The black fibre receives its specific properties by the incorporation of electrically conductive additives into the fibre’s core. As a result, the functional additives are evenly distributed in the whole fibre, while at the same time the typical properties of the viscose fibre – as for example its high absorbency – are preserved, the company reports.

According to the manufacturer, the first tests with these fibres that have been successfully produced on a laboratory scale have shown a significant increase of the fibres’ electrical conductivity in comparison to a standard viscose fibre. Depending on requirements, Kelheim fibres are said to produce fibres in the middle conductivity range from about 10-4 S/m to 0,1 S/m.

Applications

The functionalized fibre could be used in protective work wear for electrostatic discharge, for the protection of electronic components or humans. Used as humidity sensor – wherever an immediate detection of moisture is required – the dissipative fibre is said to offer a significant advantage. The fibres could be used in bed pads for the health and care sector, as well as in roof linings that detect possible leakages.

“This topic is as fascinating as it is wide – up until now, we have created a strong foundation. Depending on the market’s requirements, the future way of the functionalized fibre can lead in different directions. From now on it is important to follow the specific demands of our customers and of different applications in the further development of the fibre,” commented Dr Nina Köhne, R&D project manager at Kelheim Fibres.

Kelheim Fibres

Kelheim Fibres is one of the leading producers of viscose speciality fibres. The company is focused on developing innovative products, flexible technologies and strong customer orientation, as well as active environmental protection.

From the company’s production plant and headquarters, located in Kelheim in Southern Germany, its viscose fibre products are used in widely diverse applications ranging from fashion, hygiene and medical products, to the nonwovens industry. Approximately 90,000 tons of viscose fibres are produced and tested every year at Kelheim in South Germany.
