A performance yarn composed of a nylon 6,6 embedded with inorganic microparticles that create channels, promoting ventilation and cooling. The yarn itself has a large surface area, which enables the quick transfer of body heat; furthermore, the yarn undergoes a special texturizing process that creates a low-bulk yarn, maximizing the breathability. Fabrics made from this yarn provide cooling with a difference in temperature of 1.1 ˚C (1.98 ˚F). It has a Qmax (a standard to measure the maximum heat loss at the moment of simulation when skin comes in contact with the fabric) value ranging between 0.18 and 0.253 for knitted products and is available in Dtex count — 17/4, 13/4, 44/34/1-2, 78/68/1-2. Applications include intimates, legwear, activewear, and other style- and performance-driven garments.
