The 20S\/2 construction is a heavier-weight polyester—denser than 40S\/2—so each cone is larger and better suited to denim, canvas, upholstery, bags and other sturdy materials. Tortoise focuses on consistent quality: colorfastness, measured breaking strength, low hairiness and controlled variation for smooth stitching on single-needle machines, sergers and overlocks.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this thread perform on heavy fabrics and frequent use?\u003c\/h3\u003e\n\u003cp\u003eThe 20S\/2 polyester is made to resist stretching and to keep seams secure in demanding applications.
