From the Sector

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.

The textile machinery industry is eagerly awaiting the start of the virtual trade show "Innovate Textile & Apparel". What and how will the more than 160 exhibitors present themselves virtually? How will the approximately 10,000 registered visitors accept the digital offer? WTIN is breaking new ground as organizer with this platform. But one thing is already certain: From 15 to 30 October 2020, they will bring the textile machinery industry a little closer together again in the Corona Pandemic. Oerlikon invites all visitors to take a look into the future of manmade fibers production and get to know the comprehensive range of products and services.

"Reconnecting innovation in the textile & apparel value chain" is the motto of WTIN's virtual trade show. And Oerlikon intends to more than live up to this motto. With more than 50 active experts from sales, customer service and technology as well as partners from its international network of representatives, the Manmade Fibers segment of the Swiss Oerlikon Group will try to be represented around the clock. "It is an interesting experiment for all of us and we would like to see it succeed," explains André Wissenberg, Head of Marketing, Corporate Communications and Public Affairs. "Our aim is to meet our existing customers again, make new contacts and see 'old friends' from the industry. We have prepared an attractive digital offer for them all. Those of you who missed our roller coaster ride in Barcelona last year can now enjoy the journey through time in peace and quiet from your home office on your digital tour of the fair. And, there are no more waiting times either," promises Wissenberg.

Factory know-how from a single source
From Melt to Yarn, Fibers and Nonwovens. From the polycondensation and the processing of PTA and MEG as well as the extrusion of, for example, recycled polyester chips all the way through to hundreds of thousands of packaged and stored or directly-delivered textured bobbins for a market within the textile industry worth billions. From the planning and construction of highly complex production plants to the engineering of large-scale plant projects and competent customer services. This business model runs like a red thread through the self-conception of the Manmade Fibers segment of the Swiss Oerlikon Group. The right partner, especially – but not exclusively – for newcomers to the textile industry. "With us they get everything they need for a successful business: Factory know-how from a single source. And that's what we would like to show our visitors at our virtual trade fair booth," says Wissenberg.

Sustainability and environmental responsibility are important developments for the current design of productions and products. In order to obtain a comprehensive evaluation of the potential of bio-based composites, the AZL, together with an industry consortium, is investigating the market potential, future applications and relevant technologies for bio-based composite materials. The 5-month market and technology study will start on October 22nd, 2020 and is open to interested companies. Companies such as REHAU, an Automotive Tier 1, Asahi Kasei, Johns Manville, Mahr Metering Systems and several material manufacturers are participating in the study.

Bio-plastics are well established in industry, especially in packaging applications. The market for biopolymers is expected to grow from USD 10.5 billion in 2020 to USD 27.9 billion in 2025. At the same time, bio-based raw materials, such as natural fibers, are available on the market in a cost-effective manner. Composites with wood or natural fiber content are also increasingly used in products.

Dr. Michael Emonts, Managing Partner of AZL: "Together with our partner companies we want to identify hidden business potential for composites with bio-based materials. To do so, we will reapply our established approach for market and technology studies: Based on a detailed market analysis, we will dive deep into the technological evaluation of technologies, applications and business cases.”

Based on a detailed market segmentation, AZL's technology experts analyze the various market segments in terms of their size, growth potential, relevant players and existing and future applications. For the identified applications, the participants in the study will receive detailed insight into the respective technical and legal requirements as well as an overview of value chains, processes and materials. In the following, the strengths and challenges of bio-composites compared to conventional materials are elaborated. The consortium will select the components with the highest potential, for which suitable production scenarios will be developed and analyzed in terms of costs in a business case analysis.

"We are participating in the AZL study to identify and evaluate new product areas with bio-materials. The technological analyses of the AZL studies have already helped us in the past to initiate new developments," says Dr. Steven Schmidt, Director Technology Platforms Materials at REHAU, explaining the motivation for working with the AZL and the industry consortium. "As one of the 50 Sustainability & Climate Leaders, we at REHAU are incorporating environmentally friendly materials into more and more products. Wherever the company is active - from the furniture and construction industries to the automotive industry - REHAU is already developing and manufacturing high-quality products from recycled raw materials. By 2025, REHAU plans to increase its recycling rate across the Group to significantly more than 15 percent and at the same time reduce CO2 emissions by at least 30 percent," adds Dr. Steven Schmidt.

Bio-composites will also be the topic of the upcoming Lightweight TechTalk by AZL on September 29, 2020. Experts from industry and academia will give technology and market insights on sustainability and recycling of composites in 6 presentations. Registration is free of charge at: https://azl-aachen-gmbh.de/termine/recycling-of-composites/.

The kick-off of the project will take place on October 22nd, 2020 in the form of a video conference. Further background information on the project can be found under the following link: https://azl-aachen-gmbh.de/wp-content/uploads/2020/09/2020-251_OP_Bio-Bases_Composites.pdf

Martin Hornig has taken over the position of Vice President Service & Solutions at Winkler+Dünnebier GmbH (W+D) on September 1, 2020. He reports directly to the management.

In his new role, Mr. Hornig will manage W+D's worldwide service activities. Before that, he was Head of Sales and Service at well-known German mechanical engineering companies. Martin Hornig has extensive specialist knowledge in the areas of services, after sales and project management.

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, has joined hands with Liberty Textile Mill Limited (Liberty), a leading producer in healthcare textiles to produce high quality personal protective equipment (PPE).

Liberty will be benefitting from Archroma’s specialty solutions for hygiene protection, and well-established technical expertise in the area of medical textiles. Amidst the COVID-19 pandemic, the PPEs manufactured by Liberty are aimed at easing the current shortage of PPEs for medical professionals in Pakistan.

Liberty carries over two decades of experience in medical textiles and exporting them all over the world. Its partnering with Archroma is a major step forward towards creating enhanced protection in the current crisis. With its advanced scientific knowledge and technical expertise, Archroma provides a complete set of specialty chemicals required to produce PPEs, in particular in the area of antimicrobial and barrier coatings. The project will assist in enhancing medical standards in hospitals, isolation centers and intensive care units, in Pakistan and, very soon, worldwide.

“By continuously challenging the status quo, we at Archroma are able to support our customers operating in or entering the area of medical textiles, with a holistic and expert approach to hygiene protection. With our collaboration with Liberty, we are so proud to be able to bring state-of-the art protection to health professionals and the general public,” comments Mujtaba Rahim, CEO of Archroma Pakistan.

“Liberty has a presence of more than five decades with high achieving accolades. Our processing units are fully equipped with latest equipment complying with international standards. We take this new partnership with Archroma as a start of building a strong relationship in the area of medical textiles. The COVID-19 pandemic has given a wake-up call to work extensively towards enhancing healthcare facilities. We are looking forward to new innovations in producing top-class PPEs,” adds Taimoor Mukaty, Director of Liberty Textile Mills Limited.

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.

• Technical Absorbents Limited (TAL) has developed a new grade of superabsorbent fibre (SAF) specifically for use within a new range of SAF nonwoven fabrics that are more resistant to shrinkage.

The new SAF was developed in response to the demand from the medical industry for a superabsorbent fabric suitable for use in advanced wound pad dressings. The fibre had to be capable of withstanding the moisture used in the EtO sterilization process that is frequently employed in the production of the pads, in order to ensure product safety and compliance.

EtO sterilization is a low-temperature process (typically between 37 and 63°C) that uses ethylene oxide gas to reduce the level of infectious agents. While generally applied in gas form, however, the EtO is usually mixed with other substances – and often steam.

“Obviously superabsorbents and moisture generally aren’t a good combination at this stage in processing and can cause problems,” says TAL Product Development Director Dr Mark Paterson. “Other methods can be used, but when silicone materials are included, which is more frequently becoming the case, EtO is the preferred treatment method. Regular SAF grades tend to shrink a little and can become hard, which is often not desirable. This innovative SAF grade significantly reduces such potential problems.”

The amount of shrinkage caused by EtO sterilization depends very much on the product design and construction, he adds, but in general, the new SAF has been tested and proven to reduce fabric shrinkage by around 70%. It is suitable for use in all SAF nonwoven formats, whether needlepunched, thermally bonded or airlaid.

While the proprietary process developed at TAL for the production of this new fibre and resulting fabrics was prompted by the specific requirements of wound pad dressings, TAL sees opportunities for its application in other areas as well.

“It’s an extremely flexible fibre that can be easily switched with existing SAF grades when manufacturing fabrics and we have a number of current projects in which we’re exploring other end-uses,” Mark concludes. “We believe this new range could also open up entirely new application areas on the market.”

• Members of TMAS – the Swedish textile machinery association – have adopted a range of new strategies in response to the Covid-19 pandemic, aimed at assisting manufacturers of textiles and apparel to adjust to a new normal, as Europe and other regions emerge cautiously from lockdown.

“Many European companies have been forced into testing new working methods and looking at what it’s possible to do remotely, and how to exploit automation to the full, in order to become more flexible,” says TMAS Secretary General Therese Premler-Andersson. “Others have been taking risks where they see opportunies and there’s a new sense of solidarity among companies.

“It’s extremely encouraging, for example, that over five hundred European companies from across our supply chain are reported to have responded to the shortages of facemasks and PPE – protective personal equipment – by converting parts of their sites or investing in new equipment.”

New supply chains

Amongst them are TMAS members of the ACG Group, who quickly established a dedicated new nonwovens fabric converting and single-use garment making-up plant to supply to the Swedish health authorities. From a standing start in March, this is now producing 1.8 million square metres of converted fabric and turning it into 692,000 finished medical garments each month.

“In 2020 so far, we have seen new value chains being created and a certain amount of permanent reshoring is now inevitable,” says Premler-Andersson. “This is being backed by the new funding announced in the European Union’s Next Generation EU plan, with €750 billion marked for helping industry recover. As the European Commission President Ursula von der Leyen has stressed, “green and digital” transitions hold the key to Europe’s future prosperity and resilience, and TMAS members have new solutions to assist in both areas.”

Remote working

Automated solutions have opened up many possibilities for remote working during the pandemic. Texo AB, for example, the specialist in wide-width weaving looms for the paper industry, was able to successfully complete the build and delivery of a major multi-container order between April and May.

“Our new Remote Guidance software now makes it possible for us to carry out some of the commissioning and troubleshooting of such new lines remotely, which has been helpful” says Texo AB President Anders Svensson.

Svegea of Sweden, which has spent the past few months developing its new CR-210 fabric relaxation machine for knitted fabrics, has also successfully set up and installed a number of machines remotely, which the company has never attempted before.

“The pandemic has definitely led to some inventive solutions for us and with international travel currently not possible, we are finding better methods of digital communication and collaboration all the time,” says Svegea managing director Hakan Steene.

Eric Norling, Vice President of the Precision Application business of Baldwin Technology, believes the pandemic may have a more permanent impact on global travel.

“We have now proven that e-meetings and virtual collaboration tools are effective,” he says. “Baldwin implemented a home office work regime from April with only production personnel and R&D researchers at the workplace. These past few months have shown that we can be just as effective and do not need to travel for physical meetings to the same extent that was previously thought to be necessary.”

Pär Hedman, Sales and Marketing Manager for IRO AB, however, believes such advances can only go so far at the moment.

“Video conferences have taken a big leap forward, especially in development projects, and this method of communication is here to stay, but it will never completely replace personal meetings,” he says. “And textile fabrics need to be touched, examined and accepted by the senses, which is impossible to do via digital media today. The coming haptic internet, however, may well even change that too.”

Social distancing

The many garment factories now equipped with Eton Systems UPS work stations – designed to save considerable costs through automation – have meanwhile benefited from the unintentional social distancing they automatically provide compared to factories with conventional banks of sewing machines.

“These companies have been able to continue operating throughout the pandemic due to the spaced nature of our automated plant configurations,” says Eton Systems Business Development Manager Roger Ryrlén. “The UPS system has been established for some time, but planned spacing has proved an accidental plus for our customers – with improved productivity.”

“Innovations from TMAS member companies have been coming thick and fast recently due to their advanced know-how in automation concepts,” Premler-Andersson concludes.  “If anything, the restrictions imposed by the Covid-19 pandemic have only accelerated these initiatives by obliging our members to take new approaches.”
