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.
