Figure: Seven defining characteristics of SOLOTEX®®

Figure: Molecular Structure/ SOLOTEX® conceptual image

These are the seven defining characteristics of SOLOTEX® that derive from the unique molecular structure of the fiber. The molecules from a flexible spring-like helix that makes the fiber soft, light, stretchy, and shape-stable.SOLOTEX® can be used for clothing or in a wide range of materials, offering limitless possibilities because of its structure.

Super soft feel and smoothness for comfort
Icon: Soft & SmoothSoft & Smooth

The moment you touch it, you understand the softness of SOLOTEX®. It feels even softer than luxury cashmere wool. Smooth against the skin, it is more comfortable to wear than any fiber that has come before. Blending with other fibers does not affect its superb softness, while maintaining the beneficial qualities of blended fibers.

Keeps its shape to look great
Icon: Form StabilityForm Stability

A spring-like, helical molecular structure provides from stability to "spring" back into shape even with movement. The fiber resists wrinkles and does not easily get stretched out from repeated bending at the knee or elbow, maintaining a beautiful shape at all times. There is also little shrinkage or stretch even after repeated machine washings and tumble drying, demonstrating superb dimensional stability.

Stretchiness that feels great, with no stress
Icon: Comfortable StretchComfortable Stretch

SOLOTEX® is surprisingly free of any feeling of pressure, even following the lines of the body.
It expands and contracts in any direction with the body's movement, feeling truly comfortable and allowing for free movement. SOLOTEX® is ideal for tight-fitting bottom wear and active clothing.

SOLOTEX® is easy to combine with other fibers. It is highly compatible with both synthetic and natural fibers, for blending as desired. The fiber will add a soft texture to improve the feel against the skin, and it provides superb stretch and recovery from elongation. It is possible to add new texture and new functionality while bringing out the characteristics of the blended fiber.

Plant-based eco-friendly ingredients
Icon: EcologyEcology

Biomass-derived, plant-based ingredients are used for 37% of the polymers that make up SOLOTEX®. The fabric thus reduces consumption of fosil fuels, and helps cut down on greenhouse gases. SOLOTEX® is an eco-friendly fiber that is kind to people and on the environment.
