The directional water diversion means that water can not flow reversely in a single direction in a substance with a specific structure. This phenomenon is ubiquitous in nature and in the human body, such as blood transport in arteriovenous vessels, water flow direction in rivers, liquid exchange of biological membranes, absorption of moisture by plants from soil, and the like. As an important branch of the directional water guide material, the directional water guide fabric is usually finished by hydrophilic and hydrophobic fibers or hydrophilic and hydrophobic finishing to make one surface of the fabric hydrophilic and the other surface hydrophobic, a moisture guide gradient is formed in the thickness direction, a differential capillary effect is generated, and a directional water guide function is realized. The hydrophobic surface of the directional water guide fabric is in contact with a human body, when the human body discharges liquid, the liquid can be rapidly transferred from the hydrophobic layer to the hydrophilic layer, and the hydrophilic layer absorbs the liquid in time and does not return to seep, so that a comfortable wearing microenvironment is provided for the human body, and the directional water guide fabric is suitable for being used as sports clothes, underwear, paper diapers, sanitary napkins, protective pads, surgical gowns and the like.
