From the Sector

• Wiederaufbau nach Hochwasserereignissen auch bei sehr weichen Böden
• Bau der Swistbachbrücke in Rekordzeit mit Geogitter-Bewehrter-Erde
• Technische Infrastrukturbauwerke nachhaltig und CO2 sparend errichten

Zunehmende Extremwetterereignisse, wie auch zuletzt in Teilen von Nordrhein-Westfalen, Rheinland-Pfalz und anliegenden europäischen Nachbarländern, erfordern grundsätzlich schnelle und sichere Wiederaufbaumaßnahmen, damit Bewohner und die Wirtschaft vor Ort nicht langfristig durch infrastrukturelle Missstände eingeschränkt sind.

Aufräumen und wiederaufbauen mit Geotextilien
Beim Wiederaufbau der Infrastruktur können Geotextilien an vielen Stellen für einen schnellen Baufortschritt eingesetzt werden. So können beispielsweise dringend benötigte temporäre Versorgungsstraßen, Baustraßen und Arbeitsplattformen mit Geogittern oder Bewehrungsgeweben, auch bei sehr weichen Böden, schnell und sicher errichtet werden. Auch die temporäre Lagerung von Abfällen und kontaminierter Schlämme ist mit geosynthetischen Schadstoffbarrieren, Filtern und Schlammentwässerungsschläuchen möglich, um auch die Umwelt bestmöglich vor Schadstoffeinwirkungen zu schützen.

Aufbau der Swistbachbrücke in Heimerzheim in Rekordzeit
Der Neubau der Swistbachbrücke in Heimerzheim, die die überregional wichtige L182 über den Swistbach führt und damit die Großräume Euskirchen, Swisttal und Bornheim verbindet, ist eines dieser erfolgreichen Wiederaufbauprojekte. Durch die Zerstörung der alten Brücke durch das Hochwasser war ein kompletter Neubau erforderlich. Bereits nach drei Monaten konnte die neue Brücke im Dezember 2021 wieder für den Verkehr freigegeben werden.

Möglich wurde die Realisation nach kurzer Zeit durch das innovative Schnellbausystem der HEITKAMP Unternehmensgruppe – welches gemeinsam mit HUESKER entwickelt wurde: das System HEITKAMP Schnellbaubrücke®. Die tragenden Säulen des Systems bzw. die Widerlager werden aus verbundflexiblen Geogittern und lokal verfügbaren Böden hergestellt. Sie bilden die langfristig sicher tragenden Schwerlastelemente.

Konstruktionen aus Geokunststoff-Bewehrter-Erde ermöglichen grundsätzlich einen sehr schnellen Aufbau von Brückenwiderlagern. Anders als in Deutschland, zählen Bewehrte-Erde-Konstruktionen in den Niederlanden schon sehr lange zu den Standardbauweisen, mit denen ein Großteil von Infrastrukturmaßnahmen realisiert werden.

Durch die Konstruktion aus Geogittern und Erde konnte die Bauzeit der Widerlager der Swistbachbrücke von drei Monaten auf zehn Tage reduziert werden. Durch weniger Ressourceneinsatz und weniger Materialtransporte wurde zusätzlich auch CO2 eingespart.

BB Engineering GmbH (Germany) delivers a melt filter for recycling PET flakes to polyester manufacturer Indorama Polyester Industries (Thailand). Indorama will be using the type NSF38 filter in its recently assembled recycling system in order to produce rPET granulate from flake PET bottle waste. The NSF38 filter enables continual filtering – in other words, the system switches from one filter to the other during the process without the need for conversion shut-downs. The filter allows the processing of consumer waste for example, in the form of shredded PET bottles into new, high-quality rPET granulate. This granulate is subsequently processed into manmade fibers in spinning systems.

The NSF38 is a switchable filter with a filter surface area of ap-prox. 16 m2 on each side, with throughputs of between 1,000 and 1,900 kg/h. The filter inserts each contain 19 pleated filter candles (60 x 1,000mm Ø). The filter medium comprises a sin-tered metal fiber nonwoven with a filtration fineness of 25 μm. This ensures that the melt remains free of contaminants and gel particles, which in turn enables the production of high-quality end products.

• Renewable Carbon Initiative (RCI) published a strategy paper on the defossilisation of the chemical and material industry with eleven policy recommendations

The Renewable Carbon Initiative, an interest group of more than 30 companies from the wide field of the chemical and material value chains, was founded in 2020 to collaboratively enable the chemical and material industries to tackle the challenges in meeting the climate goals set by the European Union and the sustainability expectations held by societies around the globe.

RCI addresses the core of the climate problem: 72% of anthropogenic climate change is caused directly by extracted fossil carbon from the ground. In order to rapidly mitigate climate change and achieve our global ambition for greenhouse gas emission reductions, the inflow of further fossil carbon from the ground into our system must be reduced as quickly as possible and in large scale.

In the energy and transport sector, this means a vigorous and fast expansion of renewable energies, hydrogen and electromobility, the so-called decarbonisation of these sectors. The EU has already started pushing an ambitious agenda in this space and will continue to do so, for instance with the recently released ‘Fit for 55’ package.

However, these policies have so far largely ignored other industries that extract and use fossil carbon. The chemical and material industries have a high demand for carbon and are essentially only possible with carbon-based feedstocks, as most of their products cannot do without carbon. Unlike energy, these sectors cannot be “decarbonised”, as molecules will always need carbon. The equivalent to decarbonisation via renewable energy in the energy sector is the transition to renewable carbon in the chemical and derived materials industries. Both strategies avoid bringing additional fossil carbon from the ground into the cycle and can be summarised under the term “defossilisation”.

To decouple chemistry from fossil carbon, the key question is which non-fossil carbon sources can be used in the future. Rapid developments in biosciences and chemistry have unlocked novel, renewable and increasingly affordable sources of carbon, which provide us with alternative solutions for a more sustainable chemicals and materials sector. These alternative sources are: biomass, utilisation of CO2 and recycling. They are combined under the term “renewable carbon”. When used as a guiding principle, renewable carbon provides a clear goal to work towards with sufficient room to manoeuvre for the whole sector. It enables the industry to think out of the box of established boundaries and stop the influx of additional fossil carbon from the ground.

The systematic change to renewable carbon will not only require significant efforts from industry, but must be supported by policy measures, technology developments and major investments. In order to implement a rapid and high-volume transition away from fossil carbon, and to demonstrate its impact, a supportive policy framework is essential. The emphasis should be put on sourcing carbon responsibly and in a manner that does not adversely impact the wider planetary boundaries nor undermines societal foundations. An overarching carbon management strategy is required that also takes specific regional and application-related features into account, to identify the most sustainable carbon source from the renewable carbon family. This will allow for a proper organisation of the complex transition from today’s fossil carbon from the ground to renewable energy and to renewable carbon across all industrial sectors.

RCI has developed eleven concrete policy recommendations on renewable carbon, carbon management, support for the transformation of the existing chemical infrastructure and the transformation of biofuel plants into chemical suppliers. The policy paper “Renewable Carbon as a Guiding Principle for Sustainable Carbon Cycles” is freely available for download in both a short version and a long version.

Die Umlage nach dem Erneuerbare Energie Gesetz (EEG-Umlage) soll zum 01. Juli 2022 entfallen. De facto ist die Streichung der EEG-Umlage um 6 Monate vorgezogen worden, sie war ohnehin für den 01. Januar 2023 geplant. Auch die bereits erfolgte Senkung um 43 % zum Jahreswechsel war durch den Preisanstieg überkompensiert worden. Ähnlich wenig Effekt könnte die vollständige Abschaffung haben, die 3,7 Cent pro Kilowattstunde Strom ausmacht.

Das am 23. Februar vorgestellte "Entlastungspaket", um den massiven Preisanstieg im Energiesektor abzufedern, richtet sich vor allem an einkommensschwache Haushalte und den Mittelstand. Was bedeutet der Baustein "Wegfall der EEG-Umlage" für energieintensive Industrien wie die Produzenten von Chemiefasern, ohne deren Vorprodukte insbesondere technische Produkte nicht herstellbar wären, wie sie beispielsweise auch essentiell für die Energiewende sind.

"Es freut uns", so der Geschäftsführer der Industrievereinigung Chemiefaser Dr. Wilhelm Rauch, "dass die Koalition jetzt auch unsere Beurteilung des Energiemarktes und des wettbewerbsverzerrenden Faktors Energiekosten erkannt hat. Dies kommunizieren wir bereits seit zehn Jahren. Leider kommt diese Einsicht spät - vermutlich zu spät. Alle unsere Unternehmen werden nur marginal von einer solchen Senkung profitieren.“

„Aktuell legen wir bei jeder Tonne Fasern, die produziert wird, Geld drauf,“ sagt der Vorsitzende des IVC-Energieausschusses, Frank Heimann, Managing Director der Advansa Manufacturing GmbH. Was das für den Industriestandort Deutschland und letztlich auch die Europäische Union bedeutet, braucht wenig Phantasie. „Wenn wir an der hohen Qualität unserer Erzeugnisse festhalten und wenn wir weiterhin höchsten Arbeitnehmer- und Verbraucherschutz leben wollen, brauchen wir faire Wettbewerbsbedingungen.“ fordert Klaus Holz, 1. IVC-Vorsitzender (General Manager Trevira GmbH). Ein Teil der Fairness bedeute global vergleichbare, also geringere Energiepreise. Die Gefahr, dass ansonsten nur noch Produkte als Importe unsere Märkte erreichten, die mit Blick auf den Klima-, Umwelt-, Verbraucher- und Arbeitnehmerschutz unter deutlich anderen Bedingungen hergestellt wurden, sei greifbar nahe.

Der Entfall der EEG-Umlage stelle nur einen Tropfen auf dem heißen Stein dar. Weitere Maßnahmen seien gefragt. Da knapp die Hälfte der Stromkosten auf vom Staat zu verantwortenden Abgaben bestehe, sollte es eine leichte Übung sein, diese zu reduzieren. Als nächste Maßnahme zur Kostensenkung böte sich beispielsweise die Streichung der Stromsteuer an. Die produzierenden Unternehmen bräuchten schnelle Entlastung.

• The “new normal” by Südwolle: responsible, seasonless and high performance

The concept of seasonality in the F/W 2023/24 collection is increasingly vague, in favour of more functional categories in terms of performance, sustainability, innovative content and style.

Yarns are predominantly pure wool or blends, corresponding with the new concept of “dressing well” which is gaining ground among consumers – an individual style that promotes wellbeing at various times of the day, a fluid, personal idea of elegance, that fits daily activities with ease.

The new formal replaces the traditional suit with “smart casual” jackets and trousers -comfortable, and carefully cut, they feature quality materials that guarantee wearability as well as durability. Focus on these factors makes for more informed and less impulse buying.

The renewed interest in heritage is met with Südwolle's wool know-how and its basic essentials, updated to make them more sustainable by choosing certified fibres and chlorine-free anti-shrink treatments, for products with a longer lifespan thanks to domestic washing at low temperatures.

Sustainable innovation attentive to performance and durability goes hand in hand with the selection of earth-friendly recycled, recyclable and traceable materials blended with natural fibres.

Overview of the collection
The words inspiring the new collection are: sustainable, responsible, natural, recycled and high-performance.

A leading position goes to the OTW® line of weaving yarns made with Omega Twist® technology, developed and patented by Südwolle Group, which gives yarns enhanced performances in terms of reduced pilling, greater elasticity, strength and durability.

Espresso TEX Nm 48/2 (100% untreated wool,20.5μ) was created to value the authentic naturalness of wool. Made with undyed, untreated merino wool, it is a twisted yarn for weaving, ideal, for example, for flannel suits and jacket. It is available in 4 shades of brown obtained by mixing different percentages of untreated raw wool and undyed, naturally brown wool.
Eolo Nm 24/2 (100% wool 20.5 µ) is an example of circular production and reuse of recycled wool within the Karma project. Starting with in-house pre-and post-production waste, a partly carded, partly combed, product is created at Südwolle Group facilities where this type of process can be carried out.

Rhein GOTSNm 64/1 and Nm 64/2 (100% wool 19.5 µ) is the new pure woolyarn with GOTS –Global Organic Textile Standard certification, which certifies its organic provenance. The same traceable origin applies to Lerici GOTS X-COMPACT®Nm 60/1 (70% GOTS certified wool 19.5μ, 30% Schappe Mulberry silk), a glossy yarn with reduced pilling effect for improved anti-abrasion performance, obtained with X-COMPACT® spinning technology.

Performance paired with reduced energy consumption is the added value of SRP ClarkNm 60/2 (48% wool 23.5μ, 44% cationic polyester, 8% Donegal viscose), also available in a stretch version. The cationic polyester can be dyed blended with the wool, making double dying unnecessary and so saving on water and energy consumption. The addition of pre-dyed red, green or brown Donegal viscose to the blend creates a fluid look enhanced with slubbing and micro-nep effect.

Rosvic Nm 40/2 (98% wool 19.5μ, 2% Lycra®44 dtex) is a twisted yarn with Basolan treatment for comfort fabrics. It has a slightly textured surface with a contrasting or tone on tone micro mouliné pattern.

Key players among the circular knitting and hosiery yarns are Basak Nm 80/1(80% wool TEC. 20% polyamide 2.2 dtex), OTW® Barone GRS Nm 60/2(60% wool 23.5 µ TEC, 40% RENU™ recycled cationic polyester 2.2 dtex) and OTW®Concorde Nm 88/2(100% wool 19.3 µ TEC), available in the new colour cards.

Dilo, a leading equipment supplier of complete lines for staple fibre nonwoven fabric production, will exhibit at IDEA 2022 in Miami, end of March.
 
The most recent machine concepts from DiloGroup companies DiloTemafa, DiloSpinnbau and DiloMachines will be promoted with the emphasis on new equipment components which improve product quality, increase line capacity and also enable new opportunities in nonwoven production.
 
DiloTemafa will promote the improved bale opener series “Baltromix Pro” with design features for the operating assistance with the I4.0 components “Bale Timer”, cleaning control, better accessibility for maintenance and the “DI-LOWATT” system for energy savings in fibre transport. The proven carding willow with modified workers and separate drives to create the prerequisites for a good fine opening will also be part of the presentation as well as the fine opening stage which may be installed over the material box of the new card feeder FRS-P to achieve a high dosing accuracy in cross and longitudinal direction.  
 
DiloSpinnbau has a new “Unifeed” card feeder (VRS-P) which combines the principle of volumetric charged feeding with the characteristics of a chute feeder but without the conventional overhead trunk which allows for lower ceiling height requirement. The fibre flock matt is condensed by a vacuum delivery apron to give better uniformity of mass distribution. The distribution over the working width is controlled by additional flaps. This feeder can be adapted for medium/fine, coarse/medium or long staple fibres.
 
The “VectorQuadroCard” by DiloSpinnbau incorporates a modular transfer group between breast and main section. The quick change facility of this roller group provides different carding options. The delivery system is also flexible to provide parallel laid, random or condensed web. The preopener section on this card has 4 worker/stripper pairs with five pairs on the main cylinder. Emphasis is on high throughput with good web quality.
 
The revised HyperLayer NT offered by DiloMachines presents the latest state-of-the-art highspeed precision layering technique setting new standards which play an important role especially in hydroentanglement lines. In this application, it is important to achieve layering speeds up to 190 m/minute using sophisticated viscose fibres and a layering width of about 4 m while at the same time having a high layering precision in cross and longitudinal direction.  
 
DiloMachines will also present its portfolio to improve quality and reduce costs. The FutureLine study “3D-Lofter” – first presented at ITMA 2019 in Barcelona – is part of this programme. In this study individual web forming units can deposit fibre masses on freely programmable spots in longitudinal and cross direction thus saving overall fibre mass in applications such as deep moulded parts for the automotive interior. This ability reduces costs in production and operation. The “IsoFeed” concept for a more even flock mat for direct cards and aerodynamic web forming is another interesting field of web mat quality improvement.

The 2021 C.L.A.S.S. Icon Award Portuguese brand Duarte is ready to presents its Fall/Winter 2022/23 collection developed in collaboration with C.L.A.S.S. Eco Hub during Milan Fashion Week. With the support of WHITE, Duarte’s creations will be featured as a special project at WSM (WHITE Sustainable Milano) platform space inside “Unveiling the fashion Backstage”, a docu-event focusing on an immersive journey into the amazing world of premium and smart supply chains that make innovative and responsible fashion wardrobes a reality.

For its second collection Duarte still counts on C.L.A.S.S. support in sourcing materials and communication activities as part of the Icon Award yearly program. The streetwear designer Ana Duarte, with the help of the Milanese hub, is back with a renewed collection that counts 40 pieces continuing the concept and the story behind the previous World Keeper: the irresistible superhero Tadao - Ana Duarte’s dog – fighting against the environmental issues created by mankind and personified as Smog Man (air pollution), Fire Man (climate change), Deforestation Man (forests destruction) and Wave Man (water overconsumption).

This time the inspiration is also Street Dance drawn directly from the city streets, with majorly unisex pieces (apart from some small specific details linked to sizes or ergonomics) and materials that both respect the planet and keep you warm. The prints drawn from ripped posters giving birth to a sort of new style named “Eco-Street Dance”.

The collection presents a selection of urban pieces for everyday superheroes, fighting against environmental issues - with a holistic approach to sustainability values thanks to the synergy with C.L.A.S.S. and its Back in the Loop area: a section dedicated to alternative and sustainable sourcing against the massive amount of materials and textiles produced that are not used and discarded by the fashion system. This is mostly powered by MAEBA International - and its ReLiveTex® fabrics - leader in selecting and repurposing premium Italian fabrics with exceptional 60 years of expertise in collecting high-quality materials from leading brands and textile manufacturers, and one of the first companies at an international level to be accredited for the UNI EN ISO 14021 certification which grants the traceability of the collected materials.

The linings complete the full sustainable picture, thanks to Bemberg™ by Asahi Kasei fabrics by Gianni Crespi Foderami. Bemberg™ is a new generation material made from the smart-tech transformation of cotton linter pre-consumer material, converted through a traceable and transparent closed loop process.
