ABSTRACT:
A slip resistant shoe lace is produced by weaving or braiding a plurality of standard yarns with special yarns. The special yarns have a special effect in the form of slubs or eccentricities at regular intervals or throughout the length of the yarn and when woven or braided along with the standard yarns produce protuberances along the length of the shoe lace for resisting untying of the lace.
