New “Octopus” polyester fiber from Teijin Fibers Ltd.

December 2nd, 2011 / By: / Products

Teijin Fibers Ltd., the core company of the Teijin Group’s polyester fibers business, has developed an unprecedented polyester fiber with a unique, highly modified cross-section with eight projections aligned in a radial pattern around a hollow fiber. The new fiber, named Octa after its octopus-like appearance, offers rapid sweat absorption and drying, low weight, heat shielding/insulation and useful bulkiness. Octa will be marketed from April 2012 for innerwear, fashion apparel and many other uses.

The voids between the eight projections result in a highly functional fiber for sweat absorption, rapid drying and bulkiness. The voids also improve heat shielding and insulation properties, as well as create the lightweight feel of hollow yarn at roughly half the weight of yarn of similar thickness. Octa can also be used in combination with other fibers through false twisting, combined filament processing and two-strand yarn spinning.
