Abstract
A spinneret device for side-by-side, conjugate melt-blow spinning 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 has fineness, a large nozzle plate width and a superior productivity. The device is composed mainly of a spinning resin-feeding plate; a distributing plate; a separating plate provided with confluent grooves of conjugate components engraved at the bottom part of the plate, corresponding in number to the spinning nozzles; a nozzle plate; and a plate for controlling the clearance for a gas. Even when the viscosity unevenness, spinning temperature unevenness, etc. of the spinning resins occur in the cavity of the nozzle plate to some extent, microfine fibers can be obtained which are uniform in the composite ratio and the cross-sectional, peripheral percentages of the respective components in the fiber cross-section, while being uniformly fine.
