High-performance insulation materials, disinfectant wipes and supply chain transparency –
|– viscose fibre manufacturer Kelheim Fibres will present solutions for these and more topics at this year’s Techtextil. With dry short cut viscose fibres, Kelheim Fibres contributes to energy saving: Fibres with an extremely fine titre are processed along with pyrogenic silica to vacuum insulation panels (VIPs). With their specific properties, Viscose fibres contribute reinforcement and allow for permanent dimensional stability.
Vacuum insulation panels offer the same insulation effect as rock wool with only one tenth the thickness. Such panels are used for example in refrigerators and freezers, as well as in building insulation. Transport logistics that demands an uninterrupted cold chain is another promising future market for these speciality fibres. Fresh from Kelheim’s R&D laboratory comes the new viscose speciality fibre, Danufil® QR. It is specifically designed for use in disinfectant wipes. While standard viscose fibres, due to their negative ionic charge, bind up to 80% of “quats” (quarternary ammonium compounds, a common disinfectant) and so hinder their actual purpose, the positively charged Danufil® QR fibre can reduce this undesired effect to less than 10%. Softness, excellent fluid management and full biodegradability are the typical properties of viscose fibres – with the use of Danufil® QR, disinfectant wipes can now also benefit from these.
