Mettler Seraflex Thread - T7840

Innovative elastic sewing thread SERAFLEX^®

Highly elastic and versatile: with our 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!

Available in up to 72 colors and 1 featuring size

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.

Excellent elongation properties

Thanks to its innovative raw material PTT, SERAFLEX can achieve an elongation of up to 65%.

SERAFLEX® is the perfect sewing thread for highly elastic seams on all elastic fabrics. Due to its innovative raw material PTT (37% renewable raw material) an elongation of approximately 65% is achieved, making all seams highly elastic!

SERAFLEX® makes straight stitches extremely stretchable. In the best case, even a doubling of the seam elasticity can be achieved compared to seams with conventional sewing threads.

Due to its extremely elastic properties SERAFLEX® is primarily used for ready-to-wear clothing, as well as sportswear and outdoor clothing. It is also ideal for lingerie and underwear. It is also chlorine resistant, making it the perfect choice for swimwear.
