Abstract: A seamless elastic strap with forked structures and a manufacturing method thereof are provided, the elastic strap includes an upper layer fabric strap formed by interweaving an upper layer warp, an upper layer wrapped warp, and an upper layer weft and a lower layer fabric strap formed by interweaving a lower layer warp, a lower layer wrapped warp, and a lower layer weft. By changing the interweaving position of the upper and lower wrapped warps with the upper and lower wefts, a structure consisting of several forking parts and merging parts arranged at intervals on one elastic strap is achieved. It uses the staggered hot-cutting method to make the ends of both ends of the upper and lower fabric straps misaligned. It uses the ultrasonic welding method to form a loop fabric strap. It has the advantage of using adhesive pressing or ultrasonic welding to make seamless marks.
