PURPOSE:To provide a high-tenacity aromatic polyamide fiber having light resistance improved by the ultraviolet-reflecting, shielding, and absorbing actions of inorganic particles having a high refractive index. CONSTITUTION:The objective aromatic polyamide fiber having a single fiber fineness of 0.5-50de and mechanical properties satisfying the following conditions contains (at least in the surface layer of the fiber) 0.1-5wt.% (based on the fiber) of inorganic particles having refractive index of >=2.0 and an average particle diameter of <=0.3mum. Strength, >=18g/de; elongation, >=3.5%; initial modulus, >=450g/de. |
