From the Sector

Fibre Extrusion Technology of Leeds, UK has delivered nine meltspinning systems to clients in the biomedical sector since the onset of the Covid-19 pandemic, with a similar number currently on order for 2021/22. This way FET could confirm the position as an acknowledged world leader in meltspinning equipment for the production of precursor materials used in medical devices and as a default supplier for absorbable suture production systems, with orders virtually doubling year on year.

Recent installations include a multi-functional system that can produce both multifilament and monofilament pre-cursor fibres, but nonwoven systems have been particularly prominent, driven by the burgeoning demand for FFP3 masks, gowns and other medical products required during the pandemic. These have been sold to medical device manufacturing companies across the globe, including the Far East, USA and Europe. Research organisations have also invested in FET systems for biomedical applications, the most recent being the University of Leeds in a laboratory scale Spunbond system.

The FET in-house Process Development Laboratory and ongoing collaboration with biomaterial polymer suppliers has helped to optimise the biomedical melt spinning technology. The Laboratory is at the disposal of customers for all aspects of confidential testing and evaluation. To further increase this competitive edge, FET will be opening a new Process Development Laboratory and Visitor Centre in early 2022.

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.

Fibre Extrusion Technology Ltd of Leeds, UK has installed a new meltspinning system to upgrade research facilities at NIRI, the Nonwovens Innovation & Research Institute Ltd UK, a global leader in nonwoven engineering and product development.

Established in 1998, FET is a leading supplier of laboratory and pilot meltspinning systems with installations in over 35 countries and has now successfully processed almost 30 different polymer types in multifilament, monofilament and nonwoven formats.
 
The installation comprises a FET-102 Series Laboratory Meltblown Spinning System and FET-103 Monofilament Meltspinning System. This advanced equipment enhances NIRI’s extensive pilot facilities and state-of-the-art analytical laboratory for fast tracking innovation. In particular, the FET meltblown system will be utilised for R&D, pilot projects, sampling and prototyping, proof of concept testing and for designing cost-effective, sustainable and innovative products.

NIRI supports global manufacturing companies to identify new opportunities for meltblown nonwovens, develop their next generation of products and accelerate their commercialisation activities. NIRI’s new upgraded laboratory and pilot system from FET can process a wide range of polymer types, including chemically recycled polymers, bio-polymers and many difficult-to-process materials.

• Order intake of CHF 975.3 million (first half of 2020: CHF 250.7 million).
• Sales of CHF 400.5 million (first half of 2020: CHF 254.9 million).
• EBIT of CHF 9.0 million and net profit of CHF 5.3 million

The first half of 2021 has been characterized by a strong market recovery in combination with a regional shift in demand for new machinery and systems. Rieter anticipates a normalization of the demand for new systems in the coming months. The company assumes that spinning mills will continue to work at high-capacity levels.

For the full year, Rieter expects sales to be above CHF 900 million.

The realization of sales from the order backlog continues to be associated with risks in light of bottlenecks in material deliveries and freight capacities as well as the ongoing pandemic in key markets for Rieter.

In recent years, Rieter has implemented its strategy based on the cornerstones of innovation leadership, strengthening the components, spare parts and services businesses, and adjusting cost structures.

Crisis management in the pandemic year of 2020 was aimed at protecting employees, fulfilling customer commitments, ensuring liquidity, and also strengthening the market position for the time after the pandemic as well as retaining the ability to benefit from the incipient market recovery.

The focus for 2021 remains on the implementation of this strategy. The measures for crisis management relating to the protection of employees and fulfilling customer commitments are still in effect in countries that continue to be affected by the pandemic.

The Rieter Board of Directors has approved the implementation of the CAMPUS project. The Rieter CAMPUS comprises a customer and technology center as well as an administration building at the Winterthur location. It will make an important contribution to the implementation of the innovation strategy and to the enhancement of Rieter’s technology leadership position.
