Conductive Fibers – Upgrading The Fashion Industry

Conductive Fibers In Fashion. Metallic garments are becoming an integral part of fashion as given their intrinsic properties such as durability, metallic yarns are used in high-quality fashion goods.

Metallic threads give fashion garment an inimitable character and make everyday clothes look chic and attractive. But, what makes these yarns so special is their capacity to conduct electricity.

Most metallic fibres are all-metal made. However, recent advancements allow for classic fibres to be coated with metals. The delicate threads are then spun and knitted via conventional method while retaining the properties of the metals from which they are produced.

Most common choice of metallic strands contains gold and silver, though, aluminium yarns, aluminised nylon, and aluminised plastic yarns are also used.  The process works by taking ‘classic’ fibres and expose them to the so-called ‘metalizing’ process. Here, the metal is heated until vapourisation and then deposited on the fibre. The resultant fibres are thin, flexible, durable, and very comfortable.




Another process involves dipping the fibres into sulphuric acid to create toeholds that, after being soaked in palladium salt and a nickel-plating solution, become encrusted with nickel crystals. The now-conductive fibre is then rigged to a charged copper ingot in a bath, with the result that copper particles electroplate its surface.

Metallic fibres are already used in upholstery, carpets, home textiles, needlepoint embroidery, protective suits, space suits and most party-oriented outfits. However, given the yarn’s conductive capabilities, these fibres are increasingly adopted and used by fashion designers in self-warming jackets, smart knickers, connected underwear (yes, you’ve got that right), and intelligent handbags.

Conductive fibres are much lighter than metallic wires, thus able to the durability of the products, without increasing their weight or wearability. Moreover, constant developments in fashion technology have led to a new wave of fashion garments that contain wearable sensors and act as an extra skin of electronic devices.

Conductive Fibers – Body-Sensing Apparel

With costs falling and usage increasing, connected threads are a growing business, says Hugo Trux, head of the Conductive Fibres Manufacturing Council (CFMC).

As the fibres conduct electricity, the garments can be used as hosts of smart electronics as well. Colin Cork and his colleagues at the Advanced Textiles Research Group at Nottingham Trent University in the UK have embroidered hidden antennae onto shirts using silver-coated thread.




The embroidered antennae are invisible and can be used by devices worn by the user to transmit and receive radio signals or to boost the device’s own transmission range.

More companies use conductive fibres to implant RFID tags and track invaluable luxury garments and goods. Adidas is knitting conductive fibres into its sport apparel lines to produce “textile electrodes”.

These are a few square centimetres in size and pick up signals from the heart and other muscles. The data gathered is transmitted through the garment to a sensor which processes the data and passes it wirelessly to a user’s mobile phone.

The data is then transmitted by an athlete to his coach, or by a patient to a doctor, says Stacey Burr, head of wearable electronics for Adidas.

Building on the foundation of connected fibres, many more companies are developing body-sensing apparel. At the Fraunhofer Institute in Berlin, researchers have come up with textile electrodes that measure the electrical activity of the large trapezius muscle in the shoulder and neck.




The system can distinguish between physical and psychological stress informing a wearer when it is best to pause during exercise.

Conductive Fibers –  ‘Smart-Wear’ Fashion

Attaching conventional electrodes to someone’s body for the same purpose can itself cause them stress, says Torsten Linz, a member of the research team.

Similarly, researchers from the e-textiles lab at Virginia Tech use conductive fabric to shuttle battery power and data to and from miniature gyroscopes and compasses fastened to shirt cuffs and other bits of clothing.

The new trend of ‘conductive fibres’ will soon permeate the broad ‘lifestyle fashion’ market, reckons Joanna Berzowska, head of electronic textiles at OMsignal, a Montreal startup.

Joanna’s company is developing ‘smart-wear’ fashion garments that feel like everyday wear. The garments use silver and steel blends that record and report on the wearer’s body processes, which is then presented to the wearer via a smartphone.

Conductive Fibers – Industrial Use

Besides adding functionality to clothes, conductive fibres have huge potential as a weight-saving material. Every kilo removed from a typical airliner reduces its lifetime fuel cost by roughly $2,200. As such, luxury cars and jets could become lighter and more efficient by replacing the metal wiring with natural and synthetic fibres treated to conduct electricity.

In fact, a cottony yarn branded ARACON, is already used by Airbus and Boeing in some of their luxury jets. ARACON was developed by DuPont as an alternative to its Kevlar fibre, which is used in things ranging from bulletproof vests to drum heads.




Micro-Coax, a firm in Pennsylvania, makes ARACON by coating the synthetic fibres of Kevlar with copper, nickel and silver. The resulting yarn is not just lighter than metal wire, but also much tougher and more flexible.

Conductive fibres are redefining how electrical wirings are used as power-transmission lines are replaced with aluminium and copper-coated synthetic fibres such as Zylon, making power lines at least a third lighter and at least several times stronger, reckons Mr Abel.

More exotic applications are emerging as CanShielding, an Ontario firm is developing a lightweight carbon and silver-fibre aprons to protect x-ray technicians.  The company is also developing a type of material able to absorbs radar signals.

Conductive Fibers – On The Catwalk

Back to personal fashion, smart lingerie is predicted to become the hot trend in the near future. A huge American fashion group has shown interest in a textile called ‘Fabcell’ that uses liquid-crystal inks to change colour when its fibres are warmed by a battery, says its inventor, Akira Wakita of Keio University in Japan.

SwicoFil, a Swiss company, makes a range of conductive fibres, including a gold-coated thread for Rococo Dessous, which produces luxury lingerie.

The conductive fibres business in wearable electronics generated over $22 billion in 2017, and is predicted to rise to $70 billion by the end of 2024 is a clear indicator of an emerging textile-integrated electronics market. The catwalks of London, Milan, New York and Paris are bound to get a lot more interesting.
