Highly elastic and versatile: with Mettler 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%.
Mettler recommends 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.
