Fraunhofer ITWM, Siriotek and bematic® join forces to advance nonwovens production technology

Nonwoven fabrics play today a central role in a number of industries, including automotive, healthcare, medical, construction, and filtration. As demand for these versatile materials continues to grow, Bettarini & Serafini S.r.l (trading as bematic®), Siriotek GmbH and the Fraunhofer Institute for Industrial Mathematics ITWM are now joining forces to enhance and develop air-lay technology for production of nonwovens. The joint project will be presented for the first time at ITMA 2023, the trade fair for textiles technology, materials and innovation.

Based in Italy, bematic® have been developing and manufacturing nonwoven production lines for almost 50 years and today their carding machines are in daily use across the world. The company provides turnkey solutions customised to specific production requirements. bematic® bring to the project their expertise in development and construction of nonwoven production lines and will manufacture the new air-lay systems developed through the joint project.         

Swiss-based Siriotek specialise in mechanical engineering and product development through practical application of virtual prototyping and testing. Throughout the project Siriotek engineers will use analysis, modelling and simulation to drive and optimise the design layout of the new air-lay system.         

Fraunhofer ITWM, in turn, contributes to the project with both knowledge and experience in the textile technology and process optimisation, as well as know-how in mathematical modelling and characterization of air-lay processes for staple fibres.

Combining expertise

The three partners aim to jointly develop the next generation of air-lay machines to ensure performance and quality in processing with staple fibres whilst reducing energy consumption, waste generation and carbon emissions. The collaboration brings together the expertise and innovation capabilities of three specialist players in their respective fields.

Faster, denser, more efficient

In air-lay processes raw fibres (natural or synthetic) are opened up and apart by a card roller, introduced into a forced air stream and directed onto conveyor belts. The randomly arranged fibres are then compacted by suction and finally bonded together through mechanical, thermal or chemical processes to achieve web consistency. “Through a collaborative approach, we are pushing the boundaries of air-lay technology to achieve higher production speeds, improved nonwoven uniformity and fibre utilization, and ultimately deliver solutions that are fully tailored to individual production requirements,” explains Giovanni Di Lorenzo, Founder and Chief Engineer at Siriotek.

Improved efficiency and sustainability

The project also aims to minimise energy consumption and environmental footprint without compromising performance. “We are driving progress, improving production quality, and contributing to a more sustainable as well as efficient ecosystem in the textile industry” says Dietmar Hietel, Head of the Transport Processes Department at Fraunhofer ITWM.

Giovanni Bettarini, Partner and Commercial director at bematic® adds: “Through this collaboration we will be able to offer more efficient and sustainable manufacturing solutions, tailored to specific applications across automotive, construction, filtration and geotextile”

From June 8 to 14, 2023, the project team will welcome industry representatives to their booth in Hall 10-A101 at ITMA in Milan to share details of the project.
