Abstract

The invention pertains to a method for obtaining a PPTA yarn with increased compressive strength by the steps of air gap spinning a PPTA spin dope to PPTA filaments, bundling the filaments to the yarn, washing and optionally neutralizing and drying the yarn, characterized in that these steps are followed by applying a heat treatment to the PPTA yarn comprising heating the yarn at a temperature of 340 to 510 ºC for 5 sec to 5 min under exclusion of oxygen. The invention further relates to a PPTA yarn thus obtained having filaments with an average compressive strength à c of at least 0.8 + 2.5*10 -3 *(E-100) GPa, wherein E is the modulus in GPa.
