Fiber helps to keep cool

AquaBreath is the name of a modified polyamide (PA) fiber that can actively respond to the moisture of skin microclimate. Mixed with polymers, AquaBreath is intrinsically equipped with high hydrophilicity and moisture exhaustion function to quickly absorb and evaporate sweat. Moreover, the fiber can sense human microclimate at any time and activates its deformation mechanism to provide good comfort for wearers. 

The fabric demonstrates visual changes with the structure design and creates deformation called air chambers. When the wearer exercises and sweats, the fabric absorbs the sweat from the human skin surface and elongates to form air chambers, which helps increase convection. The stickiness can quickly be reduced because of the high air permeability, generating a cool feeling. After exercising, the fiber shrinks to reduce the air permeability, and the air chamber, in turn, keeps the warm air, providing a warming effect and preventing chills after exercise. 

With the combination of the fiber property of high hydrophilicity, moisture exhaustion, and deformation, AquaBreath delivers quick-drying and high air permeability effects, providing coolness and comfort. AquaBreath was developed by the Taiwan Textile Research Institute (TTRI), Taipei/Taiwan, and is supported by the Department of Industrial Technology, Ministry of Economic Affairs, Taiwan. It comprises 100% single modified PA. Unlike other products using PET and other materials in the market to achieve the stretching and deformation effect, AquaBreath uses single material, which is conducive to the next step of recycling after consumption. For the end-of-life of product recycling process, the product of AquaBreath can save a lot of processing time, without the need to separate the blended textiles. The fiber can be easily recycled, and it is in line with the trend of zero carbon emission and a circular economy.
