Embodiment 1

[0035] The embodiment of the present application discloses a polyester fiber.

[0036] refer to figure 1 , the polyester fiber includes a fiber body 1, and the cross section of the fiber body 1 is arranged in a rectangular shape. The fiber body 1 is integrally formed with a fiber convex strip 2 parallel thereto, and the length of the fiber convex strip 2 is equal to that of the fiber body 1 .

[0037] refer to figure 1 One fiber protruding strip 2 is respectively provided on opposite sides of the fiber body 1 , and the fiber protruding strip 2 is located at the midpoint of the cross-section fiber body 1 in the length direction.

[0038] refer to figure 1 , the fiber convex strip 2 formed integrally outside the fiber body 1 enhances the structural strength of the fiber body 1 appearance, thereby improving the rigidity of the fiber body 1, thereby making the fiber body 1 less prone to bending deformation and having better looseness.

Embodiment 2

[0042] The embodiment of the application also discloses a spinneret used for polyester fiber production, refer to figure 2 , a spinneret used for polyester fiber production, including a main board 3, the main board 3 is provided with extrusion holes that run through the main board 3, and the extrusion holes are provided with six circles along the direction away from the axis of the main board 3. The extrusion holes are arranged in a circular array around the axis of the main board 3 .

[0043] refer to image 3 , the extrusion hole includes a feed hole 31, a transition hole 32 and a forming hole, the transition hole 32 is located between the feed hole 31 and the forming hole, and the inner diameter of the transition hole 32 gradually becomes smaller along the direction from the feeding hole 31 to the forming hole .

[0044] The transition hole 32 is provided, on the one hand, when the polyester material is squeezed into the forming hole from the transition hole 32, the poly...

Abstract

The invention relates to a polyester fiber. The polyester fiber comprises a fiber body with a rectangular section, and fiber raised lines parallel to the fiber body are integrally formed outside the fiber body. The polyester fiber has the advantage that the fluffy performance of the polyester fibers is improved.

Description

technical field [0001] The invention relates to the field of fiber manufacturing, in particular to a polyester fiber and a spinneret used for its production. Background technique [0002] Polyester fiber is currently the most widely used synthetic fiber in the apparel industry, and is favored by users because of its excellent physical and chemical properties. With the improvement of people's living standards, higher requirements have been put forward for the comfort of clothing. [0003] At present, the cross-section of the fiber filament made of polyester fiber is generally rectangular, so when the fiber filament is subjected to a force, the fiber filament is relatively prone to bending deformation. When people wear clothing made of fiber filaments, the clothing is squeezed by the human body and the fiber filaments are compressed, resulting in poor air permeability of the clothing. Contents of the invention [0004] In order to improve the problem of poor bulkiness of p...
