From the Sector

High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.

TEXO AB, a member of TMAS, the Swedish textile machinery association, is currently seeing a surge in demand for its Compfelt weaving looms for press felt base fabrics.

“These are far from standard machines,” explains TEXO President Anders Svensson. “Off-the-shelf industrial weaving machines generally range in their working widths from 1.9 to 3.2 metres, with those purpose-built for technical applications such as geotextiles extending to wider widths of six metres and beyond. Meanwhile, one of the machines we have recently successfully delivered and commissioned has a working width of 23 metres and is not even the widest of the many such machines the company has engineered and delivered worldwide since its formation.”

A second recently-delivered line has a more modest working width – in relative terms – of 13 metres.

Paper machines
The demand for such machines comes from the suppliers of paper machine clothing (PMC) to paper mills, who in turn operate colossal machines for paper manufacturing.
On of the largest paper making machines is currently believed to be located on Hainan Island off the southern coast of China and is 428 metres long – roughly the length of four football pitches. Naturally, such machines require equally large-scale components, which is where TEXO comes in. All paper machines require a regular supply of PMC fabrics which are employed in three separate areas of the paper machine – the forming section, the press section and the drying section.

Press felts
TEXO Compfelt weaving machines are specifically employed for the production of endless (tubular) woven base fabrics for the press section of paper machines, where water is mechanically removed from the newly formed sheet of fibres. In the simplest press, the sheet is carried by the PMC fabric between two rolls, where water is squeezed out by the application of load and pressure. This can also be assisted by the use of vacuum and heat. The PMC fabrics here need to be replaced regularly, with a maximum lifespan of six months.

Press felts have become increasingly sophisticated over the years, consisting of complex woven base structures which are subsequently combined with nonwovens via needlepunching on equally huge machines. The woven base fabrics are primarily made from polyamide for its strength and hygroscopic and elastic properties.

Dobby harness
“A major refinement of the machine has been the ability to equip it with up to 24 dobby harness frames to meet the demand for sophisticated structures from the PMC manufacturers. Although the PMC business represents a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.”

Another significant development has been that of a self supporting base pre-filled with concrete, which has eliminated the need to dig out foundations in a plant to support the machine.

Retrofits
TEXO’s looms are built to last, but technology moves forward, and the company is also currently active in the retrofitting of existing machines built as far back as the 1970s.

Integration
TEXO has also just integrated its offices and production centre at its base in Älmhult, Sweden, to create a unified 5,000 square metre site.

• Patterning from the cloud
• SwapKnit – KARL MAYER's first Smart Machine function revolutionizes the way of guide bar control

A view of machine data from anywhere and at any time, service support as if on site but from far away, patterning from the cloud: digitalization offers completely new possibilities in warp knitting, which KARL MAYER is using to offer its customers a wide range of advantages for their business.

• The Green Revolution: How Microfactories Can Change the Face of Fashion by Mark Sollman, Product Manager EMEA, Mimaki Europe

With the all-important COP26 Climate Change Conference having taken centre stage in November, there is no time like the present for the fashion world to rally together in stepping up sustainability efforts and getting carbon emissions under control. Globally, the fashion industry is now estimated to account for around 10 percent of greenhouse gas emissions and 20 percent of wastewater , making the pursuit of greener production methods more pertinent than ever before. Thankfully, we are seeing a new era of production enter the fashion arena, with the increasing emergence of technologically advanced, highly automated microfactories.

Along with reducing unnecessary waste through on-demand production, microfactories have a smaller ecological footprint than traditional garment production and require no water use during the production process, making it not only a faster solution, but a greener one too.

Last year’s FESPA saw Mimaki team up with fashion designer Carolina Guzman to bring her designs to life in real time at the show, setting up its own working microfactory live on-site to take her designs from screen to garment within just a day. Guzman’s designs were created using Mimaki’s TS100-1600 Sublimation Printer, before being transferred to textile, digitally cut and finally pieced together. Devised with a string of ethical and environmental objectives threaded throughout, the microfactory also exclusively utilised eco-friendly Greentex fabric, and any remaining material was donated to Sheltersuit: a wind- and waterproof coat that can be transformed into a sleeping bag, which is provided free of charge to homeless people and refugees.

Through working with a number of strategic partners – including transfer printing expert, Klieverik; paper solutions specialist, Neenah Coldenhove; and digital cutting equipment provider, Summa – Mimaki was able to produce a collection of unique, high-quality garments live on the stand during the tradeshow, demonstrating to visitors from more than 100 countries some of the key reasons that microfactories seem set to change the future of fashion…

Unparalleled speed and versatility
Where traditionally, apparel manufacturing has centred on a production chain model of sourcing materials and producing garments in bulk, microfactories are now enabling on-demand, on-location production, making it possible to create everything from unique, one-off pieces and samples right through to entire product lines – all at unprecedented speeds. This means greater flexibility and customisation, enabling designers to modify or update designs and respond to market trends as they occur.

Simplified supply chains and minimised risk
The microfactory setup brings production in-house and on-demand, minimising the cost of not only storing stock, but also of shipping it and responsibly disposing of unsold items. Where recent geopolitical events have highlighted the fragility of global supply chains, microfactories offer a unique independence from these systems, empowering garment manufacturers to future-proof their businesses, become less reliant on external systems and suppliers, and reduce the risk of disruptions.

A boosted bottom line and a greener future
Facilitating savings in a whole line of resources, from physical storage and production space to time and energy, microfactories ultimately have the potential to significantly increase profitability for garment manufacturers, with the additional benefit of being easily scalable as production increases. Perhaps even more compelling, however, are the environmental considerations. Demonstrated on a small scale through Mimaki’s recent project, the environmental benefits inherent to microfactory production will have an even greater impact as it becomes more prolific and commonplace throughout the fashion world, with the potential to effect meaningful environmental change as adoption increases in the years to come.

During an expansive, three-day Electronics For Imaging, Inc. open house this month at the company’s EFI™ Reggiani industrial textile printer facility, textile and apparel manufacturers witnessed first-hand the market-leading innovations that provide users with new opportunities. The December open house, which drew more than 70 attendees from over 23 different European, South American, and Middle Eastern countries, featured informative sessions with product experts on a diverse range of topics, covering new and trending market applications for textile manufacturers.

Attendees witnessed live demonstrations of eight advanced digital printers during the open house, including the new EFI Reggiani HYPER, EFI Reggiani TERRA Silver scanning/multi-pass printer, and EFI Reggiani BLAZE as well as the EFI Reggiani BOLT – the award-winning single-pass offering that is the one of the fastest digital textile printers.

EFI Reggiani HYPER – a fast scanning digital printer
The new EFI Reggiani HYPER is a scanning printer available in 1.8-metre, 2.4-metre or 3.4-metre widths. The Reggiani HYPER model targets the industrial high-speed segment of the multi-pass textile printing sector.

With an up to eight-colour configuration, it prints at speeds up to 13 linear metres per minute in two-pass production mode. The new printer is suitable for high-quality production on knitted or woven fabrics and is designed with smart technology that enables it to be integrated into Industry 4.0 projects.

Sustainable direct-to-textile printing with the EFI Reggiani TERRA Silver
The new-version TERRA Silver printer is part of EFI’s complete TERRA line-up of pigment ink printer solutions. It allows print service providers to enter the world of industrial textile with a short, smart and green production process.
The printer also features:

• A new recirculating ink system for superior reliability and minimum maintenance
• Several printing modes to ensure maximum flexibility in terms of design capability
• New, real-time image processing that eliminates time spent in image pre-calculations
• A user friendly, intuitive interface
• A more-efficient polymerisation process that takes place as printed textile goes through the printer’s on-board dryer.

EFI Reggiani BLAZE, an ideal entry solution for industrial textile printing
The EFI Reggiani BLAZE printer is designed to give textile companies the opportunity to enter the digital textile printing market with a compact solution. The new, 1.8-metre-wide printer offers an innovative, low-maintenance, continuous recirculation ink system equipped with a level sensor and degassing as well as a print head crash protective system for longer printhead life and superior uptime.

The upgraded EFI Reggiani BOLT – one of the fastest digital textile printers
In 2021, the EFI Reggiani BOLT received a combination of hardware and software enhancements that minimise artifacts, compensating for missing nozzles that may occur over time and enhancing uniformity to deliver smoother solid colours. The upgrade also delivers improved quality and smoother gradients, plus it enables faster printhead replacement and drastically increases file processing speed by up to 200% for large, complex files.

Comber machines from Trützschler are already trusted by customers across the textiles industry and around the globe. The TCO 21 is the latest addition to their portfolio and was built to boost productivity,  ensure quality and support increased automation.

High productivity and raw material savings
One of the key benefits of the TCO 21 is its advanced processing speed. This next-generation combing machine is able to produce at a rate of up to 600 nips per minute. the TCO 21 can also be coordinated with Trützschler’s JUMBO CANS (Ø 1.200 mm). They not only reduce yarn defects due to fewer piecings which leads to quality improvements, but also offer a higher efficiency because of their larger dimensions. This, for example, has positive effects on the number of necessary cans and can transports – and results in lower personnel costs.

Excellent yarn quality
The TCO 21 comes with COUNT MONITORING as standard. This feature makes it possible for the machine operator to define limits for count variations via an easy-to-use display. Trützschler’s DISC MONITOR system of sensors measures the count continuously, and the machine alerts the operator and switches off if the limit is exceeded. In addition, the COUNT MONITORING function also includes spectrogram analysis.

Customers can further strengthen their focus on quality by choosing to add the COUNT CONTROL function to the TCO 21. It is managed via the same easy-to-use display, and offers automatic sliver count measurement, as well as spectrogram analysis. It also automatically regulates the main draft during production to balance count variations and ensure the desired sliver count. This feature is particularly attractive for customers who manufacture blends of cotton and synthetic, as it can also be used to avoid variations in the overall yarn composition.

Automatic optimization
The TCO 21 joins the TCO 12 from Trützschler as an combing machine that offers automatic PIECING OPTIMIZER technology, and that finds the right piecing setting without a single laboratory test, because of two functions: First by adjusting the piecing time in the combing cycle (timing function). Whereas the resetting of the detaching point (piecing time) is usually a very time-consuming task, it now takes only a few minutes and is performed automatically at a push on a button. Second the customer is helped to select specific detaching curve types (curve function) for their unique requirements.

Easy operation
The TCO 21 is simple to operate and maintain. The SMART TOUCH display is fast and intuitive, and a Radio-Frequency Identification (RFID) sensor quickly identifies each user and adapts the information on the display to their individual needs. The multi-colored T-LED display provides visual indications of the machine’s status or quality parameters over large distances which enables the operator recognizing them at a glance in the entire spinning mill. The TCO 21 is built with original Trützschler electronics that ensure high performance and durability: Their intelligent cooling system, that has already proven itself in the draw frame TD 10, contributes to a longer service life by reducing the operating temperature of electronic power components. Even if components have to be replaced at some point, the customer can keep their spare parts inventory small, because they can switch also electronics spare parts flexibly between different machine types, e.g. cards and draw frames. The option to add an automatic greasing function completes the easy operation of the TCO 21.

International technology group ANDRITZ will present its innovative nonwovens and textile technologies at the booth of its Indian representative PRN Techtex at Techtextil India 2021 in Mumbai, India, from November 25 to 27, 2021. A special focus will lie on its technologies for air-through bonding, needlepunch, textile recycling, and processes for biodegradable wipes, like spunlace and WetlaceTM.

Air-through Bonding
Air-through-bonding lines are the preferred choice for producing nonwovens with the best quality of softness and bulk for acquisition distribution layers, top sheets, and back-sheet products. With ANDRITZ carding machines and the new flat belt oven, customers benefit from high-performance fabrics from 16 to 80 gsm, produced with bicomponent fibers. Several Chinese customers have already invested in ANDRITZ aXcess carding machines, which provide perfect web uniformity. In addition, the CETI (European Center for Innovative Textiles) in Lille, France, has installed an air-through-bonding oven from ANDRITZ.

Textil-recycling Technologies
Recently, ANDRITZ acquired Laroche SAS, a leading supplier of fiber processing technologies such as opening, blending, dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. The product portfolio further complements and increases the ANDRITZ Nonwoven product range. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses.

Needlepunch Technologies
Driven by the dynamic market for durable nonwovens, ANDRITZ has developed an elliptical pre-cylinder tacker – the PA3000. With this modern machine, ANDRITZ is responding to customer demands for higher capacities and lighter products. The PA3000 is an optimized cylinder pre-needleloom, which offers greater speeds and widths and has been specially developed for lighter webs. There is no friction between the web and the rolls, and there are no issues with the visual appearance.

ANDRITZ is also focusing on its latest needling technology for producing veloured felts, mainly for applications in the automotive industry.

In addition, ANDRITZ will be presenting the next generation of its batt-forming technology, the ProWin system. ProWin is a further development of ProDynTM and ProWidTM, which have achieved a high level of acceptance on the market with around 200 systems installed. This technology improves the current weight-profiling options and increases the actual production capacity.

Production of Bio-Wipes
For many years now, ANDRITZ has offered different nonwoven processes, such as spunlace and Wetlace, with one goal in mind: reduction and elimination of plastic raw materials while maintaining the high quality of the desired product properties. The latest development in this field is the ANDRITZ neXline wetlace CP line. This is a fully engineered production line, combining the benefits of wetlaid and drylaid technologies to produce a new generation of biodegradable wipes. This process achieves high performance entirely with plastic-free raw materials. The added benefit of using a blend of fibers, like wood pulp, short-cut cellulosic fibers, viscose, cotton, hemp, bamboo, or linen, without chemical additives, results in a 100% sustainable fabric.

Members of TMAS – the Swedish textile machinery association – are proving instrumental in pioneering new sustainable processes for the dyeing, finishing and decoration of textiles.

The wasteful processes involved in these manufacturing stages are only one component in the development of viable circular supply chains for textiles that are now being established in Sweden.

At the recent Conference on Sustainable Finishing of Textiles, held across three separate afternoons on September 30^th, October 1^st and October 7^th, delegates heard that Sweden will introduce extended producer responsibility (EPR) for waste textiles and clothing at the beginning of 2022, ahead of the adoption of a similar European Union-wide EPR system in 2025.

New fibers
Swedish companies are also active in the development of new fibers derived from waste clothing, building on the country’s legacy leadership in pulp and paper production.

At the Sustainable Finishing of Textiles Conference, however, it was said that all of the environmental gains made by such sustainable new fibers can potentially be cancelled out in the further processing they are subjected to – and especially in resource-intensive conventional dyeing, finishing and decoration.

TMAS members Baldwin Technology and Coloreel have both developed solutions to address this issue.

TexCoat G4
During the conference, Baldwin’s VP of Global Business Development Rick Stanford explained that his company’s TexCoat G4 non-contact spray technology significantly reduces water, chemistry and energy consumption in the finishing process. It consistently and uniformly sprays chemistry across a fabric surface and applies it only where needed, on one or both sides.

Instant coloring
Coloreel’s CEO Mattias Nordin outlined the benefits of his company’s technology which enables the high-quality and instant coloring of a textile thread on-demand and can be paired with any existing embroidery machine without modification. This enables unique effects like shades and gradient to be achieved in an embroidery for the first time.
