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%.

The testing service provider and research partner Hohenstein is joining the Innovation Park for Artificial Intelligence (IPAI) in Heilbronn. There are already points of contact with AI applications in some interdisciplinary research projects. In addition, there is the cooperation with the Munich-based start-up Sizekick and its AI-based technology for size recommendations, which aims to reduce size-related returns in online fashion retail.

"We expect the connection to the IPAI AI network to provide us with valuable impulses to remain fit for the future," explains Hohenstein CEO Dr. Timo Hammer, "This unique platform brings together a wide variety of players with their experience and knowledge. New ideas, projects and even products can be generated with great dynamism in the network as an intelligent response to future requirements. Because one thing is clear - artificial intelligence is THE key technology of the future".

The Innovation Park for Artificial Intelligence (IPAI) in Heilbronn (www.ip.ai) sees itself as an innovation platform for applied AI and a German lighthouse project with international appeal. The center is intended to map the entire AI value chain, from the qualification of specialists to the application of ethically responsible AI. The aim is to use the AI ecosystem to bring together companies, start-ups, research institutions, scientists, and public institutions and to secure Germany's digital independence and competitiveness in a key future technology.

More than 82 companies, businesses and social organizations – including AkzoNobel – are involved in a major Dutch research program focused on developing new technologies that will help solve some of today’s societal challenges.
 
Seven broad consortia have been established as part of the government-funded “Perspectief” program, with AkzoNobel set to play a leading role in the SusInkCoat project, which will explore how to make inks and coatings more sustainable.

The company will work together with private partners and other societal stakeholders to develop new materials, processes and applications to improve the durability, functionality and recyclability of coatings, thin films and inks. The program, which will run for the next five years, is backed by the Ministry of Economic Affairs and Climate Policy and the Dutch Research Council (NWO).

“Our discussions about collaborating with our SusInkCoat partners have been very positive,” says AkzoNobel’s R&D Director of Scientific Academic Programs, André van Linden, who is also the co-lead of SusInkCoat. “We’re all facing the same societal challenges – how to become more circular – and we’re looking for the same solutions in different application areas. But we’ve never done that together for this specific research topic, so we need an ecosystem to help us solve these challenges.
 
Van Linden adds that the program – one of many R&D projects the company is involved with – will also support AkzoNobel’s ambition to achieve 50% less carbon emissions in its own operations – and across the value chain – by 2030.
 
 “We want to make the recyclability of materials - such as furniture, building materials and steel constructions - easier by introducing functionalities like self-healing, higher durability and triggered release,” he continues. “The more you can leave the materials in their original state, the more sustainably you can operate.”

AkzoNobel will be collaborating with Canon, Evonik, GFB, PTG and RUG Ventures, who together possess extensive knowledge of market demands, supply chains and production processes. All the SusInkCoat partners will also work with academic researchers at several Dutch universities in an effort to identify promising developments that can be commercialized, used for education purposes or for outreach to the public.

Research being conducted by the other six consortia includes investigating methods to make tastier plant-based food; flat optics for more sustainable hi-tech equipment; and cheaper and more accessible medical imaging technology.

Fibre Extrusion Technology Limited (FET) has been awarded £50,000 of grant funding to collaborate with the University of Manchester on complex spin pack and spinneret designs. This funding will provide FET with access to the expertise of four universities and the National Physical Laboratory to develop the next generation of machinery.

The grant is awarded by a consortium led by AMPI (The Advanced Machinery and Productivity Institute) and NPL (The National Physical Laboratory). AMPI’s Innovation for Machinery (I4M) programme supports businesses in West Yorkshire and Greater Manchester as part of an overall initiative to drive innovation for the UK’s advanced machinery manufacturers to meet the challenges of developing new technology and entering emerging markets.

In this project, FET will be working with the University of Manchester to conduct computational fluid dynamics (CFD) studies on a number of complex spin pack and spinneret designs. The aim of this work is to identify areas of improvement for FET’s spin packs and spinnerets and to use computer aided designs to develop significantly more efficient versions. The goal is that the research will improve the throughput of FET extrusion systems, thus reducing the amount of polymer lost through inefficient flow paths. This development, in turn, will reduce the environmental impact of synthetic polymer processing.

FET designs, develops, and manufactures extrusion equipment for a range of high value textile material applications worldwide. Established in 1998, FET’s major strength has always been to collaborate with customers in testing, evaluating and developing high value materials with diverse, functional properties. Efficiency and sustainability are key, so enhanced development of spinneret technology will contribute significantly to these objectives.

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.
