From the Sector

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

Haelixa, the Swiss traceability company and Damteks Textiles have announced a collaboration to mark and trace recycled acrylic fiber. Damteks is offering their recycled yarn to customers whereby they are able to place an order with the unique Haelixa DNA already attached.

The Haelixa solution is DNA markers which are solved in liquid and applied to fibers as a fine spray. Spot checks are completed after spraying to determine the presence of DNA and identify the product. The test is based on PCR technology that is 100% reliable and has forensic validity.

Damteks saw an increase in demand for blended yarn in the last year. The request is most often a composition of 30% recycled fiber with 70% standard fiber. Brands are looking for options to be more sustainable and Damteks proactively sought out an answer. They are offering the yarn with Haelixa DNA to validate the recycled acrylic in the mix.

The haelixa team visited the Damteks recycling facility in Istanbul to kick off the partnership that will continue throughout 2023. The traceability program has the DNA sprayed on the recycled fibers before spinning. The project also saw the use of a tailored Haelixa liquid sprayer designed by the team based in Switzerland. When manufacturers do not have built-in moisturizing systems, Haelixa provides them with a custom unit to shower the DNA liquid onto the fibers. This sprayer is engineered to match the mechanical processing of the customer.

Damteks is a family-owned business that pride itself in carefully selecting environmentally responsible options for its production processes. On top of the certifications they have obtained including - GRS, RCS, GOTS, OCS - Damteks decided to have their products "Marked and Traced by Haelixa" to add additional credibility and reliability. Damteks plans to offer marked and traced by Haelixa yarn in different dyes as their offering to brands.

Belgian textile innovator Devan Chemicals will launch Purissimo® NTL, a biobased and readily biodegradable allergen control technology, at the upcoming Heimtextil trade show in Frankfurt (January 10-13, 2023). It is based on probiotic encapsulation technology and can be applied to textiles during the finishing stage of the textile manufacturing process. Purissimo® NTL cleans up pet dander, pollen and house dust mite allergens in textiles throughout the home.

Purissimo® NTL is based on Devan’s already well-established probiotics, incorporated into a new microcapsule shell. The shell is based on a natural crosslinked biobased polymer, which results in microcapsules that are up to 97% biobased and readily biodegradable (OECD 301B).

Firstly, dormant probiotic bacteria (spores) are encapsulated. The microcapsule product is then integrated into textiles. Friction opens the capsules and releases the spores. The spores absorb humidity, self-activate and start to multiply. The probiotic bacteria start to consume the allergens that cause allergic reactions and asthma. Due to lower allergen concentration, individuals with respiratory allergies such as house dust mite matter, pet allergens and pollen allergens will have milder to no symptoms and hence a better well-being feeling.

Purissimo® NTL can be used on a wide range of textiles such as mattresses, pillows, bedcovers, blankets but also upholstered furniture, carpets, curtains and public transportation and pet items, such as bedding. It is Oeko-tex® compliant, has a long-lasting effect and a wash durability up to 30 washes is achievable.

December 29, Renewcell dispatched the first shipment of Circulose® dissolving pulp produced at its Renewcell 1 plant in Sundsvall to a customer. This sale is the latest step in the ramp-up of Renewcell 1 to its initial capacity of 60,000 tonnes per year.

Founded by innovators from Stockholm’s KTH Royal Institute of Technology in 2012, Re:NewCell AB (publ) (‘Renewcell’) is a multi-award-winning sustaintech company based in Sweden. The company’s vision is to make fashion circular. Through its patented process, Renewcell is able to recycle cellulosic textile waste, such as worn-out cotton clothes and production scraps, transforming it into a pristine new material called Circulose®.

Valérius 360 wanted to make a sustainable, circular approach possible in the fashion industry. Working together with Trützschler, a collaborative project has now achieved high-quality recycled yarn – opening up massive potential to drive measurable progress toward a circular and sustainable textile industry.

Testing at the Trützschler Technical Center
The team from Valérius 360 wanted to find ways of improving the processes for yarns made from 50 % recycled and 50 % virgin cotton (Ne30). In particular, it was seeking ways to reduce thick and thin spots, which disturb the appearance of the textile surface.

At the Trützschler Technical Center in Mönchengladbach, they conducted special trials that showed that using a direct spinning process for this application delivers much better results than a process with a draw frame passage for rotor yarns.

In direct spinning, the sliver from the card is directly drawn in the draw frame which is integrated in the can stock. This involves one less process step than using an autoleveller draw frame, while also saving space and giving staff more time for other operations.

On-site support from Trützschler Customer Service
The team from Valérius 360 also received in-house training from the Trützschler Customer Service department. Together, they analyzed and significantly improved the process at the Valérius 360 production site. This helped to bring yarns made from recycled raw materials up to the required level of the 50% Usterstatistics. This is the reference level for yarns made from virgin raw materials. Accordingly, 50 % of all yarn producers with raw cotton for rotor yarns and comparable yarn counts produce a poorer quality.

Society and the economy are facing existential challenges. In addition to the consequences of climate change, these include the realisation that energy and many resources are no longer available in the usual quantities, so that their efficiency must be significantly increased in the short term. Lightweight construction, especially with fibre composite materials, can and will make an important contribution here, e.g. in wind power plants or hydrogen storage systems. As an umbrella organisation, Composites Germany represents the capabilities and interests of the German fibre composite industry. With the re-entry of Composites United, Composites Germany will combine the forces of the two leading composites networks in Germany and its position will be significantly strengthened. Changed framework conditions make the re-entry possible and necessary.

VDMA and Leichtbau BW will continue to support the work of Composites Germany as associate members and contribute the know-how of their members. Together, the organisations will promote sustainable lightweight construction as a key technology for Germany, focusing on composites materials, says Prof. Klaus Drechsler of Composites United, one of the two board members of Composites Germany. As a network and mouthpiece of the composites industry, Composites Germany bundles the interests of its members. The aim is to continuously expand activities, promote innovations and technologies, develop new markets and new value chains, and anchor training and further education, adds his board colleague Dr Michael Effing of AVK. The agreement was concluded on 29 November 2022 during the JEC Forum DACH in Augsburg, where both associations were cooperation partners of the event.

Die MUNICH FABRIC START ist in Deutschland eine führende Messe für zukunftsrelevante Textilinnovationen für den Fashionbereich. Ob auf der integriert stattfindenden internationalen Denim Tradeshow BLUEZONE oder in den Areas Fabrics und Additionals mit Materialneuheiten für alle Bekleidungssegmente, ReSOURCE und Sustainable Innovations für nachhaltige Denkansätze, Design Studios mit Stoffdesigns und neuen Entwicklungen für Prints, dem Innovationshub KEYHOUSE oder im neuen Sourcing-Areal THE SOURCE für internationale, vertikale Integration – nachhaltige Entwicklungen ziehen sich durch alle Bereiche. Dazu gehören:

Tee-Textilien
WASTEA by SCAYS: Von Schuhen, über Gürtel und Taschen bis hin zu Flugzeugen oder Yachten – in all diesen Bereichen könnte in Zukunft eine neue pflanzenbasierten Lederalternative zum Einsatz kommen: WASTEA. Nach der Einführung von Apfelleder hat die Unternehmensgruppe mit Sitz in Istanbul, SCAYS, auf der vergangenen Edition der MUNICH FABRIC START seine neueste Entwicklung präsentiert: Leder aus Teeabfällen. WASTEA basiert auf zwei Komponenten – einem Textil als Basis und einer Beschichtung aus dem neuen Tee-Material. Für ein späteres Recycling könnten die Schichten voneinander getrennt werden, so SCAYS. Aus dem Textil werden wieder Textilien, aus WASTEA wird WASMENT – eine neue Art Zement, aus dem das Unternehmen in der nahen Zukunft Schulen bauen möchte.

Blumenleder
Flower Matter by Irene Purasachit: Täglich entstehen Unmengen an Blumenabfällen – die in Finnland lebende Designerin Irene Purasachit schenkt ihnen ein zweites Leben. Blumenstiele und -blätter recycelt sie zu Stoff und Papier – eine vegane Alternative zur Herstellung von Taschen, Geldbeuteln oder Blumenpapier. Da das sogenannte „Flaux“ Material zu 100 Prozent aus Blumenresten besteht, ist es komplett natürlich, biologisch abbaubar, plastik- und lederfrei.

Bakterielle Zellulose
Biotic by Studio Lionne van Deursen: Man nehme Hefe, Bakterien und gesüßten grünen Tee – nach einem Fermentationsprozess wird daraus biologisch abbaubares, widerstandsfähiges und hochflexibles Material. Wie das funktioniert? Mikroben spinnen Nanofasern aus bakterieller Zellulose auf eine Oberfläche. Sobald diese Schicht getrocknet ist, wird sie zu einem festen Material, das sich in den Eigenschaften sehr ähnlich zu Leder verhält. In Experimenten mit Pflanzenfarben und Farbstoffen aus Fruchtabfällen hat die gleichnamige Designerin des Studios für Materialforschung und Produktdesign „Lionne van Deursen“ aus den Niederlanden eine Stoffkollektion in bunten Farben, mit unterschiedlicher Lichtdurchlässigkeit und abwechslungsreichen Mustern entwickelt.

Upcycling mit Alpaka
Re-Up-Cycle by Incalpaca: Der Alpaka-Spezialist Incalpaca hat eine hochspezialisiertes Re- und Upcycling-
Verfahren entwickelt, bei dem aus Textilresten neue langlebige High-End-Gewebe entstehen. Dafür kauft Incalpaca Stoffreste wie Webkanten, Muster oder Garne aus alten Lagerbeständen, mischt diese mit Alpakafasern und stellt daraus hochwertige Re-Up-Cycle-Garne her. Verwendet werden können Abfälle aus Wolle und Nylonmischungen sowie recyceltes Nylon, mit Acryl und Baumwolle hingegen funktioniert das Verfahren nicht. Auch extrem kurze Fasern können verarbeitet werden. Das Ergebnis: 120.000 Kilogramm recyceltes und upcyceltes Garn jährlich – zum Beispiel für Capes, Throws und Mäntel.

UV-sensible Garne
Sunkolor by Panorama Fabrics: Mit dem zunehmenden Klimawandel steigt auch die Menge der unsichtbaren UV-Strahlen der Sonne. Das Problem daran: Die jeweilige Stärke ist mit bloßem Auge nicht zu erkennen. Genau das kann mit Sunkolor gelingen, denn das Material hilft dabei, die Sonneneinwirkung visuell wahrzunehmen. Das Berliner Design Studio Panorama Fabrics hat eine Technologie für Garne entwickelt, die UV-Strahlen in Textilien sichtbar machen. Durch die Sonneneinstrahlung verwandelt sich die Farbe der Sunkolor-Garne und zeigt für die menschliche Haut gefährliche UV-Indexbereiche an.

Nachhaltige Innovationen werden den Besucher:innen auch auf der kommenden MUNICH FABRIC START Spring.Summer 24 vom 24. bis 26. Januar 2023 im MOC München sowie auf der BLUEZONE und im KEYHOUSE vom 24. bis 25. Januar 2023 auf dem Zenith Areal quer durch alle Schritte der Wertschöpfungskette finden: von zahlreichen zukunftsweisenden Materialien über wasserloses Färben und sauerstoffbasierte Veredlung bis hin zu KI-gesteuerten Verfahren.

Avgol®, an Indorama Ventures Limited company, has been honoured with the Supplier Excellence Award by leading global brand Procter & Gamble.

The award was in recognition of Avgol, a leader in the manufacture of high-performance nonwoven fabric solutions, ‘being a notable and valuable supplier over the last fiscal year’ to the P&G Baby Care Business Unit.

Avgol CEO Tommi Bjornman said receiving the honour from P&G for the first time is a source of great pride for the company. “The assessment process for the award focuses on us as the supplier showing outstanding contributions across a range of key categories,” he said. “I am delighted and proud that the Avgol team was unanimously identified as being strongest in terms of our collaboration with the customer, as well as in our continuous improvement efforts across all regions of P&G’s global Baby Care program.

“It was heartening that, in making the award, P&G further noted that Avgol’s efforts have significantly assisted in their own commercial growth during a challenging period for the Hygiene market,” he said.

In 2018, Indorama Ventures Limited (IVL), a leading petrochemicals producer and global integrated leader in PET and fibres, acquired majority ownership of Avgol, resulting in a focused and faster growth of Avgol Nonwovens.

“With the combined financial, technical, commercial strength and expertise of Avgol and IVL, Avgol has been working hard to develop innovative products, putting sustainability front and centre in our plans for the future and ensuring we deliver the very best product and service to our customers around the world,” said Tommi Bjornman.

In view of the easing of pandemic restriction policies in China, the Spring Editions of Intertextile Shanghai Apparel Fabrics, Yarn Expo and Intertextile Shanghai Home Textiles have been moved to the new timeslot of 28 – 30 March 2023. This will allow both local and international fairgoers more time to prepare for their participation, with a higher industry turnout now expected at the three fairs. The fairs will still be located at the National Exhibition and Convention Center in Shanghai where they were originally due to be held from 8 – 10 March.

Discussing the change of dates, Ms Wilmet Shea, Deputy General Manager of Messe Frankfurt (HK) Ltd explained: “After talking to our stakeholders, we believe adjusting the spring show dates to the end of March is the right move. It provides enough time for exhibitors and visitors from local and abroad to plan for the fairs and capitalise on the ample international business opportunities brought by the reopening of China’s border.”
