  • Patent number: 9670054
    Abstract: This stuffed article (1) of the present invention is made of ticking (2a, 2b) filled with a stuffing. The stuffing is a long-fiber wad (8) formed by integrating an effect yarn with a core yarn. The effect yarn is opened to form loop-like fibers. A plurality of strings of the long-fiber wad (8) are arranged in parallel in at least one direction, and sewn to the ticking so as to be integrated with the ticking. The long-fiber wad in the stuffed article is fixed to the ticking, and the effect yarn is integrated with the core yarn. Therefore, the present invention can provide a stuffed article where the displacement of the long-fiber wad is limited even after repeated washing, the wad is less concentrated, and the bulkiness is high.
