PURPOSE: A manufacturing method of aramid multifilament is provided to offer good post-processing property with low powder scattering attached on a roller by forming air interlacing points. CONSTITUTION: A manufacturing method of aramid multifilament includes the following steps of: spinning aramid dope through a spinneret(40); passing the dope through a non-coagulated fluid layer; solidifying the dope; rinsing the dope; drying the dope; air-interlacing the aramid dope with an air interlacing machine; and producing the aramid multifilament wound. The dried multifilament is air-interlaced with the pneumatic pressure of 1~3 kgf / cm^2. |
