• Milliken purchases spinning plant from Gildan to strengthen internal yarn production

Milliken & Company, a diversified global manufacturer innovating in the textile, chemical, floor covering and healthcare industries, recently acquired one of the Frontier yarn plants in Mayodan, North Carolina, from Gildan. This plant acquisition expands Milliken’s open-end yarn production for its protective fabrics, workwear, government and defense, industrial, and napery textile business units.

The Frontier Spinning Plant #3, which will be renamed the Two Rivers Plant as a nod to its dedicated team and the community it serves, will become a spinning hub for Milliken. Multiple Milliken textile plants throughout the Southeast will source their yarn needs from the Two Rivers Plant.

“Adding this plant to the Milliken manufacturing footprint helps us meet current production needs and offers additional capacity for future growth,” says Kevin Brown, senior vice president of global operations for Milliken’s Textile Business. “The expansion helps us create a resilient supply chain that offers consistency and surety for both our product lines and customers.”

• Sustainable infrastructure solutions, road safety and health protection

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 textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, 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.

hycuTEC – technological quantum leap for filter media
In the case of 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 also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber 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. Here, the fiber 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 fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

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%.

The Oerlikon Manmade Fibers segment will be presenting itself at the Egy Stitch & Tex 2020 between March 5 and 8, 2020 in Cairo – with a clear focus on the needs of the African market. In Hall 1, Stand B2 The Oerlikon Barmag and Oerlikon Neumag experts will also be showcasing the comprehensive product and service portfolio of the world market leader for manmade fiber systems at the stand of Oerlikon’s representative ATAG Export & Import.

The spotlight of the Oerlikon Manmade Fibers segment’s trade fair attendance will be on two core technologies: the new generation of Oerlikon Barmag eAFK Evo texturing machines is to be unveiled within the African market for the very first time. It promises higher speeds and productivity with consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. In particular, the numerous value-added features include two that convince with cutting-edge technology: the optimized, innovative EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

The second technology focus offers new opportunities for the Egyptian market and the Middle Eastern markets in particular: with Oerlikon Neumag’s BCF S8 monocolor and tricolor system, the segment will be unveiling its new carpet yarn production flagship. Superlative spinning speeds, up to 700 individual filaments, finer titers of up to 2.5 dpf – the performance data and technological finesse of the new system have already made a huge impression at numerous trade fairs and roadshows over the past year. The tricolor’s core component is the new, patent-pending Color Pop Compacting unit (CPC-T) for even more flexible and more even color separation. With the CPC-T, individually-controllable air pressures for each color provide pre-tangling, which accentuates the colors and hence makes more than 200,000 different shades possible. Whereas it has been very difficult to manufacture strongly color-separated or color-accentuated BCF yarns from polyamide 6 to date, this will in future be possible thanks to the CPC-T system. As a result of the new design, the CPC-T is now also suitable for processes with low yarn tensions.
 
Expanded product offering for manufacturing carpet yarns
Know-how covering all relevant technologies deployed in manmade fiber spinning plants enables Oerlikon – as the world’s only manufacturer – to expand its range of products and services for making carpet yarns. The POY- and texturing-based system concept is designed for a carpet and home textiles segment that demands particularly soft and bulky polyester yarns with BCF-like properties. Here, the aim is to produce yarns with titers of max. 1300dtex and typically more than 1,000 filaments, with typical products including, for example, 1300dtex f1152, 660dtex f1152 and 990dtex f768. The machine concept comprises the well-known WINGS HD POY winder, along with the eAFK Big-V texturing machine.
