Abstract

A shoelace is provided, including: a core material and a cover layer. The core material defines an axial direction, and the cover layer is sleeved on the core material. The cover layer covers 30% to 90% of an area of an outer peripheral surface of the core material. Therefore, the shoelace has a concave-convex outer surface and is not easy to loosen when tied, and provides good structural strength and appearance.

Claims (9)

1. A shoelace, including:

a core material, defining an axial direction; and

a cover layer, sleeved on the core material, the cover layer covering 30% to 90% of an area of an outer peripheral surface of the core material;

wherein the cover layer includes a plurality of strands which are knitted with one another and forms a plurality of loops sleeved with one another.

2. The shoelace of claim 1 , wherein the plurality of loops partially form a plurality of rib portions and a plurality of connecting portions, the plurality of rib portions extend in the axial direction and spacingly arranged around the core material, each of the plurality of connecting portions is connected between adjacent two of the plurality of rib portions, and each of the plurality of connecting portions includes a plurality of linear segments extending in different directions.

3. The shoelace of claim 1 , wherein the cover layer includes at least one first section and at least one second section connected with one another, and the at least one first section and the at least one second section are knitted differently.

4. The shoelace of claim 1 , wherein the cover layer includes at least one first section and at least one second section connected with one another, and each said first section has a first diametrical dimension, and each said second section has a second diametrical dimension larger than one said first diametrical dimension.

5. The shoelace of claim 1 , wherein the cover layer includes at least one first section and at least one second section connected with one another, and each said first section includes a plurality of first meshes, each said second section includes a plurality of second meshes larger than the plurality of first meshes, and diametrical dimensions of the plurality of second meshes adjacent to one said first section are smaller than diametrical dimensions of the plurality of second meshes remote from the said first section.

6. The shoelace of claim 5 , wherein a diametrical dimension of each of the plurality of second meshes is larger than or equal to ½ of a diameter of the core material.
