From the Sector

In the joint project "AeroFurnace" funded by the German Federal Ministry of Economic Affairs and Energy (BMWi), the consortium, consisting of the Bavarian Center for Applied Energy Research e.V. (ZAE Bayern) as joint coordinator, the furnace manufacturer FCT Systeme, and SGL Carbon has succeeded in improving the thermal insulation properties of a new composite material by up to 120 percent compared to commercially available felt-based carbon materials. This enabled the project partners to move into a new quality level of thermal insulation in high-temperature industrial applications and pave the way for more energy efficient thermal insulation.

Dr. Gudrun Reichenauer, coordinator of the joint project and head of the work group Nanomaterials at ZAE Bayern: "In this project, we have been able to make the latest findings from the world of nanomaterials accessible to the market through intensive cooperation and thus set new standards in the field of thermal insulation materials."

Dr. Thomas Kirschbaum, project manager at SGL Carbon: "In furnace simulations at the partner FCT, we have already been able to demonstrate what the new material can do: Depending on the temperature program, up to 40 percent of the required process energy can be saved with the new thermal insulation material. The potential of the new material is great." This prediction will be reviewed under real conditions in a demonstrator component in the second half of 2020 as part of the still ongoing BMWi project.

Dr. Jürgen Hennicke, project lead and head of R&D at FCT Systeme: "As a leading manufacturer of industrial vacuum or inert gas high temperature furnaces, the new generation of insulating materials enables us to create furnaces with a more favorable ratio of usable space to external dimensions, thus offering customers improved cost efficiency and productivity".

Based on laboratory samples in plate form it has already been demonstrated that the production of the new material can be represented by technically simple processes and is in principle well scalable. However, there is still a long way to go before the product is ready for serial production.

The third largest share of final energy in Germany is used for the generation of heat in industrial processes (22.6 percent). In many industries, e.g. in the steel and ceramics industry, energy-intensive high-temperature processes run above 1000°C – these alone require almost 50 percent of the industrial process heat. Suitable thermal insulation materials can significantly reduce energy demand while maintaining the same usable volume.

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.”

• Specialised in dye-sublimation printing, the Italian company has conquered the heights of the high fashion sector with its top-quality printed fabrics.
• With its recent investment in a direct-to-fabric printing line, Digitak is preparing to expand its range of printed products, focusing on fabric differentiation.

Dye sublimation printing of high fashion designs is the beating heart of Digitak, an Italian company specialised in digital textile printing. Operating in the textile district of Lombardy, Italy, the company has established itself among the main suppliers in the world of high fashion and sportswear in just under 15 years.

Making production versatility one of the cornerstones of its philosophy, Digitak has continued to invest in technology, as well as research and development its product portfolio. This forward-thinking approach has enabled the company to guarantee innovative, personalised products with meticulous attention to detail, with the highest – almost obsessive – standards of quality and maximum design flexibility. Over the years, the extensive experience gained by the company’s management in the field of sublimation with traditional and digital techniques, combined with their investment decisions have allowed Digitak to enhance its production performance, gradually implementing higher quality standards and differentiating itself from the competition in the complex and competitive sector of high fashion. An important feat, which has not, however, dampened its enthusiasm and willingness to continue growing and exceeding its goals. The company’s latest investment in a direct-to-fabric digital printing line with pigment ink propels the company into a new and promising production dimension.

Sublimation printing specialists

Since Digitak’s establishment, Filippo Taccani, the founder and current owner of the company, had set himself a clear and ambitious objective: “I wanted to take up the challenge of operating digitally - printing fabrics using this innovative technology to create products on a par with those  I had achieved with traditional sublimation textile printing methods during my previous work experience.”

The purchase of a Mimaki JV4 plotter, one of the first to be installed in Italy, marked the beginning of Digitak’s adventure. “To start the business, I needed a printing system that could operate with dispersed inks to print on polyester and I found the JV4 to be the best option,” explains Taccani. “It was an excellent decision, because I used these plotters to build the company and its success.”

The first Mimaki plotter was in fact followed by a second and a third. When it bought the fifth, the company moved to an industrial unit in Tradate (Varese) – Digitak’s current site – which now houses around fifteen Mimaki JV33 plotters, in addition to three Mimaki TS500-1800 wide-format sublimation printers, and a Mimaki TS300P-1800 high-speed sublimation printer. This Mimaki powered production facility – which is one of the company’s core strengths – was recently expanded with the addition of a Mimaki TX300P-1800B belt-type hybrid printing system, together with a Mimaki TR300-1850C textile coater and a Mimaki Tiger-1800.

“Naturally, over the years, we have also tested printing systems from other suppliers, but we have always returned to Mimaki. With high fashion as our key market, we need to guarantee our customers the highest levels of quality and, to date, we have never found solutions that beat the quality of this Japanese brand’s technology.”

According to Taccani, the difference lies in the “calligraphy” of Mimaki’s machines, that is the line of the ink on the fabric: “Unlike its competitors, Mimaki has focused on the ‘waveforms’, i.e. the electronics associated with the print heads. This attention paid to the way the ink jet is managed from the print head has allowed Mimaki to achieve unparalleled levels of accuracy, an aspect that has given my company a clear competitive edge.”

Moreover, at Digitak, quality comes before quantity: “We prefer to dedicate an extra day to production to guarantee the customer a final product that fully meets requirements and expectations. Mimaki’s technology not only suits this business model bult on top quality, but it crucially enables it.”

Operational and creative flexibility

Digitak currently prints around 2,000 linear metres of fabric per day. Its portfolio ranges from clothing and scarves, to beach and swimwear, with related personalised accessories, to sportswear, with technical properties such as breathability, comfort, resistance to external agents. The company have even added customised outdoor furniture to their offering of diverse and creative products.
The company’s machines operate continuously, 24/7. During the day, the machines are mainly used to develop and produce samples and colour proofs, while the actual production is carried out at night. “Thanks to our technology, we have developed an extraordinary operational flexibility. The fact that we have so many plotters allows us to work on multiple designs at the same time and to launch projects that are also very different from one another,” explains Taccani. “There are also some other crucial factors that have contributed, and continue to contribute, to increasing our production efficiency. The reliability of Mimaki’s solutions and the remote monitoring option offered is key. Once the standard start-up monitoring has been carried out and the machines are found to be printing correctly, we can let them work overnight without an operator. This is a great benefit for people who, like us, manage such a large and diverse fleet of machines.”

Digitak takes the same approach to customer service. Faced with an increasingly demanding market in terms of creativity, precision and completeness of service, the company wants to guarantee flexibility and customisation. “We decided to set up a department dedicated to the pre-press stage, in charge of preparing and checking the files supplied by customers. Seldom do our teams not need to do some editing of the files supplied, even if it’s only to make small changes that are essential for the print document to be as suitable as possible and to achieve the best final result.”

Technologies of the future

With a view to further enhancing production and customer service, Taccani has chosen to take on a new challenge, switching things up with some of the most recent investments.

While maintaining the focus on dye sublimation printing, Taccani has focused on technological diversification by installing a direct-to-fabric digital printing line. This consists of a Mimaki TX300P-1800B printing system with pigment inks and a TR300-1850C coater from Mimaki’s TR series. “The market continues to evolve and now requires even more flexibility regarding both processes and the fabrics supplied. This means that great opportunities exist for a print shop capable of simultaneously producing the same design – with minimal colour adjustment – on different fabrics, guaranteeing similar and accurate results. And this is precisely the path we are taking,” says Taccani. “Why have we opted for Mimaki again? Well, I had an opportunity to try out their new pigment inks and I immediately realised that they are a generation ahead of the other pigments available on the market. The cyan is very clean, the black is deep and there is a very interesting fullness of colour, suitable not only for furnishings, but also for other applications in the clothing sector.”

With its pigment inks, the new direct-to-fabric printing line allows Digitak to explore other related market segments. Thanks to the innovative automatic belt system, the TX300P-1800B guarantees good productivity and high-quality results. A standard of quality that is also boosted by the TR300-1850C fabric pre-treatment system: “This coater is essential for ensuring the best possible preparation of fabrics for printing. In fact, we are able to treat fabrics to make them suitable for the type of print they are intended for, sanitise them for specific applications and, in some cases, even dye them, with excellent quality.”

According to Taccani, another beneficial factor of direct-to-fabric pigment printing technology is the eco-sustainability of the process and its lower environmental impact. “We are proud to be able to offer our customers excellent printing results using little water and printing in ‘green mode’, with both the technologies we have available. I consider them winning technologies for the future, as both dye sublimation printing and direct-to-fabric printing with pigment inks use little water while mainly requiring the use of energy. Therefore, if you use renewable energy, then you’re done.”

Digitak’s other trump card is the Tiger-1800 installed in 2019. With this industrial printing system, the company aims to increase production volumes while maintaining its high-quality standards and further optimising costs. “We are excited to have these promising technologies available to us in-house. We are currently experimenting with these solutions, testing new opportunities and evaluating which paths to take to stay ahead of the game,” concludes Taccani.

Sustainable solutions that pack a punch  

With over 6,500 visitors and more than 2,000 participants at a total of 720 minutes of live presentation sessions and with many potential new customers in the live info chat, the virtual interpack conference organised by Sappi was a resounding success. Sappi presented its latest developments, future prospects and current range of packaging and speciality papers at the event. In addition to further networking opportunities, the visitors took full advantage of the chance to get in contact with the Sales team.

• For the packaging of the future: sustainable, high-quality paper
• Second-generation barrier papers ensure optimal protection of goods as food packaging
• Providing what the world wants: fully recyclable packaging

Based on the motto ‘Pro Planet: Paper Packaging – welcome to the new pack-age’, the market leader in functional paper packaging presented numerous opportunities at its virtual interpack 2020 conference for its customers to package their food or non-food products in sustainable, premium packaging. In doing so, the company is contributing to the UN’s sustainability objectives. With the Sappi Guard range, Sappi presented barrier papers that render additional special coatings and laminations redundant and can be recycled in the paper stream. Featuring integrated barriers, they ensure that the product quality of foods and other goods is preserved. The second generation of barrier papers, now even more environmentally friendly, was also introduced at the virtual event. Another area of focus of the virtual interpack event was sealable papers, suitable for a wide range of packaging applications in the food and non-food sectors.

Of course, the concept of sustainability was also a key issue at the conference. As a home-compostable paper, Algro Nature meets the current demand for fully recyclable packaging. Sappi thus remains true to its goal of presenting its customers with more and more environmentally friendly solutions for the benefit of people and the environment.

‘We were overwhelmed by the success of our first virtual interpack conference, but we look forward to having direct contact again in spring 2021 in Düsseldorf,’ says Thomas Kratochwill, Vice President Sales & Marketing Packaging and Speciality Papers at Sappi Europe, with regard to the delayed interpack conference.

• Joint proposal of TUD and RWTH Aachen University

On 29 May, the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) decided to fund the Collaborative Research Centre (CRC)/Transregio 280 "Carbon reinforced concrete" at Technische Universität Dresden, short TUD, and RWTH Aachen University with the participation of the Institut für Textiltechnik, short ITA, with 12 million euros over the next four years.

The CRC/Transregio 280 “Design Strategies for Material-Minimised Carbon Reinforced Concrete Structures - Principles of a New Approach to Construction” breaks with the traditional way of designing reinforced concrete plants. The interdependence of reinforcement and matrix is being investigated in depth and a completely new design and construction strategy for building with carbon reinforced concrete is being developed.

Carbon reinforced concrete enables completely new design and construction possibilities in the building industry. The reasons for this are its very high strength and the possibility of a very low concrete overlay of only a few millimetres, as carbon, unlike structural steel, does not rust. However, the successful use of the new material, which was awarded the German Future Prize in 2016, requires completely new design and production strategies, which are being investigated in the CRC/Transregio.

Up to now, textile reinforcements have been coated and cured prior to component manufacture. This process is called offline consolidation. These stiff semi-finished products are not suitable for the production of complex components based on new, digital and continuous manufacturing processes (including 3D concrete printing and concrete extrusion). Therefore, ITA is investigating in the sub-project B02 of the CRC/Transregio how forming and consolidation steps are shifted in time by prepreg systems into the concreting process and how they can be applied within the new digital continuous manufacturing processes. In addition to established curing mechanisms, such as by heat or UV radiation, new approaches are also being researched. These new approaches include activation via the alkalinity of the concrete, microwaves and induction

The TUD and RWTH Aachen were awarded the grant on the basis of many years of experience in the research field of textile reinforced concrete. The material textile reinforced concrete was developed in two special research areas at both universities from 1999-2011 and was first fundamentally researched.

19 individual institutes are involved in the CRC/Transregio 280. The spokesman of the TUD is Professor Dr Manfred Curbach, the spokesman of the RWTH is Professor Dr Josef Hegger.

• Launched by SCOTT Sports Racing Team with Sitip, Rosti and ROICA™ by Asahi Kasei

The collection was designed starting from the needs of the athletes with the aim to offer them the best solution in terms of style and ergonomics, high performance, easy maintenance and perfect fit being also sustainable.

Ispo 2020 saw the celebration of the partnership started last year between Scott Racing Team, Rosti, Sitip and ROICA™ by Asahi Kasei for the supply of the team riders’ uniforms. Rosti worked on style and packaging, Sitip on technical fabrics ‘BE-HOT - Heat Generating fabrics’, while ROICA™ provided its premium stretch ingredient. The collaboration carries an interesting news: uniforms are not just highly performing but also, and above all, sustainable.

Sitip created the Native fabric entirely made with recycled yarns and featuring the premium high performing  ROICA™ EF elastomer. The yarn is certified GRS - Global Recycled Standard certification (and also provides special dyeability) with Rosti’s design and high care garment manufacturing.

The main rider of Scott Racing Team Italy, the young and award-winning champion Juri Ragnoli, the “end user” of the uniforms, explaines the requirements that garments should possess in order to meet the sporting challenges that await athletes: breathability, comfort on the skin, performance, durability of the shape and maintenance of the characteristics throughout the course of use of the garment. When asked about the arrival of a new sustainable uniform, the champion said that “it’s right and important to take this direction, which perfectly meets the team’s values, as love for nature and respect for the environment. It will be nice to wear something that follows exactly what you believe in”.

However, other countries – including Bangladesh – are several weeks behind Europe but are expected to follow the same pattern in terms of cases and deaths.

Denim Expert Limited Managing Director, Mostafiz Uddin, has reached out to the global community including brands & retailers, governments, embassies, donors, development agencies, global apparel associations and bodies in these unprecedented times.

Long-term project business in China remains stable 

Oerlikon has received new large orders for manmade fibers production solutions from three of the world’s leading manmade fibers manufacturers. All three companies are based in China and have been key customers of Oerlikon for many years. The orders are for Oerlikon Barmag’s world-leading filament-spinning technology for the highly efficient production of polyester fibers. The three projects have a total value of more than CHF 600 million (EUR 565 million). A very small proportion of these projects will be recognized in Oerlikon Group’s order intake in 2020, and the majority will be accounted for in 2021 and 2022. On-site delivery and installation of these systems are planned for the period from 2021 to early 2023.

The systems business in China remains largely unchanged despite the short-term interruption caused by the coronavirus epidemic following the Chinese New Year celebrations. Long-term project planning for major customers in the manmade fibers industry has resulted in new major orders being placed with Oerlikon Barmag. One of the three new orders, valued at more than CHF300million (EUR282million), is the largest order ever received by Oerlikon Barmag, based in Remscheid, Germany.

The comprehensive manmade fibers technology solutions by Oerlikon are used along the entire value chain in polyester yarn manufacturing and contain cutting-edge automation and digitalization technologies. Oerlikon’s innovative technologies will enable the three Chinese companies to increase their production capacities for polyester yarn and to remain competitive. Oerlikon Barmag will provide the entire system for WINGS POY and WINGS FDY, as well as the texturing machines from the eFK product family in phases over a period of slightly over two years.
