From the Sector

Neumünster – Oerlikon Neumag has successfully commissioned three staple fiber bicomponent systems in China. With capacities of 50 tons per day each, the systems are being used to manufacture coresheath bicomponent fibers made from PP/PE or PET/PE at two long-standing Oerlikon Manmade Fibers customers. These fibers are used to make hygiene products.

Oerlikon Neumag staple fiber technology still in demand

Despite coronavirus-related restrictions, the three new systems were installed within three and five months, all without any problems. They have meanwhile been operating under stable production conditions with optimum fiber quality of the very highest standards for several weeks now.

Many years of experience in bi-component spinning

Oerlikon Neumag looks back on many years of experience in constructing bicomponent staple fiber systems. The first system for this fiber type was commissioned as far back as 1995. Oerlikon Neumag offers solutions for the most varied cross-sections, ranging from sheath/core’, ‘side-by-side’, ‘island in the sea’, ‘orange type’ as well as ‘trilobal’. The applications are diverse: from self-crimping fibers, bonding fibers, super-microfibers all the way through to hollow fibers.

The Oerlikon Neumag bicomponent technology is particularly characterized by the extremely robust spin packs that have no expensive wear parts, which considerably reduces the costs here. The reconditioning costs when cleaning the spin packs are kept to an absolute minimum. Add to this the separate temperature transfer option in the spinning beam for the two polymers. As a result, the quality and the viscosity of the polymers can be accurately adjusted in accordance with the respective process requirements.

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.

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.

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.

Originating in Switzerland and founded in 1853, Saurer is a leading globally operating technology group focusing on machinery and components for yarn processing. After having participated in the first CIIE last year, Saurer will once again take part in this important event this year, presenting its new air-spinning machine Autoairo, which the company launched at ITMA Barcelona on 20 June 2019. At the CIIE in November, the Autoairo will be exhibited in Asia for the first time.

Autoairo has set new benchmarks for air spinning. Saurer has combined its most advanced automation solutions with proven technology to create an air-spinning machine with unique properties. The Autoairo features autonomous spinning positions with individual drives and integrated intelligence. Its digital piecing unit is capable of performing up to 24 piecing processes simultaneously. As a result, the machine’s run-up time is also reduced by at least 30%. The Autoairo’s compact, double-sided design means that it takes up 40% less space than single-sided machines. These features give the Autoairo a powerful productivity advantage, while at the same time lowering spinning costs.

•    Stronger, softer nylon polyamide fibers plus fast processing for clothes, carpets & industrial applications
•    AddWorks blends lower total cost of ownership & reduce production complexity while enhancing performance

Muttenz, May 3, 2018 – Clariant, a world leader in specialty chemicals, introduced new additive solutions for plastics materials at Chinaplas 2018.

“Our innovations focus on higher performance at better convenience for a sustainable future,” says Stephan Lynen, Head of Clariant BU Additives. “At Chinaplas 2018 we demonstrated our technical and market capabilities around the theme of e-mobility. The immense changes in mobility call for lighter, safer and smarter vehicles. We offer new additive solutions, such as AddWorks, and technical capabilities to respond to this demand. We are accompanying this with a series of investments such as new production facilities in China.”

Clariant’s new AddWorks solutions – AddWorksATR 146, AddWorks LXR 568 and AddWorks TFB 117 – are specifically aimed at improving performance and efficiency of plastics materials for compounders, polymer and fiber producers in China’s major plastics manufacturing segments. All three solutions are part of the globally available portfolio.

The full AddWorks portfolio consists of differentiated market-specific synergistic additive blends that streamline production processes and create value for customers while enhancing performance. Each solution is customized to specific market needs, underlined by broader considerations such as emission reduction, and less energy and resource usage.

Sustainability and performance for the world’s largest auto market
To support the significant investment in electric vehicles in China, Clariant launched two additive innovations that improve the lifetime of lightweight automotive parts and under-the-hood applications and reduce VOC emissions in an easy to use single solution.

AddWorks ATR 146 is a new low dosage, sulfur-free heat and light stabilizer for filled polypropylene (TPO) compounds used in interior applications. Its exceptional heat and light stability and long term color retention offers the automotive industry unmatched performance. It shows no surface cracking after 700 hours at 150°C, which enables dashboards, instrument panels, door panels and pillars to maintain their aesthetics longer than with traditional stabilizers. It also contributes to reducing blooming and VOC emissions, supporting the common effort to make automotive interiors healthier and odorless.

AddWorks LXR 568 is a high performance processing stabilizer that helps to prevent plastic resins, especially polyolefins, from degradation at high processing temperatures. For the automotive industry, this reduces the tendency of injection molded polypropylene interior car parts to turn brittle during heat exposure, enabling them to maintain a defect-free surface. It also has low migration and low fogging that support healthier in-cab environments.

AddWorks LXR 568 combines outstanding color and melt flow protection with good resistance to hydrolysis and high thermal stability. This makes it ideal for interior and under-the-hood powertrains and wider application areas such as packaging films. It is available in free-flowing pills and micro-pills which are easy and convenient to use.

Softer, stronger polyamide fibers for clothes, carpets and industrial applications
Within the next three years, China is expected to account for 40% of the world’s nylon production and more than 30% of the nylon resin consumed globally[1]. The new AddWorks TFB 117 offers a number of benefits to help stabilize and smoothen fiber production processes, protect color, and improve heat stability and mechanical properties of fibers. AddWorks TFB 117 ensures smooth spinnability with less filaments breakage, even at low processing temperatures and at high speed spinning up to 5,500 m/min.

Martin P. J. John, Head of BL Performance Additives at Clariant, comments: “AddWorks solutions are an ideal fit with China’s priority of achieving more sustainable production. They save time and reduce complexity along the production process, with easy to use formats that reduce health risk and chemical waste. Our new state-of-the-art production facility in Zhenjiang, China, which opens later this year, is dedicated to the manufacturing of AddWorks to deliver innovative solutions tailored to the needs of the market. Made for China in China.

In addition to AddWorks, Clariant presented Exolit® OP 1400, a highly stable non-halogenated flame retardant enhancing safety during the charging process. It also provides outstanding thermal stability for under the hood applications. Exolit OP 1400 has been awarded the Clariant EcoTain® label for outstanding sustainability and performance.  

Clariant also introduced two ranges of performance waxes that smoothen the production of automotive plastics for under the hood applications, Licowax® and Licocare® RBW. The recently launched Licocare RBW is a series of multi-purpose additives based on crude rice bran wax. They offer better shaping flexibility, better mechanical properties and enhanced surface finish, which results in a reduced rejection rate and a more effective dosage.

Bobingen - On the 4th October 2017 a new brand was introduced at Trevira: Trevira SINFINECO®. This label may be carried by all textiles that contain sustainable Trevira products. Sustainable, innovative, high-value and responsible – these are the values the new brand stands for.

As an industrial enterprise, Trevira is conscious of its special responsibility for an intact environment and has long advocated the recycling of valuable raw materials and waste products. Trevira CEO Klaus Holz: “We at Trevira wish to preserve the environment and at the same time work to create value. These are the criteria of our sustainability concept.“

Creation of the new brand is therefore only a logical step, one that enables customers to label their sustainable Trevira products as such. Trevira is known for the high quality of its products. In every way recycled products are as good as the original materials in terms of quality and performance.

Two vital elements in Pre-Consumer Recycling and an important concept in Post-Consumer Recycling form part of the sustainability strategy of Trevira to conserve resources and maintain value. :

In the area of Pre-Consumer Recycling, on the one hand, residual materials resulting from the manufacture of polyester fibres and filaments in Bobingen and Guben, dependent on the manufacturing step, are processed in the agglomeration plant and restored to become serviceable primary material. The recyclates are then fed back to our fibre and filament spinning mills, to be made into new top-quality products.

On the other hand, in fibre production there occurs in the manufacture of tow a small proportion of tow that cannot be used for converting and has to be cut out. Instead of selling this material as waste, it is cut up, pressed into balls and then carded / combed by a partner, resulting in a 1A quality product. The GRS certification (Global Recycled Standard) is requested for this. As with converter tow from new material, the recycled tow is mostly incorporated into polyester wool blends (55 % PET / 45 % wool), which are used primarily in corporate wear and uniforms.

In the area of Post-Consumer Recycling, Trevira offers filament yarns consisting of 100 % recycled PET bottles. Our parent company Indorama manufactures very high quality recycled chips from PET bottles. Since only transparent PET bottles are used in Thailand, the flakes and chips are of a particularly good and very uniform quality. The recycled chips, fibres and filaments from Indorama bear the GRS certificates (Global Recycled Standard) and RCS-NL (Recycled Claim Standard). Trevira processes the regranulate made by Indorama from bottle flakes into filament yarns consisting 100 % of recycled material. The filament yarns are available in titres 167 and 76 dtex normal polyester. Alongside technical applications, they are used in the automotive and apparel sectors. In addition, many promising developments with the recycled material are on their way.
