From the Sector

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 Oerlikon Nonwoven. The meltblown technology from Neumünster is recognized by the market as being one of the technically most efficient methods for producing highly-separating filter media made from plastic fibers.

Protective equipment demands high-end nonwoven products
The rising demand for protective masks and other medical protective equipment since the start of the coronavirus pandemic and the associated global ramping up of production capacities has also resulted in an increase in the demand for nonwovens for the production thereof. Initially, this resulted in bottlenecks in the provision of meltblown filter nonwovens. To this end, there had until this point be very few producers of medical filter nonwovens outside China. Meanwhile, the demand for spunbond systems is also rising. “Due to the structure of our group, we are in the fortunate position to swiftly reallocate and free up our production capacities. This means that we are able to relatively quickly deliver not only meltblown systems, but also spunbond equipment”, explains Dr. Ingo Mählmann, Head of Sales & Marketing at Oerlikon Nonwoven, talking about the positive situation at the company.

The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems. “Our machines and systems for manufacturing manmade fiber and nonwovens solutions enjoy an outstanding reputation throughout the world. Ever more manufacturers in the most diverse countries are hoping to become independent of imports”, comments Dr. Mählmann. The Oerlikon Nonwoven meltblown systems are being delivered to Germany, China, Turkey, United Kingdom, South Korea, Italy, France, North America and – for the very first time – to Australia until well into 2021.

Quality and efficiency in demand
Depending on the purpose of the application, medical PPE (personal protection equipment) should be breathable and comfortable to wear, protect medical staff against viruses, bacteria and other harmful substances and form a barrier against liquids. For these reasons, they are often made of either pure spunbond or of spunbond-meltblown combinations. Here, the meltblown nonwoven core assumes the barrier or filter task, while the spunbond has to retain its shape, while being tear-resistant, abrasion-proof, absorbent, particularly flame-resistant and nevertheless extremely soft on the skin.

All masks are not created equal – thanks to the ecuTEC+
Protection against infections such as coronavirus can only be guaranteed with the right quality.

The nonwovens can be electrostatically-charged in order to further improve the filter performance without additionally increasing breathing resistance. Here, Oerlikon Nonwovenʼs patented ecuTEC+ electro-charging unit excels in terms of its extreme flexibility. Nonwovens manufacturers can freely choose between numerous variation options and set the optimal charging method and intensity for their specific applications. In this way, even the smallest particles are still attracted and reliable separated by a relatively open-pored nonwoven. Nevertheless, mask wearers are still able to easily breathe in and out due to the comparatively loose formation of the fibers. To this end, it comes as no surprise that all meltblown systems currently destined for the production of mask nonwovens are equipped with the ecuTEC+ unit.

With immediate effect, the first fabric mask with the official “TESTEX Community Mask” test label is available from the two Swiss textile firms, Schoeller Textil AG and Forster Rohner AG. Since May, the companies have been able to offer their masks with official EMPA recommendation. The sustainable and economical quality products consist primarily of recycled performance fabric which can be recycled once again at the end of its service life.

Swiss cooperation
With the product from the two companies based in the east of Switzerland, Schoeller Textil AG and Forster Rohner AG, the Swiss market now boasts the first textile mask featuring the label “TESTEX Community Mask”. Together with the EMPA, TESTEX has developed a testing procedure which analyses textile masks with regard to their filter function, spray resistance, comfort of wear, reusability and additionally skin-friendliness of the textiles. By now, numerous Swiss and international consumers, as well as the employees of major companies (e.g. transport companies) have satisfied themselves of the suitability of the Swiss Community Masks for everyday use.

Recyclable fabric made with 60 % recycled fibres
The high-quality fabric components in the mask were developed by the innovative Rheintal-based company Schoeller Textil AG. The two-layer polyester fabric is hydrophilic (having an affinity to water) on the outside and hydrophobic (water-repelling) on the outside and furthermore features an antibacterial finish. Thanks to the cotton-like feel, the fabric offers pleasant wearing comfort. The sustainable fabric consists of 60 % recycled fibres. Within the framework of the wear2wear recycling cooperation (www.wear2wear.org), the masks can be recycled once again when they reach the end of their life cycle.

The reusable mask is made up by Forster Rohner AG in St. Gallen and in its European subsidiaries. It impresses with optimum fit and tested skin tolerance. All components of
the mask comply with the OEKO-TEX® Standard 100. The testing process screens for numerous controlled and non-controlled substances. Masks with the OEKO-TEX® Standard 100 label are safe to wear. Forster Rohner also added a fashion component to the technicallyinnovative mask. The subsidiary, Jakob Schlaepfer AG, created a special print for the mask of the kind otherwise only developed for famous couture and prêt-à-porter fashion labels around the world. In addition to white and plain-coloured masks, a limited edition of available print designs emerges, or specific colours or even individual print designs are created for major customers.

• 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. Interested parties can register here.

• 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.

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. 

For the sixth time now, Oerlikon Nonwoven will be showcasing market- and customer-oriented solutions for hygiene, medical, filtration and other technical applications at the globally-leading nonwovens trade fair INDEX in Geneva, Switzerland. Between March 31 and April 3, 2020, visitors to the trade fair can convince themselves of the Neumünsterbased systems constructor’s extensive product and process know-how.

Comprehensive spunbond portfolio – always the right solution
Oerlikon Nonwoven meanwhile has a very broad range of spunbond technology products and services. The process for manufacturing geotextiles from polyester or polypropylene has been optimized; it is characterized by high production capacities and yields, with simultaneously low energy consumption for producing benchmark nonwoven products.

For the manufacture of hygiene nonwovens, Oerlikon Nonwoven offers its new QSR (Quality Sized Right) systems. Here, the benefits of the Chinese machine construction partner’s nonwoven formation are integrated into the complete solution. The advantage for nonwovens producers: highly competitive solutions at attractive prices with comparably low investment.

Cost-efficiently manufacturing meltblown nonwovens
New, unique and highly sophisticated filter media can be easily and efficiently manufactured thanks to Oerlikon Nonwoven’s optimized meltblown technology. Whether as a stand-alone system with one or several positions, as ‘plug & produce’ installations for already existing systems or in conjunction with other technologies: the Oerlikon Nonwoven meltblown process already enables the cost-efficient manufacture of meltblown nonwovens with the quality requirements of tomorrow. Ever more producers are choosing the meanwhile extensively tried-and-tested and consistently further-developed Oerlikon Nonwoven meltblown solutions.

Airlaid technology for the nonwovens of tomorrow
Pulp or cellulose fibers as raw material for manufacturing nonwovens are currently virtually unrivaled with regards to sustainability and environmental compatibility. The Oerlikon Nonwoven airlaid process is the ideal solution for processing this raw material into high-end products for a wide range of applications. Today, there is huge demand for manufacturing solutions for high-quality, lightweight airlaid nonwovens with economically attractive production speeds and system throughputs. In this area, the patented Oerlikon Nonwoven formation process – which also permits the homogeneous mixing of the most diverse raw materials, while simultaneously guaranteeing superb evenness and homogeneous fiber laying – is setting standards even for nonwovens with low running meter weights. And the benefits of this technology are also increasingly gaining significance in sustainable recycling applications.

P&G patented PHANTOM technology from Teknoweb Materials
Also being showcased at the trade fair stand is the P&G patented PHANTOM technology from Teknoweb Materials, Oerlikon Nonwoven’s strategic partner for hygiene products and wipes. The PHANTOM technology is released to Teknoweb Materials by P&G in worldwide exclusive license. The PHANTOM technology is the superior dry laid alternative technology for manufacturing wet wipes from pulp and polymer fibers, for example. Compared to conventional, known processes, this technology offers superior performances with cost advantage in much more eco-friendly products. Dispensing with hydroentanglement renders subsequent drying of the material redundant. Targeted process management allows the optimal setting of the relevant product parameters such as softness, tenacity, dirt absorption and liquid absorption.

The Oerlikon Nonwoven experts will be presenting efficient solutions and comprehensive technology know-how for challenging filtration tasks to an international trade audience at the FiltXPO 2020 in Chicago, USA (Stand # 420), taking place between February 26 and 28.

Meltblown technology is one of the most efficient methods for producing very fine and highly-separating filter media made from manmade fibers. New, unique and highly-sophisticated filter media are easy to manufacture thanks to Oerlikon Nonwoven’s optimized meltblown technology. This process is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam, Furthermore, the novel guidance and distribution of the process air outside the coathanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures particularly homogeneous nonwoven properties and basis weights even in the case of delicate raw materials.

The Oerlikon Nonwoven charging unit stands out against other concepts currently available on the market. Users can freely choose from a large number of variation possibilities and set the optimum charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA- and HEPA-class filter media.

The new forming section ensures improved nonwoven formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixedfiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.

At FILTECH, eurolaser will demonstrate the advantages of a large-format laser system in the processing of filter material. The handling of the material from the roll is particularly comfortable with eurolaser's own conveyor system in combination with a feeding unit. At the FILTECH, eurolaser presents its L-3200 with a table size of 1,800 x 3,200 mm.

Large-format laser systems are ideal for cutting of filter material. The contactless process guarantees a constant cutting quality without tool wear. The table concept with extraction reduces dust and keeps the material in place at the same time. In addition, the thermal laser process ensures that when cutting synthetic textiles, the edges are sealed and thus protected from fraying. This makes subsequent processing much easier. The laser also allows fine details and filigree structures which cannot be produced by a knife.

Conveyor – for all materials from the roll
Especially for all materials from the roll, eurolaser offers several of its systems as conveyor versions. In these versions, the surface of the processing tables consists of a stainless steel rod mesh. They are equipped with an automatic unwinding unit as fabric feed. The unwinding speed adapts to the retraction of the conveyor and the decreasing roll diameter. For very large and heavy rolls there is also a driven unwinding unit. Integrated laser projection lines indicate the correct position so that the roll change is fast and error-free. The remaining length capture ensures that there is always enough material left on the roll for the respective job.

For even more flexibility, there is space for additional tools or marking modules next to the laser. The motion system comes from the Swiss world market leader for digital cutters ZÜND. The machines are equipped with the Laserscout software suite, which contains the right software packages tailored to the application.

At next month’s Techtextil 2019 in Frankfurt, Germany, A. Monforts Textilmaschinen GmbH & Co. KG will be highlighting all of the innovative features that have made the Montex stenter the undisputed leader in the field of technical fabric finishing.

“Techtextil is a very important show for us, because technical textiles are a key pillar of our production programme and many of our existing customers will be exhibiting or attending, as well as those we have yet to meet,” says Jürgen Hanel, Head of Technical Textiles at Monforts. “The show provides us with an opportunity to explain the diverse end-products that can be successfully finished on our stenters, as well as with our coating units.”

A number of successful recent Monforts Montex stenter installations in Europe, for example, are dedicated to the production of wide-width digital printing substrates, to high volume automotive fabrics and to heavy duty filter media, to name just three advanced technical materials.

Digital print
Three Montex stenters have just been installed at the plant of a leading finisher of substrates for digital printing substrates in Germany – two of them in extra-wide widths of 5.4 metres – for drying after both washing and coating processes.

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

“The substrates of choice for digital printing are 100% polyester warp knits which have extremely smooth surfaces,” says Hanel. “This is becoming increasingly critical due to the general move away from PVC coatings which were the standard in the past. Quality inspection and control systems analyse every square metre of fabric to ensure completely uniform and blemish-free production.”

The fabrics produced are resilient and allow excellent take-up of inks for 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 soft signage installers.
These fabrics are being supplied fully finished, in weights of between 50-350gsm and in rolls of up to 600kg or 1,800 metres.

As the countdown to the 2018 edition of Cinte Techtextil China enters its last two months, the final exhibitor line-up is starting to take shape.
