–  an innovation that protects life.

Every year about 400 people die of fires – in Germany alone (Source: German Fire Brigade Association). 95% of them die from the toxic flue gases. Frequent cause for this: Textiles can be real fire accelerators.

The use of flame-retardant fibers and yarns can often prevent worse things from happening.

Polyester fabric made of FLAMEX complies with German technical building regulations and is classified as a flame-retardant building material (material class DIN4102-B1) according to DIN 4102-1.


FLAMEX by Carl Weiske stands for a permanent flame-retardant effect thanks to flame-retardant phosphorus-based co-polymers firmly anchored in the fiber. This ensures that the flame-retardant function of the textiles is maintained during use and washing.

In the event of a fire, the polyester melts and the surface area is reduced. In addition, a film of phosphorus is formed, which interrupts the oxygen supply that promotes fire.

FLAMEX textiles are therefore flame-retardant and meet the most important national and international standards for preventive flame protection.

Whether at home or on the road – the fields of application for FLAMEX yarns are manifold:




  • 100% FLAMEX made of polyester bright 1,3 dtex/38 mm
  • 100% FLAMEX made of polyester bright 3,3 dtex/51 mm
  • 100% FLAMEX made of polyester semi dull 1,6 dtex/38 mm


  • Staple fibre yarns up to Nm 100
  • OE Yarns up to Nm 50
  • Textured filament yarns (also twisted on request)

GREENTEX polyester fibres and yarns are made from recycled PET bottles. 100% of the recycled bottle polymer is used in the production of GREENTEX.

Carl Weiske Produkte


Our latest polyester yarn FLAMEXGREEN is made from recycled PET bottles and is also flame retardant.

Instead of virgin polyester, FLAMEXGREEN uses at least 60% recycled PET bottles (post-consumer).

Cool Plus

The COOLPLUS technology refers to cooling and moisture-transporting polyester yarns which drain sweat off from the skin surface particularly fast – keeping your skin cool
and dry for a longer period during sports activities.
