Teijin Frontier Develops New Functional FabricFeaturing Unique Span-like Texture and High Stretchability
Tokyo, Japan, June 8, 2023 --- Teijin Frontier Co., Ltd., the Teijin Group’s fibers andproducts converting company, today announced the development of SOLOTEX®
LIBERTE, a new functional fabric for sportswear and casual wear. SOLOTEX® LIBERTE
fabric features a unique span-like texture and exceptional stretchability, as well asexcellent colorability, luster and natural swelling. This innovative fabric combines comfort
with sustainability, thanks to its incorporation of plant-derived raw materials.

SOLOTEX® LIBERTESOLOTEX® LIBERTE uses polytrimethylene terephthalate (PTT) fiber featuring aproprietary low-shrinkage technology and a distinctive yarn processing method thatmaximizes the properties of PTT while controlling the raw yarn’s heat shrinkability.
Specifically, this product uses side-by-side composite yarn (*), which Teijin Frontier
cultivated with its variety of SOLOTEX® stretch fabrics, that combines PTT polymer as thecore yarn with newly developed low-orientation, low-shrinkage PTT monocomponent as
the sheath yarn. The result is a blended yarn with two different shrinkage properties. Afterthe core and sheath yarns are randomly mixed using fiber processing technology, they
are knitted using high-density knitting equipment.
*Side-by-side composite yarn achieves high stretchability by laminating two types of polymers withdifferent heat shrinkability characteristics to form a coil-like crimp structure.

SOLOTEX® LIBERTE fabric features a soft texture and smooth finish. It also provides
beautiful aesthetics, including vivid colors and a luxurious matte glossy appearance. The
material has a high silhouette with a moderate drape. Apparel made with SOLOTEX®
LIBERTE provides comfort, thanks to its soft stretch, light weight, water absorption andquick drying properties.

In addition to superior texture and appearance, consumers are demanding exceptionalcomfort and lower environmental impact. Teijin Frontier’s SOLOTEX® fiber delivers soft,
smooth fabric with an attractive appearance, and supports sustainability by usingapproximately 40 percent plant-derived raw material.
SOLOTEX® has variety of lineups such as stretch fabrics using side-by-side composite
yarn and soft and smooth fabric with colorability using PTT monocomponent taking
advantage of PTT fiber’s characteristics. Teijin Frontier has been widely promoting
SOLOTEX® in the global market and also developing fabrics that make the most of its
characteristics, however, it could not achieve excellent stretchability and sufficient swellingat the same time due to the difficulty in controlling the heat shrinkage of PTT polymer.
Teijin Frontier will begin promoting SOLOTEX® LIBERTE globally for the autumn andwinter 2024 collections of sportswear and casual wear. The company expects sales ofSOLOTEX® LIBERTE to reach 500,000m by fiscal 2026.
