might i suggest washing it , yes wshing it, add detergent, and lots of fabric softner, do it on a hot setting, maybe even do it twice, then spin dry, and hang it out side, it should look considerably more textured than it started, (i would do a test peice, just to be sure it gives you your results)
DO NOT PUT IT IN THE DRYER < IT WILL DESTROY THE PILE
AIR DRY ONLY!!!!!!!!!!!!!
