From the Sector

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

• Testing and development achieve rigidity and safety milestone

Basaltex, pioneers in innovative uses of basalt fibres, has achieved a significant milestone in developing and testing a new composite material solution comprising fibres of basalt combined with EconCore’s patented honeycomb technology.

This new material development has greatly improved fire resistance and is highly rigid, as well as the usual honeycomb properties of light-weighting.

The company has tested the composite of basalt fibres, a bio resin and rPET honeycomb.

Filaments of only stone fibres are extruded at a temperature of 1450°C, similar to glass but with a number of advantages, not least the absence of boric acid in the process.

Combining this ecological fibre with EconCore’s sustainable technology using rPET, and the bioresin polyfurfuryl alcohol - 100% derived from a waste stream of sugar cane - make this a very sustainable and environmentally friendly product, unlike the majority of thermoset solutions in this type of application.

Railway applications require materials with enhanced fire resistance and the testing has shown that the EconCore-Basaltex solution fits these needs well, at the same time offering the perspective of drastic weight reduction against traditional monolithic GRPs used rather widely in train interiors.

Such sandwich panel could be deployed in applications such as cladding panels, partitions, tables and flooring. The thermoset skin layers give a fast cure at elevated temperature, meaning short cycle time and enabling automated production’.

As well as the railway interior application, this new material combination could be used in any application that requires fire performance combined with a low weight.
