‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.

In Hall 9 (Hightex) the exhibitors will present the complete industry value chain from nonwovens raw materials, production machines and accessories to the endproduct. The related industries covered include hygiene, filtration, fabrics and apparel, medical, automotive, wipes, home furnishings and upholstery. DiloGroup offers tailor-made production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

DiloGroup will inform about complete lines as well as high speed needlelooms for spunbonds. A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further. The new needle pattern 8000X is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

Another strong pillar of the sales program over decades has been fibre preparation and high speed webforming equipment for other nonwoven technologies. The further development of the high-speed layering principle “Hyperlayer” made progress for better CD strength through a combination of inline cards and crossline card with crosslapper. Particularly, carding machines in a working width above 3.5 m up to 5.1 m have been supplied by DiloSpinnbau as complete high speed carding systems, comprising two or even three cards in a line to directly feed the hydroentangling units of various suppliers. Together with DiloTemafa not only have high throughput rates been achieved in the fibre preparation section of the line but also dedusting filtering and air-conditioning systems have been successfully engineered and integrated.

Together with Sicam, Dilo has combined know-how for hydroentangling technology and therefore can provide complete lines as general contractor including equipment for cutting, winding and packaging.

Another interesting machine is the 3D-Lofter, first presented during ITMA 2019 in Barcelona, which offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts with or without repeat are two examples for this technology which explores new application areas for needlefelts.
The 3D-Lofter technology may also be used “inverted” as “IsoFeed” for filling up bad spots in web mats and thus achieves a better homogeneity of spunlace or airlay products.

The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

TEXTILE RECYCLING TECHNOLOGIES BASED ON TEARING
With the acquisition of ANDRITZ Laroche SAS, ANDRITZ has expanded its product portfolio to include airlay and recycling technology as well as bast fiber processing technologies. Complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, for example in the automotive industry, for insulation, mattresses, and furniture felts.

ANDRITZ Laroche offers a complete process range of tearing lines from 50 up to 3,000 kg/h, which can be used for almost all types of pre/post-consumer textile waste. The aim is to preserve the character of the original fibers, for example cotton, by maximizing fiber length, strength and feel.

SGL Carbon: Dynamic business development in Q1 2022 continued

  • Low impact of Ukraine war on business performance in 1st quarter
  • 12.2% increase in sales to €270.9 million based on growth in all four business units
  • Adjusted EBITDA improves by 11.5% to €36.8 million

SGL Carbon generated consolidated sales of €270.9 million in Q1 2022 (Q1 2021: €241.5 million). This corresponds to an increase of €29.4 million or 12.2% compared to the same period of the prior year. All four business units contributed to the pleasing increase in sales. In parallel, adjusted EBITDA improved by 11.5% to €36.8 million in the reporting period.

  • 12.2% increase in sales to €270.9 million based on growth in all four business units
  • Adjusted EBITDA improves by 11.5% to €36.8 million

SGL Carbon generated consolidated sales of €270.9 million in Q1 2022 (Q1 2021: €241.5 million). This corresponds to an increase of €29.4 million or 12.2% compared to the same period of the prior year. All four business units contributed to the pleasing increase in sales. In parallel, adjusted EBITDA improved by 11.5% to €36.8 million in the reporting period.

Sales development
In the first three months of fiscal 2022, the sales increase of €29.4 million was driven by all four operating business units: Graphite Solutions (+€11.3 million), Carbon Fibers (+€6.6 million), Composite Solutions (+€7.2 million) and Process Technology (+€6.0 million).
In particular, sales to customers in the automotive and semiconductor industries and a significant recovery in the industrial applications segment were key factors in the increase in sales. Sales of the Process Technology business unit to customers in the chemical industry also developed pleasingly. The effects of the war in Ukraine, which has been ongoing since the end of February 2022, had only a little impact on SGL Carbon's sales performance in the 1st quarter.

Earnings development
Despite the increasingly difficult market environment in the course of Q1 2022, associated with temporary supply and production bottlenecks at their customers, temporarily interrupted transport routes, and significantly higher energy prices, SGL Carbon was able to keep the adjusted EBITDA margin almost stable year-on-year at 13.6%.  
Adjusted EBITDA increased by 11.5% to €36.8 million in the reporting period. Higher capacity utilization in the business units and product mix effects contributed to the improvement in earnings, together with the cost savings achieved as a result of the transformation. By contrast, higher raw material, energy and logistics costs as of end of February 2022 had a negative impact on earnings. The Carbon Fibers business unit was particularly affected by the energy price increases. One-time expenses of €9.2 million in conjunction with energy transactions burdened the Carbon Fibers business unit in the 1st quarter of 2022.  
To secure our production and delivery capabilities, around 85% of the energy requirements of the entire SGL Carbon for 2022 are price-hedged.
Adjusted EBITDA and EBIT do not include in total positive one-time effects and special items of €8.5 million, among other things from the termination of a heritable building right to a site no longer in use. Taking into account the one-time effects and special items presented as well as depreciation and amortization of €14.1 million, reported EBIT increased by 83.5% to €31.2 million (Q1 2021: €17.0 million). The net profit for the period developed correspondingly and more than tripled from €6.1 million to €21.4 million in a quarter-on-quarter comparison.

Outlook
The sales and earnings figures for the 1st quarter 2022 confirm the stable demand from different market segments. Price increases and volatility in the availability of raw materials, transportation services and energy were largely offset by savings from the transformation program and pricing initiatives at the customers.
For 2022, SGL Carbon continues to expect volatile raw material and energy prices, which were included in their forecast for 2022 at the time of planning. However, there are uncertainties about the extent and duration to which SGL Carbon and the customers will be affected by the impact of the war in Ukraine or temporary supply chain disruptions due to the lockdowns in China. Therefore, SGL Carbon's outlook for fiscal 2022 does not include supply and/or production interruptions at customers or the impact of a possible energy embargo that cannot be estimated at this time.  
SGL Carbon's forecast also implies that factor cost increases can be at least partially passed on to the customers through pricing initiatives. SGL Carbon has also included the revenue and earnings impact from the expiry of a supply contract with a major automobile manufacturer at the end of June 2022 in our forecast.

Sicomin: Upcycled Carbon Fibre from Airbus with GreenPoxy to create Surfboards

Sicomin has confirmed that eco-surfboard specialist NOTOX will use GreenPoxy 56 in its latest line of R-CARBON boards. The new NOTOX R-CARBON boards are the first to use 100% upcycled carbon fibre fabrics recovered from a production waste stream at Airbus.

NOTOX, founded in 2006 and based in Basque, France, has partnered with Sicomin to use GreenPoxy bio-resins in several earlier flax, cork, and bamboo reinforced boards. In a quest to now produce the most sustainable carbon fibre reinforced boards possible, NOTOX has signed a formal agreement with Airbus Nantes to purchase defective carbon fabrics that were destined for landfill.

In a quest to now produce the most sustainable carbon fibre reinforced boards possible, NOTOX has signed a formal agreement with Airbus Nantes to purchase defective carbon fabrics that were destined for landfill.

The new NOTOX technology gives a second life to Airbus carbon fabrics that are declared unusable for aerospace applications due to short roll lengths, an inability to be pre-formed, or other defects. The upcycled materials are combined with Sicomin GreenPoxy 56 and Surf Clear hardener, producing an extremely clear, high gloss laminate with high mechanical properties. NOTOX use a precisely controlled wet lamination process with vacuum bag consolidation to wet out the upcycled woven carbon fabrics and minimise resin consumption in the manufacturing process.

In addition to selecting a high bio-content resin – GreenPoxy 56 derives 56% of its carbon content from plant sources – NOTOX has also sourced the most sustainable carbon fibre fabrics. Full life cycle analysis by NOTOX has shown that using waste carbon fabrics from Airbus is significantly more energy efficient than using other recycled short fibre carbon, confirming the importance of upcycling this key raw material.

Sustainability is key to Beaulieu Fibre International’s long-term strategy, and the company is heavily focused on defining its green portfolio to support evolution in diverse market applications.

Bio-based fibres
From June 2022, Beaulieu Fibres International will offer ISCC+ certification on mono-PP and BICO PP/PE fibres. The fibres will be offered in 1,3-8,9 dtex and will be available with all the main available finish classes (ie. hydrophilic, hydrophobic, etc.) suitable for the main carding and consolidation technologies. These drop-in solutions with no loss in quality will support customers looking to reduce reliance on virgin fossil carbon in their nonwoven and engineered fibre applications. The bio-based fibres enable customers to contribute to the transition towards a circular economy.

Achieving material savings
For customers in industrial segments like geotextiles, high-tenacity HT8 staple fibres enable customers to achieve nonwovens for construction projects with high mechanical performance but with 15% less weight. The durability of the fibres means that customers can use less raw material for a longer service lifetime, supporting more sustainable design in addition to resource reduction.
For hygiene nonwovens, the Meralux fibres provide significant sustainable design advantages. Meralux fibres deliver substantial sustainability benefits including around 55% savings in raw materials, with equivalent carbon emission savings. These emission savings are thanks to weight reduction in nonwovens with the same coverage level and also the higher recyclability of PP/PE compared to BICO materials.

Carbios: White PET fiber from colored textile waste

  • Carbios has succeeded in producing a 100% enzymatically recycled white PET fiber from colored textile waste
  • At the same time, the company has produced the first 100% recycled PET bottles, that have successfully passed the food contact validation tests, from the same textile waste.
  • Carbios received €827,200 for the validation of this final technical stage of the project co-funded by ADEME

Carbios announced the validation of the 3rd and final technical step of the CE-PET research project, co-funded by ADEME3 (France’s Environment and Energy Management Agency), for which Carbios is the lead partner alongside its academic partner TWB. This achievement confirms, once again, the full potential and breadth of Carbios’ enzymatic recycling process, C-ZYME™. This breakthrough innovation makes it possible to produce a wide variety of products of equivalent quality to those of petro-sourced origin from any PET waste, including textiles.

This achievement confirms, once again, the full potential and breadth of Carbios’ enzymatic recycling process, C-ZYME™. This breakthrough innovation makes it possible to produce a wide variety of products of equivalent quality to those of petro-sourced origin from any PET waste, including textiles.
 
The first white PET fiber recycled enzymatically from colored textile waste
Worldwide, around 90 million tons of PET are produced each year, more than 2/3 of which are used to manufacture fibers. However, only 13% of textile waste is currently recycled, mainly for downcycling, i.e. for lower quality applications (such as padding, insulators or rags). By successfully manufacturing at pilot scale a white PET fiber that is 100% enzymatically recycled from colored textile waste, Carbios is paving the way for the circular economy in the textile industry.  C-ZYME™ is now on the doorstep of industrialization and will soon enable the biggest brands to move closer to their sustainability goals.
 
Emmanuel Ladent, Chief Executive Officer of Carbios: « Thanks to our breakthrough process, it will soon be possible to manufacture, on a large scale, t-shirts or bottles using polyester textile waste as raw material. This is a major breakthrough that gives value to waste that currently has little or no value. It is a concrete solution that opens up a global market of 60 million tons per year of potential raw materials and will help to reduce the use of fossil resources. »
 
Separate collection of textile waste soon to be mandatory in Europe
From 1 January 2025 the separate collection of textile waste, which is already in place in some countries, will be mandatory for all EU Member States (European Directive 2018/851 on waste).  Carbios’ process will enable this waste to be sustainably recovered and included in a true circular economy model.
 
These technological validations were carried out as part of the CE-PET research project, co-funded by ADEME3. In particular, the project aimed to develop Carbios’ enzymatic PET recycling process on textile waste. The C-ZYME™ technology is complementary to thermomechanical recycling and will make it possible to process plastic and textile waste deposits that are currently not or poorly recovered. For the validation of this stage of the project, Carbios received €827,200 (€206,800 in grants and €620,400 in repayable advances).

For Lenzing, the project also represents an important step towards strengthening its leadership position in the specialty fiber market and into a carbon-free future.

The construction of the plant located at Industrial Park 304 in Prachinburi, around 150 kilometers northeast of Bangkok, started in the second half of 2019 and proceeded largely according to plan, despite the challenges arising from the COVID-19 pandemic. The recruiting and onboarding of new employees has been successful. Investments (CAPEX) amounted to approx. EUR 400 mn.

“The demand for our wood-based, biodegradable specialty fibers under the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ brands is growing very well. In Asia in particular, we see huge growth potential for our brands based on sustainable innovation. With the production start of the lyocell plant in Thailand, Lenzing reached an important milestone in its growth journey, supporting our ambitious goal to make the textile and nonwoven industries more sustainable”, said Robert van de Kerkhof, Member of the Managing Board.

In 2019, Lenzing made a strategic commitment to reducing its greenhouse gas emissions per ton of product by 50 percent by 2030. The target is to be climate-neutral by 2050. Due to the established infrastructure, the site in Thailand can be supplied with sustainable biogenic energy and contribute significantly to climate protection.

Together with the key project in Brazil and the substantial investments at the existing sites in Asia, Lenzing is currently implementing the largest investment program in its corporate history (with more than approx. EUR 1.5 bn). Lenzing will continue to drive the execution of its strategic projects, which are to make a significant contri-bution to earnings from 2022.

Sumo & Kelheim Fibres: Sustainable and high-performance absorbent washable diaper pad

Up to the age of three, a baby uses around 5,000 diapers. Despite the convenient handling of common disposable diapers, parents are increasingly looking for a healthy and sustainable alternative to these products to avoid waste. In Germany alone, 10 million diapers are disposed of every day.

Ways to solve this dilemma, would be disposable products that are made from bio-based or biodegradable materials, or reusable products with a longer life span replace disposable products.

Founding team Luisa Kahlfeldt and Caspar Böhme combine both with their "Sumo Diapers." These cloth diapers are made entirely of sustainable materials while offering high performance and innovative design.

The Sumo Diaper is a fitted cloth diaper that consists of a waterproof cover and absorbent inserts. The cover is sewn in such a way that a pocket is formed: this is where the absorbent pad is inserted to prevent slipping.

The Sumo Diaper is a fitted cloth diaper that consists of a waterproof cover and absorbent inserts. The cover is sewn in such a way that a pocket is formed: this is where the absorbent pad is inserted to prevent slipping.

To further enhance the performance of this absorbent pad, the Sumo team partners with the viscose special fibre manufacturer Kelheim Fibres, who brings decades of experience from the hygiene sector, especially for sensitive applications where high absorbency is required (such as tampons). Together, Sumo and Kelheim Fibres have developed a high-performance absorbent pad that uses no fossil materials.

The basis are functionalised specialty viscose fibres with adapted cross-sections. Needle-punched / thermobonded nonwovens with a blend of specialty viscose and PLA bicomponent fibres were chosen to ensure the product's washability. PLA stands for polylactic acid made from natural and renewable raw materials. By combining nonwovens, usually found mainly in the single-use sector, with reusable products, Sumo and Kelheim Fibres have chosen a completely new approach.

Inside the pad, the speciality fibres from Kelheim score with their special properties: In the distribution layer (ADL), the trilobal cross-section of the Galaxy® fibre forms capillary channels that enable efficient and optimized liquid distribution and thus optimum use of the capacity of the absorbent core, offering the lowest rewet values.

In the absorbent core, the segmented hollow fibre Bramante stores liquid not only between but also inside the fibre. The liquid remains there even when pressure is applied to the construction, providing excellent rewet values. Bramante can absorb up to 260% of its own weight in liquid. Cotton only achieves values of around 50% here.

The innovative nonwoven construction with the speciality fibres from Kelheim performs significantly better in tests in terms of air permeability, liquid absorption and rewetting than commercially available solutions made of synthetic fibres or cotton in knitted structures, and has earned Sumo diapers a place among the finalists for the IDEA® Long-Life Product Achievement Award.

The launch is scheduled for the first of May.

ITA PhD student Kai-Chieh Kuo was awarded Best Master’s Thesis Award of Walter Reiners-Stiftung

Kai-Chieh Kuo, PhD student at the Institut für Textiltechnik (ITA) of RWTH Aachen University, was awarded the German Textile Mechanical Engineering 2021 Best Master's Thesis Award for his master's thesis entitled "Modification of the tube weaving process of fine yarns for the production of woven ultra-low profile stent grafts". The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

Minimally invasive endovascular aortic repair (EVAR) with textile stent-graft systems is nowadays a clinically established therapy procedure for the treatment of abdominal aortic aneurysms (AAA) – pathological bulges of the aorta. Due to the thick profile of the folded stent graft systems, there is currently a high risk of injuring narrowed or highly angulated access vessels from the inside during implantation. Stent graft systems with smaller profiles could provide an improvement, which could overcome complicated access routes through a lower bending stiffness. One possible approach for reducing the system profiles is the use of thin-walled tubular woven fabrics made of ultrafine multifilament yarns (≤20 dtex) as graft material.

Up to now, it has not been possible to process the fine yarns with the required high thread density (>200 threads/cm) and the available weaving technology in order to guarantee sufficient tightness against blood.

In his master's thesis, Kai-Chieh Kuo made high-density tubular weaving of ultra-fine filament yarns possible for the first time by means of suitable modifications to a shuttle loom as well as adaptations in the weaving preparation. In particular, he developed a new innovative reed technology that reduces warp thread friction during the shedding process and thus improves the process stability of the dense tube weaving process of fine yarns.

With the help of the process modification, it was then possible to produce high-density, thin-walled tubular woven fabrics, which were positively evaluated with regard to their suitability for a stent graft. Above all the potential of these tubular fabrics lies in their extremely thin-walled fabric profile, which seals well against blood. By using these new types of tubular fabrics as graft material for stent grafts, the system profile of the folded stent graft system can be reduced without having to compromise the blood tightness of the implant. The technology developed by Mr Kuo is not only applicable to stent graft systems, but also offers great possibilities for use in all other endovascular implants such as trans catheter heart valves, covered stents and small-lumen vascular prostheses.
