Mettler Seraflex 100% PTT Elastic Thread

Mettler Seraflex is a 100% PTT elastic sewing thread designed for use on stretch and jersey fabrics, available on 130m spools. Its PTT composition, made with 37% renewable raw material, gives the thread resilience and stretch recovery. When sewn with a straight stitch and reduced tension, Seraflex can offer up to twice the stretch of seams made with conventional threads.

Well suited to womenswear, menswear, childrenswear, sportswear, outdoor wear, lingerie, and underwear. Although measured in Tex rather than thread weight, the thickness is closest to a 50wt sewing thread. Seraflex is certified to STANDARD 100 by OEKO-TEX®.

Recommended needle sizes: 70/10 or 80/12, using a Universal, Jersey, or Stretch needle according to the fabric.
