From the Sector

In den Laboren der textilen Studiengänge an der Hochschule Albstadt-Sigmaringen stehen pünktlich zum Start ins Sommersemester zwei brandneue Maschinen, die den Studierenden ebenso zur Verfügung stehen wie Interessierten aus der Textilindustrie.

„Wir testen gerade den Prototypen einer Flüssigklebemaschine“, sagt Prof. Matthias Kimmerle. Dabei handelt es sich um eine Weltneuheit, die es bislang noch nirgendwo sonst gibt – möglich wurde diese Leihgabe durch die hervorragenden Kontakte der Hochschule zum japanischen Hersteller. Das Neue daran: Anstatt Kleidung zu nähen, werden die einzelnen Schnittteile geklebt. „Die Ergebnisse sind sehr überzeugend“, sagt Matthias Kimmerle. „Die Kantenführung erledigt die Maschine vollautomatisch und hält dabei die Abstände exakt und konstant ein.“

Ein Wäschehersteller aus Albstadt hat die Maschine bereits erfolgreich ausprobiert, „und wir selber testen sie mit Funktionsmaterialien, wie sie bei Unterwäsche oder Sportkleidung benutzt werden“. Hier seien störende Nähte häufig unerwünscht, und die Klebetechnik kann genau dieses Problem lösen. Die Maschine steht noch ein paar Wochen in Albstadt zur Verfügung, bevor sie zu einem Textilunternehmen nach Österreich umzieht.

In der Lernfabrik der textilen Studiengänge steht außerdem seit vergangener Woche der Prototyp eines neuen Etikettierers (angedockt an einen Zünd-Cutter), der die Schnittteile nach dem Ausschneiden automatisch etikettieren kann. Eine solche Maschine sei für viele Branchen nützlich, „insbesondere dann, wenn in der Produktion viele Teile hergestellt werden, die sich ähneln“, sagt Matthias Kimmerle. Ermöglicht wurde die Anschaffung durch Marc Witzemann, Geschäftsführer von Rebstock Consulting, der die Maschinen des Herstellers in Deutschland vertreibt und die Hochschule seit Jahren mit der Dauerleihgabe von Cuttern unterstützt. „Es ist uns ein großes Anliegen, dass Studierende und kleinere Unternehmen die Möglichkeit bekommen, auf neuer Technik etwas zu testen“, sagt er. Wie wichtig genau das im sehr praxisbezogenen Studium an der Hochschule ist, betont auch Matthias Kimmerle. „Die Maschine passt zudem perfekt zu unserer Microfactory.“ Diese ermöglicht es, selbst kleine Losgrößen von nur einem Stück auf Kundenwünsche angepasst herzustellen.

Monforts will highlight its advanced finishing and coating technologies for the production of technical textiles at Techtextil North America, which takes place at the Georgia World Congress Center in Atlanta from May 17-19.

The company and its US representative PSP Marketing, of Charlotte, North Carolina, will be part of the centrepiece VDMA German Pavilion at the show.

Energy prices
With energy prices continuing to go through the roof, an emphasis at Techtextil North America will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air. This results in a radical reduction in the conventional heat supply required. A range of further resource-saving and energy recovery options can be specified per individual line installation.

Advanced machine operation
With the highly intuitive Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Versatility is the key
Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

Turkish powerhouse in home textiles and furnishing fabrics Altun Tekstil has just commissioned the first Montex®Coat coating system in Turkey.

The advanced machine has been installed at the ever-expanding family-owned company’s industrial complex in Bursa and is being employed to provide an anti-slip and textured backing to upholstery fabrics with a stable and uniform foam, via knife-over-roller coating.  

Founded in 1993, Altun exports its fabrics to more than 60 countries, with its major export markets being Russia and Ukraine, as well as many Middle Eastern and European countries.
Its integrated operations include the production of texturized yarns, weaving and raschel knitting, in addition to dyeing and finishing. With a major focus on tulle curtains and upholstery, the company’s fabric range also extends to a wide variety of apparel styles.

Altun has installed eight stenters in various widths at its two plants since 2016 – coincidentally the year Monforts Turkish representative Neotek was founded. All of the stenters are engineered for specific product lines and the Montex®Coat unit is integrated into the latest of these lines, which has a maximum working width of 2.2 metres and eight chambers.

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.

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.

Wülfing GmbH is one of the oldest but also one of the most modern home textiles companies in Germany, with its main weaving and finishing operations located in Borken, North Rhine-Westphalia, and a further jacquard weaving mill in Steinfurt, as well as with a making up and packaging plant in the Czech Republic.

At its Borken plant, Wülfing has employed a Monforts sanforizing line since 2009 to guarantee the required dimensional stability and shrink-fastness of its high quality bed linen. With a working width of over three metres, the sanforizing process is a central pillar in the production of typical wide-width cotton fabrics for home textiles.

In 2017, the company was able to acquire a second Monforts sanforizing line from another company which, although built in 2005, had been virtually unused. It was overhauled and installed behind a Monforts equalizing frame of a similar age.

“Unfortunately, the two machines had to be operated separately via individual controls and did not represent an integrated unit,” says Schulte-Mesum. “This resulted in deficits in the desired productivity and in the control technology.”

Wülfing consulted with Monforts on a number of upgrade options and opted for a completely new joint control system to merge the two machines, as well as a new connecting inlet, a tensioning and damping field and a steaming unit.

“Monforts provided a fast and precise erection and commissioning of the technology in spite of the difficult pandemic circumstances,” says Schulte-Mesum. “The result has been an increase in production speeds by 20% and enhanced uniformity in fabric width through a much improved guidance system.

“We are also achieving energy savings as a result of the new control and drive technology and operation has been simplified and improved as a result of the unified control. We benefit from simplified access for maintenance work such as the grinding of the rubber blanket, but most of all we have greatly improved our flexibility and now have two almost identical Monforts sanforizing lines.”

Klaus Heinrichs began working in marketing for the company in 1992. “From the very beginning until today Klaus used his great flair and networking skills to secure and improve the company’s international presence and public relations, especially at seven successive ITMA textile machinery exhibitions, beginning with the show in Milan in 1995,” said Monforts Marketing Manager Nicole Croonenbroek.  “Later, he also took care of customer service, sales administration and exports in his uniquely calm and quietly-spoken style.”

“He has always been a guarantor of successful product launches for Monforts technical and technological highlights such as the TwinAir principle of independent airflow regulation, the Hercules LTM stenter chain, the Econtrol® dyeing technology or the Montex®Coat device - to mention only a few.”

Klaus has also been active on the VDMA’s Exhibition and Marketing Committee since 1993, which he chaired from 2005 to 2008.  
“Klaus always enriched the industry discussions with practical and future-oriented proposals and thus also advanced ITMA,” said Thomas Waldmann, Managing Director of the VDMA Textile Machinery Association. “We sincerely thank him and wish him all the best for this new chapter of his life.”

“We will miss Klaus as a colleague and as a manager because of his skills, character and his engagement,” added Monforts Managing Director Stefan Flöth. “He truly represents the Monforts commitment to our customers to be helpful, accurate, fast and reliable, and we keep him as a friend. I’m sure the many friends he made throughout the world during his career with the company will join us in wishing him all the best for his next phase of life together with his family.”
