Beschreibung
Zusammenfassung:	PURPOSE:To obtain the subject fiber, consisting of a special two component- based multicore-sheath structure having a polyester polymer as a core component and a polyolefin polymer as a sheath component and capable of efficiently providing heat-fusible conjugate fiber of a fine denier by splitting and converting the fiber into fine fibers. CONSTITUTION:The objective fiber which is a conjugate fiber of a multicore- sheath structure consisting of two components and the respective units of plural cores-sheath structural units in which the core part component is a polyester polymer 1 and the sheath part component is a polyolefin polymer 2 are joined through a joining component consisting of the polyester polymer 1. The above- mentioned fiber is obtained by, e.g. joining the core part component from a polymer reservoir 4 to the sheath part component from polymer reservoirs 5 in constricted passages between the first front plate 6 and the second front plate 12 and joining the resultant primary core-sheath conjugate stream to the joining component passing from the polymer reservoir 4 through polymer reservoirs 14 and 16 is constricted passages between the second front plate 12 and a spinneret 17 and then discharging the obtained stream through discharging holes 19.
