RadiciSpandex, Fall River, Mass., has developed Type S 45, a multi-purpose elastane fiber
engineered specifically to resist the damaging effects of high-temperature dyeing.It is now
possible to dye blends of polyester and spandex to deep, dark shades without disintegrating the
elastane at the elevated temperatures needed to dye polyester.RadiciSpandex collaborated on the
project with the fabric converter Cyberknit. The New York City-based company said Type S 45 has
surpassed its expectations, allowing the firm to offer its customers the rich colors they have been
seeking in polyester microfiber/spandex blended fabrics.
