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 customized to specific production requirements. bematic® bring their expertise in development and construction of nonwoven production lines to the project and will manufacture the new air-lay systems developed through the joint project.

Swiss-based Siriotek specialize 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 advance and optimize 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 optimization, as well as know-how in mathematical modeling and characterization of air-lay processes for staple fibers.

The three partners aim to jointly develop the next generation of air-lay machines to ensure performance and quality in processing with staple fibers 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

Air-lay technologies provide thermal, mechanical and chemical web bonding. In this process, the raw material is opened and introduced into an air stream by a roller. This air-fiber mixture lands on a belt where it is compacted by suction. "Through a collaborative approach, we are pushing the boundaries of air-lay technology to achieve higher production speeds, better nonwoven uniformity and fiber utilization, and ultimately deliver solutions that are fully tailored to individual production requirements," explains Giovanni Di Lorenzo, founder and chief engineer of Siriotek.
