B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK has strengthened its technical team with the appointment of Dr Jonny Hunter as Research & Development Manager. Hunter brings a wealth of academic credentials to the department, including a Master’s in Medicinal and Biological Chemistry and a PhD in Sustainable Chemistry. This academic background is complemented by over 10 years’ R&D experience in industry, including FMCG and, in particular, medical devices, which encompasses wound care, the medical device manufacturing process and regulatory environment.

FET designs, develops and manufactures extrusion equipment for a wide range of high value textile material applications, so the above research and industrial sectors have great relevance to the company’s focus on the international stage. A significant market for FET’s meltspinning equipment is medical devices, so in-house expertise in this area is a vital commodity. FET is also at the forefront of innovation to promote and develop sustainable fibres, so technical knowhow in sustainability is also essential. In this, Jonny Hunter has considerable experience and has in the past lead a number of innovation projects in sustainable chemistry and management.

This fresh input of knowledge and experience will benefit FET’s customers in their own drive for sustainable innovation in fibre technology. Mark Smith, the previous R&D Manager, is taking a short sabbatical and will be returning in a more strategic role as FET’s Director of Technology, so his continued presence will further contribute to FET’s breadth of technical expertise.

FET has also expanded in a number of other departments to reflect the rapid growth in sales over recent years. Mike Urey is the new Sales Engineer, bringing a wide industrial experience and strengthening all aspects of business development. Three new mechanical and electronic engineers and a new appointment in the design department all combine to take the company forward and sustain growth.

Klaus Steger (64), CEO of ERWO Holding AG (“ERWO Holding”) and Hoftex Group AG (“Hoftex Group”), will step down from the Management Board of both companies at the beginning of 2024 in accordance with internal policies of the family and the company regarding the retirement age. Already on June 30, 2023, ERWO Holding Management Board member Hans-Georg von Schuh will retire as planned. ERWO Holding Management Board member Manfred Heinrich will also leave the Board as planned at this time and will continue to hold his mandate as one of the managing directors in the Südwolle Group together with Stéphane Thouvay and Johannes Rauch.

Steger’s designated successor as CEO of both companies is Manuela Spörl (50), currently CFO of ERWO Holding and also CFO of Hoftex Group. Hoftex Group is a group of medium-sized companies in the textile industry, in which ERWO Holding holds a significant stake. In addition, ERWO Holding acts as the parent company of the Südwolle Group, in which the Group’s worsted yarn activities are bundled.

Spörl has a degree in business administration and has been working for Hoftex Group since 2000. Her professional career began in the Corporate Controlling department, and in 2012 she was appointed as an advisor to the Board of Management. She was granted power of attorney in 2015, followed by appointments as CFO of the Hoftex Group in 2020 and CFO of the ERWO Group in 2022. A search for a successor for Spörl in the position of CFO of the Hoftex Group and, subsequently, of ERWO Holding is currently underway. Until the new CFO takes office, the two members of the Management Board, together with the Supervisory Board, will ensure an orderly transition.

The announced change in the Management Board of ERWO Holding, which acts as the parent company of the Südwolle Group, also ensures continuity at the leading manufacturer of worsted yarns for weaving, circular and flat knitting products in pure wool and wool blends. In the future, the management of Südwolle Group will continue to consist of the longstanding members Manfred Heinrich (Technology, Production & Planning), Johannes Rauch (Finance & Controlling) and Stéphane Thouvay (Sales & Marketing and Product Management & Innovation). Together with the designated board member of the parent company ERWO Holding, they will continue the successful development of the Südwolle Group from a mere supplier to a strategic partner of its customers as well as the growth trend of recent years.

The founding family Steger remains involved in the various supervisory bodies of the group of companies and will continue to work closely with them as the sole shareholder of ERWO Holding.

Die Studentinnen Antonia Dannenberg und Nadine Bullerdiek vom Fachbereich Textil- und Bekleidungstechnik der Hochschule Niederrhein sind von der Wilhelm-Lorch-Stiftung ausgezeichnet worden. Dannenberg erhielt den Preis in der Kategorie Technik für ihre Arbeit „Graphen in alpiner Wintersportbekleidung“, Bullerdiek hatte die Jury mit ihrer englischsprachigen Arbeit „Dyeing of Poly(lactic acid) Fibres for Circular Textile Products“ überzeugen können. Der Preis ist mit 5000 Euro dotiert.

In der Arbeit von Antonia Dannenberg (Betreuende Professor:innen Dr. Robert Groten & Karin Stark) werden unterschiedliche mit Graphen ausgerüstete Polyesterproben hinsichtlich ihrer Wärmeleitfähigkeit untersucht. Graphen ist eine zweidimensionale Kohlenstoffatomschicht mit einzigartigen Eigenschaften. Viele Outdoor-Bekleidungshersteller bringen immer mehr mit Graphen ausgerüstete Produkte auf den Markt. Insbesondere in der alpinen Wintersportbekleidung gewinnt der Werkstoff zunehmend an Bedeutung.

Eingearbeitet in textile Flächen bzw. Bekleidung, soll Graphen diesen die Eigenschaft verleihen, Wärme von erhitzen Stellen der Bekleidung an kühlere Stellen zu leiten. Durch diesen Wärmeausgleich würden Sportler:innen potenziell weniger Energie verbrauchen und wären somit leistungsfähiger. Dannenbergs Arbeit hat sich mit der Frage auseinandergesetzt, ob Graphen tatsächlich zur Optimierung der Wärmeleitfähigkeit der Textilien beitragen.

Die durchgeführte Untersuchung hat gezeigt, dass die Wärme sich im aktuellen Forschungsstadium noch nicht wie gewünscht über das Textil verteilt. Keine Probe wies erkennbare Veränderungen auf. Zum jetzigen Zeitpunkt befindet sich die Übertragung der Eigenschaften von Graphen auf textile Flächen in einem frühen Forschungsstadium. Eine Kommerzialisierung von textilen Graphen-Produkten ist demnach aus Forschungssicht bisher noch nicht ausreichend umsetzbar. Aufgrund des weltweiten Interesses ist aber damit zu rechnen, dass in naher Zukunft das Material alltagstauglich und funktionsoptimierend in Bekleidung integriert werden kann. Antonia Dannenberg rundete ihre technische Arbeit mit einer zusätzlichen Designarbeit zum Thema Sportswear ab.

Nadine Bullerdiek hat sich in ihrer Bachelorarbeit („Dyeing of Poly(lactic acid) Fibres for Circular Textile Products”) mit dem Färben von PLA-Fasern für kreislauffähige textile Produkte auseinandergesetzt (Betreuende Professorin: Dr. Maike Rabe).

PLA-Fasern (engl. poly(lactic acid)) gelten als vielversprechende Alternative zu konventionellen Polyesterfasern. Sie sind biobasiert, recyclingfähig und unter industriellen Bedingungen biologisch abbaubar. Somit eignen sie sich für die Herstellung kreislauffähiger Textilien.

Das Problem: PLA-Fasern sind hydrolyseanfällig, besonders unter alkalischen Bedingungen und hohen Temperaturen. Dies bedeutet, dass es beim Färben im Wasserbad zu einem Festigkeitsverlust der Fasern kommen kann. Die Preisträgerin hat in ihrer Arbeit die Auswirkungen der Färbeparameter Zeit, Temperatur und pH-Wert auf die Festigkeit und Farbintensität eines PLA-Zwirns untersucht. So konnten die idealen Färbebedingungen mit möglichst hoher Farbintensität und möglichst geringem Festigkeitsverlust für das Färben des PLA-Zwirns mit Dispersionsfarbstoffen ermittelt werden. Die Arbeit wurde in Kooperation mit dem niederländischen Start-up Arapaha durchgeführt.

This is how we live up to our claim as the ITA Group: sustainable - digital - individual."

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

• Revenue grows to EUR 623.1 mn – fiber sales recovered over the course of the quarter
• EBITDA and net result for the period down compared with the first quarter of 2022
• Cost reduction program of more than EUR 70 mn being implemented according to plan
• Production of TENCEL™ brand modal fibers successfully launched in China
• Lenzing confirms guidance for 2023

The business performance of the Lenzing Group during the first quarter of 2023 largely reflected market trends. However, after the market environment had deteriorated significantly in the third and fourth quarters of the previous year, signs of recovery emerged during the first quarter in terms of demand as well as raw material and energy costs. Textile fibers recorded moderate but steadily improving demand. Business with fibers for nonwovens and with dissolving wood pulp performed better than expected. Raw material and energy costs were still at an elevated albeit decreasing level.

Outlook
The war in Ukraine and the more restrictive monetary policy pursued by many central banks in order to combat inflation are expected to continue to influence global economic activity. The IMF warns that risks remain elevated overall and forecasts growth of 2.8 and 3 percent for 2023 and 2024 respectively. The currency environment is expected to remain volatile in the regions relevant to Lenzing.

This market environment continues to weigh on the consumer climate and on sentiment in the industries relevant to Lenzing. However, the outlook has brightened somewhat recently.

Demand picked up tangibly after the Chinese New Year. As a consequence, capacity utilization improved and stocks were further reduced both at viscose producers and at downstream stages of the value chain.

In the trend-setting market for cotton, signs are emerging of a further buildup of stocks in the current 2022/23 crop season. Initial forecasts for 2023/24 anticipate a more balanced relationship between supply and demand.

However, despite signs of recovery in both demand and raw material and energy costs, earnings visibility remains limited overall.

Lenzing is fully on track with the implementation of the reorganization and cost reduction program. These and other measures are aimed at positioning Lenzing in the best possible way for the expected market recovery.

Structurally, Lenzing continues to anticipate growth in demand for environmentally responsible fibers for the textile and clothing industry as well as for the hygiene and medical sectors. As a consequence, Lenzing is very well positioned with its “Better Growth” strategy and plans to continue driving growth with specialty fibers as well as its sustainability goals, including the transformation from a linear to a circular economy model.

The successful implementation of the key projects in Thailand and Brazil as well as the investment projects in China and Indonesia will further strengthen Lenzing’s positioning in this respect.

Taking into account the aforementioned factors and assuming a further market recovery in the current financial year, the Lenzing Group continues to expect EBITDA in a range between EUR 320 mn and EUR 420 mn for 2023.

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

Absorbent hygiene products such as diapers, sanitary pads, and incontinence products are an integral part of our daily lives. However, most of these products contain synthetic components and contribute to the global plastic waste problem. The search for alternatives is becoming increasingly urgent. The catch is that only innovations that offer the same performance and reliability as conventional products can be successful in the market. After all, no one wants to compromise in such a sensitive area as personal hygiene.

Kelheim Fibres is currently working on various development projects to design fully biobased AHP (absorbent hygiene product) concepts that do not compromise on performance. In this area, the company continues to focus on its wood-based specialty fibres, which the tampon industry has trusted for decades. However, the requirements for AHP products differ, as each layer must fulfil a specific function.

To meet these requirements, Kelheim Fibres has developed a range of functionalized specialty fibres, including hydrophobic Olea, trilobal Galaxy®, and the hollow fibre Bramante. These specialty fibres ensure optimal results in every layer of the AHP product.

All of Kelheim's fibres are manufactured from 100% wood pulp derived from certified and sustainably managed forests. They are fully biodegradable - microorganisms in soil and seawater ensure that no residues remain.

A current example of such a partner project is the development of a completely bio-based panty liner with the nonwovens manufacturer Sandler and the hygiene products manufacturer pelzGROUP, which is due to be launched on the market shortly.

In addition to new projects in the field of biobased disposable and reusable solutions, Kelheim will also present its tried and tested fibres at INDEX™23, for example for tampons or flushable wipes.

For the period 1 March to 31 March, Renewcell 1 produced approximately 1,150 tonnes of prime quality dissolving pulp (within specification for Circulose®). About 1,300 tonnes were delivered to customers during the period. Total production output at Renewcell 1, including prime quality, was approximately 1,350 tonnes of dissolving pulp during the period.
