Question: What determines the type of thread used?

Doctor: The type of material you are sewing.  For instance if you are sewing a material that has elasticity you should use either a spun polyester or core  thread.

Question:What is the difference between Spun Polyester and Core Threads?

Doctor: Spun Polyester is made from  polyester fibers which are spun into single yarns then plied into a thread. Core threads are made from a polyester filament core around which is  wrapped a cotton or polyester cover. The cotton wrap provides excellent sewability because it provides good needle heat resistance. Note: The polyester core is stronger than the cotton wrap and spun polyester.

Question:What is the Tex size and how does it help determine the size of the thread needed?

Doctor: Tex Size is a ticket size of sewing thread that is based on the weight of 1000 meters of natural thread. For example if the weight is 400 milligrams the thread would be ticketed T-40. Note: The higher the Tex size the heavier the sewing thread.
