SINFLEX — Stretch Sewing Thread

The solution for sewing knits, elastane, and everything that stretches.

Sinflex is a sewing thread developed specifically for stretch fabrics. Where a conventional thread would snap at the first pull, Sinflex moves with the fabric without breaking — thanks to a next-generation polymer (PTT) that gives the thread a natural elongation of up to 60%.
The key advantage: Sinflex produces seams with up to twice the elasticity of those sewn with conventional threads, using the straight stitch of your regular sewing machine. No overlock or special stitches required — simply replace your usual thread with Sinflex (both as top thread and in the bobbin) and sew with a standard straight stitch.

Ideal for
•    Knit fabrics, jersey, and fabrics with elastane
•    Swimwear and beachwear
•    Sportswear, leggings, and activewear
•    Lingerie and underwear
•    Children's and baby knitwear
•    Cuffs, collars, waistbands, and any seam that needs to stretch

How to use
Use as top thread and in the bobbin, with straight stitch and regular stitch length. Set the thread tension as low as possible.

Recommended needle: jersey or stretch needle, 70-80 (Metric) / 10-12 (Singer).

Care: Machine washable at 60ºC. Iron at medium temperature. Resistant to rubbing, light, and perspiration — colours stay vibrant wash after wash.
