The "Nonwovens Journey", an immersive experience that takes a look at the innovative role of nonwovens, as well as how innovation has progressed in time around both sustainability, and how nonwovens are used in everyday life, also allowed visitors to discover the versatility of nonwovens.

Running alongside the exhibition itself, there was also a full programme of side events that were enjoyed by participants: Exhibitor Product Presentations from 33 exhibitors; a series of informative seminars covering a myriad of topics including medical nonwovens, sustainability, circular economy, geosynthetics, textiles, mobility, fair trade, gender equity, innovation, and market trends; country-specific briefings offering insights into the nonwovens market in various regions around the world; and a nonwovens tutorial intended as an induction to nonwovens for those new to the industry. These topics were all presented by leading industry experts and guest speakers, including among others, the World Trade Organization (WTO).

Concern for the environment has in recent years become increasingly important, and once again remained a key topic at INDEX™23, with companies pushing to achieve further CO₂ reductions and circularity across the supply chain.

Continuing on from its success during COVID-19, the INDEX™23 Mobile App and Virtual Platform was back. This tool offered participants – both in Geneva and those following from home – the chance to watch presentations live and interact with speakers, exhibitors, and other participants. Attendees were able to plan their visit and organize meetings, which was highly appreciated. Video recordings from the sessions will remain available online in the app and platform for the coming weeks.

The next INDEX™ will take place in three years from 21-24 April 2026.

Freudenberg Performance Materials (Freudenberg) announces the launch of sustainable carpet backing products for the flooring industry. Sustainable backings support customers in their transition towards producing more sustainable carpets. The range is introduced as Colback ECO and Lutradur ECO and is part of the Freudenberg portfolio of high-performance spunbond nonwoven technical textiles.

Reduced CO₂ footprint
Freudenberg follows a ‘less is more’ principle: the best raw materials are the materials that are not needed at all. For the ECO product range, Freudenberg R&D teams developed a solution to save raw materials in their carpet backings. Freudenberg redefined its proprietary yarn production technology allowing for extremely thin filaments with a diameter up to 30% smaller than the standard portfolio for carpet backings.  
The new thin yarn technology is one of Freudenberg’s sustainable initiatives benefitting the carpet industry. Other developments supporting sustainability include backings with a high recycled content and backings using alternative approaches to facilitate carpet recyclability. They will extend the ECO portfolio in the future.

ECO-CHECK-Label
The currently launched thin yarn ECO-backings have been awarded the ECO-CHECK label. Freudenberg introduced this label in early 2021 to identify particularly sustainable products within its portfolio.

Viscose speciality fibre manufacturer Kelheim Fibres, nonwoven producer Sandler, and hygiene product manufacturer pelzGROUP have jointly developed a new panty liner that is plastic-free according to the European Single-Use Plastics Directive (SUPD). This innovative solution is a step towards reducing the amount of plastic in hygiene products – and thus also a contribution to tackling the problem of plastic pollution.

According to a UNEP study on marine litter and microplastics, eight million tons of plastic end up in the oceans every year. A significant portion of this pollution comes from single-use plastic products, including conventional period products such as pads or panty liners.

The partnership between the three companies was formed under the Open Innovation principle, which allowed for creative idea exchange and facilitated the development of an innovative product. According to Jessica Zeitler, R&D Specialist at Sandler, “Our collaboration with Kelheim Fibres and pelzGROUP is a great example of how companies can work together to create solutions that benefit both the environment and consumers. We are proud to be part of this project and the opportunities it offers.”

For hygiene product manufacturer pelzGROUP, it is important to combine sustainability and performance to achieve broad acceptance in the market. “Our panty liner meets the strict requirements of the European Single-Use Plastics Directive (SUPD) while also matching the performance of conventional synthetic products. At the same time, our new panty liner has a completely European supply chain. This means short distances and therefore low CO2 emissions, and – especially in times of global disruption – reliability for our customers,” emphasizes Dr. Henning Röttger, Head of Business Development at pelzGROUP.

"Our viscose speciality fibres are an environmentally friendly and high-performance alternative to synthetic materials," says Dominik Mayer, Project Manager Fibre & Application Development at Kelheim Fibres. "They are at the very beginning of the product value chain and yet have an enormous impact on the functionality of the end product. Open innovation allows us to bring all partners in the value chain to the table, to find the best solution together in a very short time and bring it to commercialisation - the collaboration with Sandler and pelzGROUP is an important milestone in our AHP journey."

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.

Lotus Teknik Tekstil A.Ş., Türkiye, has successfully started up a complete line to produce nonwoven roll goods for biodegradable, plastic-free wet wipes. This line has been delivered, installed, and commissioned by international technology group ANDRITZ.

The neXline wetlace CP line combines the benefits of two technologies: wetlaid and spunlace. Natural fibers are processed gently to create a high-performance and sustainable wipe. This next-generation wipe, called Newipe®, combines the benefits of spunlace fabric, in particular remarkable strength in all directions, with the biodegradability and softness of a WetlaceTM fabric. It is produced with a lower carbon footprint, has a low lint rate, and does not generate dust during production.

Lotus Teknik Tekstil A.Ş. is a leading nonwoven roll good producer and a member of a group company. The group company consists of 4 companies that operate end-to-end manufacturing including nonwovens, cardboard packings, plastics, and finished wet wipe products. Headquartered in Istanbul, Sapro is the leader in Türkiye and one of the four leaders in the manufacturing of wet wipes in Europe. The company produces, converts, and supplies 161 million sheets of wipes per day for personal, household, and industrial use, exporting 70% of its production to 65 countries all over the world. Sustainability plays a prominent role in Sapro’s business strategy.

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.”

International technology group ANDRITZ has delivered, installed, and commissioned a mechanical textile recycling line and an airlay line at Novafiber’s nonwovens production mill in Palín, Guatemala. Both lines have been successfully operating since December 2022.

The recycling line – the second tearing line ANDRITZ supplied to Novafiber – processes post-industrial textile waste from Central America. The recycled fibers feed the latest ANDRITZ Flexiloft airlay line, which produces nonwoven end-products for the bedding and furniture industries – a true example of a circular textile-to-nonwoven approach. The production process ensures complete material use as a state-of-the-art edge trim recycling system returns any waste directly to the tearing and/or airlay line.

This combination of ANDRITZ tearing and airlay lines allows Novafiber to process large amounts of post-industrial garments, controlling the supply chain from raw material to final product. In addition, it enables energy savings and a reduced carbon footprint due to the reduction of shipments.

Based in Palín, Novafiber is a leading company in Guatemala for producing nonwovens from post-industrial textile waste for both the local market and export.

Freudenberg Performance Materials Apparel is expanding its Super Elastic Interlinings Range with the introduction of the apparel industry’s first 100% recycled thermoplastic elastomers (rTPE) base content interlining series. In recognition of the growing use of elastic interlinings in apparel and building on the principles of Freudenberg Performance Materials´ Apparel’s House of Sustainability, these new products speak for high-quality and sustainable solutions.

The new, 100% rTPE base content interlinings are offered in 40-90 g/m2 weights, with wide applicability – from lightweight knit fabrics with applications in leggings and sports bras to elastic woven fabrics that require medium-to-heavy weights, such as denim, maternity clothes, or casual wear. Sustainable without compromising on quality, the new interlinings offer exceptional elasticity and retain excellent recovery capabilities.

The 100% rTPE base content interlinings reduce the need for virgin materials in apparel while also reducing the demand for the extractive practices necessary to produce such materials. Furthermore, the use of recycled components reduces materials in landfills and oceans, in consideration of full-garment lifecycle management.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK will shortly be exhibiting at INDEX 23, the leading nonwovens exhibition in Geneva, 18-21 April.

This modern two-storey development provides state-of-the-art facilities, including enhanced laboratory for client testing and product development.

Resident equipment in the Fibre Development Centre reflects the wide range of fibre extrusion systems offered by FET to clients across the globe and will enable continued growth of the company through innovation.  

Complementing FET’s highly successful meltblown technology, the more recent spunbond range provides unprecedented opportunities for the scaled development of new nonwoven fabrics based on a wide range of fibres and polymers, including bicomponents.

Indorama Ventures Public Company Limited (IVL) and technology specialist Polymateria Limited have signed an exclusive 10-year partnership to help household brands bring biodegradable nonwoven hygiene products to the market through biotransformation technology.

This collaboration provides a new solution for dealing with essential items like facemasks and wipes once they have been used, ensuring they can return safely to nature without leaving behind any microplastics or toxic residue. It is specifically designed to tackle plastic leaking into the environment as unmanaged waste, meaning it is neither collected for landfill nor recycled. Given that most of the plastic in our oceans originates as unmanaged waste on land, addressing the unmanaged waste challenge is key.

IVL’s right to use Polymateria’s unique biotransformation technology for nonwovens supports application in non-virgin resin recycling while providing a solution for ‘fugitive’ used articles, especially those items that end up in the natural environment. This biotransformation process involves the plastic transforming into a bioavailable wax in the open terrestrial environment, whereupon the wax is fully consumed by bacteria, microbes and fungi, leaving just carbon dioxide, water, and biomass. The pulp component is inherently biodegradable under similar conditions.

Nonwovens made by IVL using Polymateria’s technology have been independently tested against, and meet the criteria in, the BSI PAS 9017 standard for the biodegradation of polyolefins in an open-air terrestrial environment published by the British Standards Institution in October 2020. This standard and/or its criteria – the first in the world to ensure plastic can biotransform in the open terrestrial environment without creating any microplastics – is being adopted around the world including in India, Malaysia, the Philippines and Hungary.
