Abstract (en)
A spinneret assembly for spinning multi-ingredient composite fibers, each of which has a large number of core ingredients finely dispersed in an intervening ingredient, includes at least three kinds of elements W, X and Z. A first element W has at least a composite stream forming region 10 in which two separately guided polymer streams I and II are joined, and channels (4, 5, 7) and (9) respectively for the two polymer streams I and II. A second element X has a stationary type dividing device II. A third element Z has a converging portion 12 and a nozzle orifice 13 discharging the resultant composite stream to form a multi-ingredient composite fiber. From the fibers thus produced, extremely fine filaments are obtained by dissolving the ingredients other than core ingredients,
