From the Sector

• DiloGroup looks forward to participating in the Techtextil India show 2021.

DiloGroup offers tailor-made production systems from one supplier and will inform at this forum in the German pavillon about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts.

The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products. The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

With more than 370 installations delivered to the nonwovens industry worldwide, DiloGroup has the necessary know-how and the complete equipment portfolio to engineer the perfect production line for any product specification. The efficiency of Dilo production lines is the result of long-term research work and experience. Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.

Depending on the application and task, different measuring methods are used for this purpose.

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

Hexcel has collaborated with HP Composites S.p.A (HP Composites), a world leader in the production of carbon fiber components for automotive and motorsports, to develop carbon fiber Class A body panels. Hexcel HexPly® XF surfacing technology is being extensively used by the Italian component producer to manufacture external body panels and other components for supercars such as Alfa Romeo’s stunning new supersport sedans, the Giulia GTA, and GTAm.

With five production plants in Italy, HP Composites has built an impressive track record of high-performance composite successes on both road and racetrack. HP has combined this processing expertise with Hexcel HexPly® XF3 surfacing material, HexPly® M47, and HexPly® M49 prepregs, working to the highest standards set by the most prestigious supercar OEMs and leading motorsport teams.

Hexcel’s automotive composites portfolio is the result of decades of industry experience and the creation of strategic partnerships to develop and optimize leading-edge technologies. HexPly XF3 is an epoxy prepreg surface material, developed with processing input from the HP Composites team to address the challenges of producing high-quality Class A automotive body panel surfaces with excellent resistance to aging tests.

Applied as the first ply in the mold and after curing at 120-180˚C in an autoclave, HexPly XF3 produces a smooth part surface with no porosity, that requires minimal preparation for painting.

HexPly XF3 is supplied in an easy-to-handle roll format with good tack and drapability. After curing, it can be easily prepared for painting with a rapid sanding process. HP Composites has incorporated automated robotic sanding techniques for this finishing stage with the paint-ready HexPly XF3 surface providing excellent paint adhesion according to EN ISO 2409.

HP Composites typically uses autoclave processing for HexPly XF3 parts, maximizing weight savings and structural performance of the final components. In addition, HP has also developed its own proprietary press and compression molding processes, including Air Press Moulding® technology, compatible with HexPly XF3 and other HexPly prepregs for higher volume production series that require increased production rates.

“Our long-term experience has given us a detailed understanding of the critical features that influence how prepregs and surfacing technologies interact with different production processes,” said Abramo Levato, General Manager, HP Composites S.p.A. “The relationship we have with Hexcel is both highly technical and highly supportive. As a result we have a complete material package for high-quality Class A body panels that are formulated specifically with our requirements in mind.”

“Combining the expertise of HP with a strong technical interaction and collaborative dialogue, Hexcel and HP were together able to develop the optimum HexPly XF surfacing technology,” said Claude Despierres, VP Sales and Marketing, Hexcel. “With HexPly XF3 we satisfy the toughest industry standards.”

• Harmonized Language Increases Efficiency to Communicate Globally Consistent Descriptions, Production and Testing

EDANA and INDA, the leading global nonwovens associations, jointly announce the launch of the 2021 edition of standard procedures for the nonwovens and related industries.

These Nonwovens Standard Procedures help technically define the nonwovens industry, with specifiers for the properties, composition, and specifications of its products. Offering harmonized language for the industry across the USA and Europe, and recognized by many other individual markets, the procedures offer a way for the nonwovens industry to communicate both across the globe, and within the supply chain to ensure that product properties can be consistently described, produced, and tested.

The harmonized methods contained in the Nonwovens Standard Procedures (NWSP) edition include 107 individual test procedures and guidance documents to support applications across the nonwovens and related industries, and are available on both www.inda.org and www.edana.org.

The 2021 edition includes updated or modified procedures with a numbering structure that makes the document intuitive to search and use. Additionally, each method also includes a page to summarize and track relevant changes made to the document. In an effort to make all methods more consistent, each one is now presented in a format building on the International Standards Organisation (ISO) template, facilitating any future possible submission to ISO in an effort to become a recognized international standard or technical specification.

As in previous editions, the table of contents for the Nonwoven Standard Procedures document includes references to existing related ISO standards, which makes it easier for technicians to choose the most relevant procedure or methods to apply to their product.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.
