From the Sector

Haelixa, a pioneer in traceability with DNA markers, appoints Nina Marenzi to its Advisory Board. With her experience leading the Future Fabrics Expo and connecting brands with innovators throughout the textile supply chain, Marenzi will offer strategic guidance to further Haelixa’s mission of building brand trust across the textile industry.

Nina Marenzi established The Sustainable Angle, a non-profit organisation, 2010 to minimise the fashion industry's environmental footprint. In 2011, she established the Future Fabrics Expo, a global platform showcasing innovative, lower-impact materials to drive sustainability in fashion. With her Master’s in Sustainable Agriculture and Rural Development from Imperial College, London, and the 15 years heading The Sustainable Angle and its Future Fabrics Expo, Marenzi has been instrumental in connecting brands with responsibly produced materials, advocating for transparency, and educating the industry on sustainable sourcing.

"We are pleased to welcome Nina to Haelixa’s Advisory Board,” stated Haelixa’s CEO, Patrick Strumpf. “As supply chain due diligence becomes a bigger concern, her insights will support our efforts to empower brands with reliable solutions, ensuring brand trust."

Haelixa has partnered with C&A, one of Europe’s leading fashion retailers, to advance the traceability of its organic cotton. The partnership stems from C&A’s commitment to working with others in the apparel industry to pilot and scale innovation. C&A’s targets include supporting the growth of organic cotton without synthetic pesticides and fertilisers, resulting in cleaner waterways, healthier ecosystems, and lower farmer costs.
 
The partnership between Haelixa and C&A began in 2022 with a pilot project, and since then, they have continuously worked together to trace raw materials. The result is this agreement with Haelixa to mark their organic cotton for the next three years. Using Haelixa’s DNA markers, C&A can trace the journey of its organic cotton from farm to finished garment. According to the C&A Sustainability Report, they are working with other organisations to foster organic cotton farming.  
 
Alexandre Saus-Salas, Head of Sourcing at C&A, commented, “Transparency and ethical sourcing are crucial in our supply chain. As part of our commitment to traceability, we have begun implementing Haelixa DNA within our organic supply chain. This gradual rollout will continue over multiple seasons in 2025, with an impact foreseen over the next three years.”
 
Haelixa’s solution utilises DNA markers to create a tamper-proof, verifiable traceability that tracks organic cotton throughout the supply chain. The cotton, sourced through CottonConnect, is marked with unique DNA, which acts as a specific identifier. Once applied, the cotton is tested throughout the supply chain to verify the material using forensic PCR tests. Traceability with the fiber-forward approach ensures the final garment materials are authentic.  
 
The marking ensures the authenticity of organic cotton and mitigates the risk of sourcing from regions associated with forced labour.  Using the Haelixa markers enables C&A to make reliable statements about the presence of organic cotton in its products marked at the field level (in the ginning process).
 
Patrick Strumpf, CEO of Haelixa, noted, “Trust is the foundation of transparent storytelling. By tracing organic cotton from farm to finished garment, we empower brands like C&A to tell an authentic story, fostering greater consumer confidence in their sustainability efforts.”
 
This project is one of the initiatives that C&A has undertaken to enhance accountability through its supply chain. One of the goals listed in their Sustainability Report is enabling customers to make informed choices by increasing transparency around products and the company. The traceability of organic cotton demonstrates that innovation can support business success through customer trust.

Haelixa, the trailblazer of physical traceability solutions, has partnered with Trudel Silk, a market leader for sustainable organic and recycled silk products. This collaboration brings traceability and transparency to silk production.

Silk is one of the finest and smoothest fabrics; the better the quality of the silk, the more luxurious it feels to the touch. To create the best quality silk, the conditions for mulberry cultivation must be up to the highest standards. A healthy micro-ecosystem in the fields translates to top-grade silk cocoon quality. At Trudel, this is the environment they have created for the vertical integration of their business. Trudel aims to succeed at every stage of the process, which can only be accomplished through the active involvement and visible cooperation of all market players. These players include farmers, reeling mills, twisting/spinning mills, weaving mills, dyeing and printing mills, and brands. They are involved in every step, from the cultivation of mulberry trees to the production of silk fabrics.

Haelixa and Trudel have collaborated to improve silk’s robust and consistent traceability. As the demand for validation of the silk value chain increases, they have partnered with groups from Italy and Asia to develop a unique solution that uses DNA markers to trace the entire supply chain of silk production. This innovative approach ensures each silk product’s ethical sourcing.

The silk fibers used in their spun silk yarns are marked with a specific DNA per farm set selected by Trudel. Throughout the supply chain, samples of yarn, fabrics, and finished products undergo testing to verify the presence of original silk fibers. Based on the reporting, the brand can trace the finished accessories or garments to Trudel.

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.

The steering committee for the Denim Deal has announced that Haelixa, the Swiss standard in physical traceability, is approved as a new signature. The Denim Deal is an international collaboration of more than 50 private and public sector companies united in the commitment to produce denim more circularly.

The Denim Deal aims to close the loop and achieve change in the value chain. Based in Amsterdam, the group is working towards a circular economy where textile waste no longer exists. The brand and manufacturing members pledge to work towards using 5% recycled post-consumer cotton in all future denim collections and produce 3 million denim jeans made with 20% recycled post-consumer cotton.

Coordination of the Denim Deal is led by Roosmarie Ruigrok, where the objective is to unite potential allies who have made the journey to circularity a priority. She has been working to improve sustainability in textiles for more than two decades and is an expert on enrolling the correct stakeholders to instigate change. Ruigrok states, "a circular supply chain in the textile industry is like a well-prepared machine - it ensures that every part of the production process runs smoothly, from sourcing post-consumer materials to delivering well-made finished products to customers. It not only drives efficiency and profitability but also builds trust among stakeholders and fosters sustainable practices - we welcome Haelixa who offers a trustful traceability solution."

Over the last few years, the demand for the technology in recycled denim has grown as brands are asked to validate their recycling claims. Haelixa’s unique DNA solution marks and traces fibers from the source to retail. Using DNA to mark the recycled post-consumer cotton, Haelixa substantiates claims by testing the final garment to validate that the marked waste is present.

The Denim Deal is pushing to lead the change in how denim is made. Changing the standards of operation is always challenging, and traceability is a key to authenticating recycled claims. “We are committed to promoting the use of recycled fibers through traceability and thrilled to align with this group,” said Holly Berger, Haelixa’s Marketing Director. “The goals of the Denim Deal support our vision for a circular economy.”

Haelixa, the Swiss traceability company and Damteks Textiles have announced a collaboration to mark and trace recycled acrylic fiber. Damteks is offering their recycled yarn to customers whereby they are able to place an order with the unique Haelixa DNA already attached.

The Haelixa solution is DNA markers which are solved in liquid and applied to fibers as a fine spray. Spot checks are completed after spraying to determine the presence of DNA and identify the product. The test is based on PCR technology that is 100% reliable and has forensic validity.

Damteks saw an increase in demand for blended yarn in the last year. The request is most often a composition of 30% recycled fiber with 70% standard fiber. Brands are looking for options to be more sustainable and Damteks proactively sought out an answer. They are offering the yarn with Haelixa DNA to validate the recycled acrylic in the mix.

The haelixa team visited the Damteks recycling facility in Istanbul to kick off the partnership that will continue throughout 2023. The traceability program has the DNA sprayed on the recycled fibers before spinning. The project also saw the use of a tailored Haelixa liquid sprayer designed by the team based in Switzerland. When manufacturers do not have built-in moisturizing systems, Haelixa provides them with a custom unit to shower the DNA liquid onto the fibers. This sprayer is engineered to match the mechanical processing of the customer.

Damteks is a family-owned business that pride itself in carefully selecting environmentally responsible options for its production processes. On top of the certifications they have obtained including - GRS, RCS, GOTS, OCS - Damteks decided to have their products "Marked and Traced by Haelixa" to add additional credibility and reliability. Damteks plans to offer marked and traced by Haelixa yarn in different dyes as their offering to brands.

Under the United Nations Economic Commission for Europe (UNECE) initiative to enhance transparency and traceability in the garment and footwear industry, Haelixa realizes a pilot project with Costach Cooperative and Peruvian textile company Creditex to give sustainable rural cotton producers in Peru more visibility in the value chain.

In 2019, UNECE and United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT) have set up an initiative to drive transparency and traceability for sustainable value chains in the garment and footwear industry. The initiative is jointly implemented with the International Trade Centre (ITC) with financial support by the European Union. Haelixa is proud to be part of the group of experts that develops policy recommendations, traceability standards, and conducts projects to set traceability benchmarks. With the support of the +Cotton Project, implemented by the Food and Agriculture Organization of the United Nations (FAO) and the Brazilian Cooperation Agency (ABC) a pilot is being realized in this context to mark and trace the finest Pima cotton for Creditex directly at the gin in Piura, Peru. Haelixa’s DNA marker connects the actual lint cotton to the entry on a blockchain system provided by UNECE. The Haelixa technology ensures that the information about the product’s origin and the journey of the product along the value chain is always safely embedded into the product itself. The marked cotton will be used to make exclusive pajamas sets for Cat´s Pajamas. DNA traceability will enable the verification of the premium origin of Peruvian Pima cotton in the final garment produced using sustainable practices by family farmers associated with the Costach cooperative.

Costach is the main cooperative of cotton farmers in Peru. The cooperative consists of 5,200 family farmers in the Piura region, producing mostly extra-long fiber of Pima Cotton. Since 2017, the +Cotton project has been supporting the farmers with training on sustainable practices and has been providing technical assistance for improved markets access.

Creditex is vertically integrated from cotton ginning to fine thread, up to the production of high quality apparel for international premium brands. The company takes social responsibility and environmental stewardship very seriously and therefore makes a strong partner for this project, empowering the cotton family farmers that hold the majority of cotton production in Peru.
