Shoelaces for preventing natural loosening are provided to prevent the change of an original form and the color by impregnating or coating the woven strings with coating solution. The shoelaces for preventing natural loosening are produced by coating the completely finished shoelaces by entirely or partially soaking the shoelaces in the rubber latex, synthetic resin water soluble emulsion except silicone, synthetic resin copolymer emulsion, liquid synthetic resin, rubber, synthetic resin, and rubber solution melted in a solvent, or applying the solution on the shoelaces. And then, the coated shoelaces are dehydrated in a centrifugal separator and dried at the normal temperature or 130°C. Especially, the entire or a portion of the shoelaces is impregnated with one liquid material selected from liquid rubber, polyurethane solution, and polybutene solution.
