Definitions
- the invention relates to a woven fabric having a high shrinkage yarn that has a relatively high shrinkage ratio and a low shrinkage yarn that has a relatively low shrinkage ratio.
- JP 2010-261116 A A woven fabric having an insulating fiber (high shrinkage yarn) and conductive wire (low shrinkage yarn), as described in Japanese Patent Application Publication No. 2010-261116 (JP 2010-261116 A) below is known.
- JP 2010-261116 A describes a woven fabric having a structure in which a shrinking portion is provided at a predetermined location formed by an insulating fiber. This shrinking portion tends to shrink more at the predetermined location than at other locations. Also, the conductive wire bends in a planar direction when the shrinking portion shrinks.
- JP 2010-261116 A must have the shrinking portion that shrinks relatively easily, the aesthetics may be diminished due to the fact that this shrinkage portion shrinks more than the other portions.
- the invention thus provides a woven fabric in which disconnection of a low shrinkage yarn is inhibited without diminishing the aesthetics.
- a first aspect of the invention relates to 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.
- An inductive portion that allows displacement in a planar direction is formed by the high shrinkage yarn.
- At least a portion of the low shrinkage yarn is engaged with the inductive portion and bent in the planar direction.
- the inductive portion that is formed by the high shrinkage yarn and allows displacement in the planar direction causes the low shrinkage yarn to be induced in a predetermined direction of the planar direction and bend in that direction.
- disconnection of the low shrinkage yarn is able to be inhibited.
- the structure is not one that greatly shrinks the high shrinkage yarn locally as the related art does, so the aesthetics of the woven fabric will not be diminished.
- the inductive portion may include 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 may be engaged with the inductive portion and bent alternately in the predetermined direction and in the direction opposite the predetermined direction of the planar direction.
- the low shrinkage yarn bends alternately like a way by forming the first and second inductive portions alternately so as to allow displacement in the predetermined direction and the direction opposite the predetermined direction. That is, the structure is one in which the portions that are bent in the length direction of the low shrinkage yarn are formed substantially evenly, so the load bearing capacity and the like of the low shrinkage yarn is improved.
- the woven fabric having the structure described above may also include a restraining portion that is formed by the high shrinkage yarn between at least some of 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.
- the low shrinkage yarn is able to be inhibited from deviating from its position and the like by the restraining portion. Also, when the high shrinkage yarn shrinks, a predetermined portion of the low shrinkage yarn is held by the restraining portion, and portions of the low shrinkage yarn that are on both sides of this predetermined portion are induced by the inductive portion and bend in the planar direction.
- the portions on both sides of this portion are induced in the planar direction, so the effect of inhibiting the low shrinkage yarn from protruding in a direction that intersects the plane is further improved.
- a second aspect of the invention relates to a double or multiple woven fabric that includes the woven fabric described above, in which the low shrinkage yarn forms a portion of a layer on one side in a thickness direction.
- the structure is one in which the low shrinkage yarn is arranged on a layer on a back surface side of a double or multiple woven fabric in this way, the low shrinkage yarn bends along a plane on one side in the thickness direction, so the low shrinkage yarn is not visible from the other side in the thickness direction. That is, from the other side in the thickness direction, the woven fabric appears to be formed by only the high shrinkage yarn, so the aesthetics are excellent.

- the low shrinkage yarn 3 is a yarn made of material with a relatively low shrinkage ratio (i.e., it does not shrink easily) (compared to the high shrinkage yarn 2 ).
- the woven fabric 1 according to the example embodiments is such that a portion that will be the base of the woven fabric is formed by the high shrinkage yarn 2 , and the low shrinkage yarn 3 is woven in along the width direction of the base portion.
- the high shrinkage yarn 2 may be a well-known natural fiber such as cotton, hemp, or wool, or an artificial fiber such as polyester or nylon. Any of a variety of types of yarns may be used as the high shrinkage yarn 2 , as long as it has a higher shrinkage ratio than the low shrinkage yarn 3 .
- the low shrinkage yarn 3 may be made be a conductive wire of conductive metal or carbon fiber or the like.

- a finishing process including a heat treatment process
- the high shrinkage yarn 2 a i.e., the base portion of the woven fabric shrinks much more than the low shrinkage yarn 3 a does.
- This shrinkage difference causes the low shrinkage yarn 3 a to bend, but because it is held by the inductive portion 21 a, it bends in the planar direction as shown in FIG. 1B , without protruding in a direction that intersects the plane. That is, a woven fabric in which the low shrinkage yarn 3 a is bent in the planar direction following the base portion of the woven fabric that shrinks is obtained.

- the inductive portion 21 is formed by the first inductive portion 211 c and the second inductive portion 212 c.
- the constituent elements of the third example embodiment other than the restraining portion 22 c may be the same as in the second example embodiment.
- the restraining portion 22 c is a location in which the range over which displacement is allowed is smaller than it is at the inductive portion 21 ( 211 c and 212 c ). Therefore, a greater restraining force is generated by friction force and the like at a portion of the low shrinkage yarn 3 c that is positioned under the restraining portion 22 c than at a portion of the low shrinkage yarn 3 c that is positioned under the inductive portion 21 ( 211 c and 212 c ).
- the length of the restraining portion 22 c in the direction of the arrows A and B is shorter than the length of the inductive portions 211 c and 212 c in the direction of arrows A and B. That is, the size of the area where the restraining portion 22 c allows displacement of the low shrinkage yarn 3 c in the direction of arrows A and B is smaller than the size of the area where the inductive portions 211 c and 212 c allow displacement of the low shrinkage yarn 3 c in the direction of arrows A and B. Also, in this example embodiment, each restraining portion 22 c is set in generally the same position in the direction of arrows A and B.

- the low shrinkage yarn 3 c on one side of the location where it is restrained by the restraining portion 22 c bends in the direction of arrow A (a predetermined direction), and the low shrinkage yarn 3 c on the other side of the location where it is restrained by the restraining portion 22 c bends in the direction of arrow B (the direction opposite the predetermined direction), so the bending amount in the direction of arrow A on the one side of the restraining portion 22 c is substantially equivalent to the bending amount in the direction of arrow B on the other side of the restraining portion 22 c.
- the restraining portion 22 c is formed between each first inductive portion 211 c and each second inductive portion 212 c, but the restraining portion 22 c need only be formed between at least some of the first inductive portions 211 c and the second inductive portions 212 c. That is, the woven fabric 1 c according to this example embodiment may be such that the restraining portion 22 c is formed between at least some of the first inductive portions 211 c that allow displacement in the predetermined direction of the planar direction and the second inductive portions 212 c that allow displacement in the direction opposite the predetermined direction of the planar direction.

That is, the restraining portion 22 d need only be formed between at least some of the inductive portions that try to bend the low shrinkage yarn 3 d in a predetermined direction, and the inductive portions that try to bend the low shrinkage yarn 3 d in the direction opposite the predetermined direction.
- the inductive portion 21 is formed by a plurality of the first inductive portions 211 d and a plurality of the second inductive portions 212 d.
- the fourth example embodiment may be the same as the third example embodiment, aside from both the first inductive portion and the second inductive portion being formed in plurality.
- the woven fabric 1 ( 1 a to 1 d ) according to various example embodiments of the invention, in which the inductive portion 21 (i.e., the first inductive portion 211 and the second inductive portion 212 ) and the restraining portion 22 with which the low shrinkage yarn 3 engage are formed by the high shrinkage yarn 2 is described above, the intervals and the like of the inductive portion 21 and the restraining portion 22 may also be modified as appropriate. For example, as is evident when comparing a woven fabric 1 e shown in FIG. 5 with the woven fabric 1 c shown in FIG.
- the woven fabric may also be such that a low shrinkage yarn 3 e is arranged bent in short waves by making the intervals between a restraining portion 22 e, and a first inductive portion 211 e and a second inductive portion 212 e, all of which are formed by a high shrinkage yarn 2 e, even shorter.
- each of the woven fabrics described above may be a double woven fabric or a multiple woven fabric in which the low shrinkage yarn 3 forms a portion of a layer on one side in a thickness direction.
- the structure may be one in which the low shrinkage yarn 3 is arranged in a layer on the lower side in the drawing, i.e., the layer on one side in the thickness direction (the low shrinkage yarn 3 is not arranged in the layer on the upper side in the drawing).
- the low shrinkage yarn 3 that is bent along a plane (i.e., the surface) on one side (e.g., the back side) in the thickness direction is not visible from the other side (e.g., the front side) in the thickness direction. That is, from the other side in the thickness direction, the woven fabric appears to be formed by only the high shrinkage yarn 2 , so the aesthetics are excellent.
- the inductive portion 21 may be formed by a first inductive portion and a plurality of the second inductive portions, or by a plurality of first inductive portions and a second inductive portion.
- the low shrinkage yarn when the high shrinkage yarn shrinks a relatively large amount, the low shrinkage yarn is induced and bends in the planar direction by the inductive portion that is formed by high shrinkage yarn and allows displacement in a direction in the planar direction, so disconnection of the low shrinkage yarn is able to be inhibited.
- the structure is superb in that it does not greatly shrink the high shrinkage yarn locally as the related art does, so the aesthetics of the woven fabric will not be diminished.
- first weave Woven fabrics having the weaves shown in FIGS. 1 to 4 described above (hereinafter, the weaves shown in FIGS. 1 to 4 will be referred to as “first weave” to “fourth weave”, respectively) were woven using, as the high shrinkage yarn, a 167 dtex, 72 filament PET memory-twisted textured yarn for the warp yarn, and a 334 dtex, 72 filament PET memory-twisted textured yarn for the weft yarn, and as the low shrinkage yarn, a conductive yarn formed by a core yarn of carbon fiber T-300 (Toray Industries, Inc.) covered (a double covering) from two directions in a helical manner by a 334 dtex, 72 filament PET memory-twisted yarn.
- the low shrinkage yarn is woven in at a 10 mm pitch in the direction of arrows A and B before the finishing process.
- a finishing process that includes relaxing heat treatment of 90° C. ⁇ 20 minutes was applied to the woven fabric using a jet dyeing machine.
- the reason that the variation in the cycle and amplitude of the conductive yarn in the woven fabric of the second weave was smaller than that of the woven fabric of the first weave is because the inductive portions are formed in a zigzag pattern such that the first inductive portion induces the conductive yarn in the direction of arrow A and the second inductive portion induces the conductive yarn in the direction of arrow B.
- the reason that the cycle and amplitude of the conductive yarn in the woven fabrics of the third and fourth weaves were the most even is because the conductive yarn was bent with a portion restrained by the restraining portion provided between the first inductive portion and the second inductive portion as the fulcrum.
- the conductive yarn that is the low shrinkage yarn was examined for disconnections in each of the woven fabrics of the first to fourth weaves after the finishing process. No disconnections in the conductive yarn occurred in any of the woven fabrics.
- the examination for disconnections in the conductive yarn was performed by heating the conductive yarn by energizing it with 0.6 A. If there is portion where the temperature rises locally compared with another portion (i.e., if there is a portion where the temperature difference is equal to or greater than 5° C.) after one minute, or if the conductive yarn is unable to be energized, a determination of “disconnection” is made.
- a woven fabric having the weave shown in FIG. 5 described above was woven using, as low shrinkage yarn, a conductive yarn in which seven strands of SUS 316 wire having a wire diameter of 20 ⁇ m that are twisted at 1500 T/m are covered (a double covering) from two directions in a helical manner by a 334 dtex, 72 filament PET memory-twisted yarn that is twisted in the direction opposite the twisting direction of the seven strands of SUS 316 wire.
- the other conditions are the same as those in the first example.
- a woven fabric of the weave shown in FIG. 7 was woven using the same material as in the first and second examples. Simply put, with the weave shown in FIG. 7 , there is no portion corresponding to the inductive portion that allows displacement in the planar direction. Only a portion ( 911 ) corresponding to the restraining portion that allows almost no displacement in the planar direction is formed by a high shrinkage yarn ( 91 ).
- a protruding portion ( 90 x ) in which a conductive yarn ( 90 ) that is a low shrinkage yarn protrudes from the plane, as well as disconnections were confirmed to occur frequently.
- the restraining portion is a portion that acts in a favorable direction only with an inductive portion that induces the low shrinkage yarn in the planar direction.

At least a portion of the low shrinkage yarn is engaged with the inductive portion and bent in the planar direction.
Description
- The disclosure of Japanese Patent Application No. 2012-072652 filed on Mar. 28, 2012 including the specification, drawings and abstract is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The invention relates to a woven fabric having a high shrinkage yarn that has a relatively high shrinkage ratio and a low shrinkage yarn that has a relatively low shrinkage ratio.
- 2. Description of Related Art
- A woven fabric having an insulating fiber (high shrinkage yarn) and conductive wire (low shrinkage yarn), as described in Japanese Patent Application Publication No. 2010-261116 (JP 2010-261116 A) below is known. JP 2010-261116 A describes a woven fabric having a structure in which a shrinking portion is provided at a predetermined location formed by an insulating fiber. This shrinking portion tends to shrink more at the predetermined location than at other locations. Also, the conductive wire bends in a planar direction when the shrinking portion shrinks. Having the conductive wire bend in the planar direction in this way (i.e., inhibiting the conductive wire from protruding in a direction in which it intersects the plane) makes it possible to prevent the conductive wire that has a relatively low extension percentage from disconnecting.
- Because the woven fabric described in JP 2010-261116 A must have the shrinking portion that shrinks relatively easily, the aesthetics may be diminished due to the fact that this shrinkage portion shrinks more than the other portions.
- In view of this, the invention thus provides a woven fabric in which disconnection of a low shrinkage yarn is inhibited without diminishing the aesthetics.
- A first aspect of the invention relates to 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. An inductive portion that allows displacement in a planar direction is formed by the high shrinkage yarn. At least a portion of the low shrinkage yarn is engaged with the inductive portion and bent in the planar direction.
- According to this structure, when the high shrinkage yarn shrinks a relatively large amount, the inductive portion that is formed by the high shrinkage yarn and allows displacement in the planar direction causes the low shrinkage yarn to be induced in a predetermined direction of the planar direction and bend in that direction. As a result, disconnection of the low shrinkage yarn is able to be inhibited. The structure is not one that greatly shrinks the high shrinkage yarn locally as the related art does, so the aesthetics of the woven fabric will not be diminished.
- In the aspect described above, the inductive portion may include 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 may be engaged with the inductive portion and bent alternately in the predetermined direction and in the direction opposite the predetermined direction of the planar direction.
- According to this structure, the low shrinkage yarn bends alternately like a way by forming the first and second inductive portions alternately so as to allow displacement in the predetermined direction and the direction opposite the predetermined direction. That is, the structure is one in which the portions that are bent in the length direction of the low shrinkage yarn are formed substantially evenly, so the load bearing capacity and the like of the low shrinkage yarn is improved.
- Also, the woven fabric having the structure described above may also include a restraining portion that is formed by the high shrinkage yarn between at least some of 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.
- According to this structure, by forming a restraining portion in which the range over which displacement is allowed is smaller than that of the first and second inductive portions, the low shrinkage yarn is able to be inhibited from deviating from its position and the like by the restraining portion. Also, when the high shrinkage yarn shrinks, a predetermined portion of the low shrinkage yarn is held by the restraining portion, and portions of the low shrinkage yarn that are on both sides of this predetermined portion are induced by the inductive portion and bend in the planar direction. That is, with the portion of the low shrinkage yarn that is held by the restraining portion as the fulcrum, the portions on both sides of this portion are induced in the planar direction, so the effect of inhibiting the low shrinkage yarn from protruding in a direction that intersects the plane is further improved.
- A second aspect of the invention relates to a double or multiple woven fabric that includes the woven fabric described above, in which the low shrinkage yarn forms a portion of a layer on one side in a thickness direction.
- When the structure is one in which the low shrinkage yarn is arranged on a layer on a back surface side of a double or multiple woven fabric in this way, the low shrinkage yarn bends along a plane on one side in the thickness direction, so the low shrinkage yarn is not visible from the other side in the thickness direction. That is, from the other side in the thickness direction, the woven fabric appears to be formed by only the high shrinkage yarn, so the aesthetics are excellent.
- According to this structure, a woven fabric in which disconnection of a low shrinkage yarn is inhibited without diminishing the aesthetics is able to be obtained.

FIG. 7 is a plan view of a woven fabric according to a comparative example. - Example embodiments of the invention will now be described with reference to the accompanying drawings. A seat cover of a vehicle seat will be given as an example of that to which a
woven fabric 1 according to the example embodiments of the invention is applied. Hereinafter, various structures will be described in detail, with a woven fabric used as a seat cover of a vehicle seat as an example. - The
woven fabric 1 according to the example embodiments includes ahigh shrinkage yarn 2 and alow shrinkage yarn 3. Thehigh shrinkage yarn 2 is a yarn made of material with a relatively high shrinkage ratio (i.e., it shrinks easily) (compared to the low shrinkage yarn 3). Thelow shrinkage yarn 3 is a yarn made of material with a relatively low shrinkage ratio (i.e., it does not shrink easily) (compared to the high shrinkage yarn 2). Thewoven fabric 1 according to the example embodiments is such that a portion that will be the base of the woven fabric is formed by thehigh shrinkage yarn 2, and thelow shrinkage yarn 3 is woven in along the width direction of the base portion. Thehigh shrinkage yarn 2 may be a well-known natural fiber such as cotton, hemp, or wool, or an artificial fiber such as polyester or nylon. Any of a variety of types of yarns may be used as thehigh shrinkage yarn 2, as long as it has a higher shrinkage ratio than thelow shrinkage yarn 3. Also, thelow shrinkage yarn 3 may be made be a conductive wire of conductive metal or carbon fiber or the like. In the woven fabric that is used as a seat cover of a vehicle seat, the conductive wire that is arranged as thelow shrinkage yarn 3 may be used as a capacitance-type sensor for detecting whether an occupant is seated or as a heater wire that generates heat by being energized. -
FIG. 1B is a plan view of awoven fabric 1 a according to a first example embodiment of the invention (after a finishing process has been applied to the woven fabric shown inFIG. 1A ). Aninductive portion 21 a formed by ahigh shrinkage yarn 2 a is formed on thewoven fabric 1 a according to the first example embodiment. InFIGS. 1 to 5 , hatching is applied to thehigh shrinkage yarn 2 that will form the inductive portion 21, and cross-hatching is applied to the portion that will become the inductive portion 21 of thishigh shrinkage yarn 2. Theinductive portion 21 a is a portion that allows displacement in the planar direction. From another point of view, theinductive portion 21 a is a portion that prevents displacement in a direction intersecting the plane (the surface) (i.e., in a direction protruding from the plane). In this example embodiment, theinductive portion 21 a is formed by a portion of thehigh shrinkage yarn 2 a (warp yarn) that is arranged extending in the direction of arrows A and B. More specifically, there is an area of thehigh shrinkage yarn 2 a where the yarn skipping length in the direction of arrows A and B (i.e., the amount that skips over or straddles the weft yarn) is longer than it is at other areas. This location functions as theinductive portion 21 a (21). - A
low shrinkage yarn 3 a is arranged passing under thisinductive portion 21 a. That is, thelow shrinkage yarn 3 a is held by theinductive portion 21 a so that it (thelow shrinkage yarn 3 a) does not protrude in a direction that intersects the plane. When a finishing process (including a heat treatment process) such as that described in JP 2010-261116 A is applied to the woven fabric in the state shown inFIG. 1A in which thelow shrinkage yarn 3 a is arranged in a state held by theinductive portion 21 a, thehigh shrinkage yarn 2 a (i.e., the base portion of the woven fabric) shrinks much more than thelow shrinkage yarn 3 a does. This shrinkage difference causes thelow shrinkage yarn 3 a to bend, but because it is held by theinductive portion 21 a, it bends in the planar direction as shown inFIG. 1B , without protruding in a direction that intersects the plane. That is, a woven fabric in which thelow shrinkage yarn 3 a is bent in the planar direction following the base portion of the woven fabric that shrinks is obtained. -
FIG. 2B is a plan view of awoven fabric 1 b according to a second example embodiment (after a finishing process has been applied to the woven fabric shown inFIG. 2A ). With the wovenfabric 1 b according to this example embodiment, the inductive portion 21 that allows displacement in the direction of arrow A in the planar direction (hereinafter, this inductive portion 21 may also be referred to as a “firstinductive portion 211 b”) is formed alternately in the width direction with the inductive portion 21 that allows displacement in the direction of arrow B in the planar direction (hereinafter, this inductive portion 21 may also be referred to as a “secondinductive portion 212 b”). That is, with thewoven fabric 1 b according to this second example embodiment, the firstinductive portion 211 b that allows displacement in a predetermined direction of the planar direction is formed alternately with the secondinductive portion 212 b that allows displacement in the direction opposite the predetermined direction. - In this example embodiment, the first
inductive portion 211 b that allows displacement in the direction of arrow A has a portion that extends farther in the direction of arrow A than the secondinductive portion 212 b that is lined up with the firstinductive portion 211 b in the width direction. The secondinductive portion 212 b that allows displacement in the direction of arrow B has a portion that extends farther in the direction of arrow B than the firstinductive portion 211 b that is lined up with the secondinductive portion 212 b in the width direction. Also, the portion of the firstinductive portion 211 b that is lies farther in the direction of arrow B than the rest of the firstinductive portion 211 b and the portion of the secondinductive portion 212 b that lies farther in the direction of arrow A than the rest of the secondinductive portion 212 b are set overlapping each other in the direction of arrows A and B (so as to be in the same position in the direction of arrows A and B). - As shown in
FIG. 2A , thelow shrinkage yarn 3 b before the finishing process, which is generally straight in the width direction, passes through the portion where the firstinductive portion 211 b and the secondinductive portion 212 b overlap in the direction of arrows A and B. In this state, when the finishing process is applied and thehigh shrinkage yarn 2 b shrinks a relatively large amount, the portion of thelow shrinkage yarn 3 b that passes under the firstinductive portion 211 b bends in the direction of arrow A because displacement in the direction of arrow A is allowed. Meanwhile, the portion of thelow shrinkage yarn 3 b that passes under the secondinductive portion 212 b bends in the direction of arrow B in the planar direction because displacement in the direction of arrow B is allowed. In this way, thewoven fabric 1 b shown inFIG. 2B in which thelow shrinkage yarn 3 b is arranged in a wavy shape that alternately bends in the directions of arrows A and B in the planar direction is obtained by the base portion of the woven fabric that is formed by thehigh shrinkage yarn 2 b and has undergone the finishing process shrinking a relatively large amount. - In this second example embodiment, one first
inductive portion 211 b that allows displacement in the direction of arrow A (a predetermined direction) is formed alternately with one secondinductive portion 212 b that allows displacement in the direction of arrow B (the direction opposite the predetermined direction). Alternatively, however, the structure may also be one in which a plurality of the firstinductive portions 211 b are formed alternately with a plurality of the secondinductive portions 212 b, such as a structure in which two of the firstinductive portions 211 b are formed alternately with two of the secondinductive portions 212 b. Also, the structure may be one in which one firstinductive portion 211 b or one secondinductive portion 212 b is formed alternately with a plurality of the secondinductive portions 212 b or the firstinductive portions 211 b. - Furthermore, in the example embodiment described above, the amount of displacement allowed by the first inductive portion in the direction of arrow A need only be at least greater than the amount of displacement allowed by the first inductive portion in the direction of arrow B, and the amount that displacement allowed by the second inductive portion in the direction of arrow B need only be at least greater than the amount of displacement allowed by the second inductive portion in the direction of arrow A. In other words, the yarn skipping amount in the direction of arrow A (the predetermined direction) from the position where the low shrinkage yarn is engaged at the first inductive portion need only be greater than the yarn skipping amount in the direction of arrow B (the direction opposite the predetermined direction) from the position where the low shrinkage yarn is engaged at the first inductive portion, and the yarn skipping amount in the direction of arrow B (the direction opposite the predetermined direction) from the position where the low shrinkage yarn is engaged at the second inductive portion need only be greater than the yarn skipping amount in the direction of arrow A (the predetermined direction) from the position where the low shrinkage yarn is engaged at the second inductive portion. In other words, it is not necessary to form the first inductive portion so as not to allow any displacement in the direction of arrow B, and form the second inductive portion so as not to allow any displacement in the direction of arrow A.
-
FIG. 3B is a plan view of awoven fabric 1 c according to a third example embodiment of the invention (after a finishing process has been applied to the woven fabric shown inFIG. 3A ). Thewoven fabric 1 c according to this example embodiment is such that a firstinductive portion 211 c that allows displacement in the direction of arrow A in the planar direction is formed alternately in the width direction with a secondinductive portion 212 c that allows displacement in the direction of arrow B in the planar direction, and a restrainingportion 22 c is formed between the firstinductive portion 211 c and the secondinductive portion 212 c in the width direction. In this third example embodiment, the inductive portion 21 is formed by the firstinductive portion 211 c and the secondinductive portion 212 c. The constituent elements of the third example embodiment other than the restrainingportion 22 c may be the same as in the second example embodiment. - The restraining
portion 22 c is a location in which the range over which displacement is allowed is smaller than it is at the inductive portion 21 (211 c and 212 c). Therefore, a greater restraining force is generated by friction force and the like at a portion of thelow shrinkage yarn 3 c that is positioned under the restrainingportion 22 c than at a portion of thelow shrinkage yarn 3 c that is positioned under the inductive portion 21 (211 c and 212 c). With a structure in which theinductive portions portion 22 c in the direction of the arrows A and B is shorter than the length of theinductive portions portion 22 c allows displacement of thelow shrinkage yarn 3 c in the direction of arrows A and B is smaller than the size of the area where theinductive portions low shrinkage yarn 3 c in the direction of arrows A and B. Also, in this example embodiment, each restrainingportion 22 c is set in generally the same position in the direction of arrows A and B. - As shown in
FIG. 3A , thelow shrinkage yarn 3 c before the finishing process, which is generally straight in the width direction, passes under the firstinductive portion 211 c, the secondinductive portion 212 c, and the restrainingportion 22 c. In this state, when the finishing process is applied and thehigh shrinkage yarn 2 c shrinks a relatively large amount, the portion of thelow shrinkage yarn 3 c that passes under the firstinductive portion 211 c bends in the direction of arrow A in the planar direction and the portion of thelow shrinkage yarn 3 c that passes under the secondinductive portion 212 c bends in the direction of arrow B in the planar direction, with the location where it is restrained by the restrainingportion 22 c as the fulcrum. In particular, in this example embodiment, thelow shrinkage yarn 3 c on one side of the location where it is restrained by the restrainingportion 22 c bends in the direction of arrow A (a predetermined direction), and thelow shrinkage yarn 3 c on the other side of the location where it is restrained by the restrainingportion 22 c bends in the direction of arrow B (the direction opposite the predetermined direction), so the bending amount in the direction of arrow A on the one side of the restrainingportion 22 c is substantially equivalent to the bending amount in the direction of arrow B on the other side of the restrainingportion 22 c. - In the third example embodiment, the restraining
portion 22 c is formed between each firstinductive portion 211 c and each secondinductive portion 212 c, but the restrainingportion 22 c need only be formed between at least some of the firstinductive portions 211 c and the secondinductive portions 212 c. That is, thewoven fabric 1 c according to this example embodiment may be such that the restrainingportion 22 c is formed between at least some of the firstinductive portions 211 c that allow displacement in the predetermined direction of the planar direction and the secondinductive portions 212 c that allow displacement in the direction opposite the predetermined direction of the planar direction. - Also,
FIG. 4 is a plan view of awoven fabric 1 d according to a fourth example embodiment of the invention. In this fourth example embodiment, a plurality of firstinductive portions 211 d are formed alternately with a plurality of secondinductive portions 212 d, and a restrainingportion 22 d is formed between at least some of the plurality of the firstinductive portions 211 d and the plurality of the secondinductive portions 212 d. That is, the restrainingportion 22 d need only be formed between at least some of the inductive portions that try to bend thelow shrinkage yarn 3 d in a predetermined direction, and the inductive portions that try to bend thelow shrinkage yarn 3 d in the direction opposite the predetermined direction. In the fourth example embodiment, the inductive portion 21 is formed by a plurality of the firstinductive portions 211 d and a plurality of the secondinductive portions 212 d. The fourth example embodiment may be the same as the third example embodiment, aside from both the first inductive portion and the second inductive portion being formed in plurality. - While the woven fabric 1 (1 a to 1 d) according to various example embodiments of the invention, in which the inductive portion 21 (i.e., the first inductive portion 211 and the second inductive portion 212) and the restraining portion 22 with which the
low shrinkage yarn 3 engage are formed by thehigh shrinkage yarn 2 is described above, the intervals and the like of the inductive portion 21 and the restraining portion 22 may also be modified as appropriate. For example, as is evident when comparing awoven fabric 1 e shown inFIG. 5 with thewoven fabric 1 c shown inFIG. 3 , the woven fabric may also be such that alow shrinkage yarn 3 e is arranged bent in short waves by making the intervals between a restrainingportion 22 e, and a firstinductive portion 211 e and a secondinductive portion 212 e, all of which are formed by ahigh shrinkage yarn 2 e, even shorter. - Also, each of the woven fabrics described above may be a double woven fabric or a multiple woven fabric in which the
low shrinkage yarn 3 forms a portion of a layer on one side in a thickness direction. For example, with a double woven fabric, as shown inFIG. 6 , the structure may be one in which thelow shrinkage yarn 3 is arranged in a layer on the lower side in the drawing, i.e., the layer on one side in the thickness direction (thelow shrinkage yarn 3 is not arranged in the layer on the upper side in the drawing). Accordingly, thelow shrinkage yarn 3 that is bent along a plane (i.e., the surface) on one side (e.g., the back side) in the thickness direction is not visible from the other side (e.g., the front side) in the thickness direction. That is, from the other side in the thickness direction, the woven fabric appears to be formed by only thehigh shrinkage yarn 2, so the aesthetics are excellent. Further, the inductive portion 21 may be formed by a first inductive portion and a plurality of the second inductive portions, or by a plurality of first inductive portions and a second inductive portion. - With the woven fabric according to the example embodiments described above, when the high shrinkage yarn shrinks a relatively large amount, the low shrinkage yarn is induced and bends in the planar direction by the inductive portion that is formed by high shrinkage yarn and allows displacement in a direction in the planar direction, so disconnection of the low shrinkage yarn is able to be inhibited. In these example embodiments, the structure is superb in that it does not greatly shrink the high shrinkage yarn locally as the related art does, so the aesthetics of the woven fabric will not be diminished.
- Hereinafter, the invention will be described with reference to specific examples. However, the invention is not intended to be limited by the examples below.
- A first example will first be described. Woven fabrics having the weaves shown in
FIGS. 1 to 4 described above (hereinafter, the weaves shown inFIGS. 1 to 4 will be referred to as “first weave” to “fourth weave”, respectively) were woven using, as the high shrinkage yarn, a 167 dtex, 72 filament PET memory-twisted textured yarn for the warp yarn, and a 334 dtex, 72 filament PET memory-twisted textured yarn for the weft yarn, and as the low shrinkage yarn, a conductive yarn formed by a core yarn of carbon fiber T-300 (Toray Industries, Inc.) covered (a double covering) from two directions in a helical manner by a 334 dtex, 72 filament PET memory-twisted yarn. The weaving density before the finishing process is warp/weft=68 strands/100 strands per 25.4 mm square. The low shrinkage yarn is woven in at a 10 mm pitch in the direction of arrows A and B before the finishing process. - Then a finishing process that includes relaxing heat treatment of 90° C.×20 minutes was applied to the woven fabric using a jet dyeing machine. The weaving density after the finishing process was warp/weft=233 strands/108 strands per 25.4 mm square, so the base portion of the woven fabric shrunk 39% compared to what it was before the finishing process.
- Upon checking the conductive yarn that is the low shrinkage yarn of the woven fabrics of the first to fourth weaves after this finishing process, it was confirmed that the conductive yarn was bent in a wavy shape in the planar direction with all of the woven fabrics of the first to fourth weaves. However, when looking at the cycle and amplitude of the waves, the woven fabric of the first weave was the most varied, and the woven fabrics of the third and fourth weaves where the most even (had the prettiest waves). It is thought that the reason for the large variation in the cycle and amplitude of the conductive yarn in the woven fabric of the first weave is because the positions of all of the inductive portions in the direction of arrows A and B are the same. Also, it is thought that the reason that the variation in the cycle and amplitude of the conductive yarn in the woven fabric of the second weave was smaller than that of the woven fabric of the first weave is because the inductive portions are formed in a zigzag pattern such that the first inductive portion induces the conductive yarn in the direction of arrow A and the second inductive portion induces the conductive yarn in the direction of arrow B. Moreover, it is thought that the reason that the cycle and amplitude of the conductive yarn in the woven fabrics of the third and fourth weaves were the most even is because the conductive yarn was bent with a portion restrained by the restraining portion provided between the first inductive portion and the second inductive portion as the fulcrum.
- Also, the conductive yarn that is the low shrinkage yarn was examined for disconnections in each of the woven fabrics of the first to fourth weaves after the finishing process. No disconnections in the conductive yarn occurred in any of the woven fabrics. The examination for disconnections in the conductive yarn was performed by heating the conductive yarn by energizing it with 0.6 A. If there is portion where the temperature rises locally compared with another portion (i.e., if there is a portion where the temperature difference is equal to or greater than 5° C.) after one minute, or if the conductive yarn is unable to be energized, a determination of “disconnection” is made.
- Next, a second example will be described. A woven fabric having the weave shown in
FIG. 5 described above (hereinafter, referred to as “fifth weave”) was woven using, as low shrinkage yarn, a conductive yarn in which seven strands of SUS 316 wire having a wire diameter of 20 μm that are twisted at 1500 T/m are covered (a double covering) from two directions in a helical manner by a 334 dtex, 72 filament PET memory-twisted yarn that is twisted in the direction opposite the twisting direction of the seven strands of SUS 316 wire. The other conditions are the same as those in the first example. - Upon checking the woven fabric after the finishing process, it was confirmed that the conductive yarn was bent in a wavy shape in the planar direction. Also, the cycle and amplitude of the waves was constant.
- Further, there were no disconnections in the conductive yarn that is the low shrinkage yarn of the woven fabric after the finishing process.
- Next, a comparative example will be described. A woven fabric of the weave shown in
FIG. 7 was woven using the same material as in the first and second examples. Simply put, with the weave shown inFIG. 7 , there is no portion corresponding to the inductive portion that allows displacement in the planar direction. Only a portion (911) corresponding to the restraining portion that allows almost no displacement in the planar direction is formed by a high shrinkage yarn (91). - With the woven fabric according to the comparative example after the finishing process, bending (i.e., a protruding portion (90 x)), in which a conductive yarn (90) that is a low shrinkage yarn protrudes from the plane, as well as disconnections were confirmed to occur frequently. It was recognized that the restraining portion is a portion that acts in a favorable direction only with an inductive portion that induces the low shrinkage yarn in the planar direction.
- While the invention has been described with reference to example embodiments thereof, it is to be understood that the invention is not limited to the described embodiments or constructions. To the contrary, the invention is intended to cover various modifications and equivalent arrangements. In addition, while the various elements of the example embodiments are shown in various combinations and configurations, other combinations and configurations, including more, less or only a single element, are also within the scope of the invention.
