From the Sector

Kelheim Fibres is showcasing recent research findings at this year's Cellulose Fibres Conference (13rd-14th of March). The development, led by Dr. Ingo Bernt, Project Leader of Fibre & Application Development at Kelheim Fibres, and Dr. Thomas Harter from Graz University of Technology, provides insights into the correlation between the geometry of viscose fibres and the liquid absorption of tampons.

Kelheim Fibres has long been engaged in the functionalization of viscose fibres, including the specific adaptation of fibre cross-sections. The trilobal Galaxy® serves as an example. The current study underscores the properties of the fibre, primarily rooted in its geometry. This involves taking a closer look at the underlying mechanisms. It has been confirmed that, in contrast to the traditionally round viscose fibres and despite similar chemical compositions and mechanical properties, Galaxy® enables significantly better liquid absorption.

While the higher specific surface area of trilobal fibres already promotes improved liquid absorption, this is not the main factor accounting for the difference in absorption. Instead, the geometric shape of the fibres proves to be crucial. Trilobal fibres create and maintain a more voluminous, extensive network within the absorbent body, providing a larger volume for liquid absorption.

Dr. Ingo Bernt emphasizes, "The results of our study are not limited to tampons—any application requiring increased absorbency can benefit from the properties of our Galaxy® fibres."

The lecture "Geometry Matters: Unveiling Tampon Absorption Mechanisms" by Dr. Ingo Bernt und Dr. Thomas Harter takes place on the 14th of March at 2:50pm.

Not only since 2021 has sustainability been a topic high on society’s agenda. And yet the importance of sustainability for consumers and companies has once again increased sharply as a result of the Corona pandemic, as numerous studies confirm. Then why is it often so difficult to implement this conviction in everyday life? One of the biggest obstacles to sustainable consumer behaviour is the lack of availability of alternatives.

In addition to changing consumer demands, the EU Commission's recent decision on the single-use plastics directive is also prompting many nonwovens manufacturers to look at alternative solutions. Kelheim Fibres is exhibiting at this year's INDEX in Geneva and online with bio-based fibers that offer an alternative to synthetic materials in a wide range of applications. The Bavarians have decades of experience in the nonwovens and hygiene sectors and work on individual customer-specific innovations.

"We want to make it easy for consumers to choose an environmentally friendly option. That’s the case when bio-based solutions offer the same performance as synthetic products," said Matthew North, Commercial Director at Kelheim Fibres." Our fibre technology allows us to create just that: unlike natural fibres, which are available already in fibre form and can only be treated on the surface, we can engineer the properties of our fibres they need for specific applications by specifically intervening in the production process. That way we combine nature - our fibres are made of wood pulp - with performance."

Kelheim's special fibres are made of wood pulp from sustainably managed sources, are produced in Kelheim in an environmentally friendly way and are fully biodegradable at the end of their product life. Kelheim Fibres is the first viscose fibre manufacturer in the world with an EMAS validated Environmental Management System and was awarded a dark green/light green shirt in the most recent Canopy HotButton-Ranking.
