Fabric Knowledge: Performance Of Moisture Absorption And Sweat Fiber
The moisture absorption and sweat perspiration performance of < p > a href= "http://www.91se91.com/news/" > fiber < /a > depends on its chemical composition and physical structure.
The vaporized moisture evaporated from the skin surface is first absorbed by the fibrous material (i.e. hygroscopic) and then wetted through the surface of the material. The moisture content on the skin surface is caused by the capillary effect generated by the holes in the fiber (pores, pores, grooves) and the gaps between the fibers, causing the moisture to adsorb, diffuse and evaporate (i.e. moisture) at the < a href= "http://www.91se91.com/news/index_c.asp" > material > /a > surface.
The two action results in the migration of water. The former effect is mainly related to the chemical composition of the fiber macromolecules, and the latter is related to the physical structure of the fiber.
< /p >
< p > moisture absorption < a href= "http://www.91se91.com" > sweat fiber < /a > generally has a high specific surface area, there are many holes or grooves on the surface, the cross-section is generally special shaped, capillary effect, so that fiber can quickly absorb moisture and sweat on the skin surface, through diffusion and pmission to the outer layer.

< p > water absorbency of fiber < /p >
< p > moisture absorption and sweat perspiration fiber has the characteristics of water absorption. There are many micro pores or fibrous gaps and surface grooves on the surface of the fibers, making water easy to enter the fibers. Meanwhile, many tubular grooves or capillary tubes along the fiber axis provide a channel for the movement of moisture, so the fibers have good water absorption.
< /p >
< p > drying of fiber < /p >
The moisture content between < p > a href= "http://www.91se91.com" > polyester < /a > is mainly grasped by fibers by a large number of microporous capillary attraction or mechanically maintained in capillary tubes between fibers.
At normal ambient temperature, moisture is easily pported to the surface of the fiber and evaporated.
