Teijin's Nanofront Polyester Nanofiber Used in New Balance Socks
(Nanowerk News) Teijin Fibers Limited, the core company of the Teijin Group's polyester fibers business, announced today that it is supplying its high-strength polyester nanofiber Nanofront for use in running socks made by New Balance. The socks are being marketed by New Balance Japan and sold in its directly owned shops in Tokyo and Osaka, as well as other sports retail stores nationwide from this month.
Nanofront is used in most of the sock, except the toe, heel and cuff. Frictional force, one of the noteworthy properties of Nanofront, creates outstanding slip resistance to help prevent the sock from sliding inside a shoe, thereby reducing blisters and shoe sores. Nanofront also boasts high absorbency for added comfort.
Nanofront is a high-strength polyester fiber with a thickness of just 700 nanometers, or 7,500 times thinner than a strand of hair. Teijin's proprietary "island-in-sea" composite spinning technology eliminates the problem of unstable quality associated with conventional mass-produced nanofibers. Nano-sized bumps on the surface of Nanofront raise frictional force and produce a surface area dozens of times greater than that of regular fiber, giving the material outstanding slip resistance. The ultra-fine fiber is also soft, stretchable and boasts excellent absorbency and opaqueness.
Nanofront is also used in shoelaces made by New Balance Japan.
Teijin Fibers started commercial production of Nanofront in 2008 and has been developing applications in areas such as innerwear, sportswear and industrial materials.
