Lint issue with my microfibres

Hi there, I’ve been having issues with my drying microfibres towels. They keep giving off lint while I’m drying my cars. They are dedicated drying towels and I don’t use them for anything else. I wash them between every use with a detergent designed for microfiber towels and try to keep them away from other towels. Can anyone recommend any remedies.

Edit: I use Meguars and Mothers 70*40cm towels
