[0002] There is a prior Chinese utility model patent with the patent number CN201520026083.1 and the name of "An anti-perspective profiled fiber", which discloses an anti-perspective profiled fiber. The cross-sectional structure of the single filament of the anti-perspective profiled fiber includes an outer layer and an inner core. There is a hollow structure between the outer layer and the inner core. The outer layer and the inner core are connected by a plurality of filaments. The filaments divide the space between the outer layer and the inner core into several ventricular chambers. The prepared fiber can effectively reduce the transmittance of visible light, thereby improving the perspective performance. In addition, due to its hollow structure, it has a relatively high shrinkage. However, there is still room for improvement in the elasticity, water absorption, and antibacterial property of this profiled fiber. Therefore, the structure of this profiled fiber needs to be further improved. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a polyester cotton-like fiber with good elasticity and water absorption in view of the above-mentioned prior art situation.

The inner core is placed in the inner cavity of the outer layer. The outer layer and the inner core are connected by a plurality of filaments. The filaments divide the space between the outer layer and the inner core into several ventricular chambers. The characteristics are that: the outer layer is oval, the inner core is located at the center of the oval, and there are gaps penetrating through the outer layer and the filaments on the outer layer.

[0005] As an improvement, the gap preferably penetrates through the inner core.

[0006] As a further improvement, the width of the gap is preferably 0.3 - 0.5 times the thickness of the filament.

[0007] As a further improvement, there are preferably four filaments, and the four filaments are distributed in a cross shape.

[0008] As a further improvement, auxiliary filaments are preferably arranged between the outer layer and the inner core. The auxiliary filaments divide the corresponding ventricular chamber into a large chamber cavity and a small chamber cavity 13 with different sizes.

[0009] As a further improvement, the auxiliary filaments are preferably arc-shaped, and the root of the auxiliary filaments is integrally connected with the filaments.

[0010] As a further improvement, the small chamber cavity is preferably connected to the outside of the outer layer, and an antibacterial body is filled in the small chamber cavity. The antibacterial body is flush with or protrudes from the outer surface of the outer layer.

[0011] As an improvement, the thicknesses of the outer layer, the inner core, the filaments, and the auxiliary filaments can preferably be the same.

[0012] As an improvement, the inner core can preferably be circular.

[0013] As a further improvement, the diameter of the inner core can preferably be less than 0.25 of the narrow diameter of the outer layer.

[0014] Compared with the prior art, the advantages of the present utility model are as follows: The outer layer adopts an elliptical structure, and there can be a larger cavity in the direction of the wide diameter of the ellipse, thereby increasing the elasticity of the fiber. Since the cavity is filled with air, the light transmittance is reduced, giving the fiber a good anti-perspective effect; There are notches penetrating through the outer layer and the filaments, and the notches can communicate with the inner core. The notches can serve as gaps for accommodating liquid, increasing the water absorption of the fiber; An antibacterial body can be embedded in the small chamber cavity, thereby increasing the antibacterial effect of the fiber.
