From the Sector

Groz-Beckert offers interested machine builders various cooperation opportunities to jointly develop new products or improve existing ones. In collaboration with Vanguard Pailung, a manufacturer of ultra-high-speed knitting machines for body-size products, Groz-Beckert has developed an innovative slider needle for a new generation of machines. Groz-Beckert's Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects.

In June 2022, Vanguard Pailung approached Groz-Beckert with a cooperation request. Together with Groz-Beckert, the company wanted to develop a new needle solution for an innovative ultra-high-speed machine. Together with an innovative slide needle, the new machine was to exceed the speed and productivity of known knitting systems of large circular knitting machines.

Machine and needle development ran in parallel and were closely coordinated. The first field tests took place in the Vanguard Pailung laboratory in Monroe/NC, USA in February 2023. The successful development was presented to a wide audience for the first time at ITMA 2023 in June.

Unlike latch needles, slide needles do not form the stitch via a needle latch, but via a slide that is controlled by its own channel. The advantage of this is that the needle can withstand high speeds, as there is no latch impact, which in turn increases productivity.

The use of the new slide needle in ultra-high-speed machines ensures a particularly high level of process reliability. With the new needle variant, the closer is guided safely and precisely in the groove in the needle shank. At the same time, the base of the needle shank is closed, which ensures maximum stability. The slider needle reliably prevents the so-called latch impact and thus makes a decisive contribution to process reliability. Its use ensures a uniform and speed-independent loop structure, even at maximum speeds.

Mayer & Cie. CN Changzhou LLC, the Chinese subsidiary of the German circular knitting and braiding machine manufacturer Mayer & Cie., settled in Jiangsu Province at the beginning of the year. Until now, the Sales & Service subsidiary Mayer & Cie. China, founded in 2003 and later to become Mayer & Cie. China, had been based in Shanghai.

The new location within a Sino-German Innovation Park comprises a production hall of around 5,000 square meters. In the future, the circular knitting machines assembled for the domestic market will increasingly consist of locally sourced parts and components from various suppliers.

Since 2011, Mayer & Cie. has been assembling selected machine types for the domestic market at its Chinese plant in Shanghai. It started with a single jersey machine for the most common requirements. Today, China's domestic portfolio includes four types of machines. Until now, the knitting heads for these circular knitting machines had been pre-produced at the Mayer & Cie. plant in the Czech Republic and then transported to China.

The manufacturer is now saying goodbye to this "knitting head principle". It made perfect sense for the start of the assembly line, says Benjamin Mayer, managing partner of Mayer & Cie. However, it leaves little room for flexibility. He explains: "In the future, we will source all parts and components of the machines assembled in China from various local suppliers. This allows us to offer our local customers more attractive prices and faster delivery times with the same quality standards. We expect this change to improve the positioning of our products in the domestic market." In addition, the new plant will be connected to the parent company in Albstadt via an SAP connection. This was imperative to increase efficiency, transparency and quality.

The new headquarters of Mayer & Cie. CN is the German Chinese Innovation Park in Jintan in Jiangsu Province. The companies based there enjoy various advantages, including attractive location costs as well as proximity and exchange with other German companies on site. In addition, the administration of the SGIP supports companies in their search for employees, suppliers and service providers.

In the fourth quarter of 2023 Italian textile machinery orders index, drawn up by the Economics Department of ACIMIT, the Association of Italian Textile Machinery Manufacturers, appears to be stationary compared to data recorded for the same period in 2022. In terms of absolute value, the index stood at 82.4 points (basis: 2015=100).

This is the result of an upswing in orders from foreign markets, counterbalanced by declining orders on the domestic front. While orders in Italy decreased at 18% rate, a 4% increase was observed abroad. The absolute value of the index on foreign markets amounted to 77.9 points, whereas it came in at 126.2 points domestically. Overall for the fourth quarter, the average order backlog yielded 3.7 months of assured production.

For the whole 2023 year, the index declined 25% overall compared to the 2022 average (absolute index of 82.4). On the home front however, the index dropped 24% (absolute index of 124.5), while slipping 25% abroad (absolute index of 78.4).

ACIMIT president Marco Salvadè commented the data: “The orders index for October – December 2023, as elaborated by our Economics Department, confirms an intake of orders that is still weak, with a negative trend in demand for machinery that is ongoing for the domestic market.” Nonetheless, the orders index abroad shows a slight increase. “We estimate that the global geopolitical context is still a source of concern,” continued Salvadè, specifying that, “For the first nine months of 2023, Italian exports on major global markets (i.e. China, Turkey, India and the United States of America), confirm a widespread decline. However, some positive signs emerged in the fourth quarter of last year, as reflected by the latest orders index. For 2024 we expect a consolidation of this trend reversal.”

In a judgment in December 2023, the Supreme People’s Court of the People’s Republic of China ruled in favor of Rieter in a legal dispute. The case concerned the infringement of a Rieter patent by a competitor’s draw frame. Rieter protects its innovations with patents and registered designs and consistently takes action against infringements of its intellectual property.

Rieter draw frames are known for their stable operation with high sliver quality and productivity. Scanning precision and autoleveling dynamics ensure outstanding sliver evenness and thus the production of high-quality yarns. Draw frames have also been the subject of a patent litigation by Rieter in China at various levels of jurisdiction. Rieter had sued a competitor for unauthorized use of its patented draw frame technology.

In the summer of 2022, the Shanghai Intellectual Property Court confirmed the patent infringement identified by Rieter and prohibited the accused competitor from continuing to use Rieter’s patented technology. The infringing party was also ordered to pay damages to Rieter.

The culpable competitor then appealed the decision of the Shanghai court to the Supreme People’s Court of the People’s Republic of China.

In December 2023, the Supreme Court of China in Beijing upheld the Shanghai decision, confirming that the patent had been infringed. As a result, Rieter’s competitor is prohibited from selling the infringing machine types and is required to pay the damages determined by the court.

This Supreme Court decision represents a major success for Rieter in defending its proprietary technologies in China. It is further proof that foreign companies can effectively defend their intellectual property in China.

As the technology leader in spinning machinery manufacturing, Rieter invests around 5% of its turnover annually in research and development. Rieter protects its innovative products with patents and registered designs and takes consistent action against infringements of industrial property rights.

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.

Lectra will now directly manage the production of its cutting equipment manufactured in China, primarily dedicated to its Asian customers. The Suzhou site, located to the west of Shanghai, will thus benefit from the standards of operational excellence already implemented by Lectra at its two other plants in Bordeaux-Cestas, France, and Tolland, USA.

Lectra's teams have over 35 years’ experience in the Asia-Pacific region, which in 2022 generated 25% of the Group's revenues.

Since the acquisition of its competitor, Gerber Technology, in 2021, Lectra had been relying on a plant belonging to Dutch group VDL Groep (VDL), to manufacture Gerber-brand multi-ply cutters and spreaders.

For its industrial activities, Lectra aimed to adopt the same standards of operational excellence in China as those currently in effect at its Bordeaux-Cestas and Tolland sites. The Group therefore created a new subsidiary, Suzhou Lectra Equipment Manufacturing Co. Ltd., to take over from subcontractor VDL as of December 1, 2023.

Following the takeover of in-house production at the Tolland site in October 2022, the creation of the Suzhou Lectra Equipment Manufacturing Co. Ltd. subsidiary marks a new milestone in the deployment of Lectra's industrial excellence strategy on a global scale. The Group intends to give priority to regional industrial production, which is beneficial to the local economy.

Together with the German circular knitting machine builder Mayer & Cie., Groz-Beckert has developed the optimized Relanit sinker SNK F over the past years. Independently of this, the development of the new LCmax™ energy-saving needles took place. The focus of both developments is on efficiency, energy savings and increased process reliability.

Groz-Beckert offers interested machine builders different cooperation options to jointly develop new products or optimize existing ones. The Groz-Beckert Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. At the ITMA in Milan in June 2023, Groz-Beckert presented some of the successful cooperations under the motto "Innovation through cooperation". Among them were two new developments realized with Mayer & Cie. Groz-Beckert presented the two new products for the first time in Asia at ITMA Asia in November 2023.

Optimized Relanit sinker SNK F
At the end of 2018, circular knitting machine manufacturer Mayer & Cie. approached Groz-Beckert with a request to jointly develop an improved and more efficient sinker for selected machines of their Relanit family that would run more smoothly and reliably in the needle tricks. The innovative sinker has an integral spring with a spring force that is adapted to the sinker thickness. Field tests were consistently successful and confirmed the functionality and advantages of the new sinker.

Thanks to their adapted spring, the newly developed SNK F Relanit sinkers are securely guided while they are running through the cam track, resulting in a quieter operation. This increases process reliability and ensures an improved loop structure. In addition, wear on the swivel butts of the sinkers is reduced. This increases service life and makes the process more sustainable and cost-efficient.

Higher energy efficiency thanks to LCmax™
The objective second recent cooperation with Mayer & Cie. was to develop a cost-effective energy-saving needle. After considering various variants, the common choice of Mayer & Cie. and Groz-Beckert was the LCmax™ knitting machine needle with innovative, wave-shaped shank geometry. The first prototypes were extensively tested on laboratory machines at Groz-Beckert's TEZ.

The wave-shaped shank of the LCmax™ needle ensures a smaller contact area of the needle in the needle trick. This results in less friction, which reduces machine temperature and enables energy savings of up to 20 percent compared to a standard needle. This saves costs and at the same time allows operation of the machine at the maximum possible speed.

In both projects, the cooperation between Mayer & Cie. and Groz-Beckert went far beyond mere product development. In addition to Applications Engineering and Construction, the companies' Sales and Purchasing departments were also involved in a close exchange.

Mahlo GmbH + Co. KG will present its systems and solutions for efficient and high-quality textile production and finishing together with Shanghai Kuantex at ITMA Asia (November 19 and 23). The focus will be on the machine manufacturer's new straightening concept, the Orthopac RXVMC.

"In the new straightening concept, special attention was paid to the straightening mechanics and their interaction with the analysis electronics of the probe system," explains Sales Manager Thomas Höpfl. The control concept is also new. A probe group at the leveler infeed detects distortions even before they reach the correction rolls. In this way, the rolls are brought directly into position and the fabric is corrected from the very first centimeter. A scanner group at the outfeed also detects possible residual distortion, which is corrected at the second straightening module. This enables an even more precise and faster response when it comes to reacting to rapidly changing distortions. The Orthopac RXVMC therefore shows its full strength when straightening knitwear and fabrics sensitive to distortion.

Also contributing to high-quality textile production and finishing is the Famacont PMC for controlling weft and stitch course density, which will also be on show at ITMA Asia. The Famacont PMC-15 uses a sensor to measure the yarn or stitch density and compares it with the target value stored in the recipe data management system. The detected deviation of the yarn density from the target value is used to fully automatically regulate the leading during the needling process on the stenter frame. Interested parties can have the mode of operation explained to them at the Mahlo booth with the help of a demo tower and their own or provided fabric samples.

Another major topic remains Industry 4.0, because the best measured data is of no use if it cannot be utilized. Mahlo has continuously developed its digital environment mSmart. "Our systems generate data that the customer can use immediately to regulate goods on-line. At the same time, all measured values are backed up in our data management system mLog enhanced and can be retrieved at any time. With this historical data, processes can be optimized and weak points in the process can be minimized," explains Sales Manager Thomas Höpfl.

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.

After four decades in the packaging industry, the Manjushree Group is entering the Indian nonwovens market. The entrepreneurs rely on a flexible RF Smart Composite line from Reifenhäuser Reicofil to meet very different customer requirements.

The Manjushree Group operated a blown film line for packaging materials for the tea industry in the eastern part of India as early as 1983. In the years that followed, Manjushree Technopack Ltd. developed into one of the largest suppliers of solutions for rigid plastic products in South Asia - and the family business grew into a group with several business segments. In 2018, the entrepreneurial family repositioned itself: it sold its previous core business to a financial investor and established Manjushree Ventures with footholds in start-up financing, real estate business, and manufacturing - the largest of which is Manjushree Spntek as a producer of high-quality spunmelted fabrics.

Since February 2023, Manjushree Spntek has been producing high-performance spunmelts on an RF Smart Composite line from Reifenhäuser Reicofil - benefiting both from many years of experience in the packaging industry and from experience with Reifenhäuser's blown film lines. "We know a lot about plastic extrusion, for example when it comes to line operating parameters such as temperature and pressure. Processing is similar in both industries," explains Rajat Kedia. "The main difference is the distribution of the products: In plastic packaging, we had an established customer base and sold a lot of material to the big consumer goods manufacturers. The nonwovens market in India, on the other hand, is still forming, with thousands of small companies currently getting involved." These serve customers in their regions, such as hospitals.

The RF Smart Composite line is a standardized spunmelt line for smaller and emerging markets. The line produces nonwovens of the highest Reicofil quality with appropriately adapted throughput. This makes it ideally suited for applications in hygiene and medical technology and, with typically 8,200 annual production hours, it is extremely reliable. In addition, operators can start production quickly because in many cases the line can be integrated into existing buildings.

Before production could start, Manjushree built a new production building in Bidadi, a town an hour's drive from Bangalore International Airport. The building is designed to be sustainable: It uses natural light and fresh air, has comprehensive contamination control, and obtains almost all of its energy from renewable sources. Reifenhäuser Reicofil then installed, commissioned and tested the RF Smart Composite line.

Since February 2023, Manjushree Spntek has been producing high-quality spunmelted nonwovens, including ultra-soft fabrics and fabrics with special coatings for customers in the hygiene and medical industries. The material can be used, for example, for baby diapers and feminine hygiene products, but also for medical articles ranging from surgical gowns to surgical drapes.
