From the Sector

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

“From Earth to Earth”: The new plan defines goals and concrete actions in Environmental, Social and Governance (ESG) areas to foster value creation for all stakeholders and put new sustainability regulatory requirements at the centre of attention.

A project, designed to enhance RadiciGroup's transparency and commitment to develop a responsible business along its entire value chain from an economic, social and environmental perspective and focus on the ever more widespread and stringent sustainability regulatory requirements. These are the features and goals of the Sustainability Plan presented by the Group and called "From Earth to Earth", precisely to emphasize the intent to focus on the Earth and future generations.

In the context of a complex and constantly changing scenario, the Group has therefore decided to capitalize on the goals achieved and look beyond them with a plan defining the medium-term targets and the actions to be taken to fulfil them and covering all areas considered to be "material”, i.e., relevant from the point of view of ESG and financial risks, opportunities and impacts. Indeed, the ultimate goal of "From Earth to Earth" is to support business continuity and the growth of the company and all its stakeholders.

The project was the result of a multi-year collaboration with Deloitte, which contributed an external and objective viewpoint on the definition of the material targets and themes. However, it was not an armchair exercise, but the result of an extensive listening process involving internal and external stakeholders, all of whom were sustainability experts who helped define a shortlist of strategic themes for both the Group and its main stakeholders. These issues were then analysed in detail using working tables on the different themes to identify the objectives in Environmental, Social and Governance areas and the related concrete actions needed to achieve them, in line with the European decarbonization and energy transition policies and the
United Nations Sustainable Development Goals, a global blueprint for sustainable growth.

In particular, RadiciGroup’s environmental goals include: a 20% increase and differentiation in renewable source electricity consumption, an 80% reduction in total direct greenhouse gas emissions by 2030 compared to 2011, attention to water consumption to limit the impact on local communities and biodiversity, the extension of Life Cycle Assessment (LCA) methodology to measure the environmental impact of 70% of the products (in terms of weight) manufactured by the entire Group, collaboration among the various actors in the supply chain from an ecodesign perspective and the search for increasingly more sustainable and circular packaging solutions.

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.

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.

Panda Biotech announced that building construction is complete and the official commissioning process to bring its Panda High Plains Hemp Gin™ (the “Panda Hemp Gin”) project online began in early Q4. The commissioning process marks the final stage before beginning commercial operations in Q1 2024 at the 500,000 square foot Wichita Falls, Texas facility. The Panda Hemp Gin will process 10 metric tons of industrial hemp per hour to produce textile-grade fiber, hurd, short-fiber hurd mix, and a nutrient-rich co-product that will be pelletized. The facility is expected to be the largest hemp decortication center in the Western Hemisphere and among the largest in the world.

Using only renewable energy sources, the engineering and production process at the Panda Hemp Gin has been certified green by Mid-South Engineering Company, in accordance with the International Capital Market Association’s Green Bond Principles. Panda Biotech has also partnered with Oritain, a scientific traceability company, to bring the most traceable hemp grown 100 percent in the United States to market.

Additionally, Panda Biotech is actively signing contracts with producers to grow the hemp feedstock for the 2024 growing season, as well as purchasing hemp fiber that has already been harvested or processed. The company recently unveiled an unmatched pay-to-grow program for producers to begin growing Panda hemp. With up-front, guaranteed money and agronomy support, Panda producers also receive tested and proven seed at no cost, successfully mitigating the risk producers may assume and underscoring Panda’s commitment and promise to the farming community. The benefits of growing hemp are substantial, as it is an excellent rotational crop that remediates the soil and provides a competitive margin.

“Each piece of the Panda Hemp Gin production line, including the three miles of overhead pneumatic duct lines, refining, blending, mechanical cottonization, hurd bagging and storage, baling, and more, must be individually started, checked, balanced, and commissioned,” says Panda Biotech Executive Vice President Scott Evans. “Currently, all equipment is individually being brought online to be officially placed in service.”

Faster and more cost-effective carbon fibre production - the technology of the start-up CarboScreen comes a good deal closer to this dream. The founders Dr. Musa Akdere, Felix Pohlkemper and Tim Röding from the Institut für Textiltechnik (ITA) of RWTH Aachen University are using sensor technology to monitor carbon fibre production, thereby doubling the production speed from the current 15 to 30 m/min in the medium term and increasing turnover by up to €37.5 million per year and system. This ground-breaking development also impressed the jury at the ITMF at their Annual Conference in Keqiao, China, and was honoured with the ITMF StartUp Award 2023 on 6 November 2023.

Dr. Musa Akdere accepted the award on behalf of the CarboScreen founding team.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Both types of damage cannot be optimally detected by current means or only become apparent after production, to name just two examples. This leads to higher production costs. In an emergency, faulty production can even lead to plant fires. For this reason, and to ensure good production quality, the system is run at 15 m/min below its production capacity for safety reasons. However, 30 m/min or more would be possible. With the sensor-based online monitoring of CarboScreen, the production capacity can be doubled to 30 /min. This would lead to higher production, resulting in lower manufacturing costs and wider use of carbon fibres in mass markets such as automotive, aerospace and wind energy.

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The production of carbon fibres is highly complex. In the current state of the art, however, the manufacturing process is only monitored manually by semi-skilled workers. However, even minimal fibre damage during production leads to a reduction in the quality of the carbon fibre. In extreme cases, it can also lead to plant fires. To ensure production quality, the production speed is currently limited to a maximum of 15 m/min. In fact, the production speed of the systems could be higher. The sensor-based online monitoring of Carbo-Screen makes it possible to increase the production speed to 30 m/min in the medium term. As a result of the increased production volume per system, the specific production costs of the carbon fibre are reduced, which can result in lower prices.

A reduced sales price would make it possible to use carbon fibres and their composite materials even more widely in traditional markets such as aerospace technology and wind energy, as well as for mass production in the automotive industry.

The CarboScreen online monitoring system is currently being developed for industrial use. It is to be validated at an industrial plant in 2024. CarboScreen GmbH was founded as part of EXIST funding and offers AI-supported sensor systems for carbon fibre production. The sensor technology continuously monitors the fibre throughout the entire production process. Deviations are detected automatically.

The winners of the AVK Innovation Award are honoured annually by the AVK Industrievereinigung Verstärkte Kunststoffe. Companies, institutes and their partners are honoured in three categories: products and applications, processes and procedures, and research and science.

Tampon for Men by Finnish hygiene product brand Vuokkoset aims to alleviate the distress transgender men feel related to menstruation. The creative partner behind the idea is TBWA\Helsinki. The product was launched during the international Transgender Awareness Week and sparked a discussion in Scandinavia of the inclusivity of the health and wellness industry.

Research has shown that 93% of transgender men have experienced gender dysphoria related to menstruation. With a tampon designed for men, Vuokkoset sparked a vivid conversation in Finland during the International transgender awareness week (Nov 13 to 19, 2023) with an aim to change perceptions of menstruation and reduce the distress it causes to transgender men.

“Marketing has a huge role in shaping the world around us. As Finland’s leading creative agency and the leading global agency collective, we have an immense responsibility in actively making the world more inclusive. Vuokkoset is a brand that shares this value base and was brave enough to put the campaign together with us in just four short weeks” says Heidi Taina, creative director from TBWA\Helsinki.

Trans men and non-binary individuals may still have menstrual cycles, regardless of hormone therapy choices. This highlights the diversity in experiences related to menstruation among different gender identities.

"When I was young, menstruation felt not only strange but somehow wrong. Our culture does not really acknowledge the diversity of menstruating individuals" says DEI consultant and face of the campaign Dakota Robin, who has been through the gender affirming process himself.

The Tampon for Men will be available as a limited edition in Finland and wider distribution will begin in early 2024. Total sales proceeds are donated to Trasek ry, an organization focused on gender diversity and sexual health. A fully gender-neutral tampon product by Vuokkoset is also being considered.

"Menstrual products - from visuality, advertising to store location - are strongly feminine. It’s time to acknowledge the diversity of menstruating individuals" says Sanna Karhu, CEO of Delipap Oy, the company that manufactures Vuokkoset products.

"This is definitely a step in the right direction. By changing attitudes and broadening perspectives, we can also remove discrimination against gender minorities," concludes Dakota Robin.
