KELHEIM, Germany — December 18, 2017 — With the newly developed viscose fiber speciality Danufil® QR, Kelheim Fibres has mastered a challenge in the area of disinfection wipes. So far, the use of viscose fibers in these antiseptic wipes has posed a significant problem in spite of their excellent fluid handling properties: the fibers 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 fibers are negatively charged which is why up to 80 percent of the quats are tightly bound to the fiber — meaning they are no longer available for their actual purpose.
With the viscose speciality Danufil QR, Kelheim has developed a positively charged viscose fiber that can reduce this undesired effect to less than 10 percent. As a result, by far the largest proportion of the quats is available for effective cleaning.
Danufil QR receives its functionality through the incorporation of a completely bio-degradable additive into the fiber’s core. Therefore, the functionality is evenly distributed and cannot migrate from the material.
While viscose fibers are long established raw materials for other hygiene, medical or food applications, Danufil QR offers all the well-known benefits of viscose fibers such as absorbency, softness and skin- friendliness for disinfectant wipes.
Kelheim’s viscose fibers also score high points for eco-friendliness, particularly in convenient disposable products: Danufil QR is made of 100-percent renewable raw materials. The cellulose used for these fibers comes exclusively from FSC- or PEFC-certified sources.
In addition to this, Danufil QR has successfully taken its first steps in practice. Sample quantities for tests are immediately available.
