Hey everyone. I'm having some problems with a year 11 chemistry assignment, which is about the effectiveness of different fibers in thermal clothing. I am discussing wool and polypropylene thermal clothing, and my teacher would like me to explain how the materials "wick" away moisture. "Wicking" is where the material draws moisture away from the body and allows it to be evaporated in the air. The difficulty is how, since both wool and polypropylene have hydrophobic characteristics, meaning they repel water, so I'm not sure how it absorbs it. Any help would be greatly appreciated, and links to any useful sites would be a huge help.
Thanks!
