Material Developments in Wipes I

Activated Viscose Fibres for Utilisation of Disinfectants with Cellulosic Wipes

With the newly developed viscose fibre speciality Danufil® QR, Kelheim Fibres has mastered a challenge in the area of disinfection wipes. So far, the use of viscose fibres in these antiseptic wipes has posed a significant problem in spite of their excellent fluid handling properties: the fibres bind certain disinfectant substances which severely interferes with the wipes‘ function. The active substances are quaternary ammonium compounds. These so-called „quats“ are positively charged. Standard viscose fibres are negatively charged which is why up to 80% of the quats are tightly bound to the fibre – meaning they are no longer available for their actual purpose. 

With the viscose speciality Danufil® QR, we have developed a positively charged viscose fibre. This fibre receives its functionality through the incorporation of a – completely bio-degradable - additive into the fibre’s core. Therefore, the functionality is evenly distributed and cannot migrate from the material. To prove the functionality standard viscose, Danufil® QR and fibre blends were treated with quat solutions of different concentrations. The solutions were analysed in terms of free quats remaining in solution. In the case of Danufil® QR 80 – 90 % of quats remain free in solution whereas regular viscose immobilises more than 70 % of the quats. Kelheim’s viscose fibres also score high points for eco-friendliness, particularly in convenient disposable products: Danufil® QR is made of 100% renewable raw materials. The cellulose used for these fibres comes exclusively from FSC®- or PEFCTM-certified sources. Subsequently, Danufil® QR offers all the well-known benefits of viscose fibres such as absorbency and distribution of lotion, softness and skin-friendliness for disinfectant wipes.
