From the Sector

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.

BTMA member Dent Instrumentation – a specialist in contactless yarn sensors – has become an employee-owned business following the formation of a new Employee Ownership Trust (EOT).

The company, based in Colne, Lancashire, has been family owned since its founder Geoffrey Dent secured a patent for the very first contactless yarn sensor in the 1960s. It has been successfully run by his son Andrew and the family for many years.
“This deal ensures a smooth succession as well as the preservation of the company’s core family values and the Dent Instrumentation name,” said Managing Director Colin Hull. “The EOT structure will maintain the integrity of the business for years to come.”

The liability of Dent sensors makes them integral to the yarn spinning and winding processes and they have become a standard throughout the textile industry, recognised for their quality, performance and value. They are used by major manufacturers of textiles and textile machinery under either Dent or OEM machine builder brands.

Monforts will take part in a VDMA textile technology trade delegation to Turkmenistan from November 21-26, on behalf of the German Federal Ministry of Economics.

Around 80% of Turkmenistan’s production of textiles and garments is currently exported, with a value of $350 million in 2020. This is now expected to rise to $450 million by 2023.

In addition to expanding in cotton yarns and fabrics, the country is also looking to enter other textile markets, including nonwovens, carpets and absorbent hygiene products, and negotiations are currently underway between the Turkmenistan Ministry of Textile Industry and the Korean Institute of Industrial Technologies to also commence manufacturing synthetic fibres from polymers.

In 2021, a new textile complex was opened by state-owned textile manufacturer Cotam in the city of Kaka, which is aiming to produce 3,650 tons of yarn, 12 million square metres of different types of fabrics and 1.2 million tons of finished products annually, with the creation of 1,300 new jobs.

Monforts has supplied seven complete finishing machine ranges to Turkmenistan company Cotam, as the Central Asian country looks to boost its production of cotton yarns and fabrics via an ambitious textile industry modernisation plan.

Cotam now has two separate manufacturing sites at Babadayhan and Kaka, both of which have now been equipped with Monforts technologies built at the company’s plant in St Stefan in Austria.

Cotam supplies finished fabrics to both the apparel and home textiles markets and at its Babadayhan plant is now operating two Montex stenter lines and a Monfortex sanforizing line. At its new Kaka plant, the company has also installed two Montex stenter lines, as well as a Thermex universal hotflue for continuous dyeing and curing.

“Turkmenistan celebrated 30 years of independence in 2021 and has made a giant leap forward in its progressive development,” said Monforts Managing Director Stefan Flöth. “A textile industry equipped with modern high-tech equipment has been created factories and equipped with the most advanced and high-performance equipment built and put into operation. We are extremely pleased that the Ministry of the Textile Industry of Turkmenistan chose Monforts machinery for its new textile complex in Kaka and together with the machines for Babadayhan and other recent projects we are proud to say that 15 Monforts machines are now established in the country.”

Rieter is presenting the latest innovations in its systems, components and services at the upcoming India ITME 2022 in Uttar Pradesh (India), taking place from December 8 – 13, 2022.

SSM is presenting NEO-FD, the assembly-winding machine for precision wound packages for twisting. It meets all requirements for efficient production. The machine features the auto-doffing option and the online back-pressure system for low and high package densities.

Temco CoolFlow Disc
Temco’s CoolFlow texturing discs offer longer lifetime thanks to a brand-new geometry and the latest polyurethane technology. The texturing discs now generate a disc surface that operates at a lower temperature, resulting in slower ageing and abrasion. Further benefits are more stable yarn quality, higher productivity, and an overall process cost reduction.

Freudenberg Performance Materials (Freudenberg) has concluded a high-volume, multi-year contract with a global automotive tier one supplier to supply high-performance gas diffusion layers for the stacks forming the core of the fuel cell systems produced by the leading automotive supplier. Global target applications are mid-sized and heavy commercial vehicles as well as buses. Freudenberg is supporting the customer’s global fuel cell activities, thereby also accelerating the breakthrough of mass-produced fuel cell stacks.

Fuel cell technology is an important element of a successful energy transition. Gas diffusion layers play a key role in this context: they are indispensable for the functioning of a fuel cell and have a significant impact on the performance of a fuel cell stack.

A fuel cell converts the chemical energy of hydrogen and atmospheric oxygen into electricity. Functionally-optimized gas diffusion layers made of carbon-fiber based nonwoven are installed on both sides of a catalyst-coated membrane positioned in the middle of the fuel cell. The gas diffusion layers distribute hydrogen and oxygen evenly to the membrane and remove the electricity, heat and water generated by the CO₂-free chemical reaction. They also protect the sensitive membrane and are optimized to suit the bipolar plate. A fuel cell stack is made up of several individual fuel cells.

Freudenberg already has more than 20 years of unique expertise in the development and production of gas diffusion layers for fuel cell applications in the mobility sector and for porous transport layers used in electrolyzers. Freudenberg is currently expanding its production capacity at its Weinheim headquarters by installing additional lines. Further investments are on the verge of implementation.

Long-standing BTMA member James Heal is celebrating its 150th anniversary this year, the company’s formation dating back to 1872, when it was listed as an oil and tallow merchant and mill furnisher in Yorkshire, UK.

Today, as a testing equipment manufacturer for textiles and nonwovens, James Heal continues to expand its range, with a focus on making testing simple – most notably with the introduction of its Performance Testing collection of instruments, most recently the AirPro and HydroView systems.

AirPro
The new James Heal AirPro air permeability tester is used to test the resistance of the flow of air through woven, knitted and nonwoven textiles. Its software offers flexibility with standards and  comprehensive reporting options and different test head sizes are available, making it suitable for a range of applications and standards

HydroView
The HydroView hydrostatic head tester is meanwhile designed to measure the penetration of water in materials which have an end use that requires water resistance, such as those in the medical, geotextiles and nonwovens sectors. It is also proving essential in the testing of end-use applications for technical textiles, such as in protective gloves, diving dry suits and winter sports apparel, to fishing waders, roofing, tenting, ground sheets and more.

RF5 SMMS 3200 nonwovens line is scheduled to be commissioned in the fourth quarter of 2022, and will be the first Reicofil 5 (RF5) line operating in Africa.

PFNonwovens is one of the most innovative nonwoven companies in the world, and continues to grow its footprint in the US, Europe and Africa. PFN wants to set a new benchmark of high-quality and innovative products for the Southern African markets with this purchase.

Markus Mueller, Sales Director of Reifenhäuser Reicofil and Key Account Manager for PFNonwovens, adds: “Since 2018, Reicofil has been delivering RF5 lines to support the global hygiene industry across four continents. The hygiene industry values the consistent product quality provided by RF5 and the key product performance properties it delivers at lower basis weights helping to drive industry sustainability goals. With an energy requirement of 1-1.2 kilowatt hours per kilogram produced, Reicofil 5 manages the conversion from raw material to nonwoven more efficiently than any other technology on the market. We are very pleased that after many years of partnership cooperation with PFNonwovens, we are now able to establish this technology at their South Africa location and look forward to our further collaboration to serve the hygiene and medical market in the whole region with top quality products.”

• Annual assembly of ACIMIT, the Association of Italian Textile Machinery Manufacturers

• Digitalization and Sustainability Key to Resiliency for Italian Textile Machinery Sector

The objective critical issues faced by Italy as a whole throughout the course of 2021, primarily dictated by a pandemic that upset any and all pre-existing equilibriums, have not slowed or halted the Italian textile machinery sector.

Indeed, data presented during the annual assembly of ACIMIT, the Association of Italian Textile Machinery Manufacturers, held on 1 July proved decidedly positive, showing that in 2021 the sector recovered significantly compared to 2020, to the point of returning to pre-Covid levels.

Specifically, Italian textile machinery production amounted to 2.388 billion euros (+35% over 2020 and + 5% over 2019), with total exports amounting to 2.031 billion euros (+37% over 2020 and +9% over 2019).

However, these results do not cancel the obstacles that companies are still facing. Looking to the near future, expectations are for a rather uncertain outlook, as underscored by ACIMIT President Alessandro Zucchi: “2022 remains a year replete with unknown factors, starting with the Russian-Ukrainian conflict, along with the persistence of the pandemic, which seriously risk delaying expected growth consolidation for businesses in the sector. Difficulties in finding raw materials and components negatively affect the completion and fulfilment of orders processed as far back as 2021. To boot, rising energy costs and inflationary trends affecting numerous commodities are depressing overall business confidence. So the outlook for the sector is not so good.”
As such, the two cornerstones through which ACIMIT aims to support the Italian textile machinery sector are digitilization and sustainability.

4.0: The textile machinery sector looks to the future
The road to digital transformation has already led numerous manufacturers to completely rethink their production processes, rendering them more efficient and l ess expensive. The digital world is moving ahead at a decisive rate in the textile machinery sector, where the buzzwords are increasingly, for instance, the Internet of Things connecting to a company’s ecosystem, machine learning algorithms applied to production, predictive maintenance, and the integrated cloud management of various production departments. It is no coincidence that ACIMIT has focused decisively on its Digital Ready project, through which Italian textile machinery that adopt a common set of data are certified, with the aim of facilitating integration with the operating systems of client companies (ERP, MES, CRM, etc.).

A green soul
Combining production efficiency and respect for the environment: a challenge ACIMIT has made its own and which it promotes among its members through the Sustainable Technologies project. Launched by the association as early as 2011, the project highlights the commitment of Italian textile machinery manufacturers in the area of sustainability. At the heart of the project is the Green Label, a form of certification specifically for Italian textile machinery which highlights its energy and environmental performance. An all-Italian seal of approval developed in collaboration with RINA, an international certification body.
The assembly held on 1 July provided an opportunity to take stock of the Sustainable Technologies project, more specifically, with the presentation of the Rina Consulting survey on the Green Label’s evolution and impact in recent years.

The results have confirmed the initiative’s extreme validity. The technological advances implemented by the association’s machinery producers participating in the project have effectively translated into benefits in terms of environmental impact (reduction of CO₂ equivalent emissions for machinery), as well as economic advantages for machinery users.

With reference to the year 2021, a total of 204,598 tons of CO₂ emissions avoided on an annual basis have been quantified, thanks to the implementation of improvements on machinery. This is a truly significant reduction which, for the sake of comparison, corresponds to the carbon dioxide emissions generated by 36,864 automobiles travelling an average of 35,000 km a year. In terms of energy savings, the use of green labeled textile machinery has provided excellent performances in allowing for a reduction of up to 84% in consumption.

A round table discussion on the Green Label’s primary purpose
The environmental and economic impact generated in production processes for Italian textile machinery through the use of Green Label technologies was the focus of the round table which concluded the ACIMIT assembly.

Moderated by Aurora Magni (professor of the Industrial Systems Sustainability course at the LIUC School of Engineering), the debate involved Gianluca Brenna (Lipomo Printing House administrator and Vice President of the Italian Fashion System for Welfare), Pietro Pin (Benetton Group consultant and President of UNI for the textile-clothing area), Giorgio Ravasio (Italy Country Manager for Vivienne Westwood), as well as ACIMIT President Alessandro Zucchi.

Called on to compare common factors in their experiences relating to environmental transition processes for their respective companies, the participants were unanimous: the future of Italian textile machinery can no longer ignore advanced technology developments capable of offering sustainable solutions with a low environmental impact while also reducing production costs. This philosophy has by now been consolidated, and has proven to lead directly to a circular economy outlook.

The upcoming ITMA 2023 exhibition
Lastly, a word on ITMA 2023, the most important international exhibition for textile machinery, to be held in Italy from 8 to 14 June 2023 at Fiera-Milano Rho. Marking the 19th edition of ITMA, this trade fair is an essential event for the entire industry worldwide, providing a global showcase for numerous innovative operational solutions on display. A marketplace that offers participants extraordinary business opportunities. The participation of Italian companies is managed by ACIMIT.

Monforts is introducing a range of modular upgrades that can be added to existing finishing lines already in production.

The Monforts universal Energy Tower – a flexible, free-standing air/air heat exchanger for recovering the heat from the exhaust air flow of thermal processes – can result in a 30% reduction in the energy consumed by a line, depending on the exhaust air volume and operating temperature.

A Monforts Eco Booster, completely integrated into the chamber design of the Montex stenter, is another retrofitting option. As a single state-of-the-art heat recovery system with automatic cleaning, it can be added to existing ranges. For ranges of up to eight chambers only one module is necessary to achieve significant energy savings.

On an eight-chamber stenter with an operating width of two metres carrying out a fixing process on a 150gsm woven fabric, for example, the energy savings have been calculated to be 35% over an annual schedule of 6,000 operating hours.

In addition, the Eco Booster consumes only minimal amounts of water during the cleaning cycle and the entire process is controlled and monitored automatically.

The Matex Eco Applicator is an alternative to the conventional padding process for energy-conscious finishing and achieving considerable savings in the energy required for drying treated fabrics. The precise amount of chemical can be applied to the fabric and with less residual moisture after application of only approximately 35% so that less drying capacity is required in the stenter, which leads to huge energy savings.

Finishes can be evenly applied on either or both sides of the fabric, and two separate treatments can be applied to front and back. This makes the unit ideal for the production of, for example, double-performance hydrophobic/hydrophilic fabrics for professional clothing, as well as the over dyeing or finishing of denim fabrics.

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Baldwin, a leading global manufacturer and supplier of precision spray systems and technology for sustainable textile manufacturing, announce a new collaboration to optimize performance and resource saving in the finishing department.

The two companies aim to support textile manufacturers in their development projects, targeting to improve their product safety, performance and functionality, while at the same time maximizing the productivity and resource utilization of the finishing application process.

Archroma and Baldwin are collaborating in multiple projects that combine Archroma’s most sustainable product innovations with Baldwin’s Texcoat G4.

TexCoat G4 is a non-contact spray technology for textile finishing and remoistening, designed to allow a controlled and optimal coverage of the exact amount of finish chemistry for reaching specific characteristics of the fabric. The system can be used to reduce water consumption by as much as 50% compared to traditional padding application processes.

Archroma and Baldwin are currently testing Archroma’s finishing products and systems, such as the soon-to-be-launched PFC-free* Smartrepel® Hydro SR for water-based soil repellence, as well as metal and inorganic particle-free antimicrobial technologies like Sanitized T 20-19 and TH 15-14, which will be launched at the upcoming Techtextil 2022.

The first test results will be available for discussions with both partners at Techtextil at their respective booths.
