From the Sector

Archroma has introduced a new bio-based durable water repellent (DWR) finish that helps mills and brands produce apparel that is soft to the touch and yet offers robust rain and stain protection and an improved sustainability profile.

PHOBOTEX® NTR-50 LIQ is designed to provide great water repellence on all kinds of fibers while achieving a soft handle and avoiding undesired effects like yellowing and chalk marking. It performs especially well on synthetic fibers and their blends, making it ideal for apparel, outdoor wear and home textiles.

The new DWR is based on 50% renewable carbon content based on ASTM D6866 and is free of per- and polyfluoroalkyl substances (PFAS) and formaldehyde. It is also crosslinker-free, which makes it more flexible in use. While offering good wash durability on its own, PHOBOTEX® NTR-50 LIQ can be combined with a crosslinker like ARKOPHOB® NTR-40, which has a biocarbon content of 40%, to further boost wash and/or dry-cleaning resistance.

Sportswear, fashion and home textiles treated with the PHOBOTEX® NTR-50 LIQ durable water repellent qualify for the High IQ® Repel assurance program. The High IQ® program assures consumers that these products deliver performance, protection and comfort and meet strict environmental standards.

Archroma will introduce its new Super Systems+ concept and highlight product innovations at Techtextil 2024, being held in Frankfurt, Germany from April 23 to 26.

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.

Baldwin Technology Company Inc. will showcase its TexCoat™ G4 precision spray finishing system at ITMA Asia 2023 (November 19-23, National Exhibition and Convention Center, Shanghai). ITMA Asia participants can stop by and see Baldwin’s wide array of TexCoat G4-applied fabric samples from textile mills around the world and experience what precision finishing feels like while learning how the technology eliminates chemistry waste on changeover, saves water, and achieves faster speeds through the stenter frame and relaxed dryer.
 
Baldwin’s team will be available to discuss how the company’s technology can meet the textile supply chain’s sustainability and carbon footprint goals while improving performance and saving money. In the context of a cost-sensitive global economy and an increased focus by brands, consumers and regulatory agencies on sustainability, customers are placing a premium on sustainability-advantage textile production.

TexCoat G4’s non-contact spray technology offers numerous advantages compared to outdated finishing-chemistry application methods. TexCoat G4 processes a wide range of low-viscosity water-based chemicals, such as durable water-repellents –  including PFAS-free, softeners, anti-microbials, easy-care and flame retardants. The company's technology uses the same chemicals as found in traditional pad baths with no special auxiliaries required.

Testimonial videos from Pincroft Dyeing and Print Works and Graniteville Specialty Fabrics along with a video highlighting Baldwin’s partnership with North Carolina State University will also be screened at their stand.

Rudolf GmbH, a provider of chemicals to the textile industry, can now offer side-by-side performance tests of the age-old “dip and squeeze” pad versus precision spray finishing with the delivery of Baldwin Technology Inc.’s TexCoat ™ G4 lab-scale unit.

The new TexCoat lab-scale unit at Rudolf’s Geretsried, Germany-based Customer Solution Center, tests the sprayability of chemicals on fabrics as an additional tool to help the market transition to precision spray with confidence in the performance and sustainability of the end result.
 
With Baldwin’s innovative system, the chemistry is precisely distributed across the textile surface and is applied only where it is required, on one or both sides of the fabric. The non-contact technology eliminates chemistry dilution in wet-on-wet processes, allowing full control of maintaining consistent chemistry coverage rates.
 
Plus, pad bath contamination is eliminated, and changeovers are only required when there is a change of finish chemistry. On wet-on-dry processes, the finish is applied with 50% of the amount of water required for pad finishing. Dryer fabric entering the stenter means less water to evaporate resulting in less energy and higher production speeds.
 
More specifically, with Baldwin’s TexCoat G4, textile finishers can track and control the finishing process. Changeovers are quickly performed thanks to recipe management, including automated chemistry and coverage selection. Furthermore, the system takes speed information from the drying process to insure exact coverage regardless of any change in speed. TexCoat G4 measures every drop of chemical usage ensuring that the amount of chemical add-on is precise.
 
In addition, the TexCoat G4 system can process a wide range of low-viscosity water-based chemicals, such as durable water-repellants including PFAS-free, softeners, anti-microbials, easy care resins, flame retardants and more. Baldwin’s technology utilizes the same chemicals used in the traditional pad bath, with no special auxiliaries required.

The EU's planned ban on the entire group of per- and polyfluoroalkyl substances (PFAS) would endanger many industrial processes, states VDMA Textile Machinery. Textile manufacturing would be affected twice – by missing important chemicals for technical textile production and by the lack of indispensable textile machine components. The latter would affect the whole supply chain from textile machinery manufacturers and its suppliers to the textile industry in the EU.

Solid PFAS parts are widely used in textile machinery production, especially where extreme conditions prevail. Verena Thies, Managing Shareholder Thies GmbH & Co. KG, explains: “Our textile dyeing machines are world leaders and set standards in efficiency and sustainability. They work under pressure at temperatures of up to 140° C using highly acidic, highly basic and/or oxidative or even reductive chemicals. This is precisely why PFAS is needed, for example, in seals and rings, flaps as well as valves for a long-lasting and high-quality machine concept – because there are no alternatives with qualitatively equivalent properties. In addition, PTFE semi-finished products enable a sliding and gentle contact with the textile fabric in ecologically important techniques in the transformation of textile wet finishing."

PTFE and also FKM are fluoropolymers (fluoroplastics and fluoroelastomers), a group within the broad PFAS range of about 10,000 substances which would be banned for production, use and sale in the EU. They are high-tech materials, and as so-called "polymers of low concern" are not a danger to the environment, according to the OECD. Furthermore, these components are installed inside a machine and exchanged or disposed of properly. PFAS such as PTFE and FKM must be exempted from the ban, demands the VDMA in its position paper.

"In this way, the association also supports the approach taken in Great Britain. With the 10,000 substances, everything is lumped together, although the various PFAS groups are very different," warns Dr Sarah Brückner, Head of VDMA Environmental Affairs and Sustainability. "We should take our cue from the UK and look at the substance groups in a differentiated way."
Apart from several types of dyeing machines, PFAS components are indispensable in textile drying machines (e.g., conveyor dryers, tumblers and stenters) and damping machines. They are also used in fully automatic chemical dispensing systems and pressure vessels for thermochemical treatment of textile recycling material, heat recovery systems and wastewater treatment technology. This means that a lot of machines needed for a sustainable textile production would be affected by the PFAS ban.

VDMA Textile Machinery will take part in the ongoing EU public consultation. The association will describe indispensable key functionalities and conditions of use in the textile machinery sector as well as the consequences for the companies and the customers in the EU if the ban is imposed. The consultation ends on September 25, 2023, and VDMA urged its members affected by the planned restriction to participate in the consultation at an early stage. This is the only way to ensure that the broad scope of the mechanical and plant engineering sector is represented.

• Harmful PFAS chemicals, used in thousands of consumer products, are shaping up to be the big environmental and health threat of our time. The EU is now the first in the world to propose a broad ban on these chemicals.
• Consumer brands worth more than €130 billion support the ban on PFAS.  
• Investors with assets in PFAS-producing companies are calling for an end to production.

Many companies are taking a stand against PFAS chemicals as the EU invites the public to give its opinions on the proposed ban on these harmful chemicals.

108 companies dedicated to phasing out PFAS chemicals from products and processes have joined the PFAS Movement, an advocacy campaign initiated by environmental NGO ChemSec that calls for comprehensive regulation of PFAS in the EU. The members comprise many well-known brands, such as Inditex, Urbanears and the Cookware Company, representing various industries— fashion, home goods, food, and personal care. The members are worth more than €130 billion in total revenue.

“A European ban on PFAS chemicals will have huge repercussions for all manufacturing industries and require much work for companies in the global supply chain. However, some parts of the industry oppose this ban, claiming that the change is too big to be justified. That’s why the support for a ban from such influential consumer brands as those in the PFAS Movement is so important. It’s a strong sign that businesses want to eliminate PFAS chemicals in products and processes”, says Anne-Sofie Bäckar, Executive Director at ChemSec.

A Hollywood Helping Hand
ChemSec’s PFAS Movement is not only supported by the brands but also by Hollywood actor Mark Ruffalo who became a PFAS activist after his involvement in the film Dark Waters. The film depicts the real-life events following the massive uncovering of PFAS contamination in the USA. As a result, several PFAS producers in the USA are now involved in multimillion-dollar lawsuits.

The health and environmental threats of PFAS, along with all the lawsuits, have also created attention among another influential group: institutional investors. Last year, 47 institutional investors with US$8 trillion in assets sent a letter to 54 chemical companies named by ChemSec, calling for them to halt the production of persistent “forever chemicals”.

The EU ban on PFAS
The proposed EU ban on PFAS is extensive and the first of its kind worldwide. The idea was initially initiated by Sweden, Denmark, the Netherlands, Germany and Norway, who have spent almost three years mapping the implications of a ban on PFAS chemicals in a dossier that expands over nearly 2000 pages. The proposal shows, among other things, that the emissions of PFAS were 75 000 tonnes in 2020. If this continues, the emissions are expected to sit at 4.4 million tonnes in 30 years. The emissions originate from the production and use of the many products that contain PFAS; furniture, cosmetics, electronics and many more.

The Global Organic Textile Standard is pleased to announce the release of GOTS Version 7.0, which features an expanded scope of environmental and social criteria while maintaining a standard that is practicable for industrial production and appropriate for a wide range of products. During the regular year-long revision process, international stakeholders with expertise in organic production, textile processing, textile chemistry, human rights and social criteria, as well as representatives from industry, NGOs and civil society organisations, contributed to the new Version 7.0 through multiple consultation rounds. Final decisions were made by the multistakeholder GOTS Standard Revision Committee.

GOTS Version 7.0 provides a comprehensive solution for companies who want to produce organic textiles ensuring compliance with environmental and human rights due diligence along the entire supply chain, from field to finished product. With full traceability from origin to destination, GOTS certification provides an efficient means of verifying genuine sustainability efforts. GOTS 7.0 introduces new requirements to conduct risk-based due diligence of Certified Entities’ own operations and their supply chains based on the UN Guiding Principles for Business and Human Rights and the OECD guidelines. The Social Criteria section was substantially revised to include a broader human rights-focused approach. GOTS 7.0 now allows recycled organic fibres as additional materials. Key requirements, such as certified organic fibre content, a general ban on toxic and harmful chemicals such as PFAS, conventional cotton and virgin polyester restrictions, and social compliance management, are maintained in GOTS Version 7.0.

Some of the changes in Version 7.0 include:

• GOTS and the Manual for the Implementation of GOTS were restructured, and sections were grouped to reflect the standard’s scope.
• New due diligence criteria ensures that Certified Entities address their actual and potential negative impacts on human rights and the environment.
• GOTS Environmental Criteria, Product Stewardship, and Environmental Health and Safety (EHS) requirements will also apply to the subcontractors of chemical formulators.
• Criteria for the incoming organic material have been made stricter.
• Quinoline is included among the prohibited substances and some existing restrictions have been made tighter such as of “aniline, free”, residue limit is decreased to 20 mg/kg from 100 mk/kg.
• GOTS 7.0 reduces the permissible quantity of recycled synthetic (polymer) fibres in its certified products, taking into account the disadvantages associated with recycled synthetics, such as microplastics and poor quality.
• In the pursuit of circularity, GOTS will allow use of recycled GOTS Goods waste as an additional fibre in its certified products.
• GOTS Human Rights and Social Criteria will now require Certified Entities to respect internationally recognised human rights protocols, including the International Bill of Human Rights and other international human rights treaties.
• Criteria concerning Discrimination, Violence and Harassment were revised to make them more comprehensive and include the International Labour Organisation (ILO) Violence and Harassment Convention (C190).
• Certified Entities are now required to develop a plan to cover the living wage gap.
• GOTS Occupational Health and Safety criteria were revised to consider best international practices and recommendations from the ILO.

The EU's plans to ban PFAS (per- and polyfluoroalkyl substances) chemicals will have an immense impact on companies globally. Perhaps even more than expected, as many manufacturers are unaware that they may have PFAS chemicals in their product line. A new online tool, launched today by NGO ChemSec, will help to solve this problem.

Just a couple of weeks after the big PFAS restriction proposal in the EU was published, ChemSec launches the PFAS Guide, which helps companies investigate the use of persistent chemicals within their businesses. The main feature of the PFAS Guide is the searchable database uncovering different PFAS uses and functions. The online tool also provides guidance on different aspects of the phase-out process from regulation and investigation all the way to testing and supply chain communication.

“We’ve been working to support companies in chemical substitution for a long time, and the last few years we’ve gathered a group of companies working specifically on the PFAS issue. The discussions with them made it clear to us that a main challenge is understanding if and where in your business you may have PFAS”, says Dr. Anna Lennquist, Project Leader for the PFAS Guide.

PFAS are a source of growing concern
It has been estimated that 95 percent of all manufactured goods rely on some form of industrial chemical process. A large share of the chemicals used in these processes have been linked to adverse impacts on human health and the environment. PFAS are a clear example of this problem. PFAS have been manufactured and used in products such as make-up, non-stick pans, water- and greaseproof textiles, food-packaging materials, and firefighting foam since the 1950s and are still used in a wide variety of products around the world today.

But they are also substances of growing concern due to their problematic properties. Per- and polyfluorinated alkyl substances (PFAS) are a group of several thousand man-made chemicals that accumulate in the environment and cause health impacts for generations. They are, for example, linked to cancer, lung disease, diabetes, reproductive abnormalities and learning difficulties. Since PFAS do not degrade, these “forever chemicals” are now so widespread that is safe to say that every single human being on the planet have detectable levels of these toxic chemicals in their blood.

A couple of weeks ago, a big proposal to restrict PFAS in the EU was published. The five EU Member States behind the proposal submitted a broad restriction proposal that clearly shows the need for the industry to put all resources into phasing out all PFAS substances.
