SOLOTEX®

Solotex® is a synthetic fiber made of poly trimethylene terephthalate, a polycondensate of 1,3-propanediol and terephthalic acid. Solotex® displays outstanding dye ability and compatibility with a variety of other fibers in blends. Deep, rich colors can be obtained with dyeing at 98 to 120°C. Apparel made with Solotex®resist wrinkling and retains its shape without deformation, even with repeated bending at the knees and elbows. The zigzag structure of Solotexä allows the fibers to stretch at low tension, with a high recovery rate, enabling comfortable stretch/recovery in a wide range of applications. Solotex® is available in staple fiber, regular and conjugate multi-filament yarn, and monofilament yarn.
