A seamless webbing loop of a rock climbing quickdraw is disclosed in the disclosure, the webbing loop includes a winding yarn and a webbing. The winding yarn is an annular yarn formed by a single yarn that winds into circles or formed by a plurality of combined closed annular coils; the winding has an annular shape, and is provided with an opening on its radially inner face, where the opening is configured to receive the annular yarn, so that the annular yarn can be wrapped by the winding; and the quickdraw is sewn with a stitching thread. The annular yarn formed by winding overcomes the defect of the seam between the abutted ends of a webbing in the prior art, thus making the quickdraw more strong and safe. The disclosure has simple processes and is strong, safe and durable, and is seamless after the webbing loop is sewn. |
