From the Sector

Increasing energy and resource efficiency in the construction sector will be key to the EU’s ambition of achieving climate neutrality by 2050. By enabling the manufacture of strong, durable and lightweight products, composite materials can help the construction sector improve its environmental sustainability, as well as reduce total lifecycle costs. The latest EPTA industry briefing, Pultruded composites contribute to a more sustainable future for construction, discusses how pultruded composites answer the need for materials offering high performance, faster installation, corrosion resistance and low maintenance.

The report is available to download from the EPTA website.

The future of construction
As one of the largest global users of energy and raw materials, the construction industry is under immense pressure to improve its sustainability. At the same time, it must respond to demands for improved performance and reduced total cost of ownership. New materials will be needed to minimise the use of natural resources, enable a reduction of carbon footprint and facilitate circular economy practices. Choosing the optimum materials required for durability throughout the lifecycle will be increasingly important. A shift to off-site production is also forecast, where factory-controlled environments and automated processes can improve quality control, lower waste, and reduce work on site.

Lightweight pultruded parts can be pre-assembled into modules or complete structures in the factory for faster installation on site. Lightweight profiles lower energy use during transportation and installation, and a longer service life combined with minimal maintenance can deliver a reduced through-life carbon footprint. Pultruded parts such as profiles, gratings, beams, tubes and planks are increasingly found in a range of building, construction and infrastructure applications. Examples include bridge decks, fencing, stairs and handrails, train platforms, cladding, utility poles, modular building concepts, and window frames.

One application offering large growth potential for composites is bridges. Composite bridges are being designed to provide a service life of 100 years and unlike steel bridges do not require regular repainting to protect them from corrosion. Over recent years, pultruded glass fibre composite has become a highly popular choice for pedestrian and cycle bridges. Pre-fabricated ‘easy fit’ bridge decking planks, pre-assembled bridge modules and complete bridge ‘kits’ are now available. Corrosion-resistant composite bridges are ideal for use near water or on the coast, and in remote locations where regular maintenance operations would be difficult. A composite bridge can deliver the same performance as a steel structure with a weight saving of up to 50% or more. This enables more streamlined bridge designs which require less substantial supporting structures and foundations, greatly reducing consumption of materials and energy. Lightweight also results in easier logistics and simplified installation. Pultruded are more easily transported to the construction site, with lower fuel consumption, and easier to move on site, often reducing labour requirements and the capacity of lifting equipment.

A lifecycle approach
As the construction industry looks to the future, the environmental and economic benefits of composite materials linked to easier logistics and installation, durability and low maintenance are becoming increasingly valued. More projects are demonstrating the benefits of composite materials and standards covering the design, fabrication and installation of pultruded profiles are making it easier for the construction industry to use them. With ongoing development and collaboration, pultrusion has the potential to contribute to a more sustainable future for construction and many other industries. EPTA will continue to promote the advancement of pultrusion technology and its applications and foster sustainable practices within the industry.

INDA, the Association of the Nonwoven Fabrics Industry, was granted status last month as an accredited stakeholder with the United Nations Environment Programme (UNEP), which, among other privileges, will allow representatives from the association to observe the formal ongoing negotiations of the UN Global Plastics Treaty. INDA Government Affairs Director Wes Fisher was on site at the second session of the treaty negotiations formally titled the “second session of the Intergovernmental Negotiating Committee to develop an international legally binding instrument on plastic pollution, including in the marine environment.” The negotiations took place from 29 May to 2 June 2023 at the United Nations Educational, Scientific and Cultural Organization (UNESCO) Headquarters in Paris, France.

“We are excited to continue to enhance the capacity of INDA’s government affairs department to better serve the industry on a global scale,” stated Fisher. “We look forward to working with the UNEP to provide technical input regarding ongoing plastics treaty issues specific to the nonwovens industry, and engaging with other UN processes with our new status as an accredited stakeholder.”

Accreditation provides non-governmental organizations with observer status to the United Nations Environment Assembly, UNEP, and its subsidiaries. Accreditation will bring many advantages to INDA with respect to participation in the work of UNEP’s Governing Bodies, such as the United Nations Environment Assembly of UNEP and the Committee of Permanent Representatives.

UN Global Plastics Treaty negotiations have garnered significant attention from both industry and environmental groups. At least three more negotiation sessions are expected with the goal of finalizing a treaty by the end of 2024.

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

Freudenberg Performance Materials Apparel (Freudenberg) launches its biodegradable fusible cotton shirt interlinings range 46xx. With this innovation, the world’s leading specialist in woven, knitted, weft and nonwoven interlinings reduces its impact on the environment and supports customers in achieving their own sustainability objectives. In Asia, the series is marketed under the name 42xx series.

Approved biodegradability and non-toxicity by Hohenstein Laboratories
The new Freudenberg fusible interlinings for shirts and blouses have been developed in such a way that they are harmless to people and the environment at the end of their life cycle. Germany’s independent Hohenstein Laboratories performed biodegradation tests on the 46xx series, based on the Hohenstein method which draws on DIN EN ISO 11721-2:2003 and EN ISO 846, and approved it as biodegradable and ecotoxicologically harmless. The tests by Hohenstein showed no negative effects on either the germination of garden cress nor on earthworms in the acute toxicity test.

Energy-saving interlining
The new biodegradable shirt interlinings also show great potential for energy saving, as the fusing can be performed at a low temperature. Concretely, this means that the resulting temperature between the upper fabric and the shirt interlining during fusing is only 127°C which is significantly lower than the commonly used temperature of 143°C. Certified to OEKO-TEX® STANDARD 100 Class II for successfully testing for no harmful substances, the shirt interlinings are washable at up to 40°C and resistant to dry cleaning. In addition, it has also passed all ecological-toxicological tests and is a perfect end-of-life cycle solution.

Product details and availability
The products in range 46xx are available in Europe in the color white and the following weight classes: 4605 (90g/m2), 4616 (150g/m2) and 4618 (55g/m2). The adhesive of the interlinings consists of a 100% degradable bio-polymer. The shirt interlinings are ideal for reinforcing shirt and blouse collars, cuffs and plackets used in fashion, leisure and business clothing. The biodegradable, non-toxic interlinings are particularly important for labels with an ecologically sustainable claim.

A little over three years have passed since RadiciGroup announced the acquisition of Zeta Polimeri, an Italian company headquartered in Buronzo (VC) with over 30 years' experience in the recovery of pre- and post-consumer synthetic fibres and thermoplastic materials. Today, the company has become a full member of the Group with its new name Radici EcoMaterials Srl.

The new company’s long-standing know-how, combined with RadiciGroup’s as a whole, will create a virtuous production system that recovers worn-out materials (fabric, yarn and granules), or otherwise unusable materials, and processes them into raw materials available for other production cycles by taking advantage of industrial synergy.

Radici EcoMaterials is a strategic production site because it handles all the preliminary recovery stages: the sorting, processing and pre-treatment of materials, including those used for the production of post-consumer yarns and engineering polymers. In this sense, Radici EcoMaterials is in line with the most recent European policies on sustainable textiles, which address minimizing the share of materials destined for disposal sites, favouring instead more structured recycling solutions.

Radici EcoMaterials is also GRS certified. GRS certification ensures the complete traceability of its materials, which are made in a safe plant that meets the highest environmental and social certification standards.

The company is also equipped with a photovoltaic system and, for the portion of its energy needs not covered by the photovoltaic source, it partially relies on renewable energy. The goal is to use 100% green energy in the next few years, in accord with RadiciGroup's goals.

The Woolmark Company, the Italian wool fabric mill Vitale Barberis Canonico (VBC) and Haelixa took part in a trial to trace Australian wool fibers up to the final fabric.

Funded by Australian woolgrowers, The Woolmark Company (TWC) is an enterprise that focuses on investments that enhance the profitability, international competitiveness, and sustainability of Australian wool. In their operations, TWC seeks to be transparent and accountable. In line with this strategy, traceability is necessary to ensure transparency and maintain the credibility of TWC.

In December 2021, Haelixa marked wool fibers with their DNA tracing solution. There are infinite DNA markers that could be produced and used to indicate a specific origin, supply chain, material, or particular collection. In this case, a single DNA has been applied to greasy wool and a second DNA marker to scoured wool. The first DNA identifies the origin of the Australian wool, while the second determines the manufacturer where the wool has been further processed; at Vitale Barberis Canonico mill.

Samples were collected from various production stages, where a qPCR test was used to detect each specific DNA marker. Haelixa uses a “Key-Lock” system to detect a marker; one needs to know the particular DNA to screen for, ensuring that the system is tamper-proof. The DNA markers stay safely embedded in the product, enabling traceability of greasy and scoured wool up to greige fabric and finished fabric, respectively.

With increasing cost pressure and competition in the wool fabric market, traceability is becoming a prerequisite to proving authenticity and origin. TWC and Vitale Barberis Canonico support the culture of sustainability and collaboration.
