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.

NatureWorks, the manufacturer of low-carbon polylactic acid (PLA) biopolymers made from renewable resources, hosted a cornerstone laying ceremony to celebrate construction of their new Ingeo™️ PLA manufacturing complex in Thailand. The ceremony which took place on February 1st, 2023 commemorated the progress made to date on the new fully integrated biopolymer facility. The day also featured a ceremonial groundbreaking that mirrored the ceremony held in Blair, Nebraska, USA in 2000 when NatureWorks began construction on the world’s first commercial scale PLA manufacturing facility.

The new manufacturing facility located on the Nakhon Sawan Biocomplex (NBC) in Nakhon Sawan Province, Thailand is designed to be fully integrated including production sites for lactic acid, lactide, and polymer. With completion expected in the second half of 2024, the manufacturing site will have an annual capacity of 75,000 tons and will produce the full portfolio of Ingeo biopolymer grades.

The expanded global production of Ingeo biopolymer will support growth in markets including 3D printing and hygiene as well as compostable coffee capsules, tea bags, flexible packaging, and food serviceware that demand sustainable, low-carbon biomaterials and require the high-performance attributes that Ingeo is uniquely suited to deliver.

“This ceremony is a meaningful milestone for the entire NatureWorks team,” said Rich Altice, president and CEO of NatureWorks. “For the last three decades, we have not only been building a company and manufacturing facilities, but also a whole new industry and market for low-carbon, renewable biomaterials that are revolutionizing the sustainability and safety of packaging and product materials used in our everyday lives.”

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.

• ESD protection in harsh environments:
• Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
• Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
• Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.

• Future plans for the nonwovens market

The two companies will develop sustainable materials solutions based on CJ Biomaterials’ PHACT™ PHA and NatureWorks’ Ingeo™ PLA technologies NTR and CJ Biomaterials

CJ Biomaterials, Inc., a division of South Korea-based CJ CheilJedang and leading producer of polyhydroxyalkanoate (PHA), and NatureWorks, an advanced materials company that is the world’s leading producer of polylactic acid (PLA), have signed a Master Collaboration Agreement (MCA) that calls for the two organizations to collaborate on the development of sustainable materials solutions based on CJ Biomaterials’ PHACT™ Biodegradable Polymers and NatureWorks’ Ingeo™ biopolymers. The companies will develop high-performance biopolymer solutions that will replace fossil-fuel based plastics in applications ranging from compostable food packaging and food serviceware to personal care, films, and other end products.

The initial focus of this joint agreement will be to develop biobased solutions that create new performance attributes for compostable rigid and flexible food packaging and food serviceware. The new solutions developed will also aim to speed up biodegradation to introduce more “after-use” options consistent with a circular economy model. The focus on compostable food packaging and serviceware will create more solutions for keeping methane-generating food scraps out of landfills, which are the third largest source of methane emissions globally, according to World Bank. Using compostable food packaging and serviceware, we can divert more food scraps to composting where they become part of a nutrient-rich, soil amendment that improves soil health through increased biodiversity and sequestered carbon content.

CJ Biomaterials and NatureWorks plan to expand their relationship beyond cooperative product development for packaging to create new applications in the films and nonwoven markets.  For these additional applications, the two companies will enter into strategic supply agreements to support development efforts.

• Collaboration between Indorama Ventures and Toyobo to meet growing global demand for airbags
• Newly completed plant in Thailand will supply high-performance nylon yarn to customers in the automotive safety sector

Indorama Ventures Public Company Limited (IVL) celebrated the completion of a plant to manufacture high-performance nylon yarn for automobile airbags. The new plant in Rayong, Thailand, was constructed by Toyobo Indorama Advanced Fibers Co., Ltd. (TIAF), a joint venture that Indorama Ventures established with Toyobo Co., Ltd in November 2020.

The plant, which has been built on the site of Indorama Polyester Industries PCL (IPI) in Rayong Province, will deliver 11,000 tons of high-performance yarn per year to meet global demand for airbags that is expected to grow by 3 percent to 4 percent annually as automakers equip vehicles with more airbags and emerging economies require cars to adopt more safety features. Test production is scheduled to start in October 2022 with the goal of starting commercial production in the middle of 2023.

In 2014, Indorama Ventures and Toyobo jointly acquired Germany’s PHP Fibers GmbH, a leading airbag yarn maker. Since then, both companies have strengthened their relationship with a focus to expand in the automotive safety sector. Mr Christopher Kenneally, based in Bangkok, leads IVL’s Fibers segment, which produces fibers and yarns across its Hygiene, Mobility and Lifestyle verticals. Mr Ashok Arora, with over 30 years of experience in fibers and polymer operations, will helm TIAF as CEO while maintaining his role as CTO with IVL Fibers.
