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.”

• 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.

• New 20,000 ton Lyocell line commences production in Shandong

Sateri has successfully commenced production of Lyocell fibre in Rizhao, Shandong, China. In collaboration with Asia Symbol, China’s leading producer of pulp and packaging board, the newly installed 20,000 ton per annum production line will broaden Sateri’s portfolio of high quality fibre products, and bolster Lyocell supply to the textile and non-woven markets.

Industry associations such as the China National Textile and Apparel Council (CNTAC) welcome the news. Duan Xiaoping, Deputy President of CNTAC and President of the China Chemical Fibers Association (CCFA), said, “Lyocell is not only a higher value product but also an eco-friendly fibre that is bio-based and minimises chemical use and emissions. Sateri’s investment in Lyocell is very much aligned with the aim for technical and product upgrading for China’s textile industry.”

A natural and biodegradable fibre, Sateri’s Lyocell is made from wood pulp sourced from sustainable plantations. It is manufactured using closed-loop technology, requiring minimal chemical input during the production process, and utilising an organic solvent that can be almost fully recovered and recycled. Lyocell is used to produce high quality textiles and personal hygiene materials. Textiles made from Lyocell possess high tenacity and bright lustre, and share similar qualities with textiles made from viscose – soft and silky with good drape, breathability, and absorption.

Sateri is part of the RGE group of companies which has committed to investing USD200 million to advance next-generation textile fibre innovation and technology. In March this year, Sateri achieved a breakthrough in commercial production of viscose using recycled textile waste.

Parkdale Mills Collaborates with FDA, Gates Foundation and Others to Supply Swabs for Coronavirus Tests

Parkdale Mills subsidiary U.S. Cotton has joined in an effort with the Food & Drug Administration (FDA), the Gates Foundation, UnitedHealth Group and Quantigen to ramp up production of spun synthetic swabs to help the country’s frontline health care workers administering tests for the COVID-19 disease.

U.S. Cotton has developed a fully synthetic, polyester-based Q-tip-type swab that can be used in coronavirus diagnostic testing.  The U.S. Food and Drug Administration just announced that these synthetic swabs – with a design similar to Q-tips – could be used to test patients for the coronavirus.
U.S. Cotton, based in Cleveland, Ohio, plans to leverage its large-scale manufacturing capacity to rapidly increase production of large quantities of the polyester swabs, which are in short supply for testing kits across the country.

The FDA has determined that spun synthetic swabs can be used in COVID-19 testing based on the results from a clinical investigation stemming from its collaboration with UnitedHealth Group, the Gates Foundation and Quantigen.  

This is the second major COVID-19 relief project that Parkdale has helped. Earlier Parkdale constructed a supply chain that includes Hanes, Fruit of the Loom, and many other U.S. companies in the production of PPE masks needed by frontline medical staff treating the virus.

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

Swiss company SANITIZED AG celebrates validation from impartial labs that Sanitized®T 99-19 and Sanitized®T 11-15 are also effective against viruses (in accordance with ISO 18184:2019).
Tests were performed using a feline coronavirus with structures and mechanisms reminiscent of SARS-Cov2.

Patented technology featuring an ammonium silicate compound is employed in Sanitized®T 99-19 and Sanitized®T 11-15 utilizes tried and tested silver technology. These additives are the perfect tool for an antiviral and antibacterial treatment of face masks, protective professional medical clothing, bed linens, or mattresses.
The formulation of both products remains completely untouched, thus ensuring that it will continue to offer outstanding protection against bacteria.

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

SANITIZED AG has been supporting the work of hygienists in hospitals, doctor’s offices, nursing and care facilities for many years with its antimicrobial - and now also antiviral - additives used to enhance the
functionality of textiles and polymers. The reduction of bacteria and viruses is a feasible way to help stem the spread of infections including MRSA.

Hexcel’s Leading Position in Aerospace and Automotive Makes Hexcel a Trusted Partner for Urban Air Mobility

At this year’s JEC World in Paris on March 3-5, Hexcel will highlight the growing need for innovations in composite materials to support the emerging Urban Air Mobility (UAM) market.

Urban air mobility – urban transportation systems that move people by air or enable cargo deliveries – is the next big transportation innovation. Similar to taxis or ride sharing today, UAM will help remove congestion from our streets and provide a convenient, rapid method for travel in urban centers as well as in remote areas.

Advanced composite materials will be at the heart of UAM vehicles by providing lightweight, efficient, reliable, and cost-competitive options for manufacturing. “Materials have been a key driver of efficiency for aircraft today, and they will be even more important for the emerging UAM marketplace,” said Imad Atallah, Director of Strategic Marketing for Aerospace and Urban Air Mobility at Hexcel.

Already, Hexcel is a leader in advanced composite materials for the aerospace market and is a key supplier of composite materials to the automotive industry. So, the company is well positioned to offer solutions to meet the critical needs of high-rate and quick-part manufacturing cycles, in addition to low-cost needs for this space. Hexcel’s materials solutions approach for UAM is to make it greener and more sustainable, safer, more comfortable, and more affordable.

Hexcel’s broad range of carbon fiber and HexPly® prepreg solutions, including snap cure thermosets and thermoplastics, coupled with the most qualified positions on aerospace programs in the industry make the company a trusted partner for UAM. In addition to offering composite materials from carbon fibers, prepregs, honeycomb and reinforcements, Hexcel’s best-performing market solution in noise absorption on aircraft jet engines, Acousti-Cap®, provides a strong position of innovation to solve one of the most critical problems in the UAM space – community noise. “We are applying our technologies to the unique needs of urban air mobility vehicles,” Atallah said.

Hexcel’s ability to bring materials technology from the aerospace and automotive industries represents a unique strength in solving the critical challenges of UAM, especially around high-rate manufacturing, low-cost materials, light weighting, and noise. “Both thermoplastics and quick-cure thermoset materials are expected to have applications on UAM vehicles,” Atallah said. Furthermore, Hexcel’s broad product portfolio including unsized carbon fiber has proven to be the most compatible with thermoplastic resins from a consolidation perspective.

At this year’s trade fair „SIMAC Tanning Tech“, PFAFF Industrial, together with DÜRKOPP ADLER and the regional agency DAP ITALIA, will present the latest solutions for shoe and leather processing. The fair will take place in Milan from 19th to 21st of February 2020. The joint booth is located in Hall 14, No. C09.

PFAFF News and Highlights:

PFAFF 3806
New integrated workplace for closing rub-down seams, such as heel-, front- and side seams on street shoes, slippers and leg boots. The PFAFF 3806 is equipped with two-thread chainstitch high-speed seamer head PFAFF 5487 with drop feed and variable top feed, high lift and adjustable top feed pressure, which ensures consistently high quality. Reinforcing tapes, which may be applied from top impart greater durability to the seams and prevent fine leathers from being pulled out of shape. Automatic control sequences (via parameter or photocell) reduce the manual handling and increase the process reliability and output.

PFAFF 1591
On the fair PFAFF INDUSTRIAL will show its electronic single-needle shoe post-bed machine with touch-control panel, new thread trimmer for short thread ends (< 5 mm) and new programmable thread tension. The key benefit of “programmable thread tension” is that suitable thread tensions can be applied for different material thicknesses and/or for different seam sequences (as these can be programmed on electronic machines). The tensions can be accessed and/or set via a knee switch or stitch counting. Manual setting of the thread tension, as is common with current shoe machines, is no longer necessary with the programmed thread tension.

PFAFF 8303i
The ot-air taping machine for welding continuous seams on water-resistant, waterproof and breathable materials will be exhibited as “shoe version” with very small/slim post from back. Effortlessly shoe uppers with small radii can be taped. The slim post and the differential feed (via two separate drive motors for the top and bottom feed roller) ensures absolute neat seams and a requested fullness und shaped parts.
 

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

The origins of both Industry 4.0 and an awareness of the need for more sustainable manufacturing methods can arguably be traced back to the year 1971.

It was in 1971 that the first microprocessor was introduced by Intel, and also that the first and perhaps now most well-known environmental campaigner, Greenpeace, was founded.

As such, a direct line can be charted from that year to today’s automated textile manufacturing machinery concepts, as well as the drive to develop more increasingly resource-efficient processes.

All of the recent innovations which have been introduced to the market by A. Monforts Textilmaschinen GmbH & Co. KG, for example, are being powered by the possibilities of Industry 4.0 and developed in response to the market demand for more sustainable production.

They include the new ‘digital twinning’ capability introduced in 2019 for all Monforts machines, with advanced sensor technologies which make it possible to access comprehensive technical machine data from any location using the company’s Smart Support and Smart Check apps. In addition, the digital twin system provides information on individual wear parts, such as, for example, converters or gears.

These latest developments have been very favourably received by Monforts customers, especially in Europe.

50th anniversary
The very first Heimtextil – the leading trade fair for the home textiles market – was also held in Frankfurt in January 1971 and Monforts customers Bierbaum Group and Konrad Hornschuch AG are amongst the German companies who were there from the very start and have attended every annual show since.

Bierbaum Group, based in Borken, is the company behind the well-known Irisette bedding brand and is celebrating its own 125th anniversary in 2020. It has also introduced products bearing the German government’s new Grüner Knopf textile seal of approval for sustainable production.

As a specialist in synthetic leathers for home surfaces, as well as vehicle interiors, Konrad Hornschuch AG, of Weissbach, has been a member of the €44 billion automotive giant Continental AG since 2016.

Representatives from both companies received memorial trophies at a special presentation held on January 7th during the 50th anniversary Heimtextil show.

The home textiles market remains very strong in Germany, with sales amounting to some €9.6 billion in 2019, according to analyst IFH Cologne.

Global growth
The first Heimtextil in 1971 was a significant success, attracting 679 exhibitors from 26 countries.

This year’s show, however, attracted a total of 2,952 exhibitors from 66 countries, reflecting not only the growth of the home textiles industry, but also the globalisation which has taken place over the last half century.

Monforts now has customers for its advanced finishing technologies around the world, with home textile customers from India and Pakistan being particularly well represented at Heimtextil 2020.

Among stand outs from Indian companies at this year’s show was the 2020 collection of Welspun India’s famous Christy England brand, inspired by botanical studies of the gardens of British stately homes. Welspun towels meanwhile benefit from the company’s HygroCotton hollow core yarn technology, produced by a proprietary spinning method which ensures they become softer, fluffier and more absorbent after every wash.

An equally ground-breaking new technology is being introduced by Trident Group, which is one of India’s largest vertically-integrated home textiles manufacturers and two years ago installed five complete Monforts finishing ranges for its new linen department.

Trident’s patented Air Rich yarns feature pores throughout their cross sections for high breathability and absorbency, as well as rapid drying.

Monforts home textile customers from Pakistan stressed the resource efficiency of their processes and products as a result of investments in advanced technology, and during the show the ‘Sustainable Pakistan’ initiative was announced.

Supported by GIZ, the German Society for International Cooperation, the initiative aims to reshape global perceptions of Pakistan’s manufacturers and their innovations. So far, twenty producers have been carefully chosen to be presented on this global platform and will help rebrand Pakistan’s textile industry at the Heimtextil exhibitions going forward.

Heimtextil’s organiser Messe Frankfurt also announced its own new alliance with the United Nations Office for Partnerships, in order to support the UN’s Sustainable Development Goals.

Constancy
Many things have changed since 1971 and home interiors are certainly no longer predominantly orange and brown – and perhaps unlikely to ever become so again.

It’s clear, however, that there has been a constancy in the push to consistently improve textile technologies, processes and products that may have originated in Europe, but have subsequently spread around the world.

And the significance of both microprocessors and sustainability in 2020 could only have been guessed at back in 1971.

COBRA International is collaborating with HG Robotics, a leading drone manufacturer that specializes in unmanned aerial vehicles (UAVs) for the agricultural market, on a composite fuselage cover for the cutting-edge Tiger Drones.

Undertaking a full range of services with HG Robotics and having been involved from the outset: from the design and engineering through to the prototyping of the composite drone fuselage cover, COBRA has now delivered nearly 100 sets and will produce approximately 500 units throughout 2019.

The multi-rotor Tiger Drones typically carry spraying equipment and can also carry high definition cameras that provide a wide range of field information. Farmers can measure land profiles, identify any problem plants or areas and manage their cultivation in the most efficient way. The 420 mm square shaped fuselage cover protects the drone’s electronic controls and forms an aerodynamic fairing between the central fuselage and the craft’s 4 rotor arms.
 
The COBRA Design and Development team selected a composite laminate of glass fibre reinforcements for the cover – which don’t interfere with GPS signals used by the drone - and combined these with epoxy laminating resins in a hand laminated, vacuum bag consolidated production process.

COBRA also designed all of the mould tools for the project. The 2-piece aluminium mould was produced by one of COBRA’s long-term tooling partners. This metallic tooling provides an excellent surface finish to the part with absolutely minimal trimming and finishing required.   Moulded parts can go swiftly through a painting and clear coating process before final inspection and delivery to the client.

Danu Chotikapanich, CEO of COBRA International comments: “Our collaboration with HG Robotics is going well, and we are hoping to collaborate further with them on other multi-rotor and fixed wing VTOL (vertical take-off and landing) drone models in the future. These are COBRA’s first parts for the agricultural industry, and they provide an exciting vision as to just a few of the possibilities for lightweight composites in this area and also in the wider commercial UAV market as a whole.”
