From the Sector

The Karl Mayer Group is reducing its ecological footprint when it comes to energy utilisation: The Group's largest photovoltaic system to date has just been installed at its headquarters in Obertshausen.

Following the construction of a stable substructure, the first photovoltaic elements were installed on the roof of the assembly hall in Obertshausen on 16 February 2024. This will be followed by the step-by-step conversion of other roofs. If everything goes according to plan, around 6,000 modules will have been installed on an area of approx. 12,000 m² and over 60,000 metres of cable laid by the middle of the year.

"With a total output of 2.4 MWp, we will be able to generate over 35% of the total electricity consumption at the site ourselves," explains Michael Sustelo, Head of Facility Management at the Karl Mayer Group.

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%.

Monforts' new Montex 8500 stenter line was recently installed at Curt Bauer’s plant in Aue in Germany.

Curt Bauer has been in continuous operation for 150 years, beginning as a weaving mill in Aue in the Ore Mountains region of Saxony back in 1882. Today, with 120 employees, the company has an annual production of 2.2 million metres of fabric and specialises in three key fields – home textiles, special damask fabrics for West African garments and technical textiles.

A first Montex stenter was installed by Monforts at the Aue plant in 2003 and an older machine from a third party supplier was also still in operation prior to the latest upgrade.
“The replacement of our older existing stenter, which was installed in 1985, was long overdue,” explains Gert Bauer. “It had a maximum working width of 2.2 metres and we were looking to both increase productivity and reduce energy requirements.”

As a consequence, the company opted for a new Montex 8500 line with a working width of 3.2 metres equipped with the MonforClean heat recovery and exhaust air purification system. The Montex stenter remains unmatched in terms of its robustness and long service life and with MonforClean technology, the waste heat from the drying process is used to pre-heat the drying air. This results in a radical reduction in the conventional heat supply required, compared to full gas and thermal oil heating. Overall energy savings of up to 40% can now be achieved compared to conventional stenters.

The first challenge at the Aue plant was how to fit the significantly larger machine into the available space without restricting the area required for docking operations.

The special multi-level configuration that Monforts designers and Curt Bauer’s team devised in order to meet these requirements involved raising all of the line’s drying zones – with a combined length of over 28 metres – on scaffolding platforms, to enable the ground floor space below them to continue to be fully utilised.

The next challenge involved configuring the MonforClean system without having to make any costly changes to the roofing structure. This, Gert Bauer observes, demanded “millimetre precision”.

With the new line now fully operational, the savings it is providing have yet to be fully calculated.

This year’s edition of ITMA ASIA + CITME proved to be a success for the exhibiting VDMA member companies. Measured by booked square metres, Germany had the largest contingent, among the foreign exhibitors. More than 40 VDMA member companies were exhibiting their innovative products in Shanghai.

Dr. Janpeter Horn, chairman of the VDMA Textile Machinery Association noted: “Although facing a difficult market situation, this year’s edition of ITMA ASIA + CITME has exceeded the expectations, both in terms of the number of visitors and the quality of the talks. The significant number of foreign visitors to the fair was particularly pleasing.”

Solutions were demonstrated for more sustainable textile productions by most of the exhibitors, and here the VDMA members presented their technologies for saving water, energy and raw materials under the heading “Smart technologies for green textile production.”  

Dr. Uwe Rondé, CEO, Saurer Intelligent Technology AG explained: “Saurer is satisfied with both the number of visitors and the quality of the discussions. Our booth was full from morning to evening with customers focused on latest technologies within the three mega trends: recycling, automation and digitalisation. Although machine utilisation in the spinning mills is still well below average, people are already gathering information and thinking about what to invest in once the market recovers.”

Benjamin Reiners, owner of Reiners + Fürst stated: „This year’s ITMA ASIA + CITME has exceeded our expectations by far. Especially the first day - a Sunday - has brought many high-quality customers and exclusively decision makers to our booth. We estimate about 20% international customers mainly from Bangladesh, Egypt, India, Iran, Pakistan, Uzbekistan and Vietnam. All customers agreed that the market situation at the moment is difficult, capacity usage is between 50-75% in the ring spinning sector and improvement is expected not before the 2nd half of 2024. Nevertheless the general spirit is very positive.“

“This ITMA ASIA was a great success for Trützschler. We welcomed a large number of Chinese visitors to our booth, as well as a significant number of interested international visitors”, said Dr. Bettina Temath, Head of Global Marketing Trützschler Group SE.

Georg Stausberg, CEO of the polymer processing solutions division and chief sustainability officer of the Oerlikon Group stated: „We can look back on a successful show where we were able to meet many of our customers not only from China, but also from Pakistan, India and Indonesia, for example.”

“A very well-attended trade fair, with interesting discussions, great innovative topics, in line with the modern and rapidly developing China" noted Wolfgang Schöffl, head of product line weaving machines and member of the extended management, Lindauer Dornier.

The VDMA Textile Machinery Association and VDMA China were present at the fair, to support the members e.g. with regard to IPR. With the help of a VDMA expert and a contracted law firm, the member company Sahm submitted a complaint application for patent infringement disputes during the exhibition to the onsite IPR office. Both parties, Sahm, and the Chinese company, that used patented design without permission reached an agreement: The Chinese company had to stop displaying functions and designs involving patent infringement on site which meant the removal of some structural parts and the covering of key components protected by patent protection.

Dr. Harald Weber, managing director of VDMA Textile Machinery concluded: “Asia, and China in particular, represent the primary foreign markets for the VDMA member companies in the sector. The Chinese market is the main destination for their exports. Other major export destinations in Asia include India, Pakistan, Bangladesh and Uzbekistan. ITMA ASIA + CITME provides a unique platform to showcase technologies for customers directly in Asia. The VDMA member companies are looking forward to the coming edition of the fair from 14 to 18 October 2024 in Shanghai.”

The latest survey of VDMA members' subsidiaries in China gives reason to hope that the economic situation in the Chinese textile industry could also improve significantly in the second half of the year. In addition, European textile machinery manufacturers are urged to be present on the most important market and at the trade fair and to offer Asian customers most advanced technology for their demanding challenges.

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.

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.

• Business situation remains poor and unchanged
• Manufacturers show prudence in forecasting future developments

 
According to ITMF’s Global Textile Industry Survey (GTIS) conducted in the middle of September 2023, survey participants exhibited a cautious sentiment regarding the current business situation. The indicator for the business situation stood at -27 percentage points (pp, see Graph 1) because companies in the entire textile value chain were struggling with rising costs and weak demand. Business expectations have remained unchanged since July at around +20 pp (see Graph 2). They have jumped into positive territory in January 2023 based on the assumption that the Chinese economy would give an additional boost, but this hope did not materialise. The analysis indicates that a hard landing of the global economy is not in sight.

Order intake recovered in May 2023, but flattened in July and remained very weak in September (-28 pp). The entire textile value chain is running on minimum levels of orders. As long as brands and retailers do not increase orders, the entire value chain will continue struggling. Order backlog slightly increased globally, from 1.9 months in July to 2.2 months in September 2023. This indicator had been on a falling trend since the end of 2021. The average capacity utilisation rate dropped again globally (69%). Textile manufacturers expect this rate to remain low in six months’ time as well.

Weakening demand has been the major concern in the global textile value chain for a year. In September 2023, this concern grew even stronger due to high inflation rates measured in the last few months, a phenomenon fueled by high energy and high raw material prices. Nevertheless, participants seem not to be concerned by order cancelations and inventory levels remain average along the textile value chain. 

ITM Exhibitions will open its doors to host "ITM 2024 International Textile Machinery Exhibition" from June 4-8, 2024. Preparations are in full swing for the organization, where textile technology leaders will bring the latest products together with their visitors for the first time.

The ITM team focused on advertising and promotional activities in order to host thousands of visitors and sector investors from all over the world at the ITM 2024 Exhibition, which halls were almost full due to intense participation demands. In this context; 'ITM 2024 Video', which tells the story of the increasing success of ITM exhibitions over the years and which is eagerly awaited by the whole sector, has recently been published. The video, which was published in Turkish and English on social media accounts such as YouTube, LinkedIn, Instagram, Twitter and Facebook, was viewed by more than 30 thousand people in total and received great appreciation from the viewers.

“Discover the Future!” in the video prepared with the main theme “Discover innovations, technologies, the future...” and including clues about the ITM 2024 Exhibition, was revealed as follows:
The textile sector is among the souls of the economy with its production capacity, export volume, and contribution to employment. Many R&D centers around the world and in Turkey are breaking new ground by taking their work and innovations one step further every day. Textile technology leaders are developing technologies that consume less water and energy, are easy to use, are software and automation supported, keep up with trends and respect the environment while doing so. Industry stakeholders, especially textile manufacturers, are now curious about the answer to this question: 'What will be the future of the textile industry, which is digitalizing, complying with sustainability principles, and signing groundbreaking innovations? This question will be answered at ITM 2024, which will host the latest innovations, technologies, artificial intelligence-supported machines, software and design excellence devices in textile machinery.

At this year’s Techtextil India, the Polymer Processing Solutions Division of the Swiss Oerlikon group will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Between September 9 and 12, the discussions at Jio World Convention Centre (JWCC), Mumbai, will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
The yarns used in airbags are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technol-ogies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants - without any loss of function in any climate and for the lifetime of the vehicle

Buckle up!
Seat belts have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments. “With our unique, patented Single Filament Layer Technology, we offer a sophisticated and simultaneously gentle high-tenacity (HT) yarn process for manufacturing these lifesavers and other applications made from industrial yarn”, explains André Wissenberg, Head of Marketing.

Road reinforcement using geotextiles
Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demand-ing tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC –  quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

In the first half of 2023, Rieter recorded a significant increase in sales of 22.2% to CHF 758.2 million, despite some cancellations or postponements of deliveries as a result of the earthquake in Türkiye. Cyclical market downturns in the individual market segments, which were already apparent in the second half of 2022, led to an order intake of CHF 325.0 million (-62.6%) in the reporting period, lower than in the corresponding period of the previous year.

Order intake in almost all regions was characterized by the reluctance to invest in new machines. Only in China did order intake increase due to investments by spinning mills in improving their local competitiveness. In addition, some customers held back pending investment decisions and waited for the innovations presented at ITMA in Milan in June 2023. At the same time, demand for consumables, wear & tear and spare parts declined due to the global market downturn.

On June 30, 2023, the company had a high order backlog of around CHF 1 100 million (June 30, 2022: around CHF 2 100 million). This therefore extends into the year 2024. As in the previous year, cancellations in the reporting period were around 5% of the order backlog, also impacted by the effects of the severe earthquake in Türkiye.

In the first half of 2023, Rieter posted a profit of CHF 25.2 million at the EBIT level, with an EBIT margin of 3.3% (first half of 2022: loss of CHF -10.2 million) and a net profit of CHF 13.3 million (first half of 2022: loss of CHF -25.2 million).

“Next Level” performance program planned
The challenging market situation over the past two years was marked by severe disruptions in the global supply chain in conjunction with rising material, energy, labor, and production costs. The current global demand for textile products remains at a low level. To increase long-term value for customers, employees, and shareholders, Rieter, as technology leader, is planning a performance program called “Next Level”. The goal of the program is to strengthen sales excellence, sharpen customer focus, improve cost efficiency in production and optimize fixed cost structures. The one-time cost of the program is anticipated to be around CHF 45 to 50 million, which will have an impact on the second half of 2023. Most of the program initiatives will be implemented before the end of 2023 with a view to achieving an expected impact from as early as 2024. With these measures Rieter is aiming to reduce operating costs by some CHF 80 million per year.

The program includes provisions for the net reduction of around 300 positions throughout the Group in relation to overhead functions. The possibility of further market- and volume-related adjustments in the order of 400 to 600 positions cannot be excluded. At the end of June 2023, Rieter had a global workforce of 5 555 employees.

Outlook
Given the economic situation and the ongoing cyclical market weakness, Rieter continues to expect below-average demand for new equipment in the coming months. A revival is not expected until the fourth quarter of 2023 at the earliest. Rieter also believes that demand for consumables, wear & tear and spare parts will not recover until later in 2023.

For the full year 2023, Rieter expects an EBIT margin of around 5 to 7% (including positive special effects of less than 2%) and sales at the previous year’s level of around CHF 1.5 billion.
