The big advantage: the threads are anchored in the nonwoven fabric with the help of ultrasound alone, without any additional joining agents. Compared to the conventional gluing process, this significantly reduces the consumption of resources and energy and thus the overall manufacturing costs. The feel and sustainability balance of the products also improves enormously.

The particularly fine surface geometry and the gentle process also ensure that the risk of thread breakage has been minimised and that different material combinations can be implemented on a single sonotrode.
