Flushable Wipes – Kelheim Fibres Communicates the Solution

Public awareness of the problems caused by moist cleaning wipes disposed of in the toilet is still limited, despite extensive coverage in the press during 2015.

In order to address this issue Kelheim Fibres GmbH has created a brief animated film that focuses attention on the problem of incorrect disposal of such wipes and the solution offered by the company’s Viloft® short cut cellulosic fibre.

“There is still a need to communicate the problems that can be caused by the incorrect disposal of wipes to the consumer, but also that there are solutions available which are engineered to be flushed and that Viloft® fibres made in Kelheim are part of that solution”, says Matthew North, Commercial Director at Kelheim Fibres. “Our new film communicates this message in a simple and effective way for the supply chain and for the consumer”.

Customers using Viloft® fibres to produce flushable products are invited to use the film via links on their own websites and in their promotional material.

Kelheim Fibres can provide more information about their Viloft® short cut fibres at the ITMA Trade Fair in Milan, Italy from November 12 to 19 where the film will also be available to see at their
stand A141b in hall 08.

Danufil® Proshade® - Melange 2.0

Danufil® Proshade® is the name of an innovative new viscose melange yarn resulting from a development cooperation between the three industry partners Kelheim Fibres, Linz Textil and DyStar.

What’s new about Danufil® ProShade®? While usually a melange yarn is spun of differently coloured fibres, Danufil® ProShade® consists of a blend of standard viscose fibres and Kelheim’s speciality viscose fibre Danufil® Deep Dye and is only dyed as needed at a later stage in the process.

This is made possible by the particular properties of Kelheim’s Danufil® Deep Dye fibre: Due to its permanent cationic charge this speciality fibre has a significantly higher dye absorption capacity than standard viscose fibres. The difference in intensity and speed of the dye pick-up of the viscose fibres spun into Danufil® ProShade® allows a wide range of colours in melange dyeing of one and the same fibre material to be achieved.

Thus, Danufil® ProShade® melange yarn offers clear benefits for the dyeing process: a selected range of Levafix® and Remazol® dyes allows a salt-free dyeing process. Due to shorter dyeing cycles it is possible to save up to 30% in terms of water and energy, which is a clear advantage for the environment. At the same time productivity increases –a time saving of up to 40% speaks for itself!

Excellent reproducibility, levelness as well as a high level of light fastness and fastness to washing have been proven in numerous tests and commercial dyeing processes. Furthermore, DyStar offers comprehensive customer support – including support in developing dye recipes that ensure optimum results.

More benefits are obvious in terms of logistics and warehousing: Danufil® ProShade® can replace a stock of differently dyed yarns or fabrics and so reduces significantly the amount of capital required. The subsequent dyeing can be done in thousands of different melange tones according to the customer’s specific needs and so allows a fast and flexible reaction to orders as well as production on demand – even of small melange lots.

Kelheim Fibres‘ expertise in the manufacturing of viscose speciality fibres, know-how and innovative spinning technology from Linz Textil and finally high-quality dyes and customer-oriented support from DyStar are combined in an innovative product which delivers significantly more efficiency and a better ecological performance in melange production.

Danufil® ProShade® is exclusively available from Linz Textil. Danufil® ProShade® is available in all yarn technologies and is a registered brand name of Linz Textil GesmbH. The three partners are currently testing more fibre blends and dyeing possibilities.

Kelheim Fibres and DyStar will be presenting this innovative solution at ITMA in Milan.

Flushable Wipes and Melange Yarns:
Kelheim Fibres to present new products at ITMA

Viscose short cut fibres from Kelheim Fibres have proven to be the perfect raw material for the manufacture of wet wipes which meet the new flushability guidelines issued by INDA / EDANA (GD III) and can be conveniently flushed down the toilet - without clogging the toilet or downstream waste water treatment plants.
During the last few years the wipes producers have been developing a manufacturing process which masters the balancing act between the stability of a wet wipe in use and its disintegration during the flushing process in the toilet. The perfect blend of the raw materials pulp and short cut fibres is essential for the success of this process - in which short cut fibres are responsible for the stability of the wipe.
In practice, VILOFT®nonwoven short cut fibres with their flat cross section have proven particularly successful. They deliver the best performance regarding tailor-made flushability – and score at the same time with their quick and easy processability during the manufacturing process. Here, Kelheim benefits from their long-term experience in manufacturing short cut fibres for wetlaid applications.

As a result, Kelheim Fibres has now been delivering commercial quantities of this speciality fibre for some time.
Kelheim Fibres is the only European manufacturer of viscose short cut fibres, but the Bavarians offer more than just fibres with the ideal properties: Kelheim's viscose specialities consist of 100% cellulose and can therefore be perfectly integrated in all wetlaid processes. After use, the fibres are completely biodegradable. Finally, you have a product which is conveniently disposable via the toilet without the danger of clogging it and which is not harmful to the environment.

Another innovation from Kelheim promises benefits for the environment, too: Danufil® Proshade® is the name of an innovative new viscose melange yarn resulting from a development cooperation between Kelheim Fibres, Linz Textil and DyStar Colours Distribution GmbH. Danufil® Proshade® is a blend of standard viscose fibres and Kelheim’s speciality fibre Danufil® Deep Dye. It is dyed subsequently and then according to the customer’s specific needs. This offers advantages for logistics and warehousing as well as for the dyeing process which can be carried out without the use of salt and deliver savings in terms of water, energy and time.
Curious? The Bavarian fibre experts will be happy to provide more detailed information in Hall 08 at Booth No A141b.

Sustainability and technological innovation:
Kelheim Fibres to present new R&D-results at Dornbirn

Sustainability and health, technological innovation and new functionalities – these are the main topics at the Dornbirn Man-Made Fiber Congress. Kelheim Fibres seizes the opportunity to present the latest findings of their in-house R&D at this industry gathering.

With a total of five lectures the medium-sized viscose speciality manufacturer puts itself in the same league as the industry’s big players – and the broad spectrum of topics is impressive, too:

The Bavarians are engaged in the production of innovative materials consisting of bio-polymers and their tailored functionalization. Dr. Philipp Wimmer will show how the combination of bio-polymers can create new composite materials in which the beneficial properties of all components can equally co-exist and can so enable new applications – as for example in the field of medical products.

Viscose Fibres can be used as a precursor for the production of carbon fibres. At the moment, the main area of application of viscose fibre-based carbon fibres is in high-temperature insulating materials. Dr. Roland Scholz will show how the carbonisation of viscose fibres of different shapes and sizes and with various functionalised additives incorporated in the fibres enables an amplification of possible structures and properties of carbon fibres and gives the potential for new fields of application.

Dr. Ingo Bernt will talk about viscose fibres with inorganic contents, in particular about Kelheim’s flame retardant Danufil® BF fibre. Here, a modified spinning dope ensures an extremely homogenous distribution of the silica-network – and therefore a fibre with very special flame retardant properties, without the necessity to use further FR-additives. Nonwovens made from these alloy fibres do form very stable barrier layers and show a low smoke emission. The production of textile processable fibres with low denier opens further areas of applications. In textiles or nonwovens, a viscose fibre with incorporated IR-reflecting particles can help to reflect the thermal radiation which is released from the human body. The wearer feels the advantage from this thermal retention function as well as from the viscose fibres’ typical properties (e.g. softness). Dr. Daniela Bauer will explain how the intrinsic thermal effect works and which products can benefit from it.

And last but not least, Horst Wörner will present a high performance functional fibre, which has been developed by Kelheim Fibres and their long-standing partner Outlast Technologies. This is a filling fibre for insulation textiles such as bedding articles or outdoor apparel, which – in a combination with other filling materials such as downs – enables an active temperature management by the PCMs incorporated in the fibre.

The whole R&D team of Kelheim Fibres is looking forward to interesting lectures and inspiring discussions at the Dornbirn Man-Made Fiber Congress. You can meet the fibre specialists at Kelheim’s stand in the foyer.

Enhanced Filter Performance thanks to Viscose Speciality Fibres from Kelheim

At the world’s biggest filtration event, the FILTECH conference and exhibition, Dr. Philipp Wimmer from the R&D team of the German viscose speciality fibre manufacturer Kelheim Fibres will present a paper on how beer can be filtered in an environmentally friendly manner by using sustainable viscose speciality fibres and avoiding the use of potentially hazardous diatomite.

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.

The use of viscose speciality fibres from Kelheim is completely safe both for people and for the environment, and this is one of the reasons why the fibres have been used for decades in medical products. The fibres are certified for food contact by ISEGA and the absence of harmful substances in the products is confirmed by their certification to the OEKO-TEX® 100 standard in the most demanding product class. Viscose fibres are taste neutral and are currently used in food and beverage applications, for example in coffee pads and tea bag papers.

Kelheim Fibres’ research team is working on many other possible filtration applications for the use of viscose fibres. As a result of the wide product range Kelheim Fibres offers – from extra high absorbent to water repellent, from flame retardant to ion exchange fibres – there are almost no limits to the imagination. 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.
