Question from Mir

I was looking at a simple sweatshirt that says it has ‘Moisture-wicking technology’.  Does this always refer to a chemical treatment of some kind?

There is no specific standard for the term “moisture wicking” so it could vary.  Wool can be considering a natural moisture-wicking material.  Synthetic fibers such as polyester do not retain moisture like natural fibers do so they push excess moisture through the weave and away from your body. Even without a chemical treatment they could be considered “moisture-wicking”.   Some fabrics do have a chemical treatment on the fabric to improve the performance.
