SWICOFIL - Yarn and fiber expert.


An elegant yarn that combines conducitvity and the textile touch without losing workability, adhesion or stability - this is SwicoGold, 24K Gold coated filament yarns.
It is now possible to coat continuous filament yarn with 100% 24K Gold (meaning without any adhesive layer underneath) by a new process called plasma metal coating.

Invented by EMPA Switzerland, this wordwide unique and patented technology revolutionizes the Gold yarn industry as it combines the characteristics of Gold (such as conductivity) with those of a filament yarn (such as touch, workability, ...) while providing an excellent adhesion of the Gold.

Why Plasma Gold Coated Yarns?

SwicoGold yarns are a part of the Plasma Metal Coated Yarns programme. 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. SwicoGold 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.

SwicoGold yarns are longlasting as SwicoGold yarns are the only one in the world where 24K Gold is brought straight onto the base yarn. There is no silver or copper layer underneath the Gold
This is a huge advantage for demanding applications. The final product is easy care. The big problem that all other Gold coated yarns have - the underlying silver or copper oxizidizing through the gold coating, turning the gold black therefore - is inexistent for SwicoGold yarns. They can be washed without hesitation and without having to fear the gold to turn black.

Compared to any other metalized yarn, SwicoGold yarns convince with the following characteristics:
  • excellent washing behaviour
    After 60 household washing cycles, there is 90-95% of metal still on the SwicoGold yarns according to tests conducted by EMPA Switzerland.
  • 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 Gold only
    There is no layer of any other metal or adhesive substance underneath like it is with other metalization processes - SwicoGold yarns will therefore not start to oxizie as there is no silver / copper involved.
  • inertness
    SwicoGold yarn, composed of only the base material of your choice and gold, is technically inert which makes it very suitable for medical applications where characteristics such as corrision resistance and high conductivity are crucial for new fields of technologies.
  • tailored upon your requirements
    Additional to the standard programme, SwicoGold yarns can also be made according to 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.
  • very fashionable
    Products on the fashion side with SwicoGold yarns have a wonderful noble appearence due to the yarn's elegance and fineness.

Furthermore, thanks to the coating with real 24K Gold, SwicoGold yarns also comprise the characteristics of gold, which include inertness

Additional to the stock service, SwicoGold yarn can also 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) 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: continuous filament yarn (mono and multifilament)
Count range: dtex 8 - dtex 550
Twist: no restriction
Lowest possible conductivity: abt. 10 ohm/cm
