From the Sector

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them 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 technologies 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. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They 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.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding 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 – technological 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.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

Baldwin Technology Company Inc., an innovator of advanced color-management solutions and inspection technology for the printing industry, will present its “Complete Solution” for printing and inspection at the Tax Stamp and Traceability Forum, held May 16 to 18 in Malta.

Baldwin’s Complete Solution can be any combination of feeders (roll or sheet), vacuum tables, inspection systems, inkjet printers, UV ink-curing systems, reject gates and bins, sheet stackers, and real-time monitoring and reporting tools. Alongside Baldwin’s technologies, optional solution components can be joined together through partnerships with suppliers to create a world-class solution.

For advanced defect detection, Baldwin’s Guardian PQV 100% Print Inspection camera systems can be mounted on one or both sides of the product to perform 100% print-quality inspection, verify variable data and inspect the most challenging security print features. The system offers lighting options for all materials and substrates, as well as for special applications, including holograms, covert serialization, covert security features and more. The Guardian PQV can also be retrofitted to existing presses, machines and transports.
 
As part of a data-connected defect-management workflow, the Guardian PQV is a feature-rich inline defect-detection system that enables printers to find and remove defects quickly—and monitor their processes to prevent defects from occurring again or repeatedly. This technology provides complete print-quality verification from prepress through production, reporting and archiving for perfect runs.

Baldwin recently realigned its sales teams to optimize service and simplify access to its process-improvement and consumables technologies for printing and packaging customers in more than 100 countries. Two new sales professionals have since joined the team, covering smaller regional geographies and providing customers with a single point of contact for all of Baldwin’s product lines.

The Techtextil and Heimtextil Summer Special exhibitions, taking place together in Frankfurt from June 21-24, represent an opportunity for Monforts to showcase its finishing and coating technologies for two of its major markets – especially at a time when energy prices continue to soar for textile manufacturers in Europe.

Existing customers of Monforts include many manufacturers in the field of home textiles, as well as those making geotextiles, automotive fabrics and other functional materials – all of whom will be well represented in Frankfurt this June. Dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics, as well as high-temperature filter materials.

Energy prices are rising steeply everywhere and a particular emphasis for Monforts in Frankfurt will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as better insulation of the treatment chambers or the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The modular system for heat recovery can also be extended for exhaust air cleaning and odour elimination. Monforts can provide a range of further resource-saving and energy recovery options tailored to each individual line installation including modification of the heating source.

With the Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

All of these very different materials require coating and finishing for maximum efficiency, using Monforts technologies which provide the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

The Monforts EcoApplicator offers further potential for sustainably achieving perfect finishes via a precise direct application system, as an alternative to conventional padding – where fabrics are immersed in a bath of the required finishing chemicals. It can significantly further reduce the energy and water required and finishes can be applied on just one side of the fabric, or both, and even separately on each side, to be sealed in place via different heating zones in the stenter.

A new interview study from NGO ChemSec shows that there is a gap between supply and demand when it comes to recycled materials, causing confusion and bottlenecks. Among other things, suppliers go out of their way using elaborate trade schemes to reach the coveted ”100% recycled” tag, which – it turns out – is not that important to consumer product brands. Far more crucial aspects, according to several major B2C companies, are:

• Honest communication towards customers
• Comprehensive information from suppliers
• Clear standards for recycled material

These are some of the conclusions from NGO ChemSec’s survey and interview study with 26 highly well-known consumer product brands. All brands responded to a survey concerning their current plastic use, as well as their needs, expectations and challenges regarding using more recycled material, to enable the shift to a circular economy for plastics.

Ten of the brands then participated in in-depth interviews on the same topics:, Essity, H&M, IKEA, Inditex , Lego, Mars,  SC Johnson, Tarkett, Unilever and Walgreens Boots Alliance.

Is non-mechanical recycling the answer?
Only about ten percent of all discarded plastics is recycled today, which is of course not nearly enough to achieve a circular plastics economy. Despite ambitions and initiatives to reduce plastics use – replacing the materials with other, more sustainable ones – the “plastic tap” is not expected to be turned off anytime soon. Quite the opposite, which makes raising the recycling rates more important than ever.

Although commercially viable, traditional (mechanical) recycling is afflicted with severe flaws, such as legacy chemicals, quality and functionality issues, as well as the lack of clean and sorted waste streams. The brands cited quality and functionality issues as the main obstacles for using more recycled material in their products.

This opens up for non-mechanical recycling, sometimes referred to as chemical recycling, where the plastic is either dissolved or broken down into smaller building blocks. Harmful additives and other hazardous chemicals can be removed in the process, and a material comparable to virgin plastic can be achieved – at least in theory.

So far, however, non-mechanical recycling technologies are costly, energy-intensive, and often require the addition of a great deal of virgin plastic to work – the very material that needs to be phased out.

The chain of custody models needs to be detangled
Apart from these production issues, there is a wide range of chain of custody models surrounding non-mechanical recycling, including mass balance and book & claim, which enable trade of credits or certificates for recycled material.

This cuts the physical connection between input and output, making it possible for a supplier to sell a material as “100% recycled”, when the actual recycled content could be zero.

This is a major issue for the brands ChemSec has spoken to, who value honest and correct communication towards customers. It turns out, perhaps somewhat surprisingly, that being able to slap a “made from 100% recycled plastic” label on a product is not all that important to brands.

To the brands, a physical connection between input (the discarded plastic waste headed for recycling) and output (the product at least partially made from recycled plastics) is far more important.

A physical connection, along with correct and adequate information from suppliers, as well as clearer standards and guidelines than what is available today, is what brands require to increase the use of recycled material and move us closer to a circular economy for plastics.

ISKO joins hands with Paolo Gnutti to break exciting new ground in the world of premium, luxury denim. Both will respectively bring together their expertise in advanced responsible denim technologies and refined fabrics’ elevation, resulting in special ISKO™ Luxury collections by PG, characterized by a high-end appeal.

“ISKO is thrilled to collaborate with Paolo Gnutti, one of the most respected personalities among the denim community.” claimed Marco Lucietti, Director of Strategic Projects, ISKO. “It is a wonderful moment for us to inspire the whole industry with the most revolutionary technological innovations, highly profiled to the unique needs of the luxury segment and we know that Paolo’s creative touch will bring out the very best of ISKO denim’s qualities.”

“The collaboration with ISKO is exciting on so many levels” explains Paolo Gnutti, PG founder. “The company pioneers game-changing technologies in quality, performance and sustainability for the world of denim which is extremely interesting for me to explore for the luxury aesthetic. We will be working with new and exclusive fabrics that will bring a unique twist to the world of fashionable luxury denim. Together, we will really energize the premium sector.”

ISKO is back at the Denim Première Vision in Berlin from 17-18th of May.

Chemistry plus creativity” is Officina39’s new tagline expressing the most important values at the core of the company’s approach, founded on a deep understanding of sustainability. Embracing the “plus” that used to feature as part of the Officina39 logo, it now takes the shape of a true formula of innovation that echoes throughout the renovated brand look that the company is introducing for the first time at Kingpins.

The latest addition to the Trustainable™ collection is Aqualess Fade, a technology that recreates the bleaching effect of chlorine on fabrics, a waterless special compound for the discoloration of denim on indigo/black garments which is reducing resource consumption and environmental impact. This innovation completes and integrates Aqualess Mission, a combination of technologies that allows garment laundry processes to reduce 75% of the water use.

Traditional systems usually use about 52 liters of water for a pair of jeans, while Officina39’s cutting-edge technology employs only 12.5 liters without affecting the quality of the final product. Until now, the process included three eco-friendly technologies: Novascraper Indigo, a laser finishing technique that adds a natural, vintage look to denim garments; OZ-ONE Powder, an advanced product to give garments a bleached yet eco-friendly treatment, for a worn and distressed look; and Aqualess Aged, a waterless compound to give denim abrasion effects.

“In our field, the word “less” is to be found pretty much everywhere you look: less water, less energy, less impact and the list goes on. So I asked myself if we could work on implementing the word “plus” in this collection.” stated Stefano Parrotta, Officina39 Technical Manager. “And the answer, of course, was yes: we thought of all the ways in which the idea of more (plus) best represents what we do – more passion, more creativity, more collaboration, more inspiration, more Officina39. I think it is important to look for what the industry needs more of and the word “plus” perfectly embodies that!”

Construction machinery rolls into action again. The ground-breaking ceremony at the EREMA site in Ansfelden on April, 6 signals the start of work on a new R&D centre. Two halls with a total area of 1,550 square metres and a new office building with 50 workplaces will be built. The R&D centre will offer cross-departmental and cross-company test machines and laboratory for research and development of plastics recycling technologies to further advance the circular economy. Completion is scheduled for February 2023.

Plastics recycling is currently evolving very rapidly from a niche to a trend. This is driven by the legislative targets for plastics recycling that the European Union and many countries around the world have enacted, as well as by the European Green Deal, which aims to make Europe the first climate-neutral continent and in which the circular economy plays a very central role.

However, there is not just one recycling solution for all types of plastic waste, but rather different solutions depending on the type of plastic, the product and the application intended for the recycled plastic. While some plastics processing loops, such as for PET bottles, have already been closed, many other plastic waste streams still require a great deal of R&D in cooperation with everyone involved in the value chain to produce recycled pellets that meet the very highest standards for the production of new products. More space will be available for this in the new centre.

R&D is decentralised at EREMA. In recent years, approximately 5 percent of turnover was reinvested annually in research and development. Employees from different departments handle process engineering challenges, innovations in mechanical engineering and automation technology, and special technologies with a view to further improving the quality of recycled pellets. They also focus on new recycling technologies for waste plastic materials for which there is currently no satisfactory circular economy solution. The decisive factor here is also to exploit the potential of digitalisation. By collecting and analysing machine data, not only can recycling processes and product quality be further improved, but we can also develop our digital service offering for our customers. Such offerings include customer-specific information tools that feature plant and process data, predictive maintenance and online support as well as commissioning via remote access.

For material tests, which are necessary for research and development work, an expanded machine park will be available following completion of the new R&D centre. Here, the recycling process can be evaluated end-to-end, including upstream and downstream processes such as shredding and further processing of the recycled pellets. The material tests are supported by detailed analysis in the professionally equipped laboratory, which will be relocated to the new premises and upgraded where necessary with the very latest lab equipment.

In 2021, nonwovens production in Greater Europe increased in volume by 2.0% to reach 3,120,967 tonnes (and 87.6 billion square metres).

EDANA, the international Association serving the nonwovens and related industries today released its statistics on Nonwovens Production and Deliveries for 2021. Following the impressive growth recorded in 2020, the updated figures for Greater Europe (incl. Western and Eastern Europe countries, Turkey, Belarus, Russia and Ukraine) highlight again the ability of the European industry to innovate and to invest in order to meet the challenges of the pandemic crisis.

In 2021, nonwovens production in Greater Europe increased in volume by 2.0% to reach 3,120,967 tonnes (and 87.6 billion square metres). Since 2019, the European output increased by nearly 9%.

Jacques Prigneaux, EDANA’s Market Analysis and Economic Affairs Director commented “This 2% average growth is in line with European forecasts disclosed in October 2021 in our Global Nonwoven Markets 2020-2025 report. In 2021, significant growth areas for nonwovens were recorded in building construction (+17.4%), agriculture (+11.3%), electronic materials (+10.1%) and air filtration (+9.1%). Countering this, a further decline of -1% was recorded in automotive interior applications. In some market segments, a comparison with the pre-COVID situation is probably more relevant. This is particularly true in hygiene, medical and wipes nonwovens, which were almost flat or slightly decreasing compared to the level reached in 2020, but still much higher than in 2019”.

He added: “Looking at the different production processes of nonwovens, various trends were observed in 2021. The production of fiber-based materials, including Drylaid, Wetlaid, and Airlaid technologies, recorded divergent growth rates (respectively +2.4%, +1.1% and -4.8%), and spunmelt nonwovens recorded a growth rate of +3.1%. In Drylaid, the highest growth in tonnes was observed in needlepunched, with a 6.4% increase. The production of drylaid-hydroentangled, which peaked in 2020, was at the same level a year later”.
