We encounter products made from polypropylene fibers and nonwovens in a number of different areas of our daily life, like in hygiene products or filter systems. During their production, parameters like the haul-off speed of the fiber, the processing temperature or the residence time have an impact on the physical properties like the (surface) crystallinity or the molecular weight and the mechanical properties like the Young’s modulus or the stress at break. The complexity of industrial facilities for the production of nonwovens does not allow to change parameters quickly and independently. Therefore, it is hardly possible to reveal the influence of individual processing parameters and systematically build knowledge about these. A pilot spunbond line developed at the institute of polymer materials allows to separate single process steps in order to show the influence of different spinning parameters on the properties of the single fibers and nonwovens. Even though studies exist which look into heat treatments of fibers, degradation of polypropylene in dependence of residence time and temperature or mechanical properties as a function of processing conditions, no studies exist which cover the influence of industrially relevant storing (time and temperature) and processing conditions (haul-off speeds, calendering settings and process temperatures) of fibers and nonwovens in their entirety. This study gives a comprehensive overview over the influence of mentioned spinning parameters on mechanical properties, degradation behavior and surface crystallinity of the products.
