Learning outcomes
|
The aim of the course is to find and understand the relationship between the properties, materials and structure of nonwovens. Knowledge of the relationship structure and material properties of nonwovens is necessary to develop new products, but also helps in the design of new testing methods. Course contents can be divided into 7 chapters.
Experience with structure, wetting and mechanical behaviour of nonwovens.
