METHOD FOR PRODUCING ANTISTATIC POLYPROPYLENE FIBER WITH IMPROVED MECHANICAL PROPERTIES

摘要

1. A method of obtaining an antistatic polypropylene fiber with improved mechanical properties, including the stage of mixing in the extruder melt polypropylene and carbon nanotubes in an amount of 1-3 wt.% And extruding the fiber from this mixture, characterized in that the fiber is further subjected to eight-fold orientation drawing, which is carried out in two stages: at a temperature of 150 ° C, at first the fiber is pulled four times, then two more times. 2. A method for producing an antistatic polypropylene fiber according to claim 1, characterized in that single-walled nanotubes are introduced in an amount of 0.7-1% by weight of the polymer. The method for producing an antistatic polypropylene fiber according to claim 1, characterized in that carbon nanofibers are introduced in an amount of 3-5% by weight of the polymer.
