Moisture wicking fabric fiber has the characteristics of water absorption, is the surface of the fiber has many internal and external communication of micropores or fibril gaps and surface grooves, making it easy for moisture to enter the fiber. At the same time, many tubular grooves or capillaries along the direction of the fiber axis provide channels for the migration of moisture, so the fiber has good water absorption. After absorbing water, there is no phenomenon of swelling due to water absorption like cotton.
Moisture wicking fabric finishing, as the name suggests is to make the fabric at the same time with water absorption and quick drying.
Absorption of fibers
Moisture wicking fabric fiber has the characteristics of water absorption, is the surface of the fiber has many internal and external communication of micropores or fibril gaps and surface grooves, making it easy for moisture to enter the fiber. At the same time, many tubular grooves or capillaries along the direction of the fiber axis provide channels for the migration of moisture, so the fiber has good water absorption. After absorbing water, there is no phenomenon of swelling due to water absorption like cotton.
Fast-drying properties of fibers The moisture-wicking properties of fibers depend on their chemical composition and physical structure. Gaseous moisture that evaporates from the skin surface is first absorbed by the fibrous material, which we call the moisture absorption process. After that, the surface of the fiber material is wet, and the liquid moisture on the surface of the skin is absorbed, diffused and evaporated on the surface of the fiber material by the capillary effect generated by the capillaries, micropores, grooves and gaps between the fibers. The results of the two processes lead to the occurrence of water migration, the former effect is mainly related to the chemical composition of the fiber macromolecules, and the latter effect is related to the physical structure of the fiber.
The moisture between the polyester fibers is mainly held by the fibers by a large number of microporous capillary gravity, or mechanically held in the capillary between the fibers, and the moisture is easily transported to the fiber surface and volatilized at normal ambient temperature.
Moisture wicking fabric fiber generally has a high specific surface area, the surface has many micropores or grooves, its cross section is generally a special shape, the use of capillary effect, so that the fiber can quickly absorb moisture and sweat on the surface of the skin, through diffusion, transfer to the outer layer of evaporation.
