Abstract

This stuffed article ( 1 ) of the present invention is made of ticking ( 2 a, 2 b ) 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.

Claims (21)

1. A stuffed article, comprising:

a ticking filled with a stuffing,

wherein the stuffing comprises a long-fiber wad comprising an effect yarn and a core yarn air-entangled and integrated with each other, wherein the effect yarn is opened to form loop-like fibers;

a weight ratio of the effect yarn to the core yarn and the effect yarn together is 80 to 99% by weight(wt %), and

a plurality of strings of the long-fiber wad are arranged in parallel in at least one direction and sewn to the ticking such that the strings are integrated with the ticking.

2. The stuffed article according to claim 1 , wherein the long-fiber wad has a weight per unit length of 0.05 to 1.5 g/m.

3. The stuffed article according to claim 1 , wherein the effect yarn and the core yarn comprise at least one infusible fiber selected from the group consisting of a polyester fiber, a nylon fiber, and a polypropylene fiber.

4. The stuffed article according to claim 1 , wherein the stuffed article is at least one selected from the group consisting of a comforter/quilt, a blanket, a sleeping bag, a pillow, a cushion, a mat, a stuffed toy, a leg sheet, a jacket, pants, a vest, a coat, cold-protection clothing, and a neck-warmer.

5. The stuffed article according to claim 1 , wherein the long-fiber wad has a weight per unit length of 0.01 to 3 g/m.

6. The stuffed article according to claim 1 , wherein the effect yarn and the core yarn are not fused.

7. The stuffed article according to claim 1 , wherein a silicone-treatment agent is fixed by heat to the long-fiber wad.

8. The stuff article according to claim 7 , wherein an amount of silicone-treatment agent adhered is in a range of 0.1 to 10 wt % with respect to a total weight of the effect yarn and the core yarn in a dried state.

9. A method for manufacturing a stuffed article having a ticking filled with a stuffing, the method comprising:

twisting an effect yarn and a core yarn and opening loop-like fibers of the effect yarn so as to form a long-fiber wad, or subjecting an effect yarn and a core yarn to a combining-entangling treatment with an air-entanglement device and opening the effect yarn as required so as to form a long-fiber wad, wherein a weight ratio of the effect yarn to the core yarn and the effect yarn together is 80 to 99% by weight (wt %); and

arranging a plurality of strings of the long-fiber wad in parallel in at least one direction and sewing to the ticking to be integrated with the ticking.

10. The method for manufacturing a stuffed article according to claim 9 , wherein the long-fiber wad has a weight per unit length of 0.05 to 1.5 g/m.

11. The method for manufacturing a stuffed article according to claim 9 , wherein the effect yarn and the core yarn comprise at least one infusible fiber selected from the group consisting of a polyester fiber, a nylon fiber, and a polypropylene fiber.

12. The method for manufacturing a stuffed article according to claim 9 , wherein the stuffed article is at least one selected from the group consisting of a comforter/quilt, a blanket, a sleeping bag, a pillow, a cushion, a mat, a stuffed toy, a leg sheet, a jacket, pants, a vest, a coat, cold-protection clothing, and a neck-warmer.

13. The method for manufacturing the stuffed article according to claim 9 , wherein the effect yarn and the core yarn are not fused.

14. The method for manufacturing the stuffed article according to claim 9 , wherein a silicone-treatment agent is sprayed on the long-fiber wad and a thermal treatment is carried out.

15. The method for manufacturing the stuffed article according to claim 14 , wherein an amount of the sprayed silicone-treatment agent is in a range of 0.1 to 10 wt % with respect to a total weight of the effect yarn and the core yarn in a dried state.
