The "minkee" that I've tried works as an inner, it seems to be slightly absorbent even though it's synthetic. I think it uses "microfibers" and because of the fluffiness traps a little moisture. I've only seen it used as an outer with hidden PUL. It would make really soft (and expensive) wipes, and it has enough texture to it that I think it would work (especially if backed with something cotton).
