摘要： Multi-segment filaments can be obtained by feeding a flow of liquid spinning material composed of at least two thin layers, which extend radially from the center portion of the crosssection of a conduit towards the peripheral wall of the conduit so as to reach the peripheral wall, into the conduit from the upper end thereof, and at the same time feeding forcedly a flow of another spinning material into each of small sections between the above radial thin layers and the periphery wall of the conduit to put the above described thin layers between the flows of the latter spinning material, and then extruding the joined flow through the orifice, by the use of spinneret having a simple structure. There are two types of arrangements of the conduit, feed nozzle and duct, in one of which the thin layer forming spinning material is fed from the feed nozzle to the conduit, and in another of which the thin layer forming spinning material is fed from the duct into the conduit.
