Abstract

PURPOSE: The title fibers having improved initial modulus, consisting of a polymer obtained by adding a specific amount of an aromatic ring-containing amino-carboxylic acid (derivative) to a polyester in the early stage of melt polycondensation.
CONSTITUTION: 2W30wt% of an amino-carboxylic acid (derivative), e.g. p-amino- benzoic acid, or 4-amino-4'-carboxybiphenyl, having a highly rigid aromatic ring is added to polyethylene terephthalate or a polyester consisting mainly of it in the early stage of melt polycondensation. Preferably, 0.01W5wt% of a phenol heat stabilizer, e.g. diphenyl (4-hydroxy-3,5-di-tert-butylpheylmethyl)phosphonate, is further added to the polymer to give the objective fibers.
