Breathability of Closed-Cell Y-Warm




Y-Warm, featuring its own hydrophilic groups, has a water absorption rate 280% that of the standard test sample and a drying rate 2.5 times faster.

Applied in apparels, Y-Warm provides powerful moisture absorption: the inner layer draws sweat away from the body, while the outer layer facilitates rapid evaporation for enhanced breathability and a quick-dry effect.

According to third-party tests for moisture absorption, Y-Warm has a moisture permeability rate of approximately 3800 g/(m²·24h). However, its actual comfort in wear exceeds that of fabrics with a rate of 20,000 g/(m²·24h). Why is there such a discrepancy?

Answer: Y-Warm can absorb several times its own weight in moisture. The standard test measures vapor transfer over just one hour. However, due to its closed-cell structure and 700-micrometer thickness, Y-Warm is still absorbing moisture during the test hour, which delays transfer to the evaporative side. Therefore, the one-hour test is insufficient for an objective evaluation of its true performance.
