Transport & Automotive

DIOLEN® Polyester yarns are used as components for new materials in body construction and in the interior trim and fittings of means of transport. They can be found in numerous leading brands of cars and utility vehicles, on public transport and in shipping.

Several pilot spinning lines and our own masterbatch production mean that customised colour combinations can be directly implemented and visualised. Consistent quality management and systematic lab tests guarantee a smooth process that continues after start of production.



Discretion and expertise throughout the textile value chain, from the initial idea to start of production – something that our automotive customers have valued for decades. Our Research and Development experts work with you to develop individual yarn requirement profiles and subsequently monitor all manufacturing processes.
