From the Sector

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.

To reach its goal of being the world’s leading supplier of enhanced recycled polyethylene terephthalate (PET), gr3n is signing a binding Memorandum of Understanding (MOU) with its shareholder Intecsa Industrial to set up a Joint Venture.

gr3n together with Intecsa Industrial will join forces and build a “First-of-a-Kind” manufacturing facility able to produce 40.000 tons of virgin-like PET, commencing EPC phase in Q4-2024 and aiming to be operational in 2027. gr3n’s chemical recycling technology is capable of processing PET from various industries including textile waste, closing the loop for hard-to-recycle PET applications.

The world’s first industrial-scale MADE PET recycling plant will have the capability to process post-industrial and post-consumer PET waste including hard-to-recycle waste, to produce approximately 40.000 tons of virgin PET chips from the recycled monomers saving nearly 2 million tons of CO2 during its operating life. The post-consumer and/or post-industrial polyesters will be both from bottles (colored, colorless, transparent, opaque) and textiles (100% polyester but also mixtures of other materials like PU, cotton, polyether, polyurea, etc. with up to 30% of presence in the raw textile).

The technical concept of the MADE plant is to break down PET into its main components (monomers) so they can potentially be re-polymerized endlessly to provide brand new virgin PET or any other polymer using one of the monomers. Polymers obtained can be used to produce new bottles/trays and/or new garments, essentially completely displacing feedstock material from fossil fuels, as the recycled product has the same functionality as that derived traditionally. This means that gr3n can potentially achieve bottle-to-textile, textile-to-textile, or even textile-to-bottle recycling, moving from a linear to a circular system.

gr3n’s process has the potential to change the way PET is recycled worldwide, enabling huge benefits for both the recycling industry and the entire polyester value chain. Many efforts have been made in the past to transfer enhanced recycling from research laboratories to the manufacturing industry, but the economics and skepticism of the first adopters have constantly blocked the progress of the proposed solutions. Thanks to the MADE technology developed by gr3n, this approach is now feasible and makes gr3n one of the few companies with the potential to provide a reliable enhanced recycling solution that closes the life cycle of PET, and also offers food grade polymer material, processes a large variety of waste and reduces the carbon footprint of these materials usually destined for incineration or landfill.

B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

Around EUR 355 million in overall turnover, 350 extruders delivered creating an additional recycling capacity for 1.6 million tons of recycled pellets as a result - these are the figures with which the EREMA Group was able to close the 2022/23 financial year in March.

"With demand for recycled plastics remaining high, the past financial year brought many challenges that we needed to handle," says Manfred Hackl, CEO of EREMA Group GmbH. The challenges included persistent delays in the supply chain and unexpected supplier outages. Logistics and production processes had to be adapted several times as a result. The situation has improved significantly meantime as a result of these measures and more stable supply chains.

The production locations in Austria manufactured 270 extruders and delivered them to customers around the globe. Taking the whole group into consideration, this figure rises to 350 including the extruders from PLASMAC, the Italian subsidiary. The recycled pellet production capacity of all extrusion systems delivered in financial year 2022/23 adds up to around 1.6 million tonnes per year. On top of that there are around 130 additional components and modules such as filter systems and ReFresher anti-odour units.

Recycling innovations for high-quality pellets
K 2022 - the highlight trade fair of the past financial year - saw the EREMA Group launch seven
new recycling systems and components. These included the new INTAREMA® TVEplus® DuaFil® Compact recycling system and the EcoGentle® plasticising unit, which was also newly developed. Thanks to their gentle polymer treatment and significantly lower melt temperature, both extrusion innovations deliver effective advantages in terms of the quality of the melt, recycled pellets, and final product, as well as impressive energy efficiency in post consumer and PET recycling applications. The significance of these innovations for plastics recycling is underlined by the nomination of the DuaFil® Compact technology for one of this year's Plastics Recycling Awards Europe in the category Recycling Machinery Innovation of the Year.
The same applies to the READYMAC 1109 TVE machine made to stock by EREMA Group subsidiary UMAC, as well as to the new ALPHA XS edge trim recycling machine for the inhouse recycling segment made by PLASMAC. The market launch of the deinking system presented at K 2022 by the EREMA Group company KEYCYCLE delivering a throughput of 1,200 kilograms per hour has been a success, as has the commissioning of a further unit sold to a film manufacturer.

40 years of EREMA
The beginning of the new financial year falls almost to the day on EREMA's 40th anniversary. On 14 April 1983, Helmut Bacher, Helmuth Schulz and Georg Wendelin founded EREMA Engineering Recycling Maschinen und Anlagen GesmbH, laying the foundation for the 40-year success story. In celebration, the comapny will hold the event EREMA Discovery Day at the company headquarters on the 1st of June. This event with live insights into the latest post consumer and PET recycling technologies will also see the official opening of the newly built research and development centre.

Fibre Extrusion Technology Limited (FET) of Leeds, England, a supplier of laboratory and pilot melt spinning systems, is celebrating a record breaking year of sales and product innovation. “Sales revenue for 2022 has easily beaten our previous high” said FET Managing Director, Richard Slack “and the research projects we have collaborated in have become increasingly challenging in terms of technical specification.”

Prestigious new projects during 2022 included a multifilament melt spinning line for Senbis Polymer Innovations, Netherlands enabling the development of textile fibres from recycled polymers or biopolymers; a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research in collaboration with the renowned Henry Royce Institute; and a FET-103 Monofilament line for RHEON LABS of London to help develop a hyper viscoelastic fibre from RHEON™ which displays high strain-rate sensitive properties. The latter two of these examples were aided by significant UK grants to develop advanced materials.

FET is now looking forward to 2023 with a record order book. The company’s newly opened Fibre Development Centre features over £1.5 million investment in customer laboratory systems that will further enable fibre trials and product R&D. Three new polymer types were developed with clients in 2022 and several more are lined up in 2023, which is expected to bring the total of different polymer types to more than 40 in multifilament, monofilament and nonwoven formats.

FET will be exhibiting at two major exhibitions in 2023; INDEX 23, a leading Nonwovens show at Geneva in April; and ITMA, Milan, an international textile and garment technology exhibition in June.

The UK’s new Business Secretary, Grant Shapps has visited the Henry Royce Institute’ hub in Manchester to seal the second phase of R&D investment in the institute of £95 million. Fibre Extrusion Technology Limited (FET) of Leeds, England had previously installed its FET-200LAB wet spinning system at the University of Manchester site and this proved to be a focus for the Business Secretary’s interest, as he discussed the project with FET’s Research and Development Manager, Mark Smith.

This wet spinning technology enables fibres to be derived from sustainable wood pulp to produce high quality apparel and trials are now underway to perfect this process. FET is a world leading supplier of laboratory and pilot melt spinning systems, having successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.

During his visit, Shapps spoke of the investment programme as a means of reinforcing the UK’s standing as a leader in advanced materials research, development and innovation.

“R&D investment is a critical way to turbocharge Britain’s growth. Growing an economy fit for the future means harnessing the full potential of advanced materials, making science fiction a reality by supporting projects from regenerative medicine to robots developing new recycling capabilities, right across the country. Today’s £95 million investment will do just that, bringing together the brightest minds across our businesses and institutions to help future-proof sectors from healthcare to nuclear energy.”

The Henry Royce Institute was established in 2015 with an initial £235 million government investment through the Engineering and Physical Sciences Research Council and the latest £95 million sum represents the second phase of the investment.

Opportunities being investigated by Royce include lightweight materials and structures, biomaterials and materials designed for reuse, recycling and remanufacture. Advanced materials are critical to the UK future in various industries, such as health, transport, energy, electronics and utilities.
