Gütermann’s Maraflex no. 120 is an extremely elastic sewing thread with a beautiful sheen. It is highly suitable for elastic seams in clothing, sportswear, underwear, lingerie, footwear or for decorative seams. With this thread, seams retain 30-60% elasticity when sewn with a double lockstitch, ensuring a pucker-free appearance. Suitable for fine to medium-weight fabric and leather. This sewing thread is made from 100% polyester (PBT) and is exceptionally even, smooth and lint-free thanks to the innovative MCT thread construction technology (Micro Core Technology). For optimal elasticity, it is suggested to use Gütermann’s Maraflex as needle and looper thread. Recommended needle size: NM 70-80. Washable up to 60ᵒC. One spool of Gütermann’s Maraflex no. 120 holds 1500 metres of thread.
