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.

ITM at JEC 2023

From April 25th to 27th, 2023, the Institute of Textile Machinery and High Performance Material Technology (ITM) of TU Dresden will be exhibiting at the pavilion SAXONY! at JEC World 2023.

The ITM will provide a comprehensive overview of its current research in the field of machine and product development along the entire textile process chain.

The upcoming JEC 2023 exhibition will highlight innovative Customised Connective Cores (CCC), which are custom-made core-insert structures additively manufactured using cellular metal and a form-fit integrated insert. These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

Another highlight at the exhibition is the repair process for fibre-reinforced composites (FRP) developed at the ITM. Instead of mechanically grinding the damaged area, the matrix in the repair area is locally dissolved using a UV-rays-induced depolymerisation process. Damaged fibres can thus be replaced by a customized repair patch. Free yarn ends on the textile repair patches are spliced with the UV-exposed yarn ends in the repair area using an adapted splicing process. In this way, a very clean, simplified and mechanically improved repair area can be achieved compared to the state of the art.

The diverse possibilities offered by the structure and process simulation of textile high-performance materials and textile manufacturing processes will also be presented. By means of multi-scale modelling and simulation, a profound understanding of materials and processes is achieved at the ITM. Finite element models on the micro, meso and macro scale have been developed and validated for this purpose. Examples from current ITM research projects demonstrate the various possibilities and areas of application of modern simulation methods in the field of textile technology.

Moreover, an innovative process for the integral manufacturing of 3D rib-stiffened preforms with complexly arranged stiffeners in 0°, 90° and ± 45° orientation was developed and successfully implemented at the ITM. Due to the process-integrated structure fixation and the continuous fibre reinforcement between shell and rib structure, the 3D preforms are perfectly suited for the production of highly load-bearing FRP components with increased bending stiffness, which will be exhibited at JEC. Hence, the lightweight construction potential of high-performance fibres can be fully exploited.

A successfully established development are partially flowable 2D textile reinforcement fabrics that are continuously manufactured in one single process step. For this purpose, the entire process chain was developed at the ITM, which allows a cost-effective and high-volume production of load-bearing thermoplastic 3D FRP components with continuous fibre reinforcement between shell and stiffeners.

At JEC 2023, the ITM will also present a partially embedded textile latice girder as reinforcement for carbon concrete applications, which was produced by means of an innovative textile manufacturing process based on the multiaxial warp knitting technology. Through the development of a customized warp insertion, manipulation and take-off system as well as appropriate shaping methods, it is now possible to produce tailored textile semi-finished products, e.g. for use in wall and ceiling panels. These textile latice girders represent a resource-saving alternative to conventional steel girders due to the reduced among of concrete required and the additional cavity for media and cable guidance.

The integration of textile actuators and sensors in FRP provides structures with additional functionalities. The research and application of such interactive FRP with different matrix materials (e.g. with thermoset, elastomer or concrete matrix systems) for structural health monitoring or adaptive systems is one of the key research areas of the ITM.

Moreover, the development and implementation of innovative yarn constructions based on recycled high-performance fibres (e.g. rCF, rGF, rAR) for sustainable FRPs is successfully promoted at ITM. By use of a special carding machine, recycled fibres are opened up, separated and joined to form a wide, uniform ribbon. Subsequently, innovative hybrid yarn constructions made of evenly mixed recycled high-performance and thermoplastic fibres with variable fibre volume fractions can be manufactured by means of various spinning technologies. Selected yarn constructions and components will be showcased at JEC.

  • Turkish circular knitting market offers prospects in turbulent times

After a four-year, Covid-related break the German circular knitting machine manufacturer Mayer & Cie. is exhibiting with its Turkish representative Mayer Mümessillik (MMÜ) once more at the important International Textile Machinery Exhibition (ITM) in Istanbul. At Booth 713 in Hall 8, Mayer & Cie. will present three machines: the D4-2.2 X interlock machine, the OV 3.2 QCe for double jersey structures and the MV 4 3.2 II for single jersey fabrics. For the Mayer & Cie. and MMÜ team the focus will be on in-person contacts with customers, suppliers and partners. Despite the tense international situation both the manufacturer and its representative are positive about the medium-term outlook for the Turkish market.

  • Turkish circular knitting market offers prospects in turbulent times

After a four-year, Covid-related break the German circular knitting machine manufacturer Mayer & Cie. is exhibiting with its Turkish representative Mayer Mümessillik (MMÜ) once more at the important International Textile Machinery Exhibition (ITM) in Istanbul. At Booth 713 in Hall 8, Mayer & Cie. will present three machines: the D4-2.2 X interlock machine, the OV 3.2 QCe for double jersey structures and the MV 4 3.2 II for single jersey fabrics. For the Mayer & Cie. and MMÜ team the focus will be on in-person contacts with customers, suppliers and partners. Despite the tense international situation both the manufacturer and its representative are positive about the medium-term outlook for the Turkish market.

Turkey is a market with prospects
“The challenges that the global economy faces are at present enormously wide-ranging, of course,” says Mayer & Cie.’s Turkey specialist Stefan Bühler. “The Russian invasion of the Ukraine, supply chain outages, shortages of raw materials and skyrocketing energy prices all create uncertainty.” And then there is galloping inflation in Turkey and elections in 2023. Yet despite, and in part because of, this state of affairs Bühler and Kahraman Güveri, CEO of Mayer & Cie.’s Turkish representative MMÜ, hold a positive view of the market outlook for the years ahead. Large orders, especially for standard products, are on the increase, Kahraman Güveri explains. That leads to new investments, new companies and a growing demand for refurbished machines that then need to be replaced by new machines elsewhere. And former commission merchants are now enterprises in their own right.

“Apart from that, Turkey benefits from its proximity to Europe, transport routes are manageable,” says Stefan Bühler. “This location advantage attracts brand manufacturers who together with their orders bring new approaches, new designs and new technologies into the country.” And Turkey’s already very highly developed textiles sector benefits too. That, says Kahraman Güveri, is why one can be confident for the next few years, “at least for as long as nothing unforeseen happens”.

Established machines with that something special: OV 3.2 QCe for double jersey structures
The portfolio of machines that Mayer & Cie. is exhibiting at the ITM is tried, trusted and popular. The OV 3.2 QCe is a specialist for interlock fabrics and double jersey structures that it knits in both filament and synthetic fibre yarns. With a conversion kit the OV 3.2 QCe also qualifies as a producer of 8-lock structures, spacer fabrics and fine gauges. The machine is available in a choice of three frames: from open-width and industrial to giant frame. Stefan Bühler, regional sales manager for Turkey, has this to say: “Not for nothing has the OV 3. 2 QCe been one of our most popular machines for years. It is mainly used for sportswear and for leisure- and outerwear.” In Istanbul the OV 3.2 QCe on show will be a 30-inch, E40-gauge model.

D4-2.2 X for fine rib and interlock fabrics
The double-jersey D4-2.2 X is an obvious choice for knitting fine rib fabrics of up to E28 gauge. Spacer and interlock fabrics are also part of the machine’s established repertoire. And it can produce elastomeric plating in both cylinder and dial cam. No matter which of these tasks is assigned to the D4-2.2 X, it performs it with impressive productivity.

MV 4 3.2 II for flexibility in the single jersey sector
In the single jersey sector, the long-established German firm delivers a literally fine solution. The MV 4 3.2 II on show at the ITM knits to an E38 gauge. The machine can also be supplied for gauges from E14 to E60. It is, in addition, highly flexible, with a repertoire that ranges from piqué and double piqué to one-thread fleece and smooth single jersey.
