DITF: Lignin coating for Geotextiles

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

Their vision for the B.I.G. change is to actively build a better future by their our carbon footprint to zero and doing business in a transparent, integer way. In this sense, it is the translation of the Group's purpose defined in 2021: shaping sustainable living, together.

Pol Deturck adds “By 2030, together with a broad group of suppliers, stakeholders and partners, we want to be the leader in sustainable flooring and material solutions. Specifically, our future value proposition is based on products and services that are environmentally & climate friendly, circular and offered by talented, innovative people with an emphasis on integrity and respect for values. This results more in a recurring value proposition for the future.”

Clear growth ambitions
As a 100% family-owned international Group with a clear long-term vision, B.I.G. stayed true to their plans and kept on investing in all areas of their business.
“The ambition for 2021 was to invest over 100 mio euro. But we were held back by external, unforeseen factors: from delays on quotes and execution to the lack of availability and resources due to the pandemic. If all goes as planned, we’ll make up for it in 2022 with an investment budget well over 100 million euro. The main areas of interest will be sustainability, innovation and Industry 4.0.” says Pieter-Jan Sonck, CFO of B.I.G.

Adding to the gradual top-line growth of recent years, the Group can look back on an unprecedented financial boom. The driving forces: favorable market conditions, a revitalized growth strategy and a team of nearly 5.000 first-class employees.

B.I.G. reported a turnover of EUR 2,5 billion, an increase of 45 % compared to 2020. The Group ebitda amounted to EUR 451 million, an increase of 120 % compared to 2020 and a net result of EUR 274 million, a growth of 215% compared to 2020.

Fruitful year for all Business Units
It was a fruitful year for all 3 business units, but the Group's business unit Polymers stood out. Exceptionally strong demand in Europe and North America, combined with raw material shortages and unplanned shutdowns of competitors, pushed prices and margins up to highs. The Polymers facilities ran at full capacity to meet the customers’ needs and hit all-time profit records during several months.

The Group's business unit Flooring Solutions also fared well. Most divisions and regions outperformed amid surging energy prices, disrupted supply chains, cost volatility in transport and raw materials, and other challenges. Their sustained focus on innovation, design and product differentiation led to an improved operating result at the end of 2021.

The achievements by Engineered Solutions echo those of the other two business units, from volume increases to budget increases. B.I.G. took big leaps forward in all its key markets, including the automotive sector, geotextiles and filtration.

  • Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

TMAS: TEXO AB sees Demand for Compfelt Weaving Looms

TEXO AB, a member of TMAS, the Swedish textile machinery association, is currently seeing a surge in demand for its Compfelt weaving looms for press felt base fabrics.

“These are far from standard machines,” explains TEXO President Anders Svensson. “Off-the-shelf industrial weaving machines generally range in their working widths from 1.9 to 3.2 metres, with those purpose-built for technical applications such as geotextiles extending to wider widths of six metres and beyond. Meanwhile, one of the machines we have recently successfully delivered and commissioned has a working width of 23 metres and is not even the widest of the many such machines the company has engineered and delivered worldwide since its formation.”

A second recently-delivered line has a more modest working width – in relative terms – of 13 metres.

Meanwhile, one of the machines we have recently successfully delivered and commissioned has a working width of 23 metres and is not even the widest of the many such machines the company has engineered and delivered worldwide since its formation.”

A second recently-delivered line has a more modest working width – in relative terms – of 13 metres.

Paper machines
The demand for such machines comes from the suppliers of paper machine clothing (PMC) to paper mills, who in turn operate colossal machines for paper manufacturing.
On of the largest paper making machines is currently believed to be located on Hainan Island off the southern coast of China and is 428 metres long – roughly the length of four football pitches. Naturally, such machines require equally large-scale components, which is where TEXO comes in. All paper machines require a regular supply of PMC fabrics which are employed in three separate areas of the paper machine – the forming section, the press section and the drying section.

Press felts
TEXO Compfelt weaving machines are specifically employed for the production of endless (tubular) woven base fabrics for the press section of paper machines, where water is mechanically removed from the newly formed sheet of fibres. In the simplest press, the sheet is carried by the PMC fabric between two rolls, where water is squeezed out by the application of load and pressure. This can also be assisted by the use of vacuum and heat. The PMC fabrics here need to be replaced regularly, with a maximum lifespan of six months.

Press felts have become increasingly sophisticated over the years, consisting of complex woven base structures which are subsequently combined with nonwovens via needlepunching on equally huge machines. The woven base fabrics are primarily made from polyamide for its strength and hygroscopic and elastic properties.

Dobby harness
“A major refinement of the machine has been the ability to equip it with up to 24 dobby harness frames to meet the demand for sophisticated structures from the PMC manufacturers. Although the PMC business represents a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.”

Another significant development has been that of a self supporting base pre-filled with concrete, which has eliminated the need to dig out foundations in a plant to support the machine.

Retrofits
TEXO’s looms are built to last, but technology moves forward, and the company is also currently active in the retrofitting of existing machines built as far back as the 1970s.

Integration
TEXO has also just integrated its offices and production centre at its base in Älmhult, Sweden, to create a unified 5,000 square metre site.
