Tokyo, Japan, October 26, 2016 --- Teijin Frontier Co., Ltd., the Teijin Group’s fiber products converting company, announced today that it has developed Solotex RC, a polytrimethylene terephthalate (PTT) fiber with a bulky three-dimensional structure for lightweight and cushiony high-function fabrics.

  • -Warm and gentle elasticity thanks to a molecular structure
  • -Omnidirectional bulkiness due to a three-dimensional structure
  • -Easy to care as a synthetic
  • -Highly comfortable wear due to strechability

 SOLOTEX®RC, a new bulky PTT fiber


Bulky More than 2x that of normal processed fiber
Cushiony More than 6x that of normal processed fiber
Shape-retaining More than 6x that of normal processed fiber

Teijin Frontier previously developed SOLOTEX, a soft, shape-retaining, stretchable PTT fiber that offers bright coloring, eco-friendliness and compatibility with a wide range of other materials. SOLOTEX staple fiber wadding offers excellent cushioning but does not retain its shape. The newly developed Solotex RC, however, provides superior vertical cushioning thanks to the use of crimped PTT fiber arranged in a continuous radial around a main axis. Teijin Frontier’s unique three-dimensional fiber also offers significant freedom in designing. Teijin Frontier will conduct trial sales mainly for sport apparel in the current fiscal year. Annual sales are expected to reach 30 tons by the fiscal year ending in March 2019.
