The invention pertains to a process for manufacturing an aramid pulp comprising polyvinyl pyrrolidone (PVP)， the method comprising the steps of - combining para-aramid short-cut with PVP in an aqueous solution to form a mixture， - subjecting the mixture to a refining step to form a para-aramid pulp comprising PVP. It has been found that the process according to the invention makes it possible to obtain a PVP pulp with improved dewatering properties and energy consumption in combination with a high PVP retention.
