Slip-resistent shoelace

Abstract

A slip-resistant shoelace of the present invention includes a body having an external tube. The external tube is manufactured by weaving. Each of Pluralities of sections of a cavity of the external tube is filled with a center core respectively. The center cores are arranged at intervals to be discontinuous. Thus, sections having the center core are solid, and sections without the center core are hollow. The hollow sections can be used to be disposed in a shoelace hole stably or to be tied and knotted tightly. Thereby, the slip-resistant shoelace of the present invention can prevent the knot from slipping.

What is claimed is: 
     
         1 . A slip-resistant shoelace, including a body, the body including an external tube which is formed by weaving, a center core being filled in a section of a cavity of the external tube, the section of the body having the center core being solid, a section of the body without the center core being hollow, the hollow section of the body is able to be disposed in a shoelace hole stably and to be tied and knotted tightly. 
     
     
         2 . The slip-resistant shoelace of  claim 1 , wherein the body has a plurality of center core, the center cores are arranged in the cavity of the external tube at intervals. 
     
     
         3 . The slip-resistant shoelace of  claim 1 , wherein the center core and the external tube are manufactured by weaving respectively, the center core is installed into the cavity of the external tube simultaneously when the external tube is being manufactured by weaving. 
     
     
         4 . The slip-resistant shoelace of  claim 1 , wherein the external tube has a constant outer diameter. 
     
     
         5 . The slip-resistant shoelace of  claim 1 , wherein the center core is positioned but not fixed by the external tube, the center core is able to be separated from the external tube.
