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.

Since March 1st 2024, the technical centre of Institut für Textiltechnik of RWTH Aachen University (ITA) has been equipped with an additional winder.

This globally unique winder has been manufactured by Comoli Fermo S.r.l, Paruzzaro, Italy, and enables the development of elastic yarns for numerous and innovative areas of application. Monofilament and multifilament yarns can be spun within a speed range of 100 to 3,200 m/min on bobbins with an industrial standard size of 73.6 mm x 83.8 mm x 115.5 mm.

The use of these bobbins enables immediate further processing along the textile process chain, for example in production of elastic combination yarns or knitting. Due to the high flexibility of this winder in combination with the available spinning plants at ITA, testing is possible with material amounts starting from a few hundred grams up to hundreds of kilograms.

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%.

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.

Mahlo GmbH + Co. KG will participate in the Colombiatex textile show, held in Medellin from 23 to 25 January. This year, Mahlo will be joining forces with Brückner Textile Technologies to present their solutions for the textile production sector at their joint booth.

Both companies appreciate the power of Colombia’s textile industry. Textile is one of the most important industrial sectors in the Latin American country with an export value of clothing of more than 600 million US dollars. The United States are also the main export destination for apparel products. At Colombiatex 2024, Mahlo's Head of Sales, Thomas Höpfl, will be present to share insights and discuss how Mahlo’s innovative technologies can address the specific challenges faced by Colombian textile manufacturers. Sustainability of process efficiency being among the most pressing ones.

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.

Santoni Shanghai Knitting Machinery Co., Ltd. announces that it has received regulatory approval from Chinese authorities for its proposed acquisition of Terrot GmbH, a manufacturer of circular knitting machines in Germany.

The acquisition represents a pivotal step in Santoni's strategy to advance the circular knitting machine industry. The integration of Terrot into the Santoni ecosystem is projected to increase Santoni's production capacity and boost its market share, and in conjunction with other strategic objectives, firmly solidify Santoni's position as the leading manufacturer in the industry, with unrivaled scale, depth of innovation and expertise.

Seeking to meet rising demand for high-end circular knitting products, Santoni has pursued an Ecosystem Strategy in recent years, aiming to unify a highly fragmented industry and enhance innovation, sustainability and digitalization to more effectively meet market needs.

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.

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.

A delegation of Italian textile machinery companies will attend the 2023 edition of TITAS TAIPEI, which will be held in Taipei, Taiwan, from October 17 to 19, 2023. Taiwan is judged as a very promising market for the Italian textile machinery industry, especially in the innovative sectors of technical textiles and nonwovens.

In 2022, Italian exports to the Asian country exceeded the value of 17 million euros, and in the period January-June 2023, the value has already reached 7 million euros. The attention for the Taiwanese market has led ACIMIT, the Association of Italian Textile Machinery Manufacturers, and Italian Trade Agency to set up a pavilion at the upcoming edition of TITAS TAIPEI.

Six Italian textile machinery manufacturers, all ACIMIT member companies, will exhibit in the pavilion: Ferraro, Danitech, Lgl, Ms Italy, Reggiani, Unitech.

At the upcoming TITAS TAIPEI, therefore, visitors will be introduced to Italian technology, once again a key player in the textile production process.
