• Si-Quat by AFFIX Labs is a versatile anti-viral surface treatment that has been scientifically proven to last for months on any surface or textile while effectively killing the COVID-19 pathogen upon contact.
   

Helsinki - Leading chemical binding expert AFFIX Labs has harnessed its global experience in disease prevention to create the first long-lasting surface treatment proven to kill COVID-19. Si-Quat combines a safe and well-established disinfectant and a proprietary chemical binding technique, so that the active ingredient can kill viruses, including SARS-COV-2. Testing at Portugal’s Biochemistry Institute at the University of Lisbon proves that Si-Quat effectively kills the COVID-19 pathogens that it comes into contact with.

“Tragedies have unfolded across the globe, affecting different countries at varying degrees. The second waves of COVID-19 are just appearing on the horizon. This long-lasting surface treatment is a viable, accessible solution across cultures. By killing the COVID-19 pathogen on surfaces before it can infect people, the Si-Quat solution is a game changer. It can provide increased security and peace of mind to your communities, as well as your customers,” says Tom Sam, CEO of AFFIX Labs.

Si-Quat has been tested to kill 99.99% of microbes within minutes, while still being fully safe to touch. Proven to be effective for about a month on frequently touched surfaces, it is the longest lasting anti-viral surface treatment available to reduce the spread of the novel coronavirus. The product is non-corrosive, free from silver salts and heavy metal nanoparticles, and perfectly safe to touch.

Several major agencies around the globe have already accepted quaternary ammonium, the main ingredient in the surface coating, to be an effective surface treatment against the novel coronavirus, including the World Health Organization (WHO), the US Environmental Protection Agency, the American Chemistry Council (ACC) and the European Chemical Agency (ECHA).

Si-Quat was invented in January 2020 by the AFFIX Labs’ Repeltec development team to specifically help combat the COVID-19 outbreak. The product is based on the trusted and safe disinfectant quaternary ammonium, which is chemically bound to align silane quaternary ammonium molecules (silane quats) in a highly effective manner. Positively charged nitrogen particles then actively attract viruses and bacteria, penetrating the membranes and killing them within minutes.

Rigorous testing has shown Si-Quat to adhere to almost any surface, performing as the most durable surface treatment commercially available. Due to its incredibly strong layer, the solution only wears down on surfaces after thousands of touches or multiple cleaning cycles. This means that on heavily used surfaces, such as door handles and counters, Si-Quat will be effective for about a month. On rarely touched surfaces like walls, it has the potential to protect for years. Since the product is incredibly easy to apply, technicians require minimal training and only basic protection. They simply have to brush or spray Si-Quat onto the surface and allow it to dry for 6 hours.

“Other sanitising solutions require reapplication to every surface several times daily, interrupting business operations. This results in additional costs and disruptions at a time when many companies are already struggling,” Sam explains. “By combining proven efficacy, safety and long durability, Si-Quat is emerging as an important weapon in the battle against the spread of COVID-19.”

AFFIX Labs has begun to roll out the distribution of Si-Quat across the globe, with new regions being serviced every week. It is currently looking for distribution partners in local markets.

The project leading to the development of Si-Quat included funding from the European Institute of Innovation and Technology, a body of the European Union, under the Horizon 2020 Framework for Research and Innovation.

• Schleswig-Holstein Minister President visits Neumünster, Germany

Since the outbreak of the coronavirus pandemic, the worldwide demand for protective masks and apparel has resulted in a record number of new orders in the high double-digit millions of euros at the Oerlikon Nonwoven business unit of the Swiss Oerlikon Group. From the manufacturing site in Neumünster, Germany, the high-tech meltblown systems – with their patented ecuTE+ nonwovens electro-charging technology – are meanwhile be exported all over the world. For the very first time, a contract has now been signed with a business in Australia. Today, Schleswig-Holstein’s Minister President Daniel Günther was won over on site by the technology of a ‘global player’. Rainer Straub, Head of Oerlikon Nonwoven, was thrilled, stating: “The machines and systems for manufacturing manmade fiber and nonwovens solutions from Neumünster enjoy an outstanding reputation throughout the world. It is especially in this crisis that the technology from Schleswig-Holstein has proven itself to be absolutely world-class.”

In addition to a tour of the meltblown system and its assembly and production facilities, the visit by Minister President Daniel Günther had one purpose above all: the dialog between politicians and business. Rainer Straub, Head of Oerlikon Nonwoven, and Matthias Pilz, Head of Oerlikon Neumag, jointly expressed their thanks for the support that Oerlikon has repeatedly had the fortune to experience over the past months and years in Schleswig-Holstein and looked to the future full of hope. “As a result of our additional investment at the site here in Neumünster – be this in our new technology center that will be completed by the end of this year or in our new logistics center that is already operating – we, as one of the region’s largest employers, are continuing to move forward, supported by a State Government that is also focusing on both promoting industry and business and on advancing an efficient training and educational system, as innovation is only possible with outstanding engineers”, stated Matthias Pilz. And Rainer Straub directed his appeal specifically at the Minister President: “Treat education and training as a priority. Ultimately, they will secure the future of Schleswig-Holstein as a center of excellence and manufacturing!”

Five-million-euro digitalization program

Daniel Günther, the incumbent Minister President of Schleswig-Holstein since 2017, immediately responded, making reference to one of the Federal State’s current training initiatives: “The State Government is supporting higher education institutions and students in the present coronavirus crisis. With a five-million-euro digitalization program, we are investing on the long-term digitalization of our higher education institutions. With this, we are overall creating a future for young people, particularly also for those who could very well go on to invent the next generation of manmade fiber systems.” And the Minister President was just as impressed by the willingness and readiness with which Oerlikon has been providing high-level support since the beginning of the COVID-19 pandemic to master the present challenges as he was with the company’s meltblown technology itself. Rainer Straub explained: “When, at the beginning of the pandemic in February, demand for protective face masks increased rapidly, we at Oerlikon Nonwoven responded immediately. We ramped up all the available production capacities here in Neumünster in order to quickly manufacture nonwovens for producing face masks using our laboratory systems. As a result, we have been able to make a small, regional contribution to covering demand. In parallel, we have pulled out all the stops in order to systematically further expand our skills as machine and system builders so as to cater to the initially expected, and now also continuing, global demand for meltblown systems as quickly as possible.”

Leading meltblown technology

The Oerlikon Nonwoven meltblown technology – with which nonwovens for protective masks can also be manufactured, among other things – is recognized by the market as being the technically most efficient method for producing highly-separating filter media made from plastic fibers. The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems. “Ever more manufacturers in the most diverse countries are hoping to become independent of imports. Therefore, what we are experiencing in Germany is also happening in both industrialized and emerging countries throughout the world”, commented Rainer Straub. In addition to China, Turkey, the United Kingdom, South Korea, Austria and numerous countries in both North and South America, Australia and not least Germany will for the first time also be among the countries to which Oerlikon Nonwoven will be delivering machines and equipment before the end of 2021.

• Specialised in dye-sublimation printing, the Italian company has conquered the heights of the high fashion sector with its top-quality printed fabrics.
• With its recent investment in a direct-to-fabric printing line, Digitak is preparing to expand its range of printed products, focusing on fabric differentiation.

Dye sublimation printing of high fashion designs is the beating heart of Digitak, an Italian company specialised in digital textile printing. Operating in the textile district of Lombardy, Italy, the company has established itself among the main suppliers in the world of high fashion and sportswear in just under 15 years.

Making production versatility one of the cornerstones of its philosophy, Digitak has continued to invest in technology, as well as research and development its product portfolio. This forward-thinking approach has enabled the company to guarantee innovative, personalised products with meticulous attention to detail, with the highest – almost obsessive – standards of quality and maximum design flexibility. Over the years, the extensive experience gained by the company’s management in the field of sublimation with traditional and digital techniques, combined with their investment decisions have allowed Digitak to enhance its production performance, gradually implementing higher quality standards and differentiating itself from the competition in the complex and competitive sector of high fashion. An important feat, which has not, however, dampened its enthusiasm and willingness to continue growing and exceeding its goals. The company’s latest investment in a direct-to-fabric digital printing line with pigment ink propels the company into a new and promising production dimension.

Sublimation printing specialists

Since Digitak’s establishment, Filippo Taccani, the founder and current owner of the company, had set himself a clear and ambitious objective: “I wanted to take up the challenge of operating digitally - printing fabrics using this innovative technology to create products on a par with those  I had achieved with traditional sublimation textile printing methods during my previous work experience.”

The purchase of a Mimaki JV4 plotter, one of the first to be installed in Italy, marked the beginning of Digitak’s adventure. “To start the business, I needed a printing system that could operate with dispersed inks to print on polyester and I found the JV4 to be the best option,” explains Taccani. “It was an excellent decision, because I used these plotters to build the company and its success.”

The first Mimaki plotter was in fact followed by a second and a third. When it bought the fifth, the company moved to an industrial unit in Tradate (Varese) – Digitak’s current site – which now houses around fifteen Mimaki JV33 plotters, in addition to three Mimaki TS500-1800 wide-format sublimation printers, and a Mimaki TS300P-1800 high-speed sublimation printer. This Mimaki powered production facility – which is one of the company’s core strengths – was recently expanded with the addition of a Mimaki TX300P-1800B belt-type hybrid printing system, together with a Mimaki TR300-1850C textile coater and a Mimaki Tiger-1800.

“Naturally, over the years, we have also tested printing systems from other suppliers, but we have always returned to Mimaki. With high fashion as our key market, we need to guarantee our customers the highest levels of quality and, to date, we have never found solutions that beat the quality of this Japanese brand’s technology.”

According to Taccani, the difference lies in the “calligraphy” of Mimaki’s machines, that is the line of the ink on the fabric: “Unlike its competitors, Mimaki has focused on the ‘waveforms’, i.e. the electronics associated with the print heads. This attention paid to the way the ink jet is managed from the print head has allowed Mimaki to achieve unparalleled levels of accuracy, an aspect that has given my company a clear competitive edge.”

Moreover, at Digitak, quality comes before quantity: “We prefer to dedicate an extra day to production to guarantee the customer a final product that fully meets requirements and expectations. Mimaki’s technology not only suits this business model bult on top quality, but it crucially enables it.”

Operational and creative flexibility

Digitak currently prints around 2,000 linear metres of fabric per day. Its portfolio ranges from clothing and scarves, to beach and swimwear, with related personalised accessories, to sportswear, with technical properties such as breathability, comfort, resistance to external agents. The company have even added customised outdoor furniture to their offering of diverse and creative products.
The company’s machines operate continuously, 24/7. During the day, the machines are mainly used to develop and produce samples and colour proofs, while the actual production is carried out at night. “Thanks to our technology, we have developed an extraordinary operational flexibility. The fact that we have so many plotters allows us to work on multiple designs at the same time and to launch projects that are also very different from one another,” explains Taccani. “There are also some other crucial factors that have contributed, and continue to contribute, to increasing our production efficiency. The reliability of Mimaki’s solutions and the remote monitoring option offered is key. Once the standard start-up monitoring has been carried out and the machines are found to be printing correctly, we can let them work overnight without an operator. This is a great benefit for people who, like us, manage such a large and diverse fleet of machines.”

Digitak takes the same approach to customer service. Faced with an increasingly demanding market in terms of creativity, precision and completeness of service, the company wants to guarantee flexibility and customisation. “We decided to set up a department dedicated to the pre-press stage, in charge of preparing and checking the files supplied by customers. Seldom do our teams not need to do some editing of the files supplied, even if it’s only to make small changes that are essential for the print document to be as suitable as possible and to achieve the best final result.”

Technologies of the future

With a view to further enhancing production and customer service, Taccani has chosen to take on a new challenge, switching things up with some of the most recent investments.

While maintaining the focus on dye sublimation printing, Taccani has focused on technological diversification by installing a direct-to-fabric digital printing line. This consists of a Mimaki TX300P-1800B printing system with pigment inks and a TR300-1850C coater from Mimaki’s TR series. “The market continues to evolve and now requires even more flexibility regarding both processes and the fabrics supplied. This means that great opportunities exist for a print shop capable of simultaneously producing the same design – with minimal colour adjustment – on different fabrics, guaranteeing similar and accurate results. And this is precisely the path we are taking,” says Taccani. “Why have we opted for Mimaki again? Well, I had an opportunity to try out their new pigment inks and I immediately realised that they are a generation ahead of the other pigments available on the market. The cyan is very clean, the black is deep and there is a very interesting fullness of colour, suitable not only for furnishings, but also for other applications in the clothing sector.”

With its pigment inks, the new direct-to-fabric printing line allows Digitak to explore other related market segments. Thanks to the innovative automatic belt system, the TX300P-1800B guarantees good productivity and high-quality results. A standard of quality that is also boosted by the TR300-1850C fabric pre-treatment system: “This coater is essential for ensuring the best possible preparation of fabrics for printing. In fact, we are able to treat fabrics to make them suitable for the type of print they are intended for, sanitise them for specific applications and, in some cases, even dye them, with excellent quality.”

According to Taccani, another beneficial factor of direct-to-fabric pigment printing technology is the eco-sustainability of the process and its lower environmental impact. “We are proud to be able to offer our customers excellent printing results using little water and printing in ‘green mode’, with both the technologies we have available. I consider them winning technologies for the future, as both dye sublimation printing and direct-to-fabric printing with pigment inks use little water while mainly requiring the use of energy. Therefore, if you use renewable energy, then you’re done.”

Digitak’s other trump card is the Tiger-1800 installed in 2019. With this industrial printing system, the company aims to increase production volumes while maintaining its high-quality standards and further optimising costs. “We are excited to have these promising technologies available to us in-house. We are currently experimenting with these solutions, testing new opportunities and evaluating which paths to take to stay ahead of the game,” concludes Taccani.

• RUDOLF GROUP is thrilled to unveil the perfected antiviral features embedded in RUCO®-BAC AGP, the Company’s flagship antimicrobial product for textile applications.

As a consequence of COVID-19 global pandemic the demand for chemical auxiliaries with antimicrobial effect has boomed. RUDOLF GROUP invested important resources in the meticulous assessment of a new antiviral feature which is now added to one of their leading technologies .

Such an effort returned the surprisingly fast and most comprehensive antibacterial and antiviral textile finishing on the market: RUCO®-BAC AGP.

History has led to great vision and innovation

The powerful antimicrobial effectiveness of RUCO®-BAC AGP is rooted in the extraordinary properties of silver, whose antimicrobial magic is lost in the mists of time. Already known by the ancient Romans, Greeks and Egyptians, water and milk were preserved by using silver coins through the early modern age.

R&D at RUDOLF GROUP has mounted silver on highly sophisticated, functional and registered microstructures that strengthen and amplify the qualities of this noble metal.

RUDOLF’s proprietary microstructures are the responsible hidden secret and key technical breakthrough behind both efficacy and durability of RUCO®-BAC AGP. This innovation is now the preferred solution to help reducing proliferation and cross-contamination of bacteria and enveloped-virus on textiles.

One gram of microstructures has the astonishing superficial area of about 60 m². The advantage of a much higher surface is that the consumption of resources and dosages can be minimized by the factor 100 and that makes RUCO®-BAC AGP a highly conscious choice.

“Due to the microstructures, a virtually infinite protective shield is created in the textile from which highly effective positive silver ions are set free in small, exactly dosed quantities” says Dr. Dirk Sielemann, R&D Director at Rudolf Group.

Taking performance to the next level

RUCO-BAC AGP effectively protects any textile against bacteria (harmful and odour-causing) and its superior antiviral performance on textiles has been independently demonstrated by applying the most modern testing methods. Assessments were carried out on enveloped Coronaviridae families known to cause a broad spectrum of animal and human diseases.

The microstructures in RUCO®-BAC AGP trigger their powerful antibacterial and antiviral effects based on 3 distinctive inhibiting mechanisms:
1.    Blocking of oxygen-transporting enzymes therefore leading to impaired growth;
2.    Crushing of disulfide bonds and therefore structure of sulphur-containing proteins.
3.    Possible interference with Bacteria and virus surface protein in the membrane.

RUCO®-BAC AGP is intended for the protection of the treated textiles and the microstructures of RUCO®-BAC AGP were studied thinking of performance and safety. It is suitable for next-to-skin applications and cytotoxicity tests show that RUCO®-BAC AGP has no influence on the natural microflora of the skin. Furthermore, because of the adhesion mechanism of its microstructures, RUCO®-BAC AGP is only active in/on the textile and it is non-migrating. 

“This year 202o is being highly emotional and it’s leading to the widespread introduction of antimicrobials on textile and to a myriad of vague, misleading or unsubstantiated marketing claims”, states Dr. Gunther Duschek, Managing Director at RUDOLF GROUP. He concludes “As a highly responsible company, we move cautiously and stand for technologies and practices that are effective, truthful and limit the exposure of apparel manufacturers, retailers and buyers to any risk”.

Shanghai – Sateri has unveiled FinexTM as its new product brand for recycled fibre. FinexTM, short for ‘Fibre Next’, is an innovative next-generation cellulosic fibre containing recycled content. Internationally known outdoor brand Lafuma has produced FinexTM apparel ahead of 618, China’s major mid-year online shopping festival, while independent China designer Rico Lee will launch his FinexTM apparel next month.

Since its announcement in March this year of a breakthrough in commercial production of viscose using recycled textile waste, Sateri has worked closely with its downstream yarn and garment manufacturing partners to bring the recycled fibre product to the consumer market.

“We’re pleased to collaborate with Sateri as one of their first brand partners for FinexTM. Sateri’s dedication to this partnership made it possible for Lafuma to produce T-shirts with this fine quality fibre in a short time. T-shirts made with FinexTM will be among the offerings Lafuma has in store for the 618 festival as we look to support environmentally-friendly and excellent performance solutions to strengthen our position as a leading outdoor apparel brand,” said Wu Qian, General Manager of Lafuma China.

Echoing similar sentiments is Rico Lee who established his own independent label in 2014, “I jumped at the opportunity to collaborate with Sateri when they approached me because FinexTM encapsulates what my brand stands for – Beautiful Technology that combines function and fashion.”

Tom Liu, Sateri’s Commercial Vice President said, “Like our flagship brand EcoCosy®, FinexTM is made from bio-based natural fibres. Innovation and technology has made cellulosic textile fibre recycling possible and FinexTM represents how nature not only renews itself but that products made from nature can also be regenerated. This, at its heart, is what circular fashion looks like. Our brand promise to customers remains constant– Sateri’s products are sustainable, high quality, efficient, and cost-effective. The FinexTM tagline ‘Together For A Better Next’ expresses our aspiration to be the partner of choice for next-generation fibre - we thank Lafuma and Rico Lee for pioneering with us on this quest.”

Last month, Sateri announced its entry into China’s Lyocell fibre market. The recent string of product portfolio expansion announcements is underpinned by Sateri’s business strategy to capture value. Allen Zhang, President of Sateri said, “Being the world’s largest viscose producer gives us the advantages that come with volume, but value is what we hope differentiates us. By this, we don’t only mean higher value products like Lyocell or FinexTM but also the value we bring to communities, country, climate and customers.”

Globally, less than 1% of material used to produce clothing is recycled into new clothing. This presents a big opportunity for textile fibre recycling, particularly in China which is the largest textile producing country in the world. Last month, Sateri became a council member of the China Association of Circular Economy (CACE). The company will work closely with CACE’s Textile Waste Comprehensive Utilisation Committee to establish standards and promote industrial-scale textile waste recycling. Sateri is part of the Singapore-based RGE group of companies which has committed USD200 million into next-generation textile fibre innovation and technology.

STAMFORD – German ultralight aircraft specialist Flight Design has chosen Hexcel as its key supplier adopting low-temperature curing prepreg into its aircraft production. Hexcel’s HexPly® M79 Carbon Fiber prepregs deliver a more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Design and then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype. As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70˚C for eight hours or 80˚C for four hours, reducing tooling costs and increasing build rates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective of laminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components. The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”

POY process now even more energy-efficient

Following several years of development with partner Siemens, Oerlikon Barmag kicked off serial production of its new drive unit for POY systems at the beginning of the year. The new component makes stands out above all with regards to energy efficiency.

The requirements-specific design of the compact inverter unit ensures functional optimization of the winder’s control functions. And the new component is used in conjunction with a performance-optimized chuck motor. This means that energy savings of up to 3% can be achieved for the take-up.

Further customer benefits include a significant reduction in cables and cable trays. The reduced number of switching cabinets also saves space. Following intensive field tests at two well-known customers last year, the compact inverter unit was finally released for serial manufacture at the beginning of 2020.
There are plans to deliver several thousand positions with the new component this year.

a leading Asian large-scale manufacturer of manmade fibers and polymers has invested in a new Oerlikon Nonwoven meltblown system. The recently-signed contract comprises a 2-beam system for manufacturing filtration nonwovens – predominantly for medical products such as face masks – with a nominal capacity of up to 1,200 tons of nonwovens a year. The commercial production launch has been scheduled for the fourth quarter of 2020.

The 2-beam system has an operating width of 1.6 meters and is equipped with the new patented Oerlikon Nonwoven electro-charging unit. The Oerlikon Nonwoven meltblown technology is recognized by the market as being the technically most efficient method for producing highly-separating filter media made from manmade fibers, particularly in conjunction with electrostatic charging and with extremely low-pressure loss. Electro-charging the filter nonwovens allows the manufacture of sophisticated EPA- and HEPA-class filter media as well as media that comply with the requirements of N95-, FFP2- and FFP3-class respiratory masks.

The demand for filtration nonwovens for medical applications has risen tremendously across the globe since the outbreak of the Sars-CoV-2 (coronavirus) epidemic, presenting all manufacturers with huge challenges. A meltblown system will be commissioning at the site of a leading Western European nonwovens producers as early as the second quarter of 2020. This system will be deployed exclusively in the manufacture of nonwovens for respiratory masks.

Due to the current state of emergency with regards to the local supply of face masks, Oerlikon Nonwoven is currently using its own laboratory system to produce electrostatically-charged filter media which are being sent to local small businesses and companies for the manufacture of face masks. 

Major technological changes to Oerlikon Neumag’s RoTac³ tangling unit produce even more efficient BCF yarn tangling. On the one hand, the tangling nozzle has been flow - optimized, allowing the air pressure to be lowered by approximately 10 percent compared to its predecessor while maintaining the same knot strength. Furthermore, the nozzle bearing arrangements have been improved. Consequently, either higher speeds or nozzle rings with greater numbers of holes can be used, generating more knots in the yarn.

Even at high production speeds, tangling knots can be set considerably more evenly with the RoTac³ than in the case of other conventional tangling units. Frequent tangling dropouts are now a thing of the past. This ensures better yarn quality and has a positive impact on further processing. The result: the carpet has a visibly more even appearance.

Stable and efficient yarn production is hugely important to yarn manufacturers. Not only does the evenness of the tangling knots make the investment interesting, so too does the energy efficiency of the RoTac³. The tangling unit requires up to 50 percent less energy for generating compressed air. Against the background of rising energy prices, this represents an excellent prerequisite for optimizing production costs.

Oerlikon Neumag has been able to secure various retrofit contracts since the launch of the RoTac³ in 2015. And new systems are predominantly equipped with RoTac³. The RoTac³ is included in the standard scope of delivery for the newer BCF S8 system. The tangling unit is available as an option both for the single-end Sytec One system and the three - end S+ and it can also be retrofitted on request.
