In recent years, people fabric comfort, functionality requirements are high, but as people increase in outdoor activities, casual wear and sportswear trend of mutual penetration and integration are increasingly popular with consumers favor. Such clothing fabrics, both require good comfort, and enjoy activities requested at the time, once the sweat, the clothing will not stick skin to produce cold and wet, heavy feeling. So the proposed new requirements for fabric wicking capabilities.

However, for the fabric moisture and perspiration, the average consumer will be confused. In fact, this is the two concepts, namely fabric moisture absorption and humidity.

First, we talk about the absorbent. In polyester fibers, for example, actually small water absorption, poor moisture permeability, in the sweltering prone activity; natural fibers of cotton, for example, its moisture absorption, and wear comfortable, but slightly larger when people sweat cotton fibers swell due to moisture absorption, and affixed to the skin, while moisture divergence has been slower, giving the human body, a cold wet feeling.

So, for all fabrics, especially polyester products, in finishing stage with a hydrophilic additives deal is a good way to improve hygroscopic.

But this end? Resolved absorbent can make the wearer stay dry it? Moisture = perspiration?

Of course not! Only adsorbed moisture fabric surface fabric discharged as much as possible, in the sun exposure and good ventilation adequate moisture evaporates, which can keep the wearer dry and comfortable.

The fabric of humidity depends on the physical structure and morphology of the fiber. Gaseous evaporation from the skin surface moisture is first absorbed by the fabric (ie moisture, ---- Note the fabric absorbent, but not fiber!) And then between the fibers within the holes (pores, pores, trenches) and fiber capillary effect resulting voids between the fabrics moisture adsorption, diffusion. Thus, the fabric surface moisture migration occurs and evaporated, thus completing the process of humidity.

Therefore, only the moisture is not enough. For some common synthetic fabrics, just carry on with a hydrophilic additives after finishing, then flaunt moisture "wicking" actually put us all into a misunderstanding.

In synthetic fiber production, changing the shape of the nozzle hole in the longitudinal direction of the fibers to produce a plurality of grooves, can enhance the specific surface area of the fibers. This improves the fiber moisture conductivity, by wicking action to achieve these trenches perspiration. Such as the production of INVISTA polyester for wicking COOLMAX® fabric authentication. Its unique flat cross-section of the fiber surface into four longitudinal grooves. Its 20% larger than the surface area than conventional round, so wicking performance than conventional polyester. In particular, note that: clothing fibers because of processing, cross-section has been greatly undermined (resulting in a plastic deformation), thus reducing the effects of perspiration, and INVISTA's new "CCOO" type polyester may be larger relieve extent this plastic deformation, which can maximize the wicking capabilities ----- C type guide groove deformation. In addition, for consumers, the function of the yarn is important, but the real functionality to ensure clothing More importantly, fabric quality and functionality.
