Targeted Sweat Management in Airmen's clothing to prevent hypothermia

Perspiration can be inconvenient, distracting, or even dangerous in certain situations, and most current clothing options do not address this problem. When someone sweats, their clothes eventually become saturated, and the sweat escapes in various ways. This unabsorbed perspiration can cause the wearer to feel wet and cold, it can damage wearable electronics, and it can get into the eyes or on the glasses of the wearer. Current sweat channeling clothing options are limited to disposable and washable plastic channels or expensive fabric t-shirts. This limitation is detrimental, especially to our soldiers, for whom maintaining concentration, equipment, and, most importantly, safety are a top priority.  Soliyarn’s vapor-deposition process is able to selectively coat a continuous piece of fabric with hydrophobic polymers that repel water. By creating uncoated lines/patterns on hydrophobically coated fabric, Soliyarn can create channels that the wearer’s sweat can escape through and be contained within specific and defined areas.
