Q. Is polyester thread used in sewing?

Yes polyester threads are used not only in sewing but other thread and fabric work as well. In fact for all sewing needs as well as handcraft works polyester thread is the best suited form of thread. The suppleness of polyester thread matches that of your cloth. To prevent the thread from feeding too rapidly during the use of this thread on a machine it is recommended to wind the bobbin loosely and stitch at a slow to moderate speed. Polyester thread may expand as a result of the severe friction brought on by poor threading.
