no, take a carpet fibre with a set of tweezers, offer it to a flame, not petrol lighter a normal lighter, then if it crumbles (ashes) & smells like burnt hair its natural.(wool), if it melts & beads it synthetic. nylon smells like cellery, polyprop smells like fuel, paraffin. acrylic smells aromatic. cotton smells of burning paper. polyester smells of strong pleasent aroma. lucozade will be more difficult to remove if its wool, wool is easy to dye & tan. regards char
