• Clean Technology. Smart Factory.

Remscheid – Oerlikon invites all visitors to this year's ITMA in Barcelona on a journey into the future of manmade fiber production. From 20 to 26 June 2019, the world market leader will show all its guests its vision of a sustainable and automated manmade fiber production in a virtual 4D showroom at its 1,000 m² stand in Hall 7, A101: "Clean Technology. Smart Factory." is the motto of the future. And this is only a stone's throw away from reality at the stand. Because today Oerlikon is presenting four world premieres for efficient machine and plant concepts in a new, innovative industrial design. Together with numerous other innovations, all this forms the new DNA of the Oerlikon Manmade Fibers segment.

The challenges for the manmade fiber industry are manifold and Oerlikon shows its customers solutions:

1. Choosing the right business model
Price pressure on fiber and yarn manufacturers is growing due to global market consolidation. Here it is important to position oneself correctly. Are you producing polyester, nylon or polypropylene for the niche market and skimming off good margins with innovative products and ingenious material properties, or are you looking for business success through economies of scale in the volume market such as the constantly growing apparel sector? Oerlikon has the right answers for both business models. And the most important thing: the market leader supplies all solutions from a single source. See for yourself at the world premieres of the machine and system concepts of WINGS FDY PA6, BCF S8 Tricolor and the revolutionary eAFK Evo texturing machine.

2. Finding alternatives for good personnel
Finding good operators in the manmade fiber industry is becoming increasingly difficult, even in emerging industrial nations such as China, India and Turkey. The solution is obvious. What, for example, the automotive industry achieved years ago with the 3rd Industrial Revolution is now also taking its course in the textile industry. And at the same time it is even shifting up a gear. In the next step, automation in combination with digitization will lead to new, sustainable production. Oerlikon will be showing how automation and digitization interact at ITMA. Self-learning machines and systems, artificial intelligence (AI), remote services and edge computing are just a few of the key words in the digital half of the new Oerlikon Manmade Fibers DNA.

3. Guarantee quality and traceability
The qualities of the fibers and yarns must meet the highest demands and their production must be traceable throughout the textile value chain. This no longer only plays an important role in the automotive industry, where safety is of paramount importance. Other branches of industry that use fibers, yarns and nonwovens also want to know where the raw materials they produce for consumer articles come from. Legal regulations are demanding this more and more frequently. Oerlikon offers optimal solutions with its DIN ISO certified manufacturing processes. More than half of the world's manmade fiber producers are convinced every day that the qualities produced on Oerlikon Barmag, Oerlikon Neumag and Oerlikon Nonwoven equipment are right – and all visitors to ITMA can do the same on site.

4. Efficient and sustainable production
In the future, the materials produced from manmade fibers must become part of a further improved global recycling economy. The recycling of polyester – with over 80% market share the most frequently used manmade fiber in the world – has not only been on the agenda since today. Oerlikon already has solutions at hand: from PET bottles to fibers and filaments, to textiles and carpets. ITMA is the next step. With the VacuFil® Oerlikon in cooperation with the subsidiary company BBEngineering presents the world premiere No. 4 – a recycling solution within a running polyester production with a waste-free approach.

Vision becomes reality
The Oerlikon Manmade Fibers segment thus demonstrates what the ITMA in Barcelona promises as the world's leading trade fair for textile machinery and plant construction: "Innovating the world of textiles – sourcing for a sustainable future". In Hall 7, A101, this is already reality.

Revolutionizing textile finishing by enhancing sustainability and total process control

Baldwin Technology Company Inc., a member of TMAS, the Swedish textile machinery association, is pleased to announce the launch of the TexCoat G4 at the ITMA trade show in Barcelona from June 20-26, 2019. The TexCoat G4 is the next generation of the company’s revolutionary non-contact precision application system for fabric finishing.

The system enables a continuously high quality and productive textile finishing process with zero chemistry waste and drastically reduced water and energy consumption. TexCoat G4 will be demonstrated by Baldwin in Hall H2, stand A204.

“We are immensely proud to launch the TexCoat G4 at ITMA 2019,” said Eric Norling, Vice President Precision Application Segment, Baldwin Technology. “This is an opportunity to experience an innovation that drastically improves both the process and product quality, while saving time, valuable resources and contributing to a sustainable future.”

The non-contact spray technology brings numerous advantages compared to conventional methods of applying finishing chemistry. The chemistry is uniformly distributed across the textile surface and is applied only where it is required – on one or both sides of the fabric. This is highly beneficial e.g. when applying water repellants on laminated fabrics, as it eliminates the problem of chemistry affecting the quality of the adhesion layer. Furthermore, the non-contact technology eliminates chemistry dilution in wet-on-wet processes, allowing full control of maintaining consistent chemistry coverage rates. Additionally, with no bath contamination during the finishing process, there is zero downtime during colour or fabric changeovers.

The Mechanical Engineering Industry Association (VDMA) has awarded two prizes to graduates of the Institut für Textiltechnik (ITA) of RWTH Aachen University - the dissertation prize and the creativity prize of the Walter Reiners Foundation of German Textile Machinery 2018. ITA alumnus Dr Benjamin Weise was awarded the dissertation prize for the development of novel fibres for textile charge storage devices. For their work on a guide to 4D product design, Jan Merlin Abram and Aalon Tal (both ITA students) were honoured with the creativity prize. The dissertation prize is endowed with €5,000 whilst the creativity prize contains a one-year scholarship of €250 per month. Peter D. Dornier, President of the Walter Reiners Foundation and Chairman of the Management Board of Lindauer DORNIER, presented the awards on the 18 September 2018 at the 18th Textile Machinery Forum in the Digital Capability Center in Aachen, Germany.

Graphene revolutionizes all-in-one - supercaps, reduction of terahertz radiation and antistatics

In his dissertation "Development of graphene-modified multifilament yarns for the production of textile charge storage devices", laureate Dr Benjamin Weise developed novel fibres made of polyamide and graphene and further processed them into textile surfaces. The newly developed polyamide graphene fibres are featuring a multitude of advantages:

• Due to their high performance in the charge storage area, they are predestined for use in double-layer capacitors, so-called super capacitors, or supercaps in short. Compared to lithium-ion batteries, supercaps offer significantly higher power density and a longer lifetime as no chemical reactions are taking place. towing to the graphene platelets in the filaments, it is now possible for the first time to integrate a charge storage device directly into a textile without having to sew in a rechargeable battery. This new fibre is therefore suitable for prospective use in smart textiles, for instance in a textile defibrillator.
• The new graphene-modified polyamide fibres can attenuate inident terahertz radiation up to 25 % of their original intensity. Terahertz radiation, for example, offers transmission rates of 100 Mbit/sec and is therefore of high interest for high-performance wireless communication. However, the radiation could damage sensible electronics as in aircrafts if this technology will be used widespread. Consequently, the shielding of the radiation is of high importance, e.g. in the form of fibre composite components in the aircraft, which protect the on-board electronics.
• As the fibres are showcasing a dissipative electrical conductivity, personal protective equipment is another prospective field of application.  

The development of a pilot process for graphene-modified fibres and the production of textile demonstrators are novel and disruptive attainments of Dr Weise’s PhD thesis and the reason for the award ceremony to him. Due to its outstanding properties, the European Union is funding research on graphene within the frame of the "Graphene Flagship" with an overall budget of one billion Euro (source: http://graphene-flagship.eu/project/Pages/About-Graphene-Flagship.aspx).

Modular product design of 4D products is now possible in simplified form

How can three-dimensional products change their shape over time and thus become "four-dimensional"? The students Jan Merlin Abram and Aalon Tal provide answers to this question in their project work "Leitfaden zur Auslegung hybrider morphender Textilien am Beispiel eines Scharniers" (Guidelines for the Design of Hybrid Morphing Textiles Using the Example of a Hinge), for which they were awarded the creativity prize. In their work, the students offer a guideline for the development of a four-dimensional textile from the idea to the demonstrator. Four-dimensional textiles, for example, consist of a hybrid material of elastic textile on which three-dimensional structures are printed. The fourth dimension describes the change in shape and/or a property over a defined period of time (= morphing).  This change is caused by external influences such as light and heat.

Every year, the Foundation of the German Textile Machinery awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the smartest student research project. Further prizes were awarded to Eric Otto, ITM Dresden, and Susanne Fischer, Reutlingen University.
