(27) Preferably, the Warp A, B, C, D are a group, each warp yarn is independently controlled to move upward and downward, three of Warp A, B, C, D are required to move in the opposite direction of the other one, thereby forming the upper and lower layers. A group of four warp yarns in each fore-and-back trip have only one warp yarn interweaving and locking with the weft 1 yarn, thereby forming lock sites (see FIG. 1), and the lock sites of respectively four successive fore-and-back trips locate on different warp yarns, each lock site is not at the same position, thereby forming misaligned pair lock of the upper and lower layers.

A single side edge of the braid may include five, six, seven or more warp yarns, which may arbitrarily select the starting point to form a four-lateral-four-longitudinal structure, and the structure is required to conform to a three-sinking-one-floating or three-floating-one-sinking form.

(29) In the above-described tissue forms, the lock sites of the structure of two side edges of the braid are shown in FIG. 1, herein the solid points are sinking lock sites and the dotted line points are the floating lock sites. By the above-described tissue forms, the structure of two side edges of the braid enables the sinking and floating of the upper and lower layers misalign properly, forming misaligned positions of warp yarns so as to make the weft 1 yarn weave pair locks.

(30) The above-described pair locks weaved by the weft 1 yarn are able to utilize the tightness of the back trip of the weft to reduce the exposure of the weft at the overlock, thereby forming elastic band with shaggy, fluffy and soft round corners at the left and right sides that are symmetrical and have no difference in shape. Thus, the structures of the left and right edges of the braid form shaggy, fluffy and soft round corners, so as to not scratch when contacting with the skins, and wear more comfortably. FIG. 10 is a view of the braid in the present application.
