Aus der Branche

Members of TMAS – the Swedish Textile Machinery Association – will be taking part in the forthcoming ITMA Asia + CITME exhibition, taking place from November 19-23 2023 at the National Exhibition and Convention Centre in Shanghai, China.

Weaving
In the area of weaving, 93% of the 114,000 new looms delivered in 2022 went to Asia, according to the latest figures from the International Textile Manufacturers Federation (ITMF), with China the top destination, followed by India.
As a result, TMAS members like Vandewiele Sweden AB and Eltex have a huge market to address that has been established over many decades.

Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of the market-leading Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

Yarn and sewing thread monitoring
With nearly 70 years of expertise in yarn sensor technology, Eltex of Sweden AB has been at the forefront of new product development. Its EYE and EyETM systems are capable of accurately and efficiently monitoring the movement and tension of more than 1,000 yarns simultaneously. These systems are suitable for various applications and fibre types, including warping, winding, multiaxial weaving and new material applications.

Eltex sewing tension monitors, such as the ETM422, have been well-received by customers. This device can monitor the tension of sewing threads in real time, effectively improving the quality and safety of sewn products. Particularly in China's rapidly growing automotive manufacturing sector, the ETM422 has seen widespread use to meet the industry’s escalating demands for product safety and quality.

Dyeing and finishing
“Digitalisation, automation and AI have become the key enablers for sustainable gains across the entire textile industry and so much has been achieved in the past few years, especially in terms of automation,” says TMAS secretary general Therese Premler-Andersson. “One area in which TMAS members are really making a difference right now, is in replacing water and energy-intensive technologies for the dyeing and finishing processes with new digital technologies.”

The TexCoat G4 non-contact spray technology for textile finishing and remoistening, for example, will be showcased in Shanghai by Baldwin. It not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to a customer’s requirements in terms of single and double-sided finishing applications. The TexCoat G4 can reduce water consumption by as much as 50% compared to traditional padding application processes.

A delegation from TMAS, the Swedish textile machinery association, will participate in the forthcoming Febratex textile show which is being held in the German Village Park in Blumenau, in Santa Catarina, Brazil from August 23-26.

As the fourth largest textiles manufacturer in the world, Brazil’s annual revenues from textiles and apparel amount to an annual $48 billion and the industry employs around 1.5 million people directly.

As with the USA and many European countries, product shortages resulting directly from the Covid-19 pandemic, and subsequent supply chain difficulties, have emphasised to Brazil’s industry the attractiveness of more diversified and shorter supply chains which are closer to customers wherever possible. In the past two years, there has been less reliance on imports from Asia to Brazil, and opportunities are arising again for local manufacturing.

Svegea of Sweden has supplied many automatic collarette cutters to Brazilian companies, which are used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

Svegea supplies many other bespoke machines for applications in the production of both garment components and technical textiles, including rewinding, measuring, inspection and band knife machines.

Eton Systems, the inventor and world’s leading provider of automated production systems for apparel and other textile-based processes, has supplied a large amount of workstations to Brazilian companies over the years, and believes its newly-launched Opta system is good news for this market becoming more efficient and profitable.

Automation is also high on the agenda of ACG Kinna Automatic, which specialises in automation solutions for filled products such as quilts, pillows and mattresses and also has extensive knowledge in areas such as bed linen and textile filters.

Given Brazil’s extensive forestry sector, the country is a key market for Texo AB, one of the world’s leading manufacturers of weaving machines for the production of paper machine clothing (PMC).

All paper manufacturing machines require a regular supply of PMC, which as large continuous engineered fabrics, carry the paper stock through each stage of the paper production process. With technologically sophisticated designs, they employ fibres and other polymeric materials in complex structures and each paper machine has an average of ten separate fabrics installed on it. Although the PMC business represents just a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.

• Nachhaltige Infrastrukturlösungen, Sicherheit im Straßenverkehr und Gesundheitsschutz

Auf der diesjährigen Techtextil informiert Oerlikon Polymer Processing Solutions das Fachpublikum über neue Anwendungen, spezielle Prozesse und nachhaltige Lösungen rund um die Produktion von technischen Textilien. Unter anderem stellt das Unternehmen eine neue Technologie zur Aufladung von Vliesstoffen vor, die in punkto Qualität und Wirtschaftlichkeit neue Maßstäbe setzt. Vom 21. bis 24. Juni stehen in Halle 12.0 Airbags, Sicherheitsgurte und Reifencord, aber auch Geotextilien und Filtervliesstoffe und ihre vielfältigen Anwendungen im Fokus der Gespräche.

Mehr Polyester für Airbags
Airbags sind aus dem mobilen Alltag nicht mehr wegzudenken. Hauptsächlich bestehen die verwendeten Garne aus Polyamid. Durch die immer vielfältiger werdenden Airbag-Anwendungen und auch die immer größer werdenden Systeme wird heute je nach Einsatzanforderungen und Kosten/Nutzen-Abwägung oft auch Polyester eingesetzt. Vor diesem Hintergrund leisten die Technologien von Oerlikon Barmag einen wertvollen Beitrag. Neben hoher Produktivität und geringem Energieverbrauch überzeugen sie besonders durch stabile Produktionsprozesse. Darüber hinaus erfüllen sie alle hohen Qualitätsstandards für Airbags, die - wie fast alle anderen textilen Produkte im Fahrzeugbau - ein Höchstmaß an Sicherheit für die Insassen gewährleisten müssen. Und das ohne Funktionsverlust bei jedem Klima und überall auf der Welt für die gesamte Lebensdauer des Fahrzeugs.

Bitte anschnallen!
Sicherheitsgurte spielen eine entscheidende Rolle beim Schutz der Fahrzeuginsassen. Sie müssen Zugkräfte von mehr als drei Tonnen aushalten und sich gleichzeitig im Notfall kontrolliert dehnen, um die Belastung bei einem Aufprall zu verringern. Ein Sicherheitsgurt besteht aus etwa 300 Filamentgarnen, deren einzelne hochfeste Garnfäden aus rund 100 Einzelfilamenten gesponnen sind.

Unsichtbar, aber unverzichtbar - Verstärkung von Straßen mit Geotextilien
Aber nicht nur im Auto, auch darunter entfalten technisch Garne ihre Vorteile. Niedrige Dehnung, ultrahohe Festigkeit, hohe Steifigkeit - technische Garne bieten hervorragende Eigenschaften für die anspruchsvollen Aufgaben der Geotextilien, z.B. als Geogitter im Tragschichtsystem unter dem Asphalt. Geotextilien haben üblicherweise extrem hohe Garntiter von bis zu 24.000 Denier. Anlagenkonzepte von Oerlikon Barmag stellen gleichzeitig drei Filamentgarne mit je 6.000 Denier her. Durch den hohen Spinntiter können weniger Garne kosten- und energieeffizienter auf den benötigten Geo-Garntiter zusammengefacht werden.

hycuTEC – technologischer Quantensprung bei Filtermedien
Mit der Hydrocharging Lösung hycuTEC bietet Oerlikon Neumag eine neue Technologie zur Aufladung von Vliesstoffen für eine Steigerung der Filtereffizienz auf über 99,99%. Für den Meltblownproduzenten bedeutet das eine 30%ige Materialeinsparung bei signifikant gesteigerter Filtrationsleistung. Beim Endverbraucher macht sich dies in einem Komfortgewinn durch den deutlich reduzierten Atemwiderstand bemerkbar. Mit einem bedeutend geringeren Wasser- und Energieverbrauch empfiehlt sich die Neuentwicklung darüber hinaus als zukunftsfähige, nachhaltige Technologie.

Neues Hightech Stapelfaser Technikum
Auf rund 2.100 m2 wurde bei Oerlikon Neumag in Neumünster eines der weltweit größten Stapelfaser Technika errichtet. Ab sofort stehen die state-of-the-art Stapelfaser Technologien auch für kundenindividuelle Versuche zur Verfügung.

Bei der Planung und Auslegung des Technikums stand die Optimierung von Komponenten und Prozessen im Fokus. Besonderes Augenmerk wurde dabei auf eine einfache und zuverlässige Übertragung von Prozess- und Produktionsparametern der Technikumsanlage auf Produktionsanlagen gelegt. So ist der Aufbau der Faserbandstraße modular gestaltet. Alle Komponenten können variable miteinander kombiniert werden. Umfangreiche Set-up Möglichkeiten liefern detaillierte Erkenntnisse für den jeweiligen Prozess unterschiedlicher Faserprodukte.

Das Technikum ist außerdem mit zwei Spinnpositionen für Mono- und Bikomponenten Prozesse ausgestattet. Für beide Prozesse werden die gleichen, runden Spinnpakete eingesetzt, die sich durch sehr gute Faserqualitäten und -eigenschaften auszeichnen und mittlerweile auch in allen Oerlikon Neumag Produktionsanlagen mit großem Erfolg eingesetzt werden. Zusätzlich wird die Spinnerei noch um Automatisierungslösungen, wie beispielsweise Düsenwischroboter, ergänzt.

IRO AB, a member of the Vandewiele group, reports strong interest in its ZTF Zero Twist Feeder introduced at the recent ITMA 2019 in Barcelona, Spain, particularly from companies involved in the growing market of textile reinforcements for composites.

In the weaving of fibres such as carbon, glass and aramids, as well as thermoplastic tapes for highly-engineered composite fabrics, it is essential that there is no twist in the feed, which this new machine absolutely guarantees.

“The ZTF Zero Twist Feeder keeps the tape yarns or fibre tows constantly stretched to avoid the risks of any snarls or twisting,” explains Sales and Marketing Manager Pär Hedman. “During ITMA 2019 I spoke to many companies interested in this new machine, which will be supplied in bespoke versions specific to the individual needs of each customer and the intended end-use.”

A focus on customer service, aligned with the drive to constantly innovate, has long ensured that the member companies of TMAS – the Swedish texile machinery manufacturers’ association – stay well ahead of the curve.

“All of the Swedish textile machinery companies are doing really well in major markets such as Europe, China, India and the USA,” says TMAS Secretary General Therese Premler-Andersson. “They are now gathering forces to prepare for the most important show – ITMA 2019 in Barcelona in June. I expect to see new players and partnerships as we enter the industry 4.0 era for real. We are ready to display an even higher degree of the real time monitoring of processes, automation, flexible customisation, and the incorporation of robots into production lines.  Our customers expect a lot of in terms of knowledge and our ability to customise and offer turnkey solutions.”

The forward-looking attitude of the Swedish companies is perhaps best summed up by Reimar Westerlind, the owner, since 1961, of ACG Gruppen.
At the age of 90, Reimar still travels to his office every day to oversee the operations of the diverse companies operating under the ACG umbrella.
“Everything now is about automation and digitisation,” he says. “We have to be on that track or we will be lost – innovate or die.”

Robotics
One ACG Gruppen company moving rapidly forward with new innovations in this area is ACG Kinna, which at ITMA 2019 will be providing dramatic live demonstrations of its new robotic pillow filling system.
This has the ability to fill and finish some 3,840 pillows per eight-hour shift, which is a considerable improvement on what is currently possible with existing systems, resulting in significant savings in both labour and energy for busy home textile businesses.

At ITMA 2019, Eton will be demonstrating a complete material handling solution with advanced software providing real-time information covering every aspect of the process.
“Our systems are a natural fit with the major Industry 4.0 networked manufacturing plants that are now being constructed worldwide for sectors such as the garment and home textiles manufacturing and automotive industries,” says Eton’s Sales and Commercial Director Roger Ryrlén.

Sensors
Advanced senor developments are playing a large part in moving many areas of the textile industry forward too.
Eltex of Sweden, for example, is achieving considerable success with its yarn fault detection and tension monitoring systems across a range of sectors, including the tufting of carpets, the creeling of woven materials and even the production of woven reinforcements for the composites industry.

At successive ITMA shows, IRO AB has also consistently introduced new milestones in the field of yarn feeding technology for weaving machines, and ITMA 2019 will be no exception.
“Following significant investment in our R&D capabilities, we have been making great progress in further boosting the efficiency and performance of our expanding X3 range,” says IRO AB Managing Director and Chairman of TMAS Mikael Äremann. “I can’t remember a time since the 1980s when we had so many new innovations to unveil at an ITMA, and I’m greatly looking forward to the positive response to them we are anticipating in Barcelona this June.”

Resource savings
ITMA 2019 will meanwhile see the launch of TexCoat G4 – the next generation of Baldwin Technology’s non-contact precision application system for fabric finishing. The TexCoat G4 enables a continuously high-quality and productive textile finishing process with zero chemistry waste and minimised water and energy consumption.
The non-contact spray technology brings a range of advantages including single or double-sided application,  the elimination of Foulard bath contamination, low wet pick-up levels leading to the elimination of drying steps, zero chemistry waste in changeovers of chemistry, colour or fabric, and the possibility of batch reporting, visibility of pad loading, chemical usage etc.

Other TMAS companies exhibiting in Barcelona include Texo AB, whose wide-width weaving looms make the belts for machines on which half of the world’s paper is made, ES-Automatex, which specialises in bespoke automation concepts and Svegea, a company leading the field in a number colarette machines and cutting and slitting equipment.

“At the last ITMA in 2015 in Milan, there was much talk about Industry 4.0 technologies but certainly from the perspective of TMAS, ITMA 2019 will be the place for concrete solutions as to how data and the new tools we have available can be exploited to the full,” says Therese Premler-Andersson. “There is already much more networking between the companies, with software very much the enabler and common interfaces bringing ideas closer together. We are greatly looking forward to further exchanges of ideas when meeting with customers old and new in Barcelona.”
