Summary:PURPOSE:To provide a polybenzazole fiber having a color tone suitable for a clothing-like product and a textile fabric composed mainly of this fiber. CONSTITUTION:The polybenzazole fiber is dyed till the middle part in its cross- section and has >=4.0GPa strength and >=140GPa initial elasticity modulus. As the polybenzazole, e.g. polybenzooxazole (PBO) homopolymer, polybenzothiazole(PBT) homopolymer and a random, sequential and block copolymer between PBO and PBT are exemplified. As the pigment, e.g. an organic pigment such as pigment yellow 12, pigment yellow 13, pigment orange 16, pigment blue 7 or pigment blue 15 or an oil-soluble dye such as solvent green 28 or solvent green 13 is used. A textile fabric is produced by using the above- mentioned polybenzazole fiber as the main component.
