Spinning polymer filaments, for example for personal care articles, is highly complex: simulating the processes involved is too much for currently available computing power to handle. Fraunhofer researchers have successfully applied new approaches to simplify the calculations necessary for simulation. Now for the first time complete spinning processes can be simulated, providing a better understanding of the processes and greatly simplifying their optimization.
