Query: Stiff and itchy

I was incredibly disappointed with these sheets after reading the rave reviews. After two washes, they were still very stiff. Additionally, there's something in the sheets that makes me feel very itchy, which has never happened with other sheets. On the plus side, they don't wrinkle, but since they're too itchy to sleep on, the wrinkle-free quality does me no good anyway.
