From the Sector

In a roundtable discussion during the recent Innovate Textiles & Apparel (ITA) textile machinery exhibition, imogo Founding Partner Per Stenflo and representatives from a number of like-minded European companies discussed the opportunities for new spray application technologies for the dyeing and finishing sector.

These technologies can achieve tremendous savings for manufacturers compared to traditional water-intensive processes it was explained at the event, held online from October 15-30th.

Pioneer
imogo – one of the latest companies to join TMAS, the Swedish Textile Machinery Association – is one of the key pioneers in this area with its Dye-Max system. Dye-Max spray dyeing technology can slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems. This is due to the extremely low liquor ratio of 0.3-0.8 litres per kilo of fabric and at the same time, considerably fewer auxiliary chemicals are required to start with.

Obstacles
Such technologies, however, face a number of obstacles to adoption and during the ITA discussion it was agreed that 2020 has not provided the ideal climate for adventurous investors. “The textile industry is quite conservative and is definitely in survival mode at the moment and it is not the time to be a visionary,” said Stenflo. “Day to day business is about staying alive – that’s the reality for many of our customers.” Nevertheless, all of the panellists agreed that sustainable production will remain top of the agenda for the textile industry in the longer term and spray technologies for dyeing and finishing processes will be a part of it.

“Any investment in something new is a risk of course, and we have to be able to explain and convince manufacturers that there’s a good return on investment, not only in respect of sustainability, but in terms of making good business sense,” said Stenflo. “Here we could use the help of the brands of course, in putting pressure on their suppliers to be more sustainable. Governments also have a role to play, in providing incentives for producers to move in the sustainable direction. Sustainability alone will never cut it, there has to be a business case, or it won’t happen.”

Marketing
The marketing of sustainable new fibers is comparatively easy for the brands compared to explaining the difficult textile processes and the chemistries involved in fabric and garment production, he added.

“These fibers, however, currently go through all the same dirty processes that we need to get away from, so it must happen,” he said. “In developing our technologies, it has been important for us to avoid disrupting existing supply chains, stick with using off-the-shelf chemistries and dyes, and involve the dye manufacturers who are an essential part in how operations are driven today. “In fact, collaboration across the entire textile supply chain – from the brands right back to the new technology developers – is essential in moving the sustainability agenda forward.

Business models
“We are also looking into new business models in terms of how to reduce or lower the thresholds for investment and minimise the risk for the manufacturers who are looking to be the innovators,” he concluded. Also taking part in the ITA roundtable discussion were Simon Kew (Alchemie Technology, UK), Christian Schumacher (StepChange Innovations, Germany) Tobias Schurr (Weko, Germany), Rainer Tüxen (RotaSpray, Germany) and Felmke Zijilstra (DyeCoo, Netherlands).

European innovations
“It’s fantastic that all of this innovation is taking place in Europe based on established know-how and forward thinking,” said TMAS Secretary General Therese Premler-Andersson.

“Spray application technologies are a perfect illustration of how new digital technologies can lead to more sustainable production, in this case by replacing water-intensive processes with the highly precise and controlled application of dyes and chemistries as vapour.
“There was a major project by the Swedish research organisation Mistra Future Fashion recently, involving many brand and academic institute partners. The project’s Fiber Bible 1 and 2 reports conclude that it’s very difficult to make assumptions that one fiber is better than another, because it’s so much about how fabrics and garments are being produced from them. The study also found that 55% of the chemicals used in a garment comes from the dyeing. This is where a number of TMAS companies can make a difference.
“An organic or recycled cotton t-shirt is not automatically more sustainable than a conventional cotton t-shirt, or even one made from synthetics – the alternative fibers are a good start but you have to consider the entire life cycle of a garment, and that includes the smart technologies in textiles production.
“TMAS members – backed by Swedish brands and advanced research institutes – are playing an active part in pushing forward new concepts that will work, and I have no doubt that digitalisation now goes hand in hand with sustainability for the textile industry’s future.”          

At first glance, rowing boats, the Airbus 380, safety equipment and stadium roofing have very little on common. They receive their specific properties as a result of the use of special fibers, among other things: aramid fibers and carbon fibers are processed into special yarns that are frequently deployed as compound materials. These fibers are growing in demand as the world seeks to reduce its reliance on fossil fuels; new solutions are required to reduce weight and replace heavy metallic parts.

Aramid fibers are produced in a highly-chemical process that is extremely aggressive; the acrylic precursor used to manufacture carbon fibers is a different process, but again no less difficult. In these sophisticated processes, the gear metering pumps are not only responsible for the high-precision control of the melt transport; durability, resistance within aggressive environments and cost efficiency also play decisive roles.

Special materials for special tasks
The process, the expected pump lifespan and the maintenance frequency are the decisive factors for choosing the materials from which the pumps and their components are manufactured. For optimum results, Oerlikon Barmag offers solutions that intelligently combine the various materials and the latest technologies. Whether in the case of surfaces with ceramic coatings, gears and shafts featuring DLC coatings, pumps made from cobalt alloys (StelliteTM) or robust and durable Oerlikon Barmag hybrid constructions comprising zirconium oxide ceramic and duplex stainless steel – the high-precision ZP- and GM-series pumps are design-optimized depending on the intended use. Various seal systems and customized drive concepts round off the pump program.

• Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, today announced that, for the first time, Dyneema® Composite Fabrics are used by Moncler in the Fall/Winter 2020 Grenoble collection, which fuses form and function into high performance skiwear.

Moncler Grenoble is born of a passion for research and implements cutting-edge technology to push the limits of its potential. The design team identified Dyneema® as an innovative fabric it could use to push the level of its performance to the next peak, incorporating the material into the new collection as a departure from the conventional use of cotton and polyester.

Sandro Mandrino, the Head of Design for Moncler Grenoble, was the first designer of the luxury fashion brand to incorporate Dyneema® into one of his creations through the Moncler Genius project. The Moncler Genius project advocates radical co-creation where multiple designers create their own signature collections in collaboration with the house. Together, these collections translate into one vision of the future and, as one of the nine designers, Mandrino’s interpretation of the future of fashion features Dyneema® Composite Fabric.

Using variations of the fabric in both white and black allowed Mandrino to bring his vision to life by merging skiwear, space suits and technology all in one. “ 3 Moncler Grenoble is first and foremost about performance,” states Mandrino, who integrated constructive solutions with fabric technology to develop a line that was meant to perform both on and off the ski slopes.

Dyneema®, the world’s strongest and lightest fiber, is 15 times stronger than steel yet light enough to float on water. The unmatched performance and protection of products made with Dyneema® have made it the material of choice in critical applications where failure is not an option for more than 30 years. In fabric form, Dyneema® is available in composites, denim, knits, wovens and hybrids for composite reinforcements. And because Dyneema® fabrics are made using Dyneema® fiber, they intrinsically provide high strength, low weight, waterproof and breathable properties – allowing designers to fuse the technical performance of ultra-light products with aesthetic design that doesn’t sacrifice strength or durability.

The Moncler team used the Grenoble collection as an opportunity to experiment and further understand the nature and behavior of Dyneema® fabrics, while simultaneously incorporating material performance with practical design. “Future collections will focus on expanding to new designs and fabric options in collaboration with DSM,” adds Mandrino.

“We are very excited to be working with the Moncler team to launch a collection of wonderful garments that allow people to explore the outdoors more safely and for longer periods of time,” states Marcio Manique, Global Business Director, Consumer & Professional Protection, DSM Protective Materials. “We look forward to further supporting Moncler as they develop innovative, high-tech garments that are also sustainably sourced through the introduction of bio-based Dyneema® fabrics.”

In line with DSM’s commitment to protect people and the environment they live in, the world’s first-ever bio-based ultra-high molecular weight polyethylene fiber was introduced in May 2020. Bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE. DSM and Moncler’s continued partnership will not only provide high performance, light weight garments for outdoor enthusiasts but also environmentally sustainable alternatives that contribute to a more circular economy.

• On October, 20th, 2020, the State Prize for Innovation was awarded to the Lenzing Group for their LENZING™ Web Technology.
• Lenzing thus received the highest award for particularly innovative achievements in Austria.

Lenzing – On Tuesday, October 20, 2020, the Lenzing Group was awarded the coveted “State Prize for Innovation”. Lenzing emerged as the winner with its project LENZING™ Web Technology and thus received the highest recognition for particularly innovative achievements in Austria. The novel process combines fiber and nonwovens production in only one step, setting new standards in terms of efficiency, circularity and ecological sustainability. Margarete Schramböck, Federal Minister for Digital and Economic Affairs, presented the award to Gert Kroner, Vice President Global Research & Development.

“This award is a great recognition of our work. Our goal is to grow continuously with sustainable innovations and to look beyond our fibers, to the needs of our customers and partners and to the needs of consumers worldwide. With the LENZING™ Web Technology we have created an exciting and promising solution for eco-friendly products in line with our corporate strategy sCore TEN and support consumers in their daily needs in a sustainable way”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group.

Biodegradable nonwovens for a clean environment

The pollution of the environment by plastics is one of the most urgent problems of our time. Every day, millions of hygiene products and wipes around the globe end up in garbage and sewage. Most of them consist of up to 80 percent polyester or other fossil, non-biodegradable materials and therefore pollute the environment. With the LENZING™ Web Technology, Lenzing has developed a patented technology to counter this problem: Sustainable and eco-friendly nonwovens are produced from the renewable raw material wood. These are not only plastic-free, they also score points for their particularly high environmental friendliness. “Thanks to a unique self-bonding mechanism, in which the filaments bond with each other during the spinning process, binders, which are found in many nonwovens, are no longer needed. As a result, the nonwovens produced with LENZING™ Web Technology are 100 percent biodegradable and do not pollute either humans or the environment”, says Gert Kroner, Vice President Global Research & Development of the Lenzing Group.

The Austrian State Prize for Innovation is awarded annually by the Federal Ministry for Digital and Economic Affairs to the most innovative Austrian company. In 2020, the competition took place for the 40th time.

The Cetex Institut gGmbH, the thermoPre ENGINEERING GmbH and The FilamentFactory GmbH cooperate in the development, production and marketing of novel hybrid materials. The cooperation agreement signed on October 2, 2020 in Chemnitz takes the collaboration to a new level. "We are pleased to be able to supply the hybrid rovings to the end user not only in an application-specific manner, but also to offer the engineering for subsequent component applications, including the prototyping of the FRP components," says Sebastian Nendel, Managing Director of Cetex.

Patented process for the production of hybrid rovings
In the last 3 years the Cetex Institute has developed a plant technology for the production of hybrid rovings. By means of the patented process, different material combinations can be produced according to customer specifications. Material combinations of reinforcing fibers (glass, basalt, carbon, aramid or high-strength polymer fibers) can be combined with matrix fibers (PP, PET, PA, PPS, PEEK), but also special combinations of different reinforcing fibers or the combination of reinforcing fibers with metal fibers. Advantages of the new hybrid roving are the torsion-free and completely stretched fiber layer and the associated optimal utilization of the properties of the reinforcing fibers, as well as a very good homogeneity, whereby excellent processing can be achieved in later process steps.

Series production as next step
The next goal is clearly defined: Under the agreement, the process is to be jointly developed further by the project partners and transferred to series production. These joint activities form the basis for many years of intensive cooperation in this new field.

“When it comes to working on new developments, we always start from new ideas and the constant research that starts from a concept that becomes reality, by increasingly raising the bar of sustainability” said Alice Tonello, R&D and Marketing Director of Tonello. “The research for technologies and solutions have always been part of our DNA, is a daily commitment to the environment, the market, our people and all human beings with their needs.  Based on this vision, two revolutionary patent-pending process, are born, Wake and OBleach, that allow to create incredible and totally responsible effects on garments” continued Alice Tonello.

This is how The Laundry (R)Evolution was born: a radically new conception thought to simplify and optimize the entire garment finishing process.

It involves only 2 technologies in the entire finishing cycle, reducing waste and optimizing resources: LaserBlaze, and The All-in-One-System. Metro is used, a software that processes real data, in real time to check all laundry consumption, optimizing processing times and improving performance.

The All-in-One System performs all washing operations by integrating 4 sustainable technologies into a single machine: ECOfree 2, which uses ozone in both the water and air; NoStone® for authentic and pumice-free stone-wash effects; UP, for washing processes with at least 50% less water; Core, a nebulizing system improving performance and reducing water consumption.

In terms of effects, the latest results of the Laundry (R)evolution are OBleach and Wake.

OBleach is the new Tonello patent-pending process which, by using only ozone, “returns to the future” with an authentic, sustainable and cool Bleach.

Wake is the first totally natural dyeing system. In fact, it uses only plants and vegetable waste, organic items like flowers, berries and roots left to dry and infuse, without harmful chemicals additives.

Tonello will be live during DenimsandJeans Virtual Show on October 14th and 15th.

• World Cotton Day on 7 October Highlights the Importance of Cotton for Development Policy

Bremen - Stemming from a 2019 initiative of the African Cotton-4 countries Benin, Burkina Faso, Chad and Mali, World Cotton Day will take place this year on 7 October. The event is organised by the Geneva-based World Trade Organisation (WTO) and is supported by the Food and Agriculture Organisation of the United Nations (FAO), the United Nations Conference on Trade and Development (UNCTAD), the International Trade Centre (ITC) and the International Cotton Secretariat (ICAC). The Bremen Cotton Exchange is also involved.

“Cotton is often underestimated because it is so natural. Behind it are millions of people, for example many farmers, field workers, employees in ginning factories, logistics providers and traders. We want to honour their achievements,” said the President of the Bremen Cotton Exchange, Stephanie Silber.

According to the WTO, the aim of World Cotton Day is to highlight the global economic importance of cotton and to raise awareness of the raw material by recognising the work of everyone involved in its cultivation, processing and trade. At the same time, within the framework of international cooperation, it is hoped that supporters and investors can be found to aid with technological and economic progress within the cotton value chain.

This time, the entire world cotton community will be involved in World Cotton Day on Wednesday, 7 October 2020. A wide variety of campaigns and events are taking place everywhere to draw attention to the importance of cotton and its possible uses.

Cotton is one of the most relevant agricultural raw materials in the world. Around 26 million tonnes of it are harvested annually. Approximately 150 million people in almost 80 countries around the world live from the cultivation of the natural fibre. A large number of these live in developing countries, where cotton cultivation is of particular importance as a cash crop.

Cotton is known as an agricultural product that is turned into a textile. The raw material is indispensable in fashion and clothing – and has been for thousands of years. But the use of cotton now goes far beyond textiles. For example, cosmetic products such as hand creams and hair shampoo are made from the oil of cotton seeds. The raw material is also used in the manufacture of banknotes, furniture and technical textiles, as well as in medical technology.

Against the background of the current discussion on sustainability and sustainable consumption, the role of natural fibres is becoming even more important. Cotton is biodegradable and a renewable resource. It can be grown again and again in agriculture through cultivation in crop rotation. This secures incomes and enables efficient value creation within the global production and processing chain.

The Bremen Cotton Exchange will actively support World Cotton Day with cross-media coverage. In addition, in time for World Cotton Day, three thematically different, emotionally appealing short films about cotton will be launched. They are aimed at consumers as customers of the textile and clothing trade and provide information about the benefits and properties of cotton and answer questions about its sustainability. In keeping with the times, they will be published via virtual media.

Retrofitting a wiping robot to spinning systems is well worthwhile. This is confirmed by the experiences of those customers who have already installed the wiping robot. Oerlikon Barmag wiping robots have been cleaning spin packs at filament yarn manufacturing facilities in China and India for several months now, increasing efficiency considerably.

Regular wiping of the spin packs is important for process stability and yarn quality. These can be positively influenced using wiping robots, because – as confirmed by data acquisition and analysis at the respective manufacturing facilities – the yarn break rate can be reduced by up to 30% by automating the wiping process. And the yarn break rate has a direct impact on the key production figures; to this end, a considerable reduction translates into pure profit for yarn manufacturers.

Can also be retrofitted to existing systems
The Oerlikon Barmag wiping robot can be retrofitted to numerous spinning plants. Suspended from a track system mounted on the ceiling, the system automatically and autonomously targets the individual positions in accordance with the scheduled wiping cycles. In addition to the scheduled wiping processes, there are also events that cannot be planned or that are not immediately visible. Depending on the degree of integration into Oerlikon Manmade Fibers Smart Factory solutions, the wiping robot is able to identify issues such as yarn breaks or parallel wiping processes and to independently offer solutions.

The wiping robot operates in a cross-line manner. Here, the wiping quality remains constant 24/7. The high wiping quality has a positive influence on both the stability of the overall process and on the yarn quality. The time saved between cleaning cycles is a further advantage: using the robots, the interval between two wiping processes can be extended by up to 25%. The considerable increase in the spinning process efficiency achieved by the wiping robot also has a positive impact on margins. For example, one customer deploying the wiping robot was able to reduce its production costs for the same yarn by more than 3%.

• 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.”
