Sweat-absorbent and quick-drying processing

Sweat-absorbent and quick-drying processing is a processing method that imparts sweat-absorbing properties and quickly moves and spreads it to the outside. Processing methods that impart sweat absorption include microporous polyester fiber and hydrophilic polymer coating method, core-sheath composite spinning method, etc.

There is a processing method to move sweat quickly. A polymer that imparts water absorbency to polyester fiber aggregates with cross-sectional shapes such as processing method.

Recently, through research on woven and knitted structures, technology has been successfully realized to move sweat from the skin side to the outside of clothing and dissipate it. This technology is being used in sportswear applications. That is to say, the skin side is a dense tissue of hygroscopic and water-absorbent cotton fibers, and the middle layer is a denser synthetic fiber that moves sweat to the surface layer and separates the skin side from the outer air layer. The purpose of the layer is to quickly discharge the absorbed sweat to the outside, using a tissue with a larger and denser surface area than the skin side. Materials such as “ALSACE” (Toyobo) and “AQUADRY” (Teijin) produced based on this idea have been commercialized as “sweat-absorbent and quick-drying” underwear materials. These are the main materials for cool business purposes.
