New test method for textile microplastics

  • Standard assesses fibre release, biodegradation and ecotoxicity for the first time

Testing service provider Hohenstein has worked with the project partners Trigema, Freudenberg, DBL ITEX and Paradies to create a new standardized test method for detecting and classifying the environmental effects of textiles during washing. DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

Studies have shown that washing textiles releases microfibres into the wash water, which cannot be sufficiently retained by wastewater treatment plants. Synthetic fibres pose the greatest risk to the environment because of their longevity and inability to biodegrade. However, Hohenstein project manager Juliane Alberts does not give the all-clear for biodegradable fibres and natural fibres: "Biodegradability alone does not mean that pure natural fibres, for example, are completely harmless to the environment. They, too, remain in ecosystems until they completely degrade and can also have a negative impact. In addition, additives, auxiliaries or finishes used in textile production can further slow the degradation process and leach into the environment."

The new standard enables textile producers and suppliers to test, evaluate and compare products for fibre release during washing and environmental impact. Juliane Alberts sees this systematic evaluation as an opportunity for the textile industry to take the initiative on environmental impact: "Our reliable data can be used as a basis for more targeted product development. This is a way to actively and consciously control further environmental pollution."

OEKO-TEX® Association turns 30: Trust, Safety, Sustainability

The vision of the OEKO-TEX® Association, which was founded in March 1992 through a partnership between the Hohenstein Research Institute and the Austrian Textile Research Institute (OETI), is still reflected today in the organization's core values: trust, safety, and sustainability. For three decades, OEKO-TEX® has pursued the goal of building trust for companies and consumers and enabling them to make responsible decisions to protect people and the planet. "Our services bring transparency to the international textile and leather industry supply chains," says OEKO-TEX® Secretary General Georg Dieners. "They enable all stakeholders to make mindful decisions that help preserve our planet for future generations."

"Our services bring transparency to the international textile and leather industry supply chains," says OEKO-TEX® Secretary General Georg Dieners. "They enable all stakeholders to make mindful decisions that help preserve our planet for future generations."

OEKO-TEX® market leadership
In 1992, 20 years before the United Nations announced the Sustainable Development Goals (SDGs), OEKO-TEX® launched STANDARD 100 by OEKO-TEX®, now one of the best-known labels for product safety.
"It emerged from the Schadstoffgeprüft nach ÖTN 100(tested for harmful substances according to ÖTN 100), developed by OETI in 1989 to address increasing public interest in textile ecology and health," the Austrian Textile Research Institute reminds us. The limit values and test methods on which STANDARD 100 by OEKO-TEX® is based were internationally standardized and are adapted to the latest scientific findings and legislation at least once a year - a principle that is applied to all OEKO-TEX® standards. Prof. Dr. Stefan Mecheels, the owner of the textile testing service provider Hohenstein, adds: "From the very beginning, we have considered the needs of all players in the textile value chain and continue to create solutions for current and future market requirements."

At least seven SDGs are firmly integrated into the OEKO-TEX® product portfolio. For example, Good Health & Well-Being (SDG 3) and Clean Water & Sanitation (SDG 6) are reflected in the STeP by OEKO-TEX® factory certification, and Responsible Consumption & Production (SDG 12) and Climate Action (SDG 13) are implemented through the comprehensive MADE IN GREEN by OEKO-TEX® product label.

Today, the international association consists of 17 independent research and testing institutes focused on textile and leather, with contact offices in over 60 countries. They are responsible for the joint development of the test methods and limit values in the OEKO-TEX® Standards and carry out laboratory tests and factory audits according to globally uniform specifications. These comprehensive product and process audits to ensure appropriate risk management, consumer and environmental protection, and legal compliance. With their wide-ranging research and development, the accredited OEKO-TEX® test institutes provide important insight for innovations within the textile and leather industry. They work in close cooperation with manufacturers and make a significant contribution to the development of high-quality textile and leather products at all stages of the value chain.

Mirror of social and political development
Being close to the market, and ideally, one step ahead is essential to supporting companies who are adapting to constantly changing conditions and meeting consumer expectations. Therefore, the development of OEKO-TEX® is not only a reflection of scientific knowledge but also of social and political trends. The focus is always on standardizing sustainable action and measures and making it easier for the industry to quickly and comprehensively implement sustainability goals.

Exchange with third parties is particularly valuable for this purpose. OEKO-TEX® participates in various international multi-stakeholder initiatives such as the Organization for Economic Co-operation and Development (OECD), the Partnership for Sustainable Textiles, the ZHDC (Zero Discharge of Hazardous Chemicals), and Greenpeace.
In addition to cooperation with external multi-stakeholder initiatives, the OEKO-TEX® International Advisory Board (IAB) meets annually. The core function of the IAB is to help review consistent and market-oriented Standards development proposals by the OEKO-TEX® Working Groups. In addition, OEKO-TEX® is conducting a public stakeholder consultation to gain further insights from all interest groups, which it will integrate into further development of the Standards.
Using three decades of experience for the future
The founding goal of enabling responsible choices that preserve our planet for future generations has become increasingly urgent over the past 30 years. So, OEKO-TEX® is even more resolute than ever in developing comprehensive solutions. We stand by industry and consumers as a trusted partner for the challenges ahead. In addition to the IMPACT CALCULATOR launched in January 2022, which helps STeP by OEKO-TEX® certified production facilities reduce their carbon emissions and water consumption, this summer, the association will launch a service to help companies transition to the upcoming Due Diligence Laws.

Hohenstein: New quantitative method to detect genetic modifications in organic cotton

There has been a sharp rise in demand for organic cotton products. Compared to conventionally grown cotton, the cultivation of organic cotton requires the renunciation of genetically modified seeds, chemical pesticides or fertilisers. Nevertheless, genetic modifications are repeatedly found in textiles that are falsely labelled with organic claims. Often, available certification systems are not backed up by lab testing. At best, they only take random seed samples. Textile testing specialist, Hohenstein, has developed an assessment method specifically for cotton. This new DNA analysis method makes it possible to ascertain the amount of genetically modified cotton contained in products. This is good news for textile industry stakeholders who will be on the safe side in terms of quality control and labelling of organic cotton products.

This new DNA analysis method makes it possible to ascertain the amount of genetically modified cotton contained in products. This is good news for textile industry stakeholders who will be on the safe side in terms of quality control and labelling of organic cotton products.

First step: qualitative screening and identification. Second step: quantification of genetically modified cotton.
For qualitative screening, Hohenstein experts had developed molecular biological detection systems to make clear yes/no statements about genetically modified cotton. Testing can be applied to all kinds of materials, from raw cotton to chemically untreated yarns and fabrics. In addition, Hohenstein is one of only a few laboratories in the world accredited to test for GMOs in accordance with the ISO/IWA 32:2019 protocol. Its method provides reliable evidence of the presence or exclusion of genetic modification in cotton textile precursors.

Once qualitative proof of genetic modification is obtained, Hohenstein experts begin quantifying the type and extent of the genetic modifications. To do this, they use DNA analysis to search for different cotton lines known to contain genetic alterations and quantify the proportion. Only by pinpointing individual genetic modifications and quantifying the extent of modification is it possible to provide precise information on whether there is an extremely small proportion of contamination, or whether larger proportions of GMOs have been mixed in. This offers clear benefits to manufacturers, brand owners and retailers when it comes to supply chain transparency and fraud prevention.

Successful Roots

BÖNNIGHEIM - Textile testing and research partner Hohenstein has reason to celebrate: this year marks the company’s 75th anniversary. Now in its third generation of family ownership, the company will spend this landmark year expanding its foundation for the future. Owner Prof. Dr. Stefan Mecheels is proud: "Our motto, We live textiles, expresses exactly what has made us special for many decades - our collective enthusiasm for textiles and the opportunity to provide solutions that make a difference in the world.”

Successful Roots

Prof. Dr.-Ing. Otto Mecheels laid the foundation for an internationally-renowned company in 1946 when he founded the Hohenstein Institutes, a textile school in Hohenstein Castle. His son, Prof. Dr. rer. nat. Jürgen Mecheels modernized the Hohenstein Group’s business structures and expanded into new research and service areas such as textile finishing or professional laundries/dry cleaning. He helped to forever change textile safety with the STANDARD 100 by OEKO-TEX® certification system that protects consumers from harmful substances. Under Prof. Dr. Stefan Mecheels’ leadership since 1995, Hohenstein has been at the forefront of microfiber analysis, consistently perfected its created standards for comfort and compression testing and worked to reduce the industry’s ecological impact. Last but not least, the testing laboratory in Hong Kong, which has been in operation since 2011, and the Hohenstein textile testing laboratories in Bangladesh and India, which were opened in 2018, ensure even greater market proximity.

Solutions for the Global Textile Industry

Today, Hohenstein specializes in the testing, certification and research of all kinds of textile-related products. With a total of more than 1,000 employees at its headquarters in Bönnigheim and in more than 40 branches, contact offices and laboratories worldwide, the company faces the current challenges of the global industry.

"Textile sustainability remains a major focus for us and is woven through every decision we make," explains Stefan Mecheels. “Even services that are seemingly focused on innovation contribute somehow to longer lasting products, less waste and more safety. Our Digital Fitting Lab helps brands leap forward with digitized apparel development. Using modern 3D and 4D technologies and our traditional fit and pattern expertise, we help our clients design better fitting clothes with fewer prototypes and less waste.”

When SARS-CoV-2 struck, the company developed a quality label to easily identify non-medical, community masks that meet legal and functional requirements. The Hohenstein Quality Labels are independent proof with a high level of credibility among buyers and consumers.

Anniversary

Among the celebrations, Hohenstein plans to hold a mid-year press conference with regional and industry journalists. "We are celebrating this anniversary because we have succeeded in constantly adapting to the market and use our applied research to anticipate developments. For this I would first like to thank our employees, who, in keeping with the motto We live textiles, put their hearts and souls into their work. A very special thanks also goes to our customers, some of whom have been placing their trust in us for decades," says Stefan Mecheels, adding "I am convinced that we are positioned to continue our contribution in the future.
