Recycled fibres: Swiss manufacturers for circularity

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.

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%.

In China, the textile industry is forward-looking and resilient – with a healthy appetite for new technologies and a determination to keep its leading position. Sustainability is increasingly coming into focus, so there is a growing demand for recycling technologies, as well as automated solutions and digitalization. Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association, is clear: “China is the main market for a large number of our association members.” On top of growing consumer demand and technological capabilities, the latest ambitious five-year plan will drive further development of the Chinese textile industry in world markets, and Swiss companies will work with all stakeholders to enable its success.

Market proximity
Swiss companies realized many years ago that geographical proximity is the key to success. Stäubli has started to set up offices in Chinese cities since 1998 and counts 12 locations today, to serve the whole country. In 2002, Itema established a centralized local branch which today has 160 employees in various functions. Loepfe has expanded its presence by creating an independent local business unit to overcome the 9,000 km distance by air, while Uster Technologies has had a Chinese subsidiary since 1982, with offices and service stations in different provinces. Luwa set up its offices and workshop in Shanghai in 1997. Rieter established a presence in mainland China in 2005, driven by a strong commitment to expanding the country’s know-how and expertise – and ten years later opened an advanced research center. All Swiss companies with serious business goals in China have made similar commitments to connect with customers and maintain strong relationships.

Understanding Chinese customers
Swiss companies also understand that Chinese customers require dedicated attention, and that speed is more essential than ever in delivering both machines and services.
Manufacturers in China are seeking cost-effective solutions to remain competitive, while consumers are looking for value in their purchases. Companies need to develop solutions that provide tangible economic benefits to their clients. Furthermore, energy savings have become paramount in China, due to the government's commitment to environmental sustainability and reduced carbon emissions. “Businesses are adopting more energy-efficient processes and technologies to meet stringent energy conservation and emission reduction targets,” says Peter Schnickmann, Managing Director at Luwa Air Engineering (Shanghai). He notes an investment trend for solutions helping Chinese companies cut operational costs and minimize their carbon footprint.

To enhance the reputation of both companies and products – and boost the image of the entire industry – the environmental impact needs to decrease. Priorities are saving water and waste, as well as reducing, replacing or completely eliminating the use of harmful substances. China has a strong demand for environmental-friendly solutions and sustainable technologies.

Customer-oriented in weaving
The huge number of Chinese fabric producers calls for an immense volume of weaving machinery to be supplied by international and local providers. Swiss machinery manufacturers hold an impressive share of this business.
Chinese weavers require advanced technology, with increasingly higher standards of efficiency. In weaving preparation, latest solutions match the speed, quality and reliability now wanted. Weaving machines too offer the eco-efficiency, performance, and ease of use needed, with innovations that extend the scope of sustainable weaving, and open-platform systems configurable to weavers’ specific operations. A huge increase in demand for technical textiles in recent years has been driven by applications such as carbon fiber, aramid and glass fiber.

Profitable in spinning
China’s competitive advantages come from its large-scale and integrated manufacturing capabilities, along with the use of advanced automation and digitization technologies. Spinners aim to capitalize on extended market opportunities, with more economical production. The latest air-jet spinning machines serve these goals, allowing exceptionally low production costs per kilogram of yarn, coupled with high flexibility and reliability. Sustainable yarns are in great demand.

The automation trend in spinning mills focuses on connecting production processes. Data is used to ensure the highest quality standards, most efficient raw material usage, reduction of waste, and energy savings. To make spinning mills more competitive, latest solutions combine cutting-edge hardware, data-enabled software and renowned textile expertise.

Swiss Textile Machinery Association: Symposium in Indonesia

  • Free trade deal boosts export potential

The time is right for Swiss textile machinery companies to grow their export business with Indonesia – one of the world’s top 10 textile producers. A free trade agreement between the two countries came into force in 2021, and market analyses show that there is scope for a significant increase in business in textile and textile machinery sectors.

This was the background to a successful symposium in the Indonesian capital Jakarta last month when Swiss Textile Machinery Association members presented their products and innovations to an invited audience of 200 delegates from Indonesian textile companies.

The symposium audience was welcomed by Philippe Strub, of the Swiss Embassy in Indonesia; Ignatius Warsito, from the Indonesia Ministry of Industry’s Chemical, Pharmaceutical and Textile Industry branch; Anne Patricia Sutanto, of the Indonesian Textile Association (API); and Ernesto Maurer, President of the Swiss Textile Machinery Association.

Swiss companies taking part were: Stäubli, Zeta Datatec, Loepfe, Saurer, Benninger, Rieter, Bräcker, Jakob Müller, Maag, Uster and SERV.

Swiss companies taking part were: Stäubli, Zeta Datatec, Loepfe, Saurer, Benninger, Rieter, Bräcker, Jakob Müller, Maag, Uster and SERV.

The presentations were followed by panel discussions with speakers, and there were also networking opportunities at the companies’ exhibition tables.

Also taking part in a panel at the event was Testex, the independent Swiss organisation which provides testing, certification, OEKO-TEX® and other labels for the textile industry. Discussion focused on the relevance of innovation in textile technology to sustainability and ‘saving the planet.’  

Recent years have seen an acceleration in trade relations between Switzerland and Indonesia, which in 2008 was classed as one of eight priority countries for economic development cooperation by SECO, the Swiss Secretariat for Economic Affairs, with a joint economic and trade commission established the following year.
Collaboration was heightened further in 2018 with a Comprehensive Economic Partnership Agreement (CEPA) for Indonesia with Switzerland and the other EFTA countries. This more extensive form of free trade agreement was accepted after a popular referendum, and ultimately came into force in November 2021.

Trading between the two countries is supported by SERV, the Swiss export risk insurance organisation. This insures export goods against political and commercial risks and facilitates credit.

Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association, said the Indonesia Symposium was ideally-timed, right after the CEPA came into effect: “With the free trade agreement in place, there is even greater potential for the development of trade between our countries,” she said.

“Business in textile and textile machinery is actually below the relative market shares for the sectors, so this stronger cooperation is probably overdue. It was a successful symposium, with enthusiastic participation from Indonesian textile companies, so we are optimistic about future export prospects for Swiss textile machinery.”

Swiss Textile Machinery technology and innovations for technical textiles

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

Swiss textile machinery going digital: Innovative technology for new business models

Digitalization is a big story in the world of business. It’s all about change, making use of technology to transform attitudes and create new opportunities to grow revenue. At its heart is innovation, with new systems and intelligent use of data. In textiles, the entire value chain is going digital, as evidenced by the commitment of Swiss Textile Machinery Association member firms. Their story – presented here in six ‘chapters’ – spans industry sectors through spinning, weaving, finishing and nonwovens.

Digitalization is a big story in the world of business. It’s all about change, making use of technology to transform attitudes and create new opportunities to grow revenue. At its heart is innovation, with new systems and intelligent use of data. In textiles, the entire value chain is going digital, as evidenced by the commitment of Swiss Textile Machinery Association member firms. Their story – presented here in six ‘chapters’ – spans industry sectors through spinning, weaving, finishing and nonwovens.

Cost savings and more
The process of digitalization in the textile industry today is continuous – faster in some segments than others – but noticeable everywhere. Automation is promising in many areas of finishing and making-up, where initial investments are being made. An example is folding of finished goods, previously a slow manual operation. Now, high-performance automatic folding machines from Swiss company Espritech deliver the potential for cost savings, unlocking new options for positive change at this most labor-intensive stage of production. For manufacturers in low-cost areas, the benefit results from its volume and is a simple financial one. In higher-cost segments, the application of this technology can be part of a completely new business model, taking production closer to the end customer.

Better process, better workplace
Pioneering in the field of digitalization embraces social responsibility along with the introduction of bold new technological innovation. That’s a commitment made by Uster, as it aims to shape future working practices in the textile industry in areas where its systems are applied. In fabric inspection, that means combining the strengths of human capabilities with the performance of Artificial Intelligence. Automatic defect classification with machine learning technology is the next leap in digitalization for fabric manufacturers, following on from automated detection of fabric faults, which is already well established in weaving and finishing mills. This will bring benefits in profitability for the manufacturer – as well as an improved working environment for their operatives, freed from repetitive tasks.

Information, flexible and fast
Access to data is critical in the digitalized world of textiles. It must be flexible, fast and secure, and available to all levels of the company – worldwide. Jakob Muller serves the narrow fabrics industry ideally with a digitalization portal, perfectly developed to provide essential production information. The portal is a browser-based production data acquisition system, with direct access to the machine controls. The system offers unique data monitoring and communication on a global framework. Digitized weave rooms present information 24/7 on desktops at the customer’s plant, as well as on tablets and smartphones remotely.

Making the most of it
Rieter takes advantage of latest digital technology to offer customers a unique experience. Their digital spinning suite helps spinners overcome their daily challenges and manage costs and efficiency more effectively. This all-in-one mill management system connects all the machinery, giving quick access to the right information and a holistic view, from bale to yarn. Users profit from full transparency, and are presented with recommendations based on long-standing experience and know-how. This is digitalization at its most practical, applied to allow spinners to make the most of their installed machinery.

Production, service, training – digital everything
As a solutions provider, Saurer puts digitalization at the core of business, integral to its technology offering to customers. Some latest examples include self-optimization of spinning machines, and a fully automated transport of cylindrical or conical cross-wound packages. These are automatically stored in an internal buffer system, for later feeding to subsequent processes. Of course after-sales service is also digital: the e-shop and machine information hub, together with the web-based training centre, ensure that knowledge is transferred to customers – turning employees into experts.

See the future system today
Autefa Solutions uses the concept of digital twinning, visualizing any real-world concept of a nonwovens line to make it easier for potential customers to grasp the idea. It’s also a big help for training and servicing needs. Most of all they digitalize important parts e.g. of a baling press line with perfectly interconnecting software tools. This is an excellent method for reducing commissioning times. Ordered bale presses reach technical readiness in the form of a digital twin, before they are commissioned in the real world. This typically halves the total time to get the line up and running.
Speaking on behalf of Swiss Textile Machinery Association members, André Imhof, CEO of Autefa Solutions Switzerland AG, says: “Making digitalization our friend opens doors for business model innovations, which is essential for our industry competitiveness. The approach is to digitalize everything that can be digitalized. We won’t stop.”
