From the Sector

During an expansive, three-day Electronics For Imaging, Inc. open house this month at the company’s EFI™ Reggiani industrial textile printer facility, textile and apparel manufacturers witnessed first-hand the market-leading innovations that provide users with new opportunities. The December open house, which drew more than 70 attendees from over 23 different European, South American, and Middle Eastern countries, featured informative sessions with product experts on a diverse range of topics, covering new and trending market applications for textile manufacturers.

Attendees witnessed live demonstrations of eight advanced digital printers during the open house, including the new EFI Reggiani HYPER, EFI Reggiani TERRA Silver scanning/multi-pass printer, and EFI Reggiani BLAZE as well as the EFI Reggiani BOLT – the award-winning single-pass offering that is the one of the fastest digital textile printers.

EFI Reggiani HYPER – a fast scanning digital printer
The new EFI Reggiani HYPER is a scanning printer available in 1.8-metre, 2.4-metre or 3.4-metre widths. The Reggiani HYPER model targets the industrial high-speed segment of the multi-pass textile printing sector.

With an up to eight-colour configuration, it prints at speeds up to 13 linear metres per minute in two-pass production mode. The new printer is suitable for high-quality production on knitted or woven fabrics and is designed with smart technology that enables it to be integrated into Industry 4.0 projects.

Sustainable direct-to-textile printing with the EFI Reggiani TERRA Silver
The new-version TERRA Silver printer is part of EFI’s complete TERRA line-up of pigment ink printer solutions. It allows print service providers to enter the world of industrial textile with a short, smart and green production process.
The printer also features:

• A new recirculating ink system for superior reliability and minimum maintenance
• Several printing modes to ensure maximum flexibility in terms of design capability
• New, real-time image processing that eliminates time spent in image pre-calculations
• A user friendly, intuitive interface
• A more-efficient polymerisation process that takes place as printed textile goes through the printer’s on-board dryer.

EFI Reggiani BLAZE, an ideal entry solution for industrial textile printing
The EFI Reggiani BLAZE printer is designed to give textile companies the opportunity to enter the digital textile printing market with a compact solution. The new, 1.8-metre-wide printer offers an innovative, low-maintenance, continuous recirculation ink system equipped with a level sensor and degassing as well as a print head crash protective system for longer printhead life and superior uptime.

The upgraded EFI Reggiani BOLT – one of the fastest digital textile printers
In 2021, the EFI Reggiani BOLT received a combination of hardware and software enhancements that minimise artifacts, compensating for missing nozzles that may occur over time and enhancing uniformity to deliver smoother solid colours. The upgrade also delivers improved quality and smoother gradients, plus it enables faster printhead replacement and drastically increases file processing speed by up to 200% for large, complex files.

On 27 November 2021, the Scientific Award for International Sustainable Aviation and Energy Society (SARES Award) was awarded to Professor Dr Thomas Gries from the Institut für Textiltechnik of RWTH Aachen University. The award ceremony took place during the closing ceremony of the International Symposium on Sustainable Aviation (ISSA) in a hybrid format online and simultaneously at Kasetsart University, Bangkok, Thailand.
 
With the award, the committee recognised the ongoing contribution of Pro-fessor Gries and the Institut für Textiltechnik to the digitisation and bio-transformation of the textile sector, as well as the Institute as a place of innovation for sustainable aviation.

Examples of this include the development of 3D braided ceramic matrix composite components for aircraft engines, which were researched together with partners in a Horizon 2020 project (EU project AllOxITD). The ongoing Chrysomallos research project as another example, funded under the national aeronautics research programme in Germany, aims to develop a completely new and sustainable high-performance insulator for aircraft cabins based on aerogels. These have a significantly lower weight than the glass fibre mats used up to now, while providing the same insulation performance, and solve the problem of the previously high manufacturing costs of aerogels. The aim of the project is to develop an insulation material with reduced density (reduction of more than 20 percent). To this end, a new type of insulation material based on aerogel is to be developed. The basis is an aerogel fleece (0.06 W/mK at 28 kg/m³), which has already been developed as part of a dissertation at the Institut für Textiltechnik of RWTH Aachen University (Mroszczok, J.: 2019).

The aviation industry is one of the fastest growing industries in the world. Due to this fact and its importance for society and the global economy, it needs to make special efforts towards sustainability. The ISSA, an international multi-disciplinary symposium, aims to address current issues in aviation such as improving aircraft fuel efficiency, promoting the use of biofuels, minimising environmental impact, mitigating greenhouse gas emissions and reducing engine and aircraft noise. ^

Through the award, SARES honours scientists and researchers whose work on sustainable aviation issues has made an important contribution at the international level. The selection is based on the scientific publications of the applicant or nominee, the h-index, i.e. the key figure for the worldwide perception of a scientist in professional circles, the project topics and the project results.

imm cologne will not take place on the planned dates in January 2022 in Cologne. The executive board of Koelnmesse reached this decision in close consultation with the Association of the German Furniture Industry (VDM) and in agreement with other well-known industry representatives at the international level. "This step is restricted exclusively to imm cologne and its specific requirements for trade fair operations. We are principally planning, as before, to carry out our spring events in 2022. The political guidelines allow for this, and, following the excellent and safe course of the past autumn trade fairs, this must remain our mission in the interests of the participating industries“, says COO Oliver Frese.

The VDM, as the industry sponsor of the event, and against the background of the current pandemic situation, sees the economic success of the event and thus the successful restart of imm cologne in January as extremely endangered. "Following consultation with numerous exhibitors, industry representatives and trading partners, there is either no question of participation on the part of German exhibitors or exhibitors from the German-speaking region, or this is very much in doubt", according to Jan Kurth, CEO of the VDM.  Similar feedback also came from many European countries.

"The current special basic conditions in the interior design industry make the practicability of imm cologne almost impossible", according to Oliver Frese. "We didn't make this very bitter decision easy for ourselves, but consider it to be our obligation to take this step now in close consultation with the industry. In this way we provide clarity and planning security in the interests of our exhibitors. In our shared perspective, an imm cologne with its claim as a leading trade fair for the interior design industry is not realisable in the current situation", the COO continues. "We are currently working actively on options for also still being able to offer exhibitors of imm cologne an attractive trade fair presence at the international level. Here, both spoga+gafa and ORGATEC present excellent alternatives in the interior design portfolio of Koelnmesse".

The cancellation is restricted to imm cologne and expressly does not include other B2B events planned for spring 2022 in Cologne. In autumn, the Cologne art fairs and the nutrition fair Anuga, among others, demonstrated that trade fairs are also once again possible at the international level and can be carried out safely for everyone. It is currently quite clear how differently individual industries are reacting to the present situation. "We have determined a heterogeneous estimation among the exhibiting companies in the face of the enduring pandemic situation in Germany", according to Oliver Frese, COO of Koelnmesse. The assessments vary in degree specific to different industries, "sometimes with a greater impact on the respective trade fair and sometimes hardly palpable", the COO continues. "In the interests of cooperation in a spirit of trust, we are of course communicating closely with our industries and customers, in order to be able to reach just these kinds of industry-specific decisions," according to Frese.

The hygiene and safety concept of Koelnmesse, which remains entirely in keeping with the decisions of the Minister-President Conference and the Corona Protection Ordinance of NRW, stands for safe processes.

A positive picture was still taking shape for imm cologne as a whole with the end of the term for cancellation without penalties in mid-October: with 600 exhibitors from more than 50 countries, the event would still have been the largest and most relevant forum for the interiors industry, hosted in Europe’s biggest furniture market, even in this smaller form in terms of numbers.

The professional exchange and the networking between internationally active companies and highly qualified trade visitors provide the basis at every imm cologne for future-oriented innovations and the development of new business models. In this way, imm cologne ensures important business impulses for the industry. Koelnmesse, together with the VDM and the exhibiting industry, will therefore do everything possible to get a powerful and innovative imm cologne 2023 on its feet.        

Sateri’s Lyocell facility in Rizhao, Shandong Province, has been awarded the Sustainable Textile Production (STeP) certification for responsible production, making it the first Lyocell producer in China to be certified to the rigorous standards set by independent Swiss-based certification organisation OEKO-TEX®. Sateri’s Lyocell facility has also obtained the highest ranking of level three in the certification assessment scoring for exemplary implementation of best manufacturing practices.

Together with its earlier achievement of the STANDARD 100 by OEKO-TEX® certification that confirms its Lyocell fibre is free from any harmful substances and complies with European standards, Sateri’s lyocell products are qualified to carry the MADE IN GREEN by OEKO-TEX® product label. This label not only attests to Sateri’s Lyocell fibre as safe and manufactured in environmentally-friendly, socially responsible and safe facility, but also the Group’s commitment to higher levels of transparency and accountability through the product traceability feature of the label.

The STeP by OEKO-TEX® certification comprises three levels describing the extent to which a company has achieved sustainable production and working conditions of factories in the textile industry. The areas of assessment include chemicals management, environmental performance, environmental management, social responsibility, quality management, as well as occupational health and safety.

Sateri’s Lyocell fiber factory in Rizhao commenced operation in May 2020, with an annual output of 20,000 tonnes of Lyocell fiber. The same site houses a 5,000 tonne Lyocell pilot production line dedicated for the development of Lyocell application technology. In March 2021, the Group announced plans to expand its Lyocell annual production capacity in China up to 500,000 tonnes by 2025.

A natural and biodegradable fibre, Sateri’s Lyocell is made from wood pulp sourced from certified and sustainable plantations. It is manufactured using closed-loop technology, requiring minimal chemical input during the production process, and utilising an organic solvent that can be almost fully (99.7%) recovered and recycled.

Sateri’s Lyocell is used to produce high quality textiles and personal hygiene materials. Using a unique high technology manufacturing process, it has outstanding dry and wet strength, high uniformity and consistency, and superior quality. It blends well with various textile fibres to create different fabric styles and characteristics for wide downstream applications.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

After its launch on 20 September 2020, the RCI is proud to celebrate its first anniversary this fall. The balance sheet of the first year is impressive: starting from 11 founding members, that number increased to 30 member companies within 12 months. Numerous webinars, press releases, background information, a glossary and a comic allowed to convey the “Renewable Carbon” concept to the public. The RCI is actively working on labelling and policy analysis, and more activities will follow in the next year.

Key for this success: the topic of renewable carbon in chemicals and materials is increasingly becoming a focus of politics and industry. Larger companies will have to report their GHG emissions and also the footprint of their products as part of legislative changes surrounding the European Green Deal. In this context, indirect emissions and the carbon sources of materials will play a much more crucial role. The RCI is actively working on solutions for companies to shift from fossil to renewable carbon, which consists of the use of bio-based feedstock, CO2-based resources and recycling. In the future, reporting on GHG emissions will also include Scope 3 emissions, which are all indirect emissions that occur along the company’s value and supply chain and where the used raw materials account for a large proportion of the footprint. Here is where the carbon source of chemicals and plastics comes into play as an important contributor to the carbon footprint. Without a shift from fossil to renewable carbon feedstocks (combining bio-based, CO2-based and recycled), a sustainable future and the Paris climate targets will be almost impossible to master.

To discuss, promote and realise the shift, 30 innovative companies have already joined forces to support the transition to renewable carbon, considering both technological and economical approaches – and helping to shape the political framework accordingly.

For the second year, RCI plans to focus on a comprehensive understanding of the expected political framework conditions in Europe and across the globe, since they will determine the future of chemistry and materials more than ever. Building on this knowledge, the topic of renewable carbon could then to be systematically integrated into new political directives, which has so far not been effectively managed.

In reality, the political focus lies on the strategy of decarbonising the energy sector, a very central and Herculean task. However, it cannot be applied to the chemical and material world because carbon is usually the central building block that cannot be dispensed with. On the contrary, the demand for carbon in the chemical and materials sectors is expected to more than double by 2050. In order to meet this demand in a sustainable manner, we must move towards quitting fossil carbon. For the first time in industrial history, it is possible to decouple chemistry and materials from petrochemicals and completely cover the demand through the utilisation of biomass, CO2 and recycling.

10 years after the installation of the photovoltaic plant in the production units in the Biellese region, the Marchi & Fildi Group takes stock of the operation and publishes the data on energy produced, consumed, and fed back into the grid.

The photovoltaic plant owned by the Group is made up of 11,385 modules divided between the three facilities in Biella (Production), Cerrione (Dyeing mill) and Verrone (Logistics), which in total cover a surface of 16,515 sq.m.

The balance to be drawn from these 10 years is a positive one: in total 22,974,828 kWh have been produced, of which 7,292,027 kWh have been used in company activities, with a saving in energy costs of approximately €1m over 10 years.  

The energy kWh produced and not used by the company was fed back into the grid and corresponds to the average annual consumption of around 4630 families.*

The Marchi & Fildi Group has always been committed to rationalising electric energy consumption with the aim of contributing towards an eco-sustainable development without compromising the rate of production and the ability to grow. In addition to producing its own electric energy, over the years, the company has also achieved an increasing number of Energy Efficiency Titles (TEE), otherwise known as white certificates. In 2021, 138 TEEs have been awarded as a result of such interventions as the introduction of LED lighting and the optimisation of the production processes which, while still as efficient as before, permit the company to reduce the electric energy consumption of the machinery.

*In the meter class for the range of 3kW to 4.5 kW, the average consumption for residential properties is the equivalent of 3,382 kWh (source: Arera Relazione annual state of services for the year 2020). The calculations are the results of an internal study conducted by the Marchi & Fildi Group.

Knopf’s Sohn, a contract finisher of technical textiles, has installed a fully automated Montex stenter at its plant in Helmbrechts, Germany.
Knopf’s Sohn is processing technical textiles for the automotive, aerospace, home furnishings and workwear markets, based on wool, cellulose, polyamide and polyester fabrics, along with elastane blends, in weights of 80-800gsm.

The Montex machinery range is constantly being upgraded to meet evolving customer needs for greater automation, ease of operation and energy optimisation. The latest ten chamber line at Knopf’s Sohn, with a working width of up to 2.0 metres, was engineered to specific requirements in order to accelerate the company’s move to fully automatic control of its production, and high scaffolding was required for its installation.

The line benefits from two integrated ECO Booster modules to provide high energy savings. These compact, air-to-air heat exchangers, installed within the roof structure of the line, exploit energy from the exhaust gas to preheat up to 60% of the incoming fresh air entering the stenter.

The use of a single ECO Booster unit has been calculated to save up to 35% in energy costs, based on fixation processes. Fully automatic operation, set at the Monforts Qualitex control unit, ensures there is no additional burden on the machine operator.

The line is powered by Exxotherm indirect heating, which practically eliminates the yellowing which can be experienced during the treatment of certain polyamide and elastane-based fabrics, and is also equipped with a Conticlean circulating air filter system for constant high drying capacity.

Software
The latest Qualitex visualisation software offers operators reliability and easy control with its full HD multi-touch monitor and slider function, dashboard function with individual adaptation to operating states and faster access to comprehensive recipe data management.

With the Monformatic control system, the exact maintenance of the dwell time in combined treatment processes (drying and heat-setting) can be monitored. When the heat-setting point is reached, the fan speed is automatically adjusted, keeping energy consumption fully under control.

• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer enterprise development teams and individually for the respective projects." This is how novel and unique lightweight components made of high-performance textiles are created for visionary projects.
