From the Sector

The EU's planned ban on the entire group of per- and polyfluoroalkyl substances (PFAS) would endanger many industrial processes, states VDMA Textile Machinery. Textile manufacturing would be affected twice – by missing important chemicals for technical textile production and by the lack of indispensable textile machine components. The latter would affect the whole supply chain from textile machinery manufacturers and its suppliers to the textile industry in the EU.

Solid PFAS parts are widely used in textile machinery production, especially where extreme conditions prevail. Verena Thies, Managing Shareholder Thies GmbH & Co. KG, explains: “Our textile dyeing machines are world leaders and set standards in efficiency and sustainability. They work under pressure at temperatures of up to 140° C using highly acidic, highly basic and/or oxidative or even reductive chemicals. This is precisely why PFAS is needed, for example, in seals and rings, flaps as well as valves for a long-lasting and high-quality machine concept – because there are no alternatives with qualitatively equivalent properties. In addition, PTFE semi-finished products enable a sliding and gentle contact with the textile fabric in ecologically important techniques in the transformation of textile wet finishing."

PTFE and also FKM are fluoropolymers (fluoroplastics and fluoroelastomers), a group within the broad PFAS range of about 10,000 substances which would be banned for production, use and sale in the EU. They are high-tech materials, and as so-called "polymers of low concern" are not a danger to the environment, according to the OECD. Furthermore, these components are installed inside a machine and exchanged or disposed of properly. PFAS such as PTFE and FKM must be exempted from the ban, demands the VDMA in its position paper.

"In this way, the association also supports the approach taken in Great Britain. With the 10,000 substances, everything is lumped together, although the various PFAS groups are very different," warns Dr Sarah Brückner, Head of VDMA Environmental Affairs and Sustainability. "We should take our cue from the UK and look at the substance groups in a differentiated way."
Apart from several types of dyeing machines, PFAS components are indispensable in textile drying machines (e.g., conveyor dryers, tumblers and stenters) and damping machines. They are also used in fully automatic chemical dispensing systems and pressure vessels for thermochemical treatment of textile recycling material, heat recovery systems and wastewater treatment technology. This means that a lot of machines needed for a sustainable textile production would be affected by the PFAS ban.

VDMA Textile Machinery will take part in the ongoing EU public consultation. The association will describe indispensable key functionalities and conditions of use in the textile machinery sector as well as the consequences for the companies and the customers in the EU if the ban is imposed. The consultation ends on September 25, 2023, and VDMA urged its members affected by the planned restriction to participate in the consultation at an early stage. This is the only way to ensure that the broad scope of the mechanical and plant engineering sector is represented.

International technology group ANDRITZ has received an order from Yanpai Filtration Technology Co., Ltd. (YANPAI®), China, to supply batt forming equipment with an aXcess card and crosslapper for a needlepunch line producing PTFE filtration products at its site in Tiantai. The PTFE felts will be used as smoke filters in waste incineration plants. Start-up of the line is planned for the second half of 2022.

Yanpai is one of the leading Chinese producers of nonwoven filters for dust and air treatment and of woven filter fabrics used in solid/liquid separation. Established in 1990, Yanpai was at the forefront of development work on new industrial filtration fabrics. Today, Yanpai is a company with facilities in China and the USA.

• SGL Carbon supplies first plants with DIN EN1591-1 tightness certification to the chemical industry
• First column already delivered to major European customer

In plant operation in the chemical industry, the tightness of flanged joints is becoming increasingly important when dealing with aggressive and corrosive operating media. In accordance with European Union requirements, the German government has defined new requirements in the first administrative regulation to the Federal Immission Control Act (BImSchG), which will apply from January 2021. SGL Carbon is the first manufacturer of PTFE-lined columns to be able to provide the required proof of tightness according to DIN EN 1591-1 and has already delivered the first column with the new certification to a major European customer.

Specifically, the Technical Instructions on Air Quality Control (TA-Luft) of the Federal Immission Control Act (BImSchG) prescribe new, stricter emission values (leakage class L0.01) for keeping the air clean, which must be complied with when operating plants requiring a permit. In order to be able to guarantee the technical tightness of steel/PTFE flanged joints, SGL Carbon, together with a working group of other companies, first determined the EN 13555 sealing characteristic values, which reflect the material-specific PTFE properties as well as the characteristic manufacture and shaping of the linings. With these characteristic values integrated in a database, SGL experts were able to perform realistic DIN EN 1591-1 calculations for flanged joints of a packed column lined with POLYFLURON PTFE and prove the tightness in accordance with TA-Luft. The design, final acceptance and pressure tests in accordance with Directive 2014/68/EU (PED) were successfully certified by a recognized notified body.

"With the rapid implementation of the new  tightness requirements for columns, our solutions offer customers further significant added value, which is currently also being applied to other products. Our sales team and technical service are available to provide customers with comprehensive advice on the new directives and our products," explains Ralph Spuller, Director Product Management in the Process Technology (PT) Business Unit at SGL Carbon.

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. The fair offers products and technologies for 12 application areas* which cover the entire industry.

Buildtech benefits from Belt & Road and other infrastructure investment

With a huge boom in national and regional infrastructure projects, the market for Buildtech products, especially geotextiles and construction textiles, is rapidly expanding. In particular, the government’s global Belt & Road project, as well as continued investment at home in highways, high-speed rail and more, is fuelling this expansion. According to CNITA, in 2017 China started 35 new railway projects, with additional private capital investment in this sector totalling some USD 53 billion that year. The same investment in highway construction increased 17.7%, while water conservation project investment by private firms reached a new record of USD 105 billion.

With this potential in the Asian market, it’s no surprise a number of new exhibitors will feature in the Buildtech sector at the fair, including FPC Technical Textile from Saudi Arabia, Kobe-cz from the Czech Republic, as well as Lenzing Plastics, while Johns Manville are one of the returning exhibitors this year.

• FPC Technical Textile (Saudi Arabia) produce high-end specialty fabrics including PVC coated fabrics and fibre glass PTFE fabrics, and will focus on the latter at the fair.

Mobiltech benefits from huge increases in automobile production in China

With new textile innovations and application possibilities spreading throughout the automobile industry, coupled with the fact China is the world’s largest auto producer, Cinte Techtextil is the place to see the latest products and technologies for this sector this September. Automobile production in China reached 29 million units in 2017, an increase of 3% year-on-year. Staggeringly, new-energy vehicle production grew by 53% last year, while SUVs and commercial vehicles increased 13.81% and 13.95% respectively.

With such strong growth in China, a number of leading international Mobiltech producers, as well as top domestic suppliers, will be at Cinte Techtextil this year, including:

• Abifor (Switzerland): their focus at the fair is on products designed for automotive, construction and other technical applications, in particular their specialty hot-melt powders.

Exhibitors from eight countries have already confirmed to participate in the fair’s European Zone. They join an expected 500-plus total exhibitors from around the world. The 2018 edition of this biennial fair takes place from 4 – 6 September in halls N1 – N3 of the Shanghai New International Expo Centre.

While China retains its edge in terms of technical textiles and nonwovens production capabilities, in the eyes of Chinese buyers, European suppliers are still the leaders when it comes to technology and innovation. This was widely reported by European exhibitors at the previous edition in 2016 of Asia’s leading biennial trade event for the industry: Cinte Techtextil China.

“In the Chinese market, buyers want good quality products, so overseas companies, and products with recognised quality certifications, have a lot of potential,” Ms Ping Chen, General Manager of IBENA Shanghai Technical Textiles commented. “As a leading German company in the industry, our products are welcomed by many buyers at this fair. It is also important to be in the German Pavilion as this signals to buyers that we have quality products, and it attracts more attention.” Swiss firm Sanitized AG had the same experience. “As a Swiss company in the European Zone I believe it’s an advantage, as some local buyers have more confidence towards imported products,” Mr Steven Liu, Sales Manager said.

Other exhibitors commented on the long-term trends in the Chinese market. “There’s a definite shift to more high-quality machinery in China that isn’t affected by what’s happening in the overall economy. Moreover, there are opportunities for overseas suppliers as there is still a gap between us and what Chinese companies produce,” Dr Joachim Binnig, Vice President, Head of Development & Technology, Autefa Solutions Germany GmbH explained.

Mr Roger Zhang, Sales Manager for German firm J.H. Ziegler Nonwovens and New Materials commented: “Our products are mainly for high-end Chinese customers, such as BMW and Audi. The Chinese market has gradually matured, but the production capability for high-performance products which are energy efficient and eco-friendly is still developing, so there is a lot of space for overseas brands to develop here.”
