what i learned from AI , HOW WETTING WOOL GENERATES HEAT
how does lightly dampened wool generate heat When wool absorbs moisture, it generates heat through a natural exothermic chemical process called heat of sorption (or absorption) . Here is exactly how it works: Chemical bonding: Wool fibers are made of a resilient protein called keratin . This protein structure contains millions of hydrophilic (water-loving) chemical sites. Breaking and making bonds: When wool gets lightly dampened, water vapor molecules enter the fiber and collide with these chemical sites. The water molecules form hydrogen bonds with the amino acids in the keratin. Energy release: As these new chemical bonds are created, kinetic energy is released in the form of heat . Because wool can absorb up to 33% of its dry weight in moisture without feeling wet to the touch, this process can generate a surprising amount of warmth. For example, when a dry wool garment absorbs moisture from body sweat or a damp environment, it can release enough heat to feel noticeably ...
