Example Embodiment

[0018] See Figure 1-3 , A spinneret provided by an embodiment of the present invention is fixed on the assembly body 10; the spinneret includes a plate body 3, a flow dividing device, a filtering device and a flow guide device.

[0019] The board body 3 is fixedly connected to the assembly body 10.

[0020] The shunting device is connected to the board 3.

[0021] The filtering device is arranged on the shunting device.

[0022] The guide device is arranged in the plate body 3 in a straight line.

[0023] Wherein, the melt enters the plate body 3 through the filter device, and then sequentially enters the guide device for spinning.

[0024] The structure of the shunt device is introduced in detail.

[0025] The flow dividing device includes: a flow dividing column 9.

[0026] The shunt column 9 is connected to the board 3. The upper end of the shunt column 9 is a spherical surface. The lower end of the shunt column 9 is in interference fit with the plate 3.

[0027] The structure of the...

Abstract

The invention discloses a spinneret, and belongs to the field of spinning technology. In the spinneret, a board body is fixedly connected with an assembly body, a shunting device is connected with the board body, a filtering device is arranged on the shunting device, and a linear guide device is disposed in the board body. By adopting the spinneret, fiber cooling intensity and fiber hygroscopic capacity under a function of side wind are uniform, the speed, the temperature and the humidity of the side wind in the same section are uniform, the filament number, the crystallinity and the orientation degree can be made uniform, the stretching performance of a fiber can be improved, and irregularity of fiber strength and elongation can be reduced.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinneret. Background technique [0002] In the production of chemical fiber spinning, the melt is sprayed out from the spinneret hole and enters the side blowing device for cooling. The spinneret in the prior art adopts the method of distributing holes on the entire spinneret surface such as concentric circles, rhombuses, and gypsophila. This way of distributing holes, the distance from different fibers on the same spinneret to the side blowing tuyere Inconsistency, this causes the cooling strength of each fiber and the moisture absorption of each fiber to be different by side air blowing. The cooling strength and moisture absorption of the fibers are large, and the cooling strength and moisture absorption of the fibers away from the side blowing are small, which will immediately affect the tensile properties of the nascent fibers, resulting in an increase in fiber strength ...
