Tearfil has just launched two new fibres that stand out for their innovation, but also because they take sustainability concerns to the next level. And while one of them originates from hemp, a plant with a tradition in the textile area, the second has its origins in spatial research.

In fact, the Outlast technology was originally developed for NASA, in order to protect astronauts against extreme temperature changes in space. The innovation uses microencapsulated phase change materials (MPCM) that absorb heat, store it and release it for optimal thermal comfort, explains Tearfil. The product – in Portugal sold exclusively to Tearfil – has, therefore, the ability to continuously regulate the skin’s microclimate.

Over the years, the Outlast technology has been developed to meet the consumer market and everyday needs. The microcapsules that contain the phase change material are integrated into the textile fibres that make the garments. Fabrics made from these fibres do not compromise weight or softness when compared to other materials.

On the other hand, hemp fibres are indicated for textile uses, and are obtained through the processing of the fibrous external part of the plant’s stem. Hemp is a fast growing plant that enriches the soil, interrupts disease and pest cycles, and suppresses weeds for subsequent crops. It’s rain fed and requires very few chemicals, so it is proven as an ecological product.
