Advice on laundry/dryer kleenex?

A few months ago my husband accidentally washed and dried a piece of clothing that had a kleenex in it, and we still get bits of white kleenex everywhere after laundry. It looks like tiny bits of lint, but it's actually kleenex. I don't know what to do or how to fix it, it's been months and it's still coming out like this. Any advice?
