• Kettelhack GmbH – a German leader in the dyeing and finishing of monochrome fabrics for high-quality and durable workwear and bed linen – has this year retired its existing Monforts sanforizing line after 35 years of daily service, replacing it with a new one.

The first line was installed in 1985 during a decisive time for the company.

Taking the helm in the early 1980s, Jan Kettelhack – the current CEO, owner and great grandson of Heinrich Kettelhack who founded the company back in 1874 – made a number of decisions that have secured its success over the following decades.

In 1982 Kettelhack had to vacate its existing plant in the city of Rheine due to urban development restrictions and despite a general sense of crisis in the European textile industry at that time, opted to relocate and build a new highly automated plant that was not reliant on mechanical and personnel-intensive processes. This was aligned with a greater focus on competitive international sales.

From 1986, the company’s proficiency as a specialist in solid-colour textiles led to workwear textiles becoming a bedrock of the business. Continuous investments in machinery and technical equipment have resulted in a fully integrated and rationalised single source site dedicated solely to what the company does best – the expert dyeing and finishing of textiles.

Crucial process steps

These stages in the textile value-added chain, Jan Kettelhack has observed, are crucial to the quality of a final product in workwear – whether it stands the test in everyday use, how comfortable it is, and how many washes it can withstand.

Central to this is the sanforizing process, which pre-shrinks a fabric by compressing it prior to washing. This limits any residual or further shrinkage in a made-up finished garment to less than 1%, to ensure perfect comfort and fit over an extended lifetime.

“We certainly can’t complain about the performance of the old Monfortex sanforizing line which gave us so many uninterrupted years of service, but certain spare parts for it were becoming increasingly hard to source, the control unit was becoming a little unstable and we couldn’t risk potential interruptions to our production schedule,” says Kettelhack plant manager Hendrik Pleimann. “In many ways, the new Monfortex sanforizer is much the same as the old one in terms of its mechanical reliability and robust construction, but of course today’s drives are much more efficient, and when it comes to the automation features and control units – and the data we can generate and analyse for increasing efficiency – that’s a whole new world.”

Qualitex 800

The two-metres-wide Monfortex line benefits from the latest Qualitex 800 control system which allows all parameters to be easily automated via the 24-inch colour touchscreen, including production speed, control of all fabric feed devices, rotation spray or steaming cylinder options, the width of the stretching field and the rubber belt pressure.

The integrated Compactomat system allows a continuous indication and control of the shrinkage values and the temperatures of the shrinking cylinder and felt calender. Up to 10,000 separate process parameter records can be generated and stored by the data manager.

Full line management can be optimised via the batch-specific calculation of all process material consumption and water and electricity use, with any standstill times analysed and immediately corrected for the future.

Any further assistance required is available via Monforts Teleservice, with direct connection to technicians and virtual access to machine analysis.

Professional

Commissioning of the new Monfortex line at Kettelhack commenced in January and it was fully operational in a relatively short time.

“This was a very professional installation provided by the Monforts team with whom we have a very good relationship dating back many years, and everyone knew what was required from both sides,” says Mr Pleimann. “Our operators have found the new line very user friendly and we are very pleased with how everything proceeded so smoothly. An unexpected benefit is that the new line is also a lot quieter, of course, which is something our operatives are appreciating.”

Key features of the Monfortex line are the proven fabric preparation, weft straightening and spreading units, prior to the compressive shrinkage machine with a 750mm shrinking cylinder, and a felt calender equipped with 2,000mm diameter drying cylinder. The line also features an integrated automatic grinding unit.

Customer service

Kettelhack is processing primarily cotton and polyester woven fabrics, with lyocell becoming increasingly popular in workwear for its softness and comfort.

As part of its customer service, the company stocks more than a million metres of grey fabric and at least 1.2 million metres of finished and rolled standard fabric in its warehouse at any one time, with a further 750,000 metres permanently in production.

While a significant cost, this commitment ensures Kettelhack customers can be fully flexible and rely on it as a partner.

“As a family-run company with around a hundred employees, Kettelhack operates very differently to bigger businesses which have to constantly consider their immediate quarterly profits,” Mr Pleimann concludes. “The thinking at Kettelhack is in terms of the next twenty years and ensuring that the business will be just as successful for the next generation as it is today. We also have a very flat organisational structure in which everyone is involved and takes an active part, which makes it a very nice place to work.”

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, 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.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

• Anforderungs- und passformgerechte textile 3D-gestrickte Mund-Nasen-Masken – Weitere Initiativen am ITM der TU Dresden

Seit dem 20. April 2020 gilt für das Bundesland Sachsen eine Maskenpflicht beim Einkaufen und im öffentlichen Personen- und Nahverkehr. Eine entsprechende Verordnung wurde hierfür am 17. April 2020 vom Freistaat Sachsen bekannt gegeben.

Aufgrund der neuerlassenen Allgemeinverfügung und der damit einhergehenden, notwendi-gen Schutzmaßnahmen zur Verringerung der Ausbreitung von COVID-19 wird das Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik (ITM) der TU Dresden nach der am 20. April 2020 erfolgten Wiederaufnahme des laborbasierten Forschungsbetriebes die bereits in der ITM-Pressemitteilung vom 31. März 2020 vorgestellte textile, 3D-gestrickte Mund-Nasen-Maske intensiv weiterentwickeln. Das ITM möchte damit einen wichtigen aktiven Beitrag zum Schutz der Gesundheit der Bevölkerung leisten.

Hierfür sind in den letzten Tagen die Kooperationen mit langjährigen Netzwerkpartnern des ITM wei-ter intensiviert worden. Gemeinsam mit der renommierten Textilmaschinenfirma H. Stoll AG & Co. KG aus Reutlingen ist es gelungen, mit dem am ITM erarbeiteten technologischen Know-how auf einer am ITM der TU Dresden installierten Flachstrickmaschine Stoll ADF 530-32 BW weitere Vari-anten neuartiger, textiler 3D-gestrickter Mund-Nasen-Masken erfolgreich umzusetzen.

Am ITM können somit Mund-Nasen-Masken-Varianten mit unterschiedlichsten Materialkombinatio-nen auf Flachstrickmaschinen von zwei Maschinenherstellern, die sich alle als waschbarer und damit wiederverwendbarer Mund-Nasen-Schutz eignen, anforderungs- und passformgerecht gefertigt wer-den. Je nach Materialzusammensetzung sind die Mehrwegmasken für Kochwäsche mit handelsübli-chen Waschmitteln bzw. bei 60° mit Desinfektionswaschmittel geeignet. Bei den Masken kann wahl-weise eine Tasche direkt im Fertigungsprozess integriert werden, in die temporär noch zusätzlich Fil-terstrukturen eingelegt werden können. Die gestrickten Mund-Nasen-Masken sind – intuitiv, schnell, unkompliziert in der Handhabung – auch für Brillenträger geeignet und erfordern beim Anlegen keine Hilfe einer weiteren Person. Mittels weiterer anforderungsgerechter Materialkombinationen können auch spezifische Eigenschaften, wie z. B. Atmungsaktivität, Tragekomfort und Hautverträglichkeit, ge-zielt eingestellt und diesbezüglich im Rahmen erster freiwilliger Versuchsreihen mit Mitarbeitern des ITM intensiv getestet werden.

Als eines der weltweit führenden Textilforschungsinstitute wird das ITM mit der lösungssystemati-schen Entwicklung anforderungsgerechter Mund-Nasen-Masken einen wichtigen gesellschaftlichen und nachhaltigen Beitrag für das Gemeinwohl der Bevölkerung leisten. Das Team des ITM, welches maßgeblich bei der Maskenentwicklung involviert ist, freut sich daher auf weitere Anfragen von Her-stellern und Produzenten, um mit dem erarbeiteten Fachwissen bzw. Erfahrungen und technologi-schem Know-how insbesondere die KMU der deutschen Textilindustrie beratend zu unterstützen und ggf. gemeinsame Allianzen/Kooperationen zu schmieden.

Bereits jetzt schon steht das ITM mit mehreren Industriepartnern in Kontakt, um die Technologie zur Fertigung von textilen 3D-gestrickten Masken schnell in die Serienproduktion zu überführen und dar-über hinaus diese anforderungsgerechten textilen Produkte auch zeitnah als nach den geltenden Standards bzw. Richtlinien zugelassene Schutzmasken anzubieten.

Für die zielführenden Untersuchungen mit variablen Materialkombinationen zur weiteren Op-timierung der unterschiedlichen Maskenvarianten wurden dem ITM bereits verschiedenste Versuchsmaterialien kostenfrei zur Verfügung gestellt. Das ITM bedankt sich hierfür bei folgenden Firmen: EMS-CHEMIE AG, Gebrüder Otto GmbH & Co. KG, TWD Fibres GmbH und W. Zimmermann GmbH & Co. KG.
 

The origins of both Industry 4.0 and an awareness of the need for more sustainable manufacturing methods can arguably be traced back to the year 1971.

It was in 1971 that the first microprocessor was introduced by Intel, and also that the first and perhaps now most well-known environmental campaigner, Greenpeace, was founded.

As such, a direct line can be charted from that year to today’s automated textile manufacturing machinery concepts, as well as the drive to develop more increasingly resource-efficient processes.

All of the recent innovations which have been introduced to the market by A. Monforts Textilmaschinen GmbH & Co. KG, for example, are being powered by the possibilities of Industry 4.0 and developed in response to the market demand for more sustainable production.

They include the new ‘digital twinning’ capability introduced in 2019 for all Monforts machines, with advanced sensor technologies which make it possible to access comprehensive technical machine data from any location using the company’s Smart Support and Smart Check apps. In addition, the digital twin system provides information on individual wear parts, such as, for example, converters or gears.

These latest developments have been very favourably received by Monforts customers, especially in Europe.

50th anniversary
The very first Heimtextil – the leading trade fair for the home textiles market – was also held in Frankfurt in January 1971 and Monforts customers Bierbaum Group and Konrad Hornschuch AG are amongst the German companies who were there from the very start and have attended every annual show since.

Bierbaum Group, based in Borken, is the company behind the well-known Irisette bedding brand and is celebrating its own 125th anniversary in 2020. It has also introduced products bearing the German government’s new Grüner Knopf textile seal of approval for sustainable production.

As a specialist in synthetic leathers for home surfaces, as well as vehicle interiors, Konrad Hornschuch AG, of Weissbach, has been a member of the €44 billion automotive giant Continental AG since 2016.

Representatives from both companies received memorial trophies at a special presentation held on January 7th during the 50th anniversary Heimtextil show.

The home textiles market remains very strong in Germany, with sales amounting to some €9.6 billion in 2019, according to analyst IFH Cologne.

Global growth
The first Heimtextil in 1971 was a significant success, attracting 679 exhibitors from 26 countries.

This year’s show, however, attracted a total of 2,952 exhibitors from 66 countries, reflecting not only the growth of the home textiles industry, but also the globalisation which has taken place over the last half century.

Monforts now has customers for its advanced finishing technologies around the world, with home textile customers from India and Pakistan being particularly well represented at Heimtextil 2020.

Among stand outs from Indian companies at this year’s show was the 2020 collection of Welspun India’s famous Christy England brand, inspired by botanical studies of the gardens of British stately homes. Welspun towels meanwhile benefit from the company’s HygroCotton hollow core yarn technology, produced by a proprietary spinning method which ensures they become softer, fluffier and more absorbent after every wash.

An equally ground-breaking new technology is being introduced by Trident Group, which is one of India’s largest vertically-integrated home textiles manufacturers and two years ago installed five complete Monforts finishing ranges for its new linen department.

Trident’s patented Air Rich yarns feature pores throughout their cross sections for high breathability and absorbency, as well as rapid drying.

Monforts home textile customers from Pakistan stressed the resource efficiency of their processes and products as a result of investments in advanced technology, and during the show the ‘Sustainable Pakistan’ initiative was announced.

Supported by GIZ, the German Society for International Cooperation, the initiative aims to reshape global perceptions of Pakistan’s manufacturers and their innovations. So far, twenty producers have been carefully chosen to be presented on this global platform and will help rebrand Pakistan’s textile industry at the Heimtextil exhibitions going forward.

Heimtextil’s organiser Messe Frankfurt also announced its own new alliance with the United Nations Office for Partnerships, in order to support the UN’s Sustainable Development Goals.

Constancy
Many things have changed since 1971 and home interiors are certainly no longer predominantly orange and brown – and perhaps unlikely to ever become so again.

It’s clear, however, that there has been a constancy in the push to consistently improve textile technologies, processes and products that may have originated in Europe, but have subsequently spread around the world.

And the significance of both microprocessors and sustainability in 2020 could only have been guessed at back in 1971.

Monforts Textilmaschinen GmbH & Co. KG will be providing information on its extensive range of coating and finishing technologies for the production of nonwovens and technical textiles at the forthcoming Techtextil India exhibition.

“India is already a very important market for Monforts and there are exciting prospects ahead for Indian manufacturers of technical textiles, who are well positioned to capitalise on growth opportunities,” says Monforts Head of Denim Hans Wroblowski, who will be at the Monforts stand in Hall 4, booth C52 at the show. “India has one of the largest working-age populations in the world and a complete textile value chain for both natural and synthetic fibres.”

In addition, he adds, India’s government, through its Ministry of Textiles, has been actively promoting the growth of technical textiles through various programmes based on investment promotion, subsidies, the creation of infrastructure and the stimulation of consumption.

As a result, India’s Ministry of Textiles is forecasting that the growth of technical textiles in the country will be over 18% annually in the next few years, from a value of US$16.6 billion in 2018 to US$28.7 billion in 2021.

Value addition

High value-added technical products such as wide-width digital printing substrates, carbon fabrics for high-performance composites, filter media, flame retardant barrier fabrics and heavy-duty membranes are now being coated on Monforts texCoat ranges and finished with the company’s industry-leading Montex stenters.

“Since we acquired the technology that our coating units are based on in 2015, we have made a lot of refinements,” says Hans. “All of these developments are reflected in higher coating accuracy and the resulting quality of the treated fabrics. At the same time, our latest multi-functional coating heads offer an unprecedented range of options, with a wide range of modules available.”

The texCoat user interface is now equipped with the unique Monforts visualisation system and the magnetic doctor blade has greater power reserves. Options include a carbon fibre-reinforced composite coating drum with a more scratch-resistant surface and maximum rigidity and remote control which simplifies exact adjustment for the operator.

Montex stenters in special executions are meanwhile ideal for the drying and finishing of both technical woven fabrics and nonwovens and characterised by high stretching devices in both length and width.

“The European-built Montex range of stenters has earned its leading position in the technical textiles market due to the overall robustness, reliability and economy of these machines,” Hans concludes. “Whatever the intended end-product – and we continue to discover potentially new areas in which technical textiles can be utilised all the time – we have the machine specification and know-how to turn ideas into reality. In India we also benefit from the strong sales and service support of A.T.E. Enterprises.”

Texchtextil India takes place alongside World of Composites at the Bombay Exhibition Centre in Mumbai from November 20-22.

It’s well-known that the astonishing success of China’s economy over the past decade has sent wages soaring and made it difficult for the country’s textile manufacturers to find and retain trained machine operators, while operating in a highly competitive market where optimised production and full resource efficiency are of paramount importance.

In direct response to this situation, A. Monforts Textilmaschinen GmbH & Co. KG has introduced a range of new Industry 4.0 technologies aimed at simplifying machine operation while providing easy access to all data and instant or remote assistance.

At the forthcoming Shanghaitex 2019 textile machinery exhibition, which takes place from November 25-28 in Shanghai, Monforts specialists will be at stand A10 in Hall W and look forward to discussing the company’s latest developments in this area with valued Chinese customers.

They include the latest Qualitex full touch panel control system, with its digital twinning capability and Smart Check and Smart Support apps, reinforced by the comprehensive Monforts Smart Sensor machine monitoring programme.

The new Monforts yarn dyeing technology is being made commercially available at exactly the right time for fabric differentiation and cost efficiencies, if the initial market reaction at ITMA 2019 is anything to go by.

A revolutionary new system for yarn dyeing based on the proven Econtrol® dyeing system for fabrics will be introduced by A. Monforts Textilmaschinen GmbH & Co. KG at ITMA 2019 in Barcelona, Spain, from June 20-26.

This latest CYD denim processing technology integrates new functions and processes into the weaving preparatory processes – spinning, direct beaming, warping and assembly beaming, followed by sizing and dyeing – in order to increase quality, flexibility, economic viability and productivity.

“Denim finishing is a field in which Monforts has an undisputed lead and we have been working closely with our many partners in the key denim manufacturing countries of China, Bangladesh, India, Pakistan, Mexico and Brazil to develop new advanced solutions,” says Monforts Head of Denim Hans Gerhard Wroblowski. “The CYD system has been developed in response to a very strong market demand.”

A. Monforts Textilmaschinen GmbH & Co. KG will demonstrate a range of new advances made possible by Industry 4.0 techniques at ITMA 2019 in Barcelona, Spain, from June 20-26.

At stand D101 in Hall 2, visitors will discover the possibilities of ‘digital twin’ capability – now being made available for all Monforts machine systems – and that by exploiting the latest advanced sensor technology, comprehensive technical machine data can now be virtually mapped in the cloud in real time. The data can be easily accessed using the new Monforts Smart Support and Smart Check apps for an instantaneous status overview. All specifications relating to machine performance and the production process can be mapped, to enable vastly simplified and targeted analysis for controlled planning and production. Insights harnessed from such analysis can be used to optimise the actual production process. At the same time, potential sources of error can be anticipated and eliminated, enabling improved machine availability while considerably minimising downtime.

Parts prediction
In addition, the digital twin system provides information on the individual wear parts of a system, such as, for example, converters or gears. “Operators and mill managers are informed by Smart Check sensors when maintenance or the replacement of key components will be required, well ahead of time,” explains Monforts Vice President Klaus A. Heinrichs. “Direct access to the integrated Monforts webshop allows users to instantly order such parts when they are needed, virtually preventing machine downtime.” On request, Monforts can also virtually monitor machine performance and pro-actively alert customers to the need for preventative action. In such cases, however, data is only ever called from the cloud by Monforts when customers have given their full consent, in the interests of data security. Data from Smart Check, for example, can even be used to analyse a system’s energy requirements, allowing machine operation to be optimised by tailoring production runs to the peaks and troughs of electricity costs.
