Abstract

PURPOSE: To obtain the titled fibrous bundled aggregate having cross sections resembling that of silk and the moderate irregularity in the axial direction, by reacting an aromatic polyester with a biscyclic iminoester compound, and spinning the resultant material having a high polymerization degree through a special spinneret.
CONSTITUTION: An aromatic polyester, consisting of an aromatic dicarboxylic acid as a principal acid component and having terminal hydroxyl groups is reacted with a biscyclic imino ester compound of formulaI(Y is bifunctional hydrocarbon group which may have a hetero-atom; X is unreactive bifunctional hydrocarbon group which may have 1 or 2 ring member carbon atoms forming the imino ester group; l is 0 or 1) or formula II[A is formula III or IV (R2 is monofunctional hydrocarbon group); R is tetrafunctional aromatic group which may have a hetero-atom; R1 is monofunctional hydrocarbon group]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 adjacent fine gaps on the extruding side.
