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.

As the world’s largest producer of technical textiles and nonwovens, China’s demand for production machinery is insatiable. As such, this September’s Cinte Techtextil China has attracted some of the world’s leading machinery brands, particularly in the nonwovens and sewing machinery sectors, ensuring a wide range of sourcing options for both domestic and international buyers.

Overseas producers respond to strong Chinese demand
As the Chinese domestic and export markets’ demand for quality technical textiles and nonwovens products continues to increase, overseas machinery brands continue to enter the country, using Cinte Techtextil China as their starting-out platform. ANDRITZ Nonwoven is just one of those who see the growing potential. “Chinese nonwovens manufacturers are increasingly requiring higher capacities and top-class quality for their nonwovens products for local and export markets,” Mr Laurent Jallat explained. “China is the biggest market in terms of installed capacity, and shows quite promising potential for the future. In the past years, we’ve seen rapid growth in products such as disposable face masks.” ANDRITZ responds to this demand with their neXline spunlace eXcelle line which features state-of-the-art TT card web forming and JetlaceEssentiel hydro entanglement units for high capacity and speed.

The DiloGroup also report an increase in demand for their products in China. “China is one of our biggest markets,” explains Mr Dominik Foshag. “We have procured huge orders from China, as Chinese customers are considering German technology more frequently nowadays. The visitor quality of Cinte Techtextil has been very good in this past, and we think this year’s fair will be also successful as we know many of our customers are going to visit.”

Oerlikon will introduce its spunbond technology to the Chinese market this year, and is expecting to conclude initial contracts at the fair due to increased demand for overseas products. “The Chinese market for nonwovens products is by far the largest and fastest growing national market. Chinese manufacturers are no longer satisfied with lower product quality, but want to exceed Western quality levels, for example. The products must now meet stricter customer requirements and legal standards, some of which are significantly higher than other international standards,” Ms Lena Kachelmaier said.

Truetzschler Nonwovens has also noticed this trend. Ms Jutta Stehr commented: “In the last two or three years, China became one of the pacemakers in the field of nonwovens used in beauty, skin care and hygiene applications. Asian markets have set new standards concerning quality in nonwovens. For instance, making disposable wipes from cotton fibres is a trend originating in Asia. The luxurious feeling of cotton combined with the requirement for eco-friendly products will further drive demand in China and elsewhere. Accordingly, Truetzschler Nonwovens anticipates more inquiries at Cinte Techtextil for its proven carding and spunlacing solutions for cotton nonwovens.”

Weaving machine supplier Itema has also noticed strong demand in China for products made in Italy. “Generally speaking, and especially for technical fabrics, imported machinery is highly evaluated and appreciated by Chinese customers. In recent years, Itema experienced significant growth in the sale of its Made-in-Italy weaving machines in China, and in other APAC countries. Imported machines are synonymous with quality and reliability, and we believe this positive trend will be constant in the future,” Mr Matteo De Micheli outlined.
