Mettler Seraflex Thread

Innovative elastic sewing thread SERAFLEX®
Seraflex sewing thread is highly elastic and versatile and is exactly the right thread for all stretch fabrics. The secret is its special composition with the innovative raw material PTT allowing 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 thread.
Seraflex is primarily used for clothing such as outdoor and sportswear women's men's and children's clothing lingerie and underwear.
