<p>A spinneret device for spinning conjugate fibres of eccentric sheath-and-core type which device comprises a cap (1) having inlet holes (2A,2) for introducing a sheath component stock and a core component stock into; stock reservoirs (3A,3), a filter (6), a first distributing plate (7), a second distributing plate (9) on the back surface of which parallel, equally spaced and linear distributing grooves (10A,10) are engraved, and on the ventral surface of which pressure-controlling holes (11A,11) are bored, an eccentricity-controlling plate (14) on the back surface of which a plurality of grooves (15) for eccentricity are engraved and on the ventral surface of which introducing holes (16) are provided so that the center thereof is positioned eccentrically in the plane of the groove for eccentricity, a nozzle plate (17) with spinning holes (18) at a position where holes (11) are concentric with said introducing holes (16); The sheath component pressure-controlling holes (11A) are arranged so as to be positioned at the intersection of a square or rectangular lattice; and the core component pressure-controlling holes (11) are arranged so as to be positioned at the intersection of two diagonals of the quadrilateral formed by four adjacent sheath component pressure-controlling holes.</p> |
