• Fabric finishing and sanforization systems installed in the US and Turkey to enhance productivity

ST. LOUIS - Baldwin Technology Company Inc. has successfully installed six new fabric finishing and sanforizing precision spray systems in the US and Turkey. Despite the COVID-19 pandemic, the installations were completed in just 60 days, thanks to close collaboration between onsite Baldwin textile team members, local agents and remote support from the company’s product and technology center in Sweden.
For textiles, non-wovens and technical textiles, Baldwin’s precision spray technology processes a wide range of low-viscosity water-based chemicals, such as softeners, anti-microbial agents, water repellents, oil  repellents, flame retardants and more.

These systems enable fabric producers to significantly reduce chemical and water consumption, while speeding up production times and eliminating production steps, including drying and bath changeovers when switching fabric colors. “Our customers are major manufacturers in fabric dying, finishing and remoistening, and we want to provide outstanding service and support—even in times like this,” said Rick Stanford, Business Development Leader at Baldwin and the commercial leader of the US installations. “Not only does our precision spray technology enhance productivity in their process, but there is also zero waste, which goes hand-in-hand with the increased sustainability focus in the textile industry.”

In North Carolina, two new TexCoat G4 precision spray systems are now in production with major international vertical manufacturers of outdoor living, performance fabrics and automotive fabrics. In Georgia, a major vertical manufacturer of workwear and protective fabrics installed a sanfor precision spray system, which has helped the customer obtain deeper penetration of moisture into fabrics treated with durable water repellents. In Turkey, three new TexCoat G4 systems were installed in Çorlu, northwest of Istanbul, for a large producer of knit fabrics, such as T-shirts. “In Turkey, the manufacturer purchased and installed one TexCoat G4 system before COVID-19, and the customer was so pleased with the results that, during the pandemic, three more were purchased,” said Simone Morellini, Sales Manager- EMEAR at Baldwin and the commercial leader of the Turkish installations. “The systems were manufactured and installed during the lockdown, and now, all four systems are up and running, and being used heavily on a daily basis.” “With the success we have seen, we plan to apply the same strategies for upcoming installations, including the next one in Honduras: strong local management and customer coordination, combined with  effective remote support during the installation,” said Stanford.

• Gorilla Protect is a new company formed in May this year to promote the Catus face mask – a major leap forward in the effectiveness of personal protection products that are available to consumers in the fight against Covid-19.
• Behind Catus and the new company is Nova Textil, the established fabric finishing company based in Grefrath, Germany, and now run by father and son team Rainer and Oliver Hurtz.

Single stenter

Rainer Hurtz founded Nova Textil with a single Monforts Montex stenter and just five employees in 1999 and has steered its constant development and growth over the past twenty years.

“Our initial focus was on the coating of mainly glass fibre fabrics, awnings and sun protection products for outdoor furnishings,” he said. “We had a great customer who was providing us with so many orders that by 2005 we took the decision to order a second Montex stenter, in a special configuration. This also allowed us to enter the market for blackout and digital printing fabrics. We’ve had a great ongoing relationship with Monforts from the beginning.”

A third Montex stenter line was installed at the company’s Grefrath plant in 2015, by which time the company had grown to 40 people and a major new market had opened up in the supply of fabrics for promotional materials at exhibitions and trade shows.

“We had a fantastic two years in 2018 and 2019 and everything was going great for the first three months of this year, but in April it all came crashing down,” said Oliver Hurtz. “Coronavirus put an end to trade shows in 2020, which had a very serious impact on our business.”

At the same time, however, the company was exploring the potential of a new biocidal product from one of its chemicals suppliers which has both antiviral and antimicrobial properties.

Filtration

“We had already been producing coated fabrics for hot gas filtration and realised that in combination with this new microporous coating we had the basis for a very effective single-layer face mask,” Rainer said. “Achieving this with a single layer product rather than the usual three has resulted in a significant advance in comfort for the wearer and because the mask is able to disinfect itself and helps regulate humidity, it can be worn a number of times without needing to be washed, for greater convenience. It only needs to be washed when it gets dirty and can also be washed up to twenty times without losing its properties, which has to be preferable to single-use disposables.”

Catus face masks are based on 100% woven cotton and the active ingredients in the finish are a reaction mass of titanium dioxide and silver chloride certified to ISO 20743 for their antibacterial effect, and to ISO 18184 for their antiviral effect.

They are proven to  eliminate over  99.99% of the human coronavirus 229 E, with the multiplication of microorganisms such as germs and bacteria prevented by the biostatic action of silver salts and viruses destroyed by oxygen-releasing substances and a mechanism that attacks their fatty envelope. The virus membrane loses its cholesterol content and the virus is inactivated.

Colours

Gorilla Protect next plans to make the masks available in four colours – black, Bordeaux, olive and grey – and is also working on colour branding and printing labels.

“It’s not possible to print on the surface of the mask after it has been coated, but its is possible for volume orders to be printed before the treatment,” Oliver Hurtz said.

“Face masks are going to become an established part of life in the West like they are in Asia and need to be as comfortable and convenient as possible for the wearer,” his father concluded. “With these things in mind, we believe Catus is a significant step forward.”

New blade edge and integrity sensors save operators time and money

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, has announced that the Xcut saw, its newest tissue saw, now includes innovative sensors that monitor saw blade condition. This new technology tracks the edge of the blade and monitors it for the earliest indications of a blade crash.

The blade edge sensor monitors the current diameter of the blade, and automatically adjusts functions like grinder depth and other blade wear compensations. This sensor also gathers data that can be used to study the blade wear rate. Using a blade diameter measurement, which is performed in real time, along with the number of cuts and grind parameters, the PLC can fit a regression function to this data to inform the operator of the estimated number of cuts remaining on the blade for a given product diameter. Understanding blade wear allows operators to more easily optimize the process and preplan for blade changes.

In addition, the Xcut saw features a fiber optic blade integrity sensor. A blade with a chip or portion of the edge missing will produce cuts with streaks or shreds that are unacceptable to most producers. The defect is usually detected only after a significant amount of product is cut and potentially passed on to the packaging operations. The material expense, lost production and time it takes to purge the product from the system are costly. During normal operation, the sensor is covered by the blade. If at any point the sensor becomes uncovered, it puts the saw into emergency stop mode. The sensor would only become uncovered if the blade crashes or breaks. The emergency stop prevents further damage to the saw caused by slinging blade fragments.

“The blade edge technologies, along with the many other innovations on the Xcut, make the saw easier to maintain and safer to operate,” said Jonathon Zahn, PCMC’s Lead Mechanical Engineer for the Xcut. “Ease of use and operator safety are always goals when developing new products at PCMC.”

Neumünster – Oerlikon Neumag has successfully commissioned three staple fiber bicomponent systems in China. With capacities of 50 tons per day each, the systems are being used to manufacture coresheath bicomponent fibers made from PP/PE or PET/PE at two long-standing Oerlikon Manmade Fibers customers. These fibers are used to make hygiene products.

Oerlikon Neumag staple fiber technology still in demand

Despite coronavirus-related restrictions, the three new systems were installed within three and five months, all without any problems. They have meanwhile been operating under stable production conditions with optimum fiber quality of the very highest standards for several weeks now.

Many years of experience in bi-component spinning

Oerlikon Neumag looks back on many years of experience in constructing bicomponent staple fiber systems. The first system for this fiber type was commissioned as far back as 1995. Oerlikon Neumag offers solutions for the most varied cross-sections, ranging from sheath/core’, ‘side-by-side’, ‘island in the sea’, ‘orange type’ as well as ‘trilobal’. The applications are diverse: from self-crimping fibers, bonding fibers, super-microfibers all the way through to hollow fibers.

The Oerlikon Neumag bicomponent technology is particularly characterized by the extremely robust spin packs that have no expensive wear parts, which considerably reduces the costs here. The reconditioning costs when cleaning the spin packs are kept to an absolute minimum. Add to this the separate temperature transfer option in the spinning beam for the two polymers. As a result, the quality and the viscosity of the polymers can be accurately adjusted in accordance with the respective process requirements.

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

• Technical Absorbents Limited (TAL) has developed a new grade of superabsorbent fibre (SAF) specifically for use within a new range of SAF nonwoven fabrics that are more resistant to shrinkage.

The new SAF was developed in response to the demand from the medical industry for a superabsorbent fabric suitable for use in advanced wound pad dressings. The fibre had to be capable of withstanding the moisture used in the EtO sterilization process that is frequently employed in the production of the pads, in order to ensure product safety and compliance.

EtO sterilization is a low-temperature process (typically between 37 and 63°C) that uses ethylene oxide gas to reduce the level of infectious agents. While generally applied in gas form, however, the EtO is usually mixed with other substances – and often steam.

“Obviously superabsorbents and moisture generally aren’t a good combination at this stage in processing and can cause problems,” says TAL Product Development Director Dr Mark Paterson. “Other methods can be used, but when silicone materials are included, which is more frequently becoming the case, EtO is the preferred treatment method. Regular SAF grades tend to shrink a little and can become hard, which is often not desirable. This innovative SAF grade significantly reduces such potential problems.”

The amount of shrinkage caused by EtO sterilization depends very much on the product design and construction, he adds, but in general, the new SAF has been tested and proven to reduce fabric shrinkage by around 70%. It is suitable for use in all SAF nonwoven formats, whether needlepunched, thermally bonded or airlaid.

While the proprietary process developed at TAL for the production of this new fibre and resulting fabrics was prompted by the specific requirements of wound pad dressings, TAL sees opportunities for its application in other areas as well.

“It’s an extremely flexible fibre that can be easily switched with existing SAF grades when manufacturing fabrics and we have a number of current projects in which we’re exploring other end-uses,” Mark concludes. “We believe this new range could also open up entirely new application areas on the market.”

• 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”.
