100% PTT (Polytrimethyleneterephthalate)

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!
