Overview processes and technical equipment
The Centre of Excellence in Nonwovens brings together all nonwoven formation and consolidation processes in the technology areas of fibre nonwovens and spunbond nonwovens. Fibres of any origin and staple length can be formed into a web in our pilot plants. Our extensive know-how and the targeted pooling of expertise with other departments are key guarantees for the successful execution of research and development work. We operate on both a small-scale and semi-industrial scale.
