I am also allergic to fabric. I wash mine only once and this does the trick. I make sure my fabric is completely unfolded before I put it in the washing machine and make sure you get all the knots and wrap arounds lose before you dry it. I take mine out a little damp,then iron. I wash up to 4 yards at a time,anything else and I get wrinkles also. This may take awhile to do but it is well worth it.
