From the Sector

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.

Comber machines from Trützschler are already trusted by customers across the textiles industry and around the globe. The TCO 21 is the latest addition to their portfolio and was built to boost productivity,  ensure quality and support increased automation.

High productivity and raw material savings
One of the key benefits of the TCO 21 is its advanced processing speed. This next-generation combing machine is able to produce at a rate of up to 600 nips per minute. the TCO 21 can also be coordinated with Trützschler’s JUMBO CANS (Ø 1.200 mm). They not only reduce yarn defects due to fewer piecings which leads to quality improvements, but also offer a higher efficiency because of their larger dimensions. This, for example, has positive effects on the number of necessary cans and can transports – and results in lower personnel costs.

Excellent yarn quality
The TCO 21 comes with COUNT MONITORING as standard. This feature makes it possible for the machine operator to define limits for count variations via an easy-to-use display. Trützschler’s DISC MONITOR system of sensors measures the count continuously, and the machine alerts the operator and switches off if the limit is exceeded. In addition, the COUNT MONITORING function also includes spectrogram analysis.

Customers can further strengthen their focus on quality by choosing to add the COUNT CONTROL function to the TCO 21. It is managed via the same easy-to-use display, and offers automatic sliver count measurement, as well as spectrogram analysis. It also automatically regulates the main draft during production to balance count variations and ensure the desired sliver count. This feature is particularly attractive for customers who manufacture blends of cotton and synthetic, as it can also be used to avoid variations in the overall yarn composition.

Automatic optimization
The TCO 21 joins the TCO 12 from Trützschler as an combing machine that offers automatic PIECING OPTIMIZER technology, and that finds the right piecing setting without a single laboratory test, because of two functions: First by adjusting the piecing time in the combing cycle (timing function). Whereas the resetting of the detaching point (piecing time) is usually a very time-consuming task, it now takes only a few minutes and is performed automatically at a push on a button. Second the customer is helped to select specific detaching curve types (curve function) for their unique requirements.

Easy operation
The TCO 21 is simple to operate and maintain. The SMART TOUCH display is fast and intuitive, and a Radio-Frequency Identification (RFID) sensor quickly identifies each user and adapts the information on the display to their individual needs. The multi-colored T-LED display provides visual indications of the machine’s status or quality parameters over large distances which enables the operator recognizing them at a glance in the entire spinning mill. The TCO 21 is built with original Trützschler electronics that ensure high performance and durability: Their intelligent cooling system, that has already proven itself in the draw frame TD 10, contributes to a longer service life by reducing the operating temperature of electronic power components. Even if components have to be replaced at some point, the customer can keep their spare parts inventory small, because they can switch also electronics spare parts flexibly between different machine types, e.g. cards and draw frames. The option to add an automatic greasing function completes the easy operation of the TCO 21.

• Results of experiments conducted by the University of California’s prestigious Scripps Institution of Oceanography in San Diego provide further scientific proof that LENZING™ fibers offer an effective substitute to synthetic fibers that are part of the pressing problem of plastic pollution in our oceans.

Lenzing/San Diego – The Lenzing Group, a world-leading provider of wood-based specialty fibers, has received further scientific proof of the biodegradability of its fibers. In a study published in October 2021 , scientists from the prestigious academic research institute Scripps Institution of Oceanography (SIO) at the University of California, San Diego confirmed that wood-based cellulosic fibers biodegrade in the ocean within a short period of time at the end of their life cycle, making them a better alternative to fossil-based fibers. The research was the result of an independent project trying to understand the “end-of-life” scenarios for textiles and nonwovens discarded in the environment.

SIO has a global reputation for being one of the oldest, largest and most important marine research centers worldwide. In this study, SIO compared the degradation processes of nonwovens made from fossil-based synthetic materials such as polyester with those of cellulosic materials such as Lenzing’s wood-based lyocell, modal and viscose fibers in specific scenarios – under various real oceanic conditions and controlled aquaria conditions. The results of these experiments are striking: while wood-based cellulosic fibers fully biodegraded within 30 days, the fossil-based fibers tested were practically unchanged after more than 200 days.

The biodegradability of LENZING™ fibers was also tested in the laboratory of Organic Waste Systems (OWS) in Belgium – one of the world's leading companies in biodegradability and compostability testing – which showed data confirmed by those found with the real-life measurements at Scripps. The OWS assessment was conducted in accordance with applicable international standards and reflects relevant natural and artificial conditions in which biodegradation can occur. Certificates from the certification organization TÜV Austria show that LENZING™ fibers rapidly biodegrade in all test environments (soil, industrial composting, home composting, fresh water and marine water) within the time frames set by the applicable standards.

Lenzing also welcomes the EU’s targeted measures to combat plastic waste in general, such as those relating to the single-use plastic directive (EU) 2019/9043. In its recently adopted guidelines for implementing the directive, the EU Commission stipulates the specific products that fall under this category, which is a well-needed effort to provide clarity to the EU member states for their joint campaign against environmental pollution from plastic waste. Lenzing’s wood-based, biodegradable cellulosic fibers can be part of a sustainable and innovative solution to this man-made problem that will continue to grow. As of July 2021, the single-use plastic directive sets out standardized labelling requirements for certain products, either on packaging or on the products themselves, which include plastic-based feminine hygiene products and wet wipes for body care or household use. This is a start to tackle the problem: educate the consumer and offer alternative materials with better circularity.

The Hygiene Fibers Group of Indorama Ventures (IVL) came together at the Index Show to present an all-inclusive range of recycled and biodegradable solutions for Hygiene Fiber and Nonwoven applications.

The combination of polymers, technologies, processes and global reach supported by the Hygiene Fibers Group – one of three business segments that make up Indorama Ventures – positions it within the Hygiene industry to meet increasingly challenging market demand for innovative sustainable solutions within the hygiene sector. Across the six brands and companies that make up Hygiene Fibers Group – Auriga, Avgol, FiberVisions, Indorama Asia, Trevira and Wellman International – sustainability and supporting customers to achieve circular objectives is integral to all efforts and fundamental to the ethos of the Hygiene business segment.

At the Index Show, the Hygiene Fibers Group launched CiCLO®, a textile technology which allows polyester and other synthetic materials to biodegrade like natural materials do in wastewater treatment plant sludge, sea water and landfill conditions, reducing synthetic microfiber pollution generated during washing, and minimizing plastic accumulation in landfills caused by discarded textiles.

In line with the company’s commitment to support customers with high performance products, while also reducing the impact on the environment, several of the  Hygiene Fibers brands, including Wellman International, Trevira GMBH and Auriga, have been working closely over the last 12 months with the IAM team and the CiCLO® technology. Developments have focused on PET and rPET staple fiber and filament sustainable solutions for applications where recycling is particularly challenging, such as Hygiene, Home Textiles and Automotive applications.

Strengthening the profile of biodegradable offerings within the Hygiene Fibers Group’s sustainability portfolio, Trevira introduced a new range of bicomponent fibres based on PLA and PBS (polybutylene succinate) at the Index show. Both biopolymers offer an exceptional technological opportunity in terms of environmental care and sustainability, while delivering optimum performance. Equally to PLA, PBS is recyclable and up to 100% biodegradable under industrial conditions.

Efforts towards supporting customers to achieve circular objectives are a priority within the Hygiene Fibers Group. This is reflected in the recycled fibers expertise deployed across the segment. Four Hygiene Fibers Group brands, IVL Asia, Auriga, Trevira and Wellman International offer an extensive range of 100% recycled, accredited PET fibers, across a multitude of fiber and nonwovens applications.

The development and evolution of sustainable technologies is central to activity across IVL’s Hygiene Fibers Group, with particular focus on sustainable polyolefin solutions. FiberVisions and ES-FIBERVISIONS, leading Polyolefin mono and bico fiber brands and sister company Avgol, have partnered with UK-based Polymateria to commercially harness the innovative ‘biotransformation’ technology pioneered by Polymateria. The patented technology alters the properties of polyolefins to make them biodegradable in a natural process.  Other polyolefin sustainable innovations within the Hygiene Fibers Group were featured at Index include biosurfactant and biocolourant developments being undertaken by the Avgol team with FiberVisons progressing sustainable design solutions, including lightweight, high performance, reduced carbon solutions.

• At this year’s INDEX from October 19th to October 22nd, Truetzschler Nonwovens, Truetzschler Card Clothing and Voith introduce new solutions for manufacturing a broad range of sustainable nonwovens for wipes, hygiene or medical textiles at booth 2327.

Plastic-free initiatives worldwide affect everyone: consumers, product developers, nonwoven producers and finally nonwoven machinery suppliers.

Truetzschler Nonwovens and Voith address the quest for more sustainable and affordable nonwovens in the wipes segment by two proven technologies for manufacturing pulp-based nonwovens. Firstly, WLS (Wet-Laid/Spunlaced) lines. More than a handful are in service worldwide and mainly target the flushable wipes market. At INDEX we’ll introduce our latest nextLevel/WLS baby and body wipes, a joint development by Voith and Truetzschler.

The second focus is on carded/pulp (CP) products. A CP line – including a TWF-NCT card placed between the HydroFormer and the AquaJet is already running to full capacity at customer site. Various CP materials, including innovative nextLevel/CP wipes, will be on display at the booth and invite visitors to discuss characteristics, benefits, line concepts and equipment.

When talking sustainable nonwovens, solutions for efficiently manufacturing biodegradable nonwovens from virgin cotton fibers, comber noils and viscose/lyocell fibers must not be missing. Visitors can look forward to directly comparing cotton nonwovens to a broad range of cellulose-based material.

Truetzschler Card Clothing, our in-house competence center with respect to card clothings and comprehensive service, presents its latest development, the Z wire for high-speed roller cards. A new geometry minimizes fiber fly and allows for better carding and more stable web forming.

Not only since 2021 has sustainability been a topic high on society’s agenda. And yet the importance of sustainability for consumers and companies has once again increased sharply as a result of the Corona pandemic, as numerous studies confirm. Then why is it often so difficult to implement this conviction in everyday life? One of the biggest obstacles to sustainable consumer behaviour is the lack of availability of alternatives.

In addition to changing consumer demands, the EU Commission's recent decision on the single-use plastics directive is also prompting many nonwovens manufacturers to look at alternative solutions. Kelheim Fibres is exhibiting at this year's INDEX in Geneva and online with bio-based fibers that offer an alternative to synthetic materials in a wide range of applications. The Bavarians have decades of experience in the nonwovens and hygiene sectors and work on individual customer-specific innovations.

"We want to make it easy for consumers to choose an environmentally friendly option. That’s the case when bio-based solutions offer the same performance as synthetic products," said Matthew North, Commercial Director at Kelheim Fibres." Our fibre technology allows us to create just that: unlike natural fibres, which are available already in fibre form and can only be treated on the surface, we can engineer the properties of our fibres they need for specific applications by specifically intervening in the production process. That way we combine nature - our fibres are made of wood pulp - with performance."

Kelheim's special fibres are made of wood pulp from sustainably managed sources, are produced in Kelheim in an environmentally friendly way and are fully biodegradable at the end of their product life. Kelheim Fibres is the first viscose fibre manufacturer in the world with an EMAS validated Environmental Management System and was awarded a dark green/light green shirt in the most recent Canopy HotButton-Ranking.

• International Conference on Cellulose Fibres 2022, 2-3 February in Cologne, Germany and online – Call for Abstracts and Posters – 300 participants and 30 exhibitors are expected

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.

Companies are now invited to submit presentations as well as their latest developments for the Innovation Award.

Main topics of the conference:

• What is the impact of plastic bans on single-use products?
• The avoidance of microplastics and the transformation from fossil to renewable raw materials?
• What are the biggest challenges in developing new value chains and growing market demand?
• Which alternative raw materials for cellulose fibres are suitable and available?
• What are the latest technology and market trends?
• What are the future market dynamics? Who is active and interested in the cellulose fibre sector?
• What ecosystems and partnerships are needed to promote innovation in line with new market requirements?
• How will the political environment develop in the future?
• How can the sustainability of cellulose fibre production be further improved?
