Outlast Technologies, a market leader for temperature regulating phase change materials (PCMs), has introduced Spherix, a new blend from PCM viscose fibers and polyester fiber balls that is said to offer dynamic climate regulation and added comfort and can be used in apparel.

The new Outlast filling material is soft and breathable, thus offering the advantage of a dynamic heat management, the company reports. The fiber balls are said to provide lightness, volume, and loft, while the PCM viscose fibers account for the temperature management function.

Higher performance

According to Outlast, the company has already successfully gained experience in the bedding market with filling materials while being the pioneer in launching the first PCM polyester fiberfill produced on a large scale. For the apparel market Outlast took a further step and combined fiber balls with a shortcut fiber.

The innovative fiber ball fiber (FBF) blend consists of 30% PCM viscose shortcut fibers and 70% standard polyester balls. “We are working with a highly filled PCM viscose fiber,” explained Martin Bentz, Managing Director of Outlast Europe. “With 7 dtex the diameter of the viscose fiber is quite high, so we can reach an approximately four times higher performance compared to our standard PCM viscose fiber.”

Managing the heat

The new PCM fiberfill regulates the climate proactively – in contrast with other technologies that only wick away humidity, Outlast technology is said to manage the heat while controlling the production of moisture before it begins, so less humidity is produced inside the apparel.

While Outlast technology is often seen as a winter theme, Spherix opens a new addition for summer. Light outdoor wear or even summer quilted jackets will also offer a comfortable temperature regulation with Spherix.

Outlast technology

Outlast technology was originally developed for NASA to protect astronauts from temperature fluctuations in space. It utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort.

The PCMs have the capacity to absorb, store and release excess heat. This gives any product containing Outlast technology the ability to continually regulate skin’s microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.

Outlast technology will proactively manage heat while controlling the production of moisture before it begins.
