Introducing Celliant Viscose. Nature-based Fibers. Infrared Wellness.

We’re thrilled to announce the launch of CELLIANT Viscose — the first in-fiber viscose infrared solution. This sustainable textile innovation is in collaboration with Kelheim Fibres, the world’s leading manufacturer of specialty viscose.

CELLIANT Viscose is an extremely versatile fiber that blends beautifully with cotton, micromodal, lyocell, wool varieties (including cashmere), and other fibers. It has numerous applications across industries and is ideally suited for performance wear, luxury loungewear, casual wear, bedding and more.

CELLIANT Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as fiber enhancements from CELLIANT infrared technology. CELLIANT inhibits odor and helps to regulate body temperature. In addition, CELLIANT is durable and will not wash out, lasting the useful life of the product it powers.

Kelheim Fibres, the world leading manufacturer of specialty viscose, joins Hologenix, inventors of CELLIANT, to create a sustainable, nature-based intrinsically functionalized CELLIANT Viscose fiber. CELLIANT Viscose is certified by FSC® or PEFC™, which guarantees the origin in sustainably managed plantations. In addition, Kelheim Fibres was awarded a green shirt in Canopy’s 2020 Hot Button Ranking. This indicates a leadership role in raw material sourcing.

Kelheim’s winning formula is their flexible technology that allows targeted interventions in the viscose fiber process. By modifying the fiber’s dimensions or cross sections or by incorporating additives into the fiber matrix, Kelheim can precisely define the fiber’s properties according to the specific needs of the end product. The production of CELLIANT Viscose takes place exclusively in Germany, complying with Germany’s strict environmental laws, guaranteeing an overall eco-friendly product.

The combination of Kelheim’s distinctive technology and the functional CELLIANT additives creates a unique fiber that provides full functionality without the need for any additional processing step – a new standard in the field of sustainable IR viscose fibers.

CELLIANT Viscose officially debuted at ISPO Textrends Munich 2021, where it was chosen as a Finalist in the Fibers and Insulations category for the ISPO Awards 2021.
