Abstract
A method for producing para-aramid pulp by using gravity-induced orientation of anisotropic para-aramid solutions. The solutions are those in which the para-aramid is still actively polymerizing. The process can be practiced on immobile inclined supports or on a moving inclined support in the form of a conveyer.
