• Composite textiles for modern mobility
• Extremely lightweight, high tensile components by vombaur

In the snow, on a plane, in an electric vehicle or on a bicycle: no matter where and how we are on the road – composite textiles by vombaur ensure that we make good progress. With materials that are both extremely light and extremely reliable.

Lightweight components for modern mobility
Modern mobility relies on high-tech lightweight components Narrow textiles by vombaur are woven from high-performance fibres. On looms that are specially made for particularly demanding composite textiles: the textile company uses special machines to produce high-tech woven tapes with closed selvedges and elasticated UD tubulars that retain their 0° orientation over the entire length of the component – regardless of the diameter. Since they do not exhibit undesired break points caused by seams or welding, they not only have a particularly high bursting strength, they are also extremely reliable and durable.

Challenging applications
"From snowboards to aerospace – the applications for our composite textiles are demanding; the mechanical, chemical and thermal requirements are extreme," explains COO Christoph Schliefer. "As a development partner, we at vombaur are therefore often involved in product development at an early stage. We specify our woven tapes and tubulars individually for each project to suit the specific task at hand."

High quality raw materials, wide variety of geometries
The variety of shapes is virtually unlimited. vombaur manufactures 3D fabrics for composites in individual special shapes from carbon, aramid, glass or hybrids. Curves, edges, tubulars, spiral fabrics – the shape of the 3D fabrics, like the material itself, depends entirely on the task at hand. Powder or non-woven coatings create additional important properties.

Pioneering tech tex
"Developments in the field of modern mobility are happening at a rapid pace," emphasizes Schliefer. "With our composite textiles for extremely lightweight and high tenacity components, we at vombaur are also pushing these developments forward."

Technical textiles fulfil many functions: they hold, they lift, they fixate, they stretch – and they tension. In this function narrow textiles fulfil an important task in product development. And they offer significant advantages over metal or plastic tensioning devices such as springs, clamps or cable ties.

Properties
Textiles are light: a property that plays a central role in modern mobility. Textiles are flexible: from extremely high to extremely low elasticity: the force-elongation behaviour of elasticated narrow textiles can be precisely defined. Depending on the tensioning task to be performed. Textiles tension in tight packaging spaces: elastics can also be used where space is too tight for springs and clasps. Textiles are energy efficient: lightweight, with high tensioning force. Textiles are easy to handle: replace a connector spontaneously and without tools, quickly change the length or roll up and store a supply. And textiles are sustainable: natural fibres and rubber are natural and ecologically degradable raw materials; synthetic fibres can be completely produced from recycled materials.

Applications
Development teams in numerous industries leverage these properties for their products. For example, for flexible machine parts in mechanical engineering, for switch contacts in electrical engineering, for oscillation-capable locking systems in the construction industry, for noise- and vibration-free seating systems in the automotive sector or for grip rings in the toys industry.

Tasks
Particularly en vogue today, when we are spending more time than usual in our own homes: applications for narrow textiles in the furniture industry. They go far beyond the area of legacy home textiles: as tensioning elements in armchairs, sofas and chairs, as hinge solutions in cupboards, as fixation elements in extendable or folding tables. Narrow textiles are used for gripping tasks almost everywhere in the living room.

"JUMBO-Textil specialises in precisely implementing the individual requirements for defined force-elongation values of elasticated narrow textiles: we adapt the technical properties of our products precisely to the specific task and the respective raw materials," explains Werner Thiex, Sales Director Automotive. "Precise technical specification plus sustainable raw materials – this is a crucial combination in the 21st century".

• 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.”

• Kettelhack GmbH – a German leader in the dyeing and finishing of monochrome fabrics for high-quality and durable workwear and bed linen – has this year retired its existing Monforts sanforizing line after 35 years of daily service, replacing it with a new one.

The first line was installed in 1985 during a decisive time for the company.

Taking the helm in the early 1980s, Jan Kettelhack – the current CEO, owner and great grandson of Heinrich Kettelhack who founded the company back in 1874 – made a number of decisions that have secured its success over the following decades.

In 1982 Kettelhack had to vacate its existing plant in the city of Rheine due to urban development restrictions and despite a general sense of crisis in the European textile industry at that time, opted to relocate and build a new highly automated plant that was not reliant on mechanical and personnel-intensive processes. This was aligned with a greater focus on competitive international sales.

From 1986, the company’s proficiency as a specialist in solid-colour textiles led to workwear textiles becoming a bedrock of the business. Continuous investments in machinery and technical equipment have resulted in a fully integrated and rationalised single source site dedicated solely to what the company does best – the expert dyeing and finishing of textiles.

Crucial process steps

These stages in the textile value-added chain, Jan Kettelhack has observed, are crucial to the quality of a final product in workwear – whether it stands the test in everyday use, how comfortable it is, and how many washes it can withstand.

Central to this is the sanforizing process, which pre-shrinks a fabric by compressing it prior to washing. This limits any residual or further shrinkage in a made-up finished garment to less than 1%, to ensure perfect comfort and fit over an extended lifetime.

“We certainly can’t complain about the performance of the old Monfortex sanforizing line which gave us so many uninterrupted years of service, but certain spare parts for it were becoming increasingly hard to source, the control unit was becoming a little unstable and we couldn’t risk potential interruptions to our production schedule,” says Kettelhack plant manager Hendrik Pleimann. “In many ways, the new Monfortex sanforizer is much the same as the old one in terms of its mechanical reliability and robust construction, but of course today’s drives are much more efficient, and when it comes to the automation features and control units – and the data we can generate and analyse for increasing efficiency – that’s a whole new world.”

Qualitex 800

The two-metres-wide Monfortex line benefits from the latest Qualitex 800 control system which allows all parameters to be easily automated via the 24-inch colour touchscreen, including production speed, control of all fabric feed devices, rotation spray or steaming cylinder options, the width of the stretching field and the rubber belt pressure.

The integrated Compactomat system allows a continuous indication and control of the shrinkage values and the temperatures of the shrinking cylinder and felt calender. Up to 10,000 separate process parameter records can be generated and stored by the data manager.

Full line management can be optimised via the batch-specific calculation of all process material consumption and water and electricity use, with any standstill times analysed and immediately corrected for the future.

Any further assistance required is available via Monforts Teleservice, with direct connection to technicians and virtual access to machine analysis.

Professional

Commissioning of the new Monfortex line at Kettelhack commenced in January and it was fully operational in a relatively short time.

“This was a very professional installation provided by the Monforts team with whom we have a very good relationship dating back many years, and everyone knew what was required from both sides,” says Mr Pleimann. “Our operators have found the new line very user friendly and we are very pleased with how everything proceeded so smoothly. An unexpected benefit is that the new line is also a lot quieter, of course, which is something our operatives are appreciating.”

Key features of the Monfortex line are the proven fabric preparation, weft straightening and spreading units, prior to the compressive shrinkage machine with a 750mm shrinking cylinder, and a felt calender equipped with 2,000mm diameter drying cylinder. The line also features an integrated automatic grinding unit.

Customer service

Kettelhack is processing primarily cotton and polyester woven fabrics, with lyocell becoming increasingly popular in workwear for its softness and comfort.

As part of its customer service, the company stocks more than a million metres of grey fabric and at least 1.2 million metres of finished and rolled standard fabric in its warehouse at any one time, with a further 750,000 metres permanently in production.

While a significant cost, this commitment ensures Kettelhack customers can be fully flexible and rely on it as a partner.

“As a family-run company with around a hundred employees, Kettelhack operates very differently to bigger businesses which have to constantly consider their immediate quarterly profits,” Mr Pleimann concludes. “The thinking at Kettelhack is in terms of the next twenty years and ensuring that the business will be just as successful for the next generation as it is today. We also have a very flat organisational structure in which everyone is involved and takes an active part, which makes it a very nice place to work.”

• 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.

• 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”.

• Antiviral properties of Sanitized® products on synthetics validated

Tests conducted by independent laboratories have now confirmed that a treatment with Sanitized® T 99-19 and Sanitized® T 11-15 reduces the viral load on PES textiles by
up to 99 %.

Swiss company SANITIZED AG announces the validation from impartial labs that Sanitized®T 99-19 and Sanitized®T 11-15 are also effective against viruses (in accordance with ISO 18184:2019). Tests were performed using a feline coronavirus with structures and mechanisms reminiscent of SARS-Cov2. Patented technology featuring an ammonium silicate compound  is employed in Sanitized®T 99-19 and Sanitized®T 11-15 utilizes tried and tested silver technology.

These additives are the perfect tool for an antiviral and antibacterial treatment of face masks, protective professional medical clothing, bed linens, or mattresses. The formulation of both products remains completely untouched, thus ensuring that it will continue to offer outstanding protection against bacteria.

Before a final product’s antiviral properties can be publicly promoted, viral tests must be performed in specialized laboratories. Compliance with local legal regulations is essential here. SANITIZED AG explicitly points out that this is standard procedure and has composed a preliminary Guide for Treating PPE (personal protective equipment) with biocide products.
