The present invention relates to a core-sheath type polyester conjugate fiber and a process for producing the same. More specifically, the present invention relates to a core-sheath type polyester conjugate fiber which is hydrolyzed due to structural weakness of a flame retardant, The present invention relates to a polyester composite fiber in which flame retardant components and flame retardant components are introduced into the core and the sheath, respectively, in order to prevent detachment of the flame retardant component. |
