Why can iron and dryer both make clothes with less wrinkles? Is there some physical or chemical process that smooths out the clothes?
Which factor in a dryer that smooths out the clothes, rotation, heat, or something else?
which factor in an iron that smooths out the clothes, press, heat, vapor or some water, or something else?
Is it because of some common factor (e.g. heat) that makes a dryer and an iron smooth out clothes? Or is it because of some factor that belongs to a dryer but not to an iron, or to an iron but not to a dryer?
