iron the fabric when it is still damp-and use starch or sizing if needed- it's not just whites- most cottons (unless permenent press) need to be ironed after washing- its just the nature of the beast. why are you air drying? generally cottons are washed- regular cycle- tossed into the dryer- take them out before over-drying- especially if you are (pre-shrinking) the dryer heat helps with that.
