From the Sector

SABIC has announced that the newly formed Hygiene & Healthcare segment of its Petrochemicals business will showcase its extensive portfolio of SABIC PURECARES™ polypropylene (PP) and polyethylene (PE) polymers for high-purity nonwovens and hygiene films at the upcoming INDEX™ Expo in Geneva, Switzerland, from October 19 through 22, 2021. The company will also present enabling solutions developed with partners to address the issue of plastic waste and support the transformation of the industry towards a circular economy with closed-loop initiatives and certified circular polymers under its TRUCIRCLE™ portfolio and services.

During INDEX, SABIC will exhibit a wide range of PP polymers targeted at these needs. Highlights on display will include dedicated PP and PE grades for lightweight nonwoven fabrics using the latest spunbond and meltblown processes, and a new ultra-high melt flow PP product engineered for meltblown fibers in nonwoven fabrics. The nonwoven focus will be complemented by industry proven polyolefins for cast and blown film applications in hygiene webs and laminates, providing desirable back and top sheet properties such as water tightness, breathability and elasticity.

In addition, SABIC will also present ISCC Plus certified fiber and film polymers based on circular and renewable PP and PE polymer technology as part of the company’s TRUCIRCLE portfolio for advancing the transformation of the plastics industry from a linear to a truly circular economy. Examples of this comprehensive initiative include collaborations with various market leaders in the field. Together with Fibertex Personal Care, one of the world’s largest manufacturers of spunbond nonwovens for the hygiene industry, SABIC is creating a range of high-purity nonwovens for the hygiene market using ISCC PLUS certified circular PP polymer derived from post-consumer plastic waste. In another project, Fraunhofer Institute, SABIC and Procter & Gamble (P&G) joined forces to develop and demonstrate the feasibility of an advanced close-loop recycling process for used nonwoven facemasks.

• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer enterprise development teams and individually for the respective projects." This is how novel and unique lightweight components made of high-performance textiles are created for visionary projects.

Hexcel, a global leader in advanced composites technologies, announces the successful maiden flight of a lightweight camera drone, developed using Hexcel HexPly® carbon fiber prepregs. The composite drone was developed by a team of students from the University of Applied Sciences Upper Austria in Wels with composite materials supplied by Hexcel Neumarkt in Austria.

A team of six students in the university’s lightweight construction and composite materials course was responsible for the complete design, engineering, and manufacture of the camera drone over a period of 18 months. Hexcel materials and optimization of the composite engineering enabled the team to reduce the composite structural mass by an impressive 42% compared to similar drones.

Hexcel Neumarkt was one of eight industrial partners supporting the university team throughout the project, providing all carbon fiber prepreg materials used for the drone’s landing gear as well as the fuselage. The ultra-lightweight 32g landing gear was laid up and cured in the press, whereas the fuselage was autoclave cured by the student team using Hexcel HexPly M901 and HexPly M78.1 prepreg resin systems with a combination of woven and unidirectional carbon fiber reinforcements.

With the development of Unmanned Aerial Vehicles (UAV) as a key emerging market and innovation space in the transportation sector, Hexcel’s collaboration with the University of Applied Sciences Upper Austria team not only creates an important link with the next generation of lightweight composite engineers but also highlights the weight saving and structural benefits of Hexcel composite material solutions.

"The massive weight saving achieved with their updated version of the camera drone is a fantastic achievement by the student team," said Michael Rabl, Dean of FH Wels of the Upper Austria University of Applied Sciences. "The joint study not only illustrates the wide range of complex and innovative composite techniques present in the drone sector but also presents the opportunities that exist for further development in the wider Urban Air Mobility (UAM) and aerospace composites markets.”

Hexcel congratulates the project team which includes Lukas Weninger, Karl-Heinz Schneider, Jakob Schlosser, Matthias Thon, Marla Unter, and Simone Hartl on an exceptional piece of lightweight composite design and thanks them for showcasing the contribution of Hexcel materials with a presentation and drone flight. Johanna Arndt, research and technology group leader at Hexcel Neumarkt, said, “It was a great pleasure to work with the team who were very cooperative and self-motivated to succeed. Watching the drone just fly around the Neumarkt plant was just great.”

Hexcel manufactures a complete range of carbon fibers, dry carbon UD tapes, specialty reinforcements, prepregs, and honeycomb core materials, providing customized manufacturing options for new UAM applications that combine aerospace reliability with the high-rate production required. Hexcel composite materials are the ideal solution for the lightest and most efficient cost-competitive transportation vehicles of the future.

Contact restrictions, home office and altered daily lives – our lives in 2020 were radically changed. This was also the case for various sectors of the economy, including the textile and clothing industry. However, with crisis come opportunities and stimuli for change. Under the motto “Still Physical”, manufacturers recount their personal success stories in 2020 – the industry can look forward to a selection of sustainable materials curated exclusively by the PERFORMANCE FORUM Jury. Areas of focus: natural fibers that highlight wellbeing aspects, plant-based materials that make us strong and excite on an emotional level, bio-nylons and bio-based finishings that rethink function. “Still Physical – Your Success Story of 2020” will be on display online as the first of its kind within a trade fair week from 17 to 21 May 2020.

Transformation: Technology first?
The pandemic has forced us into new, primarily digital forms of living and working. Our daily lives are characterised by home offices, home schooling and online meetings. The desire for real, physically perceptible experiences has grown incessantly within the last year. In the same context, people nowadays are strongly driven by technological progress – yet how far can we allow technological change to go and how do we wish to live in the future? Long before the pandemic, the trend towards self-monitoring and control of important bodily functions developed. The sports industry developed tools to measure levels of performance and monitor bodily functions with the goal of enhancing performance. Self-optimisation, body shaping and health promotion have become standard nowadays. Staying healthy and keeping fit are now social imperatives in our performance-oriented society. The pandemic has made us rethink, made us pause – with sustainable function still in focus, yet function needs to be rethought for the future, distancing ourselves from mere performance enhancement, and embracing clothing that facilitates people in feeling good.

Touch & Feel
In a visual, digital world, one sense has been forgotten: the sense of touch. Materials trigger completely different reactions, consciously or unconsciously. Moreover, the surface texture is also decisive in the functionality of a fabric, lending it its unique characteristics. In times of contact restrictions and lockdown, there is a need for a space for emotions, for regeneration and physical wellbeing. This is also reflected in the desire for appropriate apparel that leaves a pleasant sensation on the skin. Lightweight, warm and of a softer nature, plant-based fibers fulfil the desire for comfort and promote wellbeing.

We are physical – we are nature
How will we shape and adapt the post-pandemic textile and apparel industry? The Corona crisis once again reminds us of our existential bond with the natural world. While humanity fights against the spread of a deadly virus with social isolation, one thing is doing well: our planet. It is recovering from all the exhaust gases that are released into the air daily by cars and factories. There is a shift in focus towards taking time out in nature, whether in the form of a morning run, a mountain hike or a yoga session on the grass.

Your success story of 2020
What has touched them? Which experiences have shaped their latest innovations? Does the crisis also present opportunities? The chance for something new, for a rethink, on an even more sustainable, more ecological path? Which highlights, which stories are worth communicating and where did the focus lie in 2020? Various material manufacturers already started to focus on sustainability and the cautious use of resources some time ago. Innovations in the areas of materials and in processing methods are the driving forces of the development towards more sustainability. However, we need to realign all processes and structures in our supply and production chains and adapt them to the needs of a resource-conserving, responsible industry. A pioneering example of such alignment was the decision of PERFORMANCE DAYS to only present sustainable materials at the PERFORMANCE FORUM from the November 2019 trade fair event onwards. Additionally, the setting-up of the new digital sourcing platform “THE LOOP” shows how technology can be implemented aside from material and processing innovations in such a way that our procedures and structures can be adapted to difficult conditions.

Informative & up-to-date: the digital trade fair week from 17 to 21 May 2021
As usual, the highlighted fabrics from the Focus Topic “Still Physical”, which the exhibitors have defined as their personal success stories, will be available shortly on the PERFORMANCE DAYS website highlighting all details and facets.
