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.

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.

• ESD protection in harsh environments:
• Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
• Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
• Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.

Nach dem German Innovation Award und dem German Design Award hat drapilux den German Brand Award in der Kategorie „Interior und Living“ für seine exzellente Markenstrategie erhalten.

Auf dem Markt ist drapilux nicht nur der Hersteller von Bezugs- und Dekorationsstoffen mit der größten Auswahl an intelligenten Funktionen, sondern hat diese überhaupt erst eingeführt. Sicherheit, Hygiene, Raumqualität und Akustik werden durch die Funktionen „flammstop“, „akustik“, „air“ und „bioaktiv“ der drapilux-Textilien erheblich verbessert.

Das spiegelt sich deutlich in der Corporate Identity wider: „drapilux hat mit seiner ‚Mehr als nur Stoff‘-Imagekampagne den Markenkern besser denn je auf den Punkt gebracht“, sagt Marketingleiter Markus Overbeck, der den German Brand Award in Berlin entgegennahm. So bezeichnet der Claim „Intelligence woven in“, zu Deutsch „gewebte Intelligenz“, die hohe Qualität der Textilien mit eingebauter Sicherheit, für die die Marke international bekannt ist.
       
Dass die Textilien „innere Werte“ besitzen und damit Kunden im Alltag einen echten Mehrwert bieten, wird anhand symbolhaft dargestellten Stoffnachbildungen sichtbar: Ein roter Stoff-Feuerlöscher, grüne Ohrenschützer aus Textil, ein blauer, gewebter Ventilator und eine rosafarbene Textil-Desinfektionsmittelflasche zeigen auf der Webseite, auf Messen, auf allen Kommunikationskanälen, wofür drapilux steht. Die vier Imagemotive sind zu den Sinnbildern für die Alleinstellungsmerkmale von drapilux geworden. „Die Strategie, für die die Marke ausgezeichnet wurde, bauen wir auch weiter aus. Dazu wird es eine weiterführende Kampagne geben, die noch im Laufe des Jahres starten wird“, so Overbeck.
