Abstract: A light-emitting warning rope is provided with one end connected to a tent and other end connected to an anchoring point. The light-emitting warning rope is disposed between the anchoring point and the tent to provide a tension to set the tent upright. The rope comprises a light-emitting core and a structural rope. The structural rope comprises a plurality of bearing yarns which is knitted into a strip body with the light-emitting core as an axis, and the strip body knitted by each bearing yarn is knitted in a mesh shape on the radial side and has a plurality of gaps through which light from the light-emitting core is transmitted. In any segment of the rope, the light-emitting core has a stretching length less than that of each bearing yarn, so that the axial tension acts substantially on the bearing yarns when the rope suffers an axial tension.
