dissolving the aromatic polyamide monomers into the mixed solvent, composed of the individual or mixed solvent of urea or amide and the individual inorganic salt or its mixed solution of Lewis acid compd.; polymerizing to obtain prepolymer prior to gelation, whose intrinsic viscosity (ηinh) is 1.0-5.5; spinning the prepolymer into water, tert-amine or the basic coagulation solution under the state of optical anisotropic liq. crystal condition to obtain p- oriented aromatic polyamide polymer; crushing the polymer in a wet state into the short fibers containing water, in which the content of the fiber is above 50 wt.%; steeping the fiber into a soln. of above 80 deg.C containing dyes and pigments.
