Kelheim Fibres VILOFT® - Marketing Cooperation with Lenzing Successful
At the Paris textile fairs in February 2010 Kelheim Fibres GmbH and Lenzing announced the launch of a partnership intended to increase the profile of Kelheim Fibres
VILOFT® speciality viscose fibre product in international markets. For the Chinese market this cooperation was launched at a press conference at Intertextile in Beijing in March.
The feedback from the market has been positive, and already new markets are being opened for VILOFT® fibres. " We are particularly pleased to see the way in which Lenzing are
using their international merchandising networks to link Brands in one region with suppliers in another," says Matthew North, Commercial Director of Kelheim Fibres.
The unique flat cross section of VILOFT® fibres generates a thermal warming effect in fabrics by creating air pockets in the yarns, and also offers enhanced softness in many
fabric types. "These properties have helped establish the position of VILOFT® in Europe in the past, and we are confident that the cooperation with Lenzing will further drive
sales in overseas markets," continues North.
The cooperation between the two companies is already generating additional sales of VILOFT® fibre in the Chinese market, further consolidating the strong growth seen in 2010,
which is already confirmed as a record year for the fibres.
VILOFT® fibres are certified to the Oekotex 100 standard and Kelheim Fibres GmbH has succeeded in securing FSC certification for its range of viscose staple products.
Certification by the Forest Stewardship Council confirms that the raw materials used by Kelheim Fibres are sourced from sustainably managed plantations, underlining the
fibre manufacturer's commitment to respect the environment at all stages of the manufacturing process.
Kelheim Fibres GmbH is one of the world's leading producers of high quality speciality fibres. The company focuses on developing new markets for innovative fibre developments
and is known for its excellent customer service.

New Study: Viscose fibres improve paper properties Kelheim Fibres presents results at Zellcheming
Kelheim Fibres, sole manufacturer of short cut viscose fibres for paper applications in Europe, presented the results of a newly conducted research
at this year`s Zellcheming in Wiesbaden.
The work carried out has shown that speciality papers can benefit in a number of ways from the incorporation of Kelheim`s new fibres.
By the choice of the appropriate viscose fibre cross section the density of the paper can be precisely controlled: the density of the paper sheet
decreases in proportion to the surface area of the fibre added.
In the same way, viscose fibres are used to improve and control the porosity of a paper - a crucial point for example in the production of tea bag or
cigarette papers - or to modify the double fold properties of a sheet, an important factor for currency papers.
Even small quantities of viscose fibres can enhance the tear resistance of speciality papers: by the incorporation of 10% viscose fibres, the tear
resistance of the paper can be increased on average by 40%! At the same time viscose fibres can improve the tear strength of the paper. In this manner
an improvement in tear strength with a simultaneous increase of tear resistance is possible - which cannot be achieved by simply increasing the level of refining.
As well as this, papers incorporating viscose fibres generally exhibit better dewatering properties and, depending on the additive incorporated in the fibre,
improved retention properties.
Furthermore, modified viscose fibres can add specific functionality to a paper.
Examples of Kelheim's products with added functionality are the fibres Poseidon and DeepDye. Poseidon is a viscose fibre with inherent ion exchange properties.
In contrast to loose ion exchange granulates, it is possible to incorporate Poseidon fibres in papers or nonwoven fabrics and design filtration cartridges of
any shape. Poseidon can be used for water softening, for example in tea bags or coffee pads or for the filtration of heavy metals for recycling purposes.
Poseidon can remove destructive acids from all kinds of liquids and it can be used to generate an antimicrobial effect in a product by charging the fibres
with metal ions such as silver or copper.
Deep-Dye is a chemically modified viscose speciality fibre with a dye absorption capacity up to 40 times higher than that of standard viscose products.
Originally developed to optimise the dyeing process of textiles made out of viscose and PET, a wider range of possible applications has since been discovered -
the fibre can be used in all areas which require fast and effective dye absorption, for example in filtration cartridges for the decolouration of the waste water.
With this wide range of products Kelheim Fibres is an ideal partner for the paper industry. The already impressive list of fibres developed and optimised for the
paper industry is completed by the ability to create individual, tailor-made solutions for the different needs of the various paper manufacturers.

Kelheim Fibres to present New Functional Fibres at IDEA:

Kelheim Fibres GmbH, the leading producer of viscose speciality fibres, will showcase a wide range of highlights at this year's IDEA in Miami.
In addition to the well-known brands Danufil®, Galaxy® and Viloft® nonwoven Kelheim presents a number of fibres
with new and distinctive properties.
Extremely high absorbency is the shared characteristic of the new fibres Verdi, Bramante, Dante and Bellini. Beyond that they offer various special
effects such as excellent dispersability in water, a gel effect on the fibre surface or outstanding self-bonding properties. As a result these new
fibres are ideally suited for many potential applications - from medical and hygiene products to filters and speciality papers. Coagulating wound
dressings, absorbent blotting papers or extra tear- resistant banknotes and tea bags are just a few of numerous products which derive their typical
properties from Kelheim's viscose specialities.
Along with the new extra-absorbent fibres, Kelheim Fibres introduces further innovations:
Deep-Dye is a chemically modified viscose speciality fibre with up to 40 times higher dye absorption capacity than a standard viscose fibre. Originally
developed to optimise the dyeing process of viscose textile products, this fibre also offers interesting properties for non-textile end uses: These highly
specialised viscose fibres are processed to make papers and nonwovens which can easily be converted to any form required - and therefore can be used, for
example, in filtration cartridges for the decolouration of the waste water of dyeing factories.
With the equally new speciality fibre Poseidon, Kelheim Fibres launches for the first time a viscose fibre with ion exchange properties.
The advantages of Poseidon fibres in comparison with ion exchange granulates are clear: the active substance is packed into in the fibre and simplifies the
further processing. Integrated in papers or nonwovens, these fibres serve their purpose mainly in filters, e.g. for water softening of potable water via tea
bags or coffee pads.
By charging the fibres with metal ions such as silver or copper it is possible to achieve an antimicrobial effect for medical applications.
In addition to the easy processing the main advantage of Poseidon fibres is the high transfer rate: Due to the very small ion exchange particles, the high
number of fine and short viscose fibres in the paper and finally the accessibility of the viscose fibre, we obtain a very large active surface which enables
a very effective application", explains Walter Roggenstein, head of Kelheim Fibres' R&D department. He adds: "Our new fibre developments are the basis for
innovative tailor-made solutions for the individual requirements of our customers and we are looking forward to interesting and productive conversations when
we present these novelties for the first time at the IDEA."
With these new fibres Kelheim Fibres extends its already wide range of viscose specialities and puts once again a strong focus on papers and nonwovens.
We are the only European manufacturer of viscose short cut fibres and see a huge potential in supplying fibres for speciality papers. The markets for tea bags,
coffee pads or any kind of filters are growing rapidly, as are the production capacities of the relevant paper producers. At the same time we can offer fibres
with yet more functionality and so broaden the range of potential applications- I'm expecting fascinating developments" says Matthew North, Commercial Director
of Kelheim Fibres.
Kelheim supplies short cut from 0.75dtex to 9dtex with cut lengths from 4mm to12mm and is therefore able to fulfil the needs of very different customers and
very different production processes.
Different fibre cross sections, a wide range of fibre properties and dry short cut for the airlaid industry broaden Kelheim's range of products even more.
