From the Sector

Mountains of waste, plastic-infested oceans, negative CO2 footprints – the need for more sustainable ways of living has never been more urgent. Consequently, it is logical that recycling solutions are becoming increasingly important within the textile industry. This was also tapped into at the first virtual Global Fiber Congress in Dornbirn with a session that focused specifically on the topic. In front of around 400 participants, Markus Reichwein, Head of Product Management at Oerlikon Barmag, also spoke about solutions currently on the market.

As one of only manufactureres, the Oerlikon Group’s Manmade Fibers segment offers the entire mechanical recycling chain –from preparing the recycled materials, producing the melt all the way through to the textured package. Here, the company utilizes the VacuFil solution supplied by its subsidiary Barmag Brückner Engineering (BBE) –which, in addition to mastering bottle-to-bottle and bottle-to-textile processes, is also able to process textile waste into chips. This permits the running of textile production operations very much in line with the zero-waste philosophy.

VacuFil ensures a stable process in the case of recycled quality yarns
The reliable removal of contaminants is vital for a stable and efficient spinning process and outstanding yarn quality. At the same time, stable operating conditions with minimal fluctuations are essential. The greatest challenge here is the differing qualities of the bottle flakes fed into the system, as the extrusion process is barely able to balance these fluctuations. Here, the VacuFil concept counters with blending silos, which reduce the differences in the viscosity of the polymers considerably and guarantee high yarn and fabric quality.

The VacuFil concept is installed upstream to an Oerlikon Barmag POY system, which transforms the recycled melt into filament yarn of the accustomed high quality. As texturing solutions, Oerlikon Barmag offers its state-of-the-art automatic eAFK-series systems, including the latest generation of the eAFK Evo, which was unveiled at the ITMA Barcelona last year. Yarn manufacturers wishing to continue texturing manually can use the eFK series.

With the VarioFil R+, producers of smaller batches now also have a compact system with an integrated recycled materials preparation unit at their disposal. The system offers a special extrusion system for bottle flake materials, the very latest metering and mixing technology for spin-dying and expanded 2-stage melt filtration. The four spinning positions are each equipped with an Oerlikon Barmag 10-end WINGS POY winder.

While mechanical recycling has already been extensively developed, chemical recycling for mixed fabrics is still presenting the textile industry with huge challenges. The Oerlikon Group’s Manmade Fibers segment is currently working on solutions and concepts for transforming these fabrics into new textiles.

For more than 50 years, vehicle manufacturers have relied within their model development on Autoneum’s measuring systems for vehicle acoustics. With ATLAS, Autoneum has now added another particularly powerful device to the portfolio: Thanks to the efficient and reliable measurement methodology, noise-reducing vehicle components and materials can be analyzed and developed faster and with a significantly lower need for resources in the future.

With the ongoing electrification of vehicles and trends like autonomous driving, future car generations will no longer be used solely for transport – remote working and recreation will equally play a key role. This requires a vehicle interior that is as noiseless as possible. In order to identify and insulate potential internal and external sound sources already in the pre-development of new models, car manufacturers around the world rely on Autoneum’s highly specialized measurement tools. The newly launched ATLAS – short for “Airborne Transmission Loss Analysis System” – measures the acoustic insulation and transmission loss of components such as carpets, inner dashes and floor insulators. This allows customers to assess noise-reducing parts within minutes and select acoustic components tailored to their needs.

ATLAS sets new testing standards in this regard. While developers previously had to analyze the NVH behavior (noise, vibration, harshness) of interior parts using material samples of around one square meter in size, ATLAS makes this process faster, cheaper and more environmentally-friendly. It enables measurements of small samples with a diameter of no more than ten centimeters, which substantially decreases the amount of material used. Thanks to its four highly sensitive microphones, only two trials are required to collect precise and valid test data, making the system developed at Autoneum’s research center in the Swiss city of Winterthur especially suitable for quality assurance and repeatability of the results obtained. Users also benefit from time savings of up to 50 percent compared to the previous testing standard.

Autoneum’s measurement systems represent the global industry standard and are used successfully by vehicle manufacturers, automotive suppliers and research institutions alike. The Company is therefore not only making a significant contribution to the mobility of the future with its noise-reducing products, but now with ATLAS as well.

In the joint project "AeroFurnace" funded by the German Federal Ministry of Economic Affairs and Energy (BMWi), the consortium, consisting of the Bavarian Center for Applied Energy Research e.V. (ZAE Bayern) as joint coordinator, the furnace manufacturer FCT Systeme, and SGL Carbon has succeeded in improving the thermal insulation properties of a new composite material by up to 120 percent compared to commercially available felt-based carbon materials. This enabled the project partners to move into a new quality level of thermal insulation in high-temperature industrial applications and pave the way for more energy efficient thermal insulation.

Dr. Gudrun Reichenauer, coordinator of the joint project and head of the work group Nanomaterials at ZAE Bayern: "In this project, we have been able to make the latest findings from the world of nanomaterials accessible to the market through intensive cooperation and thus set new standards in the field of thermal insulation materials."

Dr. Thomas Kirschbaum, project manager at SGL Carbon: "In furnace simulations at the partner FCT, we have already been able to demonstrate what the new material can do: Depending on the temperature program, up to 40 percent of the required process energy can be saved with the new thermal insulation material. The potential of the new material is great." This prediction will be reviewed under real conditions in a demonstrator component in the second half of 2020 as part of the still ongoing BMWi project.

Dr. Jürgen Hennicke, project lead and head of R&D at FCT Systeme: "As a leading manufacturer of industrial vacuum or inert gas high temperature furnaces, the new generation of insulating materials enables us to create furnaces with a more favorable ratio of usable space to external dimensions, thus offering customers improved cost efficiency and productivity".

Based on laboratory samples in plate form it has already been demonstrated that the production of the new material can be represented by technically simple processes and is in principle well scalable. However, there is still a long way to go before the product is ready for serial production.

The third largest share of final energy in Germany is used for the generation of heat in industrial processes (22.6 percent). In many industries, e.g. in the steel and ceramics industry, energy-intensive high-temperature processes run above 1000°C – these alone require almost 50 percent of the industrial process heat. Suitable thermal insulation materials can significantly reduce energy demand while maintaining the same usable volume.

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.

• 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.”

• Investment of Rp. 15 trillion (USD1,1 billion) in facility
• Supports development of national textile industry and ‘Making Indonesia 4.0’ roadmap

The President of Indonesia, Joko Widodo, today inaugurated Indonesia's largest integrated viscose rayon production facility, injecting a boost for the country’s textile sector and the Indonesian Government’s industrial 4.0 development strategy.

The new Asia Pacific Rayon (APR) facility is located in the same production complex as APRIL Group in Pangkalan Kerinci, Riau province, Sumatra. This co-location allows integrated operations where renewable plantation pulp supply from APRIL feeds directly to APR for viscose rayon production. The new operation represents a total investment of approximately Rp.15 trillion (USD1.1 billion).

The APR facility has an annual production capacity of 240,000 tons. The inauguration ceremony included the signing of a plaque by President Widodo and the symbolic sealing by the President of an export container with 10,190 tons of viscose rayon fibre for shipment to Turkey, one of APR’s key export markets, and another 12,000 tons to Central Java.

The ceremony was also graced by the Minister of Industry, Agus Gumiwang Kartasasmita, the Minister of Trade Agus Suparmanto, the Governor of Riau, Syamsuar, RGE Founder and Chairman Sukanto Tanoto, and Anderson Tanoto, Director, RGE.

Speaking at the inauguration, President Widodo welcomed APR's investment in the development of the national textile industry. The role of the private sector was influential in driving economic growth, alongside the stimulus provided by the Government, he said. “Our garment industry should be greater than Vietnam. We already have our own raw materials here, such as viscose rayon, to support the industry,” he said.

Economic Contribution
APR’s business aligns with President Jokowi's vision to encourage more value-added investment in the nation and the strengthening of the national textile and textile product (TPT) industry, as set out in the Making Indonesia 4.0 Road map. In addition, the production of viscose rayon will reduce dependence on the import of textile raw materials, particularly cotton, to meet domestic demand.

Agus Gumiwang Kartasasmita, Minister for Industry, said: “By optimising the availability and use of raw materials originating from Indonesia, we can boost the performance of our textile sector. This is just one of several steps we are taking to continue to improve the performance and competitiveness of the labour-intensive industry.”

Basrie Kamba, Director APR, said: “The presence of APR will have a positive impact on employment and business opportunities for small and medium-sized businesses in the upstream and downstream sectors of the textiles and textile products industry. We are honoured and grateful to President Jokowi for inaugurating our new facility”.

In addition to Turkey, APR’s products are exported to 14 other countries including key textile centres such as Pakistan, Bangladesh, Vietnam, Brazil, and various parts of Europe. The products also support an expanding Indonesia fashion industry.

It is estimated that APR may generate foreign exchange revenues exceeding Rp1.77 trillion (USD130 million) annually, and reduce dependence on imported raw materials by about Rp2.01 trillion (USD149 million) annually.

Sustainable Production
APR produces sustainable viscose rayon fiber from renewable, traceable and biodegradable raw materials. The company’s raw materials are supplied by APRIL Group, which is recognised as a responsible pulp producer through national (Timber Legality Verification System) and international (Program for the Endorsement of Forest Certification/PEFC) certifications.

APR is the first viscose rayon manufacturer in Indonesia to receive the internationally recognised STeP certification from OEKO-TEX ®, an independent Swiss-based certification organisation, for the responsible manufacturing of viscose staple fibre.

APR has launched the ‘Everything Indonesia’ campaign to promote the sustainable sourcing and production of fashion from Indonesia. The aim is to support Indonesia’s resurgence as a global centre for textile manufacturing, and catalyse home-grown fashion design and creativity.
