Tokyo, Jan 23, 2012 (JCN) - Teijin Fibers Limited, the core company of the Teijin Group's polyester fibers business, has decided to commercialize a new version of its Nanofront high-strength polyester nanofiber with a diameter of 400 nanometers, or 22,500 times smaller than the cross-sectional area of a strand of hair, an unprecedented achievement for a commercial polyester fiber.
The new version, which will be marketed by Teijin Fibers as a finer version of its existing 700-nanometer Nanofront nanofiber, will expand the market for the company's versatile, high-performance nanofiber by meeting demands for even finer nanofibers in applications, such as high-performance air filters that trap especially fine dust particles while allowing increased air flow in compact, energy-efficient air conditioning systems.
Teijin Fibers introduced the world's first commercial polyester nanofiber in 2008. The 700-nanometer version of Nanofront is 7,500 times smaller than the cross section of a hair strand and boasts more than 200 related patent applications.
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, fits body contours comfortably, promotes cooling and boasts excellent absorbency and opaqueness. Nanofront is used in a wide variety of clothing and industrial applications, ranging from inner-wear, golf gloves and skin care products to abrasive cloth and filters.
Teijin Fibers has already established the mass-production technology for even finer nanofiber, as small as 280 nanometers in diameter, which it aims to commercialize eventually.
