From the Sector

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

Lenzing Group, a global producer of wood-based specialty fibers, is celebrating the 40th anniversary of its biorefinery and co-product brand LENZING™ Acetic Acid Biobased. The brand was first introduced on May 4, 1983, and has since become one of the leading and most trusted biobased acetic acid providers.

Over the past 40 years, LENZING™ Acetic Acid Biobased, which has a reduced carbon footprint that is 85% lower than that of fossil-based acetic acid, has continued to gain trust and support from customers. Specialty chemical company Evonik, and food production company Speyer & Grund Group, have been incorporating LENZING™ Acetic Acid Biobased in the production of their products since 1983. LENZING™ Acetic Acid Biobased has also been in high demand from the hygiene industry during the COVID-19 pandemic as an all-purpose cleaning agent in conventional and green products.

Pioneering a carbon neutral future in the biorefinery segment with a new offering
To mark the important occasion, Lenzing will introduce its first carbon neutral LENZING™ Acetic Acid Biobased to meet the growing sustainability needs of industries which predominately rely on fossil-based materials. Similar to the standard LENZING™ Acetic Acid Biobased, the carbon neutral LENZING™ Acetic Acid Biobased is produced using sustainably sourced beech wood as a universal replacement for non-renewable raw materials such as crude oil. By calculating, reducing and offsetting emissions during production processes, this expansion will create a more sustainable supply chain with highly functional products across various industries. From now on, Lenzing customers across the food, pharmaceutical, cosmetics, chemical and textile industries will be able to choose between carbon neutral and reduced carbon footprint acetic acid products.

Advancing circularity and carbon neutrality through efficient use of valuable resources
Lenzing’s biorefinery concept ensures that 100% of wood components are used to produce pulp for Lenzing’s botanic fibers, biorefinery products, as well as bioenergy, which is used to power Lenzing’s facilities. This makes Lenzing’s biorefinery sites almost fully energy self-sufficient to remain as carbon neutral as possible. To ensure a low carbon footprint, rail transportation is the preferred means for transporting LENZING™ biorefinery products, with trucks being leveraged in regions where rail transportation is not available.

Together with ClimatePartner, a recognized global leader in the design, development, and delivery of corporate climate action programs, Lenzing strives to reduce carbon emissions to net-zero through a mix of higher production efficiencies, use of renewable energy sources, low-carbon materials, and the dedicated support of an external nature-based carbon removal project. For instance, to offset remaining carbon emissions that cannot be reduced, Lenzing works with ClimatePartner to support and finance the switch to biomass as an energy source at a ceramic factory in Kitambar in northeastern Brazil. Using natural waste materials, like coconut shells, as renewable biomass for its energy production, the factory is able to produce roof tiles in a more climate-friendly way while saving on carbon emissions. Besides contributing to the fuel switch, the project also helps to reduce the deforestation rate in Brazil and avoid methane emissions that could result from the uncontrolled rotting of biomass.

• 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.

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.

Adient, a leading supplier of automotive seating systems, has achieved full ISCC PLUS (International Sustainability & Carbon Certification) of its foam plants in Lučenec (Slovakia) and Mandling (Austria) for increasing the sustainability of foams produced for its automotive seating systems. The stringent global sustainability certification system of ISCC allows for proven enhanced traceability of circular polyurethane (PU) foams throughout the supply chain.
 
The environmental impact of the newly developed PU formulations and processes of molded foams is improved by the re-integration of waste materials from industrial & natural origins replacing crude oil into the PU raw materials. This reduces the use of fossil-based materials in favor of recycled materials, to foster the development of a circular economy. As a result, the plants can offer foams with up to 20% less CO2 impact while fulfilling the same quality requirements as their conventional equivalents. To date, Adient is the first European ISCC PLUS certified PU foam manufacturer in this field.

Based on a mass balance approach, the certification highlights the need to envi-ronmentally balance every single stage of automotive value creation, including the entire supply chain.

This is how we live up to our claim as the ITA Group: sustainable - digital - individual."

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

Freudenberg Performance Materials (Freudenberg) is expanding its product portfolio by adding an elastic variant of its flexible superabsorbers for modern wound dressings. These superabsorbers increase the comfort level for patients as well as enabling longer wear time, thus reducing the frequency of dressing changes. Further highlights at EWMA include components for more sustainable wound care, PU foams with directly applied silicone adhesives, antimicrobial systems and an innovative hydrophilic debridement foam. The global manufacturer will be welcoming visitors to Exhibition Stand from May 3 – 5 at EWMA 2023.

Freudenberg uses a new technology to manufacture the elastic superabsorbers. Unlike other methods, this technology does not perforate or slit the material, thus achieving a high degree of consistent elasticity. Furthermore, the technology used by Freudenberg bonds the superabsorbent fibers more uniformly with the material, thus enhancing the integrity of this layer in the wound dressing.

Further highlights
Freudenberg is also presenting the M 1714 wound pad component, one example of a sustainable solution that simultaneously delivers on performance. The dressing consists of bio-based fibers and exhibits a smooth wound contact layer. M 1714 has been evaluated for industrial compostability and conforms to ISO 13432. This enables certification of product biodegradability. Further highlights to be presented in Milan include material systems for the antimicrobial treatment of chronic wounds, including systems that do not use active substances.

Wound dressing with silicone adhesive border
With Freudenberg’s silicone coated foams, manufacturers can reduce the number of process steps, thereby avoiding waste, saving energy and simplifying the supply chain. Compared with conventional foam dressings, the Freudenberg foam product also offers higher flexibility for optimal wound bed contouring and reduces the risk of infection by preventing exudate pooling. Freudenberg is showcasing the prototype of a bordered dressing with a silicone adhesive border. In addition, the variant with an extra-strong silicone border enables longer wear time while at the same time ensuring minimal adherence to new skin that forms at the wound edges.

More effective cleansing results and greater patient comfort
Freudenberg is also showcasing an innovative hydrophilic debridement foam. It is ideally suited for use in wound cavities, offers better cleansing results and reduced risk as well as greater patient comfort.

Groz-Beckert will be presenting the latest innovations from its product area Carding to visitors at INDEX™23

The InLine card clothing series for the nonwovens industry will take center stage at the Groz-Beckert exhibition booth. A new and patented manufacturing process made the development of the innovative metallic card clothing series possible. It offers customers improved process reliability and increased uptime of the card. At the same time, the new process enables environmentally friendly and resource-saving production.

In addition to a controlled and precise hardening of the teeth, the wires are characterized by a reduced rib height and a completely scale-free surface. An exhibit at the booth will demonstrate what distinguishes the new process from the conventional production method and will highlight the differences between the new Groz-Beckert InLine card clothing series and its predecessor generation.

The first special geometry of the Groz-Beckert InLine card clothing series to be developed was the SiroLock™ plus worker and doffer wire. It impresses with a more effective fiber take-up, control and transfer. Augmented reality will allow visitors to experience the functionality and operating principle behind SiroLock™ plus at INDEX™23.

From April 25^th to 27^th, 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.

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.
