From the Sector

Die Verleihung der Förder- und Kreativitätspreise 2021 der Walter Reiners-Stiftung des VDMA, Fachverband Textilmaschinen an Studierende und Nachwuchswissenschaftler:innen deutscher Universitäten für Spitzenleistungen in Studium und Promotion fand am 09. November 2021 im Rahmen der Aachen-Dresden-Denkendorf International Textile Conference 2021 statt. Die bundesweit ausgeschriebenen Förder- und Kreativitätspreise wurden erneut online durch Herrn Peter D. Dornier, Vorstandsvorsitzender der Walter Reiners-Stiftung, verliehen.

Dr.-Ing. Martin Hengstermann wurde mit dem mit 5.000 EUR dotierten Förderpreis beste Dissertation des Deutschen Textilmaschinenbaues 2021 für seine am Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik der TU Dresden erarbeiteten Dissertation „Entwicklung von Hybridgarnen aus recycelten Carbonfasern und Polyamid 6-Fasern für thermoplastische Verbundbauteile mit hohem Leistungsvermögen“ geehrt.

Gegenstand der Dissertation ist die Entwicklung und Umsetzung von neuartigen Hybridgarnen aus recycelten Carbonfasern (rCF) und Polyamid (PA) 6-Fasern für thermoplastische Verbundbauteile. Diese Hybridgarne können die hervorragenden mechanischen Eigenschaften der rCF im Gegensatz zu bisherigen Lösungen in hohem Maße ausnutzen. Bedingt durch deren spezielle Fasereigenschaften (insbesondere hohe Querkraftempfindlichkeit, Sprödigkeit und fehlende Kräuselung) wurde dafür die Prozesskette der konventionellen Stapelfasergarnherstellung, bestehend aus Krempel, Strecke und Flyer, umfangreich analysiert und technologisch-konstruktiv weiterentwickelt, wodurch erstmalig eine schonende und gleichmäßige Herstellung der Hybridgarne ermöglicht werden konnte.

Picanol has introduced its latest generation of airjet and rapier weaving machines, which have been called the “Connect” generation. These new generation weaving machines focus on connectivity and an increased level of data availability. With this new generation, Picanol is launching several new functionalities such as a digitalized Gripper stroke setting, Gripper tape monitoring, Climate control, Shed angle measurement, and fully integrated Power monitoring.

“Following the successful launch of our digital platform PicConnect earlier this month, we have now released a new generation of weaving machines, which are known as the Connect generation. Our Connect generation weaving machines can provide the correct data and are loaded with new and never-before-seen functionalities. This is clear proof that for Picanol “Driven by Data” is not just a slogan but a commitment. Not only have these innovations allowed us to make big improvements when it comes to our four design principles – Smart Performance, Sustainability Inside, Intuitive Control, and, of course, Driven by Data – but when combined with our new digital platform they will allow you to amplify your own intuition.” comments Johan Verstraete, Vice President Weaving Machines.

From now on, the range of Picanol weaving machines will have the “Connect” suffix. For the airjet weaving machines, this means: OmniPlus-i Connect and TerryPlus-i Connect, while for the rapier weaving machines, this means: OptiMax-i Connect and TerryMax-i Connect. These new machines are built around Picanol’s four main design principles:

Smart Performance
On the OptiMax-i Connect, Picanol has introduced a lubrication monitoring sensor in combination with a temperature sensor. The combined data they provide allow the user to make sure the gripper tapes are in optimal condition for maximum performance. As an option, a gripper stroke measurement sensor is also available. This not only dramatically simplifies the setting of the gripper stroke, but also enables the user to realize higher machine speeds when weaving reduced widths – a pure extra output combined with more user-friendliness.

Sustainability Inside
Even though it was 25 years ago that the Sumo Drive concept was launched, it remains the most powerful, versatile and energy friendly machine drive available. And it has been even further optimized. It features an optimized sheet metal package for lower energy consumption, optimized oil cooling circuit for a better performance and a built-in temperature monitoring. Moreover, the Connect machines can be equipped with a Power monitoring module, which allows the user to keep track of the power consumption of each machine over time. Every Connect machine also has a built-in ambient temperature and humidity sensor, which will help to optimize the climate control in the weaving shed at the lowest cost. And as raw material is the biggest cost factor, each machine can also be equipped with raw material use monitoring.

Driven by Data
As the machine has more sensors than ever before, it also generates more data. To enable a fast reaction to all these sensor data, the BlueBox control unit has been further optimized: better heat management guarantees short reaction cycles combined with the long lifetime of components. To have a good view of all of the data generated, a special sensor dashboard screen is available in the BlueTouch display: with a simple touch of the screen, the current and historical power consumption, temperature, humidity, material consumption, and – on the OmniPlus-i Connect – also the air consumption, can be monitored. The BlueTouch display is now also equipped with an Action center, an electronic logbook where all actions such as maintenance interventions can be logged or scheduled beforehand. The machine manual is now available on the BlueTouch display, and with the context-based help function the help pages related to the operation the user wants to perform appear with one touch of his/her fingertip. The built-in web browser even allows the user even to consult, for example, tutorial videos on the web to guide them through a setting procedure.

Intuitive Control
The Connect generation was designed to focus on what really matters: weave the highest possible grade A fabrics at minimal costs. A large set of tools have been installed to facilitate this goal. One of the most remarkable ones is the Harness frame stroke measurement – until recently, it was only available on the revolutionary SmartShed, but it is now also available on the cambox and dobby machines. Combined with the shed visualization and simulation, it offers a quantum leap in terms of optimizing the user’s shed settings without losing any time or taking any risks. The colors of the programmable Smart signal lights with stop timing functionality are now repeated around the push buttons, allowing even better visibility and the prioritization of interventions by the weaver. A full-fledged Access control system not only limits the access to certain pages and settings depending on the user, but also allows a tailored dashboard to be established for each user profile.

Im Rahmen eines Workshops der „RUDOLSTÄDTER KUNSTSTOFFTAGE“ stellte das Thüringische Institut für Textil- und Kunststoff-Forschung e.V. (TITK) am 4. November 2021 eine wichtige Neuinvestition vor: eine Anlage für den pulverbasierten 3D-Druck. Damit können die Forschungsaktivitäten auf dem Gebiet der Additiven Fertigung deutlich ausgebaut werden. Das Druckzentrum kostete knapp 250.000 Euro und wurde dank des Thüringer Corona-Sonderförderprogramms „FuE-Schub“ für wirtschaftsnahe Forschungseinrichtungen möglich.

Das am TITK ansässige 3D-Druck-Kompetenzzentrum Rudolstadt arbeitete bisher nur mit dem sogenannten FDM- bzw. FFF-Verfahren. Die Abkürzungen stehen für Fused Deposition Modeling bzw. Fused Filament Fabrication und beschreiben die schichtweise Herstellung eines Werkstücks aus einem schmelzfähigen Kunststoff. Dieser wird als Endlosfaden zugeführt. „Ausgehend von unserer Historie und der langjährigen textilen Kompetenz unseres Hauses haben wir zunächst nur Filamente für den 3D-Druck genutzt und erforscht“, erläutert Patrick Rhein, Leiter der Forschungsgruppe Additive Fertigung. „Mit der Anlage zum selektiven Lasersintern ist es uns jetzt möglich, auch thermoplastische Pulver einzusetzen und weiterzuentwickeln.“

Im Gegensatz zum filamentbasierten 3D-Druck nach FDM- bzw. FFF-Verfahren wird beim selektiven Lasersintern (SLS) ein Pulverbett angelegt und erhitzt. Laserstrahlen verschmelzen bzw. sintern das Material dann hochgenau und ebenfalls Schicht für Schicht. Da immer wieder ein neues Pulverbett darüber aufgetragen wird, sind hierbei keine zusätzlichen Stützmaterialien nötig, die man anschließend wieder herauslösen müsste. „Außerdem ist die Festigkeit der Produkte deutlich höher, sie können gleichmäßig Zugkräfte in alle Richtungen aufnehmen“, sagt Projektingenieur Henning Austmann.

In Sachen 3D-Druck kehrt damit endgültig Industriestandard am TITK ein, der sich nicht nur zur Prototypenentwicklung, sondern auch für den Nachweis einer Prozessfähigkeit eignet. Mit der SLS-Anlage lassen sich Teile mit einer Kantenlänge von bis zu 45 Zentimetern herstellen. Zudem werden technisch relevantere Werkstoffe verarbeitet, so etwa Polypropylen (PP), Polyamid (PA) oder Thermoplastische Polyurethane (TPU), während man vom filamentbasierten Druck vor allem amorphe Werkstoffe wie ABS und PLA kennt.

„Mit der neuen SLS-Anlage können wir unsere Arbeit nun thematisch erweitern“, sagt Teamleiter Patrick Rhein. Das Pulverdruck-Verfahren brauche zwar in der Regel eine längere Vorbereitung, sei aber letztlich deutlich schneller. Zudem handele es sich beim Druckzentrum am TITK um eine offene Anlage, das heißt sämtliche Parameter können selbst bestimmt und voreingestellt werden. „So haben wir alle Möglichkeiten, um gemeinsam mit Partnern aus Industrie und Wissenschaft neue Materialien zu entwickeln und zu erproben“, freut sich Rhein. Denn das Angebot an Ausgangsstoffen für das Pulverdruckverfahren sei aktuell noch recht überschaubar. In Forschungskooperationen sollen nun beispielsweise Zusatzstoffe für Pulverisierungsverfahren getestet werden, um bei der additiven Fertigung etwa eine höhere Wärme- oder elektrische Leitfähigkeit sowie Flammschutz oder verbesserte Steifigkeit zu erzielen.

Passend zu den neuen technischen Möglichkeiten am TITK stellte am 4. November auch der Workshop die Vor- und Nachteile von filamentbasiertem und pulverbasiertem 3D-Druck gegenüber. Mit an Bord waren diesmal renommierte Maschinenhersteller, Materialanbieter, Forschungseinrichtungen sowie Anwender aus der Industrie, die in acht Vorträgen die neuesten Entwicklungen aus der Branche vermittelten.

Members of TMAS – the Swedish textile machinery association – are proving instrumental in pioneering new sustainable processes for the dyeing, finishing and decoration of textiles.

The wasteful processes involved in these manufacturing stages are only one component in the development of viable circular supply chains for textiles that are now being established in Sweden.

At the recent Conference on Sustainable Finishing of Textiles, held across three separate afternoons on September 30^th, October 1^st and October 7^th, delegates heard that Sweden will introduce extended producer responsibility (EPR) for waste textiles and clothing at the beginning of 2022, ahead of the adoption of a similar European Union-wide EPR system in 2025.

New fibers
Swedish companies are also active in the development of new fibers derived from waste clothing, building on the country’s legacy leadership in pulp and paper production.

At the Sustainable Finishing of Textiles Conference, however, it was said that all of the environmental gains made by such sustainable new fibers can potentially be cancelled out in the further processing they are subjected to – and especially in resource-intensive conventional dyeing, finishing and decoration.

TMAS members Baldwin Technology and Coloreel have both developed solutions to address this issue.

TexCoat G4
During the conference, Baldwin’s VP of Global Business Development Rick Stanford explained that his company’s TexCoat G4 non-contact spray technology significantly reduces water, chemistry and energy consumption in the finishing process. It consistently and uniformly sprays chemistry across a fabric surface and applies it only where needed, on one or both sides.

Instant coloring
Coloreel’s CEO Mattias Nordin outlined the benefits of his company’s technology which enables the high-quality and instant coloring of a textile thread on-demand and can be paired with any existing embroidery machine without modification. This enables unique effects like shades and gradient to be achieved in an embroidery for the first time.

• Order intake of CHF 698.6 million in third quarter 2021
• Order intake of CHF 1 673.9 million after nine months
• Acquisition of the three Saurer businesses on schedule
• Credit lines renewed early
• Outlook 2021

The positive market dynamics, which Rieter has already reported on several occasions, continued in the third quarter of the current year. Rieter recorded an order intake of CHF 698.6 million in the third quarter of 2021 (2020: CHF 174.4 million).

The order intake of CHF 1 673.9 million after nine months corresponds to an increase of 294% compared to the prior year period (2020: CHF 425.1 million).
 
The market development is broadly supported at the global level and is based on a catch-up effect from 2019 and 2020 in combination with a regional shift in demand. Rieter believes that a major reason for this regional shift in demand is the development of costs in China. This is leading to increased investments outside the Chinese market. The orders came primarily from Turkey, Latin America, India, Pakistan and China. Overall, Rieter is benefitting from its innovative product range and the global positioning of the company.

The Business Group Machines & Systems achieved an order intake totaling CHF 1 281.6 million in the first nine months of 2021 (+447%).*

In the first nine months of 2021, the Business Group Components recorded an increase of 95% to CHF 227.0 million, while the Business Group After Sales posted an order intake of CHF 165.3 million, an increase of 123% compared to the prior year period.*

Acquisition of the three Saurer businesses on schedule
The acquisition of the three businesses from Saurer, which Rieter announced on August 16, 2021, is proceeding according to plan. The incoming orders for these businesses are not taken into account in this trading update.
 
Credit lines renewed early
The Rieter Group arranged the early renewal of the existing committed credit lines (five-year term, totaling CHF 250 million).
 
Outlook 2021*
The first nine months of 2021 were characterized by a rapid market recovery combined with a regional shift in demand. Rieter expects the demand for new systems to gradually return to normal in the coming months.  
 
For the full year 2021, Rieter anticipates sales of around CHF 900 million.

Knopf’s Sohn, a contract finisher of technical textiles, has installed a fully automated Montex stenter at its plant in Helmbrechts, Germany.
Knopf’s Sohn is processing technical textiles for the automotive, aerospace, home furnishings and workwear markets, based on wool, cellulose, polyamide and polyester fabrics, along with elastane blends, in weights of 80-800gsm.

The Montex machinery range is constantly being upgraded to meet evolving customer needs for greater automation, ease of operation and energy optimisation. The latest ten chamber line at Knopf’s Sohn, with a working width of up to 2.0 metres, was engineered to specific requirements in order to accelerate the company’s move to fully automatic control of its production, and high scaffolding was required for its installation.

The line benefits from two integrated ECO Booster modules to provide high energy savings. These compact, air-to-air heat exchangers, installed within the roof structure of the line, exploit energy from the exhaust gas to preheat up to 60% of the incoming fresh air entering the stenter.

The use of a single ECO Booster unit has been calculated to save up to 35% in energy costs, based on fixation processes. Fully automatic operation, set at the Monforts Qualitex control unit, ensures there is no additional burden on the machine operator.

The line is powered by Exxotherm indirect heating, which practically eliminates the yellowing which can be experienced during the treatment of certain polyamide and elastane-based fabrics, and is also equipped with a Conticlean circulating air filter system for constant high drying capacity.

Software
The latest Qualitex visualisation software offers operators reliability and easy control with its full HD multi-touch monitor and slider function, dashboard function with individual adaptation to operating states and faster access to comprehensive recipe data management.

With the Monformatic control system, the exact maintenance of the dwell time in combined treatment processes (drying and heat-setting) can be monitored. When the heat-setting point is reached, the fan speed is automatically adjusted, keeping energy consumption fully under control.
