Kelheim Fibres outlines the ‘endless possibilities’ from viscose specialty fibers




KELHEIM, Germany, September 12, 2016-

Unlike other cellulosic fibres such as cotton or wood pulp, viscose fibres are distinguished by their well-defined and reproducible properties that allow them to be designed to meet the needs of processing steps and adapted to each application. For example, the porosity and surface of a filter can be precisely controlled by adding viscose fibres with different cross-sections. The incorporation of functional additives into viscose fibres allows the optimization of the fibres in respect of the intended application, for example for the removal of tannins from beer.

The advantage of functional viscose fibres: as the additives are incorporated in the fibres they do not impact the physical properties of the filter and can not migrate into the filtered product but can still function effectively. As viscose fibres are manufactured from renewable raw materials incineration at the end of filter life is CO2 neutral, or – if the residue in the filter allows – they can be composted, an ideal disposal route for precoat filter cakes in the beverage industry.
