Has anyone come across a tartan or kilt fabric made from wool treated to be washable?

I was just doing a bit of tidying up and came across a ball of woolen yarn marked 'washable' and I suddenly wondered if there is a mill anywhere using wool yarns treated to be washable.

I do quite a bit of knitting, and am old enough to remember wool garments getting into the washing machine by accident and coming out all felted and shrunk. Nowadays, if you get the right yarn and use the right program woolens can be machine washed with no ill effects.

So - is there such a thing as a washable tartan fabric?
