Title:
静電紡糸用スピナレット
Document Type and Number:
Japanese Patent JP6881651
Kind Code:
B2
Abstract:
To provide a spinneret for electrostatic spinning, enabling stabilization of continuous spinning of low-viscosity raw material fluid and suitable for electrostatic spinning of wide-viscosity raw material fluids.SOLUTION: The spinneret 1 for electrostatic spinning is constituted of a structure of an electro-conductive metal material, wherein the structure is assembled with a longitudinal X, a short axial direction Z, and a thickness direction Y, an inflow port for a raw material fluid for spinning is assembled on one side 22 of the structure, a plurality of projections 5 are formed along the longitudinal direction on the other one side 21, each of a plurality of projections extends so as to protrude from the structure, the projection has a discharge hole 4 for discharging a raw material fluid to its apex 2, and a pitch P of the discharge hole exceeds 1 mm.SELECTED DRAWING: Figure 1
