Abstract: A loosening prevention lace which overcomes the problems where the lace is slackened or undone upon the lace being tied up through the eyelets for fastening the shoes, garment and as such and which brings unforeseen effect on design or appearance as well. The loosening prevention lace is provided by weaving one picot forming linear body or a plurality of picot forming linear bodies into a tubular woven fabric in a warp yarn direction thereof and protruding one picot forming linear body or a plurality of picot forming linear bodies from a surface of the tubular woven fabric with a certain interval over a longitudinal direction of the tubular fabric in a loop form.
