Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of skin-core composite spinneret, which has the advantages of long service life and no eccentricity, and solves the problem of spinning with two or more polymers that are not mixed together. In the filament die, at the stage of fusion of two materials, due to the high temperature and the uncertainty of manual disassembly, the shape of the spinning die conduit is prone to change, such as eccentricity and deformation.

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1-2 , a new skin-core composite spinneret, comprising a spinneret main body 1, the outer surface of the spinneret main body 1 is provided with a placement connection groove, and the top of the spinneret main body 1 is provided with a hole extending to the inside of the spinneret main body 1. Connecting the through hole 5, the top of the spinneret main body 1 is provided with a spinneret conduit 3 passing through the spinneret main body 1, th...

Abstract

The invention relates to the technical field of spinnerets and discloses a novel leather core composite spinneret. The novel leather core composite spinneret comprises a spinneret body, a connecting hole extending to the inside of the spinneret body is formed in the top of the spinneret body, and spinneret guide tubes penetrating the spinneret body are arranged in the top of the spinneret body. The novel leather core composite spinneret has the advantages that by setting up four multilateral stabilizing grooves evenly in the inner wall of the spinneret guide tubes, the shape of the spinneret guide tubes is changed so that the leather-core separation is clear, no eccentricity is caused, the service life of the spinneret is long, and the utilization rate of the equipment can be effectively improved; meanwhile, the production efficiency of products is improved, the strength and toughness of the equipment are effectively improved and the shape change of the spinneret guide tubes, such as eccentricity and modification, due to the uncertainty of high temperature and manual disassembly is effectively avoided by changing the spinneret guide tubes from cylindrical to irregular.

Description

technical field [0001] The invention relates to the technical field of spinnerets, in particular to a novel skin-core composite spinneret. Background technique [0002] In recent years, polyester fiber has made up for the shortage of natural fiber production and has developed rapidly. While polyester fiber is rapidly expanding and developing, conventional polyester fiber is far behind in terms of comfort, diversity, functionality and bionicity. It cannot meet the growing needs of the people, so various differentiated and functional polyester fibers are applied. [0003] In the composite spinning die of two or more immiscible polymers, at the stage of fusion of the two materials, the shape of the spinning die conduit is prone to change due to high temperature and uncertainty of manual disassembly, such as Eccentricity and deformation have brought a lot of inconvenience to users and reduced production efficiency. Therefore, a new skin-core composite spinneret is proposed to s...
