From the Sector

Reifenhäuser Cast Sheet Coating - specialists for cast film, sheet extrusion and extrusion coating lines - will showcase a new production process for cost-effective film/nonwoven composites with an exceptionally low grammage at ICE (International Converting Exhibition) Europe. The leading international trade show for paper, film, and foil conversion and processing will be held at Messe München (Munich trade fair center) from March 15-17, 2022.

The Covid-19 pandemic and current supply shortages have exposed the dependence of companies on global supply chains. This situation is both a warning signal and an opportunity to boost and reorganize the local production of semi-finished products from the ground up. Reifenhäuser Cast Sheet Coating has now developed a trend-setting production process termed Ultrathin Coating, in particular for the sector of medical protective clothing. The process will permit customers to produce particularly lightweight film/nonwoven composites with greater cost efficiency and, as a result, more competitively. The patent-pending process has several advantages: It cuts film grammage by 66%; material consumption in the overall composite is reduced by 28%; and it slashes costs by up to 34% compared to conventional semi-finished products. Significant cost savings are achieved in various ways, for example, by replacing hotmelt adhesives, which reduces line maintenance to a great extent at the same time.

Mark Borutta, Sales & Marketing Specialist bei Reifenhäuser Cast Sheet Coating, erklärt: „Wir erleben derzeit einen nachhaltig wachsenden Mehrbedarf für medizinische Schutzbekleidung verbunden mit einer Rückholstrategie für lokale Produktionskapazitäten. Vor diesem Hintergrund erzielen Produzenten mit ‚Ultrathin Coating‘ einen schnellen Return on Invest und hohe Profitabilität – auch bei einer Produktion innerhalb Europas.“ Die Vlies-erfahrene Schwesterfirma Reifenhäuser Reicofil –führender Hersteller von Vliesstoffanlagen – hat die Entwicklung unterstützt.

Mark Borutta, Sales & Marketing specialist at Reifenhäuser Cast Sheet Coating, explains: "We are currently experiencing a sustained increase in demand for medical protective clothing combined with a return strategy for local production capacity. Against this backdrop, producers achieve a fast return on investment and high profitability with Ultrathin Coating - even when production is based in Europe." The sister company, Reifenhäuser Reicofil, an experienced and global leading manufacturer of nonwoven lines, provided their support to the development.

Even if manufacturers already produce medical protective clothing and prefer to handle the coating process internally in the future instead of importing the necessary composites, it is worthwhile to set up an in-house production facility. In either case, the investment in Ultrathin Coating usually pays for itself in less than 12 months. The lower material input also reduces the consumption of fossil raw materials and this in turn responds to the increased demand for more sustainable products.

• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

Hexcel announces its latest HexPly® XF surface technology that reduces shell manufacturing time within the wind blade surface finishing process. HexPly XF increases overall blade manufacturing efficiency by reducing time in the mold by up to two hours and by banishing surface defects that require rework before painting.

Hexcel’s HexPly XF surface technology has been formulated to address the limitations of current blade shell surfacing techniques whereby pinholes and other surface defects have to be repaired by hand to achieve the perfectly smooth surface required for painting.

HexPly XF surface technology introduces a new material format as the surface finishing layer, eliminating the need for a traditional in-mold gel coating process. HexPly® XF for infused rotor blades, is a lightweight non-woven semi-preg construction, comprising an epoxy resin matrix, that co-cures with standard epoxy infusion systems. The product has a successful track record in prepreg blades and has now been adapted for infusion processes.

Easy to handle and supplied in a ready to use roll form, HexPly XF can be quickly applied by hand or with semi-automated layup equipment. It features one self-adhesive, surface finishing side - indicated by a removable protective foil. This side of the prepreg is placed against a release agent treated mold surface. Once the material has been positioned, the lay-up of the blade shell structure can start immediately, and the laminate can be infused. After curing, the blade is de-molded with the manufacturer benefitting from a pinhole-free surface that needs minimal preparation before painting.

HexPly XF material is less than half the weight of a typical gel coat per square meter, reducing the overall weight of the blade. Additionally, the consistent areal weight and thickness of the prepreg film provide a completely uniform surface coating, ensuring blade weight distribution and balance are maintained, which is critical as rotor diameters continue to increase. With no need to handle or mix liquid chemicals as in the gel coat process, HexPly® XF also improves the health and safety working conditions on the shop floor.

The material has a shelf life of six weeks at ambient temperature, which also minimizes cold storage requirements and helps to reduce scrap.

• Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, today announced that, for the first time, Dyneema® Composite Fabrics are used by Moncler in the Fall/Winter 2020 Grenoble collection, which fuses form and function into high performance skiwear.

Moncler Grenoble is born of a passion for research and implements cutting-edge technology to push the limits of its potential. The design team identified Dyneema® as an innovative fabric it could use to push the level of its performance to the next peak, incorporating the material into the new collection as a departure from the conventional use of cotton and polyester.

Sandro Mandrino, the Head of Design for Moncler Grenoble, was the first designer of the luxury fashion brand to incorporate Dyneema® into one of his creations through the Moncler Genius project. The Moncler Genius project advocates radical co-creation where multiple designers create their own signature collections in collaboration with the house. Together, these collections translate into one vision of the future and, as one of the nine designers, Mandrino’s interpretation of the future of fashion features Dyneema® Composite Fabric.

Using variations of the fabric in both white and black allowed Mandrino to bring his vision to life by merging skiwear, space suits and technology all in one. “ 3 Moncler Grenoble is first and foremost about performance,” states Mandrino, who integrated constructive solutions with fabric technology to develop a line that was meant to perform both on and off the ski slopes.

Dyneema®, the world’s strongest and lightest fiber, is 15 times stronger than steel yet light enough to float on water. The unmatched performance and protection of products made with Dyneema® have made it the material of choice in critical applications where failure is not an option for more than 30 years. In fabric form, Dyneema® is available in composites, denim, knits, wovens and hybrids for composite reinforcements. And because Dyneema® fabrics are made using Dyneema® fiber, they intrinsically provide high strength, low weight, waterproof and breathable properties – allowing designers to fuse the technical performance of ultra-light products with aesthetic design that doesn’t sacrifice strength or durability.

The Moncler team used the Grenoble collection as an opportunity to experiment and further understand the nature and behavior of Dyneema® fabrics, while simultaneously incorporating material performance with practical design. “Future collections will focus on expanding to new designs and fabric options in collaboration with DSM,” adds Mandrino.

“We are very excited to be working with the Moncler team to launch a collection of wonderful garments that allow people to explore the outdoors more safely and for longer periods of time,” states Marcio Manique, Global Business Director, Consumer & Professional Protection, DSM Protective Materials. “We look forward to further supporting Moncler as they develop innovative, high-tech garments that are also sustainably sourced through the introduction of bio-based Dyneema® fabrics.”

In line with DSM’s commitment to protect people and the environment they live in, the world’s first-ever bio-based ultra-high molecular weight polyethylene fiber was introduced in May 2020. Bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE. DSM and Moncler’s continued partnership will not only provide high performance, light weight garments for outdoor enthusiasts but also environmentally sustainable alternatives that contribute to a more circular economy.

• 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.
