The fabric is annoying due to the sticky feeling caused by sweat at high temperature in summer, and consumers hope to have a comfortable and healthy garment for improving damp-heat state in summer or under the condition that a large amount of sweat appears in sports.
The moisture absorption and perspiration functions can maximally transport moisture or vapor from the inner layer to the outer layer of the fabric so as to ensure the refreshing and drying of the skin surface. The diameter of the water vapor molecule is 0.0004 micron, and the water vapor can smoothly pass through, and the diameter of the rain mist is as follows: the fog is 20 microns, the light fog is 200 microns, and the diameters of various water drops and rain drops are all larger than 500 microns. In order to ensure that water vapor and rain mist can be discharged to the outer layer of the fabric through the tortuous micropore channels, a certain vapor pressure difference or a certain temperature gradient exists between the inner layer and the outer layer of the fabric.
