From the Sector

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

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

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

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

Technology transfer that is creating waves

For more than a decade now, the Manmade Fibers segment of the Swiss Oerlikon Group has been hosting a comprehensive technology symposium at the beginning of each year in the Indian region around Silvassa/Daman. Numerous Indian manmade fiber producers have settled in this area, around a four-hour drive north of Mumbai. Fed from Oerlikon polycondensation and extrusion systems, these companies manufacture polyester, nylon and polypropylene on large-scale installations with Oerlikon Barmag WINGS POY, WINGS FDY, IDY and DTY product lines and using Oerlikon Neumag’s staple fiber and BCF technologies. Reason enough for the Manmade Fibers segment’s experts to regularly provide their clientèle with detailed specialist presentations in India on the latest developments of the product and service portfolio.

And this was once again the case at the event held at the beginning of 2020, where around 450 managers and employees from local businesses took the opportunity to exchange ideas and information. For the third time in succession, Oerlikon also entered into dialog with the next generation of managers at major Indian polyester and nylon manufacturers in a separate event hosted in Mumbai beforehand. The technology symposium was again held – for the very first time – just a few days later and in a slightly modified form at a second venue: in Kolkata in West Bengal, a potential second future key location for manufacturing manmade fibers in India according to plans revealed by the Indian government. Here, the discussions held by the Oerlikon experts focused above all on the transfer of technologies for manufacturing polyester, nylon and polypropylene. Oerlikon is able to offer the entire process chain – from the melt to the textured yarn or the fibers and including the necessary semi- and fullyautomated logistics process – from a single source. This is of interest above all for potential new customers and investors in West Bengal and neighboring Bangladesh, as some do not have decades of expertise in manufacturing manmade fibers, as is the case for most companies in the region around Silvassa/Daman.

• 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.

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.

Wilmington, MA – March 1, 2018 - Koch Membrane Systems, Inc. (KMS), a global leader in membrane filtration technologies, announced today that it has provided PURON® Membrane Bio-Reactor (MBR) modules as part of a system upgrade to the wastewater treatment facility of KPR Mill Limited. KPR Mill is one of the largest apparel manufacturing companies in India. KPR Mill decided to upgrade their wastewater treatment facility from an old conventional plant to an advanced MBR technology due to its environmental commitment to ensure zero liquid discharge (ZLD) by recycling 100% of their wastewater. Among the key reasons for selecting the PURON® MBR modules are its unique design, including single header and central aeration, reliable and consistent operation, and strong after-market support from KMS.
 
KPR Mill has been using a conventional Effluent Treatment Plant (ETP).  Their old technology involved high chemicals consumption which required high maintenance levels, resulting in frequent production shut downs due to ETP failures.  The new MBR plant is designed to handle 3000 m³/day of textile effluent, utilizing two MBR trains. Initial results show that KPR Mill has reduced chemical costs and eliminated downtime, maximizing textile production. In addition to savings in operational cost and production optimization, KPR strives for an eco-friendly textile processing system. KPR’s selection of PURON® membranes help them achieve their goals of environmental sustainability.
 
“The membrane bioreactor technology from KMS operates very reliably and has resulted in a significant reduction of chemical, operating and maintenance costs of about 10%,” said Mr. C.R. Ananda Krishnan, executive director of KPR Mill Limited. “And as we are a trend setter in using eco-friendly advanced technologies, we were happy to have PURON® MBR as a technology partner who fits our needs and our vision.”
 
“KMS has developed advanced membrane solutions for the textile industry,” said Mr. Manny Singh, President of KMS. “Our products and services help the industry treat wastewater to meet strict discharge and reuse targets, and create value through various chemical recovery processes.”
