The cross section of natural fibers has an irregular shape rather than a circular shape, so that products having unique properties can be obtained. However, chemical fibers, in particular melt-spun fibers, are generally circular in cross section. The closer the cross-section is to the round shape, the softer the touch is, but it is more slippery, and the coverage is poor, and the filament fabric has a lead quality. Poor filling when used for warp knitting.

In order to make up for the shortcomings and to impart new properties, the fiber whose cross section is changed to triangular, pentagonal, hollow, etc. by changing the shape of the spinneret during spinning is called a sectional section yarn.

As such a sectional section yarn, there is a coolmax one, a typical moisture absorption quick-drying functional material developed by DuPont. It is a hygroscopic quick-drying material made of polyester, which has higher absorption and dissipation power than cotton, which is a natural material.

Japanese Teijin's Waveron made four recesses (channels) to pull out the yarns so that they had a larger surface area than ordinary yarns. The four-channel structure causes capillary action, leading to rapid water absorption and discharge. This principle not only ensures a dry and comfortable body at all times, but also has excellent ventilation, good fit and easy care. It is used for various purposes such as professional sportswear and various leisure wears, sports goods such as gloves and hair bands, stockings and socks, underwear such as lingerie.
