Creation of 24 carat gold yarn – the best Christmas gift

Nov '11
True luxury has only one color – gold. A nanometer-thin layer of pure gold now lends ties and pocket handkerchiefs that authentic gold sheen, thanks to a new Empa-developed process. The yarn, which is coated using a high-tech plasma process, is soft and easy to weave. It is also washing machine compatible. A limited number of gold ties will be placed on the market before Christmas, making a truly exclusive present. Further fashion accessories will follow in 2012.

Gold radiates with a violet hue, at least when it is sprayed onto a surface atom by atom, as can be seen by looking into a plasma coating plant when in operation. This particular plant, which is about as large as a household refrigerator, can be found on the premises of the Tersuisse spinning mill in Emmen.

Inside the apparatus a piece of gold is bombarded with fast moving argon ions which knock atoms off the metal surface. These gold atoms fly off and land on a polyester fiber which is slowly pulled through the machine. This is the beginning of the production process which for the first time in the world creates a textile material permanently coated with a durable layer of gold. The precious metal remains attached to the fiber even when it is rolled, kinked, woven in a loom and given a final wash.

The textile specialists at Empa in St Gallen had been researching for ten years to find a method of finely dividing titanium, aluminium, steel, copper and silver and then allowing these powdered metals in atomic form to rain onto polyester fibers. Originally the project aimed to create silver coated fibers, for which there were ready markets. Silver coated fibers possess an antibacterial effect, something which is of interest to sock manufacturers.

In addition fashion designers were seeking durable silver coated textiles. And furthermore, silver conducts electricity extremely well, making the Empa-developed fiber eminently suitable for use in various sensors and as an antistatic filter material for industrial applications.

Sooner or later the project partners had the idea that what was possible with silver might also work with gold, so in January 2010 they began work on the "Gold Fiber Project". Nowadays production in the coating plant has reached a stable level. The first kilometer was generated in the summer of 2011 and in 2012 production is expected to increase further.

Further processing of the fiber is completed by two project partners, the Weisbrod-Zuerrer AG spinning mill in Hausen am Albis and the embroidery firm Jakob Schlaepfer in St. Gallen.

One of the first customers for the gold fiber was Weisbrod-Zürrer AG, a spinning mill which specializes in exclusive decorative textiles, ties and accessories and which has also partnered Empa projects in the past. Attempts had already been made previously to create a gold tie using conventional techniques. A textile fiber was wound with the finest gold wire in the same way a guitar string is made.
