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.
Claims18
A shoe lace for threading through eyelets of a shoe and tying with a bow-knot to secure the shoe comprising a plurality of strands of at least one standard yarn having a substantially non-varying cross section along its length and at least one special yarn having enlarged regions resulting in a cross section variable along its length, said standard yarn and said special yarn being interlaced whereby the enlarged regions form protuberances distributed over an outer surface of the lace for resisting untying of a bow-knot made with the lace and slippage of the lace through the eyelets.
