Magazine for Textiles, Clothing, Leather and Technology » CELLIANT Viscose Converts Body Heat to Infrared Energy »

 Mey GmbH & Co. KG, the global manufacturer of underwear, nightwear, and lingerie based in Germany, is launching the world’s first nightwear worldwide with CELLIANT® viscose, which converts body heat into energy. CELLIANT viscose is a unique combination of nature and performance. It was developed by materials science leader Hologenix®, creators of CELLIANT, a responsive textile using infrared technology, and Kelheim Fibres, the leading manufacturer of viscose specialty fibers.

The collection consists of five designs in two colors, Natural and Deep Taupe, and is called “mey Zzzleepwear – THE NEW SLEEP-LIFE BALANCE.” It is the world’s first nightwear that converts body heat to energy with CELLIANT viscose. CELLIANT converts the heat emitted by the body into full-spectrum infrared energy and reflects it back to the skin. This supports local circulation and helps improve cellular oxygenation.

CELLIANT viscose features natural, ethically sourced minerals embedded into plant-based fibers and is biodegradable. CELLIANT viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as the fiber enhancements from CELLIANT infrared technology. In addition, CELLIANT is durable and will not wash out, lasting the useful life of the product it powers. 

Sustainability isn’t just a trend for us, it is part of our tradition,” said Matthias Mey, Managing Partner of mey. “The first-ever nightwear with CELLIANT viscose is a testament to our continued commitment to sustainability. Sleep is the most rejuvenating time of the day and with the added infrared properties of CELLIANT technology combined with the soft, lightweight viscose fiber, our product should make it even more restful and restorative.”

A True Partnership

The bridge between the unique CELLIANT technology and the renowned manufacturer mey was formed by the Bavarian viscose specialty fiber manufacturer Kelheim Fibres. Kelheim Fibres’s
flexible production technology allows targeted interventions in the viscose fiber process; CELLIANT minerals can thus be introduced directly into the spinning mass and lead to a permanent and durable functionalization of the fiber. The skin-friendly surface structure of viscose and its other advantages, such as its softness or excellent moisture management, are retained. CELLIANT viscose is the world’s first in-fiber sustainable infrared viscose. 

Dr. Marina Crnoja-Cosic, Director New Business at Kelheim Fibres, said, “We congratulate mey on the launch of the new sleepwear collection. Accelerating the commercialization from the fiber development to the end product as possible through the close interaction of all participants in the value chain. We are pleased that mey offers the consumer garments with innovative and future-oriented technology combined with proven quality for increased well-being and better sleep.”

“The development of this first-ever CELLIANT viscose nightwear is indicative of the true partnership between us, Kelheim and mey, bringing together fiber innovation from two companies into a commercially available fabric and product from mey, the esteemed bodywear manufacturer,” concluded Seth Casden, Hologenix co-founder and CEO. “We hope to positively impact the lives of those using our products.”
