Method of manufacturing a dental cord
Provided is a method of manufacturing a dental cord. The method including: producing a spinning solution by dissolving a fiber-moldable hydrophobic polymer material in a solvent; spinning the spinning solution to obtain a polymer nanofiber web composed of nanofibers and including three-dimensional micropores; laminating the polymer nanofiber web to obtain a polymer membrane; slitting the polymer membrane to obtain a nanofiber tape yarn; hydrophilic-treating the nanofiber tape yarn to obtain a hydrophilic-treated nanofiber tape yarn; plying and twisting the hydrophilic-treated nanofiber tape yarn with a covered yarn to obtain a nanofiber multiple yarn; and impregnating the nanofiber multiple yarn with a hemostatic agent.
