• Biotransformation technology for nonwovens

Avgol^® has received the prestigious Innovation Award at the RIGHT Hygiene conference in recognition of its collaboration with Polymateria in development of pioneering biotransformation technology for nonwovens.
 
Biotransformation is a unique functionality wherein a conventional nonwoven fabric can be modified to react to certain triggers to then begin a cascade, and importantly a fundamental chemical transformation of the polymer resin into a wax that is readily degraded by natural bacteria, microbes and fungi normally found in the environment.
 
“The transformation is triggered through the combined effects of the natural elements of decay - air, moisture, heat and sunlight,” said Mr. Sanjay Bhayani, Director of India Operations with Avgol. “Once triggered, the material will transform into a low molecular weight wax structure leaving no microplastics or toxic residue behind. Moreover, if the product comprising the biotransformation technology is disposed of in the normal way and facilities are available, then it can be recycled by readily available means.”

“By bringing the Biotransformation technology to the various potential markets in India, we hope to offer a real-world solution to waste management,” he said. “We particularly hope to address aspects of the creation of fugitive waste and remove this from the environment without causing additional, and potentially more dangerous, problems.”

The sustainable collaboration and innovation between Indorama Ventures (IVL), Auping and TWE Group presented a certified cradle to cradle process for mattress components across nonwoven applications, at Techtextil, Frankfurt, 21st to 24th June 2022.

Using circular research and design, the industry partnership between IVL Mullagh (Ireland), Auping and TWE Group has resulted in a perpetual, sustainable economic business model, for manufacturers globally. The inclusion of safe raw materials within mattress manufacturing allows the materials to be easily disassembled at the product’s end of use in order to be further reused as same components or recycled into new raw material at the same quality level, to enable versatile textile applications.

Designed for disassembly to optimize the use of existing resources, reduce carbon footprint and support customer objectives all along their customers’ supply chain. This circular industry collaboration begins with design, where the mattress is constructed using only two different base materials, 100% PET polyester textiles and steel wire pocket springs connected with Niaga®️, a non toxic reversible adhesive, making the mattress easy to disassemble and recover.

IVL, Auping and TWE’s shared vision for a better world is demonstrated through their connected and innovative circularity that helps to close the loop. Auping collects, sorts and separates the collected fabrics, which then go to IVL Mullagh for processing, melting and extrusion to form polyester staple fiber. These staple fibers are then converted by TWE Group into nonwovens for use in Auping’s Evolve mattress, a fully circular mattress. Following the end of mattress use, the material recovery process simply starts again.

Auping estimates that annually more than 40 million mattresses are disposed of in Europe alone, the majority of which are incinerated. Their take back system in the Netherlands ensures that when their new mattress is delivered, the old mattress is retrieved and recycled, irrespective of the brand, ensuring existing materials are continually optimized, diverted from landfill and kept in use to achieve a circular economy.

Billi London is shaping the future of fashion with eco legwear. Founded by Sophie Billi-Hardwick and Marie Bouhier in November 2020, the pair’s goal was to create durable and comfortable hosiery that was no longer seen as disposable or for single-use.
 
Each piece is made with innovative enhanced degradable yarns Amni Soul Eco® nylon and ROICA ™ V550 elastane. Amni Soul Eco® is degrading in a time of 5 years*, 20x faster than the normal 40–100-year timeframe. The materials break down into biomass and biogas, create renewable energy and do not leave behind microplastics in landfill. The soft yet chic fabrics have revolutionised the legwear industry as well as pioneering a change across the fashion sector which rarely goes beyond just using recyclable materials.

This year, Billi London was selected as one of only five brands to present as an Organic Exhibitor at the Salon International de la Lingerie (SIL) from 18-20 June at Porte de Versailles in Paris.

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

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

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

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

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

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

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

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

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

The launch is scheduled for the first of May.

Microplastic pollution is a global challenge across many industries and sectors – one of critical importance being textiles.

A 2021 study by the California Ocean Science Trust and a group of interdisciplinary scientists acknowledges that microfibres from textiles are among the most common microplastic materials found in the marine environment. Every time synthetic clothes are manufactured, worn, washed, or disposed of, they release microplastics into terrestrial and marine environments, including human food chains. Synthetic fibres represent over two-thirds (69%) of all materials used in textiles, a proportion that is expected to rise to 73% by 2030. The production of synthetic fibres has fuelled a 40-year trend of increased per capita clothing consumption.

Global textile consumption has become:

• more reliant on non-renewable resources,
• less biodegradable, and
• increasingly prone to releasing microplastics.

The increased consumption is also discretionary, driven by consumer desire and remains unchecked. Thus, the long-term trend in the textile industry parallels the intentional addition of microplastics to products such as cosmetics. The contrast is that the European Chemicals Agency (ECHA) has recommended such intentional additions be restricted, whereas the over-consumption of synthetic fibres continues unchecked. One way for the EU to account for and mitigate microplastic pollution is through an EU-backed methodology measuring and reporting microplastic emissions, so that consumers and procurement officers have the information needed to minimise microplastic pollution resulting from their purchasing decisions.

There is a critical opportunity to address microplastic pollution in the fashion textile industry through the EU Product Environmental Footprint (PEF) methodology. To meet the environmental objectives of the Circular Economy Action Plan, the EU is proposing that companies substantiate their products’ environmental credentials using this harmonised methodology. However, microplastic pollution is not accounted for in the PEF methodology. This omission has the effect of assigning a zero score to microplastic pollution and would undermine the efforts of the European Green Deal, which aim “to address the unintentional release of microplastics in the environment.”

The incorporation of microplastic pollution as an indicator would increase the legitimacy of the PEF method as well as better inform consumer purchasing decisions, especially as the European Green Deal seeks to “further develop and harmonise methods for measuring unintentionally released microplastics, especially from tyres and textiles, and delivering harmonised data on microplastics concentrations in seawater.”

Whilst we continue to learn about the damage of microplastics and there is new knowledge emerging on the toxic impacts along the food chain, there is sufficient information on the rate of microplastic leakage into the environment to implement a basic, inventory level indicator in the PEF now. This is consistent with the recommendations of a review of microplastic pollution originating from the life cycle of apparel and home textiles. There are precedents in PEF for basic level (e.g., ‘resource use, fossils’) and largely untested (e.g. land occupation and toxicity indicators) indicators, and therefore an opportunity for the EU to promote research and development in the measurement and modelling of microplastic pollution by including such emissions in the PEF methodology. For such an indicator, the long and complex supply chains of the apparel and footwear industry would be a test case with high-impact and a global reach.

On 21st October the Managing Director of Officina+39 Andrea Venier has joined a panel discussion in the prestigious arena of the Kingpins24 Digital Show. He contributed to the discussion with his and Officina+39’s point of view on “Water Conservation”, together with Emrah Özkorkmaz from Bregla and Taimur Malik from Stylers International, with Edward Hertzman from Sourcing Journal & Rivet as moderator.

Water crisis remains one of the top issues for humanity and 90% of the world's natural disasters are related to water. Officina+39 has been working hard to rethink the way water is used throughout the denim processes: Andrea's contribution emphasized the company’s practical and consolidated experience in this field, as in recent years their main objective has been to drastically reduce water use in line with UN SDG6.

Andrea pointed out how “fashion industry is still currently deeply rooted in a linear approach: make, use, dispose.” Accordingly to Andrea and Officina+39, the fashion world is becoming aware of this reality and is trying to reinvent itself in order to decrease the use of this precious resource and its negative impacts but there is still work to do in order to redesign a better sustainable model, where circularity should represent the new sustainability: circularity not only when it comes to the materials, but also to water.

In the textile industry water is used as the vehicle for colors and chemical auxiliaries but luckily today many technologies aim at significantly reducing water consumption. Officina+39 is really focused on this target: Andrea explained that “Officina+39 has developed the AQUALESS MISSION, a process suitable for conventional machines that leads to a 75% reduction of the water typically used in denim and garment laundry processes, using a waterless technology and saving costs for producers.”

Despite the start-up cost of investing in the development of sustainable technologies may discourage some in the industry, it is about time to realize that these actions cannot be delayed and that we will increasingly hear about water scarcity, water stress and water risk.

Andrea stated: “It is necessary to develop water management strategies and systems in any company: today there is ISO 14000 related to environmental management, but I believe that governments, brands and related organisations should think about an ISO related just to water management. In this way, every company can understand how much value can be generated in the medium-term and how much money could be saved by investing in this kind of technologies. To create new standards related to water management, we must change the approach.”

• The success story of cellulose fibres continues - plastic bans drive innovation – 300 participants and 30 exhibitors are expected in-person and online
• 2-3 February, Cologne (Germany), hybrid event

Cellulose fibres are among the winners of the European 'Single-Use Plastics Directive (SUPD)', which has been in effect since July 2021 and entails plastic bans for a variety of single-use products. Cellulose is the main component of plant cell walls and a natural polymer. As a result, disposable products made of cellulose and cellulose fibres are not labelled as plastic and are explicitly excluded from the regulation. The success story of cellulose fibres will thus continue at a rapid pace with new developments and applications. Building on the success of this year's conference with 200 participants, the International Conference on Cellulose Fibres 2022 will again cover the entire value chain, from lignocellulose, chemical pulp, cellulose fibres such as rayon, viscose, modal or lyocell and new developments to a wide range of applications: Textiles of all kinds, nonwovens such as wet wipes and new areas such as composites or nanocellulose in the food industry. All these sectors have gained considerable momentum in recent years.

Cellulose fibres have been a success story within the textile market with a compound annual growth rate (CAGR) between 5 and 10 % over the last ten years and similar growth rates are expected in the coming decade. This makes cellulosic fibres the fastest growing fibre group in the textile industry and also the largest investment sector in the global bioeconomy.  The challenge now is to achieve a balance between the ongoing capacity expansion and the growing demand, to avoid overcapacity while still meeting rising demand from the major brands. These high growth rates are driven by the increased demand for natural fibres (and bottlenecks in cotton production), the microplastic issues, and bans on plastics in disposable applications. All three factors will continue to play an important role in the development of the sector in the future.

Focus of the conference

• Impact of plastic-bans on single-use products
• Transformation from fossil to renewable raw materials
• Challenges in developing new value chains
• Alternative raw materials for cellulose fibres
• Latest technology and market trends

• Excellent project to encourage ingenuity among young students
• Experiment on biodegradability of textiles and nonwovens produces impressive results
• EUR 30,000 in prize money for a total of 209 participating schools in and outside Austria
• Lenzing views supporting these kinds of projects as part of its sustainability mission

Lenzing – The Association of Chemistry Teachers in Austria – known by its German abbreviation, VCÖ – has been holding project competitions that thrill students and take them beyond the traditional syllabus for 30 years. Every two years, it highlights a key topic for ninth- and tenth-graders to explore by conducting special experiments and learning from their observations and conclusions.

This year, the 16th installment of the competition is called, “Achieving a cleaner climate and a circular economy with chemistry”. These topics are also near and dear to the heart of globally active fiber manufacturer Lenzing. That’s why the company promptly announced that it was prepared to support this project competition in several different ways. First, Lenzing made a contribution toward the sponsorship fund totaling EUR 30,000. Second, it initiated a special prize on biodegradability – a topic of growing importance given the huge challenges involved in reducing plastic waste. Finally, Lenzing placed a recognized expert at the students’ disposal to provide assistance and answer questions: Michaela Kogler, Project Manager Nonwovens & Technical Products.

Teaming up with rainworms

Two teams were tasked with biodegrading different fibers – just like those used to produce textiles and nonwovens – with the active participation of worms. Students at BRG solarCity in Linz buried fiber nonwovens, a basic material used in wet wipes and other products, in soil that was populated with numerous rainworms, while students at Vöcklabruck Junior High School for Sports and Integration layered textiles into a vermicomposting bin. Both experiments intended to determine the extent to which certain materials would biodegrade quickly. As it turned out, both projects showed that wood-based fibers, like those that Lenzing manufactures for the textile and nonwoven industry, break down very rapidly into natural constituents that swiftly pass into the soil. In contrast, fossil-based plastics such as polyester or polyethylene cannot be decomposed by worms or bacteria but remain in the soil, sometimes for hundreds of years.

The prizes for this year’s competition were awarded on June 11. The competition attracted entries from no fewer than 209 schools, including 11 from outside Austria. For more information on the projects and the winners, visit www.vcoe.or.at.
