Not true. If you have attended one of Bob’s seminars, you have seen hands-on proof that this is a myth. Thread tearing into a fabric has nothing to do with the thread fiber type but with the strength of the fibers (both in the thread and in the fabric). Some cotton thread (such as glazed cotton) can be stronger and more abrasive than polyester." Bob Purcell, Superior Threads, Education,
