• 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.

ITM 2022, which will be held at Istanbul Tüyap Fair and Congress Center on 14-18 June 2022, will be the first and largest international textile machinery exhibition to be held after a 3-year break. The leading brands of world textile technologies will launch their latest machines at ITM 2022.
The latest ITM Exhibition hosted the world textile industry with 1200 exhibitors from 64 countries and 60,000 visitors from 94 countries. ITM 2022 Exhibition in cooperation with TEMSAD and in partnership with Tüyap Tüm Fuarcılık Inc. and Teknik Exhibitions Inc. plans to set new records as one of the most important global organizations to be organized after the pandemic outbreak period.

The textile industry, which is among the leading sectors in Turkey's exports, demonstrated its power to the whole world, especially during the pandemic outbreak period. Achieving an increase of up to 40 percent in exports of textiles and raw materials, Turkey also broke records after records in medical textile, technical textile, and indoor textile exports.

Ranking in the top three in the most important market for the European textile machinery manufacturers, Turkey also attracted attention with its production performance during the troublesome pandemic outbreak. Many European machinery manufacturers, who spoke highly of Turkey's performance, announced that their machinery sales to Turkey increased in 2020 and 2021. Turkish textile companies, which increase their production capacity because they were unable to keep up with the demands, continue their new investments and modernizations.

Leading brands of textile technologies such as Picanol, Itema, Toyota, Saurer, Rieter and Trützschler are among the companies that will exhibit their latest innovations at the ITM 2022.

HIGHTEX International Technical Textiles and Nonwoven Trade Fair, which is planned to be held on June 22-26, 2021 was decided to postpone to June 14-18, 2022, considering the effects of the ongoing Covid-19 pandemic in the world. This postponement decision was taken as a result of intense discussions and evaluations with our participants and sector representatives.

The HIGHTEX Organization Team made the following statements: “We as HIGHTEX Organization Team, our priority is to protect your valuable exhibitors and visitors’ investments and all rights, not our commercial earnings. In this regard, we believe that all of our participants will find this compulsory postponement decision taken for the HIGTEX Exhibition justified and will understand.”

HIGHTEX 2022, which will be held in Istanbul Tuyap Fair and Congress Center between 14- 18 June 2022, simultaneously with the ITM 2022 Exhibition.

HIGHTEX 2022 being the first and only exhibition in its field in Turkey will host the world's leading technical textile and nonwoven manufacturers in Istanbul for 5 days.
HIGHTEX 2022, where many companies from Turkey and abroad will exhibit their latest technologies and products; will be visited by many industry professionals from medical to ready-to-wear, from decoration to cosmetics, from automotive to defense.

• ITM of TU Dresden – your research partner in the field of virtual product development at ISPO Munich
• ISPO Munich Online 2021 – the world´s leading sports business platform from February 1st to 5th 2021

The Chair of Assembly Technology for Textile Products of ITM presents itself for the first time at ISPO Munich Online 2021 – showcasing its expertise in the field of virtual product development. Its know-how in the determination of material parameters, digital data processing, and data transfer will be presented as well as its competencies in 3D/4D body shape recording via scanning, data animation for the 3D product development for functional clothing, and simulation for wear comfort/usage visualization. The Chair of Assembly Technology for Textile Products of ITM has manifested its leading global position in the virtual product development sector by successfully completing a variety of national and international interdisciplinary research projects.

Researchers of the Chair of Assembly Technology for Textile Products have been actively involved in the preparation and digital representation of material samples for the ISPO Textrends Forum. Thus, the material parameters of the ISPO Textrends Award textiles were determined for 3D fit simulations in Vidya (Assyst/Vizoo), automatically analyzed, and digitally processed by the specially developed "Material Analyzer" software. This software in addition to other state-of-the-art CAE infrastructure, such as the recently installed 4D Scanner Move4D, are essential for the further establishment and promotion of its leading position in the field of digitalization and virtual product development for garments for high-tech applications.

The researchers involved eagerly await future collaborations in this promising field of research. This pilot project presented at ISPO 2021 was coordinated by the company FOURSOURCE Group GmbH, thus enabling the characterization and 3D visualization of the award-winning materials that are presented to all visitors at ISPO 2021.

A Move4D scanner is the latest addition to the state-of-the-art CAE infrastructure at the Chair of Assembly Technology for Textile Products at the ITM – this comes as an early Christmas surprise that has been eagerly awaited by the researchers. The high-speed 4D scanner was developed at the IBV - Instituto de Biomecánica, Spain, and will be a valuable tool for future research projects involving interactions of humans and their clothing. Professor Yordan Kyosev, Head of the Chair of Assembly Technology for Textile Products, is just as excited as his team of researchers about the arrival of the new Move4D scanner. “By means of this scanner, we will be able to strengthen and extend our leading global position in digitalization and virtual product development for tight clothing in high-tech applications,” says Professor Kyosev who is looking forward to new co-operations in this promising field of research.

This high-speed scanner is able to capture an entire body with 180 Hz and a precision of < 1mm, thus guaranteeing the precise analysis of interactions between body and textile as well as deformation during motion. The Move4D can record and analyze dynamic processes at a very high speed. Hence, this device will enable researchers to make significant contributions towards enhanced functional (e.g. for the sports and medical sector) and protective clothing.

Together with three already available 3D scanners, this high-speed 4D scanner represents Dresden´s new „3D&4D Scan Lab“ at the Chair of Assembly Technology for Textile Products for the static and dynamic recording of small and medium-sized objects. Professor Kyosev and his team of 17 researchers are among the world´s leading R&D experts for clothing and technical products who will continue to expand their expertise in the field of material modelling for textile materials.

The ITM 2021 Exhibition, which is postponed to 22-26 June 2021 due to the coronavirus pandemic outbreak, will direct the world and Turkish textile industry, which will demonstrate a vigorous comeback in the post-pandemic period.

The ITM Exhibition, which was planned to be held between 2-6 June this year, was postponed to 22-26 June 2021 due to the troublesome Coronavirus pandemic. Participating companies in countries that had to interrupt their production, especially Italy, France, Spain, Germany and China, which were most affected by the virus, welcomed the postponement of the ITM Exhibition. The countries, holding similar opinions that it is not possible to save from the pandemic without effective drug treatment or vaccine against coronavirus, started normalization process by increasing their protective measures while fighting against the pandemic.

The Mechanical Engineering Industry Association (VDMA) has awarded two prizes to graduates of the Institut für Textiltechnik (ITA) of RWTH Aachen University - the dissertation prize and the creativity prize of the Walter Reiners Foundation of German Textile Machinery 2018. ITA alumnus Dr Benjamin Weise was awarded the dissertation prize for the development of novel fibres for textile charge storage devices. For their work on a guide to 4D product design, Jan Merlin Abram and Aalon Tal (both ITA students) were honoured with the creativity prize. The dissertation prize is endowed with €5,000 whilst the creativity prize contains a one-year scholarship of €250 per month. Peter D. Dornier, President of the Walter Reiners Foundation and Chairman of the Management Board of Lindauer DORNIER, presented the awards on the 18 September 2018 at the 18th Textile Machinery Forum in the Digital Capability Center in Aachen, Germany.

Graphene revolutionizes all-in-one - supercaps, reduction of terahertz radiation and antistatics

In his dissertation "Development of graphene-modified multifilament yarns for the production of textile charge storage devices", laureate Dr Benjamin Weise developed novel fibres made of polyamide and graphene and further processed them into textile surfaces. The newly developed polyamide graphene fibres are featuring a multitude of advantages:

• Due to their high performance in the charge storage area, they are predestined for use in double-layer capacitors, so-called super capacitors, or supercaps in short. Compared to lithium-ion batteries, supercaps offer significantly higher power density and a longer lifetime as no chemical reactions are taking place. towing to the graphene platelets in the filaments, it is now possible for the first time to integrate a charge storage device directly into a textile without having to sew in a rechargeable battery. This new fibre is therefore suitable for prospective use in smart textiles, for instance in a textile defibrillator.
• The new graphene-modified polyamide fibres can attenuate inident terahertz radiation up to 25 % of their original intensity. Terahertz radiation, for example, offers transmission rates of 100 Mbit/sec and is therefore of high interest for high-performance wireless communication. However, the radiation could damage sensible electronics as in aircrafts if this technology will be used widespread. Consequently, the shielding of the radiation is of high importance, e.g. in the form of fibre composite components in the aircraft, which protect the on-board electronics.
• As the fibres are showcasing a dissipative electrical conductivity, personal protective equipment is another prospective field of application.  

The development of a pilot process for graphene-modified fibres and the production of textile demonstrators are novel and disruptive attainments of Dr Weise’s PhD thesis and the reason for the award ceremony to him. Due to its outstanding properties, the European Union is funding research on graphene within the frame of the "Graphene Flagship" with an overall budget of one billion Euro (source: http://graphene-flagship.eu/project/Pages/About-Graphene-Flagship.aspx).

Modular product design of 4D products is now possible in simplified form

How can three-dimensional products change their shape over time and thus become "four-dimensional"? The students Jan Merlin Abram and Aalon Tal provide answers to this question in their project work "Leitfaden zur Auslegung hybrider morphender Textilien am Beispiel eines Scharniers" (Guidelines for the Design of Hybrid Morphing Textiles Using the Example of a Hinge), for which they were awarded the creativity prize. In their work, the students offer a guideline for the development of a four-dimensional textile from the idea to the demonstrator. Four-dimensional textiles, for example, consist of a hybrid material of elastic textile on which three-dimensional structures are printed. The fourth dimension describes the change in shape and/or a property over a defined period of time (= morphing).  This change is caused by external influences such as light and heat.

Every year, the Foundation of the German Textile Machinery awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the smartest student research project. Further prizes were awarded to Eric Otto, ITM Dresden, and Susanne Fischer, Reutlingen University.

Das ITM wird den Besuchern der JEC einen umfassenden Einblick in die aktuellen Arbeiten auf dem Gebiet der Maschinen- und Produktentwicklungen entlang der gesamten textilen Prozesskette geben.
Ein Highlight auf der JEC 2018 ist die Präsentation der vielfältigen Möglichkeiten, die die Struktur- und Prozesssimulation textiler Hochleistungswerkstoffe und textiler Fertigungsprozesse bietet.

Mittels skalenübergreifender Modellierung und Simulation wird am ITM ein tiefgreifendes Material- und Prozessverständnis erreicht. Dazu wurden Finite-Element-Modelle auf der Mikro-, Meso- und Makroskala entwickelt und validiert. Beispiele aus aktuellen Forschungsprojekten des ITM demonstrieren die vielseitigen Möglichkeiten und Einsatzbereiche der modernen Simulationsmethoden auf dem Gebiet der Textilmaschinen.

Weiterhin werden beispielhafte innovative konstruktive Highlights aus dem Bereich der Flachstricktechnologie durch das ITM vorgestellt. Eine besondere Herausforderung bei der Verwendung von Faserkunststoffverbunden (FKV) mit komplexen Freiformflächen ist neben der belastungsgerechten Auslegung eine wirtschaftliche und produktive Fertigung, wofür am ITM innovative, hochdrapierbare und anforderungsgerechte textile Halbzeuge entwickelt werden. Konstruktive Neu- und Weiterentwicklungen im Bereich Textilmaschinen erfolgen dabei in enger Zusammenarbeit mit namenhaften Textilmaschinenherstellern, wie u.a. Stoll, Steiger und Shima Seiki.  

Im Rahmen einer Projektbearbeitung konnte am ITM ein innovatives Verfahren für die kontinuierliche und damit hochproduktive Fertigung von komplexen, schalenförmigen und hohlprofilförmigen 3D-Preforms aus Hochleistungsfaserstoffen entwickelt und erfolgreich umgesetzt werden. Durch die prozessintegrierte Strukturfixierung eignen sich die Preforms hervorragend für die Weiterverarbeitung zu FKV-Bauteilen. Hierbei arbeitet das neue Umformverfahren ohne aufwändige, bewegte bzw. aktiv angetriebene Elemente. Daher ist die Ausformung komplexer Geometrien bei engen Bauraumsituationen besonders gut zu realisieren. Damit gelingt erstmals die kontinuierliche und reproduzierbare Herstellung geschlossener hohlprofilförmiger 3D-Preforms mit sehr guter und reproduzierbarer Qualität, die zur JEC ausgestellt werden.

Ein am ITM erfolgreich etablierter Entwicklungsschwerpunkt sind 3D-Strukturen in Form von Near Net Shape Preformen, die zur JEC präsentiert werden. Dazu gehören z.B. ebene und gekrümmte Bauteile mit integrierten Rippen für die Steigerung der Biegesteifigkeit von hoch tragenden Bauteilen, die am ITM kontinuierlich in einem simulationsgestützten Verarbeitungsprozess gefertigt werden. Eine besondere Herausforderung ist die Entwicklung von dringend benötigten anforderungsgerechten Knotenverbindungselementen aus Glas- und Carbon-Filamentgarnen, die mittels hochkomplexer simulationsgestützter Bindungskonstruktionen auf modernsten computergesteuerten Textilmaschinen am ITM hergestellt werden. Für diese Entwicklungen wurde das ITM mehrfach international ausgezeichnet.

Zum Thema Multimaterialcomposites auf Basis von textilen Halbzeugen und Metallblech werden Ergebnisse anhand von Technologiedemonstratoren offeriert, die im Rahmen interdisziplinärer und institutsübergreifender Forschung entlang der gesamten Prozesskette erfolgreich umgesetzt wurden. Im Rahmen mehrerer Forschungsprojekte wurde eine Prozesskette entwickelt, die eine kostengünstige und großserientaugliche Bauteilfertigung von FKV-Metallblech-Verbunden durch in-Situ-Umfom-Fügen aus den Halbzeugen erlaubt.  

Auf der JEC stellt das ITM auch exemplarische Demonstratorstrukturen wie Near Net Shape Preforms und textile Bewehrungen für Carbonbetonanwendungen vor, die mittels der am ITM fest etablierten Multiaxial-Kettenwirktechnologie, gefertigt worden sind. Durch eigene Weiterentwicklungen beim individuellen Kettfadenzulieferungs, -versatz und abzugssystem, bei der Fertigung thermoplastischer Hybridspreizbänder sowie bei dem online-Beschichtungssystem für textile Bewehrungen können maßgeschneiderte Halbzeuge hergestellt und neue Anwendungsfelder erschlossen werden.  

Weiterhin wird am ITM die Entwicklung und Umsetzung von neuartigen Garnkonstruktionen aus recycelten Carbonfasern (rCF) für neue Verbundwerkstoffe erfolgreich vorangetrieben. Mit einer sogenannten Spezialkrempelanlage werden recycelten Fasern aufgelöst, vereinzelt und zu einem breiten gleichmäßigen Band zusammengeführt. Anschließend können daraus auf Basis verschiedener Spinntechnologien neuartige Hybridgarnkonstruktionen aus gleichmäßig vermischten recycelten Carbon- und Thermoplastfasern gefertigt werden. Ausgewählte Garnkonstruktionen und daraus gefertige Demonstratoren werden den Besuchern zur JEC präsentiert.
