[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments.

[0017] Elastic polyester yarn, such as Figure 1 As shown, it includes a main body 1, a plurality of cavities 11 are opened in the main body 1, and a pair of symmetrically arranged support bars 14 are provided in the cavities 11. A guide portion 12 is formed on the surface of the main body 1 for guiding the main body 1 to elastically curl into the plurality of cavities 11 when under pressure. When the cavity 11 is deformed due to the curling of the main body 1, the support bar 14 elastically abuts the inner wall of the cavity 11. In this specific embodiment, the main body 1 is made of polyester material by spinning.

[0018] Beneficial effect: When the polyester yarn is under pressure, it can elastically curl into several cavities 11 due to the cavity 11 structure, and use the elastic deformation of the material to form a better elastic effect. At the same time, the setting of the support strip 14 also improves the rebound effect of the cavity 11 when it is under pressure, so that the elastic recovery effect of the polyester yarn is better.

[0019] like Figure 1As shown, specifically, the guide portion 12 includes a concave portion distributed on one side of the main body 1 and a convex portion on the other side of the main body 1. The diameter of the concave portion is equal to the diameter of the convex portion and is larger than the outer diameter of the main body 1. The cross-section of each pair of support bars 14 is a C-shaped structure with openings facing opposite directions. The cavity 11 is surrounded by the support bars 14 on the side away from the support bars 14 to form a clearance area 111.

[0020] like Figure 1 As shown, in order to further improve the effect of the main body 1 being able to bend and deform into several cavities 11 when several cavities 11 are divided, the middle positions of adjacent cavities 11 are separated by a separator 13 integrally formed with the main body 1, and the projection of the separator 13 toward the concave portion is located in the middle position of the concave portion. In order to make the bending deformation of the main body 1 more subjectively guided, several fastening yarns 2 are wrapped around the surface of the main body 1, and the fastening yarns 2 tighten the main body 1 by winding.
