Dear Rekel I suggest that your bed sheet is acting like a fishing net: a small [but sufficient] entry hole and adequate capacity for many fish. Your underwear has even less intelligence than the common fish and once inside, will tend to stay inside. I seriously doubt whether entropy plays any role in this aspect of the washing process. It can probably be argued that soil removal from the fabric increases overall entropy but whether the gain [via soil removal] or the loss [via entrapment in your bedsheets] is a matter for theologians, not physical chemists.... Thank you for my best laugh of a long day answering 'Why is the sky blue/' questions Ken
