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%.

INDA announces Sustainability as a primary focus for 2024. This strategic initiative, backed by resounding support from INDA’s leadership, is a direct response to feedback from association members affirming that sustainability remains one of the nonwovens industry’s highest priorities.

INDA’s sustainability endeavor will center around three core pillars crucial to the industry’s future: Responsible Sourcing, End-of-Life Solutions, and Innovations in Sustainability. This multifaceted initiative will introduce a spectrum of new and enhanced offerings, including:

• Webinars addressing sustainability issues impacting members and the industry.
• Specialized technical and government affairs committees enabling members to collaborate on sustainability opportunities and challenges.
• The inaugural release of a comprehensive sustainability report from INDA’s Market Intelligence department.
• A dedicated sustainability special edition of the International Fiber Journal, produced by INDA Media.
• Sustainability programming at INDA events, including a dedicated focus at the IDEA® 2025 conference.

“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.

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.
