Question on self-wicking polypropylene fabric
I will be sewing self-wicking polypropylene fabric for sports underwear. The fabric has a very smooth side and a somewhat meshy side. I want to know which side to use next to the body. It is critical that any sweating has to wick AWAY from the body.
I have tested (with sprinkles of water) on both sides to see which wicks away the moisture fastest but there wasn’t a lot of difference. I suspect the meshy side should be next to the body but want to be absolutely sure.
