Mettler SERAFLEX® Fantastic Stretchable Thread

Innovative elastic sewing thread SERAFLEX®

Highly elastic and versatile: with SERAFLEX sewing thread, you are buying exactly the right thread for all stretch fabrics. The secret is its special composition: The innovative raw material PTT allows the sewing thread to stretch up to 65%. We recommend using the sewing thread exclusively for straight stitches. When used as needle and bobbin thread and with a thread tension as loose as possible, its full elasticity comes into effect. This way, SERAFLEX even achieves a sewing elasticity that is twice as high as that of conventional sewing threads.

Whether as sewing thread for women's, men's or children's clothing, for sportswear and outdoor as well as for underwear and lingerie: SERAFLEX masters every challenge!

Instructions for use:

SERAFLEX should be used as both, needle and bobbin thread. Thread tension should only be “as tight as necessary”, meaning as loose as possible.

The bobbin thread should also be wound with as little thread tension as possible to prevent the thread from stretching beforehand. The sewing thread is suitable for the sewing machine.

Due to its innovative raw material PTT (37% renewable raw material) an elongation of approx. 65% is achieved, making all seams highly elastic.
