Kelheim Fibres GmbH, leading producer of viscose speciality fibres, will showcase their new products at this year’s Zellcheming for the first time.

In addition to the well-known brands Danufil®, Galaxy® and Viloft® nonwoven Kelheim presents an impressive number of speciality fibres which are specifically designed to meet the needs of the paper making industry.

Through the incorporation of Kelheim’s speciality fibres, paper properties can be adjusted according to the individual requirements of the end product. Tear strength and tear resistance, porosity, retention, dewatering or bulk are all properties which can be influenced in this manner.
Beyond this, these viscose specialities can also generate additional functionality in the end product. By the incorporation of each of the fibres Verdi, Bramante, Dante or Bellini, for example, a significantly increased level of absorbency can be achieved. In speciality papers or filters, the viscose fibre DeepDye delivers a high dye absorption capacity and is therefore ideally suited for the incorporation in filters for the decolouration of the waste water from dye houses.

Poseidon is a fibre with ion exchange properties – integrated in papers or wet laid fabrics, it too serves its purpose mainly in filters: when used in tea or coffee bags, it can be used to soften drinking water, for example. By loading the fibres with metal ions such as silver or copper, it is possible to deliver an antimicrobial effect for medical applications.

The advantage of all these fibre specialities: they are manufactured from wood pulp - the same basic raw material used in the paper industry – and can therefore be easily incorporated in the papermaking process.

Kelheim Fibres has been a regular supplier to manufacturers of speciality papers for many years. Kelheim offers short cut fibres with a linear density 0.75dtex to 9dtex in cut lengths from 4mm to12mm and is therefore able to fulfil the needs of a wide range of customers and production processes. Fibres with engineered cross sections offering different functionalities as well as dry short cut fibre for the airlaid industry complete Kelheim’s range of products.

With their own in-house technical centre for paper development, Kelheim Fibres is able to intensively test these products during development and present the results as part of the product launch. In addition to this, close cooperation with the professionals of the Institute for Paper, Pulp and Fibre Technology (part of the Graz University of Technology), allowed the positive influence of viscose fibres on paper properties to be independently tested and proven.

A detailed report of the results of this research will be presented to the public by Dr. Ingo Bernt, a member of Kelheim’s R&D team, at this year’s ZELLCHEMING general meeting.

At the same time, a team from Kelheim Fibres is looking forward to your visit to our stand at ZELLCHEMING expo – visit us in Hall 2, Stand 207!
