Man-made fiber yarns with DNA: Supply chains in textile end products traceable

In cooperation with the Swiss company Haelixa, Oerlikon Manmade Fibers Solutions will, in future, be able to make the entire value chain of a textile end product transparent and hence sustainable. The two development partners are offering a solution for the comprehensive traceability of products, as required by the European Green Deal.

An essential part of the solution is the DNA marker technology developed by Haelixa that enables complete traceability of materials. These markers survive all production process steps, validating that the end product is identifiable. "This innovative technology employs distinct DNA tailored for each project, establishing a unique identity for the material," explains Holly Berger, Marketing Director at Haelixa. "Once the DNA is integrated into the material, it becomes irremovable, impervious to falsification or alteration." Handling is straightforward: the DNA marker is fed into the spinning process with the preparation oil, for example. The preparation system is modified accordingly. Further feeding options are currently being developed.

Smart factory: total transparency with atmos.io
The concept is complemented by atmos.io, Oerlikon's digital platform, which records and evaluates extensive production and process data during the yarn manufacturing process. Atmos.io gives the yarn its digital identity during its time on Oerlikon systems, from the melt to the packaged package. This technology has been used successfully for some time to monitor the production process. With atmos.io, deviations in process parameters and yarn data can be identified and rectified within a very short time, which in turn keeps the yarn quality stable and reduces waste rates.

Combining both technologies enables clear traceability of the yarn produced, even in the downstream process steps. Hence, the yarn's components, qualities, manufacturing conditions, and origin are traced beyond doubt in the finished garment. "The unique DNA carries the 'roots' of the yarn digitally recorded in atmos.io into the everyday life of the end consumer," says Jochen Adler, CTO at Oerlikon Manmade Fibers. The textile end products meet the requirements of the digital product passport required by the EU, which contains the information needed to assess their life cycle assessment and circularity. Initial long-term tests have shown 100% traceability of the yarns in the POY and FDY spinning process. If the yarn manufacturer relies on the atmos.io platform, production systems can be adapted relatively easily to use the DNA markers.

Carbios’ solution offers brands an alternative to petro-sourced plastic that helps them meet their sustainability commitments. This advancement paves the way for future applications in other sectors such as packaging, food and beverage, and textiles.

Carbios and L’Oréal: a long-term collaboration
Since 2017, Carbios and L’Oréal have been working together with a shared vision of accelerating the transition to a circular economy for plastic. In 2017, both companies created a Consortium to improve the recyclability and circularity of PET packaging.  Nestlé Waters, PepsiCo and Suntory Beverage & Food Europe joined this Consortium in 2019 to scale up Carbios’ innovation. The world’s first enzymatically recycled PET packaging was made in 2021 using Carbios’ biorecycling process. The world’s first PET biorecycling plant is scheduled to be commissioned in 2025. In parallel, Carbios is rolling out its technology internationally through licensing agreements.

The environmental benefits of biorecycling developed by Carbios
Recent life-cycle analyses[1] show a 57% reduction in CO2 emissions compared with the production of virgin plastic[2], and for every tonne of recycled PET produced, 1.3 tonnes of petrol are avoided. Compared with conventional recycling, enzymatic recycling is 4 times more circular (calculated according to the Ellen MacArthur Foundation’s Material Circularity Indicator). Thanks to its highly selective enzyme, optimized for efficient PET degradation, Carbios’ depolymerization process can process all types of PET waste, including colored, multilayer or textile waste that cannot be recycled using current technologies. Furthermore, the two monomers produced (PTA and MEG) make it possible to recreate recycled PET products of identical quality to virgin ones, and suitable for food contact.

HeiQ AeoniQ™ joins Canopy and commits to Forests Protection

HeiQ AeoniQ™ becomes an active brand partner of the Canopy initiative with eleven other companies to address the growing climate and biodiversity crises by committing to keep Ancient and Endangered Forests out of our man-made cellulosic fiber supply chain.

The commitments that HeiQ AeoniQ™ is making are part of solutions-driven non-profit Canopy’s Pack4Good and CanopyStyle initiatives which currently represent collectively 950 brand partners. Together, the initiatives are shifting supply chains away from vital forests to low-impact, circular Next Gen Solutions.

HeiQ AeoniQ™ becomes an active brand partner of the Canopy initiative with eleven other companies to address the growing climate and biodiversity crises by committing to keep Ancient and Endangered Forests out of our man-made cellulosic fiber supply chain.

The commitments that HeiQ AeoniQ™ is making are part of solutions-driven non-profit Canopy’s Pack4Good and CanopyStyle initiatives which currently represent collectively 950 brand partners. Together, the initiatives are shifting supply chains away from vital forests to low-impact, circular Next Gen Solutions.

“We must rapidly replace oil-based polyester in the textile industry causing microplastics, global warming, landfill and ecosystem degradation. Cellulose is the most abundant biopolymer in the world and is best suited to replace polyester. However, we must pay attention to cellulose feedstock sources. Our forests, a potential cellulose feedstock, are one of the most important solutions to addressing the effects of climate change. Approximately 2.6 billion tons of carbon dioxide, one-third of the CO2 released from burning fossil fuels, is absorbed by forests every year. Around 12.5% of global greenhouse gas emissions (5-10 GtCO2e annually) come from deforestation. We are losing forests at an alarming rate. Every year, around 10 million hectares of forests globally are destroyed. We need immediate action to increase forests again. Canopy is our go-to partner to replace polyester with circular & sustainable cellulose feedstock for our innovative HeiQ AeoniQ™ fiber revolution.” said Carlo Centonze, HeiQ Group CEO.

Paper packaging is also a key driver of forest loss globally, as 3.1 billion trees are cut down annually to produce the boxes and bags in which products are packaged and shipped. Paper packaging production has increased by 65% over the past two years.

“The range of companies and sectors represented in today’s announcement reflects the breadth of market response to the growing climate and biodiversity crises and intensifying supply chain disruptions,” said Nicole Rycroft, Founder and Executive Director of Canopy. “Today’s brand partners add significant momentum to global conservation efforts and the movement to transform ‘take, make, waste’ supply chains to be lower-impact and Next Gen.”

Today, as part of Pack4Good, HeiQ AeoniQ™ committed to:

  • Eliminate Ancient and Endangered Forests from our paper packaging supply chain.
  • Reduce material use through design innovation.
  • Maximize recycled content.
  • Explore and scale alternative Next Gen fibers (such as agricultural residues).
  • Where virgin fiber is necessary, use FSC-certified fiber.

Lenzing relies on wind power in the fiber and pulp production

The Lenzing Group has concluded a supply contract with the Austrian electricity producer WLK energy for the purchase of around 13 megawatts of wind power. Lenzing is thus not only underlining its commitment to climate protection and the energy transition, but is also making a long-term investment in a price-stable and diversified electricity supply. The contract has a term of 15 years and provides for supply from the new wind farm in Engelhartstetten from the first quarter of 2025.

The construction of the wind farm is a joint project involving several partners, including the operator and electricity supplier WLK energy, based in Untersiebenbrunn (Lower Austria). The total output of the wind farm with a total of eleven wind turbines will be around 45 megawatts. The share of around 13 megawatts, which will be produced exclusively for the needs of the Lenzing site (Upper Austria), corresponds to the average electricity requirements of around 10,000 households per year in Austria. The ground-breaking ceremony to mark the start of construction took place on November 09, 2023 with representatives from politics and business.

ECHA: Toxic chemicals in childcare products

The European Chemicals Agency (ECHA) has found that substances causing cancer, genetic mutations or harming reproduction are present in childcare products, such as car seats, bibs and baby changing mats. Its investigation will help the European Commission to prepare an EU-wide restriction to limit these chemicals, with the aim of safeguarding children.

ECHA’s investigation, drawing on information from 48 different sources, shows that substances which are carcinogenic, mutagenic or toxic for reproduction (CMR) may be present in childcare products (articles). Metals like cobalt and lead, along with phthalates like DEHP, are the most common CMR substances found in childcare products.

CMRs were most often found in items like car seats, bibs, products related to toiletries, and bedding and mattresses. Children may be exposed to these hazardous substances during use, for example through skin or oral contact, and are particularly vulnerable to the harm caused by chemical substances because of their small size, developing physiology and behaviour.

Children may be exposed to these hazardous substances during use, for example through skin or oral contact, and are particularly vulnerable to the harm caused by chemical substances because of their small size, developing physiology and behaviour.

ECHA’s report provides elements to support the European Commission in the preparation of a potential future restriction. These include information on how childcare articles are defined, what the restriction could cover, potential derogations, recommended concentration limits and timeframes for implementation. The report also includes views from ECHA’s Enforcement Forum on how feasible it would be to enforce such a restriction.

The report will now be sent to the European Commission, who will use it to prepare a draft restriction proposal under REACH Article 68(2). This procedure allows the Commission to prepare a restriction proposal without involvement of ECHA’s scientific committees.

Background
The purpose of ECHA’s investigation is to support the European Commission in preparing a restriction under the REACH Regulation to protect children from exposure to CMR substances in childcare articles. It focused on substances that have a harmonised classification under the Classification, Labelling and Packaging (CLP) Regulation as a CMR in category 1A (known human carcinogen, mutagen or reproductive toxicant) or 1B (presumed human carcinogen, mutagen or reproductive toxicant).

During the investigation, ECHA organised two public calls for evidence and a consultation on the draft report. The Agency contacted 233 different stakeholders to inform about the work and considered their feedback.

Italian textile machinery: Drop in orders intake in third quarter 2023

The textile machinery orders index, as processed by the Economics Department of ACIMIT, the Association of Italian Textile Machinery Manufacturers, dropped fully 20% during the third quarter of 2023, compared to the same period for July to September 2022. In absolute terms, the index stood at 84.2 points (basis: 2015=100).

This result is due to a reduction in new orders recorded by manufacturers both on the domestic market and abroad. The decrease in orders in Italy came in at 45%, whereas the drop was just 13% on foreign markets. The absolutevalue of the index abroad stood at 80.5 points, and 119.4 points in Italy. During the year’s third quarter, new orders reached 3.7 months of assured production.

During the year’s third quarter, new orders reached 3.7 months of assured production.

ACIMIT President Marco Salvadè commented on the data, stating that, “The order index for the period from July to September 2023 confirms a contraction in collected orders that was already evident in previous quarters. What worries us above all is the situation with our domestic market, where the declining trend has persisted for seven consecutive terms. Due to this situation, which does not only concern the textile machinery industry, urgent measures are needed from Italian Government to strengthen the competitiveness of Italian manufacturers.”

As far as foreign markets are concerned, the orders index confirms an overall weakened global demand for textile machinery. Indeed, for the first half of 2023, Italian exports slowed in a variety of essential benchmark markets, such as Turkey, China and the United States.

“The global economic scenario remains negative, as consumers are facing a reduced purchasing power, with investments in the textile sector consequently also slowing down,” concludes Salvadè. “In less than a month, ITMA ASIA + CITME will be held from 19 to 23 November in Shanghai, primed as one of the world’s major trade fairs for the textile machinery industry, with the participation of roughly 60 Italian textile machinery manufacturers. We can expect some significant indications on the industry’s state from this event, which will be staged in one of the strategic markets for textile machinery demand.”

Mahlo presents new solutions at ITMA Asia 2023

Mahlo GmbH + Co. KG will present its systems and solutions for efficient and high-quality textile production and finishing together with Shanghai Kuantex at ITMA Asia (November 19 and 23). The focus will be on the machine manufacturer's new straightening concept, the Orthopac RXVMC.

"In the new straightening concept, special attention was paid to the straightening mechanics and their interaction with the analysis electronics of the probe system," explains Sales Manager Thomas Höpfl. The control concept is also new. A probe group at the leveler infeed detects distortions even before they reach the correction rolls. In this way, the rolls are brought directly into position and the fabric is corrected from the very first centimeter. A scanner group at the outfeed also detects possible residual distortion, which is corrected at the second straightening module. This enables an even more precise and faster response when it comes to reacting to rapidly changing distortions. The Orthopac RXVMC therefore shows its full strength when straightening knitwear and fabrics sensitive to distortion.

Also contributing to high-quality textile production and finishing is the Famacont PMC for controlling weft and stitch course density, which will also be on show at ITMA Asia. The Famacont PMC-15 uses a sensor to measure the yarn or stitch density and compares it with the target value stored in the recipe data management system. The detected deviation of the yarn density from the target value is used to fully automatically regulate the leading during the needling process on the stenter frame. Interested parties can have the mode of operation explained to them at the Mahlo booth with the help of a demo tower and their own or provided fabric samples.

Another major topic remains Industry 4.0, because the best measured data is of no use if it cannot be utilized. Mahlo has continuously developed its digital environment mSmart. "Our systems generate data that the customer can use immediately to regulate goods on-line. At the same time, all measured values are backed up in our data management system mLog enhanced and can be retrieved at any time. With this historical data, processes can be optimized and weak points in the process can be minimized," explains Sales Manager Thomas Höpfl.

Market proximity
Swiss companies realized many years ago that geographical proximity is the key to success. Stäubli has started to set up offices in Chinese cities since 1998 and counts 12 locations today, to serve the whole country. In 2002, Itema established a centralized local branch which today has 160 employees in various functions. Loepfe has expanded its presence by creating an independent local business unit to overcome the 9,000 km distance by air, while Uster Technologies has had a Chinese subsidiary since 1982, with offices and service stations in different provinces. Luwa set up its offices and workshop in Shanghai in 1997. Rieter established a presence in mainland China in 2005, driven by a strong commitment to expanding the country’s know-how and expertise – and ten years later opened an advanced research center. All Swiss companies with serious business goals in China have made similar commitments to connect with customers and maintain strong relationships.

Understanding Chinese customers
Swiss companies also understand that Chinese customers require dedicated attention, and that speed is more essential than ever in delivering both machines and services.
Manufacturers in China are seeking cost-effective solutions to remain competitive, while consumers are looking for value in their purchases. Companies need to develop solutions that provide tangible economic benefits to their clients. Furthermore, energy savings have become paramount in China, due to the government's commitment to environmental sustainability and reduced carbon emissions. “Businesses are adopting more energy-efficient processes and technologies to meet stringent energy conservation and emission reduction targets,” says Peter Schnickmann, Managing Director at Luwa Air Engineering (Shanghai). He notes an investment trend for solutions helping Chinese companies cut operational costs and minimize their carbon footprint.

To enhance the reputation of both companies and products – and boost the image of the entire industry – the environmental impact needs to decrease. Priorities are saving water and waste, as well as reducing, replacing or completely eliminating the use of harmful substances. China has a strong demand for environmental-friendly solutions and sustainable technologies.

Customer-oriented in weaving
The huge number of Chinese fabric producers calls for an immense volume of weaving machinery to be supplied by international and local providers. Swiss machinery manufacturers hold an impressive share of this business.
Chinese weavers require advanced technology, with increasingly higher standards of efficiency. In weaving preparation, latest solutions match the speed, quality and reliability now wanted. Weaving machines too offer the eco-efficiency, performance, and ease of use needed, with innovations that extend the scope of sustainable weaving, and open-platform systems configurable to weavers’ specific operations. A huge increase in demand for technical textiles in recent years has been driven by applications such as carbon fiber, aramid and glass fiber.

Profitable in spinning
China’s competitive advantages come from its large-scale and integrated manufacturing capabilities, along with the use of advanced automation and digitization technologies. Spinners aim to capitalize on extended market opportunities, with more economical production. The latest air-jet spinning machines serve these goals, allowing exceptionally low production costs per kilogram of yarn, coupled with high flexibility and reliability. Sustainable yarns are in great demand.

The automation trend in spinning mills focuses on connecting production processes. Data is used to ensure the highest quality standards, most efficient raw material usage, reduction of waste, and energy savings. To make spinning mills more competitive, latest solutions combine cutting-edge hardware, data-enabled software and renowned textile expertise.

DITF: Lignin coating for Geotextiles Photo: DITF

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.
