The present invention relates to a dental cord using a nanofiber composite yarn capable of effectively impregnating a drug such as a hemostatic agent using a nanofiber composite yarn having a large specific surface area and having three-dimensional pores, and a method for producing the same. The dental cord of the present invention comprises a nanofiber composite yarn in which at least two nanofiber tape yarns are composed of a composite yarn and a twisted yarn impregnated with a drug, the nanofiber tape yarn is made of a fiber-forming polymeric material, Wherein the nanofibers are formed of a nanofiber web having three-dimensional micropores. |
