The hygroscopicity principle of knitted fabrics

The principle of hygroscopicity of knitted fabrics mainly involves the chemical composition and physical structure of fibers. Knitted fabrics usually use hygroscopic fiber materials, such as natural fibers such as cotton, wool, and silk, as well as specially treated synthetic fibers such as polyester. These fiber surfaces have many micropores or grooves, which can quickly absorb moisture and sweat from the skin surface through the capillary effect.

In addition, the weaving structure of knitted fabrics also has an important influence on their hygroscopicity. Knitted structures usually have a large porosity, which helps the migration and diffusion of moisture. Moisture can be quickly transferred to the outer layer of the fabric through the capillary action between fibers and evaporated under suitable conditions, thereby achieving a quick drying effect.

In the post-finishing process, knitted fabrics can also further improve their hygroscopicity by adding hygroscopic and perspiration-releasing agents. These finishing agents can form hydrophilic compounds on the fiber surface, enhancing the water absorption capacity and wetting properties of the fiber. At the same time, they can also improve the antistatic and stain-removal properties of the fabric, making it have better wearing performance.

In general, the hygroscopicity of knitted fabrics mainly includes the hygroscopic properties of fiber materials, the capillary effect of the woven structure, and the application of hygroscopic and perspiration-absorbing agents during the finishing process. These factors work together to enable knitted fabrics to quickly absorb and discharge moisture, providing a comfortable wearing experience.
