In what it claims to be a world-first, Teijin Frontier of Osaka, Japan, has developed polymer-control and spinning technologies that enable the mass-production of nanofibres from recycled polyester (PES).The company adds that the technologies will enable it to use recycled feedstocks for all of its PES-based fibre products.The nanofibres, part of its Nanofront range"(1), display the same properties as those produced from virgin feedstocks. Nano-sized bumps on the surface of Nanofront increase the fibre's frictional force and give it high slip-resistance, as well as contributing to a surface area that is many times greater than that of conventional fibre. The ultra-fine fibre is also strong, yet soft and stretchable (fitting to body contours comfortably), and when used in fabrics promotes cooling, excellent absorbency of moisture and opacity. Consequently, manufacturers use Nanofront in a variety of clothing and industrial applications, ranging from inner-wear, socks, golf gloves and skin-care products to abrasive cloths and filters.
