puzzled

All I asked was one thing, and of my many friends, none could come up with a suitable answer, or even really a suggestion, as to what exactly would Permanent Press be appropriate for. According to Chris, it was the setting on the dryer that got "really really hot" so he used it for towels and sheets, things he didn't care about shrinking (what if you shrank sheets down to like, twin sized from full sized??). Others fielded answers as varied as "its for delicates" and "it is only for clothes you WEAR, everything else goes in regular." How can it be that a cycle exsists on the Dryer, has been there since who knows when, and yet, not one of the people I know understands what the hell it really does? Searching on google determined that Permenant Press was:

"A permanent press is a fabric that has been chemically processed with methanol to resist wrinkles and hold its shape. Treating fabric with the simplest form of alcohol (methanol) has a lasting effect on the fabric."

And so, we learn that alcohol is involved, perhaps guiding us closer to the root cause of this apparently useless laundry cycle. How is it that I know if my clothes have been treated with methanol? Why would I want that? Is this like the Dockers stain defenders pants? Because seriously, if they are stain defensive, why is it that they need a special cycle at all? And why would anyone want to dry something with alcohol on it at an even higher temperature (if chris's hypothesis was correct) than good old 100% Algodon? I really want some answers here people, because this is not acceptable. Meanwhile, I am making sure that I never, ever put anything on this cycle; who knows what might come out?
