Detailed Description

The present utility model will be described in detail below with reference to the accompanying drawings and examples.

1-2, comprises a yarn core 1, a plurality of convex strips 2 are arranged on the yarn core 1, the convex strips 2 are arranged to extend the outer side of the yarn core 1 and form buffer support for the yarn core 1, an outer winding layer 3 is wound on the yarn core 1, the outer winding layer 3 is abutted against the convex strips 2, the winding of the outer winding layer 3 on the convex strips 2 enlarges the contact area between the polyester yarn and an external object, when the object is contacted with the polyester yarn, the polyester yarn is enabled to have compressible elasticity integrally by the convex strips 2, a first cavity 4 is formed between two adjacent convex strips 2, the first cavity 4 is formed by surrounding the two adjacent convex strips 2, the yarn core 1 and the outer winding layer 3, the polyester yarn is enabled to form recoverable elasticity through extrusion of the convex strips 2 in the extrusion process of the polyester yarn, when the extrusion force disappears, the polyester yarn is restored to the original state through the restoration of the shape of the convex strip 2, a plurality of first extension strips 5 and second extension strips 6 are arranged on the convex strip 2, part of the first extension strips 5 and the second extension strips 6 can form the support for the outer wrapping layer 3, part of the first extension strips 5 are arranged in the area of the first cavity 4, under the condition that the convex strip 2 is deformed, the support of the first extension strips 5 and the second extension strips 6 can avoid the excessive deformation of the convex strip 2 caused by the external pressure, the second extension strips 6 are in the bent shape and extend into the area of the first cavity 4, the bent end of the second extension strips 6 extend into the first cavity 4 and form the filling, so that under the condition that the polyester yarn is deformed when being extruded, the part of stretching into the first cavity 4 by the second extension strip 6 is abutted, the conditions of breakage and the like which are easy to occur when the convex strip 2 is extruded to the side are reduced, the service life of polyester yarns is prolonged, one end of the convex strip 2 is arranged on the yarn core 1, the other end of the convex strip 2 is far away from the yarn core 1, a plurality of first extension strips 5 are arranged at the middle section of the convex strip 2 and one end far away from the yarn core 1, the first extension strips 5 arranged at the middle section of the convex strip 2 can form abutted connection with the yarn core 1 when the convex strip 2 is deformed, the supporting effect on the convex strip 2 is formed, the supporting effect of the polyester yarns on the pressure is enhanced, and when the convex strip 2 is deformed, the supporting effect of the convex strip 2 and the first extension strips 5 on the pressure is simultaneously achieved.
