From the Sector

• 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.

ANDRITZ has received an order from Manifattura Fontana, part of Sioen Group, to supply a complete neXline needlepunch line for the production of geotextiles to its site in Romano d’Ezzelino, Italy. Start-up of the line is planned for the fourth quarter of 2022.

The ANDRITZ needlepunch line will cover all process steps from fiber opening to automatic packaging of the product. The line will also include the latest ProWin profiling technology to enhance web weight evenness on cards and crosslappers. Another important feature is waterproof roll packaging, which is increasingly in demand on the market. Thus, Manifattura Fontana will be one of the very few players in the world to deliver fabric rolls with waterproof protection.

This will be the second line in only three years to be supplied by ANDRITZ to Manifattura Fontana. Manifattura Fontana is part of the Belgian technical textile group Sioen Industries. It is a leading company in the global geotextile market and provides its customers with added-value geotextiles for many applications, such as the construction of roads, railways, reservoirs, dams, and tunnels, as well as for earthworks, foundations, erosion control, drainage, waste disposal, or containment.

Cone Denim®, a leader in denim authenticity and sustainable innovation, launches a new U.S. grown hemp denim collection in collaboration with expert hemp processing innovator, BastCore. Cone is excited to expand its sustainable denim offerings and increase its support of the American agriculture industry, featuring denim made with Alabama hemp and U.S. cotton and dyed with natural indigo grown in Tennessee.

Cone Denim is honored to partner with BastCore, a team that aligns with Cone’s values and its commitment to innovation, quality, sustainability, and traceability. The pioneers at BastCore have created patent-pending technology and a proprietary process that produces clean, mechanically processed, OEKO-TEX® STANDARD 100 certified and USDA bio-preferred hemp fiber out of its operation in Montgomery, Alabama.

Cone’s U.S. Hemp Collection includes a range of fabrics featuring classic 3×1 and comfort stretch to modern workwear constructions. The collection further expands upon Cone’s sustainability and traceability practices, driving the future of the industry. The proximity of the hemp, indigo, and cotton crops in the U.S. to the company’s mills in Mexico is also key in creating the smallest environmental impact and footprint possible.

Hemp offers many key benefits in creating the next level of sustainable denim:

• More than 50% water savings occur, compared to cotton
• No chemicals, wet processing, pesticides, or herbicides are used
• Hemp grows in a variety of soils with excellent biodegradability, is antimicrobial, has high tensile strength, moisture regain content, and tenacity
• Hemp and natural indigo crops have high rates of carbon sequestration, which ultimately benefits the environment and improves the soil’s health for other crops (climate positive)

Construction machinery rolls into action again. The ground-breaking ceremony at the EREMA site in Ansfelden on April, 6 signals the start of work on a new R&D centre. Two halls with a total area of 1,550 square metres and a new office building with 50 workplaces will be built. The R&D centre will offer cross-departmental and cross-company test machines and laboratory for research and development of plastics recycling technologies to further advance the circular economy. Completion is scheduled for February 2023.

Plastics recycling is currently evolving very rapidly from a niche to a trend. This is driven by the legislative targets for plastics recycling that the European Union and many countries around the world have enacted, as well as by the European Green Deal, which aims to make Europe the first climate-neutral continent and in which the circular economy plays a very central role.

However, there is not just one recycling solution for all types of plastic waste, but rather different solutions depending on the type of plastic, the product and the application intended for the recycled plastic. While some plastics processing loops, such as for PET bottles, have already been closed, many other plastic waste streams still require a great deal of R&D in cooperation with everyone involved in the value chain to produce recycled pellets that meet the very highest standards for the production of new products. More space will be available for this in the new centre.

R&D is decentralised at EREMA. In recent years, approximately 5 percent of turnover was reinvested annually in research and development. Employees from different departments handle process engineering challenges, innovations in mechanical engineering and automation technology, and special technologies with a view to further improving the quality of recycled pellets. They also focus on new recycling technologies for waste plastic materials for which there is currently no satisfactory circular economy solution. The decisive factor here is also to exploit the potential of digitalisation. By collecting and analysing machine data, not only can recycling processes and product quality be further improved, but we can also develop our digital service offering for our customers. Such offerings include customer-specific information tools that feature plant and process data, predictive maintenance and online support as well as commissioning via remote access.

For material tests, which are necessary for research and development work, an expanded machine park will be available following completion of the new R&D centre. Here, the recycling process can be evaluated end-to-end, including upstream and downstream processes such as shredding and further processing of the recycled pellets. The material tests are supported by detailed analysis in the professionally equipped laboratory, which will be relocated to the new premises and upgraded where necessary with the very latest lab equipment.

In 2021, nonwovens production in Greater Europe increased in volume by 2.0% to reach 3,120,967 tonnes (and 87.6 billion square metres).

EDANA, the international Association serving the nonwovens and related industries today released its statistics on Nonwovens Production and Deliveries for 2021. Following the impressive growth recorded in 2020, the updated figures for Greater Europe (incl. Western and Eastern Europe countries, Turkey, Belarus, Russia and Ukraine) highlight again the ability of the European industry to innovate and to invest in order to meet the challenges of the pandemic crisis.

In 2021, nonwovens production in Greater Europe increased in volume by 2.0% to reach 3,120,967 tonnes (and 87.6 billion square metres). Since 2019, the European output increased by nearly 9%.

Jacques Prigneaux, EDANA’s Market Analysis and Economic Affairs Director commented “This 2% average growth is in line with European forecasts disclosed in October 2021 in our Global Nonwoven Markets 2020-2025 report. In 2021, significant growth areas for nonwovens were recorded in building construction (+17.4%), agriculture (+11.3%), electronic materials (+10.1%) and air filtration (+9.1%). Countering this, a further decline of -1% was recorded in automotive interior applications. In some market segments, a comparison with the pre-COVID situation is probably more relevant. This is particularly true in hygiene, medical and wipes nonwovens, which were almost flat or slightly decreasing compared to the level reached in 2020, but still much higher than in 2019”.

He added: “Looking at the different production processes of nonwovens, various trends were observed in 2021. The production of fiber-based materials, including Drylaid, Wetlaid, and Airlaid technologies, recorded divergent growth rates (respectively +2.4%, +1.1% and -4.8%), and spunmelt nonwovens recorded a growth rate of +3.1%. In Drylaid, the highest growth in tonnes was observed in needlepunched, with a 6.4% increase. The production of drylaid-hydroentangled, which peaked in 2020, was at the same level a year later”.

The Trevira CS brand was showcased on the German Pavilion at the BIG Show Oman, an international exhibition for building materials, construction equipment, and interior design, in Muscat, Oman. This year, BIG Show, which is part of Oman Design & Build Week, was held from March 14-16.

Trevira CS has been part of BIG Show for years, as it is an important meeting point for the exhibiting companies with interior designers, construction companies, and project managers. Important authorities from the Middle East as well as major hotel brands were present again this year. In the Middle East, important tenders for major projects are due this year. The main focus of the trade show will be on the hotel & catering and hospital & care sectors, for which Trevira CS fabrics are of great interest because they meet the safety requirements that are usually required by law.

Trevira CS presented its extended brand concept that offers customers even more flexibility and also addresses sustainability. Building on to the high brand quality and performance, the recently introduced brands Trevira CS flexand Trevira CS eco offer properties and functions tailored to specific requirements. Furthermore, the Trevira CS Bioactive brand compliments the range, combining flame retardancy with antimicrobial properties. Fabrics bearing this brand meet the requirements for preventive fire protection and increased cleanliness.This brand concept is very well received by Trevira's customers. Many new flame retardant fabric developments embracing one of the Trevira CS brands were on display at BIG Show.

• Project delivered on schedule and at budget after two and a half years of construction despite challenges arising from a global pandemic
• New state-of-the-art lyocell plant with a capacity of 100,000 tons will help serve the growing demand for sustainably produced fibers
• Important milestone towards a carbon-free future has been set

The Lenzing Group is pleased to announce the completion of its key lyocell expansion project in Thailand. The new plant, one of the largest of its kind in the world with a nameplate capacity of 100,000 tons per year, started production on schedule and will help to even better meet the increasing customer demand for TENCEL™ branded lyocell fibers. For Lenzing, the project also represents an important step towards strengthening its leadership position in the specialty fiber market and into a carbon-free future.

The construction of the plant located at Industrial Park 304 in Prachinburi, around 150 kilometers northeast of Bangkok, started in the second half of 2019 and proceeded largely according to plan, despite the challenges arising from the COVID-19 pandemic. The recruiting and onboarding of new employees has been successful. Investments (CAPEX) amounted to approx. EUR 400 mn.

“The demand for our wood-based, biodegradable specialty fibers under the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ brands is growing very well. In Asia in particular, we see huge growth potential for our brands based on sustainable innovation. With the production start of the lyocell plant in Thailand, Lenzing reached an important milestone in its growth journey, supporting our ambitious goal to make the textile and nonwoven industries more sustainable”, said Robert van de Kerkhof, Member of the Managing Board.

In 2019, Lenzing made a strategic commitment to reducing its greenhouse gas emissions per ton of product by 50 percent by 2030. The target is to be climate-neutral by 2050. Due to the established infrastructure, the site in Thailand can be supplied with sustainable biogenic energy and contribute significantly to climate protection.

Together with the key project in Brazil and the substantial investments at the existing sites in Asia, Lenzing is currently implementing the largest investment program in its corporate history (with more than approx. EUR 1.5 bn). Lenzing will continue to drive the execution of its strategic projects, which are to make a significant contri-bution to earnings from 2022.

Over 600 delegates from 58 countries subscribed to the latest VDMA textile machinery webinar on sustainable dyeing held on February 3rd, 2022 – a record since the monthly online series started in June 2020. The webinar, entitled ‘Resource-saving in Textile Processing – Continuous Dyeing and Washing’, involved the three companies Monforts, DyStar® and Goller.

In outlining the capabilities of Monforts Thermex hotflue lines for the Econtrol® continuous dyeing process, the company’s Textile Technologies Engineer Jonas Beisel observed that the current industry focus is very much on cleaner processes and products in accordance with the Corporate Social Responsibility (CSR) commitments of the major fashion brands, and with further regulations to be expected.

Cellulosics
Econtrol® is a continuous process for the dyeing of woven cellulosic fabrics that has already been well proven on the market, with over 150 Monforts Thermex lines already in operation at mills worldwide.

Reactive dyestuffs are fixed into the fabric in a one-step dyeing and drying process with a controlled combination of steam and air. The entire pad-dry process takes just two-to-three minutes at a temperature of between 120-130°C and a relative humidity volume of 25-30%.

Benefits
The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step.

Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

Complementary services and systems
Complementing the Monforts presentation during the webinar, Bertram Seuthe, Global Business Development Manager at DyStar, outlined the importance of specific Levafix® /Remazol® reactive dyes and Dianix® disperse dyes for sustainable dyeing processes such as Econtrol®, Cadira® Continuous and CPB knit. In these processes Sera® auxiliaries are also employed for optimised wash-off results.

Guido Seiler, Area Sales Manager at Fong's Europe, also introduced the latest developments of the Goller brand for the washing process, which can reduce water consumption by between 10 to 20%, as well as reductions in both heating energy and waste generation, depending on the specific fabric construction and required shade.

For more than 70 years BRÜCKNER has been in the construction of drying and finishing lines for the textile and nonwovens industry. In the nonwovens sector, the company supplies worldwide thermofusion ovens, dryers, coating and heat-setting lines. On the IDEA 2022 trade fair in Miami, USA, BRÜCKNER presents together with its American representation FI-TECH new machine concepts and solutions for different applications in the mentioned fields.

The production of nonwovens always requires a bonding process after the nonwovens formation, where the loosely laid fibers are bonded to a resilient fiber composite. For this purpose, depending on the process, different ovens and dryers are used. BRÜCKNER supplies the necessary lines for all applications. The production program is completed by different impregnation and coating units as well as slitting and winding equipment. BRÜCKNER's customers produce geo nonwovens, filter media, hygiene and medical textiles or different fabrics for the automotive and transport industry

For the production of highloft nonwovens the double-belt thermofusion oven SUPRA-FLOW BX is used. This oven system operates according to the air-through principle and can be perfectly adapted to the product requirements in terms of flow speed, flow direction and temperature on a field-by-field basis.  
The SUPRA-FLOW BX can produce nonwovens up to a thickness of 280 mm and a basis weight of max. 8 kg/m². The available working widths vary between 2400 and 5200 mm at production speeds of up to 100 m/min.  
For geotextile projects, the POWER-FRAME stenter is usually used, which impresses with its uniformity in terms of temperature distribution as well as productivity. In addition, the fabric can be stretched in a targeted manner by transporting it in the stenter chain. This has a controlled influence on fabric width, fiber orientation and fabric shrinkage. Working widths of up to over 7 meters are not uncommon with geotextile finishing systems.

ISKO’s 2023 Collection Vol. 1 is designed to meet the varied needs of today’s consumer by providing fashion, comfort, versatility and responsibility in each of its innovative fabrics. The entire collection is “engineered for nature” using ISKO’s recently launched R-TWO™50+ technology – a process which creates high-quality denim that is less harmful to the natural world.

R-TWO™50+ is the driving force behind ISKO’s efforts to reduce the industry’s impact on the planet. The fabrics are made with a minimum of 50% pre- and post-consumer recycled blend that is entirely Global Recycled Standard (GRS) certified. This results in less use of natural resources and a reduced carbon and water footprint of up to 45% and 65% respectively.

ISKO has also incorporated hemp into the collection as a sustainably viable alternative to cotton. Hemp requires much less water, no pesticides and grows quickly in almost any type of soil. New spinning techniques give the fiber a softer hand feel and make hemp a genuinely enticing option to cotton.

2023 Collection Vol. 1 includes ISKO Blue Skin™, Jeggings™, ISKO™ Rigid, ISKO Rigidflex™, ISKO EFD™, Summer Colors, Catwalk, ISKO Reform™, ISKO™ Black, ISKO™ Comfort, ISKO Pop™ – and five macro trends (Denim Nation, New Origin, Isko Reborn, Isko Motion, Chill Zone). These trends incorporate some of ISKO’s key denim technologies to create a versatile collection that complements any style, vibe and mood.

ISKO Reform™, ISKO Blue Skin™ and Jeggings™ are the groups used to create fabrics that are trans-seasonal and one-size-fits-all – subscribing to a philosophy of inclusivity that is valued by Gen Z.

The collection also gives prominence to color groups. ISKO™ Black delivers various shades of black with different elasticity and aspect options. This part of the collection fulfils the perennial need for this timeless color. ISKO EFD™, or ‘Eco For Dye’, is a sustainable approach to producing ecru fabric. This technology shortens the production process and saves on water usage. The result is an ecru-colored base that can be used as is for a natural look or can also be dyed to any color.

New this season are the Summer Colors and Catwalk groups. Summer Colors is inspired by an eclectic mix of influences including natural earth tones, workwear looks or bright colors with authentic, open-end denim constructions. Catwalk is a bold and bright addition to the collection that offers on-trend styles in ISKO finishes including ISKO Urban Jeather™, Pearl Coat and Flashy Finish.
