Title:
MANUFACTURING METHOD OF STRETCHED BODY MADE OF POLYOXYMETHYLENE RESIN
Document Type and Number:
Japanese Patent JP2008230086
Kind Code:
A
Abstract:
To provide a method which enables the continuous manufacture of a polyoxymethylene resin-made stretched body and a polyoxymethylene resin-made stretched body having high rigidity and high strengths.
In the method of continuously manufacturing the polyoxymethylene resin-made stretched body by plasticizing a polyoxymethylene resin, spinning from an extruder die into a rod-like or filamentous molded body, cooling in a cooling bath and conducting the heating and stretch in a stretching bath, the method is characterized by cooling stepwise using two cooling baths.
