Abstract

The invention relates to a multiple-hollow-fiber spinneret plate which comprises a circular spinneret plate body. The spinneret plate body is provided with a plurality of spinneret holes. The multiple-hollow-fiber spinneret plate is characterized in that a micro pore of each spinneret hole is formed by splicing two layers of coaxial ring holes, the section shape of each first layer ring hole comprises fourteen C-shaped gaps, the C-shaped gaps are distributed in the same direction in a circular ring shape, and the section shape of each second layer ring hole is formed by reversely connecting two semi-circular gaps in a crossed mode. According to the multiple-hollow-fiber spinneret plate, a hollow fiber with 19 holes can be produced, the hollowness degree is good, and performance is excellent.

Description

technical field [0001] The invention relates to a spinning accessory, in particular to a multi-hollow fiber spinneret. Background technique [0002] Hollow fibers have the characteristics of high bulkiness, good elasticity, strong warmth retention, soft and smooth feel, good resilience, and good coverage, and are widely used. The following methods are generally used for spinning hollow fibers: (1) foaming agent method, (2) positioning blowing method, (3) reprocessing method, (4) inserting column nozzle, (5) inserting tube nozzle, (6) Shaped spinneret method. The necessary condition for the production of hollow fibers by the special-shaped spinneret method is to design and process the spinneret, because the polymer melt ejected from the spinneret hole and the formed fiber after cooling not only require one or several continuous different The discontinuous hollow cavity also requires the fiber to have a cross-section with a non-circular profile. [0003] At present,...
