Tersuisse, your Polyester high tenacity yarn partner in raw white and spun dyed


Customization with Tersuisse includes the following among other points:

  • food contact applications
    Any polyester high tenacity yarn in the Tersuisse program can be supplied with FDA approved spin finishes.
  • taslanized
    Taslanzied high tenacity Polyester multilfilament yarn for applications where a better grip or a higher volume are important.
  • warping
    Tersuisse has modern warping equipment for high tenacity Polyester multifilament yarns - we are able to offer the yarns on weaving beams.
  • spundyed
    Tersuisse is today the only European producer of spundyed (non black) Polyester high tenacity yarns. One of the most important topics is the possibility of producing non bleeding shaed. 



The below oversight shows the standard programme of Tersuisse for PET high tenacity yarns in spundyed. Shades marked with a star (*) are colours that do not bleed. Shades marked with two stars (**) are colours that do most likely not bleed.

PET high tenacity yarns are available in various colours.


  • ability to offer spundyed shades that are NOT bleeding (even in sea water)
  • proximity to the European markets
  • the flexibility to adjust to customers needs in terms of product creation or minimum quantities
  • the ability to create new colours (even exclusivities for a customer are possible)
  • the high quality level
  • the ability to offer twisted and plied yarns
  • Tersuisse's ability to offer taslanized yarns in the same colour (eg. to give ropes a much better grip)
