Oerlikon Polymer Processing Solutions at ITMA Asia + CITME 2022
'At Oerlikon, we contribute with our innovative technologies for resource-saving use in almost all manmade fiber spinning mills in the world. Our promise for the future is to continue to expand the zero-waste production approach and thus take care of achieving our customers' and our own sustainability goals', says
Circular Economy and recycling Enabling customers to achieve more with less
Textiles are becoming an increasingly big polluter. To tackle the growing mountains of used clothing, it is above all European politicians who are developing a comprehensive strategy for a regulating circular economy. And the textiles industry is also making its mark with innovative technologies for recycling manmade fibers. However, there is still a long way to go before we have a sustainable textile world.
According to the
With this market development in mind,
In terms of sustainability, however,
In addition to regulatory initiatives, technical innovation is required to connect the beginning and the end of the linear textiles industry and to close the loop. One decisive circular technology here is fiber-to-fiber recycling. Only a few years ago, this process was used to recycle around just one percent of used clothing worldwide into fibers for new apparel. McKinsey market researchers are now talking about 18 to 26 percent being recycled by 2030 - if the full technical recycling potential is utilized and more textiles are collected. For this, manual processes will have to be automated, clothing waste qualitatively sorted, buttons and zips removed, and fiber compositions unambiguously identified - and all less expensively. Separating mixed fibers still represents an obstacle as well. Finally, the recycled materials must be suitable for the spinning process, provide a usable yarn quality and be able to be further processed, i.e., dyed. Despite these challenges, there are promising solutions on the horizon, even though some processes are not yet ready for commercial exploitation.
Oerlikon Barmag is offering technological solutions for rPET that enable customers to save million tons of CO2 per year. In 2022, Oerlikon Barmag introduced, a homogenizer recycling line specifically for customers in
Another rPET solution is the VacuFil system from the Oerlikon Barmag joint venture, BB Engineering. VacuFil is a unique and innovative PET recycling line, uniting gentle large-scale filtration and targeted intrinsic viscoscity (IV) regulation for consistently outstanding rPET melt quality. In 2022, BB Engineering launched a patented key component of the VacuFil system, the Visco+ filter as a separate and easily integrable upgrade component that enables precise IV setting and pure melt with the help of vacuum. IV is the central quality characteristic in PET recycling and rPET processing. It determines the melting performance in the production process and the properties of the end products and is thus essential in the recycling process. The Visco+ process is reliable, verifiable and 50% faster than conventional liquid-state polycondensation systems.
Energy Efficiency EvoSteam process revolutionizes polyester staple fiber production
There is a huge demand for textile fibers: population growth of around 3% per annum, fast fashion and many other factors are fueling this demand. According to international studies, global demand for staple fibers made from polyester will total 20 million tons in 2025 - this is approx. 33% more than the production volume recorded in 2013. In view of noticeable climate change and its impact on people and the economy, resource- and environment-friendly manufacturing methods are absolutely crucial for the future. High production costs are currently eating into the margins of fiber producers. Noteworthy here are above all massively increased energy and polymer prices, but water is also an important resource today - very frequently scarce and consequently expensive. At this year's ITMA Asia + CITME 2022 in
New Materials
Looking back at the regulations of the
'In the polymer processing industry, we have to come to a sustainable, closed circular economy for packaging materials and textiles, for example, while simultaneously intensively expanding the recycling of the materials used. Here, new materials also offer opportunities - opportunities that we as a machine manufacturer and plant engineering company will exploit. However, compared to non-biodegradable, petrochemical-based polymers such as PE, PET and PP, the prices for bio-based polymers like PA 5.6. and biodegradable polymers like PLA, PBAT and

Digitalization and Traceability
With its sustainable and closed loop-compatible textiles strategy, the EU plans to become a pioneer for the global circular economy as well. By 2030, textile products marketed within the EU are to become more durable and recyclable, predominantly comprise recycled fibers, contain no hazardous substances and be manufactured in compliance with social rights and in a manner that protects the environmental. This also includes the introduction of a digital product passport and the amendment of the European Textile Labeling Act: To implement the closed-loop principle and other important environmental requirements, players along the value chain must also fulfill new information obligations about the composition of textiles. At the show,
Looking into the future with the Oerlikon Barmag Digital Twin
The term 'digital twin' was coined in 2014 by
Interactive and customized, modular and flexible in terms of time - all features of a modern training concept. Adapted to the needs and general conditions of the respective student, training sessions should be independent of time and place and the contents should be tailored. This concept is being implemented within the

Oerlikon Barmag Wiping Robot
Regular wiping of the spin packs is important for process stability and yarn quality. Automating the process with Oerlikon Barmag's wiping robots, which can be retrofitted to numerous spinning plants, delivers considerable benefits, as it reduces the yarn break rate by up to 30%, improves process stability and reduces downtime. In addition, wiping robots help to indirectly reduce waste as a result of a 90% decrease in the use of silicone oil spray cans and a 15% to 20% decrease in total silicone oil consumption.
Oerlikon Nonwoven HycuTEC
Oerlikon Nonwoven's HycuTEC inline charging technology is used to create high-end charged meltblown filtration media. Introduced in March, it went on to win the 2022 FILTREX Innovation Award. One of the reasons HycuTEC won the award was that the meltblown media treated with the technology requires 40% less polymer (fabric weight) to achieve the same filter efficiency than the nonwoven material that was not treated. In other words, filter specification is easier to achieve while reducing waste in production. Compared with other hydro-charging concepts, the unit significantly reduces water and energy consumption due to the elimination of an additional drying process and the lower pressure drop in the filter material. HycuTEC is the first industrially manufactured hydro-charging solution that can be easily retrofitted to existing systems as a plug-and-produce component.
