Spinnvorrichtung für Schmelzblasspinnen von Verbundfäden

摘要

A spinneret device for side-by-side, conjugate melt-blow spinning is provided, which device can correspond to combinations of various heterogeneous polymers for conjugate spinning and is uniform in the conjugate state such as conjugate ratio between single fibers, the proportion of the peripheral percentage of both the components in the fiber cross-section, etc. and is small in the fineness unevenness as well as it has a large width of nozzle plate and a superior productivity, and which device is composed mainly of a spinning resins-feeding plate 2; a distributing plate 3; a separating plate 4 provided with confluent groove 12 of conjugate components engraved at the bottom part of the plate 4, provided corresponding to the number of spinning nozzles; a nozzle plate 5; and a plate 6 for controlling the clearance for a gas, and according to which device, even when the viscosity unevenness, spinning temperature unevenness, etc. of the spinning resins occur in the cavity of the nozzle plate 5 to some extent, microfine fiber can be obtained which is uniform in the composite ratio and the cross-sectional, peripheral percentages of the respective components in the fiber cross-section, and yet being small in the fineness unevenness.
