Aus der Branche

Monforts Head of Technical Textiles Jürgen Hanel will take part in the next international webtalk to be held by the VDMA’s textile machinery division on May 20th.

He will be joined by Johannes Lutz, Research and Development Engineer at Pleva, to provide full details of how the latest Monforts coating technology is supported by special microwave measuring systems.

The Montex®Coat magnetic roller coating option allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process.

“This roller provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater,” Hanel said.

Lutz will provide an overview of the use of Pleva microwave measurement technology in coating processes, in addition to the latest developments in electronic evaluation.

To ensure a constant high quality in coating operations it is necessary to accurately measure and control the amount of chemical being applied, and Pleva’s series 700 devices achieve this via contact-free microwave moisture measurement technology which can be supplied either as single- or three-point units, or as a traversing measurement unit.

The free-to-attend webtalk will take place on May 20th from 2-3pm (CEST) and registration can be made here, along with further information.

Flexibility, product uniformity and automation are the keys to success for coating businesses in today’s rapidly-changing technical textiles industry, explained Jürgen Hanel, Monforts Head of Technical Textiles, at the recent 1st World Congress on Textile Coating.

Introducing the latest Montex®Coat magnetic roller coating option to virtual delegates from around the world at the conference organised by International Newsletters, Hanel explained why this technology makes perfect sense now

“The magnetic roller system allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process,” he said. “It provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater.”

With traditional dip coating systems, he added, as well as with many standard knife coating technologies, there is always a difference in the tension between the centre and the edges of the wide width fabrics being treated – and hence the amount of pressure with which the coating is applied. With the use of a magnetic roller, equal pressure is applied across the full width of the fabric, with consistent results even at wide widths of over 2.4 metres. In addition, adjusting the roller surface, rather than changing the coating formulation to match the required add-on and viscosity for each coating effect required, leads to much higher output from the line.

Cleaner and less wasteful
The contribution of such flexible and resource-saving new technologies to a cleaner and less wasteful textile industry was a key theme at the congress – held virtually across the four afternoons of February 11th, 12th, 18th and 19th – as was digitalization and the many advantages it is providing.

“A typical integrated Monforts coating line is automated from the inlet feed to the winder,” Hanel told delegates. “Adjustments can also be made simply and easily from the touchscreen and with the new hand-held remote controller which has recently been introduced for the Montex®Coat unit.”

Manual adjustment, he added, is time consuming and needs the attention of an experienced operator or the reproducibility will not be accurate between coating operations. The adjustment by motors allows each coating to be stored and downloaded again for 100% reproducibility.

The motors can be fully controlled from the touchscreen and all necessary adjustments carried out remotely, making switching from one process to another extremely quick and easy.
The accuracy that is now being demanded by today’s most exacting customers is met with an optional carbon fibre roller – especially in dealing with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics. Typical applications for the Montex®Coat include the finishing of tents 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 can all be accommodated.

“The World Congress on Textile Coating was characterised by some very stimulating presentations and forums between the speakers and a global audience of textile specialists,” Jürgen Hanel concluded. “It truly reflected the high level of positive changes now taking place in not just textile coating, but the entire textile industry. I look forward to the next edition, which hopefully will be a face-to-face event for even deeper level discussions and debate.”

• Monforts customer Kipaş has been selected as the sole denim manufacturing partner in the €6.7 million European Union-funded New Cotton Project, involving the brands adidas and H&M, working in a consortium with suppliers, innovators and research institutes.

Kipaş, based in Kahramanmaraş, Turkey, is currently installing its third Monforts Montex stenter along with a third Monfortex compressive shrinkage system in a combined configuration dedicated to denim production.

This follows the successful installation and commissioning of the second Montex and Monfortex lines at the Kahramanmaraş plant in 2018, which Kipaş Vice Chairman of the Board Ahmet Öksüz said had immediately exceeded expectations.

“We performed a very thorough technical investigation based on the latest Industry 4.0 analysis before the purchase, to determine what we needed, and the Monforts technology met all our requirements,” he said, in an interview with Textilegence magazine. “The Monfortex is equipped with a variety of features not found on classical shrinkage machines and the production can be monitored from beginning to end. It also exceeded our expectations in energy cost savings.”

Kipaş subsequently received a special certificate from Monforts in recognition of its exceptional utilisation of the technology to its full potential.

The latest Montex stenter now being installed at Kipaş is a 12-chamber unit with a working width of 2 metres featuring all of the latest automation features. The Monfortex unit, also with a working width of 2 metres, is in a ‘double rubber’ configuration, comprising two compressive shrinkage units and two felt calenders in line. This allows the heat setting of elastane fibres and the residual shrinkage of the denim to be carried out simultaneously, for a significant increase in production speeds.

“Around 90-95% of denim fabric production now contains elastane fibres and the Monforts system has allowed us to simultaneously increase our production and quality in this respect,” Mr Öksüz said.

Regenerated cotton
For the next three years within the New Cotton Project, Kipaş will manufacture denim fabrics based on the cellulose-based fibres of Infinited Fiber Company of Finland, made from post-consumer textile waste that has been collected, sorted and regenerated.

The patented technology of Infinited, which is leading the consortium of 12 companies, turns cellulose-rich textile waste into fibres that look and feel like cotton.

“We are very excited and proud to lead this project which is breaking new ground when it comes to making circularity in the textile industry a reality,” said Infinited co-founder and CEO Petri Alava. “The enthusiasm and commitment with which the entire consortium has come together to work towards a cleaner, more sustainable future for fashion is truly inspiring.”

Take-back programmes
Adidas and H&M will establish take-back programmes to collect the clothing that is produced, to determine the next phase in their lifecycle. Clothing that can no longer be worn will be returned to Infinited, for regeneration into new fibres, further contributing to a circular economy in which textiles never go to waste, but instead are reused, recycled or turned into new garments.

The aim is to prove that circular, sustainable fashion can be achieved today, and to act as an inspiration and stepping stone to further, even bigger circular initiatives by the industry going forward.

The EU has identified the high potential for circularity within the textile industry, while simultaneously highlighting the urgent need for the development of technologies to produce and design sustainable and circular bio-based materials. Making sustainable products commonplace, reducing waste and leading global efforts on circularity are outlined in the European Commission’s Circular Economy Action Plan.

Fashion brands produce nearly twice as many clothes today as they did 20 years ago and demand is expected to continue growing. At the same time, the equivalent of one garbage truck of textiles is landfilled or burned every second. Most of the textile industry’s environmental problems relate to the raw materials used by the industry – cotton, fossil-based fibres such as polyester, and viscose as the most common man-made cellulosic fibre, are all associated with serious environmental concerns.

During the Innovate Textile & Apparel (ITA) virtual textile machinery show which will run from October 15th-30th 2020, Monforts will be emphasising its leadership position in three key fields – advanced coating, denim finishing and fabric sanforizing.

With its multi-head capability, the latest Monforts texCoat coating system provides flexibility with an unprecedented range of options and a wide range of modules available.

Refinements
“Since we acquired the coating technology that our systems are based on we have made a lot of refinements and all of them are reflected in higher coating accuracy and the resulting quality of the treated fabrics,” says Monforts Head of Technical Textiles, Jürgen Hanel.
“Our systems have the shortest fabric path from the coating unit into the stenter and we have all variations of coating application systems too – and all of these options are available in wider widths, with the engineering and manufacturing from a single source here in Europe.”

CYD
Denim finishing is meanwhile a field in which Monforts has an undisputed lead and it has been working closely with its many partners in the key denim manufacturing countries of Bangladesh, Brazil, China, India, Mexico Pakistan and Turkey to develop advanced solutions. The latest of these is the CYD yarn dyeing system.
“CYD is based on the proven Econtrol® dyeing system for fabrics*,” explains Monforts Head of Denim Hans Wroblowski. “It 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. The CYD system has been developed in response to a very strong market demand.”

Pre-shrinking
Monforts has also recently delivered a significant number of its latest Monfortex sanforizing lines to customers around the world.
Sanforizing is vital to final fabric quality, pre-shrinking it by compressing prior to washing, to limit any residual or further shrinkage in a made-up finished garment to less than 1%, for perfect comfort and fit over an extended lifetime.

As with industry-leading Montex stenters, Monfortex lines benefit 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. Up to 10,000 separate process parameter records can be generated and stored by the data manager.

*Econtrol® is a registered mark of DyStar Colours Distribution GmbH, Germany.

• 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.”

• There is an urban legend that hemp canvas was used to make the very first pair of Levi’s jeans.
• While this is a myth that originated in the counterculture of the 1960s, hemp is without doubt the fibre of the moment for the denim industry.

At the second Kingpins24 virtual denim show that was broadcast from New York on June 23rd and 24th, the sustainable benefits of hemp fibre were referenced by many Monforts customers who are now including it in their collections, including AGI Denim, Artistic Milliners, Black Peony, Calik, Cone Denim, Naveena Denim Mills (NDM) and Orta.

“Hemp is an easy to grow fibre which requires no irrigation, no fertilizers, no herbicides and no chemicals,” says Allan Little, Director of Product Development for Cone Denim, which has recently launched its Sweet Leaf collection featuring the fibre. “Significantly, it also uses fifty per cent or even less water than cotton in cultivation.”

It can also bring some new aesthetics to denim too, he adds.

“Hemp has a unique colour and adds a different cast to our indigo, the drape and texture of the fabrics is different and it even adds  a bit of a unique hand, so combined with its sustainable credentials we are proud to be bringing the Sweet Leaf collection to the market.”

US supply chain

Cone is currently sourcing its hemp from France, but with much of its manufacturing now in Mexico – and with the introduction of the US Farm Bill in 2018 which has legalised the growing of legal hemp – is exploring the possibility of investing in the US supply chain.

“With US hemp we’re really at the R&D phase,” Little emphasises. “It’s a unique crop, so coming up with the right stalk to provide the right fibre is challenging. We’ve experimented with different types of seed and various methods of decortication.”

Decortication, he explains, is the mechanical removal of the outside layer of the hemp stalk to useable fibre on the inside. A second process, cottonization, is necessary to make the fibre suitable for spinning, because compared to cotton, hemp is longer, stiffer, and less flexible.

100% success

At the end of 2019, Naveena (NDM), headquartered in Karachi, introduced fabrics featuring up to 51% hemp content in blends with Tencel and recycled polyester and this year has developed the first 100% hemp denims.

“The response to the fabrics we showed last year was incredible and we were looking forward to the response to this latest development – which everyone was asking for – at the Kingpins show in Amsterdam, which unfortunately was unable to go ahead,” says NDM’s Director of Marketing Rashid Iqbal. “We produced initial samples in an undyed state because we were not sure how the wet spun yarn would react in the dyeing, but I’m happy to say we have had success in this respect and are now able to provide one hundred per cent indigo dyed hemp denim.”

Environmental benefits

“Differentiation is the key in the highly-competitive denim industry and we have assisted our customers with trials and optimised processing parameters for a range of different fibres, including hemp, both at our Advanced Technology Centre in Germany and at their own mills around the world,” says Hans Wroblowski, Monforts Head of Denim. “Given the environmental benefits of hemp, and the liberalisation of its cultivation in many parts of the world, the interest in it now comes as no surprise. We have the technologies and know-how to help our customers to fully maximise their hemp denims at all post-weaving stages of production.”

Monforts has a dominant position in the field of denim finishing with its well proven Montex stenters. It has been enjoying further recent success with its Eco Line concept based on two key technology advances – the Eco Applicator and the Thermo Stretch.

The latest Monforts innovation for denim is the CYD yarn dyeing system. This technology is based on the effective and established dyeing process for denim fabrics that is now being applied for yarn dyeing.

The CYD system also integrates new functions and processes into the weaving preparation processes – spinning, direct beaming, warping and assembly beaming, followed by sizing and dyeing – to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre.

Monforts has recently been involved in a number of R&D trials aimed at improving the performance of the fishing cage nets employed in fish farming operations at its Advanced Technology Centre (ATC) in Mönchengladbach, Germany.

The cultivation of both freshwater and saltwater fish populations under controlled conditions is a global industry valued at around $200 billion annually and only made possible with the use of huge aquaculture nets.

Biofouling
“These nets are very prone to biofouling and to avoid its negative impacts, high-pressure robotic jets are now used to clean them,” explains Monforts Head of Technical Textiles Jürgen Hanel. “Net cleaning is expensive and can also damage current antifouling coatings on the nets, causing contamination as well as fish health and welfare risks.
The development of more effective antifouling coatings for fishing cage nets has been one aspect of R&D work at the Monforts ATC, while the use of how alternative fibres could potentially be coated or finished to replace the polyamide which is currently most widely used has also been explored.
The issue of plastics and synthetic fibres in the oceans has generated global media attention recently, and the aquaculture industry is exploring all avenues that will lead to more sustainable practices.

Expansions
Since its opening in 2013, over €3 million has been invested in equipment at the Monforts ATC, which over an area of 1,200 square metres houses two full finishing lines, engineered to accommodate an extremely diverse range of processes, in addition to a Thermex range for the continuous dyeing of denim.

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 will be part of the VDMA Textile Machinery Association’s forthcoming delegation to Pakistan which will take place from November 11th to 14th.

In total, 14 companies covering the entire textile chain are participating in the visit, which will showcase the benefits and technological innovations of German textile machinery at seminars held in both Karachi and Lahore.

A technical seminar in Karachi will be held at the Hotel Karachi Avari Towers on November 12th and a second in Lahore will be held on November 14th at the Hotel Avari Lahore Towers.

“The regions surrounding both of these cities have become major hubs for textile manufacturing, especially in areas such as home textiles and denim, where Monforts enjoys market-leading positions with its finishing systems,” says area sales manager Manfred Havenlith, who in addition to presenting at the seminars, will be holding meetings and networking with existing Monforts customers and potential new ones during the trip. “The Punjab region around Karachi, as Pakistan’s largest city, for example, is now dense with denim manufacturers, many of whom have already expressed keen interest in the new Monforts CYD continuous yarn dyeing system we introduced at ITMA 2019 in Barcelona in June.”

In addition to launching its new and expanded website, A. Monforts Textilmaschinen GmbH & Co. KG has issued two new publications celebrating the achievements of its major customers.

The first edition of Monforts World of European Textiles profiles a range of companies at the forefront of manufacturing in Europe serving a wide range of end-use markets – from high-end silk and polyamide fabrics for the luxury brands to nonwovens and technical textiles for digital printing, protective clothing, wallcoverings and more.

The seventh edition of Monforts World of Denim meanwhile charts the latest developments from the global market leaders in denim production. Monforts enjoys a global lead in the supply of finishing technology for the denim industry and is currently extremely busy responding to the interest shown at ITMA 2019 in its new CYD yarn dyeing system for this market.

Both publications are now available to download from the new website at: https://www.monforts.de/en/latest-news-media/downloads/
