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%.

A major capacity expansion has been completed at AkzoNobel’s Powder Coatings site in Como, Italy, which will help secure supply to customers across Europe, Middle East and Africa (EMEA).

Four new manufacturing lines are now operational following the €21 million project – two of them dedicated to automotive primers and two to architectural coatings. New bonding equipment lines have also been added, ensuring that the products meet and exceed industry standards.

The extra capacity in Como has been installed in a renovated building where powder coatings were originally made – a sustainable reuse of an existing part of the site, which was established in 1992. The new lines also use recycled energy and are focused on meeting the highest standards in sustainable production, supporting the company’s ambition to reduce its carbon emissions by 50% by 2030.

AkzoNobel’s Como site is the company’s largest plant for producing powder coatings. It supplies products for market segments, such as home appliances, architecture, automotive, furniture and more.

The Aachen-based start-up SA-Dynamics is developing sustainable, bio-based and biodegradable insulation materials made from aerogel fibres, thereby setting new standards in resource-saving construction. Dr Sascha Schriever (Institut für Textiltechnik ITA), Maximilian Mohr (ITA), Dr Jens Hofer (ITA Postdoc) and Dr Christian Schwotzer (Department for Industrial Furnaces and Heat Engineering IOB), who trained at RWTH Aachen University, were awarded first place in the KUER.NRW Business Plan Competition 2023 and prize money of €6,000.

SA-Dynamics relies on the impressive properties of aerogel fibres: they have excellent insulating properties, are lightweight, durable, robust, versatile and can be processed very well on conventional textile machines thanks to their flexibility. This makes them comparable to polystyrene, but still sustainable, as SA Dynamics uses bio-based and biodegradable raw materials.

"We can revolutionise the construction world with bio-based aerogel fibres," explains ITA founder Dr Sascha Schriever proudly. "If all insulation materials in construction are converted to bio-based aerogel fibres, all builders can realise their dream of a sustainable house."

SA Dynamics has come a good deal closer to its founding goal by winning the KUER.NRW 2023 business plan competition. The spin-off from Institut für Textiltechnik (ITA) and Department for Industrial Furnaces and Heat Engineering (IOB) at RWTH Aachen University is scheduled for spring 2025.

A lot of waste is generated in the trade fair and event industry. It makes sense to have furniture that can quickly be dismantled and stored to save space - or simply disposed of and recycled. Paper is the ideal raw material here: locally available and renewable. It also has an established recycling process. The German Institutes of Textile and Fiber Research (DITF) and their project partners have jointly developed a recycling-friendly modular system for trade fair furniture. The "PapierEvents" project was funded by the German Federal Environmental Foundation (DBU).

Once the paper has been brought into yarn form, it can be processed into a wide variety of basic elements using the structure winding process, creating a completely new design language.

The unusual look is created in the structure winding process. In this technology developed at the DITF, the yarn is deposited precisely on a rotating mandrel. This enables high process speeds and a high degree of automation. After the winding process, the individual yarns are fixed, creating a self-supporting component. A starch-based adhesive, which is also made from renewable and degradable raw materials, was used in the project for the fixation.

The recyclability of all the basic elements developed in the project was investigated and confirmed. For this purpose the research colleagues at the project partner from the Department of Paper Production and Mechanical Process Engineering at TU Darmstadt (PMV) used the CEPI method, a new standard test procedure from the Confederation of European Paper Industries.

Sensor and lighting functions were also implemented in a recycling-friendly manner. The paper sensor yarns are integrated into the components and detect contact.

Also, a modular system for trade fair and event furniture was developed. The furniture is lightweight and modular. For example, the total weight of the counter shown is well under ten kilograms and individual parts can easily be shipped in standard packages. All parts can be used several times, making them suitable for campaigns lasting several weeks.

A counter, a customer stopper in DIN A1 format and a pyramid-shaped stand were used as demonstrators. The research work of the DITF (textile technology) and PMV (paper processing) was supplemented by other partners: GarnTec GmbH developed the paper yarns used, the industrial designers from quintessence design provided important suggestions for the visual and functional design of the elements and connectors and the event agency Rödig GmbH evaluated the ideas and concepts in terms of usability in practical use.

• Dibella increases the use of Cotton made in Africa cotton according to the mass balance system from 300,000kg in 2023 to 750,000kg in 2024.

With Cotton made in Africa (CmiA), Dibella is making its business model even more sustainable. This enables the company to minimise its environmental impact and support the people in the growing regions. Dibella relies on the CmiA mass balance system in the chain to achieve its corporate goal of "increasing the use of sustainable fibres".

Cotton made in Africa initiative is an internationally recognised standard for sustainable cotton grown by African smallholder farmers. With up to 13% less greenhouse gas emissions, CmiA-verified cotton has a significantly lower impact on the environment than the global average and also supports village communities in Africa beyond sustainable cotton cultivation. CmiA supports smallholder farmers in sub-Saharan Africa in the sustainable cultivation of genetically unmodified cotton and is committed to improving working conditions in ginning factories. Through a licence fee, which is paid by customers like Dibella, the farmers receive training and access to operating resources in order to reduce the use of pesticides and increase the quality of their cotton and yields from their fields at the same time.

Cotton made in Africa takes a pragmatic approach to the processing of its cotton with two different models in order to best meet the demands for transparency and feasibility in the chain: The Hard Identity Preserved System and the Mass Balance System; Dibella has opted for the latter. While CmiA-verified cotton is always traded separately from other cotton right up to the spinning mill and can therefore be traced seamlessly from the growing region to the ginning plant to the spinning mill, the mass balance system allows CmiA cotton to be mixed with cotton of other origins at the spinning mill level as long as a balance between cotton purchases and CmiA-labelled yarns is ensured. This principle ensures the purchase of sustainably grown fibres and helps Dibella to bring a larger quantity of sustainable cotton into its textile cycle, which ultimately benefits smallholder farmers.
