From the Sector

In a judgment in December 2023, the Supreme People’s Court of the People’s Republic of China ruled in favor of Rieter in a legal dispute. The case concerned the infringement of a Rieter patent by a competitor’s draw frame. Rieter protects its innovations with patents and registered designs and consistently takes action against infringements of its intellectual property.

Rieter draw frames are known for their stable operation with high sliver quality and productivity. Scanning precision and autoleveling dynamics ensure outstanding sliver evenness and thus the production of high-quality yarns. Draw frames have also been the subject of a patent litigation by Rieter in China at various levels of jurisdiction. Rieter had sued a competitor for unauthorized use of its patented draw frame technology.

In the summer of 2022, the Shanghai Intellectual Property Court confirmed the patent infringement identified by Rieter and prohibited the accused competitor from continuing to use Rieter’s patented technology. The infringing party was also ordered to pay damages to Rieter.

The culpable competitor then appealed the decision of the Shanghai court to the Supreme People’s Court of the People’s Republic of China.

In December 2023, the Supreme Court of China in Beijing upheld the Shanghai decision, confirming that the patent had been infringed. As a result, Rieter’s competitor is prohibited from selling the infringing machine types and is required to pay the damages determined by the court.

This Supreme Court decision represents a major success for Rieter in defending its proprietary technologies in China. It is further proof that foreign companies can effectively defend their intellectual property in China.

As the technology leader in spinning machinery manufacturing, Rieter invests around 5% of its turnover annually in research and development. Rieter protects its innovative products with patents and registered designs and takes consistent action against infringements of industrial property rights.

Carbios inaugurated its textile preparation line at its demonstration plant in Clermont-Ferrand, in the presence of Mr. Lescure, French Minister for Industry. To streamline the textile preparation phase, which is currently carried out by hand or on several lines, Carbios has developed a fully integrated and automated line that transforms textile waste from used garments or cutting scraps into raw material suitable for depolymerization with its enzymatic biorecycling process. This patented line integrates all preparation stages (shredding and extraction of hard points such as buttons or fasteners), and provides Carbios with a high-performance, scalable development tool. The platform will help validate the biorecycling technology for textiles at demonstration plant scale (by 2024), and provides Carbios with expertise in working with collection and sorting operators to specify the quality of textiles and the preparation steps needed to make them suitable for enzymatic recycling. This expertise will also be invaluable to brands in the eco-design of their products.

Current collection, sorting and preparation infrastructures limit the amount of textile waste available for “fiber-to-fiber” recycling. Collection rates average around 15-25% worldwide^[1], and much of the waste collected is exported to Africa, Asia or Latin America for sorting.

Moreover, textiles are highly complex materials, with yarns of different composition (or nature) that are difficult, if not impossible, to physically separate. However, the highly selective enzyme developed by Carbios can specifically depolymerize the PET (polyester) present in textile material.

At present, textiles are sorted and prepared mainly by hand, with low yields, particularly for disruptors to recycling processes such as “hard points” (zips, buttons, etc.). To optimize this crucial phase, Carbios is contributing a textile preparation solution to accelerate the development of biorecycling in the textile industry. Enzymatic recycling, or biorecycling, therefore contributes to the construction of a textile recycling chain and the acceleration of textile circularity, also enabling brands to do away with used bottles.

At this year’s Techtextil India, the Polymer Processing Solutions Division of the Swiss Oerlikon group will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Between September 9 and 12, the discussions at Jio World Convention Centre (JWCC), Mumbai, will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
The yarns used in airbags 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 technol-ogies 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 - without any loss of function in any climate and for the lifetime of the vehicle

Buckle up!
Seat belts 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. “With our unique, patented Single Filament Layer Technology, we offer a sophisticated and simultaneously gentle high-tenacity (HT) yarn process for manufacturing these lifesavers and other applications made from industrial yarn”, explains André Wissenberg, Head of Marketing.

Road reinforcement using geotextiles
Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demand-ing 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 –  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.

100 days before ITMA 2023 in Milan, VDMA Textile Machinery launched its “Way2ITMA” webinar series. “Transforming the World of Textiles: efficient – digital – circular”. Under this heading, VDMA technology providers will present their solutions along the value chain.

Speakers of the virtual event were Dr. Janpeter Horn, Chairman of the VDMA Textile Machinery Association and Managing Director of August Herzog Maschinenfabrik, Dirk Vantyghem, Director General, EURATEX, Francis Elias Junker, Area Sales Manager, Andritz Laroche and Tanja Karila, Chief Marketing Officer, Infinited Fiber Company.

With regard to the EU strategy for sustainable and circular textiles, Dr. Horn said: “This topic concerns all of us, consumers and producers. We as machinery builders position ourselves as enablers. We want to be part of the solution of this ambitious project”.

Dirk Vantyghem introduced the core issues of the EU textile strategy launched in 2022, which is the most ambitious plan ever, to push the textile sector towards sustainability and transparency, and promote a new circular business model. If wrongly designed, that new framework may collapse the European textile value chain. But if done rightly, the changes ahead could bring a paradigm shift in the sector, where competitiveness is no longer based on price only, but also on sustainability and innovation, explained Vantyghem.

Francis Elias Junker showed high level of expertise for mechanical textile recycling for both spinning and nonwovens industries that Andritz has. The company has a diversity of solutions to offer and several cooperation partners, covering the value chain from recovery of fiber to the chemical modification and preparation for the production of yarn.

Tanja Karila gave an overview of how Infinited Fiber is turning textile waste into new fibers. Patented technology turns post-consumer textile waste into brand new premium quality fibers for the textile industry. The textile-to-textile recycling technology captures the value in waste that would otherwise be landfilled or burned.

The 11^th India ITME will take place from December 8.– 13., 2022, in Noida, India. Over 1,800 exhibitors and more than 150,000 trade visitors from the textile and apparel industry from all over the world are expected. Groz-Beckert will be presenting innovations from its various product areas..

India ITME takes place every four years and is the ideal technology platform for forward-looking innovations in the textile world. At the 11th edition of India ITME, exhibitors will be presenting their highlights from research and development across 15 halls.

The Knitting Product Division will be presenting several new products at India ITME: Among them the SAN™ SF staple fiber needle and the SNK SF staple fiber sinker, which are specially designed for use on large circular knitting machines. The division will also be exhibiting the SAN™ TT for application-related use in the field of technical textiles for flat knitting machines, as well as a needle which enables the advance into new dimensions of gauge in the flat knitting sector.

Groz-Beckert will also be demonstrating its competence as a system supplier in the field of warp knitting at the India ITME. The warp knitting machine needles and system parts from Groz-Beckert are precisely matched to one another and achieve a uniform and flawless warp knitting process.

With the WarpMasterPlus and the KnotMaster, the Weaving product division presents the latest generation of drawing-in and knotting machines from Groz-Beckert. They are particularly distinguished by their ease of operation and flexibility.

The product area Felting (Nonwovens) presents its product and service highlights for the nonwovens industry. These include the HyTec P jet strip for spunlace customers as well as the GEBECON felting needle, the dur needle, EcoStar felting needle and the Groz-Beckert customer product. The HyTec P-nozzle strip is characterized by improved handling and higher hardness. The patented GEBECON felting needle offers an improved surface finish and optimized breakage bending properties.

The Carding product area will present its further developments for the spinning industry. These include the new stationary flat series, the TV56 revolving top and the cylinder wire set with special tooth geometry. The new stationary flat series is characterized by an innovative tooth geometry and a new type of tooth distribution. The new TV56  revolving top with its new setting pattern and 560 points per square inch is particularly easy to clean. The improved cylinder wire convinces with its special and patented tooth shape, which has a positive effect on the maintenance effort. This makes it particularly suitable for quality-oriented cotton spinning mills producing high-quality yarns. Visitors can also look forward to the new InLine card clothing series for the nonwovens sector.

In the Sewing exhibition area, the focus is on technical textiles – in particular the manufacture of car seats. The answer to the high demands of sewing car seats is the special application needle SAN® 5.2 from Groz-Beckert. The special geometry gives it sufficient stability. The double groove at the point improves thread guidance and leads to a uniform seam pattern, especially in multidirectional sewing processes. The scarf chamfer on both sides of the needle prevent skipped stitches and optimize loop formation. The wear protection is increased by the titanium nitride coating GEBEDUR. In addition, the quality management INH will be exhibited and the functions and contents of the customer portal will be presented.

Reifenhäuser Cast Sheet Coating - specialists for cast film, sheet extrusion and extrusion coating lines - will showcase a new production process for cost-effective film/nonwoven composites with an exceptionally low grammage at ICE (International Converting Exhibition) Europe. The leading international trade show for paper, film, and foil conversion and processing will be held at Messe München (Munich trade fair center) from March 15-17, 2022.

The Covid-19 pandemic and current supply shortages have exposed the dependence of companies on global supply chains. This situation is both a warning signal and an opportunity to boost and reorganize the local production of semi-finished products from the ground up. Reifenhäuser Cast Sheet Coating has now developed a trend-setting production process termed Ultrathin Coating, in particular for the sector of medical protective clothing. The process will permit customers to produce particularly lightweight film/nonwoven composites with greater cost efficiency and, as a result, more competitively. The patent-pending process has several advantages: It cuts film grammage by 66%; material consumption in the overall composite is reduced by 28%; and it slashes costs by up to 34% compared to conventional semi-finished products. Significant cost savings are achieved in various ways, for example, by replacing hotmelt adhesives, which reduces line maintenance to a great extent at the same time.

Mark Borutta, Sales & Marketing Specialist bei Reifenhäuser Cast Sheet Coating, erklärt: „Wir erleben derzeit einen nachhaltig wachsenden Mehrbedarf für medizinische Schutzbekleidung verbunden mit einer Rückholstrategie für lokale Produktionskapazitäten. Vor diesem Hintergrund erzielen Produzenten mit ‚Ultrathin Coating‘ einen schnellen Return on Invest und hohe Profitabilität – auch bei einer Produktion innerhalb Europas.“ Die Vlies-erfahrene Schwesterfirma Reifenhäuser Reicofil –führender Hersteller von Vliesstoffanlagen – hat die Entwicklung unterstützt.

Mark Borutta, Sales & Marketing specialist at Reifenhäuser Cast Sheet Coating, explains: "We are currently experiencing a sustained increase in demand for medical protective clothing combined with a return strategy for local production capacity. Against this backdrop, producers achieve a fast return on investment and high profitability with Ultrathin Coating - even when production is based in Europe." The sister company, Reifenhäuser Reicofil, an experienced and global leading manufacturer of nonwoven lines, provided their support to the development.

Even if manufacturers already produce medical protective clothing and prefer to handle the coating process internally in the future instead of importing the necessary composites, it is worthwhile to set up an in-house production facility. In either case, the investment in Ultrathin Coating usually pays for itself in less than 12 months. The lower material input also reduces the consumption of fossil raw materials and this in turn responds to the increased demand for more sustainable products.

Fully integrated production lines from single source suppliers have increasingly become the norm in the textile industry and make complete sense in meeting today’s complex supply chain needs, according to TMAS – the Swedish Textile Machinery Association.

“Over the past few decades, textile mills have transitioned from consisting of collections of individual machines serviced and maintained largely by in-house mechanics as well as separate supplier companies for each part of the production line,” says TMAS Secretary General Therese Premler-Andersson. “Those in-house engineering service teams have diminished over the years, while the introduction of electronic drive systems in the 1980s and 90s also put an increased emphasis on the need for third party electrical engineers, operating separately to the machine builders.

“Subsequently, mechanical machines and electronic drive systems became much more integrated, and more recently, with the advent of digitalisation, entire production lines are becoming centrally controlled with remote, instantaneous connections to their suppliers for service and maintenance.

“In this context, the integration of machinery and automation specialists as single-source suppliers makes perfect sense, while partnerships between machine builders and their customers have never been more important.”

The recent acquisition of Nowo textile machinery from its previous owner, Brandstones Ab Oy, by TMAS member ACG Kinna, she adds, is a good example of this general trend.

Nowo, headquartered in Turku, Finland, designs, manufactures and exports high-end textile production machinery mainly for the fibre processing industry. At the end of the 1980s it introduced the highly successful Nowo Vac pillow filling system, which has been its best-selling system, alongside the Noworoll ball fibre machine, introduced in the 1990s.

Nowo’s machine range covers the entire production process from bale opening to weighing and filling, and complete production lines are tailored to the specific needs of customers. The company can also deliver individual machines such as bale openers, cards, cross-lappers, pickers, mixing devices, material silos, sucking devices, anti-static units etc. Seven patents cover the company’s technologies.

Founded in 1977, ACG Kinna Automatic, based in Skene in Sweden, specialises in customised and cost-efficient solutions for the production of pillows and quilts. All of its design, manufacturing and final line testing is carried out in Sweden and the reliability and longevity of its machines has earned it the trust of the world’s largest furniture and home decoration retailers and Europe’s largest manufacturer of pillows and duvets, among many customers.

Baldwin Technology Company Inc. will showcase a new generation of innovative technologies for optimized corrugated high-graphics package printing at SuperCorrExpo, taking place in Orlando, Florida, from Aug. 8 to 12.

The FlexoCleanerBrush™ enhances the print quality and improves worker safety in corrugated printing. The system automatically removes dust and contamination from the plate in seconds during production, without stopping the press. It also performs full end-of-job plate cleaning and drying in fewer than four minutes, enabling increased uptime and sustainability. A carbon fiber core keeps even the ultra-wide FlexoCleanerBrush to a minimal weight, and ensures cleaning is stable, uniform and consistent throughout the plate’s width. Because the system is fully automatic and spans the entire width of the plate cylinder, the FlexoCleanerBrush improves safety by eliminating routine operator contact with the machine, while also reducing the risk of cylinder nip injuries and contact with wash agents.

Also on view in Baldwin’s SuperCorrExpo booth, the FlexoDry™ is a fully integrated IR drying system, specifically developed for corrugated flexo printing presses. It reduces energy consumption by up to 30 percent over standard IR dryers through patented Diamond IR™ lamps. The system delivers improved drying results because of a unique optical design that produces higher intensity for enhanced color definition, and reduces or eliminates marking altogether, allowing for high-speed and full-confidence printing.

Additionally, Baldwin will showcase LED-UV technology, designed by its AMS Spectral UV division for wide-format flexo corrugated box printing.
