• JUMBO-Textil offers elastic high-tech braids – produced on high-tech systems

Developing narrow textile solutions for our customers – quickly, flexibly and precisely – that is our claim. For us and for our technology. Because first-class industrial solutions require first-class technology. Highly automated and digitally controlled. Technology like that found in our variation braider from Herzog – the high-performer among modern braiding machines. JUMBO-Textil is the first narrow textile manufacturer ever to produce elastic hole cords on the special system.

High-performance system for extremely stable textile components
The special system combines sophisticated bobbin lace technology with digital control and thus enables the production of highly complex, individually specifiable braided structures. The variation braider's technology ensures an uninterrupted fibre course across all branches. This not only allows individual, idiosyncratic geometries, it also and above all helps with the stability of the components. This is because where other methods create branching points that are susceptible to breakage due to laser cutting, seams or knots, the variation braider simply braids through the branched strands. As the fibre course is not interrupted in braided branches, the resilience of the textiles is significantly increased. And individual braids are created for very different applications.

Bobbin lace technology for highly complex structures
Unlike in classical braiding systems, the impellers of the variation braider are arranged in a square. Up to eight different strands can be braided and interlaced with the textile all-rounder. All bobbins can be programmed separately and thus the bobbin lanes can be combined variably and individually. JUMBO-Textil also produces tubular braids with precisely defined braided openings, triaxial braids and highly complex preforms with the variation braider. The geometries of the narrow textiles range all the way to net structures. For braided cables, we create stable connections in the core-sheath braiding by weaving the core and the protective sheathing, which provides protection especially at the turns: there is no longer any undesired core and sheath slippage.

Individual braid architectures – for automotive, outdoor and more
Complex non-elastic cords from the variation braider have been in operation at JUMBO-Textil for a long time. For hole cords – or bifurcation cords (from the Latin: furca, the fork) – the bobbin points are individually programmed so that the arrangement and length of the branching precisely meet the requirements. It is used, among others, in the automotive sector, in the construction industry and in the outdoor sector to hang or unhang elements without using metal.

Elastic hole cord from the elastics specialist
The elastic hole braids by JUMBO-Textil are new on the market. "The variation braider offers us fantastic possibilities: we can pre-configure what we want to braid and are completely free to do so. The repeat is computer-controlled," explains Holger Vehring, Project Engineer at JUMBO-Textil. "A seamless braided cable harness tubular that organises the cable mess (for automotive), braided hoses with defined openings for conductive elements in smart textiles or rehab applications, as tensioning elements in backpacks or functional clothing – the possible applications are vast. Thanks to this technology, textile – i.e. lighter, quieter and more flexible – components can be used for numerous applications in which metallic materials were previously used due to the fragile branching points."

Textechno reports launch of a new standard for the drapability and deformability of fabrics and non-wovens: ISO 21765

World market leader for precision testing equipment Textechno and their partner SAERTEX, global market leader in non-crimp fabrics (NCF) are proud to announce that the newly developed international standard ISO 21765:2020 to quantify material behaviour in terms of drapability and deformability was recently published by ISO.

The new standard ISO 21765 allows the world-wide comparable measurement of all relevant parameters regarding the deformability and drapability of all kinds of fabrics, including woven fabrics and NCFs as well as knitted fabrics and non-wovens on Textechno´s precision testing equipment DRAPETEST. This can be very useful in the carbon fibre recycling since one of the most efficient applications of recycled carbon fibres will be in non-wovens.

This is the first testing instrument world-wide to quantify not only the force which is required for deforming a fabric, but also the various defects such as gaps, undulation, or wrinkles which can arise due to the deformation.

In the frame of a publicly funded project which started in 2011, Textechno developed the award-winning automatic drapability tester DRAPETEST along with other partners, amongst them SAERTEX.  

Dietmar Möcke, CTO at SAERTEX says: „With ISO 21765, we finally have a standardized testing method with world-wide validity. It allows us to provide our customers with comparable and reproducible measurement values regarding the draping characteristics of our products.”

Ulrich Mörschel, Managing Director of Textechno adds: “We are grateful for the support from all around the world allowing us to establish the new ISO standard. The standard finally fills a gap in the testing methods for fabrics both in the fields of textiles and composites.”

Dr. Michael Effing, Managing Director of AMAC GmbH and Senior Advisor to Textechno: “A lot of research is dedicated to new production technologies of composites, non-crimp fabrics and classical fabrics for thermosets have with 33 % a significant market share in the production of all composite materials. The application of the new standard for non-wovens from recycled carbon fibres comes perfectly on time for this market sector which will gain more and more importance within the next years.

Fibre Extrusion Technology of Leeds, UK has delivered nine meltspinning systems to clients in the biomedical sector since the onset of the Covid-19 pandemic, with a similar number currently on order for 2021/22. This way FET could confirm the position as an acknowledged world leader in meltspinning equipment for the production of precursor materials used in medical devices and as a default supplier for absorbable suture production systems, with orders virtually doubling year on year.

Recent installations include a multi-functional system that can produce both multifilament and monofilament pre-cursor fibres, but nonwoven systems have been particularly prominent, driven by the burgeoning demand for FFP3 masks, gowns and other medical products required during the pandemic. These have been sold to medical device manufacturing companies across the globe, including the Far East, USA and Europe. Research organisations have also invested in FET systems for biomedical applications, the most recent being the University of Leeds in a laboratory scale Spunbond system.

The FET in-house Process Development Laboratory and ongoing collaboration with biomaterial polymer suppliers has helped to optimise the biomedical melt spinning technology. The Laboratory is at the disposal of customers for all aspects of confidential testing and evaluation. To further increase this competitive edge, FET will be opening a new Process Development Laboratory and Visitor Centre in early 2022.

• Rieter CAMPUS strengthens innovation strategy and technology leadership position
• Customer and technology center and administration building ready for occupancy in 2024
• Commitment to the Winterthur site and to Switzerland as a business location

On September 8, 2021, the foundation stone was laid for the Rieter CAMPUS on the western part of the Rieter site at the Winterthur location, which includes a customer and technology center as well as an administration building. The Rieter CAMPUS will make an important contribution to the implementation of the innovation strategy and to the enhancement of the company’s technology leadership position. At the same time, the investment of around CHF 80 million is a commitment to the Winterthur site and to Switzerland as a business location. 

With a floor area of over 30 000 m2, the Rieter CAMPUS offers space for around   700 ultra-modern workplaces. For this purpose, Rieter and a specialist in office architecture have developed a contemporary space concept for the “Open Space Office” that is tailored to the needs of the company, divided into meeting rooms, focus rooms and some individual offices. The underground car park provides   88 parking spaces, and a further 12 outdoor parking spaces are being created   in front of the technology center.  “In the course of its 225-year company history, Rieter has helped shape the city of Winterthur. The foundation for the future as a leading technology company is now being created with the new CAMPUS. In this way, Rieter is giving a clear indication   of its commitment to the Winterthur site and to Switzerland as a business location”, commented Bernhard Jucker, Chairman of the Board of Directors of Rieter Holding AG.

Innovation is an important part of Rieter’s strategy and crucial for the company’s success. For this reason, Rieter invests more than CHF 50 million annually in research and development. Thanks to this commitment, Rieter is making a   decisive contribution to the further development of systems for sustainable yarn production and their digitization. The Rieter CAMPUS will provide an attractive working environment that promotes creativity and innovation.  The new CAMPUS is a showcase project in terms of economic feasibility, energy efficiency and sustainability. Rieter relies on renewable energy for construction. This includes heat generation via geothermal probes and a photovoltaic system on around 1 300 m2 of roof area. “In this way, the entrepreneurial focus on sustainable and energy-efficient solutions for yarn production is reflected in the overall concept of the CAMPUS,” emphasized Rieter CEO Norbert Klapper.  The move into the new building is planned for 2024.

As one of the driving forces helping to create a fully circular fashion industry, ISKO has partnered with Swedish research and development company MoRe Research, a part of RISE Research Institutes of Sweden, to investigate and develop new, sustainable technologies made from cellulosic-based materials, derived from waste textiles, for the company’s 25,000+ range of products. It is hoped that this research will also help make the production of cellulose-based materials more sustainable.

The work with MoRe Research feeds into ISKO’s Responsible Innovation™ strategy and will link with various sustainability projects the company is working on. For example, ISKO recently signed an agreement with HKRITA to license its Green Machine – a unique technology that fully separates and recycles cotton and polyester blends at scale.

ISKO will leverage MoRe Research!s expertise and resources to find ways of repurposing the clean and toxic-free cellulose powders that are created from the decomposed cotton, as well as the recycled polyester and reintegrate this back into fabric production. By using all of the outputs from the recycling of textiles back into textiles, the prospect of a closed-loop system becomes more feasible.

The investment in this new technology is the latest in ISKO’s ongoing drive for advancements in sustainability. As part of the company’s R-TWO™ program ISKO is also working to develop fabrics with a guaranteed minimum +50% GRS (Global Recycle Standard) recycled content blend. This will significantly reduce the carbon and water footprint of a fabric, as well as make it easy to trace a garment’s sustainable journey step-by-step from the beginning of the supply chain through to the end product.

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, and SABIC, a global leader in the chemical industry, announced a collaboration to create recycled-based Dyneema®. Through a joint pilot with multiple CirculariTeam® members, the manufacturing and usage of Dyneema® using mixed plastic waste as feedstock (via mass balance approach) will be successfully demonstrated. It is an important step toward the future goal of fully closing the loop by delivering Dyneema® made from ultra-high molecular weight polyethylene (UHMwPE) waste. This collaboration underlines DSM’s and SABIC’s efforts to accelerate a circular economy for materials.

By working together with members of CirculariTeam®, DSM will produce recycled-based Dyneema® made using SABIC’s certified circular ethylene as a pilot project in both a sailing rope and a pelagic trawl net application. The circular ethylene, from SABIC’s TRUCIRCLE™ portfolio, uses mixed plastic waste as feedstock (mass balance approach), which not only contributes to preventing valuable plastic from becoming waste and the avoidance of carbon emissions compared to incineration, but it will also help preserve fossil resources. These pilots are an important early-stage milestone in the journey toward making fully circular Dyneema® from HMPE post-production and post-consumer waste.

Jon Mitchell, Managing Director at Marlow Ropes: “We’re proud to be one of the first manufacturers to integrate recycled-based Dyneema® within our products and demonstrate the material’s feasibility. By collaborating with materials science pioneers such as DSM and SABIC, we are able to create products that not only deliver superlative functional performance but also have a lower environmental impact. Our products are trialed and tested by professional offshore sailing teams including 11th Hour Racing Team, a proud partner of ours at Marlow, with whom we share a progressive approach to seeking sustainable solutions: no more business as usual."

Klaus Walther, Managing Director at Gleistein: “Warm congratulations to DSM and SABIC for pushing the boundaries of science to deliver a truly unique product. We’re proud that our ropes can be produced from what once was typical household plastic waste. This is an important stepping stone towards becoming circular. It will enable our customer Maritiem BV to further develop high-tech fishing gear whilst contributing to the circular economy. Not to forget Cornelis Vrolijk Fishing Company, who again illustrate their commitment to Corporate Social Responsibility by introducing this concept in fishery.”

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.

Composites Evolution Ltd has teamed up with leading natural fibre reinforcement specialists Bcomp to launch a new range of flax-epoxy prepreg materials, designed to offer enhanced sustainability without compromising on performance.

Evopreg ampliTex™ prepregs combine Composites Evolution’s high-performance Evopreg epoxy resin systems with Bcomp’s award-winning ampliTex™ flax reinforcements, to deliver a family of materials which offer outstanding performance for component applications.

To reach the full performance of natural fibres, Evopreg ampliTex™ prepregs have been tailored to be compatible with Bcomp’s powerRibs™ reinforcement grid, enabling the same stiffness and weight as thin-walled monolithic carbon fibre parts while decreasing the CO₂ footprint by 85% and improving safety thanks to a blunt braking behaviour without dangerous debris or sharp edges.

Composites Evolution’s Sales & Marketing Director, Ben Hargreaves, explains further.
“Sustainability is an increasingly important factor for many of our customers - particularly those involved in motorsports and high-performance automotive applications. As you’d expect in these sectors though, sustainability can’t come at the expense of performance the two must go hand-in-hand. This is something that other prepreggers can struggle with, as natural fibres behave very differently to carbon or glass, for example.”

Customers would be able to understand the strengths and weaknesses of natural fibre composites, and to show where and how they can be adopted without the need for significant changes to existing composite component production processes.

One such customer is Retrac Group, whose composites division is one of the UK’s most experienced composites engineering companies across motorsports, automotive and aerospace. It recently used Evopreg ampliTex™ + powerRibs™ to produce a demonstrator bonnet panel for a race-bred supercar. Project Manager Alan Purves explains.

“We’re seeing a growing interest in flax fibre composites, particularly in the motorsports and niche vehicle sectors. It is therefore essential that we have developed an in-depth understanding of the processing requirements and performance capabilities of these materials, and are ready to respond to our customers' requirements. Being able to tap into the combined expertise and experience of both Composites Evolution and Bcomp is proving invaluable.”

• Strong operating result: EBITDA at EUR 217.8 mn, cash flow from operating activities at EUR 199.8 mn
• Major strategic projects continue fully on track – production start of the lyocell plant in Thailand in the fourth quarter of 2021
• Start of strategic cooperation agreement for textile recycling with Södra
• New milestones in the implementation of group-wide carbon neutrality: EUR 200 mn investment in existing locations in Asia
• Guidance 2021: Lenzing expects EBITDA of at least EUR 360 mn

The Lenzing Group reported a significant improvement in revenue and earnings in the first half of the year. Growing optimism in the textile and apparel industry and the ongoing recovery in retail caused a substantial increase in demand and prices on the global fiber market, in particular at the beginning of the current financial year.

Revenue rose by 27.5 percent to EUR 1.03 bn in the first half of 2021. This increase is primarily attributable to higher viscose prices, which stood at more than RMB 15,000 in May thanks to significantly higher demand for fibers, especially in Asia. The focus on wood-based specialty fibers such as TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ branded fibers also had a positive impact on the revenue development; the share of specialty fibers in fiber revenue rose to 72.8 percent in the reporting period. The negative impact of more unfavorable currency effects was consequently more than offset.

The earnings development essentially reflects the positive market development and was additionally reinforced by measures to improve efficiency. Energy and logistics costs increased significantly throughout the entire reporting period. EBITDA (earnings before interest, tax, depreciation and amortization) more than doubled and amounted to EUR 217.8 mn in the first half of 2021 (compared to EUR 95.6 mn in the first half of 2020). The EBITDA margin rose from 11.8 percent to 21.1 percent. Net profit for the period amounted to EUR 96.1 mn (compared to a net loss of EUR minus 14.4 mn in the first half of 2020) and earnings per share to EUR 3.06 (compared to EUR 0.06 in the first half of 2020).

“Lenzing had a very strong first half-year. The demand for our sustainably produced specialty fibers once again developed excellently,” says Stefan Doboczky, CEO of the Lenzing Group.

Fibre Extrusion Technology Ltd, UK has completed the installation and commissioning of a new FET Laboratory Spunbond system for the University of Leeds.

This FET spunbond system is now an integral part of the research facilities of the CCTMIH (Clothworkers’ Centre for Textile Materials Innovation for Healthcare), led by Prof. Stephen Russell based in the School of Design, University of Leeds, who commented “The new spunbond system is perfectly suited to our academic research work, and is already proving itself to be extremely versatile and intuitive to use”.
 
This spunbond system complements existing research lab facilities at the university, which covers all areas of fibre and fabric processing, physical testing and characterisation. It forms part of a wider investment in facilities to support fundamental, academic research on ‘future manufacturing’ for medical devices, where the focus is on studying small-scale processing of unconventional polymers and additive mixes to form spunbond fabrics with multifunctional properties.
 
Key to this research is developing the underlying process-structure-performance relationships, based on the measured data, to provide detailed understanding of how final fabric performance can be controlled during processing.

As a rule, many exciting materials developed in academic research struggle to progress beyond the bench, because of compatibility issues with key manufacturing processes such as spunbond. By leveraging mono, core-sheath and island-in-the-sea bicomponent technology, the Leeds University team is working with polymer and biomaterial research scientists, engineers and clinicians to explore the incorporation of unusual materials in spunbond fabrics, potentially widening applications.
 
FET has built on its melt spinning expertise to develop a true laboratory scale spunbond system and is currently working on a number of other such projects globally with research institutions and manufacturers.
