Abstract

A dyeable polyparaphenylene terephthalamide fiber which has been wound once after spinning and has not be dyed yet, characterized in that it has a tensile strength of 15 g/denier or more and a crystal size (110 direction) of 30 to 55 angstroms and has been dried to have a water content of 8% or less, and in that it has no history of treatment, and a method for producing the same. A polyparaphenylene terephthalamide fiber which has capability of being dyed without detriment to excellent inherent properties of high strength and high modulus elasticity, and textile products made of the fiber which are dyed in a variety of colors can be provided.
