From the Sector

Freudenberg Performance Materials (Freudenberg) is presenting its sustainable Evolon® product range for reusable technical packaging for highly-sensitive parts at Fachpack 2022 in Nuremberg, Germany from September 27-29. The microfilament textiles offer improved surface protection for molded plastic parts, painted parts and so-called class A parts, thus providing customers with significant savings potential.

Evolon® RE is the most sustainable product in the portfolio. It contains the highest percentage of recycled PET and has a smaller carbon footprint. The new Ultra Force range from Evolon® offers extremely high mechanical strength and eliminates the need for PVC in the transportation and protection of large, heavy parts. Freudenberg has developed the ESD range (electro-static discharge range) for the packaging of sensitive electronic components: it offers permanent electro-static discharging and its surface resistivity can be customized.

Cobra International, a leading manufacturer of advanced composite products for the watersports, automotive, marine, and industrial sectors, will highlight recent diversification into new composite markets at JEC World 2022, with exhibits ranging from VTOL drones to carbon fibre prosthetics.  Cobra will also demonstrate how it is working alongside automotive and water sports customers to further enhance the sustainability of products in these sectors.

High Volume Production Capacity for the UAV sector
Cobra will display a wing from the Swiftlet UAV. This compact tactical fixed wing UAV platform has a 5.5m wingspan and was developed by the Royal Thai Air Force and National Science and Technology Development Agency (NSTDA) for survey, monitoring and search and rescue operations. Cobra manufactured the 32kg Swiftlet composite airframe using a combination of CNC cut carbon sandwich internal structure and PVC foam sandwich skins using both high grade glass fibre and carbon fibre reinforcements.  

Sustainability Options for Automotive and Watersports
Sustainability has a been a key focus for the Cobra Waterports division and CAC, the Cobra automotive business unit. At JEC World 2022, Cobra will showcase the increasing material and process options it has developed with both bio-resin and natural fibre reinforcements variants presented alongside more traditional carbon fibre parts.

Visitors will be able to get up close to a new Bio SUP Wingfoil board featuring a basalt, flax, bamboo and GreenPoxy bio-epoxy construction created for partners NSP, as well as state-of-the-art compression moulded prepreg foils. Cobra’s first fully recyclable surfboard incorporating the Recyclamine® resin technology that Cobra was recognised for in the 2020 JEC Innovation Awards will also be on display alongside a new Audi e-tron foil by Aerofoils – the world’s safest electric hydrofoil board.

The CAC team (Automotive Business Unit of Cobra) will present a set of OEM mirror cap parts that showcase a range of carbon SMC, woven visual carbon, pure woven visual flax, hybrid flax-carbon and painted flax construction options for the same component.  Clear carbon aesthetic and structural parts including CAC made M-carbon components for the BMW S 1000 RR Motorcycle will furthermore underline the high quality and eye-for-detail for which CAC is renowned.

Carbon Prosthetics
An entirely new composite application for the company, Cobra will also show two composite prosthetic devices at JEC which were productionised by the in-house design and development team. Working alongside a leading Thai university and a medical device OEM, Cobra created a rapid and cost effective series production process for a lightweight carbon fibre prosthetic foot. In another example of lightweight composites creating major quality of life improvements, Cobra has also designed and manufactured a carbon and glass fibre prepreg foot support for Elysium Industries.

Flexibility, product uniformity and automation are the keys to success for coating businesses in today’s rapidly-changing technical textiles industry, explained Jürgen Hanel, Monforts Head of Technical Textiles, at the recent 1st World Congress on Textile Coating.

Introducing the latest Montex®Coat magnetic roller coating option to virtual delegates from around the world at the conference organised by International Newsletters, Hanel explained why this technology makes perfect sense now

“The magnetic roller system allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process,” he said. “It provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater.”

With traditional dip coating systems, he added, as well as with many standard knife coating technologies, there is always a difference in the tension between the centre and the edges of the wide width fabrics being treated – and hence the amount of pressure with which the coating is applied. With the use of a magnetic roller, equal pressure is applied across the full width of the fabric, with consistent results even at wide widths of over 2.4 metres. In addition, adjusting the roller surface, rather than changing the coating formulation to match the required add-on and viscosity for each coating effect required, leads to much higher output from the line.

Cleaner and less wasteful
The contribution of such flexible and resource-saving new technologies to a cleaner and less wasteful textile industry was a key theme at the congress – held virtually across the four afternoons of February 11th, 12th, 18th and 19th – as was digitalization and the many advantages it is providing.

“A typical integrated Monforts coating line is automated from the inlet feed to the winder,” Hanel told delegates. “Adjustments can also be made simply and easily from the touchscreen and with the new hand-held remote controller which has recently been introduced for the Montex®Coat unit.”

Manual adjustment, he added, is time consuming and needs the attention of an experienced operator or the reproducibility will not be accurate between coating operations. The adjustment by motors allows each coating to be stored and downloaded again for 100% reproducibility.

The motors can be fully controlled from the touchscreen and all necessary adjustments carried out remotely, making switching from one process to another extremely quick and easy.
The accuracy that is now being demanded by today’s most exacting customers is met with an optional carbon fibre roller – especially in dealing with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics. Typical applications for the Montex®Coat include the finishing of tents and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments can all be accommodated.

“The World Congress on Textile Coating was characterised by some very stimulating presentations and forums between the speakers and a global audience of textile specialists,” Jürgen Hanel concluded. “It truly reflected the high level of positive changes now taking place in not just textile coating, but the entire textile industry. I look forward to the next edition, which hopefully will be a face-to-face event for even deeper level discussions and debate.”

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

This September’s Cinte Techtextil China will once again provide a strong barometer of the state of the global technical textiles industry, and in particular which sectors in Asia as a whole, and China specifically, are performing well. Two of these for certain are Buildtech and Mobiltech, with a number of leading global and Chinese brands exhibiting to eager buyers from these sectors.

Cinte Techtextil China is Asia’s leading biennial fair for the technical textiles and nonwovens sector, and will feature an expected 500-plus total exhibitors from around 20 countries & regions from 4 – 6 September.
