Sabaflex is a highly elastic sewing thread for stretchy materials, made from PTT (Polytrimethylene terephthalate) continuous filament. Sabaflex makes all seams become highly elastic. Sabaflex is suitable for closing and decorative seams and guarantees highest elongation and best sewability. PTTs feature high elasticity, soft feel, resistance to yellowing, extreme durability, but also excellent elongation behaviour and good crease resistance.
