From the Sector

This month, the circular knitting machine manufacturer Mayer & Cie. is launching its upgrade kits for circular knitting machines that are already successfully in use by customers. With tailor-made packages, the company wants to give its users the opportunity to take advantage of technological progress in their existing machines. The aim is to improve the performance of the existing machines and to extend their service life. In addition to the machine-specific upgrade kits, the company now starts offering tailormade spare parts packages. They are intended to ensure machine availability and equip customers with spare parts for standard situations. In addition, they offer a degree of independence from possible failures in the supply chain and rising transport costs.

Longevity, a popular product property
“Longevity of our circular knitting machines is definitely a property that our satisfied customers mention regularly”, Mayer & Cie. sales director Wolfgang Müller says. The company estimates that up to 50 percent of all the circular knitting machines it has ever made are still around in the market somewhere.

Upgrades boost performance and value
Value retention, maintenance and upgrades for existing machines are a key issue for the company – and for the customers who successfully use existing Mayer & Cie equipment. That’s why the company recently launched customised upgrade kits to improve the long-term performance of machines.

Low budget, clear benefit
Compared to a new machine, upgrade kits are a low-cost investment that deliver clearly defined benefits. For example, an improved yarn guide ensures a significant increase in the plating reliability and output of the machine in question.

Most of the upgrade kits is machine-specific; the aforementioned yarn guide ensures a boost in productivity for the Relanit 3.2 II and Relanit 3.2 S. For S4 machines an optimised fluff blowing device can be the solution. It ensures that less fluff is knitted in and thereby improves the fabric quality. It also reduces downtimes that would otherwise be required for cleaning. Upgrade kits suitable for most Mayer & Cie. machines are the edge trimmer to open a fabric hose before the fabric’s rolling-up and the laying facility for high-quality hose fabric.

Spare part packages: Inside is what is required
In addition to individual upgrade kits Mayer & Cie. now offers spare parts packages. They too are customised for individual machines. When purchasing a machine, the customer can also order a small or a large spare parts package. Selected specially for the machine in question, it contains the most important consumables and spare parts.
The new spare parts packages also increase customers’ independence of supply chain failures and rising transport costs.

• Innovation begins with creativity
• A pioneer of the manmade fiber industry

When the manmade fiber age began a century ago, a German company was responsible for the pioneering work involved. Barmag, established in 1922, was one of the world’s first companies to construct machines for the large-scale production of synthetic staple fibers. To this day, the leading manufacturer of manmade fiber spinning systems and texturing machines in Remscheid – a brand under the aegis of the Swiss Oerlikon Group since 2007 – has shaped technological progress in this sector; in future, with ever more innovations focusing on sustainability and digitalization.

Barmer Maschinenfabrik Aktiengesellschaft (Barmag) is founded in Barmen, located in the Bergische Land region, on March 27, 1922. The German and Dutch founders enter unchartered technological territory, one created as the result of a groundbreaking invention: in 1884, French chemist Count Hilaire Bernigaud de Chardonnet used nitrocellulose to produce the first so-called artificial silk, later known as rayon. The following decades see rapid development focusing on the search for synthetic textile fibers and their manufacturing technologies. As one of the first machine factories, Barmag battles its way through the eventful early years of the manmade fiber industry, the ‘Roaring Twenties’ and the Great Depression – and suffers the extensive destruction of its factories at the end of World War Two. Rebuilding is successful. With the unstoppable success story of purely synthetic plastic fibers such as polyamide, the company flourishes from the 1950s through to the 1970s, establishing sites in all international, for the textile industry at the time important, industrial regions and garnering prestige across the globe in the process. In the ups and downs of expansion, global competition and crises, Barmag reaches the very pinnacle of the market and becomes the preferred technological development partner for the manmade fiber industries in China, India and Turkey. The company has been a high-impact brand under the umbrella of the Oerlikon Group since 2007.

On the wings of innovation
Today, Oerlikon Barmag is a leading supplier of manmade fiber filament spinning systems and part of the Manmade Fibers Solutions business unit of the Oerlikon Polymer Processing Solutions Division. And our aspirations have not diminished: “The striving towards innovation and technological leadership has been, is and will always be part of our DNA”, emphasizes Georg Stausberg, CEO of Oerlikon Polymer Processing Solutions. In the past, this has been observable in such trailblazing innovations as the revolutionary WINGS generation of winders for POY in 2007 and WINGS for FDY in 2012. Currently, the focus of new and further developments is very much on digitalization and sustainability. Here, Oerlikon Barmag has – as one of the world’s first systems manufacturers – been implementing fully-networked smart factories for globally-leading polyester manufacturers since the end of the last decade. Within this context, digital solutions and automation are also helping to provide greater climate and environmental compatibility. This sustainability commitment is not only evidenced by the e-save label introduced for all products back in 2004: Oerlikon is endeavoring to also make all its sites carbon-neutral by 2030 and to acquire its energy exclusively from renewable sources. An ambitious target, whose achievement could be helped by the Oerlikon Barmag anniversary, states Georg Stausberg: “Innovation begins with creativity. And remembering the past provides plenty of motivation and inspiration for the future.”

BB Engineering GmbH (Germany) delivers a melt filter for recycling PET flakes to polyester manufacturer Indorama Polyester Industries (Thailand). Indorama will be using the type NSF38 filter in its recently assembled recycling system in order to produce rPET granulate from flake PET bottle waste. The NSF38 filter enables continual filtering – in other words, the system switches from one filter to the other during the process without the need for conversion shut-downs. The filter allows the processing of consumer waste for example, in the form of shredded PET bottles into new, high-quality rPET granulate. This granulate is subsequently processed into manmade fibers in spinning systems.

The NSF38 is a switchable filter with a filter surface area of ap-prox. 16 m2 on each side, with throughputs of between 1,000 and 1,900 kg/h. The filter inserts each contain 19 pleated filter candles (60 x 1,000mm Ø). The filter medium comprises a sin-tered metal fiber nonwoven with a filtration fineness of 25 μm. This ensures that the melt remains free of contaminants and gel particles, which in turn enables the production of high-quality end products.

Korteks, one of the world’s biggest yarn producers based in Bursa, Turkey, has started the production of recycled polyester filament yarn in its production facility using a Starlinger recycling line.

With the new recycling facility, which comprises a total closed area of 17,000 m² and has a monthly production capacity of 600 tons, Korteks was able to reduce the production waste at its virgin PES yarn site to zero.

The Starlinger recoSTAR universal 165 H-VAC iV+, which is part of Korteks’ 10 million dollars investment in a new polymer recycling facility, took up operation in May 2021. It has a production capacity of 7,200 tons per year and currently processes clean in-house polyester fibers from production scrap together with washed post-consumer PET flakes at a ratio of 50/50. Korteks uses the polyester regranulate at a share of 100 % for its new polyester filament yarn line it is going to market under the name “TAÇ Reborn”. With this investment, the company has made an important step towards establishing a circular economy in the Turkish textile industry.

The Starlinger recycling line is the first of its kind in Turkey and is equipped with special components for filament yarn recycling. A RSC (Rapid Sleeve Changer) candle filter developed by Starlinger ensures finest melt filtration down to 15 μm. It has been specially designed for polyester recycling and reaches an output of 1000 kg/h. For continuous operation the filter elements are changed “on the fly” without interrupting production, which significantly limits melt loss.

The viscoSTAR SSP unit at the end of the recycling process guarantees consistent IV increase according to the first-in-first-out principle. This makes sure that the produced regranulate has the ideal properties required for filament yarn production. The technical configuration of the line does not only allow the processing of a polyester fiber/PET flake mix as input materials, but also 100 % polyester filament scrap or 100 % PET bottle flakes.

Korteks expects the recycling market in general to grow as there is increased acceptance for recycled products in the society, and predicts the need for recycling solutions also for other synthetic and natural fibers.

• Introducing TexCoat G4 to US textile industry
• Non-contact precision spray fabric-finishing system enhances sustainability and process control

Baldwin Technology Company Inc. will be showcasing its TexCoat G4 non-contact precision spray fabric-finishing system at the Techtextil North America trade show, held Aug. 23 to 25, in Raleigh, North Carolina.

With extensive sustainability benefits, unprecedented tracking and process control, and Industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, and significantly reduced water and energy consumption.

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides.

Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection. The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption.

Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.
