From the Sector

Beaulieu International Group will turn the spotlight on geotextile products with sustainability benefits to support progress in resilient civil engineering projects at the 12^th ICG Rome from 18^th -21^st September 2023, presenting options to target fossil carbon reduction by choosing PP-based staple fibres or woven geotextiles that are among the lowest in carbon footprint for geosynthetics.

For manufacturers of nonwoven geotextiles, Beaulieu Fibres International (BFI) offers PP fibres with > 25% carbon footprint reduction compared to the European standard PP fibres, generating 1.48 kg CO₂/kg PP fibres. A step further is to accelerate the replacement of fossil carbon in engineered fibre applications by choosing its ISCC Plus certified bio-attributed MONO-PP with a negative carbon footprint.

For construction projects, nonwoven geotextiles made with high-tenacity HT8 fibres are proven to secure a longer service lifetime and reduce the environmental impact, as they offer high mechanical performance at a reduced weight.

Beaulieu Technical Textiles' (BTT) woven geotextiles provide a wide range of functions, including separation, filtration, reinforcement and erosion control, and are among the most sustainable in the industry. Depending on weight, the carbon footprint of its woven geotextiles (m²) ranges between 0.37 and 1.40 kg CO₂ eq./m². They also minimize the use of natural resources for more sustainable infrastructure development. Case studies such as at the Ostend-Bruges airport highlight significant CO2 reduction on the jobsite by replacing the transport of 960 trucks of gravel with 3 trucks of woven geotextiles, and by extending the runway’s life span.

The ICG launch of its new line Terralys MF woven filtration geotextiles with monofilament boosts the performance of a common solution in building layers that require high water flow rates. High-tenacity extruded polypropylene tapes and monofilaments are interwoven to form dimensionally stable and highly permeable geotextiles. These new filtration geotextiles provide greater resistance to dirt and biological clogging. They allow water to travel freely while reducing soil erosion when employed as a separation and stabilizing layer.

As of September 2023, all PP staple fibres and woven geotextiles will have Environmental Product Declarations (EPD) based on LCAs. Each EPD is an essential tool for communicating and reporting on the sustainability performance and helps carbon-conscious customers in their purchasing and decision making. Registered EPDs are globally recognized, publicly available and free to download through EPD Libraries.

Spinnova has decided to evaluate its existing strategy to prioritise areas that in the short- to medium-term deliver the fastest time to positive cashflow generation and that create the most value for the company’s stakeholders.
 

The company expects to conclude the assessment of its strategy in the coming months, after which the results will be presented in more detail including key actions and any changes to medium- and long-term business targets. Financial guidance for full year 2023 is unchanged.

Spinnova’s unique sustainable technology is a key differentiator. To recognize the value of its technology offering, the company has decided to review opportunities to expand the licensing of its technology to new customers. In the future, Spinnova sees great potential in developing circular raw materials such as textile waste and agricultural waste, as well as recycled SPINNOVA® fibre. Initial tests show that refining these raw materials into micro fibrillated cellulose (MFC) may be more efficient than refining other raw materials Spinnova has worked with. The company has received significant interest from customers wanting to build plants that convert multiple circular raw materials into SPINNOVA® fibre.

Together with Suzano, Spinnova is gathering the learnings from the first Woodspin plant to support the decision making for the next Woodspin factory investment. At the same time Spinnova continues to further develop the technology concept to reduce capital expenditure per tonne of fibre produced compared to the first Woodspin plant. While Suzano develops its MFC process it is expected that the first Woodspin facility will mainly be used for R&D to test new MFC batches and that commercial production volumes will be limited in the short term. The market opportunity and ambition level with Suzano to scale Woodspin’s production capacity remains unchanged

Spinnova will continue to have the option to invest into all future Woodspin and Respin plants, as per the respective joint venture agreements. The company will evaluate whether it participates in these investments based on the value it creates for Spinnova’s shareholders compared to other opportunities to invest Spinnova’s capital. Regardless of whether Spinnova invests its own capital into future plants, Spinnova will continue to be the exclusive technology provider to Woodspin and Respin, and they will continue to be important technology customers of Spinnova.

The Lenzing Group, a leading provider of specialty fibers for the textile and nonwoven industries, has made significant technical improvements to its Purwakarta site (PT. South Pacific Viscose). Lenzing has invested more than EUR 100 million since 2021 to convert existing production capacity to specialty viscose. With the imminent completion of the investment, Lenzing is in a better position to serve the strongly growing demand for specialty fibers.

Lenzing is striving for certification according to the standard of the internationally recognized EU Ecolabel1. The product portfolio would thus include LENZING™ ECOVERO™ branded fibers for textiles and VEOCEL™ branded fibers for nonwoven applications. In the course of these substantial investments, Lenzing has set the goal of significantly reducing emissions at the site. Moreover, the site started to obtain renewable grid electricity and promotes a changeover to biomass in line with Lenzing's goals of reducing carbon emissions per ton of product by 50 percent by 2030 and achieving carbon-neutral production by 2050.

“Demand for specialty fibers with low environmental impacts continues to grow structurally. We see enormous growth potential in Asia in particular. Through our investments in Indonesia and also at other Lenzing sites worldwide, we are in a better position to serve this growing demand. At the same time, we continue working tirelessly to make the industries in which we operate even more sustainable and to drive the transformation of the textile business model from linear to circular,” says Stephan Sielaff, Chief Executive Officer of the Lenzing Group.

Biella Yarn’s new Fall/Winter 24/25 collection presents two collaborations. Both collaborations start with one common inspiration: with the clash of different cultures and the distant exotic markets. Rug making, fur-crafts and artisan hand work inspire patterns and textures which are translated into knitted fabrications and 3D designs.

MRC Knitwear Research Lab created these textures and patterns by using a small selection of very classic yarns and working them in special techniques to create rich textural fabrications. Each garment focuses on a special technique and combination of yarns and colours and show how versatile a single yarn can be.

The garments were knitted mainly with Victoria Nm 2/30 (100% Merino wool extrafine, 19.5 μ, anti-shrinkage). Victoria Nm 2/30 was used in an array of different techniques and on different gauges - from 14gg ribs, that have a beautiful drape to more tactile fabrics such as 3-dimensional stitches on 12gg and heavily patterned inlay jacquards on the 14gg Shima Seiki SRY. Within these inlay jacquard’s BaltoroPro Nm 2/28 (70% Merino wool extrafine, 19.5 μ, anti-shrinkage 30% Polyester GRS High Bulk) was selected as an inlay yarn - a special wool blend which helps create bulky 3-dimensional fabrications that remain lightweight. The classic Brisbane Nm 2/60 (100% Merino wool Superfine, 17.5 μ, anti-shrinkage) and new boucle yarn Fluffy Nm 14 000 (81% Merino wool extrafine, 19.5 μ, anti-shrinkage, 19% Polyamide) were worked together in fine plush jacquards to give an effect of shaved patchwork furs.

The structures and patterns were transitioned into the world of 3D designs by Shima Seiki Italia. The design software APEXFiz®, developed by Shima Seiki, not only allows for shaping but also converts them into knitted patterns. By replacing physical samples, virtual samples reduce time costs, and materials that would otherwise be wasted. Yarnbank®, Shima Seiki's platform for yarn and spinning research, has been the primary source of Suedwolle Group's digitized yarns used in the 3D models.

The KARL MAYER GROUP and the Südwolle Group have joined forces in a project to explore the possibilities of merino wool for warp knitting technology. The project was triggered by the increasing demand for textiles made from sustainable and environmentally friendly materials. The cooperation was to develop innovative fabrics from renewable raw materials for use in underwear and functional sportswear. The focus of the work was on the use of wool as a material with excellent comfort properties and the look and feel of lightweight single jersey goods. The natural fiber fabric qualities are not typical for warp knitting processing, so the challenges during the project work were diverse.

Merino wool yarns with good running properties
Regarding the choice of material, the product development team of Südwolle Group recommended the Hidalgo yarn from their product portfolio. The yarn was created using the in-house developed Betaspun technology, in which a filament was twisted around a merino core. When natural fibres such as wool, cotton or silk are combined with sustainable fibres such as biodegradable polyamide as the filament, the spinning process can create durable, lightweight yarns that disintegrate completely without residue after use. The yarns made from the two components also have good running properties for use in warp knitting. "The polyamide content of the yarn increases its tenacity, reduces hairiness and makes it an excellent choice for warp knitting technology," confirmed Gabriela Schellner from KARL MAYER's Textile Product Development Department.

Shape stability paired with single jersey "look and feel"
The Hidalgo yarn, which is made from merino wool, was processed on a warp knitting machine using a carefully thought-out lapping selection to produce a light, soft fabric which, above all, retains its shape. The textile specialists at KARL MAYER had experimented with two different single bar fabric qualities beforehand and had thus adopted a new approach for jersey machines.

The first results are promising. Now more trials are needed to perfect the technique. Development partners are needed, including fabric producers, brands, and garment manufacturers, with whom the fabric qualities, machine equipment and orientation to the end applications can be refined. The KARL MAYER GROUP and the Südwolle Group are also unanimous in their desire to push the boundaries of what is possible with merino wool and knitting technology and to develop new solutions for the textile industry through further project work.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.
