Outlast launches new PCM acrylic fiber

A new production process has allowed the Outlast® acrylic fiber to perform four times better than the existing version. “We are using now a non-encapsulated pPCM system and we no longer work with encapsulated mPCMs here,” says Martin Bentz, President of Outlast Technologies LLC, Golden/USA.“This change allowed us to improve the performance of the new Outlast® acrylic fibers enormously. With that, the spinning and dyeing properties are enhanced."
This especially plays a positive role for dark colors - darker tones are easier to achieve now through a better color absorbance.
The new Outlast® acrylic fiber blends very well with wool. It is well suited for use in socks, knitwear (e.g. pullovers) and home textiles (blankets) offering the significant added value of a dynamic heat and moisture management. The new Outlast® acrylic fibers absorb excess body heat, store and release it.

The performance fibers regulate the climate proactively – in contrast with other technologies that only wick away humidity. Outlast® technology proactively manages heat while controlling the production of moisture before it begins, so less humidity is produced inside the apparel. This Outlast® difference also results in more comfort as well as improved hygiene, which is important especially when it comes to socks.
Outlast® technology
Outlast® technology was originally developed for NASA to protect astronauts from temperature fluctuations in space. Outlast® technology utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort. Outlast® technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for a longer period of time. Outlast® phase change materials work in the same way.
The PCMs have the capacity to absorb, store and release excess heat. This gives any product containing Outlast® technology the ability to continually regulate the skin’s microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.
Outlast® technology is not wicking technology, which manages moisture by reacting to your sweat and pulling it away from the skin. Outlast® technology will proactively manage heat while controlling the production of moisture before it begins. That’s the Outlast® difference. The benefits of Outlast® products at a glance:
- Absorbs excess body heat
- Manages moisture
- Reduces overheating
- Reduces chilling
- Reduces perspiration
- Continuously adapts to thermal changes
