From the Sector

Beaulieu International Group will turn the spotlight on geotextile products with sustainability benefits to support progress in resilient civil engineering projects at the 12^th ICG Rome from 18^th -21^st September 2023, presenting options to target fossil carbon reduction by choosing PP-based staple fibres or woven geotextiles that are among the lowest in carbon footprint for geosynthetics.

For manufacturers of nonwoven geotextiles, Beaulieu Fibres International (BFI) offers PP fibres with > 25% carbon footprint reduction compared to the European standard PP fibres, generating 1.48 kg CO₂/kg PP fibres. A step further is to accelerate the replacement of fossil carbon in engineered fibre applications by choosing its ISCC Plus certified bio-attributed MONO-PP with a negative carbon footprint.

For construction projects, nonwoven geotextiles made with high-tenacity HT8 fibres are proven to secure a longer service lifetime and reduce the environmental impact, as they offer high mechanical performance at a reduced weight.

Beaulieu Technical Textiles' (BTT) woven geotextiles provide a wide range of functions, including separation, filtration, reinforcement and erosion control, and are among the most sustainable in the industry. Depending on weight, the carbon footprint of its woven geotextiles (m²) ranges between 0.37 and 1.40 kg CO₂ eq./m². They also minimize the use of natural resources for more sustainable infrastructure development. Case studies such as at the Ostend-Bruges airport highlight significant CO2 reduction on the jobsite by replacing the transport of 960 trucks of gravel with 3 trucks of woven geotextiles, and by extending the runway’s life span.

The ICG launch of its new line Terralys MF woven filtration geotextiles with monofilament boosts the performance of a common solution in building layers that require high water flow rates. High-tenacity extruded polypropylene tapes and monofilaments are interwoven to form dimensionally stable and highly permeable geotextiles. These new filtration geotextiles provide greater resistance to dirt and biological clogging. They allow water to travel freely while reducing soil erosion when employed as a separation and stabilizing layer.

As of September 2023, all PP staple fibres and woven geotextiles will have Environmental Product Declarations (EPD) based on LCAs. Each EPD is an essential tool for communicating and reporting on the sustainability performance and helps carbon-conscious customers in their purchasing and decision making. Registered EPDs are globally recognized, publicly available and free to download through EPD Libraries.

The Gleaming line by the Marchi & Fildi Group includes a wide range of metalloplastic yarns for the most varied of uses. Reflex, the new range of reflective yarns, will join the line.

In addition to uses in the worlds of fashion and furnishings, for fancy yarns, decoration and accessories, an important application for the Gleaming collection is in the sector of technical clothing with high-visibility features.

Reflex, used for the production of fabrics and tapes, able to reflect the light and ensure good visibility for people wearing them in low-light situations, is augmented by new colour shades in addition to the traditional greys.

The innovative reflective yarns in white, black, and light and dark multicolours offer new possibilities for:

• tapes, external labels and accessories;
• technical fabrics for work clothing with specific safety standards;
• uniforms, sports clothing and accessories;
• hosiery, gloves, bibs and hats for night use, for winter clothing and for northern markets.

The latest addition to the range, with an important functionality, is the Reflex stretch yarn, which, apart from in the sectors described above, also finds application in flat bed or circular knitting and sewing. Its composition makes it softer and more versatile in comparison to traditional reflectives.

The Gleaming line represents a completion of the range of yarns produced by the Marchi & Fildi Group. The yarns are available in various thicknesses, widths and types in both metallised and transparent versions, and iridescent, reflective and phosphorescent effects. Also articles are included with particular features of resistance to chemical and dyeing treatments.

Amongst the most recent innovations is the line of metalloplastic yarns in 100% polyester obtained from post-consumer recycling with GRS (Global Recycle Standard) certification.

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.
