From the Sector

A typical manmade fiber system produces well over 600 tons of yarn a day. This equals in around 700 winders in filament yarn production or 3 systems in staple fiber production. These figures show just how important smooth production processes are.

If an error creeps into the process at any point, the daily waste increases dramatically. It is obvious that all yarn manufacturers want to prevent this happening to ensure their production facilities operate efficiently. Here, digitalization provides invaluable support. A Smart Factory that networks all steps within the production chain – including all auxiliary processes – identifies and reports quality deviations at an early stage. Yarn manufacturers can quickly intervene in the production process and hence avoid generating waste.

Digital solutions ensures process reliability
And the Smart Factory is also the focus of Oerlikon Manmade Fibers. Here, it comprises considerably more than the Plant Operation Center, a system that has been well-established within the market for many years now. “This is about absolute transparency and traceability. At the end of the process, yarn manufacturers are able to track at which position its finished textured yarn packages were spun and even have information on the processed granulate and the specific production conditions”, comments Ivan Gallo, responsible for digital products at Oerlikon Manmade Fiber. In this way, the Smart Factory ensures process reliability, above all. The data are automatically entered into the system and the product assessed at each stage of yarn production at which values and data are recorded – such as during visual inspection and when weighing. In the event of anomalies in the intermediate laboratory and quality checks, this allows yarn producers to intervene in the production process and correct these anomalies.

Information on the chip feeding, on the drying and on the masterbatch are available, as are data on the climate control, on the compressed air supply and on further auxiliary systems. With this, yarn manufacturers have at all times a complete overview of the ongoing production process, including comprehensive information on quality and production costs.

The Cetex Institut gGmbH, the thermoPre ENGINEERING GmbH and The FilamentFactory GmbH cooperate in the development, production and marketing of novel hybrid materials. The cooperation agreement signed on October 2, 2020 in Chemnitz takes the collaboration to a new level. "We are pleased to be able to supply the hybrid rovings to the end user not only in an application-specific manner, but also to offer the engineering for subsequent component applications, including the prototyping of the FRP components," says Sebastian Nendel, Managing Director of Cetex.

Patented process for the production of hybrid rovings
In the last 3 years the Cetex Institute has developed a plant technology for the production of hybrid rovings. By means of the patented process, different material combinations can be produced according to customer specifications. Material combinations of reinforcing fibers (glass, basalt, carbon, aramid or high-strength polymer fibers) can be combined with matrix fibers (PP, PET, PA, PPS, PEEK), but also special combinations of different reinforcing fibers or the combination of reinforcing fibers with metal fibers. Advantages of the new hybrid roving are the torsion-free and completely stretched fiber layer and the associated optimal utilization of the properties of the reinforcing fibers, as well as a very good homogeneity, whereby excellent processing can be achieved in later process steps.

Series production as next step
The next goal is clearly defined: Under the agreement, the process is to be jointly developed further by the project partners and transferred to series production. These joint activities form the basis for many years of intensive cooperation in this new field.

Mountains of waste, plastic-infested oceans, negative CO2 footprints – the need for more sustainable ways of living has never been more urgent. Consequently, it is logical that recycling solutions are becoming increasingly important within the textile industry. This was also tapped into at the first virtual Global Fiber Congress in Dornbirn with a session that focused specifically on the topic. In front of around 400 participants, Markus Reichwein, Head of Product Management at Oerlikon Barmag, also spoke about solutions currently on the market.

As one of only manufactureres, the Oerlikon Group’s Manmade Fibers segment offers the entire mechanical recycling chain –from preparing the recycled materials, producing the melt all the way through to the textured package. Here, the company utilizes the VacuFil solution supplied by its subsidiary Barmag Brückner Engineering (BBE) –which, in addition to mastering bottle-to-bottle and bottle-to-textile processes, is also able to process textile waste into chips. This permits the running of textile production operations very much in line with the zero-waste philosophy.

VacuFil ensures a stable process in the case of recycled quality yarns
The reliable removal of contaminants is vital for a stable and efficient spinning process and outstanding yarn quality. At the same time, stable operating conditions with minimal fluctuations are essential. The greatest challenge here is the differing qualities of the bottle flakes fed into the system, as the extrusion process is barely able to balance these fluctuations. Here, the VacuFil concept counters with blending silos, which reduce the differences in the viscosity of the polymers considerably and guarantee high yarn and fabric quality.

The VacuFil concept is installed upstream to an Oerlikon Barmag POY system, which transforms the recycled melt into filament yarn of the accustomed high quality. As texturing solutions, Oerlikon Barmag offers its state-of-the-art automatic eAFK-series systems, including the latest generation of the eAFK Evo, which was unveiled at the ITMA Barcelona last year. Yarn manufacturers wishing to continue texturing manually can use the eFK series.

With the VarioFil R+, producers of smaller batches now also have a compact system with an integrated recycled materials preparation unit at their disposal. The system offers a special extrusion system for bottle flake materials, the very latest metering and mixing technology for spin-dying and expanded 2-stage melt filtration. The four spinning positions are each equipped with an Oerlikon Barmag 10-end WINGS POY winder.

While mechanical recycling has already been extensively developed, chemical recycling for mixed fabrics is still presenting the textile industry with huge challenges. The Oerlikon Group’s Manmade Fibers segment is currently working on solutions and concepts for transforming these fabrics into new textiles.

• Industrial yarn: Capacity expansion in the high-end sector

Remscheid – the Chinese industrial yarn manufacturer Zhejiang Kingsway High-Tech Fiber Co., Ltd. is expanding its production capacities by a further 40,000 tons per annum with 5 Oerlikon Barmag lines. Kingsway is already successfully manufacturing special high-quality yarns, exclusively deploying Oerlikon Barmag industrial yarn systems.

The 21 new spinning positions will be used to manufacture a broad product range: in addition to super-low-shrinkage (SLS) and high-tenacity (HT) yarn, the business also plans to produce automotive yarns for seat belts and airbags. This flexibility is made possible as a result of the Oerlikon Barmag systems’ configuration. The new systems are expected to commence manufacturing next year.

Industrial yarns for greater safety

As a quality-conscious industrial yarn producer, Kingsway has been manufacturing its sophisticated, high-end yarns on Oerlikon Barmag filament yarn systems since 2015. Alex Yang Yu Long, CEO of Kingsway, is proud of relying on engineering artistry from Remscheid: “As expected, the yarns are first-class in terms of quality. Our products are used in safety equipment, sometimes in situations where lives depend on them. Therefore, there can be no compromises. To this end, we select our partners with the utmost care."

The National Council of Textile Organizations (NCTO), representing the full spectrum of U.S. textiles from fiber through finished products, issued a statement from NCTO President and CEO Kim Glas today in response to the administration’s plan to institute a 90-day deferral on MFN tariffs,  as reported by numerous press outlets.

The reported plan being pushed by the importing and retailing industries would defer certain tariffs, including those on finished apparel products. It is an ill-advised policy that will hurt the U.S. textile industry at the very time it is answering the call of the nation to produce medical supplies to battle the coronavirus pandemic. 

These unnecessary tariff concessions would benefit importers and retailers at the direct expense of manufacturers on the front lines of the COVID-19 response and send a demoralizing message.

Tariff deferrals would severely exacerbate ramifications for the U.S. economy, manufacturers and workers and open the floodgates for imports.

If the U.S. government makes tariff concessions during this crisis, it will be inviting a virtual tsunami of imports further devastating domestic manufacturing as it attempts to regain its footing.     

We urge the administration to abandon any moves to defer tariffs on finished products. It would only serve to allow importers to exploit the current crisis, while dealing a severe blow to U.S. manufacturing and its workers.

Perlon®, a Serafin Group company, is continuing to produce its’ quality filaments at all five sites for its’ customers in the current challenging climate. Production in China has been operating again as normal since the beginning of March after having to be temporarily halted due to the spreading of Covid-19. Production is now back up to 100%.

Production in Germany at our sites in Munderkingen (Baden-Wuerttemberg), Bobingen (Bavaria) and Wald-Michelbach (Hesse) as well as in the USA is continuing to run without any constraints. Therefore all sites are working to full capacity. In particular in the paper machine clothing area is showing an increase in sales which offsets a reduced demand in other areas such as automotive.

To manage the current situation responsibly, all hygiene measures at all our sites have been significantly increased so that the employees are protected as well as possible. There is hand sanitizer in every department and all of our production lines are disinfected several times a day. It has been explained to employees, what they should do in the current climate in order to minimise risk. Where possible employees are able to work from home. Perlon® has approximately 650 employees in Germany, over 80 in the USA and more than 100 in China.

High demand for monofilament for the paper industry
The paper industry is currently experiencing a rise in demand worldwide – and Perlon® is also benefitting from this, as customers need even more high quality monofilament and twisted yarns for the tensioning of paper machines. For the paper machine clothing field, Perlon® produced filaments are used to manufacture press fabric, which can be used either as a conveyor belt or for moisture removal on a paper production line. Due to the high mechanical strain through the presses, polyamide monofilaments or twisted yarns are therefore almost always used. Paper industry customers have increased their production recently. Whether it’s boxes to cope with the increased demand for online deliveries or paper for hygiene purposes (which everybody can identify with), there is an increased demand worldwide. The dental, hygiene and food preparation fields are also experiencing increased demand. To this end, Perlon® offers filaments for the manufacture of toothbrushes and high quality cleaning system brushes.

Long-term project business in China remains stable 

Oerlikon has received new large orders for manmade fibers production solutions from three of the world’s leading manmade fibers manufacturers. All three companies are based in China and have been key customers of Oerlikon for many years. The orders are for Oerlikon Barmag’s world-leading filament-spinning technology for the highly efficient production of polyester fibers. The three projects have a total value of more than CHF 600 million (EUR 565 million). A very small proportion of these projects will be recognized in Oerlikon Group’s order intake in 2020, and the majority will be accounted for in 2021 and 2022. On-site delivery and installation of these systems are planned for the period from 2021 to early 2023.

The systems business in China remains largely unchanged despite the short-term interruption caused by the coronavirus epidemic following the Chinese New Year celebrations. Long-term project planning for major customers in the manmade fibers industry has resulted in new major orders being placed with Oerlikon Barmag. One of the three new orders, valued at more than CHF300million (EUR282million), is the largest order ever received by Oerlikon Barmag, based in Remscheid, Germany.

The comprehensive manmade fibers technology solutions by Oerlikon are used along the entire value chain in polyester yarn manufacturing and contain cutting-edge automation and digitalization technologies. Oerlikon’s innovative technologies will enable the three Chinese companies to increase their production capacities for polyester yarn and to remain competitive. Oerlikon Barmag will provide the entire system for WINGS POY and WINGS FDY, as well as the texturing machines from the eFK product family in phases over a period of slightly over two years.

National Council of Textile Organizations (NCTO) President and CEO Kim Glas issued the following statement today in response to the Congressional-Executive Commission on China’s staff report on the forced labor of Uyghurs and other minorities in China to produce consumer products for global companies.

We share the concerns of the bipartisan China commission regarding forced labor in China that is used to produce goods for global companies. We agree with the findings and the commission’s recommendations to the administration and Congress to take action against the systemic abuse of forced labor.

As the commission’s report details, Chinese apparel exporters have clearly profited from the virtual enslavement of this minority population, and we call for continued scrutiny and the end to this exploitation of a repressed people. The commission has served a fair warning to U.S. businesses and consumers to not be complicit in these forced labor practices.

The Trevira CS joint booth at Heimtextil 2020 was once again a success.

Trevira looks back on a successful trade fair appearance at Heimtexil 2020. The concept of a joint booth together with customers along with the presentation of product innovations and a special exhibition dedicated to the contract sector has once again proved its worth. Trevira hosted 31 co-exhibitors thus increasing the number of participants again compared to last year. Members of the entire textile value chain were present at the Trevira stand: from the fibre production and yarn manufacture, to the colouring, weaving and warp and weft knitting stages, to the textile editor.

Klaus Holz, CEO Trevira GmbH: „We are pleased about the very positive feedback we got on our joint booth at Heimtextil 2020 from our customers and the visitors to our stand. It shows that our concept is successful and that the booth works well as a market place for Trevira CS.”

Product novelties were presented in an Innovation Park. Under the headline “Recycling at Trevira” the fibre producer presented its sustainable product range and diversified approaches to recycling: flame retardant fibres are produced from residual materials, which are reprocessed in an agglomeration plant. The recyclates are then deployed in the spinning facility to make new, high-quality products consisting of 100 % pre-consumer recycled material. Recycled, flame retardant filaments are produced from PET bottles and have a recycled content of 50 %. Standard polyester spun-dyed filament yarns are also available in a recycled version. Produced from PET bottles these yarns have a recycled content of 100 %.

In order to produce flame retardant fabrics which are also high-performing  in outdoor applications, Trevira now offers six more colours in addition to the existing colour range of 24 UV-stable, spun-dyed filament yarns. Trevira had been awarded the „Brandenburger Innovationspreis Kunststoffe und Chemie 2019“ for this innovation.

Cationic dyeable fibres and filament yarns enhance the Trevira portfolio of flame retardant specialties. They are used to create melange designs in fabrics, which still represents a strong trend in the home textile sector.

To meet the ever more complex demands of the market for more flexibility in design and additional functions as well as for sustainable products Trevira has introduced an enhanced Trevira CS branding concept, consisting of the three brands Trevira CS, Trevira CS flex und Trevira CS eco. Assigned according to product features, all of them stand for tested safety.

The Oerlikon Nonwoven experts will be presenting efficient solutions and comprehensive technology know-how for challenging filtration tasks to an international trade audience at the FiltXPO 2020 in Chicago, USA (Stand # 420), taking place between February 26 and 28.

Meltblown technology is one of the most efficient methods for producing very fine and highly-separating filter media made from manmade fibers. New, unique and highly-sophisticated filter media are easy to manufacture thanks to Oerlikon Nonwoven’s optimized meltblown technology. This process is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam, Furthermore, the novel guidance and distribution of the process air outside the coathanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures particularly homogeneous nonwoven properties and basis weights even in the case of delicate raw materials.

The Oerlikon Nonwoven charging unit stands out against other concepts currently available on the market. Users can freely choose from a large number of variation possibilities and set the optimum charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA- and HEPA-class filter media.

The new forming section ensures improved nonwoven formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixedfiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.
