Technology transfer that is creating waves

For more than a decade now, the Manmade Fibers segment of the Swiss Oerlikon Group has been hosting a comprehensive technology symposium at the beginning of each year in the Indian region around Silvassa/Daman. Numerous Indian manmade fiber producers have settled in this area, around a four-hour drive north of Mumbai. Fed from Oerlikon polycondensation and extrusion systems, these companies manufacture polyester, nylon and polypropylene on large-scale installations with Oerlikon Barmag WINGS POY, WINGS FDY, IDY and DTY product lines and using Oerlikon Neumag’s staple fiber and BCF technologies. Reason enough for the Manmade Fibers segment’s experts to regularly provide their clientèle with detailed specialist presentations in India on the latest developments of the product and service portfolio.

And this was once again the case at the event held at the beginning of 2020, where around 450 managers and employees from local businesses took the opportunity to exchange ideas and information. For the third time in succession, Oerlikon also entered into dialog with the next generation of managers at major Indian polyester and nylon manufacturers in a separate event hosted in Mumbai beforehand. The technology symposium was again held – for the very first time – just a few days later and in a slightly modified form at a second venue: in Kolkata in West Bengal, a potential second future key location for manufacturing manmade fibers in India according to plans revealed by the Indian government. Here, the discussions held by the Oerlikon experts focused above all on the transfer of technologies for manufacturing polyester, nylon and polypropylene. Oerlikon is able to offer the entire process chain – from the melt to the textured yarn or the fibers and including the necessary semi- and fullyautomated logistics process – from a single source. This is of interest above all for potential new customers and investors in West Bengal and neighboring Bangladesh, as some do not have decades of expertise in manufacturing manmade fibers, as is the case for most companies in the region around Silvassa/Daman.

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

A new non-halogenated FR compound called PAL...VersaCHARTM can achieve a new level of flame retardant performance as a coating for nonwovens and technical textiles.

PAL...VersaCHARTM has been tested to 1,950°C – the highest to date – and shown to prevent all flaming drips of polymer. Char bodies form on the compound surface, protecting against flame creation and delaying heat transfer. Rapid self- extinguishing burn behaviour protects any underlying substrate to which it is adhered.

The compound has passed ASTM E84 (Class A) with a 15/10 rating, which includes ‘clean’ smoke generation of only 2.3% of the allowable ASTM smoke limits. In addition, the compound is light weight, at a specific gravity of 1.0, and 100% non-toxic in every respect, being free from heavy metals, halogens and VOCs. 

Other properties include excellent cold crack performance, hydrophobicity, printability, extreme chemical resistance and the ability to be custom tailored for specific needs such as UV or antimicrobial performance, as volume warrants. The compound is also very competitively priced.

In addition to its use as a coating, PAL...VersaCHARTM compound can be produced as a flexible film or sheet and moulded to shape or over-moulded to most materials, including metal for corrosion resistance. As a polymeric compound it can be cast or calendered and typical durometers from 80-99A for flexible-to-high rigid formats are practical. 

Separately, an adhesive has been created which bonds to many surfaces. In internal evaluations of two laminated plies of woven carbon fibre and two plies of glass fabrics, both passed a 60 second vertical burn with no ply separation, distortion or flaming drips from the adhesive.

Dynamic Modifiers envisages many uses for PAL...VersaCHARTM, from aerospace to the protection of rigid structural materials in building interiors etc.   
 

At JEC World 2020, MECELEC COMPOSITES is a finalist of the JEC Innovation Awards in the Design & Furniture category. The Group announces the launch of a new sustainable development application on the urban design market. MECELEC COMPOSITES designed the first mass-produced flax fibre roofs for the 550 Morris columns installed by JCDecaux in Paris. “This is the first application of flax fibre BMC for mass production. The new solution combines all the advantages of composite materials, lightness and strength, with stringent environmental requirements and is adapted to the safety constraints of this kind of street furniture,” says Bénédicte Durand, Chief Executive Officer at MECELEC COMPOSITES.

A COMPOSITE ROOF THAT IS BOTH INNOVATIVE AND GREEN
The dome of the Morris columns is composed of 23 different parts, 14 of which are made from composite materials. To design the roof, MECELEC COMPOSITES developed a new RTM complex and a new BMC material, that is reinforced exclusively with a flax mat. “Today it is the only BMC with a 100% flax fibre reinforcement, which uses a partially recycled ABS resin. It was created specifically for this project and we had to work on the processes in order to adapt them to this new material,” explains Bertrand Vieille, Head of sales.
In the design, MECELEC COMPOSITES replaced the bonding process with a time-saving mechanical assembly process using an invisible fixing system.

AN ECO-FRIENDLY APPLICATION IN LINE WITH THE GROUP’S ECO-DESIGN CSR APPROACH
MECELEC COMPOSITES creates scalable, sustainable and environmentally-friendly street furniture. The Group is committed to developing a sustainable production process and reuses all its waste materials. MECELEC COMPOSITES R&D laboratory promotes eco-design with a process of characterisation and mechanical sizing of parts. “For this project, we imagined, created, produced and delivered a mass-produced composite application with a low environmental impact within less than a year. At the end of its lifecycle, the product completely breaks down, leaving no fibre residue,” Bénédicte Durand concludes.

The Oerlikon Manmade Fibers segment will be presenting itself at the Egy Stitch & Tex 2020 between March 5 and 8, 2020 in Cairo – with a clear focus on the needs of the African market. In Hall 1, Stand B2 The Oerlikon Barmag and Oerlikon Neumag experts will also be showcasing the comprehensive product and service portfolio of the world market leader for manmade fiber systems at the stand of Oerlikon’s representative ATAG Export & Import.

The spotlight of the Oerlikon Manmade Fibers segment’s trade fair attendance will be on two core technologies: the new generation of Oerlikon Barmag eAFK Evo texturing machines is to be unveiled within the African market for the very first time. It promises higher speeds and productivity with consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. In particular, the numerous value-added features include two that convince with cutting-edge technology: the optimized, innovative EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

The second technology focus offers new opportunities for the Egyptian market and the Middle Eastern markets in particular: with Oerlikon Neumag’s BCF S8 monocolor and tricolor system, the segment will be unveiling its new carpet yarn production flagship. Superlative spinning speeds, up to 700 individual filaments, finer titers of up to 2.5 dpf – the performance data and technological finesse of the new system have already made a huge impression at numerous trade fairs and roadshows over the past year. The tricolor’s core component is the new, patent-pending Color Pop Compacting unit (CPC-T) for even more flexible and more even color separation. With the CPC-T, individually-controllable air pressures for each color provide pre-tangling, which accentuates the colors and hence makes more than 200,000 different shades possible. Whereas it has been very difficult to manufacture strongly color-separated or color-accentuated BCF yarns from polyamide 6 to date, this will in future be possible thanks to the CPC-T system. As a result of the new design, the CPC-T is now also suitable for processes with low yarn tensions.
 
Expanded product offering for manufacturing carpet yarns
Know-how covering all relevant technologies deployed in manmade fiber spinning plants enables Oerlikon – as the world’s only manufacturer – to expand its range of products and services for making carpet yarns. The POY- and texturing-based system concept is designed for a carpet and home textiles segment that demands particularly soft and bulky polyester yarns with BCF-like properties. Here, the aim is to produce yarns with titers of max. 1300dtex and typically more than 1,000 filaments, with typical products including, for example, 1300dtex f1152, 660dtex f1152 and 990dtex f768. The machine concept comprises the well-known WINGS HD POY winder, along with the eAFK Big-V texturing machine.
