Kelheim Fibres breaks new ground in filtration
For many years, Kelheim Fibres has been working on fibres for filtration applications, boasting a number of well-known commercial products as well as innovative new developments. The use of viscose fibres in papers for tea bags or coffee filters and R&D activities in the sector of beer filtration are just two examples.
Now, the fibre specialists are looking into a new area of applications and are exploring the suitability of their hydrophobic Olea fibre for emulsion separation.
Olea is a viscose fibre with durable hydrophobic properties. The additives used in production are approved for food contact by the FDA and the BfR and at the same time free of silicones. In a series of tests over the next months, the leading manufacturer of viscose speciality fibres will analyse how these hydrophobic properties influence the separation of water/oil mixtures. Preliminary trials have shown an accumulation of oil on the fibre’s surface which then enables the separation of the larger oil droplets.
In a next step, the Bavarians will examine the efficacy of separation of different emulsions, as well as the influence of the nonwoven construction and suitable blend partners.
In order to include the technical and commercial requirements of different potential markets, Kelheim Fibres intends to include industrial partners at a very early stage in this development.
