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.

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.

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. The deployment of both parties' latest innovation practices, textile automation offerings, integrated enterprise services, C2M solutions, and a platform for designers "Materialliance", will allow Santoni Shanghai and Terrot to connect and bridge demand and offer of circular knitted products.

By incorporating Terrot's offerings, particularly in the double jersey and jacquard sector, Santoni stands to gain a competitive edge in offering machines known for their performance, low maintenance, and cost-effectiveness. Highlighting this shift is Terrot's UCC 572-T, a transfer jacquard machine for sports and leisurewear.

Following the acquisition, Terrot will continue to operate under the leadership of managing directors Robert W. Czajkowski and Dirk Lange. Santoni plans to maintain Terrot’s headquarters in Chemnitz, Germany, along with its facilities, brands, and practices.

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.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan will participate in the A+A 2023—Safety, Security and Health at Work International Trade Fair in Düsseldorf, Germany (24th-27th October 2023). On display will be the company's latest safety-related technology through its new SPG®-R pile glove knitting machine and the prototype SFG®-R next-generation glove knitting machine. Each of these machines drew attention at SHIMA SEIKI's booth at the International Textile Machinery (ITMA 2023) Exhibition in Milan.

SHIMA SEIKI's original SPG®, developed in 1979 as the world’s first automatic glove knitting machine to produce seamless pile-knitted gloves, is now reborn as a next-generation model. Pile gloves feature special traits that include cushioning, shock-reduction and thermal insulation and cold protection, making them popular especially in the field of industrial safety. Now, SPG® is redesigned from the ground up and re-introduced as the SPG®-R. The new SPG®-R features a new moveable sinker system with selectable loop presser function. Combined with a new belt-driven carriage it allows SPG® to provide efficient and reliable production of fashionable, high-quality pile gloves. Shown in 7 gauge at A+A, SPG®-R surpasses the previous generation with pioneering technology, improved capability and reliable productivity.

SHIMA SEIKI's original product on which the company was founded was the fully automated seamless glove knitting machine. While the original model evolved to become the current SFG® series, SFG®-R exhibited at A+A is its spiritual successor. With a new sinker system, a belt-driven 2-cam carriage and auto yarn carriers SFG®-R is a completely new machine for knitting gloves that conform better to the shape of the hand for improved fit. Furthermore its greater design potential offers users the opportunity to break out of the work glove market and into the fashion market. SFG®-R is shown as a prototype next-generation model in 12 gauge at A+A.

Also demonstrated will be SHIMA SEIKI's APEXFiz® design software. The importance of design software is made even more significant by the new patterning capabilities of SPG®-R and SFG®-R. Both machines now feature increased design potential that allow each of their products—pile gloves and work gloves, respectively—to expand their market into fashion. APEXFiz® is available for developing these designs. Furthermore virtual sampling on APEXFiz® is especially effective in streamlining the production process. Ultra-realistic simulation capability allows the use of virtual samples for evaluating design variations without producing actual samples for each variation, thereby minimizing the time, cost and resources normally required with sample-making, supporting smart, speedy and sustainable production.

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.

Carbios inaugurated its textile preparation line at its demonstration plant in Clermont-Ferrand, in the presence of Mr. Lescure, French Minister for Industry. To streamline the textile preparation phase, which is currently carried out by hand or on several lines, Carbios has developed a fully integrated and automated line that transforms textile waste from used garments or cutting scraps into raw material suitable for depolymerization with its enzymatic biorecycling process. This patented line integrates all preparation stages (shredding and extraction of hard points such as buttons or fasteners), and provides Carbios with a high-performance, scalable development tool. The platform will help validate the biorecycling technology for textiles at demonstration plant scale (by 2024), and provides Carbios with expertise in working with collection and sorting operators to specify the quality of textiles and the preparation steps needed to make them suitable for enzymatic recycling. This expertise will also be invaluable to brands in the eco-design of their products.

Current collection, sorting and preparation infrastructures limit the amount of textile waste available for “fiber-to-fiber” recycling. Collection rates average around 15-25% worldwide^[1], and much of the waste collected is exported to Africa, Asia or Latin America for sorting.

Moreover, textiles are highly complex materials, with yarns of different composition (or nature) that are difficult, if not impossible, to physically separate. However, the highly selective enzyme developed by Carbios can specifically depolymerize the PET (polyester) present in textile material.

At present, textiles are sorted and prepared mainly by hand, with low yields, particularly for disruptors to recycling processes such as “hard points” (zips, buttons, etc.). To optimize this crucial phase, Carbios is contributing a textile preparation solution to accelerate the development of biorecycling in the textile industry. Enzymatic recycling, or biorecycling, therefore contributes to the construction of a textile recycling chain and the acceleration of textile circularity, also enabling brands to do away with used bottles.

Through continuous research and development, the company offers innovative, high-quality nonwoven solutions across various sectors, including hygiene, medical, personal care, textiles, filtration, and agriculture.

Members of TMAS – the Swedish Textile Machinery Association – will be taking part in the forthcoming ITMA Asia + CITME exhibition, taking place from November 19-23 2023 at the National Exhibition and Convention Centre in Shanghai, China.

Weaving
In the area of weaving, 93% of the 114,000 new looms delivered in 2022 went to Asia, according to the latest figures from the International Textile Manufacturers Federation (ITMF), with China the top destination, followed by India.
As a result, TMAS members like Vandewiele Sweden AB and Eltex have a huge market to address that has been established over many decades.

Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of the market-leading Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

Yarn and sewing thread monitoring
With nearly 70 years of expertise in yarn sensor technology, Eltex of Sweden AB has been at the forefront of new product development. Its EYE and EyETM systems are capable of accurately and efficiently monitoring the movement and tension of more than 1,000 yarns simultaneously. These systems are suitable for various applications and fibre types, including warping, winding, multiaxial weaving and new material applications.

Eltex sewing tension monitors, such as the ETM422, have been well-received by customers. This device can monitor the tension of sewing threads in real time, effectively improving the quality and safety of sewn products. Particularly in China's rapidly growing automotive manufacturing sector, the ETM422 has seen widespread use to meet the industry’s escalating demands for product safety and quality.

Dyeing and finishing
“Digitalisation, automation and AI have become the key enablers for sustainable gains across the entire textile industry and so much has been achieved in the past few years, especially in terms of automation,” says TMAS secretary general Therese Premler-Andersson. “One area in which TMAS members are really making a difference right now, is in replacing water and energy-intensive technologies for the dyeing and finishing processes with new digital technologies.”

The TexCoat G4 non-contact spray technology for textile finishing and remoistening, for example, will be showcased in Shanghai by Baldwin. It not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to a customer’s requirements in terms of single and double-sided finishing applications. The TexCoat G4 can reduce water consumption by as much as 50% compared to traditional padding application processes.
