From the Sector

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

At this year’s Techtextil in Frankfurt/Main (June 21st to June 24th) Trützschler Nonwovens, Trützschler Card Clothing and Trützschler Man-Made Fibers present various new and proven solutions for the nonwoven, card clothing and man-made fiber sectors. Join us at booth D80 in hall 12.0!

Trützschler Nonwovens invites to talk sustainable fibers such as hemp or linen and out-of-the-box fibers such as nettle and pineapple fibers. Our solutions for manufacturing innovative nonwoven products include machinery and complete production lines for paper grade pulp, re-generated cellulose fibers, cotton and various other natural fibers.

What happens when sustainable meets digital? Trützschler Nonwovens and software partner Proptium introduce T-ONE, our new digital working environment for both fiber- and polymer-based nonwoven producers. T-ONE supports routine tasks such as quality control and recipe management but also enables systematic line monitoring and data collection for T-ONE’s line optimizations.

Trützschler Man-Made Fibers introduces the OPTIMA-based, versatile TEC-O40 and TEC-O80 systems for extruding and spinning industrial yarns (IDY). The modular OPTIMA platform is highly flexible and adaptable to manufacturing a broad spectrum of (semi-)industrial yarns from polyamide, polypropylene or polyester.

• Innovation begins with creativity
• A pioneer of the manmade fiber industry

When the manmade fiber age began a century ago, a German company was responsible for the pioneering work involved. Barmag, established in 1922, was one of the world’s first companies to construct machines for the large-scale production of synthetic staple fibers. To this day, the leading manufacturer of manmade fiber spinning systems and texturing machines in Remscheid – a brand under the aegis of the Swiss Oerlikon Group since 2007 – has shaped technological progress in this sector; in future, with ever more innovations focusing on sustainability and digitalization.

Barmer Maschinenfabrik Aktiengesellschaft (Barmag) is founded in Barmen, located in the Bergische Land region, on March 27, 1922. The German and Dutch founders enter unchartered technological territory, one created as the result of a groundbreaking invention: in 1884, French chemist Count Hilaire Bernigaud de Chardonnet used nitrocellulose to produce the first so-called artificial silk, later known as rayon. The following decades see rapid development focusing on the search for synthetic textile fibers and their manufacturing technologies. As one of the first machine factories, Barmag battles its way through the eventful early years of the manmade fiber industry, the ‘Roaring Twenties’ and the Great Depression – and suffers the extensive destruction of its factories at the end of World War Two. Rebuilding is successful. With the unstoppable success story of purely synthetic plastic fibers such as polyamide, the company flourishes from the 1950s through to the 1970s, establishing sites in all international, for the textile industry at the time important, industrial regions and garnering prestige across the globe in the process. In the ups and downs of expansion, global competition and crises, Barmag reaches the very pinnacle of the market and becomes the preferred technological development partner for the manmade fiber industries in China, India and Turkey. The company has been a high-impact brand under the umbrella of the Oerlikon Group since 2007.

On the wings of innovation
Today, Oerlikon Barmag is a leading supplier of manmade fiber filament spinning systems and part of the Manmade Fibers Solutions business unit of the Oerlikon Polymer Processing Solutions Division. And our aspirations have not diminished: “The striving towards innovation and technological leadership has been, is and will always be part of our DNA”, emphasizes Georg Stausberg, CEO of Oerlikon Polymer Processing Solutions. In the past, this has been observable in such trailblazing innovations as the revolutionary WINGS generation of winders for POY in 2007 and WINGS for FDY in 2012. Currently, the focus of new and further developments is very much on digitalization and sustainability. Here, Oerlikon Barmag has – as one of the world’s first systems manufacturers – been implementing fully-networked smart factories for globally-leading polyester manufacturers since the end of the last decade. Within this context, digital solutions and automation are also helping to provide greater climate and environmental compatibility. This sustainability commitment is not only evidenced by the e-save label introduced for all products back in 2004: Oerlikon is endeavoring to also make all its sites carbon-neutral by 2030 and to acquire its energy exclusively from renewable sources. An ambitious target, whose achievement could be helped by the Oerlikon Barmag anniversary, states Georg Stausberg: “Innovation begins with creativity. And remembering the past provides plenty of motivation and inspiration for the future.”

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 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.

Maruti Printing transformed its business as the first printer in India to adopt the latest LED-UV curing technology from AMS Spectral UV, a Baldwin Technology Company. The hybrid system, which includes traditional UV modules, has been in production for nearly two years and has significantly expanded the offset printer’s capabilities for its customers, including adding the ability to print on all types of plastic substrates.

Not only does Maruti have the distinction of being an LED-UV trailblazer in India, but it also is first in the market to upgrade a high-speed, high-performance Heidelberg Speed Master 72F+L six-color printer with coating tower—which prints up to 15,000 sheets per hour—with AMS Spectral UV’s high-power AMS XP9-I Series LED-UV and P3 Smart UV curing modules.

Established in 1986 and headquartered in Ahmedabad, Gujarat, Maruti serves customers throughout India, providing offset printing of scratch cards, banners, booklets, brochures, calendars, danglers, pamphlets, posters, stickers and envelopes.

In January 2020, Maruti took delivery of two AMS XP9-I Series LED-UV modules to cure colors in the interdecks. The modules are ideal for the highest-speed curing situations that require consistent peak intensity to the substrate, which is the case for Maruti’s offset printing standard of perfection with every cure.

To cure ink, as well as a growing variety of LED coatings, Baldwin’s AMS Spectral UV modules can be located after print units, or in the press delivery after the coater. When inks and coatings are cured with LED-UV, they become instantly dry via photopolymerization, allowing for printing on any substrate, including plastics and metallized stocks. Plus, work can be immediately finished and sent to the bindery once it comes off the press, without the need for heat, spray powder or drying time.

In addition, Maruti took delivery of two P3 Smart UV curing modules for installation at the end of the press to cure any type of UV coating and expand the company’s scope of coating compatibility to general UV coatings in order to offer its customers the widest range of UV printed choices in the Indian market.

The P3 Smart UV housings are completely liquid-cooled to ensure safe, consistent performance and increased uptime, and modules feature a universal design, so that any unit can fit any print unit location. P3 modules can be changed, inspected and cleaned quickly and easily, without tools, and lamps slide and lock into place smoothly and securely.

The durability of the equipment and its chipset was a critical deciding factor in India’s climate. The latest-generation power-and-control cabinets are dust- and moisture-resistant, allowing them to withstand extreme heat and humidity, as well as powder and airborne contaminants, making the equipment ideal for operation in stressful conditions anywhere in the world. AMS Spectral UV’s latest generation of LED chips, designed for the highest-intensity curing applications, enable the curing of LED inks and coatings at record-setting speeds. They are built with resilient components, and the semi-conductor components are sealed, which allows the chips to work in a variety of rugged environments. Additionally, integrated circuits incorporated into the design electronically protect the LEDs and the entire system.
