POLYAMIDE CONJUGATED FIBERT AND THAT'S PROCESS MANUFACTURE

摘要

An wholy aromatic polyamide is prepd. by the steps. of: preparing an optical isotropic prepolymer and an optical anisotropic prepolymer of different polymer ratio w.r.t. solvent, of 1.0-4.0 inherent viscosity by polymerizing aromatic diamine and aromatic diacid chloride in the mixt. of amide based solvent and inorg. salts as inssolving agcnt; extruding-complex spinning through the same spinning nozzle with molecular polymn. solvent the two-prepolymer in order to conjugate continuously the filaments of two-prepolymer in direction of length.
