From the Sector

BTMA member Sellers Textile Engineers is marking its 110th anniversary this year with the introduction of a new concept in carpet shearing, as the essential final step in ensuring tuft uniformity and ‘just new’ freshness in finished carpet rolls.

The company has for many years offered two options in the construction of its shearing cylinders – the first, namely the ‘strap-on’, incorporates spiral blades bolted to the cylinder body and the second, known as the ‘caulked-in’, includes spirals which are fixed very securely in a machined groove within the machine.

The new Sellers’ Hybrid Shearing Cylinder combines the benefits of both, resulting in an improved cut and finer finish, in addition to longer repeatable finishing and increased rigidity.

“The Hybrid Shearing Cylinder has all the advantages of the ‘strap-on’ spiral blade to provide a sharper and cleaner cut, along with enhanced rigidity which significantly lengthens the intervals between the necessary regrinding of the blade,” explains Sellers Director Neil Miller. “We currently have six Hybrid Shearing Cylinders operating in the field and the earliest, which has been installed in both No1 Head position, where the majority of the shearing operation and heaviest cut is performed, and also in No3 Head, where the sharper cutting angle has resulted in a much improved surface quality.”

Sellers shearing machines have led the field in carpet finishing for many decades, enabling the leading manufacturers to stay competitive by enabling the highest quality of finish to be achieved economically and efficiently.

The latest advanced features of these machines include a load cell tension control drive system, an automated touchscreen for easy operator control and fault diagnosis, an enhanced cleaning system including cylinder and blade separation and fully controllable pivoting beds. Further options include thickness monitoring, seam detection and metal detection systems.

“The Hybrid Shearing Cylinder will become standard on our latest machines and also be made available for retrofitting, to provide significant benefits to our existing users,” says Miller. “All of our equipment is designed, manufactured, assembled and tested at our plant in the UK, and as one of the few remaining European engineering companies to make all of our components in-house – with now over a century of accumulated know-how – flexibility in design allows our finishing solutions to be targeted to specific customers and their product requirements. Aligned to this is a lead in process control systems which ensure the accurate control, reliability and repeatability of the processing parameters on all of our machines.”

Sellers remains committed to providing complete finishing solutions for all carpet, tile and artificial grass products. Its range includes machines for tufted secondary backing, both conventional, powder and extrusion lamination, Wilton and Axminster products, artificial grass and foam lines, coating lines for bitumen, PVC, PU and other polymers, as well as shearing for all carpet products.

Ongoing developments on the company’s coating and drying lines have resulted in improved guiding and product tension control as well as dryer efficiency, reducing heat loss and optimising energy use. These include a re-design of the fan pressure boxes and impingement nozzles to increase airflow efficiency, modulating gas burners and introducing easy clean, accessible filters.

In addition, the proven dual zone system has been enhanced, giving a temperature differential of up to 80°C between top and bottom zones. Dryers can be heated by either gas or steam and operation and access have been simplified with controls via touchscreen and PLC.

An extensive range of ancillary equipment is available to provide maximum flexibility to cover product requirements, for both new processing lines and as upgrades to existing equipment.

“Carpet manufacturing is now based on well-established, tried and trusted processes and it’s rare for new innovations to be introduced into this sector,” says Jason Kent, CEO of the British Textile Machinery Association. “The new Sellers Hybrid Shearing Cylinder can provide a competitive edge for manufacturers which is currently being proven in the field. It’s one of a number of new innovations the company is planning to showcase at next year’s ITMA exhibition in Milan.”

HeiQ will showcase some of its latest technologies at the Taipei Innovative Textile Application Show – TITAS 2022, from the 12th to the 14th of October, at the Taipei Nangang Exhibition Center. A newly launched, upgraded formula - HeiQ Barrier Eco Dry New, is added to the company’s fluorocarbon-free water repellent technology range and will be one of the highlights.

As urbanization and modern lifestyles cause an estimated 40% of the global population to be afflicted by allergies, HeiQ recently launched HeiQ Allergen Tech, a finish based on bio-based synbiotic technology to combat inanimate allergens on textiles. It will also be introduced at TITAS.

HeiQ innovations driving change
The global call for sustainability has put the textile industry, as the second-highest generator of CO₂ emissions, under the spotlight. Most of the marine pollution is caused by non-degradable micro-and nanoparticle emissions from washing clothes, and tons of textile items pile up in landfills. Clothing a potential 8Bn global population by 2023 doesn’t have to be a problem, and HeiQ is driving change in the textile industry so that every player can be part of the solution. In response to the ongoing energy crisis, HeiQ will emphasize the use of HeiQ Clean Tech, a polyester dyeing auxiliary system that helps mills save energy by 30-35%, thereby reducing the carbon footprint of the finished product.

The Lenzing Group and VERBUND, an energy transition company, launched the first development stage of the largest ground-mounted photovoltaic system in Upper Austria. Together with its energy partner VERBUND, Lenzing is also paving the way for the transition to zero-emission mobility. The installation of electric vehicle charging infrastructure at the company’s premises underlines Lenzing’s commitment to the energy transition process.

Thanks to the ground-mounted photovoltaic system at the “Ofenloch” landfill site, Lenzing, in conjunction with VERBUND, is consistently moving forward on the path to a carbon-free energy supply and has commissioned the first half of the new photovoltaic system with a peak power of 2,780 kWp. Full commissioning of the system with a peak power of 5,560 kWp is envisaged in mid-October. Annual electricity production will amount to 6,000,000 kWh, which is expected to cut CO₂ emissions by some 4,400 tonnes per year. The Austrian pioneer in fiber production already commissioned three rooftop photovoltaic systems in spring/summer of 2022, with a peak power of 1,454 kWp and annual electricity production of some 1,508,000 kWh. The electricity flows directly into the company’s on-site production and will also power electric charging stations in future. In the first development stage, 16 wallboxes are set to be installed by the end of the year. A further 32 charging points are planned for 2023. The charging stations will be accessible to staff, visitors and the company’s own vehicle fleet.

“VERBUND’s photovoltaic operator model allows us to make the transition to solar power without incurring investment costs or risks. Thanks to the constant expansion in renewable energy, we remain on course to ecologize the value chain, while optimizing our carbon footprint, cutting costs and reducing the load on the grid, as we are using nearly 100 percent of photovoltaic power in our production,” explains Christian Skilich, Chief Pulp Officer of the Lenzing Group.

Freudenberg Performance Materials – the Freudenberg Group’s nonwovens specialist – was hosting a meeting of the German National Hydrogen Council at the Freudenberg headquarters in Weinheim, Germany, on September 16. As a leading global supplier of technical textiles, Freudenberg Performance Materials provides fuel cell components for mobility applications and for electrolyzers used to produce CO₂-free hydrogen.

The German National Hydrogen Council was appointed by the German government and acts as an independent, non-partisan advisory board. The council board currently consists of 25 high-ranking experts in the fields of economy, science and civil society. The objective is to assist and advise the State Secretaries’ Committee on Hydrogen in the further development and implementation of Germany’s National Hydrogen Strategy. Council meetings are hosted by one of the board members to enable the council to deepen its knowledge of the relevant technologies, value chain roles and challenges. Dr. Silke Wagener is a member of the council board, and represents the Freudenberg technology group, giving input on suppliers’ know-how as well as contributing her decades-long expertise in technological solutions for the hydrogen industry.

During a tour of the factory organized for the council board members, Freudenberg Performance Materials explained the development and production of performance-critical gas diffusion layers manufactured from carbon fiber-based nonwovens for fuel cells and porous transport layers for electrolyzers. The tour highlighted the potential for improvements from a supplier’s perspective, such as the need for very timely exchange and collaboration along the value chain. Functioning, unbroken and scalable value chains, in parallel with the development and scaling of hydrogen infrastructure, are key prerequisites for the hydrogen industry to fulfill its vital role in the transformation to climate neutrality.

Gas diffusion layers are one of the main components at the heart of the fuel cell. Their function is to transport gases and liquids in the cells. They have a significant impact on system performance and costs, and are indispensable for the functioning of fuel cells. The same applies for porous transport layers that are the key component of electrolyzers for the CO₂-free production of what is called green hydrogen.

Fuel cells in combination with green hydrogen are an important technology for CO₂-free mobility, in particular with reference to buses, heavy-duty trucks and trains. Other uses include stationary applications such as stationary power generation or heat generation in buildings or industry.
Apart from mobility, green hydrogen also plays a key role in climate-neutral energy supplies in the industrial sector, particularly in the chemical and steel industries.

The Lenzing Group, a leading provider of wood-based specialty fibers, is expanding its global clean electricity portfolio by gradually transitioning to green energy at its production site in Nanjing. This will enable its Chinese subsidiary Lenzing Nanjing Fibers to use electricity derived solely from renewable sources from 2023 onwards and reduce the site’s carbon emissions by 100,000 tonnes annually. Lenzing only recently announced the transition to green electricity at its Indonesian production facility.

In 2019, Lenzing became the first fiber producer to set a target of halving its carbon emissions by 2030 and becoming climate neutral by 2050. This carbon reduction target has been recognized by the Science Based Targets Initiative. In Nanjing, Lenzing is currently investing in cutting its carbon emissions and converting a standard viscose production line to 35,000 tonnes of TENCEL™ branded modal fibers. Thanks to this move, the Chinese site will exclusively produce eco-friendly specialty fibers.

The company aims to generate more than 75 percent of its fiber revenue from the wood-based, biodegradable specialty fibers business under the TENCEL™, LENZING™, ECOVERO™ and VEOCEL™ brands by 2024. With the launch of the lyocell plant in Thailand in March 2022 and the investments in existing production sites in China and Indonesia, the share of specialty fibers in Lenzing’s fiber revenue is set to exceed the 75 percent target by a significant margin as early as 2023.

• Monomaterial solution contains renewably-sourced polypropylene from the Bornewables™ portfolio of circular polyolefins
• Trexel employs its proprietary MuCell® technology to deliver a range of lightweighting benefits
• EverMinds™ in action: reuse and design for recycling are focus of value chain collaboration

Borealis and Trexel, an expert in foaming injection and blow moulded parts, announce that they have co-developed a new plastic bottle based on a grade from the Bornewables™ portfolio of polyolefins made using renewable feedstocks derived 100% from waste and residue streams. The lightweight bottle – which will be showcased at the Borealis stand at the K 2022 (from 19 to 26 October 2022 in Düsseldorf) – is reusable and fully recyclable. It boasts a significantly lower overall CO₂ footprint because it is composed of renewably-sourced feedstock and produced in the foaming process.

The Bornewables™ portfolio of circular polyolefins helps reduce the carbon footprint while offering material performance equal to virgin polymers. Using Bornewables grades allows for design freedom and colour flexibility, and helps retain a premium look and feel. The grades – which are commercially available in Europe – help conserve natural resources because they are derived solely from waste and residue streams, for example from used cooking oil. Reusing waste already in circulation instead of fossil fuel-based feedstocks enhances the sustainability of applications made using the Bornewables grades.

The reusable new bottle developed by Borealis and Trexel retains its value over many life cycles thanks to the use of Trexel’s proprietary technology in tandem with Bornewables grades; as a material solution, the new bottle minimises the use of valuable raw materials. Moreover, converters consume less energy in the production process when using the MuCell® technology. The bottle thus helps close the loop on plastics circularity by way of design for recycling, the use of renewable feedstocks, and excellent material performance across multiple life cycles.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

Adient, a supplier of seating systems for the automotive industry, has entered into a cooperation with Swedish steelmaker H2 Green Steel (H2GS) to reduce the carbon footprint in its value chain.
 
On 1st September Michel Berthelin, Executive Vice President Adient EMEA, and Henrik Henriksson, CEO of H2 Green Steel, have mutually signed an agreement to supply fossil-free steel with low carbon footprint from 2026 on and subsequently use it in Adient's metal products.

Michel Berthelin explains the background to the cooperation: “As a company, we are committed to the Science Based Targets Initiative, a collaboration between leading global institutions to set a science-based climate target. We also support the Carbon Disclosure Project, which helps companies and cities to understand and disclose their environmental impacts. The decision to shift parts of the steel volume sourced for our production to a steel with low carbon footprint is part of our sustainability strategy. It is our goal to reduce emissions at our production sites that are caused directly by our own sources or indirectly by our energy suppliers by 75% by 2030. In parallel, we aim to reduce emissions along our supply chains by 35% over the same period. In doing so, Adient actively fosters the industry's transformation towards a more responsible use of natural resources.”

Steel from H2 Green Steel is produced with up to 95% less CO₂ emissions compared to conventional steel production. The company achieves this by replacing coal with green hydrogen in production and by the use of electricity from non-fossil sources. In this way, mainly water and heat are produced as waste products.
