It is now possible to coat continuous filament yarn with 100% Silver (meaning without any adhesive layer underneath) by a new process called plasma metal coating.
Invented by EMPA Sitzerland, this wordwide unique and patented technology has the potential to open new markets as it combines the characteristics of silver (such as high conductivity) with those of a filament yarn (such as touch, workability, ...) while providing an excellent adhesion of the silver.

Why Plasma Silver Coated Yarns?
SwicoSilver 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. SwicoSilver 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.
SwicoSilver yarns are the only ones in the world that provide flexiblity, very high conductivity and longevity thanks to its new production process, the Plasma Metal Coating, 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 other silver coated yarns have - brittleness and low adhesion - is inexistent for SwicoSilver yarns.

- highly conductive
SwicoSilver yarn meet high conductivty levels of up to 1 ohm/cm. Even lower conductivity values can be reached by SwicoSilver type HiCon (abt. 0.06 ohm/cm).
- textile touch
Despite being coated with silver, SwicoSilver yarns feel like a normal textile yarn and are 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 silver only
There is no layer of any other metal or adhesive substance underneath like it is with other metalization processes. Yet, SwicoSilver provides 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.
Furthermore, thanks to the coating with pure silver, SwicoSilver yarns also comprise the characteristics of silver, which are:
- antimicrobial
- antifungal
- static dissipation
- shielding from radiation
- shielding from electromagnetic force

PLASMA SILVER COATED POLYESTER DTY YARN
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:
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.
*: for even lower conductivity values, please refer to "SwicoSilver HiCon".
