed a novel model of directional capillary pressure and wicking for three-dimensional nonwoven fabrics based on both the concept of equivalent hydraulic pressure and Darcy's law. This is the only model available to predict the capillary wicking in fibrous materials based on fabric structural parameters. It has been validated and adopted in studies by other researchers in the world.

This model is the only model available for engineering design of three-dimensional technical textile products in relation to wicking before the fabric is made. Prior to the establishment of this model, any wicking performance of a fabric is only known by means of experimental measurement after the fabric is physical made. It is therefore adopted internationally in design of healthcare, wound dressing, filter and functional clothing.
