The innovations will be presented by the companies on the first day of the event. All conference participants can vote for one of the six nominees and the top three winners will be honoured with the “Cellulose Fibre Innovation of the Year” award. The Innovation award is sponsored by GIG Karasek (AT).

In addition, the ever-growing sectors of cellulose-based nonwovens, packaging and hygiene products offer conference participants insights beyond the horizon of traditional textile applications. Sustainability and other topics such as fibre-to-fibre recycling and alternative fibre sources are the key topics of the Cellulose Fibres Conference, held in Cologne, Germany, on 13 and 14 March 2024 and online. The conference will showcase the most successful cellulose-based solutions currently on the market or those planned for the near future.

The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry – Honext Material (ES)
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, it is verified in the Product Environmental Footprint.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

Sappi is expanding its product range for corrugated board applications with Fusion Nature Plus.

With Fusion Nature Plus, Sappi is launching an uncoated, fully bleached and completely recyclable virgin fibre liner. The company provides a unique variety of packaging and speciality papers. The specialist in paper-based solutions also offers a wide range of products in relation to labels. Fusion Nature Plus offers excellent printing results in flexographic, digital and offset printing processes.

• Ultra-bright, uncoated virgin fibre paper with excellent printing results
• Ideal for attractive corrugated board as well as premium shopping bags
• Can be used as topliner, liner or fluting
• Available in grammages of 80 to 130 g/m²

The virgin fibre liner is based on the concept of the successful Fusion Topliner. In contrast to the double-coated Fusion Topliner, Fusion Nature Plus has a natural, uncoated surface with a more tactile feel, in response to the growing market appetite for this type of product. The liner is also provided in very low grammages.

Fusion Nature Plus enhances brand appearance

Brand owners, corrugated board processors, manufacturers of display cartons and folding cartons as well as designers all benefit from the versatility of the new Fusion Nature Plus. In contrast to conventional uncoated liner papers, the material offers high brightness, brilliant colour reproduction and consistently high quality. These features make the product the perfect choice for corrugated board or solid board packaging, where a very bright appearance is needed for topliners, inner liners and corrugating applications. Whether used as an inlay in cosmetics or confectionery packaging, or as a liner in shipping packaging to ensure an exceptional unboxing experience, Fusion Nature Plus is called upon wherever an enhanced appearance is desired.

Another area of application is paper carrier bags, where uncoated paper qualities are often preferred.

Fusion Nature Plus is ideally suited to a range of printing processes: the product achieves outstanding results in flexographic and offset printing. The pre-treated surface and high brightness offer clear advantages with regard to primer requirements and print behaviour, especially for inkjet-based digital printing. Bernd Gelder, Head of Sales Containerboard at Sappi Europe: ‘With its exceptional print quality and impressive colour reproduction, Fusion Nature Plus particularly appeals to packaging customers who value a natural look and feel in paper. The response from the market, in which packaging based on corrugated board still needs to take on a bigger role, is enormous, of course, with the result that we have succeeded in completing a number of interesting end applications and customer projects with Fusion Nature Plus shortly after market launch.’

Virgin fibre vital for recycling

In continuous recycling use, fiber that has already been recycled is subject to a progressive weakening of quality, resulting in a weakness in the products that incorporate them, but also, crucially, over time they will ultimately degrade to a point where they become unrecoverable. As a result, a certain amount of virgin fibre needs to be introduced into the cycle on a regular basis. Without continuous virgin fibre contribution to the pulp cycle, recycled producers will in the end run out of raw material. The premium virgin fibre liner Fusion Nature Plus from Sappi plays an important role here in maintaining the quality of the recycling substrate.

Thanks to the central location of Sappi’s production site in Ehingen, Fusion Nature Plus can be supplied quickly throughout Europe. The shorter transportation distances reduce transport related fossil emissions and protect the environment. The shorter production cycles in turn ensure high availability and rapid supply.

Fusion Nature Plus is currently available in six grammages from 80 to 130 g/m² in both sheet and roll form. Sappi can also provide Fusion Nature Plus with FSC or PEFC certificates on request.

“When it comes to working on new developments, we always start from new ideas and the constant research that starts from a concept that becomes reality, by increasingly raising the bar of sustainability” said Alice Tonello, R&D and Marketing Director of Tonello. “The research for technologies and solutions have always been part of our DNA, is a daily commitment to the environment, the market, our people and all human beings with their needs.  Based on this vision, two revolutionary patent-pending process, are born, Wake and OBleach, that allow to create incredible and totally responsible effects on garments” continued Alice Tonello.

This is how The Laundry (R)Evolution was born: a radically new conception thought to simplify and optimize the entire garment finishing process.

It involves only 2 technologies in the entire finishing cycle, reducing waste and optimizing resources: LaserBlaze, and The All-in-One-System. Metro is used, a software that processes real data, in real time to check all laundry consumption, optimizing processing times and improving performance.

The All-in-One System performs all washing operations by integrating 4 sustainable technologies into a single machine: ECOfree 2, which uses ozone in both the water and air; NoStone® for authentic and pumice-free stone-wash effects; UP, for washing processes with at least 50% less water; Core, a nebulizing system improving performance and reducing water consumption.

In terms of effects, the latest results of the Laundry (R)evolution are OBleach and Wake.

OBleach is the new Tonello patent-pending process which, by using only ozone, “returns to the future” with an authentic, sustainable and cool Bleach.

Wake is the first totally natural dyeing system. In fact, it uses only plants and vegetable waste, organic items like flowers, berries and roots left to dry and infuse, without harmful chemicals additives.

Tonello will be live during DenimsandJeans Virtual Show on October 14th and 15th.
