Abstract

Abstract A spinneret assembly for conjugate spinning includes (1) a spinneret plate provided with a number of spinning holes and (2) a distribution plate superposed closely upon the upper face of the spinneret plate onto which two kinds of spinning liquids are to be fed, and the distribution plate is arranged in such a manner that, of separate spinning liquid paths for the two kinds of spinning liquid comprising a number of separate and parallel inlet grooves for receiving individually and alternately the two kinds of spinning liquids fed from above and guide paths for guiding individually the two kinds of spinning liquids fed out of the inlet grooves onto upper openings of the spinning holes in the spinneret plate, it is provided with at least said guide paths, a part or whole of each of which forms a pressure-adjusting means. Liquid storing chambers are provided on the lower face of the distribution plate at positions corresponding to the spinning holes. Each of the liquid storing chambers is recessed at the upper portion, and has at least one diameter longer than the diameter of the upper openings of the corresponding spinning hole, and is provided with two guide paths for guiding the two kinds of spinning liquid fed individually out of the adjacent two inlet grooves to both ends of the longer diameter of each of the liquid storing chambers. A part of whole of each of the guide paths extending to both ends of each of the liquid storing chambers forms pressure-adjusting means or holes having a cross-sectional area smaller than the cross-sectional area of each of the liquid storing chambers perpendicular to the longer diameter.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 279 words
A spinneret assembly for conjugate spinning, including (1) a spinneret plate provided with a number of spinning holes and (2) a distribution plate superposed closely upon the upper face of said spinneret plate onto which two kinds of spinning liquids are to be fed, and arranged in such a manner that, of separate spinning liquid paths for said two kinds of spinning liquid comprising a number of separate and parallel inlet grooves for receiving individually and alternately said two kinds of spinning liquid fed from above and guide paths for guiding individually said two kinds of spinning liquids fed out of said inlet grooves onto upper openings of said spinning holes in said spinneret plate, it is provided with at least said guide paths, a part or whole of each of which forms a pressure-adjusting means, wherein: liquid storing chambers are provided on the lower face of said distribution plate at positions corresponding to said spinning holes, each of said liquid storing chambers being recessed at the upper portion and having at least one diameter longer than the diameter of the upper openings of the corresponding spinning hole, each of said liquid storing chambers being provided with two guide paths for guiding said two kinds of spinning liquids fed individually out of the adjacent two inlet grooves to both ends of said longer diameter of each of said liquid storing chambers, and a part or whole of each of said guide paths extending to both ends of each of said liquid storing chambers forming pressure-adjusting means or holes having a cross-sectional area smaller than the cross-sectional area of each of said liquid storing chambers perpendicular to said longer diameter.
Claim 2
Dependent Claim 279 words
A spinneret assembly for conjugate spinning, including (1) a spinneret plate provided with a number of spinning holes and (2) a distribution plate superposed closely upon the upper face of said spinneret plate onto which two kinds of spinning liquids are to be fed, and arranged in such a manner that, of separate spinning liquid paths for said two kinds of spinning liquid comprising a number of separate and parallel inlet grooves for receiving individually and alternately said two kinds of spinning liquid fed from above and guide paths for guiding individually said two kinds of spinning liquids fed out of said inlet grooves onto upper openings of said spinning holes in said spinneret plate, it is provided with at least said guide paths, a part or whole of each of which forms a pressure-adjusting means, wherein: liquid storing chambers are provided on the lower face of said distribution plate at positions corresponding to said spinning holes, each of said liquid storing chambers being recessed at the upper portion and having at least one diameter longer than the diameter of the upper openings of the corresponding spinning hole, each of said liquid storing chambers being provided with two guide paths for guiding said two kinds of spinning liquids fed individually out of the adjacent two inlet grooves to both ends of said longer diameter of each of said liquid storing chambers, and a part or whole of each of said guide paths extending to both ends of each of said liquid storing chambers forming pressure-adjusting means or holes having a cross-sectional area smaller than the cross-sectional area of each of said liquid storing chambers perpendicular to said longer diameter.
Claim 3
Dependent Claim 75 words
A spinneret assembly as recited in Claim 1, wherein a portion of each of said guide path extending from its inlet open in each of said inlet grooves to both ends of said longer diameter of each of said liquid storing chambers comprises a common, larger-diameter guide path section on the side of each inlet groove and branched path sections extending from the lower end thereof to the adjacent left and right liquid storing chambers.
