From the Sector

More than 82 companies, businesses and social organizations – including AkzoNobel – are involved in a major Dutch research program focused on developing new technologies that will help solve some of today’s societal challenges.
 
Seven broad consortia have been established as part of the government-funded “Perspectief” program, with AkzoNobel set to play a leading role in the SusInkCoat project, which will explore how to make inks and coatings more sustainable.

The company will work together with private partners and other societal stakeholders to develop new materials, processes and applications to improve the durability, functionality and recyclability of coatings, thin films and inks. The program, which will run for the next five years, is backed by the Ministry of Economic Affairs and Climate Policy and the Dutch Research Council (NWO).

“Our discussions about collaborating with our SusInkCoat partners have been very positive,” says AkzoNobel’s R&D Director of Scientific Academic Programs, André van Linden, who is also the co-lead of SusInkCoat. “We’re all facing the same societal challenges – how to become more circular – and we’re looking for the same solutions in different application areas. But we’ve never done that together for this specific research topic, so we need an ecosystem to help us solve these challenges.
 
Van Linden adds that the program – one of many R&D projects the company is involved with – will also support AkzoNobel’s ambition to achieve 50% less carbon emissions in its own operations – and across the value chain – by 2030.
 
 “We want to make the recyclability of materials - such as furniture, building materials and steel constructions - easier by introducing functionalities like self-healing, higher durability and triggered release,” he continues. “The more you can leave the materials in their original state, the more sustainably you can operate.”

AkzoNobel will be collaborating with Canon, Evonik, GFB, PTG and RUG Ventures, who together possess extensive knowledge of market demands, supply chains and production processes. All the SusInkCoat partners will also work with academic researchers at several Dutch universities in an effort to identify promising developments that can be commercialized, used for education purposes or for outreach to the public.

Research being conducted by the other six consortia includes investigating methods to make tastier plant-based food; flat optics for more sustainable hi-tech equipment; and cheaper and more accessible medical imaging technology.

The Dutch company Knitwear Lab helps visions become reality. The creative think tank offers capacities in the areas of R&D, design, knitwear development and production of prototypes and small quantities and has thus implemented a wide range of projects in recent years. The objects range from medical products and high-tech sportswear to smart textiles with integrated sensors. Sustainability activities are also part of the repertoire, such as the production of yarns from recycled waste.

Knitwear Lab operates at two locations for its diverse tasks: Almere in the Netherlandsis available for development work. In Istanbul, there is a branch for production. Both Knitwear Lab sites each have five STOLL flat knitting machines, including models from the modern ADF range. Prototypes are produced in Almere and there is small-scale production. The production plant in Istanbul specializes in the manufacture of high-quality knitwear in small quantities. STOLL is also involved in the creative processes. For the industrial development of knitwear, Knitwear Lab offers Virtual Knitting, a revolutionary method that combines virtual and physical elements of pattern development and knitwear production to reduce waste and pre-production steps. Customers can use Virtual Knitting to create realistic, producible collections, simplify their design iteration processes and take advantage of the wide range of real-life colorways. The basis for this is comprehensive knitwear expertise, the latest 3D software and the CREATE PLUS patterning software, which was developed by STOLL together with KM.ON.

"The 3D visualization of CREATE simplifies communication with the customer considerably. We use this function every day," says Annika Klaas, Senior Knitwear Programmer. She personally appreciates the uncomplicated grading and exchange of stitch dimensions and the much faster and more efficient work with Dimensioned Shapes that this makes possible. This helps her in her day-to-day work. "We often have requests to realize the same product in different yarns, which now works much faster," says the programmer. Further simplifications would include minor optimizations in terms of the efficiency and user-friendliness of programming and additional import and export options for shapes. Discussions on implementation are already underway.

After four decades in the packaging industry, the Manjushree Group is entering the Indian nonwovens market. The entrepreneurs rely on a flexible RF Smart Composite line from Reifenhäuser Reicofil to meet very different customer requirements.

The Manjushree Group operated a blown film line for packaging materials for the tea industry in the eastern part of India as early as 1983. In the years that followed, Manjushree Technopack Ltd. developed into one of the largest suppliers of solutions for rigid plastic products in South Asia - and the family business grew into a group with several business segments. In 2018, the entrepreneurial family repositioned itself: it sold its previous core business to a financial investor and established Manjushree Ventures with footholds in start-up financing, real estate business, and manufacturing - the largest of which is Manjushree Spntek as a producer of high-quality spunmelted fabrics.

Since February 2023, Manjushree Spntek has been producing high-performance spunmelts on an RF Smart Composite line from Reifenhäuser Reicofil - benefiting both from many years of experience in the packaging industry and from experience with Reifenhäuser's blown film lines. "We know a lot about plastic extrusion, for example when it comes to line operating parameters such as temperature and pressure. Processing is similar in both industries," explains Rajat Kedia. "The main difference is the distribution of the products: In plastic packaging, we had an established customer base and sold a lot of material to the big consumer goods manufacturers. The nonwovens market in India, on the other hand, is still forming, with thousands of small companies currently getting involved." These serve customers in their regions, such as hospitals.

The RF Smart Composite line is a standardized spunmelt line for smaller and emerging markets. The line produces nonwovens of the highest Reicofil quality with appropriately adapted throughput. This makes it ideally suited for applications in hygiene and medical technology and, with typically 8,200 annual production hours, it is extremely reliable. In addition, operators can start production quickly because in many cases the line can be integrated into existing buildings.

Before production could start, Manjushree built a new production building in Bidadi, a town an hour's drive from Bangalore International Airport. The building is designed to be sustainable: It uses natural light and fresh air, has comprehensive contamination control, and obtains almost all of its energy from renewable sources. Reifenhäuser Reicofil then installed, commissioned and tested the RF Smart Composite line.

Since February 2023, Manjushree Spntek has been producing high-quality spunmelted nonwovens, including ultra-soft fabrics and fabrics with special coatings for customers in the hygiene and medical industries. The material can be used, for example, for baby diapers and feminine hygiene products, but also for medical articles ranging from surgical gowns to surgical drapes.

• Revenue of EUR 1.25 bn and EBITDA of EUR 136.5 mn in the first half of 2023
• EBITDA and net result for the period significantly improved compared with the first quarter of 2023
• Cost-cutting program and measures to strengthen sales activities being implemented as planned
• Liquidity position strengthened by successful capital increase and extension of credit terms
• Production of TENCEL™ brand modal fibers successfully launched in China

The business performance of the Lenzing Group, a leading global supplier of specialty fibers for the textile and nonwoven industries, largely reflected the subdued market trends in the first half of 2023. After the market environment deteriorated significantly in the second half of 2022, signs of recovery were evident during the first and second quarters of 2023 in terms of both raw material and energy costs as well as demand. Textile fibers recorded improving demand, and business with nonwoven fibers and with dissolving wood pulp proved to be very stable.

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 3 percent for both 2023 and 2024. The currency environment is expected to remain volatile in the regions of relevance to Lenzing.

This market environment continues to weigh on the consumer climate and on sentiment in the industries relevant to Lenzing. Recently, however, the outlook brightened somewhat according to a global survey by the ITMF.*

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 also see a further buildup of stocks in 2023/24, albeit to a lesser extent.

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 its reorganization and cost-cutting program. These and further measures are aimed at positioning Lenzing in the best possible way for the expected market recovery.

In structural terms, Lenzing continues to anticipate growth in demand for environmentally responsible fibers for the textile and clothing industry as well as 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 consideration 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.

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.

• 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.

The diabetic community has always been a priority for Hologenix, creators of CELLIANT® infrared technology, so the company embarked on an initial study to test the hypothesis that the technology can positively impact diabetic patients with vascular impairment, now published in Journal of Textile Science & Engineering. Another study is underway as well with more research on the horizon.

According to statistics cited in the International Diabetes Federation Diabetes Atlas, 9th edition, globally, close to a half billion people are living with diabetes and that number is expected to increase by more than 50 percent in the next 25 years.
 
The introduction of the study in the Journal of Textile Science & Engineering also reports that diabetic patients frequently suffer from a combination of peripheral neuropathy and peripheral artery disease, which particularly affects their feet. It further states that it has been estimated that the lifetime risk for the development of foot ulcers in diabetic patients can be as high as 25 percent and that the risk of amputation is 10 to 20 times higher than in non-diabetic subjects.
 
The study was performed by Lawrence A. Lavery, D.P.M., M.P.H., a Professor in the Department of Plastic Surgery at UT Southwestern Medical Center. His clinic and research interests involve diabetic foot complications, infections and wound healing, and he participated in the conception, design, implementation and authorship of the Journal of Textile Science & Engineering study.  

CELLIANT technology is a patented process for adding micron-sized thermo-responsive mineral particles to fibers, in this case polyethylene terephthalate (PET) fibers. The resulting CELLIANT yarns were woven into stockings and gloves containing either 82% CELLIANT polyester, 13% nylon and 5% spandex or for the placebo, 82% polyester with no CELLIANT, 13% nylon and 5% spandex. CELLIANT products absorb body heat and re-emit the energy back to the body as infrared energy, which is non-invasive and increases temporary blood flow and cell oxygenation levels in the body.

The objective of the study was to “evaluate changes in transcutaneous oxygen (TcPO2) and peripheral blood flow (laser Doppler, LD) in the hands and feet of diabetic patients with vascular impairment when CELLIANT gloves and stockings are worn.” While there was not a statistically significant result across all subjects, the study did show that some patients wearing CELLIANT stockings for 60 minutes had an increase of as much as 20% in tissue oxygenation and 30% in localized blood flow. According to the study’s conclusion, “the trends that were observed in favor of CELLIANT stockings suggest that a larger well-designed clinical trial should be undertaken and may provide evidence of clinical efficacy in treatment of the diabetic foot.”
 
The study also notes that “There have been no documented or observed side effects of wearing CELLIANT stockings, and they are relatively inexpensive compared to conventional pharmaceutical interventions.”

Hologenix has embarked on a more comprehensive trial, “Study to Evaluate CELLIANT Diabetic Medical Socks to Increase Tissue Oxygenation and Incidence of Complete Wound Closure in Diabetic Foot Wounds” – NCT04709419, which focuses on the impact of CELLIANT technology to potentially improve tissue oxygenation and wound healing outcomes.
 
“We are excited to explore whether future studies of infrared, with its most common biological effects of increased localized blood flow and cellular oxygenation, could result in a breakthrough in diabetic patients with vascular impairment,” said Seth Casden, Hologenix Co-founder and CEO. “We see a huge potential opportunity with this research for helping to fulfill our core mission of improving people’s health and well-being by potentially reducing the impact of diabetes, and we are actively seeking partners to expand our research efforts.”

• Revenue rose to EUR 2.57 bn, while EBITDA declined to EUR 241.9 mn
• Implementation of EUR 70 mn cost reduction program proceeding according to plan
• Largest investment program in the company’s history including the lyocell plant in Thailand and the pulp mill in Brazil implemented on time and within budget
• Outlook: Lenzing expects EBITDA in 2023 to be in a range of EUR 320 mn to EUR 420 mn

The Lenzing Group was increasingly affected by extreme developments on the global energy and raw material markets in the 2022 financial year, in tandem with most of manufacturing industry in Europe. The market environment also deteriorated significantly in the third and fourth quarters, while worsening consumer sentiment placed an additional burden on Lenzing’s business growth.

In the year under review, revenue increased by 16.9 percent year-on-year to reach EUR 2.57 bn, primarily as a result of higher fiber prices. The quantity of fiber sold decreased, while the quantity of pulp sold rose. In addition to lower demand, the earnings trend particularly reflects the increase in energy and raw material costs. Earnings before interest, tax, depreciation and amortization (EBITDA) decreased by 33.3 percent year-on-year to EUR 241.9 mn in 2022. The net result for the year was minus EUR 37.2 mn (compared with EUR 127.7 mn in the 2021 financial year), while earnings per share stood at minus EUR 2.75 (compared with EUR 4.16 in the 2021 financial year).

Outlook
The war in Ukraine and the tighter monetary policy pursued by many central banks to combat inflation will continue to exert pressure on the global economy. The easing of China’s zero-Covid policy could lead to an unexpectedly rapid recovery. However, the IMF has warned that risks remain high overall and projects growth of 2.9 percent in 2023. Exchange rate volatility looks set to continue in regions that are important to Lenzing.

These challenging market conditions are also continuing to weigh on consumer confidence and sentiment in the sectors relevant to Lenzing. The outlook has improved slightly of late, with inventory levels returning to normal across the value chain. Nonetheless, subdued demand remains a source of concern for market players.

Inventories in the bellwether cotton market have diminished recently, although they remain above pre-pandemic levels. A decline in crops is foreseeable in the current 2022/2023 harvest season. The sharp rise in prices on the energy and raw material markets will continue to pose significant challenges for the market.

Overall, earnings visibility remains restricted.

In structural terms, Lenzing expects a continued rise in demand for environmentally friendly fibers in the textile and clothing industry, as well as in the hygiene and medical sectors. Thus, with its “Better Growth” strategy, Lenzing is very well positioned and will continue to drive growth in specialty products, while pursuing its sustainability targets including the transformation from a linear to a circular economy model.

In light of these factors and assuming a further market recovery in the current financial year, the Lenzing Group expects EBITDA in 2023 to be in a range of EUR 320 mn to EUR 420 mn.

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

Fibre Extrusion Technology Limited (FET) of Leeds, England has installed a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research to support sustainable growth and development.

This research programme will be conducted by The Henry Royce Institute, which operates as a hub model at The University of Manchester with spokes at other leading research universities in the UK.

The Henry Royce Institute identifies challenges and stimulates innovation in advanced UK materials research, delivering positive economic and societal impact. In particular, this materials research initiative is focused on supporting and promoting all forms of sustainable growth and development.
These challenges range from biomedical devices through to plastics sustainability and energy-efficient devices; hence supporting key national targets such as the UK’s zero-carbon 2050 target.

FET-200 Series wet spinning systems complement FET’s renowned range of melt spinning equipment. The FET-200LAB is a laboratory scale system, which is especially suitable for the early stages of formulation and process development. It is used for processing new functional textile materials in a variety of solvent and polymer combinations.

In particular, the FET-200LAB will be utilised in trials for a family of fibres made from wood pulp, a sustainable resource rather than the usual fossil fuels. Bio-based polymers are produced from biomass feedstocks such as cellulose and are commonly used in the manufacture of high end apparel. The key to cellulose and other materials like lyocell and viscose is that they can be recycled, treated and fed back into the wet spinning system for repeat manufacture.

Established in 1998, FET is a leading supplier of laboratory and pilot melt spinning systems with installations in over 35 countries and has now successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.
