Abstract

PURPOSE: To obtain the titled fibrous bundled aggregate having a cross section resembling that of the silk and a high polymerization degree, by reacting an aromatic polyester with a biscyclic imino ethereal compound, and spinning the resultant material having a high polymerization degree through a specific spinneret.
CONSTITUTION: A fiber-forming aromatic polyester, consisting of an aromatic dicarboxylic acid having terminal carboxyl groups as a principal acid component is reacted with a biscyclic imino ethereal compound of the formula (X1 and X2 are bifunctional hydrocarbon groups, having 2 or 3 ring member carbon atoms forming an imino ethereal ring, and unreactive under the reaction conditions; R1 and R2 are H or monofunctional hydrocarbon groups or together link to form a five- or six -membered ring with two N atoms and D group; D is unreactive bifunctional hydrocarbon group which may contain a hetero-atom; n is 0 or 1) at a high temperature, and the resultant material having a high polymerization degree is molten and spun through a spinneret having discontinuous protrusions between the fine adjacent gaps on the extruding side.
