From the Sector

• 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.”

• Members of TMAS – the Swedish textile machinery association – have adopted a range of new strategies in response to the Covid-19 pandemic, aimed at assisting manufacturers of textiles and apparel to adjust to a new normal, as Europe and other regions emerge cautiously from lockdown.

“Many European companies have been forced into testing new working methods and looking at what it’s possible to do remotely, and how to exploit automation to the full, in order to become more flexible,” says TMAS Secretary General Therese Premler-Andersson. “Others have been taking risks where they see opportunies and there’s a new sense of solidarity among companies.

“It’s extremely encouraging, for example, that over five hundred European companies from across our supply chain are reported to have responded to the shortages of facemasks and PPE – protective personal equipment – by converting parts of their sites or investing in new equipment.”

New supply chains

Amongst them are TMAS members of the ACG Group, who quickly established a dedicated new nonwovens fabric converting and single-use garment making-up plant to supply to the Swedish health authorities. From a standing start in March, this is now producing 1.8 million square metres of converted fabric and turning it into 692,000 finished medical garments each month.

“In 2020 so far, we have seen new value chains being created and a certain amount of permanent reshoring is now inevitable,” says Premler-Andersson. “This is being backed by the new funding announced in the European Union’s Next Generation EU plan, with €750 billion marked for helping industry recover. As the European Commission President Ursula von der Leyen has stressed, “green and digital” transitions hold the key to Europe’s future prosperity and resilience, and TMAS members have new solutions to assist in both areas.”

Remote working

Automated solutions have opened up many possibilities for remote working during the pandemic. Texo AB, for example, the specialist in wide-width weaving looms for the paper industry, was able to successfully complete the build and delivery of a major multi-container order between April and May.

“Our new Remote Guidance software now makes it possible for us to carry out some of the commissioning and troubleshooting of such new lines remotely, which has been helpful” says Texo AB President Anders Svensson.

Svegea of Sweden, which has spent the past few months developing its new CR-210 fabric relaxation machine for knitted fabrics, has also successfully set up and installed a number of machines remotely, which the company has never attempted before.

“The pandemic has definitely led to some inventive solutions for us and with international travel currently not possible, we are finding better methods of digital communication and collaboration all the time,” says Svegea managing director Hakan Steene.

Eric Norling, Vice President of the Precision Application business of Baldwin Technology, believes the pandemic may have a more permanent impact on global travel.

“We have now proven that e-meetings and virtual collaboration tools are effective,” he says. “Baldwin implemented a home office work regime from April with only production personnel and R&D researchers at the workplace. These past few months have shown that we can be just as effective and do not need to travel for physical meetings to the same extent that was previously thought to be necessary.”

Pär Hedman, Sales and Marketing Manager for IRO AB, however, believes such advances can only go so far at the moment.

“Video conferences have taken a big leap forward, especially in development projects, and this method of communication is here to stay, but it will never completely replace personal meetings,” he says. “And textile fabrics need to be touched, examined and accepted by the senses, which is impossible to do via digital media today. The coming haptic internet, however, may well even change that too.”

Social distancing

The many garment factories now equipped with Eton Systems UPS work stations – designed to save considerable costs through automation – have meanwhile benefited from the unintentional social distancing they automatically provide compared to factories with conventional banks of sewing machines.

“These companies have been able to continue operating throughout the pandemic due to the spaced nature of our automated plant configurations,” says Eton Systems Business Development Manager Roger Ryrlén. “The UPS system has been established for some time, but planned spacing has proved an accidental plus for our customers – with improved productivity.”

“Innovations from TMAS member companies have been coming thick and fast recently due to their advanced know-how in automation concepts,” Premler-Andersson concludes.  “If anything, the restrictions imposed by the Covid-19 pandemic have only accelerated these initiatives by obliging our members to take new approaches.”

Shanghai - Sateri has signed the Fashion Industry Charter for Climate Action, becoming the first viscose producer in China to support this global fashion agenda. An initiative convened by the United Nations Framework Convention on Climate Change (UNFCCC), this charter calls on the fashion industry to support the goals of the Paris Agreement in limiting global temperature rise to well below two degrees Celsius above pre-industrial levels, by achieving 30 per cent aggregate reduction in greenhouse gas (GHG) emissions by 2030, including the supply chain.

Niclas Svenningsen, Manager of Global Climate Action, UNFCCC, said, “UNFCCC is excited to have Sateri joining the Fashion Industry Charter on Climate Action and committing towards global climate action as the first Chinese viscose producer to do so. We hope that it will inspire more textile companies from China to join and take action.”

As a signatory of the Charter, Sateri looks forward to participating in relevant Working Groups which bring together stakeholders and experts in the fashion and textile sectors. In recent months, Sateri has joined several other leading industry multi-stakeholder associations. These include the Sustainable Apparel Coalition (SAC), China Association of Circular Economy (CACE), and the European Disposables and Nonwovens Association (EDANA).

Allen Zhang, President of Sateri, said, “Sateri is committed to growing our business as sustainably as we can. Our adoption of the Fashion Charter goals is a bold leap but we believe that pushing the boundaries is necessary. We are also stepping up on our engagement with industry partners to be part of the collective action to accelerate efforts against climate change.  As we formulate Sateri Vision 2030 for a sustainable business, carbon reduction will be one of our key focus areas”.

In addition to stepping up greenhouse gas emission reductions in its own operations, the company will continue to support decarbonisation efforts of the downstream textile value chain. Late last year, in collaboration with the China National Textile and Apparel Council (CNTAC), a Climate Leadership Whitepaper was published. The paper analysed how innovation in Sateri’s EcoCosy® fibre products help reduce carbon emission during yarn and fabric manufacturing stages, and also proposed next steps in achieving industry-wide emission reduction goals.   

Sateri attained an ‘A-‘ score in CDP (formerly Carbon Disclosure Project) for Climate Change in 2019;  a score which is higher than the ‘C’ average globally, in Asia, as well as in the Textiles and Fabric Goods sector. 

• 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.

Materials for in excess of one million protective masks
Within the context of supporting the critical infrastructure in Germany, Oerlikon Nonwoven immediately began converting its laboratory systems in Neumünster to manufacture nonwovens at the end of March. With this, only small local businesses and companies were initially supported in the manufacture of oronasal masks.
With the laboratory system at the R&D Center material for more than one million protective masks a month can be manufactured.

The laboratory has meanwhile run out of raw materials and new orders for replacement materials had to be placed before Easter – with current delivery times of approx. 3 weeks. This will allow production to be resumed, and even considerably expanded, in May.
The laboratory system is now once again being deployed to produce nonwovens that will be used to make more than million face masks / oronasal masks a month. “We will not be manufacturing the masks ourselves. We have meanwhile found both corresponding partner companies and also private individuals demanding nonwovens”, adds Andreas Frisch, commenting on the developments.

Boom in orders
Furthermore, Oerlikon Nonwoven has also fired up the production of the machines and systems used for its meltblown technology. The demand from Germany, Europe and the rest of the world has quickly
secured the company a high in orders..
We will be commissioning the first meltblown system at the site of a leading Western European nonwovens producers in the second quarter of 2020. The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon
Nonwoven systems.

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.

Innovative Prozessbandkonstruktionen als sicherer Schutz gegen Elektrostatik und Anhaftungen

Zur größten globalen Vliesstoffmesse, der INDEX in Genf, unterstreicht die technische Weberei GKD – Gebr. Kufferath AG (GKD) einmal mehr ihre ganzheitliche Beratungs- und Engineering-Kompetenz für die Nonwovens-Industrie. Getreu der Unternehmensvision, nur solche Produkte und Lösungen zu schaffen, die die Welt gesünder, sicherer und sauberer machen, präsentiert GKD hier ein umfassendes Spektrum an Gewebe- und Spiralgliederbändern für die Vliesformierung, -trocknung und -verfestigung. Im Mittelpunkt des Messeauftritts stehen zwei wegweisende Entwicklungen: CONDUCTO® 7690 mit metallischen Multifilen und antihaftbeschichtete Glashybrid-Gewebebänder. Abgerundet wird der Messeauftritt durch maßgeschneiderte Filtermedien aus Metallgewebe, die in Zentralfiltern, Spinnbalken und Anblassieben der Polymerfiltration nachweislich neue Maßstäbe setzen. Zu allen Themen stehen die langjährig erfahrenen GKD-Experten bei der INDEX für vertiefende Gespräche zur Verfügung.

Maximale Prozesssicherheit und Anlagenverfügbarkeit entscheiden in der Vliesstoffindustrie über Wirtschaftlichkeit der Produktion und Produkterfolg. Eine zentrale Aufgabe übernehmen dabei Transport- und Prozessbänder von GKD durch anlagen- und produktspezifisch ausgelegte Gewebekonstruktionen und Werkstoffe.

Spunlaid-Vliesformierung: Metallische Ableitung auch für Hygieneprodukte
Mit CONDUCTO® 7690, einer Gewebekonstruktion aus Polyester-Monofilen und metallischen Multifilen, ist es GKD gelungen, Elektrostatik ableitendes Metall so aufzubereiten, dass es auch für anspruchsvolle Medizin- und Hygieneprodukte risikolos einsetzbar ist. Das jüngste Mitglied der CONDUCTO®-Familie ermöglicht eine bis zu zehn Mal höhere Ableitung elektrostatischer Aufladung als herkömmliche Bänder. Die webtechnisch auf der Bandrückseite eingebrachte Metallfaser hat keinen Kontakt zum Produkt. Das flexible Garn aus Edelstahlfasern korrodiert nicht, ist robust und biegewechselfreundlich. Zugleich optimiert es die Ableitung elektrostatischer Aufladung in bisher nicht gekanntem Maße. Diese Eigenschaften paart die neue Gewebekonstruktion mit den bekannten Vorteilen aller CONDUCTO®-Formierbänder: hoher Mitnahmeeffekt, homogene Vliesbildung, optimale Vliesabnahme und einfache Reinigung.

Vliesverfestigung und -trocknung: Jahrelange Laufzeit ohne Anhaftungen
Ein deutliches Plus an Prozesseffizienz kennzeichnet die Erfolgsbilanz der antihaftbeschichteten Glashybrid-Gewebebänder von GKD: Im mehrjährigen Praxiseinsatz als Ober- und Unterband haben sie in anspruchsvollen Thermobonding-Prozessen mit stark klebenden Produkten die hohen Erwartungen an Prozessperformance und Produktqualität weit übertroffen. Die einlagige Gewebekonstruktion aus Metalldrähten im Schuss und Glasfaserlitze als Kette macht die Bänder zu energieeffizienten Leichtgewichten. Jahrelange Laufzeit, minimierte Reinigungsintervalle und hohe Fertigungsgeschwindigkeit unterstreichen ihre Wirtschaftlichkeit. Auch bei großen Arbeitsbreiten oder starken Schrumpfkräften des Produktes überzeugen die Glashybrid-Gewebebänder durch exzellente Querstabilität und Laufeigenschaften. Ihre vollständige hochwertige PFA-Beschichtung schützt Drähte, Litzen und Kreuzungspunkte sogar bei stark klebenden Produkten oder dem Einsatz von BiCo-Fasern vor Anhaftungen aller Art. Glashybrid-Gewebebänder sind Temperaturbeständig bis 250 Grad Celsius und längen sich nicht.

Converting: Praxisbewährte und leistungsstarke Alternative
Kundenspezifisch angepasste Spiralgliederbänder aus eigener Fertigung ergänzen die bewährte Prozessband-Palette von GKD. Insbesondere bei sehr breiten oder schnelllaufenden Anlagen, auf denen Hygieneprodukte hergestellt werden, sind die Spiralgliederbänder oftmals eine attraktive Alternative. Mit hoher Luftdurchlässigkeit und Formstabilität unterstreichen sie einmal mehr die ganzheitliche Prozess- und Transportbandkompetenz von GKD.

Polymerfiltration: Lange Standzeiten, präzise Filtration
Im Zentralfilter verleihen prozessabhängig ausgelegte, mehrlagige Metallgewebesiebe von GKD den Siebwechslern lange Standzeiten. Die aus bis zu sechs Lagen Optimiertem Tressengewebe gefertigten Filterronden oder -kerzen überzeugen durch hohe Schmutzaufnahmekapazität, feine Abscheideraten und geringe Verblockungsneigung. Im Spinnbalken optimieren anwendungsindividuelle Medien in Langfiltern oder Ronden die Filtration des Schmelzflusses und verlängern gleichzeitig die Standzeiten der Spinndüsen. Anblassiebe aus Wabenträgerplatten, die beidseitig mit speziell veredelten Gewebekonstruktionen bestückt werden, gewährleisten durch eine homogenisierte Strömung gleichmäßigen Faserfluss.

Tailor-made solutions for hygiene, medical, filtration and other technical applications as well as extensive product and process know-how – with these arguments Oerlikon Nonwoven made a convincing appearance at the 18th Shanghai International Nonwoven Exhibition (SINCE) that took place from December 11 to 13.

Dr. Ingo Mählmann, Head of Sales and Marketing of Oerlikon Nonwoven, was very pleased with the three lively days at the trade fair: "The many discussions showed that we are on the right track with our strategy and the further development of our technologies with regard to nonwovens. Visitors were impressed by our technology solutions for disposable nonwoven fabrics or geotextiles". Almost all wellknown nonwoven fabric producers visited the trade fair stand of the plant manufacturer from Neumünster to find out about the advantages of spunbond, meltblown and airlaid technologies.

Overall, the nonwoven fabric team of the Oerlikon Group draws a very positive conclusion and looks back with satisfaction on the intensive and good quality discussions as well as numerous concrete inquiries from customers and prospective customers.

• Organic Waste Systems and TÜV confirm fiber biodegradability also in fresh water
• All white LENZING™ Viscose, Modal and Lyocell fibers are now certified for all environments
• Global legislators aim at limiting plastic waste persisting in the environment for centuries
• EU Single-Use Plastics Directive partly regulates usage of plastic products
• Biodegradable materials such as wood-based fibers are the best alternative to single-use plastics

The Lenzing Group received confirmation of the full biodegradability of its fibers in fresh water by the independent research laboratory Organic Waste Systems (OWS). The new and existing international certifications conducted by OWS and issued by TÜV Austria verify that LENZING™ Viscose fibers, LENZING™ Modal fibers and LENZING™ Lyocell fibers are biodegradable in all natural and industrial environments: in the soil, compost as well as in fresh and in marine water.

The biodegradability of cellulosic products and the synthetic fiber polyester was tested in fresh water at OWS according to valid international standards, e.g. ISO 14851. At the end of the trial period, LENZING™ wood-based cellulosic fibers, cotton and paper pulp were shown to be fully biodegradable in fresh water in contrast to synthetic polyester fibers. The fact that synthetic materials are not biodegradable leads to major problems in wastewater treatment plants and potentially marine litter. In turn, this not only harms fish and birds living in and close to the oceans but also all marine organisms and us humans.

“The Lenzing Group operates a truly circular business model based on the renewable raw material wood to produce biodegradable fibers returning to nature after use. This complete cycle comprises the starting point of the core value of sustainability embedded in our company strategy sCore TEN and is the ‘raison d’etre’ of our company”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group. “In living up to this positioning, we not only enhance the business of our suppliers, customers and partners along the value chain but also improve the state of the entire textile and nonwovens industries.”

Both the textile and nonwovens industries face huge challenges with respect to littering. If current trends continue, the oceans could contain more plastic than fish by 2050. Therefore, legislative bodies worldwide can no longer ignore the issue and have moved towards plastics legislation aimed at limiting the vast amount of waste. In response, European lawmakers issued the Single-Use Plastics Directive currently being transposed into national legislation in the EU member states.

Conventional wet wipes and hygiene products mostly contain plastic and were thus identified as one of the product categories to be singled out. Less polluting alternatives are generally encouraged by NGOs and legislators, e.g. products made of biodegradable wood-based cellulosic fibers. Plastic waste including microplastic can persist in the environment for centuries. In contrast, biodegradable materials are the best alternative to single-use plastics because they fully convert back to nature by definition and thus do not require recycling.
