From the Sector

According to the World Health Organization (WHO), cardiovascular disease is one of the most common natural causes of death. Every year, it is the cause of death of around 17 million people worldwide. The Peter Dornier Foundation Prize 2022 has now awarded a research work that is to improve the medical care of people with insufficient heart valve function in the future and prolong the patients' lives.

The human heart is a high-performance machine: over the course of a person's life, it beats almost three billion times, pumping around 200 million litres of blood through the body. Enormous stresses that can sometimes lead to life-threatening signs of wear and tear. If a heart valve gets out of step, patients usually get artificial-mechanical or biological valves as a replacement. However, mechanical solutions imply patients to take blood-thinning medication for the rest of their lives. In addition, there may be audible closing noises. For example, almost a quarter of patients with mechanical heart valves complain of sleep disturbances. Biological heart valves, on the other hand, such as those made from animal tissue, require a great deal of manual work and have a shorter lifetime.

Potential of weaving for medical products demonstrated
For this reason, Graduate Engineer Mathis Bruns at the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at the TU Dresden is researching an implant alternative made of fabric. As part of a research project that also involved heart surgeons from the Dresden Heart Centre and the University Hospital in Würzburg, Mr. Bruns provided important findings for weaving an artificial heart valve in his diploma thesis. For his work entitled "Development of tubular structures with integrated valve function", Mathis Bruns has now received the Peter Dornier Foundation Prize 2022, endowed with 5,000 euros. In his laudation, Dr. Adnan Wahhoud, former head of the development department of air-jet weaving machines at DORNIER in Lindau, said: "With his work, the winner of the award demonstrates very clearly the potential of weaving technology to produce fabrics of complex form, geometry and structure with the aim of prolonging and improving people's lives." The award-winning thesis enriches research into three-dimensional tissues for use in medicine.

Weaving replacement heart valves without seams
"A particular advantage of our approach is the integral production method", says foundation prize winner Mathis Bruns. “The geometry and function of a heart valve is that complex that woven heart valves could not be produced in this form previously. Through the combined use of a rigid rapier weaving machine with bobbin shield and a Jacquard machine, it is possible to weave the replacement heart valve in such a way that it no longer has be sewn together. Even the tubular structures for the blood vessels and the integrated valve function are ‘all of one piece’. Seams are always a weak point in textile medical products," Mr. Bruns adds. “Another advantage of the woven heart valve is the possibility to insert it by the help of minimally invasive surgery. Hence, the folded valve which is about the size of a tea light is to be pushed with a catheter via the bloodstream to the target position in the heart and unfolded there. The patient's chest and heart would then no longer have to be cut open”, explains prize winner Mr. Bruns.

Textile structure is similar to human tissue
A wide variety of medical products have always been produced on DORNIER weaving machines. Customers use them to produce fabrics for bandages, prostheses, blood filters and orthoses among other things. For Mathis Bruns, it is only evident that implants such as heart valves will more and more be woven on the machines from Lindau in the future. "Textile tissue is very similar to human tissue," he says. The human body consists largely of thread-like materials, just as a textile fabric is made up of thousands of individual threads. "Muscle fibres convey force impulses, nerve tracts send stimuli such as pain and brain cells convey information via thread-like dendrites and axons." Because of their ‘thread-like properties’, woven implants are therefore particularly suitable for medical applications.

ANDRITZ will be presenting its innovative nonwovens production solutions at CINTE 2022 in Shanghai, China (September 6–8). ANDRITZ will show its broad product portfolio covering state-of-the-art nonwovens and textile production technologies such as air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, recycling, and natural fiber processing.

SUSTAINABILITY IS KEY

It designs and manufactures cutting-edge lines to complement the ANDRITZ aXcess product range, which includes complete lines and individual machines for air-through bonding, needlepunch and spunlace processes. With the aXcess range, ANDRITZ has developed a hybrid line combining European and Chinese machines, which is the ideal combination to obtain the best added value from each component in the line and be very flexible to accommodate different business cases.

The service organization was set up to provide prompt delivery and excellent customer support, even during the COVID-19 pandemic. A team of technicians and process experts can be deployed quickly to customer sites requiring full-range assistance. The ANDRITZ facilities include a roll service center with state of-the-art grinding equipment and a test stand for various types of rolls.

In addition, our aXcess range manufactured in Europe also offers technologies for spunlaid and wetlaid processes. Increasing production speeds and widths, compact and reliable design, and affordable investment costs are what customers look for in a competitive market environment. To meet these requirements ideally, we recently enhanced our nonwoven calender and dryer ranges.

The Japanese textile manufacturer ECOSENSOR™ by Asahi Kasei Advance presents its SS 2023 collection, made of high-tech fabrics implementing new-generation values, with the aim of keeping nature, body and mind in harmony.

ECOSENSOR™ presents 40 new references that meet the needs of the contemporary consumer, such as durability, wellbeing and performance. Being capable of combining active climate control, exquisite touch, lightness and comfort with sustainable values, ECOSENSOR™ stands out as a unique eco-high-tech performance proposition in its market. The collection covers the different market applications with 7 items for INNERWEAR, 2 for OUTERWEAR, 17 for SPORT KNIT and 14 for SPORT WOVEN.

Furthermore, all of ECOSENSOR™ fabrics are made with sustainable materials which are certified by internatinal certification such as GRS, RCS or self-certification by each yarn supplier, through a traceable and transparent production process and supply chain.
100% of the stretch articles (representing 35% of the collection) are made with ROICA™ EF by Asahi Kasei, the recycled stretch yarn made from pre-consumer materials.

The main fibers are GRS certified recycled polyester and recycled polyamide, but the collection also features some blends, such as in Bemberg™, the high-tech yarn born from the transformation of cotton linters through a circular, transparent and traceable process with a precious hand, optimal moisture management characteristics,  whose end of life guarantees its biodegradability.
Even the dyeing and finishing phases have been certified by international labels such as bluesign® or OEKO-TEX® Standard 100.

Monforts is introducing a range of modular upgrades that can be added to existing finishing lines already in production.

The Monforts universal Energy Tower – a flexible, free-standing air/air heat exchanger for recovering the heat from the exhaust air flow of thermal processes – can result in a 30% reduction in the energy consumed by a line, depending on the exhaust air volume and operating temperature.

A Monforts Eco Booster, completely integrated into the chamber design of the Montex stenter, is another retrofitting option. As a single state-of-the-art heat recovery system with automatic cleaning, it can be added to existing ranges. For ranges of up to eight chambers only one module is necessary to achieve significant energy savings.

On an eight-chamber stenter with an operating width of two metres carrying out a fixing process on a 150gsm woven fabric, for example, the energy savings have been calculated to be 35% over an annual schedule of 6,000 operating hours.

In addition, the Eco Booster consumes only minimal amounts of water during the cleaning cycle and the entire process is controlled and monitored automatically.

The Matex Eco Applicator is an alternative to the conventional padding process for energy-conscious finishing and achieving considerable savings in the energy required for drying treated fabrics. The precise amount of chemical can be applied to the fabric and with less residual moisture after application of only approximately 35% so that less drying capacity is required in the stenter, which leads to huge energy savings.

Finishes can be evenly applied on either or both sides of the fabric, and two separate treatments can be applied to front and back. This makes the unit ideal for the production of, for example, double-performance hydrophobic/hydrophilic fabrics for professional clothing, as well as the over dyeing or finishing of denim fabrics.

The Reifenhäuser Group will be represented with four booths at the world's leading trade fair for plastics processing, K 2022, from October 19 to 26. Under this year's Reifenhäuser motto "The Time is Now", the extrusion specialists will show producers of films and nonwovens solutions for the three major topics of the industry: sustainability, digitalization and productivity.

The main booth showcases the Reifenhäuser Blown Film, Cast Sheet Coating and Reicofil business units. With the help of machine exhibits, visual presentations and concrete solutions for end products, visitors will learn, among other things, how they can manufacture fully recyclable products economically, process recyclates safely, increase their output and network the entire production without becoming dependent on systems, specialists or manufacturers. To ensure smooth production even after purchase, Reifenhäuser Service shows how customers can get the best out of their Reifenhäuser products and increase their productivity with rework solutions, modifications, training programs and digital services.

The component specialists of the Reifenhäuser Extrusion Systems business unit will additionally present their portfolio at two other exhibition booths. Here, everything revolves around screws, barrels and extruders - and why, especially for processing recycled material, high-performance wear protection is essential for reliability and high economic efficiency. Reifenhäuser Extrusion Systems will also showcase its innovations for flat dies and coextrusion blocks and their coordinated interaction for maximum productivity.

In addition to its own booths, Reifenhäuser will also be present as a partner of the R-Cycle initiative as part of a joint pavilion on the open-air site in the so-called Circular Economy Forum. R-Cycle is a cooperation project of various technology companies and organizations along the entire life cycle of plastic packaging.

Aanother highlight for visitors to the Reifenhäuser trade fair booths is the opportunity to additionally participate in the in-house exhibition on October 20, 21 and 24 at the Reifenhäuser Technology Center.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, along with its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will be participating in the Techtextil exhibition in Frankfurt, Germany from the 21st till the 24th of June 2022.

On display will be SHIMA SEIKI’s latest innovation in flat knitting technology as applied to the field of technical textiles—a prototype weft knitting machine capable of multi-axial yarn insertion. Fabrics produced on this machine use inlay technique for the production of hybrid textiles that combine the stretch characteristics of knitted fabrics with the stability of woven textiles, suited to various technical applications. To this, warp yarn is inserted to further expand its capability to produce 3D-shaped carbon fiber and composite preforms directly on the machine. This is made possible by taking advantage of the fact that flat knitting as a textile production method is capable of producing end products that are shaped-to-form and with added thickness. Compared to current methods of preform production, savings in post-processing time, material, labor and associated costs are immense, realizing efficient and sustainable production. SHIMA SEIKI’s own yarn unwinding technology is also used for optimum yarn feed and tension for use with technical yarns that are otherwise difficult to knit. Industrial textile samples knit on the multi-axial machine will also be available for examination on-site.

SHIMA SEIKI's SDS®-ONE APEX4 3D design system will be available for demonstrations as well. Of particular interest should be its ultra-realistic simulation capability that realizes Virtual Sampling. When countless variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time, cost and material normally associated with producing actual samples for each variation. When approved, the same data can be converted to machine data for immediate knitting, significantly reducing lead times.

Archroma will be at Techtextil 2022 in Frankfurt am Main, Germany, from 21 to 24 June 2022, to launch its latest innovations and system solutions aimed to help textile manufacturers with optimized sustainability, productivity and value creation in their markets.

As a leading company in the collecting, sorting, reselling and recycling of post-consumer textile waste, TEXAID has enabled the recycling of post-consumer textile waste into new textiles and clothing. After two years of development, the company has developed a fabric including 50 % of post-consumer textile waste from used clothing, collected and prepared for recycling by TEXAID.

Today’s linear system of «take – make – waste» needs to change. New textiles are produced, used and discarded instead of putting them to a second use. The production of new textiles requires natural resources that are limited, and the current system has a significant negative impact on our planet. The transition to a circular system, where garments are kept in use for longer, is an opportunity to harness untapped potential around customer loyalty, economic growth, and ecological sustainability.

To move away from the linear system and enable products to be made out of post-consumer textile waste, TEXAID invested in the textile-to-textile recycling and product development.

Collaboration enables recycling
After two years of research, product development, and most important, building partnerships in the value chain, TEXAID has been able to develop a fabric made of 100 % recycled fiber in close collaboration with our value chain partners.

The fabric is a blend of 50 % post-consumer textile waste that TEXAID has collected in Germany and Switzerland. White cotton textiles which cannot be worn, have been sorted out in a sorting facility in Apolda, Germany. The other 50% is made from ocean-bound plastic waste which is plastic with a high risk of entering the ocean which has been saved and recycled by Unifi. The fabric and bag have been produced in Italy. The cotton material has been shredded by Marchi & Fildi in Biella, IT, who then spun the recycled cotton and recycled polyester fibers into a yarn. This yarn has been woven into a fabric by Tessitura Casoni.T.F.C.

Through this proof of concept, it has been showcased that making fabrics of 100 % recycled content and with 50 % of post-consumer textiles is possible. TEXAID is looking for strong industry partners to push high-value textile to textile recycling technologies in joint projects like these.

With global consumers becoming more conscious about personal hygiene and environmental protection, exhibitors at Cinte Techtexil China will spotlight materials and technologies for products that respond to these trends. The fair will probe into the associated growth opportunities as the country is one of the leading markets for nonwovens and technical textiles. The event will be held from 6 – 8 September at the Shanghai New International Expo Centre.

The technical textiles and nonwovens industries, the latter notably, are significantly expanding amid the pandemic. A recent forecast[1] predicts that the global polypropylene nonwoven fabric market will continue to rise at a CAGR of 6.7%, reaching USD 39.23 billion by 2028. The anticipated growth is bolstered by demands in end-use industries such as sanitation, medical, automotive and more. In 2020, Asia Pacific was named the largest regional market in the world and is expected to grow significantly over the forecasted period.

The prediction reaffirms the growth prospects of nonwovens. In this regard, industry players expressed much optimism about associated future opportunities during Cinte Techtextil China last year. “The field of nonwovens is poised for a positive growth as the awareness of personal hygiene and pandemic prevention sustains in the domestic market,” commented Mr James Gao, Head of Marketing and Textile Technologies, Uster Technologies (China) Co Ltd. He added: “We decided to join the fair and showcase our new launches as we remain confident in the future development of the industry, especially since China is dominating the global scene.”

Going green is the way forward
Turning to yarns and fibres, the sector is shifting to greener and smarter production that echoes the trend towards sustainability that is gaining considerable traction across the globe. Meanwhile in China, this movement was observed by many exhibitors at the 2021 edition, including Mr Roberto Galante, Plant Manager of FMMG Technical Textiles (Suzhou) Co Ltd, the Chinese subsidiary of the Fil Man Made Group. He mentioned: “The market is paying more attention to environmental protection, and we receive enquiries about special yarns for this every day. We focus on technical yarns for filtration as well as anti-bacterial properties, which are very important for the environment. The potential here in China is incredible and this is a big opportunity for everybody.”

Cinte Techtextil China’s product categories cover 12 application areas, which comprehensively span across a full range of potential uses in modern technical textiles and nonwovens. These categories also cover the entire industry, from upstream technology and raw material providers to finished fabrics, chemicals and other solutions. This scope of product groups and application areas ensures that the fair is an effective business platform for the entire industry.

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.
