Booth 2657
The trade fair INDEX in Geneva is an international trade fair for nonwovens. About 580 exhibitors will present their latest products and services at the fair. We will be on site with a team from the department »Transport Processes« and present our expertise and research on technical textiles and nonwovens. Visit us at booth 2657!
Our department »Transport Processes« researches already for many years in the field of technical textiles and nonwovens. Our created tools simulate fluid and fiber dynamics in spinning and laydown part of fiber and nonwoven production. We offer simulation tools in the filed of filtration and virtual material design together with quality control by surface inspection and image processing. This supports the development and exploration of new technologies and helps to improve quality in the whole process chain up to product properties.
Registration for the four-day event is via the official event website: online registration

Hybrid machine learning in textile mechanical engineering
Machine learning is currently experiencing an enormous boost. A disadvantage of machine learning is that huge amounts of data are required to train the models. In particular in special purpose machinery manufacturing the number of available data sets is limited. In this talk we present the so-called hybrid machine learning concept, an approach to extend experimental data by simulation-generated data in order to solve the missing data problem.

Virtual Optimization of Fiber Processes with FIDYST
The Fiber Dynamics Simulation Tool (FIDYST) is an efficient software to simulate the dynamic behavior of elastic fibers in turbulent flows. Its companion tool SURRO allows to quickly generate virtual micro-structures based on the physical simulations. Processes like Spunbond and Airlay can be simulated and optimized with regard to improved process parameters and resulting product quality.

Modeling and Simulation of Crystallization in Spinning Processes
Spinning processes are important industrial processes with applications ranging from staple fibers and nonwovens to indutrial textiles. Concerning the fiber quality the spinning process is a crucial step in the production chain. Especially the degree of crystallisation influences the quality of fibers. Fraunhofer ITWM has developed suitable methods to simulate such a complex process. A weak iterative coupling algorithm based on the combination of commercial software and self-implemented code makes the simulation of the industrial spinning processes possible. A parameter study shows the influence of diffrent process an drunning conditions on the degree of crystalisation.

Physical modeling and simulation of fine fiber generation in meltblown processes
Spinning in meltblown processes leads to finer diameters down to submicron or nano fibers due to turbulent acceleration steps. We have developed a physical model of the filament dynamics according to the corresponding air fluctuations. By simulation the meltblown process is shown to be a combination of uniaxial-stretching near to the nozzle with high air speed and further acceleration by stochastic forces caused from turbulent air fluctuations.
