From the Sector

Polyester and its applications are omnipresent in our everyday lives. Whether as beverage bottles, film packaging, high-tech sports shirts or safety belts, polyester excels with its excellent mechanical properties and inexpensive production. However, the constantly rising demand requires responsible handling of global resources. For this reason, it is not only ‘virgin polyester’ generated from crude oil that is exclusively the raw material for manufacturing, so too is polyester recycled from post-production and post-consumer waste. Processing production waste also helps cut raw material, disposal and transport costs, hence increasing efficiency.

BB Engineering has developed an innovative solution for the recycling of post-production polyester fibre waste, called VacuFil. Decades of experience in the areas of extrusion, filtration and spinning systems have been bundled into a new, innovative core component – the vacuum filter. It unites gentle large-scale filtration and controlled intrinsic-viscosity build-up for consistently outstanding melt quality. The attached vacuum swiftly and reliably removes volatile contamination and ensures a controlled IV-increase. Comprising an inline viscosity measuring unit connected with the vacuum unit the IV can be controlled continuously and reliably. Hence, producers are able to generate that specific kind of recycled polyester they need for their application.

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 Oerlikon Nonwoven. The meltblown technology from Neumünster is recognized by the market as being one of the technically most efficient methods for producing highly-separating filter media made from plastic fibers.

Protective equipment demands high-end nonwoven products
The rising demand for protective masks and other medical protective equipment since the start of the coronavirus pandemic and the associated global ramping up of production capacities has also resulted in an increase in the demand for nonwovens for the production thereof. Initially, this resulted in bottlenecks in the provision of meltblown filter nonwovens. To this end, there had until this point be very few producers of medical filter nonwovens outside China. Meanwhile, the demand for spunbond systems is also rising. “Due to the structure of our group, we are in the fortunate position to swiftly reallocate and free up our production capacities. This means that we are able to relatively quickly deliver not only meltblown systems, but also spunbond equipment”, explains Dr. Ingo Mählmann, Head of Sales & Marketing at Oerlikon Nonwoven, talking about the positive situation at the company.

The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems. “Our machines and systems for manufacturing manmade fiber and nonwovens solutions enjoy an outstanding reputation throughout the world. Ever more manufacturers in the most diverse countries are hoping to become independent of imports”, comments Dr. Mählmann. The Oerlikon Nonwoven meltblown systems are being delivered to Germany, China, Turkey, United Kingdom, South Korea, Italy, France, North America and – for the very first time – to Australia until well into 2021.

Quality and efficiency in demand
Depending on the purpose of the application, medical PPE (personal protection equipment) should be breathable and comfortable to wear, protect medical staff against viruses, bacteria and other harmful substances and form a barrier against liquids. For these reasons, they are often made of either pure spunbond or of spunbond-meltblown combinations. Here, the meltblown nonwoven core assumes the barrier or filter task, while the spunbond has to retain its shape, while being tear-resistant, abrasion-proof, absorbent, particularly flame-resistant and nevertheless extremely soft on the skin.

All masks are not created equal – thanks to the ecuTEC+
Protection against infections such as coronavirus can only be guaranteed with the right quality.

The nonwovens can be electrostatically-charged in order to further improve the filter performance without additionally increasing breathing resistance. Here, Oerlikon Nonwovenʼs patented ecuTEC+ electro-charging unit excels in terms of its extreme flexibility. Nonwovens manufacturers can freely choose between numerous variation options and set the optimal charging method and intensity for their specific applications. In this way, even the smallest particles are still attracted and reliable separated by a relatively open-pored nonwoven. Nevertheless, mask wearers are still able to easily breathe in and out due to the comparatively loose formation of the fibers. To this end, it comes as no surprise that all meltblown systems currently destined for the production of mask nonwovens are equipped with the ecuTEC+ unit.

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

a leading Asian large-scale manufacturer of manmade fibers and polymers has invested in a new Oerlikon Nonwoven meltblown system. The recently-signed contract comprises a 2-beam system for manufacturing filtration nonwovens – predominantly for medical products such as face masks – with a nominal capacity of up to 1,200 tons of nonwovens a year. The commercial production launch has been scheduled for the fourth quarter of 2020.

The 2-beam system has an operating width of 1.6 meters and is equipped with the new patented Oerlikon Nonwoven electro-charging unit. The Oerlikon Nonwoven meltblown technology is recognized by the market as being the technically most efficient method for producing highly-separating filter media made from manmade fibers, particularly in conjunction with electrostatic charging and with extremely low-pressure loss. Electro-charging the filter nonwovens allows the manufacture of sophisticated EPA- and HEPA-class filter media as well as media that comply with the requirements of N95-, FFP2- and FFP3-class respiratory masks.

The demand for filtration nonwovens for medical applications has risen tremendously across the globe since the outbreak of the Sars-CoV-2 (coronavirus) epidemic, presenting all manufacturers with huge challenges. A meltblown system will be commissioning at the site of a leading Western European nonwovens producers as early as the second quarter of 2020. This system will be deployed exclusively in the manufacture of nonwovens for respiratory masks.

Due to the current state of emergency with regards to the local supply of face masks, Oerlikon Nonwoven is currently using its own laboratory system to produce electrostatically-charged filter media which are being sent to local small businesses and companies for the manufacture of face masks. 

In the latest technology innovation from members of TMAS (the Swedish textile machinery association), ACG Kinna and ACG Nyström have teamed up with Juki Corporation – the world’s leading sewing machine manufacturer – in the development of a new automated line concept that can considerably speed up the production of finished filter bags.

Woven or nonwoven filter bags employed in a wide range of industrial processes may be under the radar as products, but they represent a pretty significant percentage of technical textiles production.

According to a recent report from BCC research, a leading US analyst covering this sector, industrial filtration represented a $555 million market in 2019 and some of the key areas where such filter bags are employed include:

• Metal fabrication, with effective filtration required for manual and automated welding, thermal cutting, blasting and machining, especially for coolant filtration.
• The process and energy industries, including foundries, smelters, incinerators, asphalt works and energy production plants.
• Other key manufacturing fields – often where dust is generated – including the production of timber, textiles, composites, waste handling and minerals, in addition to chemicals, food production, pharmaceuticals, electronics and agriculture.

Line integration
The new SFL-2000 line is the result of a four-year development project between Juki Central Europe, headquartered in Poland, and the two ACG companies.

It is capable of handling a wide range of different filter media, and as an all-in-one solution, can produce high quality and accurate seams to pre-defined parameters, with optional modules allowing for customised constructions.

Monforts Textilmaschinen GmbH & Co. KG will be providing information on its extensive range of coating and finishing technologies for the production of nonwovens and technical textiles at the forthcoming Techtextil India exhibition.

“India is already a very important market for Monforts and there are exciting prospects ahead for Indian manufacturers of technical textiles, who are well positioned to capitalise on growth opportunities,” says Monforts Head of Denim Hans Wroblowski, who will be at the Monforts stand in Hall 4, booth C52 at the show. “India has one of the largest working-age populations in the world and a complete textile value chain for both natural and synthetic fibres.”

In addition, he adds, India’s government, through its Ministry of Textiles, has been actively promoting the growth of technical textiles through various programmes based on investment promotion, subsidies, the creation of infrastructure and the stimulation of consumption.

As a result, India’s Ministry of Textiles is forecasting that the growth of technical textiles in the country will be over 18% annually in the next few years, from a value of US$16.6 billion in 2018 to US$28.7 billion in 2021.

Value addition

High value-added technical products such as wide-width digital printing substrates, carbon fabrics for high-performance composites, filter media, flame retardant barrier fabrics and heavy-duty membranes are now being coated on Monforts texCoat ranges and finished with the company’s industry-leading Montex stenters.

“Since we acquired the technology that our coating units are based on in 2015, we have made a lot of refinements,” says Hans. “All of these developments are reflected in higher coating accuracy and the resulting quality of the treated fabrics. At the same time, our latest multi-functional coating heads offer an unprecedented range of options, with a wide range of modules available.”

The texCoat user interface is now equipped with the unique Monforts visualisation system and the magnetic doctor blade has greater power reserves. Options include a carbon fibre-reinforced composite coating drum with a more scratch-resistant surface and maximum rigidity and remote control which simplifies exact adjustment for the operator.

Montex stenters in special executions are meanwhile ideal for the drying and finishing of both technical woven fabrics and nonwovens and characterised by high stretching devices in both length and width.

“The European-built Montex range of stenters has earned its leading position in the technical textiles market due to the overall robustness, reliability and economy of these machines,” Hans concludes. “Whatever the intended end-product – and we continue to discover potentially new areas in which technical textiles can be utilised all the time – we have the machine specification and know-how to turn ideas into reality. In India we also benefit from the strong sales and service support of A.T.E. Enterprises.”
