What is this?

I air dry most of my Jiu jitsu clothes and I’ve noticed this odd substance on them. It’s almost like a lint like substance that’s hardened. It’s tricky to get off too. It’s never on my clothes that go in the dryer, but always on the clothes in the garment bag that gets air dried.
Is there a way to avoid this?
