Summary: | A process for manufacturing an aramid pulp including polyvinyl pyrrolidone (PVP), the method including 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 including PVP. It has been found that the process makes it possible to obtain a PVP pulp with improved dewatering properties and energy consumption in combination with a high PVP retention. |
