Melt spinning tests can be carried out at the DITF with gram quantities of polymers (Minilab Extruder) as well as on large spinning lines on an industrial scale.
An extensive repertoire of technologies is available to investigate the spinability of the melts, the properties of the yarns produced and the structure formation in the yarn. For example, spinability can be analyzed under the influence of various additives such as flow improvers.
Depending on the results of the investigations, different technologies are used, e.g. to adapt the chemical-physical properties of the polymer melt or the chemical-physical conditions during yarn formation.
