From the Sector

The DITF is leading the joint project "DACCUS-Pre*". The basic idea of the project is to develop a new building material that stores carbon in the long term and removes more CO₂ from the atmosphere than is emitted during its production.       

In collaboration with the company TechnoCarbon Technologies, the project is now well advanced - a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO₂ balance of the material:

Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of stone dust. This is very reactive due to its large specific surface area. Silicate weathering of the rock dust permanently binds a large amount of CO₂ from the atmosphere.

Carbon fibers in the form of technical fabrics reinforce the side walls of the wall elements. They absorb tensile forces and are intended to stabilize the building material in the same way as reinforcing steel in concrete. The carbon fibers used are bio-based, produced from biomass. Lignin-based carbon fibers, which have long been technically optimized at DITF Denkendorf, are particularly suitable for this application: They are inexpensive due to low raw material costs and have a high carbon yield. In addition, unlike reinforcing steel, they are not susceptible to oxidation and therefore last much longer. Although carbon fibers are more energy-intensive to produce than steel, as used in reinforced concrete, only a small amount is needed for use in building materials. As a result, the energy and CO₂ balance is much better than for reinforced concrete. By using solar heat and biomass to produce the carbon fibers and the weathering of the stone dust, the CO₂ balance of the new building material is actually negative, making it possible to construct CO₂-negative buildings.

The third component of the new building material is biochar. This is used as a filler between the two rock slabs. The char acts as an effective insulating material. It is also a permanent source of CO₂ storage, which plays a significant role in the CO₂ balance of the entire wall element.

From a technical point of view, the already realized demonstrator, a wall element for structural engineering, is well developed. The natural stone used is a gabbro from India, which has a high-quality appearance and is suitable for high loads. This has been proven in load tests.  Bio-based carbon fibers serve as the top layer of the stone slabs. The biochar from Convoris GmbH is characterized by particularly good thermal insulation values.

The CO₂ balance of a house wall made of the new material has been calculated and compared with that of conventional reinforced concrete. This results in a difference in the CO₂ balance of 157 CO₂ equivalents per square meter of house wall. A significant saving!

Increasing energy and resource efficiency in the construction sector will be key to the EU’s ambition of achieving climate neutrality by 2050. By enabling the manufacture of strong, durable and lightweight products, composite materials can help the construction sector improve its environmental sustainability, as well as reduce total lifecycle costs. The latest EPTA industry briefing, Pultruded composites contribute to a more sustainable future for construction, discusses how pultruded composites answer the need for materials offering high performance, faster installation, corrosion resistance and low maintenance.

The report is available to download from the EPTA website.

The future of construction
As one of the largest global users of energy and raw materials, the construction industry is under immense pressure to improve its sustainability. At the same time, it must respond to demands for improved performance and reduced total cost of ownership. New materials will be needed to minimise the use of natural resources, enable a reduction of carbon footprint and facilitate circular economy practices. Choosing the optimum materials required for durability throughout the lifecycle will be increasingly important. A shift to off-site production is also forecast, where factory-controlled environments and automated processes can improve quality control, lower waste, and reduce work on site.

Lightweight pultruded parts can be pre-assembled into modules or complete structures in the factory for faster installation on site. Lightweight profiles lower energy use during transportation and installation, and a longer service life combined with minimal maintenance can deliver a reduced through-life carbon footprint. Pultruded parts such as profiles, gratings, beams, tubes and planks are increasingly found in a range of building, construction and infrastructure applications. Examples include bridge decks, fencing, stairs and handrails, train platforms, cladding, utility poles, modular building concepts, and window frames.

One application offering large growth potential for composites is bridges. Composite bridges are being designed to provide a service life of 100 years and unlike steel bridges do not require regular repainting to protect them from corrosion. Over recent years, pultruded glass fibre composite has become a highly popular choice for pedestrian and cycle bridges. Pre-fabricated ‘easy fit’ bridge decking planks, pre-assembled bridge modules and complete bridge ‘kits’ are now available. Corrosion-resistant composite bridges are ideal for use near water or on the coast, and in remote locations where regular maintenance operations would be difficult. A composite bridge can deliver the same performance as a steel structure with a weight saving of up to 50% or more. This enables more streamlined bridge designs which require less substantial supporting structures and foundations, greatly reducing consumption of materials and energy. Lightweight also results in easier logistics and simplified installation. Pultruded are more easily transported to the construction site, with lower fuel consumption, and easier to move on site, often reducing labour requirements and the capacity of lifting equipment.

A lifecycle approach
As the construction industry looks to the future, the environmental and economic benefits of composite materials linked to easier logistics and installation, durability and low maintenance are becoming increasingly valued. More projects are demonstrating the benefits of composite materials and standards covering the design, fabrication and installation of pultruded profiles are making it easier for the construction industry to use them. With ongoing development and collaboration, pultrusion has the potential to contribute to a more sustainable future for construction and many other industries. EPTA will continue to promote the advancement of pultrusion technology and its applications and foster sustainable practices within the industry.

Trützschler Card Clothing (TCC), technology leader in the manufacture of high-performance card clothings for textile yarn processing, is expanding its site in Neubulach, Germany. With the twelve-million-euro investment, the supplier for the international textile machinery industry is expanding its production, warehouse and office capacities. A groundbreaking ceremony will take place during the coming winter.

The new building will expand the warehouse and logistics area by 600 square meters, to make a total area of 2,800 square meters. In the optimized cube of the new hall, a modern warehouse system will double the storage capacity. There will also be a fully automated warehouse for coils for sawtooth wires. During the construction phase, logistics and shipping will be temporarily outsourced to Pforzheim-Büchenbronn.

The move into the new building is planned for 2024. TCC will also expand the range of services and the production intensity at the site, while optimizing the process flows. Trützschler intends to recruit the additional employees required within a short timeframe by hiring new staff and offering apprenticeships at the Neubulach site. TCC employs more than 130 people in Germany, with a further 220 people employed worldwide at locations in Brazil, China, India, Mexico, Turkey and the USA.

Overall, the production area will be expanded from 4,000 to 5,400 square meters. This will enable the process flows to be optimized. The office space will be increased to 1,000 square meters. An additional level of the building will provide modern workplaces for administration and sales.

The new building will also improve access and exit routes for truck traffic. This will provide considerable relief for the local neighborhood in terms of noise emissions and other factors. Good integration into the region is very important to Trützschler. All contracts for planning, construction and air conditioning technology have been awarded to local companies.

In the future, TCC will operate its production facility in Neubulach in a climate-neutral manner. This will contribute important progress toward achieving the ambitious climate goals of the Trützschler Group. The new production facility will meet the highest requirements for energy efficiency and climate protection. Heating is provided by process heat recovery and geothermal energy. In addition, the company produces green electricity via its own solar panels.

"By expanding our business here in Neubulach, we are strengthening our presence in this area and our leading global market position too," says Managing Director Peter Gäbler. The Trützschler Group SE is also investing in India to build a new site with over 100,000 square meters for the Spinning, Card Clothing and Nonwovens business units. "It is important to be close to the customer worldwide because our foreign companies make a significant contribution to the success of the Group," says Gäbler.

TCC achieved another record sales result in 2021. Demand for the technology components for carding fibers in spinning mills and for carding in nonwovens production has increased significantly. The steel sawtooth wires, which are wound onto coils and produced for customers around the globe, eventually get worn down by use in production processes – so it is necessary to replace them regularly. For this reason, further growth is expected in 2022 and beyond.

The sustainable collaboration and innovation between Indorama Ventures (IVL), Auping and TWE Group presented a certified cradle to cradle process for mattress components across nonwoven applications, at Techtextil, Frankfurt, 21st to 24th June 2022.

Using circular research and design, the industry partnership between IVL Mullagh (Ireland), Auping and TWE Group has resulted in a perpetual, sustainable economic business model, for manufacturers globally. The inclusion of safe raw materials within mattress manufacturing allows the materials to be easily disassembled at the product’s end of use in order to be further reused as same components or recycled into new raw material at the same quality level, to enable versatile textile applications.

Designed for disassembly to optimize the use of existing resources, reduce carbon footprint and support customer objectives all along their customers’ supply chain. This circular industry collaboration begins with design, where the mattress is constructed using only two different base materials, 100% PET polyester textiles and steel wire pocket springs connected with Niaga®️, a non toxic reversible adhesive, making the mattress easy to disassemble and recover.

IVL, Auping and TWE’s shared vision for a better world is demonstrated through their connected and innovative circularity that helps to close the loop. Auping collects, sorts and separates the collected fabrics, which then go to IVL Mullagh for processing, melting and extrusion to form polyester staple fiber. These staple fibers are then converted by TWE Group into nonwovens for use in Auping’s Evolve mattress, a fully circular mattress. Following the end of mattress use, the material recovery process simply starts again.

Auping estimates that annually more than 40 million mattresses are disposed of in Europe alone, the majority of which are incinerated. Their take back system in the Netherlands ensures that when their new mattress is delivered, the old mattress is retrieved and recycled, irrespective of the brand, ensuring existing materials are continually optimized, diverted from landfill and kept in use to achieve a circular economy.

• 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

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.

• Riri’s SS 2022 collection explores the mind of the future.
• Bright colors, vintage themes as well as timeless designs and attention to detail, combined with concepts that highlight history and processes.

Riri Group’s gaze looks to the future once more, offering a line of accessories where creativity meets cutting-edge technology. This is the scenario spawning the new SS 2022 collection; a range of innovative proposals each representing a different emotional response to the pandemic, an attempt to interpret the emotions, needs and desires of consumers in the coming years.

The Italian-Swiss group, that for almost a century has committed to creating zips and buttons for the world’s most important fashion brands, doubles down on its forward-looking vision. The result is SS 2022 collection, featuring three different aspirational paths to read into the emerging feelings of the “new normal” that is our time and that may characterize the near future.

REJOICE
Inspired by sensations of euphoria and breaking free from melancholy through evasion and exuberance, Rejoice is the line that sees in positivity and joy of re-living the answer to the months of pandemic and negativity. The optimism that is to come takes the form of a creative and extrovert style, even when it comes to accessories. The inspiration, a triumph of bright colors and timeless styles, comes straight from the streets of Boca, one of Buenos Aires’ most popular neighborhoods thanks to its combination of colors and creative scene. Thus, the Eloxal rio zip is presented once again: with its aluminum chain and colored teeth, matched with a multi-color effect puller. In the range, we can also find the Nylon zip, featuring changing colors matched with buttons that echo their color variations, or the Filmetal 14 zip, big and with eye-catching writings, embossed on the tape.

REBIRTH
Going back to the future, in a more respectful and responsible way, through a rebirth that comes to be thanks to a closer relationship with nature. In this line history and processes through which the product is made are pivotal to tell a new way to approach the world. The range comprises zips and buttons developed with natural material and processed manually. A return to the basics as well as the constant research to reduce resources use respecting the planet are foundation of this line. Part of the Rebirth line are the copper jeans buttons, with a special water-based paint finishing, transparent and protective, or the hemp-derived bio-plastic eyelets, as well as the galalite buttons, a particular bio-degradable plastic, derived from processed milk proteins. A major innovation are our tapes entirely made of recycled polyester, evidence of the commitment by Riri Group to reuse resources.

TIMELESS
Timeless elegance, essential luxury mixed with the highest quality standards for top-of-therange products. Design, materials and colors featuring in this line break away from seasonal trends to become timeless must-haves, essential yet elegant. Every piece is cared for in every detail, created specifically to leave a lasting mark. Buttons, chains and pullers are either made of gold and silver, or they feature the clean and elegant tone of stainless steel. Among the zips, stand out Metal and Simmetrical with luxury finishings, whilst tapes are made with refined materials, such as leather and satin. Essential yet researched, this range comes with square and oval cuts, with geometry being functional and complementary to a timeless elegance.

• Technology, creativity and sustainability
• Recycled materials, bright colours, eclectic shapes: excellence is in the details, and the new creations by the Italian-Swiss group have plenty to say.

Mendrisio – Looking at the new Fall-Winter 2021-2022 collection of the Riri Group, it almost seems as if the difficult months to which the pandemic has forced the whole world, have been another new – though unwanted – challenge for the Italian-Swiss company. A testbed that sparked the mind and lit the fire of creativity. Therefore, today, the brand ingredient which for over 80 years has embellished the
garments designed by major fashion system brands with top-quality zips and buttons, also introduces a wide range of heterogeneous creations, intended to cover different aesthetic and functional requirements on the market.

This collection has been divided into three macro-topics; it is a new chapter in the history of the Group.

LIFE SERVING
Keyword: sustainability. Or, more romantically, “Reuse with love”. From the use of materials produced using organic waste and recycled plastics to actual destocking – the re-introduction on the market of unsold items to give them new life through a restyled shape: the topic of “life serving”, for Riri, translates into the meticulous and constant search for materials with a low environmental impact and in the committed attempt to reduce the use of plastic to a minimum. This is why the Group has decided to use recycled polyester tapes, made with new organic cotton, pullers coated with cork, created using 100% recycled plastics or rubber taken from the sole of shoes. Stainless steel – an exceptionally resistant and sturdy material, as well being subject to no galvanic treatments and highly recyclable – characterizes chains and pullers, while the Nylon zip consists of fully recycled tape and chain, and Decor introduces a new 100% polyamide version. On the button side, “life serving” includes buttons with a cork coating, the Zero button with coating made of recycled Meryl polyamide and the F4 with a 100% recycled Nylon head and the heads made of APILON 52 (rubber made of 65% vegetable oils and energy from renewable sources) coated with microfiber from the company Alcantara.

ENGINEERING
This is definitely the most rigorous yet progressive section in the collection, drawing on technological innovation and on uncertainties related to the current situation, to play with shapes, colours and materials. Between zips and buttons there is a prevalence of squared and minimal shapes, also on the tapes of the zips through sublimation and digital printing techniques. The leading colour is grey in its variation of hues, where the insertion of coloured tones sometimes stands out. The leading material, on the other hand, is metal.

OVER SHOCK
A creative topic where “exaggeration” is the keyword, a trend whose style and character somehow remind us of Gen-Z, apart from being especially suitable for outdoors. “Over state” uses the hip hop mood and settings of the Nineties, taking them to the extreme, enlarging shapes and focusing on bright and fluorescent colours such as purple, yellow, blue, orange or green. An example of this is Storm Evo, a zip which is popular in the outdoor sector for its high levels of water resistance and strength, which features a new electric blue chain and tape with reflecting side strips. Also outstanding in terms of originality is the new purple puller, with its anti-theft shape, fixed onto a fluorescent yellow chain. The perfect expression of this category are zippers such as Decor, Nylon and Aquazip, especially recommended for the outdoor sector in general.

COLLECTION HIGHLIGHTS: RESTYLING AND INNOVATION
All the macro-categories selected for the FW 21-22 seasons are included in some special product innovations, most notably the even more minimal and thin shapes of some buttons and the introduction of five different colours for the small synthetic ring, a real point of strength in Cobrax pressure buttons. Also the range of magnetic buttons is complemented by the addition of two extra snaps. As regards zips, the Riri Group team has been working on careful restyling of shapes, more specifically in the shapes of Decor zip bodies – ideal for the luggage industry – further improved from both an aesthetic and functional viewpoint.
