From the Sector

Stahl, a provider of speciality coatings and treatments for flexible substrates, has launched the protective coating Stahl Integra® Dry 725, meeting the increasing demand for water-repellant technical fabrics.  
 
Part of the Stahl Integra® toolbox, Stahl Integra® Dry 725 is a fluorine-free coating for water-repellent technical textiles that harnesses Stahl’s proven polymer technology. Stahl has introduced Stahl Integra® Dry 725 in response to the growing market demand for fluorine-free, water-repellent technical textiles, which is projected to reach USD 605.1 million by 2029.  

Stahl Integra® Dry 725 offers a balanced performance between repellency, durability and adhesion. Stahl's durable water-repellent (DWR) technology, StayDry, repels water from fabric by modifying the surface tension of fibres. The solution can be combined with other top or back coatings and is specifically designed for technical textile applications such as camping equipment or luggage. As a fluorine-free, waterborne coating that is cured at low temperatures, Stahl Integra® Dry 725 can help reduce environmental impact without compromising on quality.

Stahl Integra® is a modular 'toolbox' of tailor-made, customer-orientated protective coating solutions that simultaneously ensure product quality and superior fabric integrity. This means that specific mechanical functionalities – from flame-retardant and breathable coatings to stay-clean technologies – can be introduced at different stages of the production process to meet specific end-market requirements as needed.

Using bio-based and bio-degradable, recyclable insulation textiles to sustainably insulate heat and reduce energy consumption and the carbon footprint - the Aachen-based start-up SA-Dynamics has developed a solution for this dream of many building owners together with industrial partners. SA-Dynamics won the second Innovation Award in the "New Technologies on Sustainability & Recycling" category at the leading textile trade fairs Techtextil and Texprocess for this development.

The bio-based recyclable insulation textiles consist of 100 percent bio-based aerogel-fibres. They contain up to 90 percent air, trapped in the nano-pore system of the aerogel-fibres. The bio-based raw material is sustainably sourced and certified. The insulation textiles made from bio-based aerogel fibres are said to insulate the same or even better than synthetic insulating materials of fossil origin like PET, PE or PP and mineral or stone wool.

"By using bio-based aerogels, we are doing away with fossil-based materials and doing something for the environment and climate," explains Maximilian Mohr, Chief Technical Officer (CTO) at SA-Dynamics. "We are thus meeting the regulatory measures of the EU and the governments of many countries for more climate and environmental protection. By using bio-based, recyclable aerogels, we can revolutionise the world of construction.“

The Aachen-based start-up SA-Dynamics is made up of researchers from the Institut für Textiltechnik (ITA) and the Institute of Industrial Furnace Construction and Heat Engineering (IOB) at RWTH Aachen University.

The bio-based aerogel fibres originate from the LIGHT LINING research project of the BIOTEXFUTURE innovation area. The LIGHT LINING research project focussed on sports and outdoor textiles. The research results are transferable to the construction sector.

The Techtextil and Texprocess Innovation Awards ceremony will take place on 23 April 2024 at 12.30 pm in Hall 9.0 in Frankfurt/Main, Germany.

KARL MAYER has already produced a wide range of electrically conductive warp-knitted items for a wide variety of applications in the TEXTILE-CIRCUIT division of its TEXTILE MAKERSPACE, including a sensor shirt, a gesture control system and a conductive charging station. In order to drive the topic of wearables forward, the textile machine manufacturer has signed a cooperation agreement with the Grabher Group and delivered an MJ 52/1-S to the specialist for high-tech textiles in Lustenau. Managing Director Günter Grabher officially inaugurated the key machine for project work in the smart textiles sector in May 2023.

The machine is involved in various research projects, but is also available for new projects and tasks. The smart textiles competence team at KARL MAYER and Grabher is looking forward to supporting the ideas and work of interested parties also outside the research network with its know-how and the possibilities of the MJ 52/1-S.

The MJ 52/1 S is also an extremely flexible project machine. The 138″ model in gauge E 28 produces a wide range of warp-knitted fabrics and incorporates conductive material directly into the textile surface - exactly where it is needed and with the structure that is required. The basis for the tailor-made fiber placement is KARL MAYER's string bar technology. The system for controlling the pattern guide bars ensures a fast, established textile production process and a high degree of pattern freedom.

“From Earth to Earth”: The new plan defines goals and concrete actions in Environmental, Social and Governance (ESG) areas to foster value creation for all stakeholders and put new sustainability regulatory requirements at the centre of attention.

A project, designed to enhance RadiciGroup's transparency and commitment to develop a responsible business along its entire value chain from an economic, social and environmental perspective and focus on the ever more widespread and stringent sustainability regulatory requirements. These are the features and goals of the Sustainability Plan presented by the Group and called "From Earth to Earth", precisely to emphasize the intent to focus on the Earth and future generations.

In the context of a complex and constantly changing scenario, the Group has therefore decided to capitalize on the goals achieved and look beyond them with a plan defining the medium-term targets and the actions to be taken to fulfil them and covering all areas considered to be "material”, i.e., relevant from the point of view of ESG and financial risks, opportunities and impacts. Indeed, the ultimate goal of "From Earth to Earth" is to support business continuity and the growth of the company and all its stakeholders.

The project was the result of a multi-year collaboration with Deloitte, which contributed an external and objective viewpoint on the definition of the material targets and themes. However, it was not an armchair exercise, but the result of an extensive listening process involving internal and external stakeholders, all of whom were sustainability experts who helped define a shortlist of strategic themes for both the Group and its main stakeholders. These issues were then analysed in detail using working tables on the different themes to identify the objectives in Environmental, Social and Governance areas and the related concrete actions needed to achieve them, in line with the European decarbonization and energy transition policies and the
United Nations Sustainable Development Goals, a global blueprint for sustainable growth.

In particular, RadiciGroup’s environmental goals include: a 20% increase and differentiation in renewable source electricity consumption, an 80% reduction in total direct greenhouse gas emissions by 2030 compared to 2011, attention to water consumption to limit the impact on local communities and biodiversity, the extension of Life Cycle Assessment (LCA) methodology to measure the environmental impact of 70% of the products (in terms of weight) manufactured by the entire Group, collaboration among the various actors in the supply chain from an ecodesign perspective and the search for increasingly more sustainable and circular packaging solutions.

The Dutch company Knitwear Lab helps visions become reality. The creative think tank offers capacities in the areas of R&D, design, knitwear development and production of prototypes and small quantities and has thus implemented a wide range of projects in recent years. The objects range from medical products and high-tech sportswear to smart textiles with integrated sensors. Sustainability activities are also part of the repertoire, such as the production of yarns from recycled waste.

Knitwear Lab operates at two locations for its diverse tasks: Almere in the Netherlandsis available for development work. In Istanbul, there is a branch for production. Both Knitwear Lab sites each have five STOLL flat knitting machines, including models from the modern ADF range. Prototypes are produced in Almere and there is small-scale production. The production plant in Istanbul specializes in the manufacture of high-quality knitwear in small quantities. STOLL is also involved in the creative processes. For the industrial development of knitwear, Knitwear Lab offers Virtual Knitting, a revolutionary method that combines virtual and physical elements of pattern development and knitwear production to reduce waste and pre-production steps. Customers can use Virtual Knitting to create realistic, producible collections, simplify their design iteration processes and take advantage of the wide range of real-life colorways. The basis for this is comprehensive knitwear expertise, the latest 3D software and the CREATE PLUS patterning software, which was developed by STOLL together with KM.ON.

"The 3D visualization of CREATE simplifies communication with the customer considerably. We use this function every day," says Annika Klaas, Senior Knitwear Programmer. She personally appreciates the uncomplicated grading and exchange of stitch dimensions and the much faster and more efficient work with Dimensioned Shapes that this makes possible. This helps her in her day-to-day work. "We often have requests to realize the same product in different yarns, which now works much faster," says the programmer. Further simplifications would include minor optimizations in terms of the efficiency and user-friendliness of programming and additional import and export options for shapes. Discussions on implementation are already underway.

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.

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.

From mechanical engineering to the construction industry, from logistics to rescue technology – tensioning and clamping systems fulfil important tasks in a number of industries. The possible uses of technical textiles for industrial applications of this kind are manifold.

Patented and precisely configured
The ElasTool system from the elastics expert consists of a connection tool and a rubber rope connected to this tool via integrated locking elements. The stainless steel, aluminium or plastic connection tool and the rubber rope – with a thickness of between 12 and 38 mm – are each configured to fit precisely. The highlight of the patented connection solution: the more tensile force is exerted, the more the rope is jammed. Thanks to the locking system, ElasTool still provides a secure hold even when the diameter of the rubber rope narrows to up to 60 percent due to the tensile load. A crucial advantage over conventional end connections by pressing.

Economical and low maintenance
The system has further advantages: the textile solution runs quietly. Unlike clamping systems with steel cable springs, there is no creaking here. In addition, textiles, plastic and aluminium are particularly lightweight materials. ElasTool therefore saves energy. Another benefit: the connection system works without lubricating oil. While conventional tensioning and clamping solutions in industrial plants and products have to be oiled regularly, the JUMBO textile system works completely maintenance-free.

Versatile and easily interchangeable
Depending on the area of application of the ElasTool, the interchangeable head can be exchanged: Plastic hook instead of aluminium eyelet, stainless steel flange instead of aluminium hook – for example. The interchangeable head can be replaced effortlessly and without special tools.

"A lifting system in a high-bay warehouse, a trolley in a crane, damping for compressors or crash systems – these are just three of the many possible applications. We adapt the dimensions, material, force-stretch behaviour, flame retardancy – like all properties – specifically to the respective project," emphasises Carl Mrusek, Chief Sales Officer of JUMBO-Textil. "Thus, with ElasTool, we offer a safe load connection for a wide variety of applications in industry."

Viscose speciality fibre manufacturer Kelheim Fibres, nonwoven producer Sandler, and hygiene product manufacturer pelzGROUP have jointly developed a new panty liner that is plastic-free according to the European Single-Use Plastics Directive (SUPD). This innovative solution is a step towards reducing the amount of plastic in hygiene products – and thus also a contribution to tackling the problem of plastic pollution.

According to a UNEP study on marine litter and microplastics, eight million tons of plastic end up in the oceans every year. A significant portion of this pollution comes from single-use plastic products, including conventional period products such as pads or panty liners.

The partnership between the three companies was formed under the Open Innovation principle, which allowed for creative idea exchange and facilitated the development of an innovative product. According to Jessica Zeitler, R&D Specialist at Sandler, “Our collaboration with Kelheim Fibres and pelzGROUP is a great example of how companies can work together to create solutions that benefit both the environment and consumers. We are proud to be part of this project and the opportunities it offers.”

For hygiene product manufacturer pelzGROUP, it is important to combine sustainability and performance to achieve broad acceptance in the market. “Our panty liner meets the strict requirements of the European Single-Use Plastics Directive (SUPD) while also matching the performance of conventional synthetic products. At the same time, our new panty liner has a completely European supply chain. This means short distances and therefore low CO2 emissions, and – especially in times of global disruption – reliability for our customers,” emphasizes Dr. Henning Röttger, Head of Business Development at pelzGROUP.

"Our viscose speciality fibres are an environmentally friendly and high-performance alternative to synthetic materials," says Dominik Mayer, Project Manager Fibre & Application Development at Kelheim Fibres. "They are at the very beginning of the product value chain and yet have an enormous impact on the functionality of the end product. Open innovation allows us to bring all partners in the value chain to the table, to find the best solution together in a very short time and bring it to commercialisation - the collaboration with Sandler and pelzGROUP is an important milestone in our AHP journey."
