FAQ
-
PTT is produced through polycondensation. The fibre is formed using the melt spinning process.
-
PTT combines high elasticity with a soft feel and excellent stretch and recovery behaviour, making it particularly suitable for elastic seam applications.
-
Yes. PTT offers high elasticity and outstanding stretch and rebound properties, allowing seams to maintain flexibility under dynamic stress.
-
Due to its soft feel and elastic behaviour, PTT supports comfortable seams, especially in stretch garments.
-
Yes. PTT has good resistance to yellowing, contributing to long-term visual stability.
-
PTT is extremely durable and provides good resistance to repeated mechanical stress.
-
No. PTT has good crease resistance, supporting dimensional stability in garments.
-
Certain PTT variants, such as those based on Sorona®, contain a proportion of renewable raw materials and are produced with reduced energy consumption.
-
PTT has a melting point of approximately 225°C.
-
PTT threads are commonly used in stretch apparel, sportswear, athleisure and applications requiring elastic seams with high recovery performance.
