SWICOFIL - Yarn and fiber expert.


Have you ever imagined what products you could develop if one could coat yarn with precious metals of all kind without any adhesive layer underneath? This is no longer fiction - it is reality. Plasma Metal Coated Yarns, the exclusive opportunity of coating yarns with the metal of your desire.
It is now possible to coat continuous filament yarn with the metal of your choice without any adhesive layer underneath by a new process called plasma metal coating.

Invented by EMPA Switzerland, this wordwide unique and patented technology has the potential to open new markets as it combines the characteristics of the metal (such as conductivity) with those of a filament yarn (such as touch, workability, ...) while providing an excellent adhesion of the metal.


Why Plasma Metal Coated Yarns?

Coating a filament yarn by the plasma coating method gives much better wear, a perfect level coating and little to no conductivity fluctuation compared to usual techniques of coating yarn with metal. Plasma metal coated yarns are easy to process in the textile chain and products on the fashion side have a wonderful noble appearance. Furthermore, they are easy to adapt to customer's requirements such as count, conducivity or base yarn material.

Plasma metal coated yarns are the only ones in the world that provide flexiblity, very high conductivity and longevity thanks to its new production process, where no chemo-galvanical methods are used. 
This is a huge advantage for demanding applications. The final product is easy care. The big problems that all metalized yarns have - brittleness and low adhesion - is inexistent for Plasma Metal Coated yarns.

Compared to any other metalized yarn, Plasma Metal Coated yarns convince with the following characteristics:
  • textile touch
    Despite being coated with silver, plasma metal coated yarn feel just like a normal textile yarn and is just as versatile.
  • exceptional adhesion
    The silver coating holds perfectly onto the yarn. Due to the plasma coating production process, the silver is not brittle and will not crumble off the yarn.
  • very regular coating along the yarn
    Ideal for automation applications, where uniform conducitvity is important to keep performance at a steady level and reaction margins extremely narrow.
  • coated with the metal of choice only
    There is no layer of any other metal or adhesive substance underneath like it is with other metalization processes. Yet, Plasma Metal Coated Yarns provide excellent adhesion of the metal on the yarn - much better than traditional methods.  
  • tailored upon your requirements
    Additional to the standard programme, SwicoSilver yarn can also be made with the properties you need. This includes conducitivity values, base yarn material counts or twist. We do everything so that the yarns are easy to process for you.

Plasma Metal Coated yarn can be tailored upon your requirements.
Not only concerning the count (from a fine dtex 8 mono- or multifilament up to a coarse dtex 550 high tenacity multifilament) are plasma metal coated yarn highly flexible but also in reference to what materials can be coated. So far, the following materials have been used for this process:

  • Polyester (PET)
  • Polyamide 6.6
  • Polyamide 6
  • Viscose (CV)
  • Silk
  • Meta-/ Paraaramide
  • Vectran

Also, friction textured HE or Set yarn can be coated which provides a "geometric" elasticity to the product.
Everything is possible as long as the yarn is a continuous filament yarn with a count of between dtex 8 - dtex 550.
Base material: continous filament yarn (mono and multifilament)
Count range: dtex 8 - dtex 550
Twist: no restriction
Lowest possible conductivity: depending on the metal 
Possible metals: every metal


For what kind of application are Plasma Metal Coated Yarn suitable?
  • fabrics for decoration
  • high end fashion
  • luxury menswear in pin stripes
  • sewing / embroidery threads
  • fabrics for clerical applications
  • home furnishing
  • carpets
  • medical end uses
