From the Sector

Kelheim Fibres, a manufacturer of specialty viscose fibres, showcases its latest developments at this year's Global Fiber Congress in Dornbirn. The focus is on innovative solutions that not only promote environmental sustainability but also strengthen the European supply chain.

In his presentation "Towards high performing plant-based AHP products - a joined approach of Pelz and Kelheim Fibres," Dr. Ingo Bernt, Project Leader of Fiber & Application Development at Kelheim Fibres, together with Dr. Henning Röttger, Head of Business Development at PelzGROUP, introduces the development of a plastic-free yet high-performance panty liner. The water-repellent Kelheim specialty fibre Olea plays a crucial role in both the top and backsheet of the panty liner. This product emerged from the ambition to offer eco-friendly alternatives to conventional disposable hygiene solutions without compromising on product performance.

A similar approach is pursued in the second presented project. Under the title "Performance Fibres meet Sustainable Design - example of a reusable Baby Diaper," Natalie Wunder, Project Leader from Kelheim Fibres' New Business Development team, together with Caspar Böhme, Co-Founder of Sumo, introduce the washable and reusable SUMO diaper. Made from biobased materials and featuring a unique construction with Kelheim specialty fibres, this combination offers double environmental benefits compared to conventional disposable baby diapers.

Both the panty liner and the SUMO diaper are manufactured entirely in Europe, resulting in shorter transportation routes and a reduced CO2 footprint. Moreover, these innovations contribute to strengthening the European textile and nonwovens industries by fostering innovation within Europe.

The viscose specialty fibre manufacturer Kelheim Fibres has entered into a collaboration with MagnoLab, an international network of companies in the textile industry based in the Biella region, Italy.

This partnership highlights the importance of collaboration between different companies to drive innovation and sustainability in the textile industry. Kelheim Fibres sees itself not only as a fibre supplier but also as an innovation partner for the entire industry. Through its Open Innovation approach, Kelheim Fibres fosters the exchange of ideas and knowledge to jointly develop sustainable solutions for the future.

Kelheim Fibres operates several pilot and technical facilities itself. The close collaboration with MagnoLab, which boasts an impressive array of state-of-the-art textile machinery, allows for even more efficient research and development.

The cooperation allows for practical testing, accelerating the implementation of innovations. It also contributes to a closer networking of the European (and thus regional) value chain. Thanks to shorter transport routes within Europe, not only is the environmental impact reduced, but also the realization of innovations in Europe is facilitated.

Dr. Marina Crnoja-Cosic, Director New Business Development, Marketing & Communications at Kelheim Fibres, emphasizes the advantages of the collaboration: " Through close networking with the companies organized under MagnoLab, we can produce small quantities of samples and prototypes using various technologies. This enables us to develop solutions based on our specialty fibres that can be directly transferred to our partners' production facilities within the textile value chain."

RadiciGroup took part in the Phygital Sustainability Expo, this year in its fourth edition, which was held in Rome on 5 and 6 July. This event is entirely dedicated to the ecological transition of fashion and design brands through technological innovation. The show is an important platform for discussion on sustainable transition issues, involving Italian and international brands, fashion tech start-ups, representatives from the institutional, business and educational fields, and consumers.

RadiciGroup's participation in the event was further evidence of the Group's commitment to making a contribution to sustainability and circularity in the fashion and textile industry, in collaboration with all the other players in the supply chain. During the narrated fashion show, held on the evening of Wednesday, 5 July, in the evocative archaeological complex of the Imperial Forum Museum, RadiciGroup presented a maxi dress made of Biofeel® eleven, a yarn of completely natural origin featuring high technical, aesthetic and environmental performance. This yarn is produced starting from a small bean cultivated in India on semi-arid land and thus does not compete with human food production. These beans yield a special oil ideal for obtaining biopolymers, such as the one produced by Arkema and spun into yarn at RadiciGroup in Italy.

The dress is not only made from a low environmental impact raw material, but is also an example of ecodesign: the garment was realized on a Shima Seiki WholeGarment knitting machine, where the entire item was knit directly from spools of Biofeel® eleven yarn, bypassing the traditional stages of weaving and tailoring. It is a zero-waste process, as only the quantity of yarn strictly needed for the garment is used.

Biofeel® eleven yarn endows the dress with unique characteristics, including low moisture absorption, greater lightness and high resistance and durability. Besides being 100% biobased, the yarn is also 100% recyclable because it is made of a mono-material polymer, which facilitates its end-of-life recycling and processing into new materials suitable for any application requiring high performance.

Trevira CS is exhibiting for the first time at CSI Miami (Cruise Ship Interiors Design Expo Americas). Taking place on 6 – 7 June, 2023 at the Miami Beach Convention Center, CSI will bring together buyers and suppliers involved in cruise ship interiors, including interior designers, architects, outfitters, shipyards and suppliers.
 
On the Trevira CS stand, visitors can get an idea of the wide range of flame retardant fabrics suitable for use on board cruise ships. 53 fabrics from 20 Trevira CS customers will be on display that either have IMO certification and/or have been tested to the fire safety standards (FTP Code) required in the marine sector. Trevira CS fabrics are inherently flame retardant, meaning that their flame retardant properties cannot be washed out or lost through aging or use. This is due to the chemical structure of the polyester fiber: the flame retardant properties are firmly anchored in the fiber and cannot be altered by external influences. A surface-applied flame retardant finish is therefore not necessary.

In the marine sector, the demands placed on textiles are not only high in terms of fire protection, but also with regards to light resistance and durability. This is particularly true for textiles used in outdoor applications. These must be extremely robust, as they are exposed to moisture and sunlight. To meet these requirements, Trevira CS has launched a range of 30 new spun-dyed, UV-stable filament yarns. Besides color depth and durability, spun-dyed yarns offer another advantage: They are more sustainable because the fabrics made from them can be produced in a more environmentally friendly way than textiles that are dyed in one piece or consist of brightly colored yarns. In fabric production, a large share of resource consumption goes to the dyeing and finishing of fabrics as well as the use of chemicals and water. However, with spun-dyed yarns, these processing steps are unnecessary – the yarn immediately comes out of the spinneret in the desired color, reducing the products’ environmental impact.

The topic of sustainability is also taken up in other Trevira CS products. For example, Trevira CS fabrics are available in recycled versions. They consist of fiber and filament yarns obtained in different recycling processes. Filament yarns are produced using recycled PET bottles, they contain 50% post-consumer recycled material. Recycled fibers are obtained using an agglomeration plant and in further processing steps from residual pre-consumer waste from production. They consist of 100% recycled material (pre-consumer recycling). All flame retardant recycled Trevira® products are GRS (Global Recycled Standard) certified.
Fabrics made from these yarns are marked with the Trevira CS eco trademark. The prerequisite for this is a recycled content of at least 50%. Among the fabrics presented at the Trevira CS trade fair stand are 8 fabrics bearing the Trevira CS eco brand.

The long-term goal in developing sustainable products is undoubtedly to enter a circular economy. For this new path, an innovative Trevira CS product development was launched, producing flame retardant fibers and filament yarns from chemically recycled raw material. In this case, the basic raw material for the chemical recycling was PET bottles, but essentially it could be most any other PET recyclables, such as packaging material or even textiles. Chemical recycling involves depolymerization, a sequence of chemical reactions in which the polymer chains are broken down again into their original components, i. e. the monomers. In a further processing step, impurities are removed. Before the polymerization process is initiated, a small amount of MEG (mono ethylene glycol) is added.

The same technology used to produce the original (virgin) raw material for Trevira CS is also used here. The flame retardant modification is added during polymerization. In this way, the flame retardant properties are indelibly anchored in the polymer.

By recycling valuable materials such as packaging material, waste can be avoided. The raw material obtained from the recycling process is comparable to the original material can be used again in high-quality products.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK has strengthened its technical team with the appointment of Dr Jonny Hunter as Research & Development Manager. Hunter brings a wealth of academic credentials to the department, including a Master’s in Medicinal and Biological Chemistry and a PhD in Sustainable Chemistry.

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

• Less C0₂ emissions + sustainable + recyclable

Sustainability first - this is the principle of the Institut für Textiltechnik (ITA) of RWTH Aachen University at JEC World 2023. ITA combines various lightweight construction technologies to reduce C0₂ and to use renewable and/or recyclable raw materials.

ITA presents innovations in the production of reinforcing fibres and in the textile processing of high-modulus fibres. It also shows the impregnation of high-modulus fibres with thermosetting and thermoplastic matrix systems.  

ITA will be exhibiting in hall 6 together with Textechno, Mönchengladbach, Germany, textile testing equipment and Maruhachi Fukui, Japan, Thermoplastic Composite Material Systems. The Interreg AACOMA project will also be presented at the stand. 

RadiciGroup presented Biofeel® Eleven, a yarn of natural origin, at the Performance Days trade fair (from March 15-16 in Munich). Biofeel® Eleven is sourced from castor oil and is suitable for obtaining bio-polymer. It can be used for fabrics and fine garments in many sectors, from fashion to sports, from automotive to home textiles.

Today, 80% of the world's castor-oil plantations are in India, particularly in the Gujarat region, due to its favourable climatic conditions. In this area, local people can earn an additional income by cultivating semi-arid land that does not compete with food production, and by applying the skills they have acquired over time to this work. Over the years, thanks to research, development and innovation in the value chain, the seeds from which the oil is produced have been selected and certified to ensure the finest quality, also in terms of end uses.

Castor beans contain around 45% oil, rich in ricinolein, from which the bio-polymer polyamide 11 is derived. This is the polymer RadiciGroup uses for its Biofeel® Eleven yarn. What remains after the first pressing is a highly effective bio-fertiliser that is returned to the soil.

Biofeel® Eleven can also be solution dyed, i.e. dyed at the yarn production stage, saving a great deal of water and energy and also providing greater colour stability.
