Substrate Innovation: Revolutionary Fibers & Fabric Performance II
New Lyocell Fibers for Wet Wipe Applications
Lenzing AG successfully developed new Lyocell fibers significantly increasing the quat release properties of disinfecting and hard surface cleaning wipes. In the non-woven industry disposable, disinfecting wipes are one of the fastest growing areas. Cellulosic fibers only find limited use within this segment due to tie-up of the active disinfectant from the lotion. The negatively charged surface of the cellulose binds the cationic charged active substances (quaternary ammonium compounds) within the lotion. Lenzing AG developed new Lyocell fibers allowing the use of up to 100% cellulosic material in the wipe, nearly maintaining the release properties of synthetic fibers. By masking the negatively charged surface of the Lyocell fiber, the active substances do not bind to the surface of the fiber, and are therefore available within the lotion to unfold their disinfecting potential. This new developed concept only works with acidic lotions.
