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.

In the run-up to ITMA, VDMA is presenting an overview of the textile recycling technologies offered by member companies exhibiting at ITMA. VDMA and its members are committed to a responsible use of all resources used in textile production.

As a global provider of sustainable woodfibre products, Sappi will be showcasing its solutions for the garment industry under the theme “Fashion meets Forest” at ITMA 2023 – with sublimation papers and its dissolving wood pulp, used for the production of garment fibres under the “Verve” brand name.

How can the woodfibre industry support a more sustainable garments market? Sappi is eager to answer this question at the ITMA and has created a “knowledge trail” for visitors to explore under the motto “Fashion meets Forest”. Visitors to the stand can follow the journey from wood via cellulose and fibre to the finished yarn and the printed garment.

Sublimation papers: Expanded production capacity in Carmignano
Sappi’s Transjet sublimation papers stand for fast, uniform ink transfer and minimal ink consumption. As a premium supplier, Sappi is constantly striving to meet its customers’ needs. So, at this year’s ITMA, various sublimation papers with optimised qualitative properties will be on show.

Sappi maintains the high quality of its coated Transjet and uncoated Basejet sublimation papers by regularly investing in new, state-of-the-art technologies. At the end of April, a new warehouse has been inaugurated at the Carmignano mill in Italy. In the next month’s, Sappi will further invest in two new converting machines with a width of 1.9 meters and 3.2 meters as well as in a fully automated packaging line. All the investments will support the company’s vision of having a complete in-house solution for the sublimation industry, have a positive impact on CO2 emission, satisfy the increased demand of their customers as well as further improve lead times.
 
“Verve” dissolving wood pulp for high-quality textiles
Sappi will also be showcasing its dissolving pulp (DP) brand “Verve”. DP provides the feedstock raw material toward producing rayon fibres such as Lyocell and viscose and further into yarns and fabrics. Textiles produced from wood based cellulosic fibres are noted for their breathability, colour fastness, softness, drape, absorbency and biodegradability. In addition to the garment industry, dissolving pulp is also used in various household and pharmaceutical products.

At ITMA 2023, XORELLA, a specialist in steam setting and conditioning equipment for yarns and fabrics, will launch XO AUTOMATION for the double door XO SELECT conditioning machine series, and XO SOLID, a new machine series to complement XO SMART, XO TREND and XO SELECT machines.

XO AUTOMATION
The new XO AUTOMATION system consists of roller conveyor systems for loading and unloading two-door XO Select conditioning machines. Additional pallet wrapping machine with a turntable, weighting station, label printer, safety fence and security system can complete the system. The XO Select controller and automation system can handle and store individual customer-specific material and packing programmes.  

XO SELECT and XO AUTOMATION are designed for yarn steaming on multiple pallet dimensions and heights up to 2,650mm. The linear material flow passing conveyor and steaming machine avoids any mix between steamed and un-steamed materials. XO AUTOMATION fills the gap between the XO automated moving platform and the fully automated transport system – from spinning hall to warehouse.

XO SOLID
The new cubical XO SOLID combines a high loading space of 1,800mm x 1,700mm x 4, 000mm (H x W x L) through double row pin trolleys or pallets for easy manual loading of six units on floor level without a pit or platform. XO SOLID is therefore designed for installations on upper floor levels. The new frame design combines all necessary components factory preinstalled on a single frame, for easy ‘plug and play’ installation at the customer site. Additional smaller steamer dimensions for two and four loading units are also at the planning stage.

The new XO SOLID incorporates all the renowned features of XORELLA machines based on the long term experience in high temperature dyeing vessel production of FONG’s, including:

• A Siemens controller with OPC UA interface and XO data tool for batch storage.
• A XO EcoPac waterless claw pump or two-stage water ring vacuum pump.
• A high energy efficient accumulator for steam, electric and combined heating.
• Vessel and piping in world-class stainless steel.
• European key components such as pumps, heating elements, valves and sensors

Established in Switzerland in 1967, XORELLA became known in the global textile industry for its innovative indirect steaming system. Since 2002 the company has been a member of the CHTC Fong’s International Group, and a member of SINOMACH Group (China National Machinery Industry Corporation) since 2019.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK will be exhibiting at ITMA 2023, taking place between 8-14 June Milan, Italy. FET has commissioned its biggest ever stand to reflect the company’s commitment to this event and the textile industry.

FET designs, develops and manufactures extrusion equipment for a wide range of high value textile material applications worldwide. Central to FET’s success has always been its ability to provide customers with advanced facilities and equipment, together with unrivalled knowledge and expertise in research and production techniques.

The new FET Fibre Development Centre will further improve this service, allowing clients to trial their own products in an ideal environment. Resident equipment in the Fibre Development Centre reflects the wide range of fibre extrusion systems offered by FET to clients worldwide and will enable continued growth of the company through innovation.  

For the first time at ITMA, the new FET Spunbond range will feature. This system provides opportunities for the scaled development of new nonwoven fabrics based on a wide range of fibres and polymers, including bicomponents. Recent customers to benefit from FET spunbond systems include the University of Leeds and an integrated metlblown / spunbond system at the University of Erlangen-Nuremberg in Germany.

FET’s established expertise remains in laboratory and pilot meltspinning equipment for a vast range of applications, such as precursor materials used in high value technical textiles, sportswear, medical devices and specialised novel fibres from exotic and difficult to process polymers. FET has successfully processed almost 30 different polymer types in multifilament, monofilament and non-woven formats, collaborating with specialist companies worldwide to promote greater sustainability through innovative manufacturing processes. Where melt spinning solutions are not suitable, FET provides a viable alternative with pilot and small scale production wet spinning systems.

A major theme at ITMA will again be sustainability. The FET range of laboratory and pilot extrusion lines is ideally suited for both process and end product development of sustainable materials. “This year we are celebrating FET’s 25th anniversary” says FET Managing Director Richard Slack “and we look forward to meeting customers at ITMA, where we can discuss their fibre technology needs.”

At ITMA 2023 in Milan from June 8-14 this year, Monforts is organising two free-to-attend seminars and discussions on the potential of green hydrogen as a new energy source for textile finishing, drying and related processes.

Monforts is currently leading a consortium of industrial partners and universities in the three-year WasserSTOFF project, launched in November 2022, that is exploring all aspects of this exciting and fast-rising new industrial energy option.
The target of the government-funded project is to establish to what extent hydrogen can be used in the future as an alternative heating source for textile finishing processes. This will first involve tests on laboratory equipment together with associated partners and the results will then be transferred to a stenter frame at the Monforts Advanced Technology Center (ATC).

To be considered “green”, hydrogen must be produced using a zero-carbon process that is powered by renewable energy sources such as wind or solar. Currently, the cleanest method of hydrogen production is electrolysis, using an electrically-powered electrolyzer to separate water molecules into hydrogen and oxygen. The purity of the hydrogen is also important, and impurities must be removed via a separation process.

“Despite all its advantages, there are obstacles to overcome on the way to widespread, economically-feasible green hydrogen use,” explains Monforts Textile Technologies Engineer Jonas Beisel. “Until there are widely available, reliable and economical sources of this clean power, the cost of producing it will remain prohibitive. The infrastructure is not yet there, and hydrogen also has a tendency to make steel brittle and subject to fracture, which is something that requires further investigation in both its transportation and use in industrial processing.
“Green energy’s potential as a clean fuel source is tremendous, but there is much we need to explore when considering its use in the textile finishing processes carried out globally on our industry-leading Montex stenter dryers and other machines.”

At its Advanced Technology Center (ATC) in Mönchengladbach, Monforts will be carrying out intensive tests and trials to assess the reliability of both processes and final products when different natural gas and hydrogen mixtures – up to 100% green hydrogen – are employed. The results will be closely analysed by the consortium partners because there are many parameters that at this stage remain unknown.

The aim, Beisel adds, is to both reduce CO₂ emissions and – following the rising prices and industry turbulence experienced by manufacturers over the past year or so – to further reduce a dependency on natural gas.

The three-year WasserSTOFF project is sponsored by Germany’s Federal Ministry for Economic Affairs and Climate Action, and with Monforts at the helm brings together industrial partners Pleva and NTB Nova Textil, with academic input from the Hochschule Niederrhein and the Technical University of Freiberg.

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

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.
