melt spinning of polymer fibers

Melt spinning is the most common and productive industrial process for producing polymeric fibers. Since production disruption and the resulting loss of quality are undesirable in this branch, research is an important element in the further development of the process. In industrial practice, an enormous extraction ratio is often used to achieve the most efficient production possible. These trigger ratios often cause, starting at a critical speed, instabilities that can lead to thread breakage.

The LSP in Erlangen has to examine the melt spinning process, as well as the instabilities mentioned a melt spinning plant and a meltblown line, both of which are designed on a laboratory scale. As a result, changes in production parameters can be varied inexpensively and effectively. The findings can then be transferred to industrial plants to increase the productivity of fiber spinning plants.
