Environmental news and technical  innovation in the nonwovens sector

NEUMÜNSTER - At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial nonwovens.

Between June 21 and 24, the discussions in Hall 12.0, Stand C60 will also concentrate on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. “With our unique, patented Single Filament Layer Technology, we offer a sophisticated and simultaneously gentle high-tenacity (HT) yarn process for manufacturing seatbelts, airbags and other applications made from industrial yarn,” explained Dr. Roy Dolmans, Technology Manager IDY and R&D Filament Processing.

With its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is described as a future-proof, sustainable technology.

Also on show will be the company's offering of low stretch, ultra-high tenacity, high rigidity industrial yarns that are designed to offer outstanding properties for the demanding tasks carried out by geotextiles; for example, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fibre technology centers. As of now, these state-of-the-art staple fibre technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. “We are not only able to run all standard products available on the market at our Technology Center, it also offers us the perfect prerequisites for the development of new processes and products," explained Tilman Reutter, Technology Manager - Head of Staple Fiber Process. "Here, the fibre tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products."

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fibre quality and properties and are deployed in all Oerlikon Neumag production systems.
