Kelheim Fibres, manufacturers of specialty viscose fibres, has developed a new viscose ‘fibre with a fingerprint’. To achieve this, luminescent pigments from Tailorlux are incorporated in the viscose fibre matrix during the spinning process – so they are intrinsically bound to the fibre and durable. Tailorlux produces customized pigments in a range of more than 300 billion combinations, each with its own individual spectrum.
The new fibre aims to protect products from forgery as fibres incorporating these pigments bear their characteristic spectroscopic fingerprint in the body of the fibre, allowing the fibres and the products made using them to be precisely identified.
Germany-based Kelheim’s latest development is primarily aimed at the paper, textiles and nonwovens industries, wherever products need an invisible but unique identification mark. These fibres can ensure the traceability of filters – or they can help to control the compliance of predetermined supply chains in the textile industry.
