Fibre spinning techniques Extrusion

Fibre spinning techniques were primarily developed for the production of meat analogues. Unfortunately, their technical success did not result in cost competitive products and most of this type of extrusion processing has been shelved. 

Often, the development of good quality LCP fibrils by melt processing techniques such as extrusion and injection moulding was difficult because the fibrillation conditions were not as favorable as those in an optimized spinning process. The results obtained was interesting as this method of preparing in-situ composites was able to achieve high aspect ratio LCP fibrils especially in PP/PET-PHB systems where poor fibrillation was observed even with spun fibres (Landel and Nielsen 1993).
