Recycling rückt in den Fokus

Müllberge, plastikverseuchte Meere, CO2 Footprint – die Notwendigkeit einer nachhaltigeren Lebensweise ist alternativlos. Logisch, dass Recycling Lösungen in der Textilindustrie zunehmend an Bedeutung gewinnen. Aufgegriffen hat das auch der erste virtuelle Global Fiber Congress in Dornbirn mit einer eigens auf das Thema fokussierten Session. Vor rund 400 Teilnehmern referierte auch Markus Reichwein, Leiter Produktmanagement bei Oerlikon Manmade Fibers, zu auf dem Markt verfügbaren Lösungen.

Als einer der einzigen Hersteller bietet das Segment Manmade Fibers des Oerlikon Konzerns die gesamte Kette des mechanischen Recylings von der Aufbereitung des Rezyklats zur Schmelze bis hin zur texturierten Spule. Dabei greift das Unternehmen auf die VacuFil Lösung seines Tochterunternehmens Barmag Brückner Engineering (BBE) zurück, die neben bottle-to-bottle und bottle-to-textile Prozessen auch die Verarbeitung von textilen Abfällen zu Chips beherrscht. Damit wird der Betrieb von Textilproduktionen im Sinne der Zero Waste Philopsophie möglich.

VacuFil sorgt für stabilen Prozess recycelter Qualitätsgarne
Wesentlich für einen stabilen und effizienten Spinnprozess und ausgezeichneter Garnqualität ist die zuverlässige Entfernung von Verunreinigungen. Gleichzeitig sind stabile Betriebsbedingungen mit möglichst minimalen Schwankungen essentiell. Die größte Herausforderung hierbei sind die unterschiedlichen Qualitäten der eingespeisten bottle flakes, da der Extrusionsprozess diese Schwankungen kaum ausgleichen kann. Hier steuert das VacuFil Konzept mit Mischsilos gegen. Damit werden die Unterschiede in der Viskosität der Polymere deutlich reduziert, so dass eine hohe Garn- und Gewebequalität garantiert ist.

Das VacuFil Konzept ist einer POY-Anlage von Oerlikon Barmag vorgeschaltet, die mit der rezyklierten Schmelze gewohnt hochwertiges Filamentgarn produziert. Als Texturierungslösungen bietet Oerlikon Barmag seine modernsten Anlagen der automatischen eAFK-Serie an, darunter auch die neueste Generation der eAFK Evo, die letztes Jahr auf der ITMA Barcelona vorgestellt wurde. Garnhersteller, die weiterhin manuell texturieren möchten, können auf die eFK-Serie zurückgreifen.

Mit VarioFil R+ steht Herstellern kleinerer Chargen zudem eine Kompaktanlage mit integrierter Rezyklataufbereitung zur Verfügung. Die Anlage bietet ein spezielles Extrusionssystem für Bottle-Flake Materialien, die neueste Dosier-und Mischtechnologie für Spinnfärben und eine erweiterte 2-Stufen-Schmelzefiltration. Die vier Spinnpositionen sind jeweils mit einem Oerlikon Barmag 10-end WINGS POY Wickler bestückt.

Ist das mechanische Recycling bereits sehr ausgereift, stellt das chemische Recycling für Mischgewebe die Textilindustrie noch vor große Herausforderungen. An Lösungen und Konzepten, aus diesen Geweben neue Textilien gewinnen zu können, arbeitet das Segment Manmade Fibers des Oerlikon Konzerns.

Oerlikon Manmade Fibers opens new sales and service office in Shanghai, China

  • "Even closer to our customers"

After more than eight years in the Intercontinental Business Center on Yutong Road in Shanghai, China, the Manmade Fibers segment has now opened a new sales and service office in the metropolis of millions near the international airport in Hongqiao and the National Exhibition and Convention Center (NECC).

The Manmade Fibers segment in China now officially operates under the following address:

Oerlikon (China) Technology Co. Ltd.
Shanghai Branch
RM1208-1210, Tower A, The Place,
100 Zunyi Road, Changning District
Shanghai China 200051

The main reason for the change from Yutong Road to the new address on Zunyi Road was the logistical aspects in a city that has had to cope with increasingly heavy traffic in recent years. "Now we are even closer to our customers," explains Wang Jun, Oerlikon China President. The proximity to Hongqiao airport and the Hongqiao railway station with its high-speed trains will provide the sales and service staff with even better infrastructure connections.

Furthermore, the local repositioning also takes into account the changes within the Oerlikon Group. "The divestments made within the Oerlikon Group in recent years have now led to a reorganization here in Shanghai. Today, Oerlikon's business activities in China focus exclusively on the segments Manmade Fibers and Surface Solutions incl. Additive Manufacturing. The time had come to set up the best possible infrastructure for optimum customer service for both business segments," continues Wang Jun. In addition, in the age of digitalization, sales and service employees in China are increasingly able to work from home. All of this has now led to a changed, adapted and, last but not least, cost-optimized reorganization.

Whether commodities or niche products – the new BCF S8 platform technology offers manufacturers of BCF carpet yarns decisive arguments for responding to constantly rising cost pressures and the trend for greater efficiency and quality in fiercely-competitive markets. World record: the system achieves never-seen-before spinning speeds and is able to simultaneously spin up to 700 filaments and produce fine titers of up to 2.5 dpf. This superlative performance is guaranteed by numerous individual innovations in the new platform and, for the first time, also in a new human-machine interface (HMI)-based control system, which opens the door to the digital age of smart carpet yarn manufacturing wide. At the ITMA ASIA 2018, the Oerlikon Manmade Fibers segment had already announced that it would be presenting revolutionary solutions in 2019 – both in hardware and software. And the DOMOTEX marks only the start.

According to manufacturer information, the new BCF S8 is the most efficient Oerlikon Neumag BCF system of all times. “We have succeeded in achieving a new level of greater productivity and even broader product diversity. These allow our clientèle to better cater to changing market requirements and achieve a competitive edge in tough market conditions”, explains Martin Rademacher, Vice President Sales Oerlikon Neumag. As a pre-taste, the machine specialists from Neumünster are serving up performance figures and results from comprehensive trials conducted at their own BCF technology center as well as from two pilot systems which have been tried and tested within the market for months now.

BCF S8 performance in numbers
With up to 700 potential filaments per yarn end, the BCF S8 is raising the benchmark considerably compared to the Oerlikon Neumag S+ BCF system (400 filaments) that has dominated the global market to date. Oerlikon Neumag guarantees fine titers of up to 2.5 dpf. Furthermore, the process speed is higher than ever before – 3,700 m/min (winder speed). This permits throughputs of up to 15 percent greater compared to predecessor technologies. Overall, system efficiency is 99 percent – almost unbeatable. True to the Oerlikon Segments Manmade Fibers segment e-save philosophy, energy savings of up to 5 percent per kilogram of yarn are achievable.

BCF S8 innovations – from straight yarn paths to large cooling drums

This comprehensive progress has been achieved with numerous smart innovations. To this end, one key element above all has been optimized. The yarn path from the spinning system to the new, large cooling drum has now been almost completely straightened. This yarn path, unique to the BCF market to date, ensures that the individual filaments are subjected to minimum friction, hence once again considerably reducing yarn breaks and optimizing the overall production process. Especially noteworthy here are the, for the first time, straight yarn inlet in the texturing head – guaranteeing superior yarn quality.

And the considerably reduced distance between the heating godet duo and the texturing head also has a positive impact on the texturing process. It ensures a more even twist to the yarn and reduces the compressed air consumption. Furthermore, the texturing chambers can be removed individually, which additionally shortens servicing times. The now closed units also provide the best possible protection for the texturing jets and lamellar chambers.

The 800-mm diameter cooling drum optimally and gently cools the filaments. And this has a positive influence on the yarn quality. The new cooling drum is now equipped with a V groove for all polymers (PET, PA6 and PP) as standard.

The RoTac3 tangling unit, already established within the market, once again reduces the compressed air consumption by around 50%, while the newly-developed Witras III-37 winder achieves production process speeds of 3,700 m/min.

First intuitively-operable human-machine interface (HMI)
The new BCF S8 is the first Oerlikon Manmade Fibers segment system equipped with the innovative human-machine interface (HMI) for intelligent controlling and monitoring. In this case, the interface between man and machine has been oriented on the daily requirements of users in BCF production. With its new ‘look and feel’, it supports intuitive operation and offers direct access to important information as well as actual and target values at each take-up position by means of a touch screen. A completely new ‘alarm philosophy’ also simplifies troubleshooting and malfunction analysis. “This smart HMI system is a logical step in the digitalization of our products”, explains Dr. Friedrich Lennemann, Vice President R&D Oerlikon Neumag.
