Segmented water-soluble yarn, hollow fabric formed by segmented water-soluble yarn and production method thereof

The invention discloses a segmented water-soluble yarn, a hollow fabric formed by the segmented water-soluble yarn and a production method thereof. The production method of the segmented water-solubleyarn comprises the following steps: carrying out a differential spinning frame process and a spooling process on first rough yarns and second rough yarns to obtain a segmented water-soluble yarn; preparing fibers of the first rough yarns, wherein the fibers of the first rough yarns at least comprise water-soluble fibers, the second rough yarns are rough yarns obtained by blending one or more second fibers, and the water-soluble fibers comprise water-soluble vinylon fibers. According to the water-soluble yarn in the segmented water-soluble yarn obtained by the method disclosed by the invention, the water-soluble yarn is attached to the surface of the yarn in a segmented manner, the whole yarn is segmented after water-soluble treatment in a later process, and the fabric can show different burnt-out and hollowed-out
