From the Sector

Monforts textile technologist Jonas Beisel will outline the benefits of the company’s Econtrol® continuous dyeing process during the next free-to-attend VDMA Textile Machinery Webtalk which takes place on February 3rd 2022 at 13.00 (CET).

“Our customers are increasingly looking at shorter production runs and the more economical use of dyestuffs, as well as reducing water and energy consumption,” says Beisel. “We have gained many years of experience in the optimisation of dyeing processes through working with our customers, both at their own plants and in our Advanced Technology Centre (ATC) in Mönchengladbach, Germany.

“Our Thermex universal hotflue for continuous dyeing, curing and thermosoling achieves unrivalled reliability even at high fabric speeds, for exceptional cost-effectiveness when dyeing both large and small batches of woven fabrics. The Econtrol® process for reactive dyestuffs now has an impressive number of references on the market, as a quick and economical one-pass pad-dry and wash off process. This is the ideal process for fast change technology and operational savings.”

Among key benefits are the saving of resources compared to conventional continuous dyeing methods, excellent reproducibility of pale to dark shades, from lab to bulk, and greater flexibility in production planning due to a resulting dry fabric that does not need an immediate wash off.

Econtrol® is a registered trademark of DyStar® Colours Distribution GmbH, Germany, and Bertram Seuthe of DyStar® will be providing recommendations for dyes and auxiliaries for the process during the VDMA event.

A third speaker, Guido Seiler of Fong’s Europe, will explain how Goller washing ranges help to significantly reduce the water that is conventionally wasted in the washing off process, through a combination of process and chemistry know-how and advanced technologies.

Denim manufacturers employing Monforts technologies showcased their latest activities, including sustainable fabric manufacturing, new advances in fibres, dyes and chemicals, as well as process and supply improvements and recycling options, at Première Vision’s Digital Denim Week, held from July 5-9.

The users of Monforts equipment included AGI Denim (Pakistan), Azgard 9 (Pakistan), Berto (Italy), Bossa (Turkey), DNM (Turkey), Kilim (Turkey) and Orta (Turkey).

The new Naveena Denim Mills (Pakistan) Holistic collection, for example, employs a suite of sustainable materials such as organic cotton and post-consumer and post-industrial waste cotton that has been shredded and recycled at its in-house unit in Pakistan.

Supply chain transparency is also becoming increasingly important, and Turkey’s Bossa is now sharing information on its dyes, energy sources and recycled content use with its customers. For organic cotton in particular, Bossa provides QR codes with which brands can identify the names of individual farms and their locations, as well as details such as the origins of specific seeds and the use of irrigation by growers.

Turkey’s Orta’s new Denim Route – inspired by the historical Silk Road for trade between the East and West – is an interactive supplier map detailing the regions from which it sources cotton, dyestuff, chemicals and various fibres to complement its other transparency initiatives.

Meanwhile, a living and breathing piece of clothing that absorbs carbon dioxide while simultaneously producing oxygen was introduced at Digital Denim Week 2021 by Azgard 9 (Pakistan) .

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.

• Major Monforts denim customers continue to pioneer new initiatives that are pushing the boundaries of sustainable production.

Recycling their cotton waste has become one way these companies can do more with less, and at the recent Kingpins24 Flash online event, Sedef Uncu Aki, director of Orta, headquartered in Istanbul, Turkey, announced a new partnership with leading recycling operation Gama Recycle.

Traceable
“Through this local partnership we will supply the waste from our spinning mills and return around 3,000 tons of premium quality cotton back to them,” she said. “We have established a truly controlled and traceable system and partnering with a domestic recycling centre is important because a lot the carbon emissions associated with recycling usually come from transportation.”

Orta’s ZeroMax range meanwhile uses no cotton at all, being based on Lenzing’s Tencel cellulosic fibre, while the company’s involvement in denim production for a recent launch by Levi Strauss, of jeans made with organic cotton and Circulose – a breakthrough material developed by re:newcell of Sweden and partners – was hailed as a further step forward.

To make Circulose, re:newcell repurposes discarded cotton textiles, such as worn-out denim jeans, through a process akin to recycling paper. The incoming waste fabrics are broken down using water. The colour is then stripped from these materials using an eco-friendly bleach and after any synthetic fibres are removed from the mix, the slurry-like mixture is dried and the excess water is extracted, leaving behind a sheet of Circulose. This sheet is then made into viscose fibre which is combined with cotton and woven into new fabrics.

Circular Park
Omer Ahmed, CEO of Artistic Milliners also announced plans for his company’s new 70,000 square-foot Circular Park in Karachi, Pakistan, at Kingpins24 Flash.

Once complete, this will add three million square metres of additional denim capacity a month to the company’s production and take its total recycled output to a monthly five million metres.
Ahmed observed that there is currently a lack of sustainable fibres that are readily available to use for denim production at scale.

“Organic cotton is too expensive, and in my opinion always will be,” he said. “Cottonised hemp is also not cheap and it’s hard to mix with cotton, while the new regenerated cellulose fibres that are now emerging are promising, but currently in short supply. Recycled polyester is meanwhile still based on petroleum resources which we want to move away from. As a consequence, there are only a few other options for us as a manufacturer and this new project will help us minimise our own waste while significantly lowering our carbon footprint.”

Other Monforts denim customers to introduce cotton fibre recycling operations at their plants recently include AGI Denim, Bossa and Soorty.

Vertical savings
Refresh is the name of the latest collection from AGI Denim – reflecting the company’s significant reduction in water consumption.

The company has just opened new fibre spinning and denim mills at its complex in Karachi, Pakistan.

“Over the years we’ve gone through a series of backward integration steps to become fully vertical,” said AGI Denim executive director Ahmed Javed, at Kingpins24 Flash. “In our latest expansion, we revisited every step of the production processes in order to make resource savings.”

Innovations have included the installation of proprietary robotics for garment finishing, but the most attention has been paid to water savings.

“Pakistan is one of the largest cotton-producing companies in the world and we’re fortunate that the type of cotton that is grown here is well suited to denim production and also helps us lower our carbon footprint, with everything done in close proximity,” Javed said. “In the lifecycle of a pair of denim jeans, however, cotton fibre production contributes 68% of water consumption. While we cannot control how much water cotton needs for it to grow, we can rethink the way we use it in our factory.”

Refresh-branded denims are washed from 100% recycled water as a result of the company’s new wastewater treatment plant, which puts production wastewater through a series of steps beginning with equalisation, followed by aeration and concluding with sedimentation. The water travels through filtration and ultrafiltration systems before being subjected to an activated carbon system and finally a reverse osmosis system to reduce any dissolved salts.

AGI now recycles 4.4 million gallons of water each month – enough to wash a million pairs of jeans.

Sustainable
Monforts has a leading position in the field of denim finishing with its well proven Thermex continuous dyeing systems, Montex stenter dryers and other lines for resource-efficient and economical processing.

“Our denim partners are constantly setting themselves new goals in respect of sustainable production – and more importantly, achieving them,” says Hans Wroblowski, Monforts Head of Denim. “We work closely with them with the aim of constantly optimising processing parameters and achieving further savings in energy, water and raw materials throughout the dyeing and finishing stages of production.”

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 integrates new functions and processes into the weaving preparation processes to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre in Mönchengladbach, Germany.”

• Leading Turkish textile printing company Hamle has installed a new Monforts Thermex dyeing range as part of its ongoing strategy of continuous investment.

“Investment in new technology and capacity expansions are very important to us, in order to stay ahead in terms of sustainable, high quality production,” says general manager Gürkan Uzuner. “We carefully assess the benefits of each advanced new technology in order to thrive in a sector that is constantly changing.

“The Zara Group is a major European customer for us, along with well-known Turkish brands such as LCW and De-Facto, and it’s no accident that Çorlu, due to its proximity to Istanbul and the ease of supplying to Europe, has become the epicentre of Turkish textile production. The quality of textiles coming from the region is now very well proven.”

Integration

Hamle’s plant in Çorlu already houses a Monforts ten-chamber Montex stenter and two Monforts sanforizing ranges on which the company carries out an extensive range of finishing processes. The new Thermex range further integrates a number of processes on technology all from a single supplier. The Thermex universal hotflue for continuous dyeing, condensing and thermosoling achieves unrivalled reliability even at maximum fabric speeds, for exceptional cost-effectiveness when dyeing both large and small batches of woven fabrics. The new range installed for Hamle benefits from the Econtrol® process* for reactive dyestuffs. This is quick and economical one-pass pad-dry and wash off process, with drying in the hot flue at 120-130°C and controlled humidity (25-30% by volume) to obtain fixation in 2-3 minutes.
Econtrol® ensures excellent reproducibility of all colours, improved dye penetration on difficult fabrics and no risk of the browning of cotton or other cellulose fibres due to the low fixation temperature.

As such, it is the ideal process for fast change technology and operational savings. “The new Thermex range has some very advanced automation features which ensure our machine operators have full control over the entire system,” Mr Uzuner concludes. “ As the Monforts representative in Turkey, Neotek has been our solution partner in the installation and commissioning and has been with us every step of the way.

Mission
On its mission to achieving continuous progress in error-free and resource-efficient manufacturing, İlay has just taken delivery of a new Monforts Montex stenter range, with a working width of two metres and eight TwinAir chambers.

“This installation provides us with much improved control options for all process parameters and compared to the old stenter it is replacing, we are particularly impressed with the energy savings we are making,” Mr Savaş says.

Achieving energy savings on Montex stenters has been a key focus for Monforts designers and engineers in Germany for many years.

With the TwinAir heating chamber system within a Montex stenter, top and bottom airflows can be regulated completely independently of each other, ensuring heat is only applied when and where it is required. The Optiscan balancing system ensures continuous automatic evaluation of the distance between the nozzles and the fabric for highly economical and contact-free drying.

The resulting constant evaporation rate within the stenter ensures optimum energy utilisation. In addition, TwinAir chambers feature special panelling for low heat radiation, careful sealing of all connecting positions and chamber access points, and air locks at both the entry and the exit.

“Monforts stenters set the benchmark in terms of energy efficiency and help conserve resources,” says Ahmet Kılıç, founder of Neotek, the representative for Monforts in Turkey. “Automatically setting the initial moisture content requirement for a specific process before drying to a minimum value helps reduce heat evaporation and consequently, energy consumption. The hermetic sealing of the stenter frame further prevents the loss of heated air as well as the ingress of excessive cold air – which has to be heated back up if it is not kept out in the first place.”

The new Montex line was completed at İlay Textile in August 2020, with no problems during either installation or commissioning.

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.

At a total length of over 71 metres, the Montex finishing line that has just been installed by Monforts for Acafintex at its plant in Puebla, Mexico, is one of the highest capacity stenters the German technology leader has delivered to date.

Puebla is known as the epicentre of Mexico’s textile and clothing industry and is ideally placed for supplying both the USA and Europe, being three hours from the Gulf of Mexico for shipping via the Atlantic, and five hours from the Pacific coast as well.

Mexico's textile and clothing industry spans the entire production chain – from cotton growing and man-made fibre production to the manufacture of yarn, fabric, finished clothing and accessories. The industry is estimated to directly employ around 640,000 workers and to provide livelihoods for many more people indirectly. The country is a key supplier of textiles and clothing to the USA, but has faced fierce competition from China, which has until recently been the largest supplier of textiles and clothing to the US market.

However, the position of Mexico in the US import market has become more stable following the signing of the United States-Mexico-Canada Agreement (USMCA), which came into force in July this year. The country has also been a key beneficiary of the current trade war that is raging between China and the USA.

In addition, there is scope for higher sales in Mexico’s domestic market. The country has a population of 129 million people who are becoming increasingly prosperous, with a large proportion of younger people who are spending more on clothing.

Flexible operation

Founded in 1986, family-owned Acafintex operates as a commission dyehouse, finishing both knitted and woven fabrics for local companies in Mexico, in widths of between 100cm to 3.6 metres. The company is run by father and son team Don Francisco and Lic Francisco Moyano.

“We have very flexible operations for fabric finishing and also produce and sell our own fabrics for both the fashion industry and for the uniforms market,” says Don Francisco. “These days, we are increasingly finishing materials for technical textiles and for the automotive industry too. We have both local and international suppliers of both yarns and base fabrics and make sure we choose the best and most reliable sources. Exports now account for over 40% of our sales.”

European contract

With a  width of 3.8 metres, the new Monforts Montex line at Acafintex is equipped with no less than 12 double TwinAir drying chambers to meet the requirements of specific technical textiles to a European customer, in a contract secured following the company’s ISO 9001 certification in 2019. The line is equipped with an integrated heat recovery system and also benefits from an exhaust air cleaning system to ensure the most resource-efficient processing available on the market.

On the Monforts TwinAir system, the airflows above and below the fabric being dried can be regulated completely independently of each other, with Optiscan Auto-Balance fully controlling the distance between the fabric and the dryer nozzles via variable-frequency fan motors and CCD chip evaluation. As a result, the evaporation rate of the stenter and its energy utilisation are always fully optimised. Contact-free drying eliminates the possibility of fabric marking or stitch draft.

Highly-intuitive Monforts Qualitex visualisation software allows all machine functions and process parameters to be assessed and controlled easily, and thousands of article specific settings and formulations to be called up at any time – with 100% reproducible results.

In combination with an existing Montex stenter, the new line has expanded finishing capacity at Acafintex to an annual 20 million linear metres.

Modifications

“From the installation to the start-up, we were supported by a team of Monforts technicians and local representative Arnulf Thaler at Sattex here in Mexico,” says Lic Francisco. “Of course, every installation has its challenges and with such big machines we needed to modify several things inside the factory and also required certain modifications from Monforts which were all carried out successfully.”  

Forced, like much of the textile industry globally, to temporarily suspend operations at the height of the Covid-19 pandemic, Acafintex is now back to full production, having installed the necessary safety measures for its employees, and is anticipating a bright future.

“We are passionate about developing new materials in search of mutual benefit for both our clients and suppliers, as well as our own workforce and the environment,” Don Francisco Moyano concludes. “Investment in the latest technology like this new Monforts line plays a key role in helping us achieve our long-term goals.”

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.

In the current fight against Covid-19, a number of formulators of textile finishing chemicals have rushed out new antiviral and antimicrobial treatments intended for PPE (personal protective equipment) such as face masks and medical gowns and drapes.

These finishing chemicals have naturally already been thoroughly tested in laboratories and their effectiveness verified at laboratory or pilot scale. However, they are new to many manufacturers of textiles and nonwovens now preparing to use them on an industrial level.

A lot of companies changed, due to the current situation their usual manufacturing programmes to the production of PPE items. “We have experts on hand at our operational Advanced Technology Centre (ATC) here in Germany, to help any of our customers to rapidly transition to new finishing techniques and treatments they may not be familiar with, and to run trials on their behalf, should they require this assistance.”, states the vice president of Monforts, Klaus Heinrichs.

The three lines at the ATC situated at the Monforts HQ in Mönchengladbach, are of a true industrial scale and trialling new products on them goes beyond lab or pilot plant testing to rapidly identify any problems that might occur once full production is underway.
