VDMA Textile Machinery: Planned PFAS ban threatens important textile machine components

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.

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.

Conventional fiber-reactive methods of dyeing cellulosic and synthetic yarns are multi-step resource-intensive processes that use up to 95 liters of water per kilograms of colored yarn and discharge approximately 94 liters of effluent.

In contrast, the innovative QuantumCOLOUR™ process injects pigment and a binder directly into the yarn, using only 0.95 liters of water per kilograms of colored yarn while producing zero effluent. This represents an unprecedented reduction of 98% in water consumption alongside zero wastewater discharge, zero discharge of harmful chemicals, 73% decrease in carbon footprint and 50% reduction in energy use.*

With Archroma, textile manufacturers and apparel brands can add further value to the QuantumCOLOUR™ process with tailor-made system solutions, including JUST COLOR. This formaldehyde-free** pigment coloration system is based on Archroma’s revolutionary Printofix® pigment dispersions and Helizarin® binders to deliver exceptionally soft fabrics with high fastness and durability, while also enabling energy and chemical savings and higher productivity.

BEZAKTIV ONE: New Reactive dyes range by CHT

  • Reactive dyes for water and energy saving dye processes with significantly shortened process time

BEZAKTIV ONE covers a broad color spectrum with tinctorial very strong dyes. This enables a cost-efficient dye process with significantly less dye and salt. The excellent wash-off behavior allows short rinse cycles at lower temperatures and therefore offers further ecological and economic advantages. The dyes are particularly suitable for durable textiles due to their good multiple wash fastness.

Cellulosic fibers are often dyed with reactive dyes, as these are commercially available in a wide range of colors that result in dyeings with high wash fastness. However, reactive dyeings require a lot of water due to the necessary rinsing processes. Due to increased ecological requirements, the development of energy and water saving processes is not just a trend, but rather a core prerequisite for new dyes.

A minimal number of rinsing baths and generally lower temperatures for dye exhaust, rinsing and soaping contribute to an overall efficient water and energy saving dyeing processes.

A minimal number of rinsing baths and generally lower temperatures for dye exhaust, rinsing and soaping contribute to an overall efficient water and energy saving dyeing processes.

BEZAKTIV ONE dyes can be dyed, rinsed and soaped between 40 and 60 °C. Therefore, the BEZAKTIV ONE exhaust dyeing process is significantly shorter compared to conventional reactive dyeing processes, where temperatures between 60 and 98 °C are required. This advantage means savings in process time and higher productivity for the textile dyer.

The advantages become particularly clear when dyeing medium to dark shades with the BEZAKTIV ONE process. Due to the high fixation level in combination with good color build-up dark shades can be matched with lower dye concentrations of BEZAKTIV ONE than with conventional bifunctional reactive dyes. The addition of the auxiliary COTOBLANC SEL in the second soap bath has an additional positive effect, so that a washing process with low water and energy consumption generates excellent wet fastness properties on the textile.

New technology purifies wastewater from textile dyeing by using graphene

The substance graphene can become increasingly important as a component in textile catalysts when purifying water from textile dyeing as has been shown in a recently completed doctoral project at the University of Borås.

In his project, Milad Asadi, a new doctor in Textile Technology, has modified conventional yarn by encapsulating iron particles in graphene and developed a multifunctional smart e-textile. The focus was on developing a method for purifying wastewater from textile dyeing. The smart e-textile acts as a catalyst that causes the substance hydrogen peroxide to be formed, which is needed in order to break down pollutants in wastewater.

The project has generated a complete textile reactor for the treatment of wastewater through the so-called electro-Fenton technology, which is mainly used industrially to purify wastewater. The novelty of the technology is to use the properties of both graphene and iron, which is the main catalyst.

The novelty of the technology is to use the properties of both graphene and iron, which is the main catalyst.

“Previous research has mainly been about the treatment of wastewater by using chemicals to break down the textile dyes. My project is the first where graphene, which is electrically conductive, is used to encapsulate iron. The e-textile can also be used several times, unlike when chemicals are used and which are then rinsed off. The challenge in the project was to scale up the technology so that the treated yarn can be fed into automatic knitting machines”, explained Milad Asadi.

The e-textile catalyst can be reused and hydrogen peroxide is formed internally inside the reactor, which reduces the use of biological catalysts, making the technology more sustainable compared to chemical methods.

EURATEX: Future of the European textile & clothing industry is at stake

  • European Textile Industry calls for immediate action to tackle the energy crisis;

The European textile & fashion in Europe, represented by EURATEX, calls for a single European strategy to tackle this energy crisis. To safeguard the future of the industry, a revision of the electricity price mechanism is necessary and an EU wide cap on gas prices at 80€/MWh. Special company support needs to be granted to avoid bankruptcy and relocation of textile production outside Europe.

Gas and electricity prices have reached unprecedented levels in Europe. Due to severe global competition in the market that characterizes the European textile & clothing industry, these cost increases are impossible to pass on to customers. This has already led to capacity reductions and production stops. Closures and the shift of production outside Europe are being forecasted should the current situation persist, leading to further de-industrialization of our continent and increased dependency on external suppliers.

Special company support needs to be granted to avoid bankruptcy and relocation of textile production outside Europe.

Gas and electricity prices have reached unprecedented levels in Europe. Due to severe global competition in the market that characterizes the European textile & clothing industry, these cost increases are impossible to pass on to customers. This has already led to capacity reductions and production stops. Closures and the shift of production outside Europe are being forecasted should the current situation persist, leading to further de-industrialization of our continent and increased dependency on external suppliers.

Specific segments of the textile industry are particularly vulnerable. The man-made fibres (MMF), synthetic and cellulose-based fibres, industry for instance is an energy intensive sector and a major consumer of natural gas in the manufacturing of its fibres. The disappearance of European fibre products would have immediate consequences for the textile industry and for society at large. The activities of textile dyeing and finishing are also relatively intensive in energy. These activities are essential in the textile value chain in order to give the textile products and garments added value through colour and special functionalities (e.g. for medical applications).

The European textile industry calls for an EU-wide cap on gas prices at €80/Mwh, and a revision of the price mechanism for the electricity market, to reduce the huge price gaps with our foreign competitors.

Governments should ensure that critical industries, such textiles and all its segments, are able to ensure gas and electricity contracts towards the end of the year at an affordable price. Stable and predictable energy supply is of the utmost importance. Gas restrictions and rationing must only be used as a last resort. No mandatory consumption cuts should be foreseen.

In addition to these measures under discussion, currently a proliferation of contradictory, uncoordinated national initiatives to tackle the energy crisis is observed. This has led to a de facto fragmentation of the Single Market, resulting in a chaotic policy and regulatory environment that adds a further strain on our supply chain, which is fully integrated at European level. Measures that guarantee a level playing field in the EU are utmost important.

EURATEX President Alberto Paccanelli explained: “Given the current situation, a scenario where entire segments of the textiles industry will disappear can no longer be excluded. This would lead to the loss of thousands of companies and tens of thousands of European jobs and would further aggravate the dependency of Europe to foreign sources of essential goods. This applies specifically to SMEs who need temporary support measures (e.g. state aids, tax relieves, energy price cap) to survive the current crisis and to prepare for the green transition in the longer run.”

Alchemie Technology asks fashion industry to reduce emissions

Alchemie Technology, an innovator of low energy, waterless, textile dyeing and finishing technology, is calling on COP26 leaders to support the global fashion industry in the adoption of new manufacturing technology, which will dramatically reduce carbon emissions and fashion’s impact on climate change.

While the fashion industry is one of the most polluting on the planet, second only to oil and gas, and greenhouse gas emissions from textile dyeing at around 3% of global emissions outweigh that of all international flights and maritime shipping combined, it is an industry that can also reduce CO2 emissions the fastest, just by changing the way it dyes fabrics.

Fabric dyeing is the most polluting part of fashion and activewear manufacturing, involving industrial scale dye baths and huge amounts of dye chemicals, steam, electrical power, and consequent high CO2 emissions.  Repeated washing of the dyed fabric, required to remove dye residue, is responsible for 20% of the world’s wastewater pollution and excess dye is discharged into waterways, affecting the health of some of the world’s poorest communities. In more regulated areas, water pollution is reduced through reliance on energy intensive water treatment plants.

However, an environmental step change can be achieved by adopting new digital technology that can dye fabrics with an 85% reduction in energy consumption and a dramatic 95% reduction of the 1.3 trillion litres of water currently used by the industry each year.

For example, dyeing one polyester shirt using current methods generates 4.5 litres of wastewater and produces 0.17 Kg of CO2, compared to low energy digital technology, which uses less than 0.2 litres of water and reduces carbon emissions to 0.03 Kg.  Multiply these numbers by the billions of garments dyed each year and the scale of the environmental problem, if nothing changes, is clear to see. Equally, the amount by which the textile industry can improve its carbon footprint is dramatic and can be done quickly if action is taken now.

Dow and Cotton Inc. are combining expertise for more Sustainable Fashion

Combining expertise for more sustainable fashion
Ever wonder how much water was used to make your favorite cotton T-shirt? About 2,700 liters, or roughly three years of drinking water. What first comes to mind is probably the water that was essential to growing the cotton crop. Surprisingly, cotton is a drought-tolerant plant, and often less recognized is the strain that can be put on water resources to dye cotton textiles.

Progress is being made across the industry to lessen the strain on our precious water resources. Over the past several years, Dow collaborated with Cotton Incorporated to research and validate their product, ECOFAST™ Pure Sustainable Textile Treatment, that can help drastically reduce water and chemical use during the dyeing process. Major fashion brands are integrating it into their supply chain to dye more sustainably, without sacrificing color or quality.

Over the past several years, Dow collaborated with Cotton Incorporated to research and validate their product, ECOFAST™ Pure Sustainable Textile Treatment, that can help drastically reduce water and chemical use during the dyeing process. Major fashion brands are integrating it into their supply chain to dye more sustainably, without sacrificing color or quality.

Problem
Cotton dyeing is very resource-intensive and puts strain on local waterways. A large amount of water is used in the dyeing process – up to 5 trillion liters a year, or nearly enough to supply all of humanity with drinking water. Significant amounts of chemicals and dye are needed to get the desired colors consumers expect too. This is part of the reason textile mills account for 20% of industrial water pollution globally. Wastewater from the dyeing process can be polluting and require costly treatment and these challenges are found in regions that already face water scarcity.

Solution
Reforming processes in an industry as established as textiles is no easy feat. Collaboration across the sector is needed to bring about sustainable change. With that in mind, Cotton Incorporated approached Dow. They wanted help scaling a cotton technology to support more sustainable textile dyeing.Leveraging Cotton Incorporated’s industry expertise and Dow’s material science knowledge, they worked together to understand and validate the benefits of our patented ECOFAST™ Pure Sustainable Textile Treatment.

How can colors be more responsible?  
ECOFAST™ Pure is a pretreatment applied before the dyeing process to produce cationic cotton. This means the charge of cotton is permanently changed from negative to positive, so it acts like a magnet to attract negatively charged dye to the material. How does that benefit the textile mill? It significantly decreases the amount of water, chemicals, dye and energy needed to color cotton. A third party reviewed and validated life cycle assessment, available by request, helped further prove the benefits.

Dyeing industry first for 7H with imogo

Swedish commission dyeing company 7H Färgeri is looking to propel itself to the forefront of sustainable fabric production with the installation of the first industrial scale imogo Dye-Max spray dyeing line.
Currently under construction, the line will be delivered in the first week of March to the 7H plant close to the Swedish city of Borås. It will have a full working width of 1.8 metres with an operating speed of up to 50 metres for the reactive dyeing of cellulosic fibre-based fabrics. In addition, it will be capable of carrying out the application of a wide range of fabric pre-treatments and finishing processes, providing the company with unbeatable flexibility in production.

A proven Mini-Max laboratory unit for pre-determining application volumes and colour matching will also be delivered as part of the contract.

With the potential to slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems, the DyeMax has gained considerable attention since the concept was outlined and a prototype machine constructed in 2019.

Pilot scale trials have subsequently been carried out with many well-known international textile companies and their brand partners.
The application unit of the Dye-Max consists of a closed chamber containing a series of spray cassettes with precision nozzles for accurate and consistent coverage, in combination with the patented imogo Pro Speed valve that controls the volume to be applied.

Control and precision
“We are achieving an extremely low liquor ratio of around 0.5-1 litres per kilo of fabric and we fully control the pickup, applying precisely what is required to the specific fabric,” says imogo founding partner Per Stenflo. “Compared to traditional padders there is no contamination of the dyebath or dilution of the dye liquor to worry about.
Fast changeovers with virtually no waste together with a high production speed enable a high productivity and unmatched production flexibility. The system is also equipped with an exhaust system and droplet separator to ensure that the environment around the unit is safe and free from particles.

The imogo Mini-Max meanwhile frees up valuable production time by avoiding wasteful pre-runs. The user simply sets the recipe with the Mini-Max and transfers the parameters to the Dye-Max recipe database for the system to be fully production ready.

7H Färgeri was founded in 1935 and has established itself as the Nordic region’s most complete dyeing and processing plant, specialising in technical and functional textiles for the automotive and soft furnishings sectors, as well as functional and protective clothing.

The family-owned business is now run by brothers Johan and Peter Engelmann.
“We are pleased to be pioneering a sustainable first for the dyeing industry,” said Johan Engelmann. “Our goal is to offer the market products and services with the highest quality in the most climate-smart and sustainable way, and imogo’s spray technology will give us the opportunity to offer innovative new services and products to both existing and new customers. It will be a very exciting journey.”

World Congress on Textile Coating
On February 12th Per Stenflo will make a presentation entitled ‘Transforming Textile Dyeing’ during the online World Congress on Textile Coating which is held over four days, between February 11th and 19th.
