Is fabric safe for bunnies?

So my bunny has a habbit of chewing my clothes and so was planning to put a large scrap of an old plain white T of mine in his hutch as a sort of "this is yours, these are mine" deterent. Is this safe? If not what else could I do? I've been telling him no and putting him back in his hutch when he does it but it's not doing anything and Im not willing to use biter spray on my clothes. He's got loads of chew toys: wooden fruit shapes, Vegtable fling and chews and a rope and block toy that he sleeps with. He's also chewed through his plastic bell ball and the bunny rattle, he has plenty of both hay and straw in his hutch that he uses as his bed and I can't see anything else that could possibly deter him. Help. Please?
