摘要

Method of preparing monofilaments consisting predominantly of highly crystalline polypropylene, characterized in that it is extruded by adjusting the inlet temperature to the extruder at 20-100ºC higher than the melting point of the polypropylene, decreasing said temperature along the extruder so that in the head extruder is from 0 to 40ºC higher than said melting point.
