Shoelace

1. A shoelace, including:

a core material, defining an axial direction; and

a woven layer, sleeved on the core material, including a plurality of strands, a plurality of ridge portions and a plurality of connecting portions, the plurality of ridge portions and the plurality of connecting portions being woven by the plurality of strands and arranged alternatively in a circumferential direction of the core material;

wherein each of the plurality of strands extends meanderingly along the axial direction and includes a plurality of first loops and a plurality of second loops which are arranged alternatively, and every adjacent one of the plurality of first loops and one of the plurality of second loops have a connecting segment connected therebetween;

wherein in the axial direction, extending directions of every adjacent two of said connecting segments are non-parallel;

wherein in the axial direction, every adjacent two of said connecting segments and one of the plurality of ridge portions define a mesh with a roughly triangular shape therebetween, and the core material is exposed outwardly from said meshes.

2. The shoelace of claim 1 , wherein the plurality of first loops of one of the plurality of strands are sleeved with the plurality of second loops of another one of the plurality of strands to form one of the plurality of ridge portions.

3. The shoelace of claim 1 , wherein a number of the plurality of strands is equal to a number of the plurality of ridge portions.

4. The shoelace of claim 1 , wherein a stretch ratio of each of the plurality of strands is smaller than a stretch ratio of the core material.

5. The shoelace of claim 1 , wherein as viewed in the axial direction, each of the plurality of connecting portions at least partially extends along an imaginary plane parallel to the axial direction, and said imaginary planes define a polygon outline therebetween.

6. The shoelace of claim 1 , wherein the plurality of ridge portions are equiangularly arranged around the core material.

7. The shoelace of claim 1 , wherein the plurality of first loops of one of the plurality of strands are sleeved with the plurality of second loops of another one of the plurality of strands to form one of the plurality of ridge portions; said connecting segments of one of the plurality of strands define one of the plurality of connecting portions; each of the plurality of first loops extends in a first direction, each of the plurality of second loops extends in a second direction, and the first direction and the second direction are non-parallel to each other and non-parallel to an extending direction of one of said connecting segments; a number of the plurality of strands is equal to a number of the plurality of ridge portions; as viewed in the axial direction, each of the plurality of connecting portions at least partially extends along an imaginary plane parallel to the axial direction, and said imaginary planes define a polygon outline therebetween; the polygon outline is triangular or rectangular; a stretch ratio of each of the plurality of strands is smaller than a stretch ratio of the core material; a wire diameter of each of the plurality of strands is smaller than a wire diameter of the core material; each of the plurality of ridge portions radially protrudes beyond each of the plurality of connecting portions; and at least a portion of the woven layer is stretchable and slidable relative to the core material in the axial direction.
