From the Sector

With the PFAFF 4520, engineers and technicians from PFAFF have designed a full-automatic production line (CE compliant) for processing multi-layer disposable masks, which meets the requirements of "German engineering" in a unique way. The product combines 150 years of expertise in joining textile materials and a concentrated know-how of the PFAFF INDUSTRIAL and KSL brands in the areas of process control, automation and robotics.

The PFAFF 4520 is an investment in a robust and sophisticated production line (MADE IN GERMANY) with an exceptionally reliable working process. In times of Covid-19 it is so important to rely on the right equipment for the mask production and avoid costly readjustments or an unnecessary second investment!

Key facts of the unit:

-    Size of the mask: 175 x 95 mm
-    Output:  3,500 – 4,000 masks per hour
-    1-, 2- or 3 ply processing  (Non-woven/filtration fabric)
-    SPS (PLC) control of the entire mask system
-    Exceedingly quiet working process of the whole unit
-    Ultrasonic welding components from German manufacturers
-    Protective housing for occupational safety of the operator
-    Packing station + printing station for personalized masks (on request)

The machine package also includes important features in the pre- and after sales:

PFAFF technicians ensure the adjustment of the desired customer material (non-woven or similar filter material) and the number of layers (1-, 2-, 3-ply) to the machine and make a "Ready to production" installation of the whole unit at the customer.  A fast service response time in after-sales (by involvement of the PFAFF sales- and service partner on site) ensures a maximum production output.

On Thursday, September 24, the Lenzing Group, a leading manufacturer of wood-based cellulose specialty fibers, and Hof University opened a new Nonwoven Development Center (VEZ). As a strategic partner, Lenzing has access to a state-of-the-art development line at the campus in Münchberg with immediate effect. This offers new opportunities for sustainable fiber and nonwoven innovations for a wide range of applications including hygiene, body care and medical.

In line with the sCore TEN corporate strategy, the Lenzing Group is focusing on sustainable innovations, which are agreed in an optimum manner to the needs of the value chain. „We offer our customers and partners a decisive competitive advantage: agility. The pilot plant in the VEZ allows the resource-efficient development of fiber and nonwoven innovations on a small scale”, Jürgen Eizinger, Vice President Business Unit Nonwovens at Lenzing, explains.

The VEZ was completed according to schedule in September 2020, after Lenzing and the University of Hof signed a cooperation agreement for its use in 2019. The timing is perfect. Developments at political level, such as the directive (EU) 2019/904 of the European Parliament and of the Council of 5 June 2019 on the reduction of the impact of certain plastic products on the environment, increase demand for responsibly manufactured nonwovens. The so-called Single-Use Plastics Directive aims at building awareness and greater transparency with regard to wet wipes and feminine hygiene products.

With its VEOCEL™ branded wood-based cellulose fibers, Lenzing has been laying the foundation for many years for sustainable nonwoven applications and will test and develop innovative ideas using the new possibilities offered by the VEZ. „We are noticing increasing interest in sustainable concepts from biodegradable cellulose fibers“, Jürgen Eizinger sums up the market development of the last months and adds: „We are aware that the fibers used have an enormous influence on the final product. For this reason our commitment goes beyond fiber production.“

With the spunlace pilot plant at the VEZ, Lenzing will support customers and partners more intensively in the development of new nonwoven applications and at the same time promote cooperation in the field of marketing. In the previous year, the company already established new certification standards for the VEOCEL™ brand. Since then certified manufacturers can only use the VEOCEL™ logo with blends of biodegradable cellulose fibers. With this measure, the VEOCEL™ brand allows consumers to make a more conscious product selection.

With its #ItsInOurHands environmental initiative, the VEOCEL™ brand also actively contributes to creating awareness. More detailed information can be obtained on itsinourhands.com.

• 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.”

• 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.”

• Protective masks, everyday masks, disinfecting wipes and surgical gowns are goods in demand in times of corona.
• In their manufacture, textile machines are at the beginning of the production chain.

The production of the textile raw material is the first step of the usually multi-stage production processes. Members of the VDMA Textile Machinery Association are at the beginning of this technological chain.

The production of protective masks starts with the manufacture of the filter material, which for surgical masks as well as FFP2 and FFP3 respirator masks consists of fine-pored nonwoven fabric to intercept coronaviruses. In addition to the systems, machines and components used for this purpose, measurement and control technology ensures the highest quality of important parameters such as basis weight and air permeability. Nonwovens used for respiratory masks have to meet the same high-quality requirements as the masks – to ensure the protection of the mask wearer.

Members of the VDMA Textile Machinery Association have reacted to the new market requirements in a very short time and developed new technologies for knitted, warp knitted as well as woven mouth and nose masks that can be produced without the need for sewing. For surgical masks, FFP2 respirators and social distancing masks, a wide variety of other materials and combinations of materials are used (nonwovens, woven fabrics, knitted or warp knitted fabrics and laminates thereof). Elastic bands are required to wear the masks and several association members provide technologies for their production.

Materials for masks can be treated with textile chemicals to make them antiviral and antibacterial. For this purpose, the VDMA member companies offer application systems which apply the corresponding chemicals to fabric webs. As already mentioned, quality assurance is extremely important for medical products. For this purpose, member companies of the VDMA offer software systems with which each mask can be traced through the entire production process.

VDMA members also offer solutions for the assembly of respirator masks, some of which were developed at short notice. These solutions enable respirators to be produced that meet the relevant standards and the highest quality requirements of customers and market surveillance. This applies to systems for the production of surgical masks and FFP respirators. At the end of the production chain, machines are used to pack masks in single or multiple packs.

In pandemic times, the demand for protective gowns (so-called surgical gowns) also increases. The same applies to disinfecting wipes. For these textile products, too, VDMA members manufacture tailor-made machines for production through to packaging. The quality of the products is ensured by means of measurement and control technology.

In the wake of the corona crisis, VDMA Textile Machinery has launched a new series of web events called "Textile Machinery Webtalk". Here, experts from up to four VDMA member companies present their innovative technologies on a specific topic in a maximum of 90 minutes and are available to answer questions from participants. The presentations are held in English. Participation in the web events is free of charge.
Topics of the first two webtalks were:
"Technologies for the production of melt-blown nonwovens for respiratory protection masks (FFP masks and surgical masks)."
"Technologies for the production of respiratory protection masks (FFP masks and surgical masks)."

The format is well received. Around 180 people from more than 30 countries took part in the first two webtalks. With this format, the VDMA reaches both textile and nonwovens manufacturers who already manufacture these products and companies that want to invest in new business areas.

The next webtalk will take place on 23 July 2020 from 14.00 to 16.00 (CEST) on the current topic "Technology solutions to produce fully-fashioned community face masks." Experts from KARL MAYER, STOLL by KARL MAYER and Jakob Müller will be presenting their technologies for producing everyday textile masks to an international expert audience.

• 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.

• Australian production of medical masks to commence from April 2021 with Oerlikon Nonwoven meltblown technology

Neumünster/Germany, Brisbane/Queensland/Australia – Queensland company OZ Health Plus will establish Australia’s first manufacturing plant to make the critical fine plastic material used in most protective face masks. OZ Health Plus has purchased a plant of the Swiss-based technology company Oerlikon to establish a Queensland-based production plant for spun-bond and meltblown nonwovens. These fabrics are essential for Australia’s face mask manufac-turers, who currently produce about 500 million medical and industrial masks per year. However the fabrics have to be imported from overseas and access to these materials has been severely disrupted during the COVID-19 pandemic.

Oerlikon’s German-based business unit Oerlikon Nonwoven has now executed legal and commercial arrangements to supply the specialised machinery which can manufacture the nonwoven material lo-cally. The same machinery is used to make almost all face masks material manufactured in Europe. The world-leading Oerlikon Nonwoven meltblown plant will commence operations in April next year, with a second stage planned for late 2021.

The Oerlikon Nonwoven plant can produce meltblown fabrics for 500 million masks per year, along with other medical and non-medical grade products, filtration products, sanitary items, antiseptic wipes and more. Rainer Straub, Head of Oerlikon Nonwoven said: “We are very proud that we can now for the first time supply our Oerlikon Nonwoven meltblown technology to Australia. Due to the short delivery time, we hope to make our contribution to the Australian population and their safe sup-ply of high-quality protective masks as soon as possible.”

Queensland company secures manufacturing plant for the only Australian production of critical face mask material

OZ Health Plus director Darren Fooks said: “Australia has access to raw polypropylene feedstock but lacks the plant to convert that raw material to specialised spunbond and meltblown fabrics. These fabrics are essential for local mask manufacturing. The Australian-based Oerlikon Nonwoven plant will fill the production chain gap for Australia by producing the fabrics we need for mask production and many other products – it will reduce Australia’s protective mask supply chain from thousands of kilo-metres, to tens of kilometres.”

“Our decision in favor of Oerlikon Nonwoven was a given once we had analyzed the material samples. It was a matter of course for us that the Business Unit of the Oerlikon Manmade Fibers segment could supply high-quality machines and systems”, added Darren Fooks.

OZ Health Plus’ new facilities will take up 15,000 m2 of manufacturing space and will employ 100 full-time roles once the second stage of the project is complete. OZ Health Plus continues to work with both Queensland and Federal Government stakeholders and values their support in bringing this vital capability to Queensland.

Leading meltblown technology

Oerlikon Nonwoven meltblown technology, which can also be used to produce nonwovens for protec-tive masks, is recognized in the market as the technically most efficient method of producing high-separation filter media from plastic fibers. Most of the protective mask capacities available in Europe to date are produced on Oerlikon Nonwoven equipment.

• Digital processes also speed up the manufacture of meltblown systems

in order to further optimize the material provision for the Oerlikon Neumag and Oerlikon Nonwoven business units and to strengthen internal processes at the German site in Neumünster, the Manmade Fibers segment of the Swiss Oerlikon Group decided last year to invest in a state-of-the-art logistics center with a new lift center. It has already been fully operational for a few weeks. This is tremendously helpful for speeding up the processing of the numerous orders for meltblown systems for manufacturing high-quality nonwovens for protective masks and apparel that Oerlikon Nonwoven has received over the past months alone

Investing in a new Oerlikon Neumag and Oerlikon Nonwoven logistics center is paying dividends: the processing speed when manufacturing new systems – very much to the benefit of customers – considerably improved in the first week after the center started operating, not least as a result of the optimized processes and the material handling. After 25 years, the time had finally come to break new ground and to better equip ourselves for the future requirements of the markets. The paternoster storage facility to date not only needed to have regular repairs carried out due to its age, it was also too small for the projects increasingly being carried out today. The only 90 m² were capable of storing around 12,000 parts. In contrast, the new logistics center now offers more than 250 m² of storage space for in excess of 25,000 parts. As a result, this now also houses all small parts, which used to be stored in the high-rack facility due to lack of space.

New hardware, new software
Coinciding with the opening of the new logistics center, Oerlikon also introduced new digital processes that will also help cope with the increasing production volumes. To this end, consistently maintained master data and photos for all parts ensure safe, paper-free storage and handling of the material from now on. In order to minimize mistakes, a laser pointer now indicates from which or to which space the goods are moved. Furthermore, a photo of the material, sorted to type, is displayed on the screen. The digitalization of the warehousing facilities secures the pick and put-away process so that checking material numbers becomes superfluous when removing items from the warehouse.

• Producing fabric for medical gowns: Advanced barrier effect solutions support COVID-19 efforts

Huntsman Textile Effects and Bao Minh Textile, one of the largest and most modern woven fabric producers in Vietnam, are collaborating to produce fabric that meets the stringent performance standards required of isolation gowns. High-quality medical gowns are essential protective wear for healthcare workers combatting the global COVID-19 pandemic, but these are in short supply worldwide.

Bao Minh Textile will initially treat 760,000 meters of woven fabric with a carefully curated combination of Huntsman Textile Effects barrier effect solutions and auxiliaries. This fabric is sufficient to produce 345,000 high-grade isolation gowns.

Bao Minh Textile’s isolation gown fabric relies on a range of Huntsman pretreatment, dyeing and finishing solutions. These include CLARITE® ONE, an all-in-one pretreatment for peroxide bleaching; NOVACRON® and TERASIL® dyes; PHOBOL® CP-C, an excellent oil-, water- and stain-repellent finish; and PHOBOTEX® RSY, a non-fluorinated durable water repellent with extremely high washing resistance. PHOBOL® EXTENDER XAN is also applied to further increase wash durability.
