Abstract

The invention discloses an embedded-needle spinneret for hollow fiber spinning, which comprises a top plate; two spinning-liquid feed pipes vertically pass through the top plate, and an embedded-needle expansion link vertically passes through the central position of the top plate; a needle plate is close to a base plate of the spinneret, and the embedded-needle expansion link is connected with the two ends of the needle plate by two connecting rods; and the base plate is provided with a plurality of embedded needles and a plurality of spinning holes, and each embedded needle passes through a corresponding spinning hole. The embedded-needle spinneret has the advantages of simple structure, stable hole form, and wide application range.

Description

technical field [0001] The invention relates to an embedded needle spinneret for hollow fiber spinning. Background technique [0002] At present, in dry spinning, hollow fibers are obtained by physical and chemical methods, but in wet spinning, it is difficult to obtain hollow fibers. Some hollow fibers obtained by chemical methods are very unstable in shape and cannot be achieved. Production requirements. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide an embedded needle spinneret for hollow fiber spinning with simple structure, stable hole shape and wide application range. [0004] The object of the present invention is achieved through the following technical solutions: a needle-inlay spinneret for hollow fiber spinning, comprising a top plate of the spinneret, and two spinning liquids are vertically penetrated in the top plate of the spinneret In the input pipe, the center of the top plate is v...
