New method for modifying products containing wood fibres developed in Finland

23.01.2008
Potential for new product properties in the biocomposite, paper and packaging industries
VTT Technical Research Centre of Finland has developed a method that opens up new opportunities for the use of lignin-containing wood fibres and other natural fibres as well as fibre products. The method offers an innovative, environmentally friendly approach to customize or even to introduce completely new properties – such as moisture repellency or electric conductivity – to fibre-containing products.

The new chemo-enzymatic modification method of fibre materials enables manufacturers to better tailor the fibre properties according to the desired end product. The method can be used to enhance the original properties or even to introduce new properties to lignin-containing fibre materials. To achieve the desired modification, suitable chemical compounds are attached to the material in a chemical or enzymatic process.

Wood fibre products are moisture absorbent by nature. The new method makes it possible to control the moisture resistance properties of lignin-containing fibre materials even to a degree where they become water-resistant. This opens up new opportunities for the use of wood fibres e.g. in the packaging industry.

Manufacturers in branches of industry such as the biocomposites, building and speciality paper and packaging industries, utilising materials containing lignocellulosic fibres in composite structures, can benefit from VTT’s method for developing various product properties. For example, the process can be used to make antistatic filter papers.

VTT’s chemo-enzymatic method differs from the available chemical modifications in its surface targeted and gentle action. It can also easily be integrated in existing manufacturing and finishing processes of fibres and fibre materials.

”Chemo-enzymatic fibre modification creates new opportunities for the processing of existing fibre products and for manufacturing innovative, tailored fibre products in the paper and packaging process. In the future, tailored wood fibres may present a viable alternative for example to synthetic fibres in various industrial composites,” says Anna Suurnäkki, Senior Research Scientist at VTT.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
