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.
