ok, gross science peeking it's head in the forum!
cloth gets dirty because of two things: you, and the rest of the world. when you wear clothing, the rest of the world gets on the outside and you get on the inside. by 'you' i'm talking specifically about skin oils and skin flakes. eeewwww!
chances are that the stuff you encounter in the rest of the world typcially isn't oily or greasey, so water temp might not make that much of a difference. think trying to wash greasy dishes in cold water vs hot water: which is more effective? so, if you're washing clothes in cold water, the parts you see (the outside) are likely going to come out fine unless there was grease or oil involved.
now let's apply this to sheets and towels, especially whites. still cloth materials, but unlike your clothes, your sheets and towels are made dirty by you. again with the skin oil and skin flakes.... in this instance, the oils might not be dissolved as easily in cold water as in hot water. with colored sheets you likely wouldn't notice a difference, but with whites, every last thing is going to stand out...
