The rise of moisture-wicking products can be traced back to the 1970s. Usually, the human body will notice the discharge of large amounts of sweat only when engaging in strenuous exercise. In fact, even under normal environmental conditions, the human body needs constant “insensitive evaporation” to release the heat and water vapor generated by the body’s own metabolism in order to maintain a constant body temperature. Therefore, how to use textile clothing that is in close contact with the skin to transfer heat and water vapor from the body surface to the outside world. Through a series of processes of “moisture absorption → conduction → evaporation”, it not only constitutes the core of the moisture absorption and perspiration function of textile clothing, but also the current The basis for the development of testing methods for the moisture wicking function of all textile products.
Natural fibers generally have good moisture absorption and perspiration functions due to their specific supramolecular structure and surface morphology. However, for most synthetic fibers, due to their inherent hydrophobic properties and smooth surface morphology, it is difficult to bear the moisture absorption and perspiration required by the human body. Sweat function. If you want to give textiles made of this type of fiber material moisture-absorbing and sweat-wicking properties, you can start in the following directions:
One is to start with the chemical structure modification of fiber raw materials to improve its hygroscopicity;
The second is to modify the physical form and structure of fiber materials to improve their moisture absorption and moisture conduction properties with the help of capillary effect, such as the application of fiber differentiation technologies such as hollow, grooves, different cross-sections, surface micropores, and fine denier. ;
The third is to achieve the effect of increasing moisture absorption and perspiration through reasonable fabric structure design;
The fourth is to use appropriate post-finishing technology (including coating finishing processing) to give the fabric good moisture absorption and perspiration functions.
