Abstract

A woven fabric having a high shrinkage yarn that has a predetermined shrinkage ratio and a low shrinkage yarn that has a relatively lower shrinkage ratio than the high shrinkage yarn, includes an inductive portion that is formed by the high shrinkage yarn, and allows displacement in a planar direction. At least a portion of the low shrinkage yarn is engaged with the inductive portion and bent in the planar direction.

Claims

1. A woven fabric having a high shrinkage yarn that has a predetermined shrinkage ratio and a low shrinkage yarn that has a relatively lower shrinkage ratio than the high shrinkage yarn, comprising:

an inductive portion that is formed by the high shrinkage yarn, and allows displacement in a planar direction,

wherein at least a portion of the low shrinkage yarn is engaged with the inductive portion and bent in the planar direction.

2. The woven fabric according to claim 1, wherein the inductive portion includes a first inductive portion that allows displacement in a predetermined direction of the planar direction, and a second inductive portion that allows displacement in a direction opposite the predetermined direction of the planar direction, the first inductive portion being formed alternately with the second inductive portion;

and the at least a portion of the low shrinkage yarn is engaged with the inductive portion and bent alternately in the predetermined direction and in the direction opposite the predetermined direction of the planar direction.

3. The woven fabric according to claim 2, further comprising a restraining portion that is formed by the high shrinkage yarn between the first inductive portion and the second inductive portion, and with which the low shrinkage yarn engages, and in which a range over which the displacement of the low shrinkage yarn is allowed is smaller than that of the inductive portion.

4. The woven fabric according to claim 2, wherein the inductive portion is a location where a yarn skipping amount of the high shrinking yarn that straddles yarn orthogonal to the high shrinkage yarn is larger than at another location.

5. The woven fabric according to claim 4, wherein a yarn skipping amount in the predetermined direction from a position where the low shrinkage yarn is engaged at the first inductive portion is greater than a yarn skipping amount in the direction opposite the predetermined direction from the position where the low shrinkage yarn is engaged at the first inductive portion;

and a yarn skipping amount in the direction opposite the predetermined direction from the position where the low shrinkage yarn is engaged at the second inductive portion is greater than a yarn skipping amount in the predetermined direction from the position where the low shrinkage yarn is engaged at the second inductive portion.

6. The woven fabric according to claim 1, wherein the inductive portion includes a first inductive portion that allows displacement in a predetermined direction of the planar direction, and second inductive portions that allow displacement in a direction opposite the predetermined direction of the planar direction, the first inductive portion being formed alternately with the second inductive portions;

and the at least a portion of the low shrinkage yarn is engaged with the inductive portion and bent alternately in the predetermined direction and in the direction opposite the predetermined direction of the planar direction.

7. The woven fabric according to claim 6, further comprising a restraining portion that is formed by the high shrinkage yarn between the first inductive portion and the second inductive portions, and with which the low shrinkage yarn engages, and in which a range over which the displacement of the low shrinkage yarn is allowed is smaller than that of the inductive portion.

8. The woven fabric according to claim 1, wherein the inductive portion includes first inductive portions that allow displacement in a predetermined direction of the planar direction, and a second inductive portion that allows displacement in a direction opposite the predetermined direction of the planar direction, the first inductive portions being formed alternately with the second inductive portion;

and the at least a portion of the low shrinkage yarn is engaged with the inductive portion and bent alternately in the predetermined direction and in the direction opposite the predetermined direction of the planar direction.

9. The woven fabric according to claim 8, further comprising a restraining portion that is formed by the high shrinkage yarn between the first inductive portions and the second inductive portion, and with which the low shrinkage yarn engages, and in which a range over which the displacement of the low shrinkage yarn is allowed is smaller than that of the inductive portion.

10. The woven fabric according to claim 1, wherein the inductive portion includes first inductive portions that allow displacement in a predetermined direction of the planar direction, and second inductive portions that allow displacement in a direction opposite the predetermined direction of the planar direction, the first inductive portions being formed alternately with the second inductive portions;

and the at least a portion of the low shrinkage yarn is engaged with the inductive portion and bent alternately in the predetermined direction and in the direction opposite the predetermined direction of the planar direction.

11. The woven fabric according to claim 10, further comprising a restraining portion that is formed by the high shrinkage yarn between the first inductive portions and the second inductive portions, and with which the low shrinkage yarn engages, and in which a range over which the displacement of the low shrinkage yarn is allowed is smaller than that of the inductive portion.

12. A double or multiple woven fabric comprising the woven fabric according to claim 1, wherein the low shrinkage yarn forms a portion of a layer on one side in a thickness direction.
