Sabaflex is a sewing thread made from PTT (Polytrimethylene terephthalate) continuous filament. It is made with 37% biopolymers from renewable resources. PTTs feature high elasticity, soft feel, resistance to yellowing, extreme durability, but also excellent elongation behaviour and good crease resistance.

Stretch it! Sabaflex is the highly elastic sewing thread for all elastic materials. It provides a stretch reverse for all seams, and makes all seams become highly elastic. Sabaflex is suitable for closing and decorative seams and guarantees highest elongation and best sewability. Among all sewing threads, Sabaflex is rightly known as the all-rounder for all elastic materials and it is an indispensable product for the apparel industry, when seams are supposed to feature maximum elasticity. 

Hohenstein Laboratories confirm the industrial wash resistance of Sabaflex. Consequently, Sabaflex is certified with the PRO-care certification according to DIN EN ISO 30023. Besides, Sabaflex is certified according to STANDARD 100 by OEKO-TEX®, 93.0.4233.

Based on its extremely elastic properties, Sabaflex is primarily used for apparel. Among others it is used as sewing thread for ladieswear & menswear, as sewing thread for sportswear & outdoor, as sewing thread for underwear & lingerie, as well as for workwear. Moreover, Sabaflex is also used for shoes & accessories and home interior.
