Kelheim Fibres developed viscose fibre “with a fingerprint”

May 30, 2013. /Lesprom Network/. Kelheim Fibres, experts in manufacturing viscose speciality fibres, offers an innovative solution. In cooperation with Tailorlux, the specialist for anorganic phosphors, Kelheim has developed a viscose fibre “with a fingerprint”, as the company said in a press release received by Lesprom Network.

To achieve this, luminescent pigments from Tailorlux are incorporated in the viscose fibre matrix during the spinning process – so the pigments are intrinsically bound to the fibre and durable. Tailorlux produces customised pigments in a range of more than 300 billion combinations, each with its own individual spectrum.

Fibres incorporating these pigments bear their characteristic spectroscopic fingerprint in the body of the fibre; the fibres – as well as the products made using them - can be precisely identified and are therefore impossible to forge.

Validation is by light spectroscopy, a widely recognised and uncomplicated method. The pigment can be detected in a non-destructive or a destructive examination (for example in the ash of a product). For quick checks in the field, Tailorlux offers a simple hand scanner.

Kelheim Fibres’ latest development is primarily aimed at the paper industry: Viscose fibres can be easily integrated in the papermaking process and remain – together with the pigments incorporated in the fibre - in the paper.
