PURPOSE: A process of preparing artificial thread by polymerization-coating treatment of a low-density thermoplastic resin drawn yarn on a high-density thermoplastic resin drawn yarn firstly prepared through an extrusion, drawing process or the like and changing the shape of a nozzle is provided which produces artificial thread creating a texture and shape like natural fiber. CONSTITUTION: The preparing process of artificial thread comprises: a first forming process consisting of extruding raw material at 180 to 200deg.C, forming a fine S-shaped concavo-convex surface on a cylindrical film, slitting the two-fold films into several stripes, drawing at a drawing ratio of 6 to 8:1 and annealing; and a second forming process consisting of melt-forming raw yarn through a first nozzle at 110 to 130deg.C and a second nozzle at 190 to 230deg.C, cooling using a water tank, drawing and winding. The nozzle has a variety of shapes such as a round, ellipsoid or polygon. |
