Description

  The present invention relates to a ventilated tissue woven fabric and a double woven fabric that form a bundled fabric while using a small amount of fibers. The present invention also relates to an air-permeable tissue fabric and a double-woven fabric fabric that can be used as a warming fabric suitable for use in foot warmers, laps, and shawls when silk is used as the fiber.

  It is said that it is necessary to keep the body at a certain temperature in order to get a good night's sleep. Especially in the cold winter, foot warmers such as electric rods may be used to warm the feet that cool. Therefore, the present applicant has proposed a warming fabric that can be compactly stored, can warm the human body without using a heat source such as electricity, and is comfortable and harmless to the human body (for example, the present applicant). (See Patent Document 1).

Further, Patent Document 2 proposes a blister fabric for interior using an air-permeable organization. In such bulging fabrics for interior use, high shrinkage yarns and low shrinkage yarns are used in a 1: 1 arrangement for both warp and weft yarns. For the surface structure, a patterned fabric having an air-permeable structure in which high-shrinkage yarns are the back structure of the air-permeable structure is used.

  By the way, as a result of intensive research by the inventor, it has been found that a woven fabric structure capable of effectively forming a pleated ridge is required for the warming fabric. In addition, when a pleated ridge is formed in this way, a fabric structure having a relatively high porosity can be obtained with a small amount of fibers. Therefore, a fabric for obtaining a fabric structure having such a property has been required. In the ventilated structure of Patent Document 2, high shrinkage yarns and low shrinkage yarns are used in a 1: 1 arrangement for both warp and weft yarns, and the blisters formed are high shrinkage yarns and low shrinkage yarns. There is a problem that it is determined by the arrangement and is not suitable as a pleated fold of a warming fabric.

  This invention solves the subject mentioned above, and it aims at providing the manufacturing method of the ventilation structure textile fabric which can obtain the textile structure which has a comparatively high porosity with a small amount of fibers, and an ventilation structure textile fabric. . Another object of the present invention is to provide a double woven fabric and a method for producing the double woven fabric that can obtain a fabric structure having a relatively high porosity with a small amount of fibers.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a woven fabric structure of a double-tissue air-permeable tissue fabric according to an embodiment of the present invention. As shown in FIG. 1, the ventilated fabric has a double structure having a first fabric 10 and a second fabric 20, and the first fabric 10 and the first fabric 10 at a first interval p1 in the warp direction or the weft direction. This is a woven fabric having an air-permeable structure in which the front and back surfaces of the second fabric 20 are crossed. Here, although the case where the first fabric 10 and the second fabric 20 are plain weaves is shown, a twill weave or satin weave which is a three-layer structure of the fabric may be used, or one may be plain weave and the other may be twill or satin weave. . Although the 1st space | interval p1 can be suitably determined as a ventilation structure | tissue, in the use for clothing, it is often about 2 cm-10 cm.

  Here, the high-shrinkage yarn 30 is provided on the lining of the ventilated tissue, but the high-shrinkage yarn 30 may be provided on the outer fabric side of the ventilated tissue, or may be provided on both the lining and the outer fabric. good. The high shrinkage yarn 30 is provided on the lining side of the ventilated tissue at the second interval p2. Although the 2nd space | interval p2 can be determined suitably, for example, one or two high shrinkage yarns 30 are used for 10 to 100 fibers constituting the woven fabric. As the high shrinkage yarn 30, nylon, polyester, strong twist fiber, or the like is used. As fibers constituting the woven fabric, natural fibers, synthetic fibers, regenerated fibers, and the like may be used. For example, silk or cotton can be used as the natural fiber. Synthetic fibers are not limited to those made of hydrocarbon compounds, and various materials such as glass fibers, carbon fibers, and metal fibers can be used.

  In the woven fabric structure configured as described above, the front and back surfaces of the first fabric 10 and the second fabric 20 are crossed at the first interval p1, so that a longitudinal or wefted ventilation structure is woven. Since the high shrinkage yarn 30 is used at a second interval p2 in a direction orthogonal to the direction in which the front and back surfaces of the first fabric 10 and the second fabric 20 intersect, it is compared with an air-flowing structure intersecting in one direction. In addition, there is a grouping, and by appropriately selecting the shrinkage ratio of the high shrinkage yarn 30, it is possible to flexibly determine the bulging state of the ventilated tissue as compared with the ventilated tissue intersecting in the two directions of the weft.

  FIG. 2 is a configuration diagram showing a fabric structure of an air-woven fabric with a weft contraction (weft swelling) according to the first embodiment of the present invention, and shows a plain weave case. 2A is a plan view seen from the lining side, (B1) is a cross-sectional view in the weft direction of a normal fiber along B1-B1 in FIG. 2 (A), and (B2) is B2-B2 in FIG. 2 (A). FIG. 4C is a cross-sectional view in the weft direction of the high shrinkage yarn taken along the line A, and FIG. Note that the plan view shown in FIG. 2A shows the lining-side tissue and the front-side tissue overlaps with the lining-side tissue, but the lining-side tissue and the front-side organization Can be expressed by shifting the yarn by 1/2 yarn based on the repeating unit of plain weave. The organization notation on the lining side in this plan view is not limited to FIG. 2, and is the same in FIGS. 5, 7, 9 and 11.

  As shown in FIG. 2 (B1), a combination of warp and weft is repeated in four directions of section I, section II, section III, and section IV in the weft direction. The section I has a two-layer structure of the first fabric 12 and the second fabric 22. The first fabric 12 is woven through the first wefts 51a and 51b while crossing the first warp 41 and the second warp 42. The second fabric 22 is woven through the second weft yarns 52a and 52b while the third warp yarn 43 and the fourth warp yarn 44 intersect each other. Since they are plain weaves, the first weft yarns 51a and 51b and the second weft yarns 52a and 52b each have two repeating units.

  The section II and the section IV show the longitudinal ventilation structure 80, and appear alternately when the first fabric 12 and the second fabric 22 are crossed at the third interval p3 in the weft direction. In the section III, the first fabric 12 and the second fabric 22 are simply reversed to the section I to form a third fabric 12a and a fourth fabric 22a. That is, as shown in FIG. 2 (B1), the third fabric 12a is woven through the first wefts 51a and 51b while the first warp 41 and the second warp 42 are crossed. The fourth fabric 22a is woven through the second weft yarns 52a and 52b while the third warp yarn 43 and the fourth warp yarn 44 intersect each other. In the section III, the first wefts 51a and 51b are formed with a two-layer structure of the first fabric 12 and the second fabric 22 as “a longitudinal ventilation structure intersecting the weft direction at a third interval”. And the second weft yarns 52a and 52b may be reversed to the section I to form the third fabric 12a and the fourth fabric 22a.

  The high-shrinkage yarns 32a and 32b have a high shrinkage rate compared to the fibers constituting the weaving tissue woven fabric having a shrinkage in the weft direction. Used at an interval p4 of 4. Here, since the high shrinkage yarns 32a and 32b are used as the weft yarn, two weft yarns are put adjacent to each other so as to be integrated with the fabric structure. The fibers constituting the weaving tissue fabric contracted in the weft direction include the first warp 41, the second warp 42, the third warp 43, the fourth warp 44, the first wefts 51a, 51b and the second Weft yarns 52a and 52b are included. The fourth interval p4 can be determined independently of the third interval p3. Typically, if the fourth interval p4 is substantially the same as the third interval p3, a blister with a plain weave pattern is obtained. As shown in FIG. 2 (B2), at the place where the high shrinkage yarns 32a and 32b are used as weft yarns, the position passing through the warp-direction ventilation structure 80 on the lining side or the outer surface side where the high shrinkage yarns 32a and 32b are located. Thus, the high shrinkage yarns 32a and 32b are woven so as to communicate with the warp yarn of the other side of the fabric. At this time, the normal fibers adjacent to the high-shrinkage yarns 32a and 32b are woven so as to intersect with the warp yarns on the lining side or the outer side of the original position.

  Next, a method of weaving such a weft-shrinking air-woven fabric will be described. FIG. 3 is a perspective view showing a structure of a loom for weaving a double-tissue air-woven fabric. In this embodiment, a combination of looms for plain weaving is shown. The heddle frames 100 and 102 are rod frames for feeding out the first warp yarn 41 and the second warp yarn 42, and have a predetermined number of steel wires called healds (綜 絖) 101. The warp yarns necessary for weaving the first fabric 12 are the first warp yarn 41 and the second warp yarn 42, and a predetermined number corresponding to the width of the first fabric 12 is synchronized so that the thread of the heald 101 is threaded. It is drawn out in the warp direction through the hole. Since the heddle frames 100 and 102 perform an opening movement, the weft 51 is moved in the weft direction at the position of the weft insertion 120 in synchronization with this, and the first fabric 12 is woven. In addition, the 1st warp 41 and the 2nd warp 42 are wound by the delivery rolls 110 and 112, respectively.

  The heddle frames 104 and 106 are hook frames for feeding out the third warp thread 43 and the fourth warp thread 44, and have a predetermined number of steel wires called healds. The warp yarns necessary for weaving the second fabric 22 are the third warp yarn 43 and the fourth warp yarn 44, and through a threaded hole of the heald synchronously with a predetermined number corresponding to the width of the second fabric 22, It is paid out in the longitudinal direction. Since the hold frames 104 and 106 perform an opening movement, the weft 52 is moved in the weft direction at the position of the weft insert 122 in synchronism with this, and the second fabric 22 is woven. In addition, the 3rd warp 43 and the 4th warp 44 are wound by the delivery rolls 114 and 116, respectively.

  Here, since the ventilated tissue fabric has the warp-direction ventilated tissue 80, it is necessary to cross the first fabric 12 and the second fabric 22 at the third interval p3 in the weft direction. Therefore, the heald frames 100 and 102 and the heald frames 104 and 106 are moved and aligned so as to form the transversal ventilation structure 80, and the yarn wound around the delivery rolls 110 and 112 and the delivery rolls 114 and 116. Consider the type of. Since the high shrinkage yarns 32a and 32b are used at the fourth interval p4 as weft yarns on the lining side of the ventilated tissue, the high shrinkage yarns 32a and 32b are wefted with a shuttle at the fourth interval p4 instead of the weft yarns 51 and 52. Move in the direction. Then, the punching is performed with the punching 120 at an appropriate timing, and the weft yarn interval is appropriately determined and woven.

  In the embodiment of FIG. 3, the first warp 41 and the second warp 42, the third warp 43 and the fourth warp 44 are sent out by two sets of rolls 110 and 112 and the feed rolls 114 and 116, respectively. Although the case where it uses is shown, the 1st-4th warp threads 41, 42, 43, and 44 may be let out by a set of rolls, and the four heald frames 100, 102, 104, and 106 may be used. .

  FIG. 4 is a flowchart showing a method for manufacturing a weave fabric with a shrinkage in the transverse direction. First, the first fabric 12 is woven through the first wefts 51a and 51b while crossing the first warp 41 and the second warp 42 (step S102). Further, the second fabric 22 is woven through the second weft yarns 52a and 52b while the third warp yarn 43 and the fourth warp yarn 44 intersect each other (step S104). Then, it is determined whether the first weft yarns 51a, 51b and the second weft yarns 52a, 52b have advanced the third distance p3 in the weft direction (step S106). If No, the weft yarn is moved in the weft direction by the shuttle as it is. Then, the process proceeds to step S110. If Yes in step S106, the first fabric 12 and the second fabric 22 are intersected in the weft direction at a third interval p3 to form the longitudinal direction ventilation tissue 80 (step S108). Then, it is determined whether a width to be woven between the first fabric 12 and the second fabric 22 is secured (step S110), and if no, the process returns to S102.

  If Yes in step S110, it is determined whether the width to be woven has been secured (step S112). If Yes, the process ends. If “No” in step S112, it is determined whether the fourth interval p4 has been advanced in the warp direction from the start end or the latest high-shrinkage yarns 32a and 32b (step S114). If Yes in step S114, the high shrinkage yarns 32a and 32b are set as the next weft yarn (step S116), and the process returns to S102. If No in step S114, the first weft 51a, 51b or the second weft 52a, 52b is set as the next weft (step S118), and the process returns to S102.

  FIG. 5 is a structural diagram showing a fabric structure of a warped tissue fabric of warp direction shrinkage (warp swelling) showing a second embodiment of the present invention, and shows a plain weave case. 5A is a plan view seen from the lining side, FIG. 5B is a cross-sectional view in the weft direction along BB in FIG. 5A, and FIG. 5C is along C1-C1 in FIG. A warp direction sectional view of a normal fiber, (C2) is a weft direction sectional view of a high shrinkage yarn along C2-C2 of FIG. 5 (A).

  As shown in FIG. 5 (C1), the combination of warp and weft is repeated in the warp direction of section V, section VI, section VII, and section VIII. The section V has a two-layer structure of the first fabric 14 and the second fabric 24. The first fabric 14 is woven through the first weft yarns 71a and 71b while the first warp yarn 61 and the second warp yarn 62 intersect each other. The second fabric 24 is woven through the second weft yarns 72a and 72b while the third warp yarn 63 and the fourth warp yarn 64 intersect each other. Since it is a plain weave, the first weft yarns 71a and 71b and the second weft yarns 72a and 72b each have two repeating units.

  The section VI and the section VIII indicate the weft direction ventilation structure 90, and appear alternately when the first fabric 14 and the second fabric 24 intersect at the fifth interval p5 in the warp direction. In the section VII, the first cloth 14 and the second cloth 24 are simply reversed to the section V to form a fifth cloth 14a and a sixth cloth 24a. That is, as shown in FIG. 5C1, the fifth fabric 14a is woven through the first weft yarns 71a and 71b while the first warp yarn 61 and the second warp yarn 62 intersect each other. The sixth fabric 24a is woven through the second weft yarns 72a and 72b while the third warp yarn 63 and the fourth warp yarn 64 intersect each other. In the section VII, the first wefts 71a and 71b are defined as a weft-direction ventilation structure in which the two-layer structure of the first fabric 14 and the second fabric 24 is intersected at the fifth interval in the warp direction. And the second weft yarns 72a and 72b may be reversed to the section V to form the fifth fabric 14a and the sixth fabric 24a.

  The high-shrinkage yarn 34 has a high shrinkage rate compared with the fibers constituting the warp-direction-woven fabric with a shrinkage in the warp direction. The interval p6 is used. Here, the high shrinkage yarn 34 is used as the warp yarn, and in the case of the warp yarn, even a single high shrinkage yarn 34 is sufficient on the fabric structure since it is integrated with the fabric structure, but the shrinkage is further increased. If you do, you may put more than one. The fibers constituting the warp-direction compressed air-woven fabric include the first warp 61, the second warp 62, the third warp 63, the fourth warp 64, the first wefts 71a, 71b and the second. Of weft yarns 72a and 72b.

  The sixth interval p6 can be determined independently of the fifth interval p5. Typically, when the interval is substantially the same as the fifth interval p5, a bulge having a large plain weave pattern is obtained. In the place where the high shrinkage yarn 34 is used as the weft, as shown in FIG. 5 (C2), on the lining side or the outer side where the high shrinkage yarn 34 is located, the other side at the position passing through the weft direction ventilation structure 90. A high shrinkage yarn 34 is woven to intersect the weft of the tissue. At this time, the normal fibers adjacent to the high shrinkage yarns 34 are woven so as to intersect with the weft yarns on the lining side or the outer surface side where they are originally located.

  Next, a method for weaving such an air-woven fabric having a shrinkage in the vertical direction will be described. FIG. 6 is a flowchart showing a method for producing a warp directionally shortened ventilated tissue fabric. First, as the warp yarn, the high shrinkage yarn 34 is set at the sixth interval p6, and the fibers constituting the fabric are set (step S200). Next, the first fabric 14 is woven through the first wefts 71a and 71b while crossing the first warp 61 and the second warp 62 (step S202). Further, the second fabric 24 is woven through the second weft yarns 72a and 72b while the third warp yarn 63 and the fourth warp yarn 64 intersect each other (step S204).

  Next, it is determined whether the first weft yarns 71a, 71b and the second weft yarns 72a, 72b have advanced the fifth interval p5 in the weft direction (step S206). If No, the weft yarn is moved in the weft direction by the shuttle as it is. Then, the process proceeds to step S210. If Yes in step S206, the first fabric 14 and the second fabric 24 are intersected in the weft direction at the fifth interval p5 to form the weft direction ventilation structure 90 (step S208). Then, it is determined whether a width to be woven between the first fabric 14 and the second fabric 24 can be secured (step S210). If No, the process returns to S202. If Yes in step S210, it is determined whether the width to be woven has been secured (step S212). If Yes, the process ends. If No in step S212, the first wefts 71a and 71b and the second wefts 72a and 72b are set as the next wefts (step S214), and the process returns to S202.

  In addition, as said 1st and 2nd embodiment, although the case where both the 1st fabric and the 2nd fabric were plain weave was shown, this invention is not limited to this. For example, the first fabric and the second fabric may both be twill. Twill weave is one of the three woven fabrics of woven fabrics consisting of three warp yarns and three weft yarns, but there are various twill weaves composed of four or more warp weft yarns, which are also called five-blade or eight-blade. The first fabric and the second fabric may both be satin weave. Since satin weave has a small number of yarn bends, the surface is smooth and the yarn density is high, and the fabric is thick, soft and glossy. In the satin weaving, the crossing points are not adjacent to each other, and are at regular intervals.

  Furthermore, as the first fabric and the second fabric, one may be plain weave and the other may be twill or satin weave. A plain weave is a structure in which warps and wefts float up and down alternately, and has many crossing points and is thin and strong against friction. Plain weaving is the basic structure of a woven fabric that can be woven from two warp yarns and two weft yarns, so that the structure of the loom is simple and the production efficiency of the fabric is increased. In view of this, in the double-structured air-woven fabric, it is possible to give a composite property of plain weave, twill weave, and satin weave by using an appropriate structure from the three primaries of the fabric.

  In this case, in the description of FIG. 2, the first warp 41, the second warp 42, the third warp 43, the fourth warp 44, the first wefts 51a and 51b, and the second wefts 52a and 52b are used. Use to explain plain weave. In the description of FIG. 5, the first warp 61, the second warp 62, the third warp 63, the fourth warp 64, the first wefts 71a and 71b, and the second wefts 72a and 72b are used. Explains plain weaving. In the twill weave, we read as follows in the explanation of plain weave. When the first fabric is a twill weave, the first warp is one yarn constituting the twill, and the second warp is two or more remaining yarns constituting the twill. The first weft is a predetermined number of yarns that intersect the first warp and the second warp to form a diagonal line. Further, when the second fabric is a twill weave, the third warp is one yarn constituting the twill, and the fourth warp is two or more remaining yarns constituting the twill. In addition, the second weft yarn is a predetermined number of yarns that intersect with the third warp yarn and the fourth warp yarn to form a diagonal line.

  In Shuko weaving, we read as follows in the explanation of plain weaving. When the first fabric is satin weave, the first warp is one yarn constituting the satin weave, and the second warp is four or more remaining yarns constituting the satin weave. At the same time, the first weft yarn is a predetermined number of yarns that intersect with the first warp yarn or the second warp yarn with a predetermined number of jumps. When the second fabric is a satin weave, the third warp is one yarn constituting the satin weave, and the fourth warp is four or more remaining parts constituting the satin weave. In addition to being a yarn, the second weft yarn is a predetermined number of yarns that intersect with the third warp yarn or the fourth warp yarn with a predetermined number of jumps.

  FIG. 7 is a structural diagram showing a weave structure of a double woven fabric with weft shrinkage (weft swelling) showing a third embodiment of the present invention, and shows a plain weave case. 7A is a plan view seen from the lining side, FIG. 7B is a cross-sectional view in the weft direction of a normal fiber along B1-B1 in FIG. 7A, and FIG. 7B is B2-B2 in FIG. FIG. 8C is a cross-sectional view in the weft direction of the high shrinkage yarn taken along the line A, and FIG.

  As shown in FIG. 7 (B1), the combination of warp and weft is repeated in two sections, section IX and section X in the weft direction. The section IX has a two-layer structure of the first fabric 16 and the second fabric 26. The first fabric 16 is woven through the first weft yarns 151a and 151b while the first warp yarn 141 and the second warp yarn 142 cross each other. The second fabric 26 is woven through the second weft yarns 152a and 152b while crossing the third warp yarn 143 and the fourth warp yarn 144. Since it is a plain weave, the first weft threads 151a and 151b and the second weft threads 152a and 152b each have two repeat units. The section X indicates the warp-direction connected structure 82, and the first weft 151b is connected to the seventh cloth p7 in order to connect the first fabric 16 and the second fabric 26 in the weft direction with the seventh interval p7. Are intersected with the third warp 143 or the fourth warp 144 of the second fabric 26 (see FIGS. 7B1 and 7B2).

  The high shrinkage yarns 36a and 36b have a high shrinkage rate compared to the fibers constituting the double woven fabric contracted in the weft direction, and as the weft yarn on at least one side of the double woven fabric, which becomes the lining or outer surface side, Used at the eighth interval p8. Here, since the high shrinkage yarns 36a and 36b are used as the weft yarn, two weft yarns are put adjacent to each other so as to be integrated with the fabric structure. The fibers constituting the double woven fabric contracted in the weft direction include the first warp yarn 141, the second warp yarn 142, the third warp yarn 143, the fourth warp yarn 144, the first weft yarns 151a, 151b, and the second Weft yarns 152a and 152b are included. The eighth interval p8 can be determined independently of the seventh interval p7. Typically, if the eighth interval p8 is substantially the same as the seventh interval p7, a bulge having a large plain weave pattern is obtained.

  FIG. 8 is a flowchart showing a method of manufacturing a double woven fabric with a shrinkage in the transverse direction. First, the first fabric 16 is woven through the first wefts 151a and 151b while the first warp 141 and the second warp 142 are crossed (step S302). Further, the second fabric 26 is woven through the second weft yarns 152a and 152b while the third warp yarn 143 and the fourth warp yarn 144 intersect each other (step S304). Then, it is determined whether the first wefts 151a and 151b and the second wefts 152a and 152b have advanced the seventh interval p7 in the weft direction (step S306). If no, the weft is moved in the weft direction by the shuttle as it is. Then, the process proceeds to step S310. If Yes in step S306, the first fabric 16 and the second fabric 26 are connected at the seventh interval p7 in the weft direction to form the warp direction connected tissue 82 (step S308). Then, it is determined whether the width to be woven between the first fabric 16 and the second fabric 26 is secured (step S310), and if No, the process returns to S302.

  If Yes in step S310, it is determined whether the width to be woven has been secured (step S312). If Yes, the process ends. If “No” in step S312, it is determined whether the eighth interval p8 has been advanced in the warp direction from the start end or the latest highly contracted yarns 36a, 36b (step S314). If Yes in step S314, the high shrink yarns 36a and 36b are set as the next weft yarn (step S316), and the flow returns to S302. If No in step S314, the first wefts 151a and 151b or the second wefts 152a and 152b are set as the next weft (step S318), and the process returns to S302.

  FIG. 9 is a structural view showing a fabric structure of a double woven fabric of warp direction shrinkage (warp swelling) showing a fourth embodiment of the present invention, and shows a plain weave case. 9A is a plan view seen from the lining side, FIG. 9B is a cross-sectional view in the weft direction along BB in FIG. 9A, and FIG. 9C is along C1-C1 in FIG. A warp direction sectional view of a normal fiber, (C2) is a weft direction sectional view of a high shrinkage yarn along C2-C2 of FIG.

  As shown in FIG. 9 (C1), the section XI and the section XII are repeated in the warp direction by a combination of warp and weft. The section XI has a two-layer structure of the first fabric 18 and the second fabric 28. The first fabric 18 is woven through the first weft yarns 171a and 171b while the first warp yarn 161 and the second warp yarn 162 intersect each other. The second fabric 28 is woven through the second weft yarns 172a and 172b while the third warp yarn 163 and the fourth warp yarn 164 cross each other. Since it is a plain weave, the first weft yarns 171a and 171b and the second weft yarns 172a and 172b each have two repeating units. The section XII shows the weft-direction connected structure 92. In order to connect the first fabric 18 and the second fabric 28 in the weft direction at the ninth interval p9, the first weft 171b is the ninth. Are intersected with the third warp 163 and the fourth warp 164 constituting the second fabric 26 (see FIGS. 9C1 and 9C2).

  The high shrinkage yarn 38 has a high shrinkage rate compared to the fibers constituting the warp-direction double woven fabric. As the warp yarn on at least one side of the double woven fabric, which is the lining or front side, Used at 10 intervals p10. Here, the high shrinkage yarn 38 is used as the warp yarn, and even one warp yarn is integrated with the fabric structure, so even one high shrinkage yarn 38 is sufficient on the fabric structure, but the shrinkage is further increased. If you do, you may put more than one. The fibers constituting the warp-direction-shrinking air-woven fabric include the first warp 161, the second warp 162, the third warp 163, the fourth warp 164, the first wefts 171a and 171b, and the second Weft yarns 172a and 172b are included. The tenth interval p10 can be determined independently of the ninth interval p9. Typically, if the tenth interval p10 is substantially the same as the ninth interval p9, a blister with a plain weave ups and downs pattern is obtained.

  Next, a method for weaving such a double-woven fabric with a shrinkage in the warp direction will be described. FIG. 10 is a flowchart showing a method for producing a warp-direction double woven fabric. First, as the warp yarn, the high shrinkage yarn 38 is set at the tenth interval p10, and the fibers constituting the woven fabric are set (step S400). Next, the first fabric 18 is woven through the first weft yarns 171a and 171b while the first warp yarn 161 and the second warp yarn 162 are crossed (step S402). Further, the second fabric 28 is woven through the second weft yarns 172a and 172b while the third warp yarn 163 and the fourth warp yarn 164 are crossed (step S404).

  Next, it is determined whether the first wefts 171a and 171b and the second wefts 172a and 172b have advanced the ninth distance p9 in the weft direction (step S406). Then, the process proceeds to step S410. If Yes in step S406, the first fabric 18 and the second fabric 28 are intersected in the weft direction at the ninth interval p9 to form the weft-direction connected tissue 92 (step S408). Then, it is determined whether the width to be woven between the first fabric 18 and the second fabric 28 can be secured (step S410), and if No, the process returns to S402. If Yes in step S410, it is determined whether the width to be woven has been secured (step S412). If Yes, the process ends. If No in step S412, the first weft yarns 171a and 171b and the second weft yarns 172a and 172b are set as the next weft yarn (step S414), and the process returns to S402.

  FIG. 11 is a structural view showing a fabric structure of a double woven fabric of warp direction shrinkage (warp swelling) showing a fifth embodiment of the present invention, and shows a plain weave case. 11A is a plan view seen from the lining side, FIG. 11B is a cross-sectional view taken along the line BB in FIG. 11A, and FIG. 11C is taken along line C1-C1 in FIG. A warp direction sectional view of a normal fiber, (C2) is a weft direction sectional view of a high shrinkage yarn along C2-C2 of FIG. In the fifth embodiment, a plastic film yarn 180 is used at the eleventh interval p11 in place of the first warp yarn 161 and the second warp yarn 162 in the fourth embodiment. Therefore, here, in the description of FIG. 11, only the portions different from FIG. 9 will be described, and redundant description will be omitted.

  In the figure, fibers such as silk are used as the fibers constituting the double woven fabric with a shrinkage in the vertical direction. Then, a plastic film yarn 180 is used at the eleventh interval p11 in the same warp direction as the high shrinkage yarn 38 on the cloth 18 that forms the lining of the high shrinkage yarn 38. The plastic film yarn 180 is in the form of a thin tape having a width wider than the diameter of the fibers constituting the woven fabric, and is made of, for example, transparent or made of nylon colored in the same color as the fibers constituting the woven fabric. The width of the film yarn 180 may be appropriately determined, for example, in the range of 2 to 10 times the diameter of the fibers constituting the woven fabric, and the thickness may be selected to the same extent as the fibers constituting the woven fabric. Here, two plastic film yarns 180 are used in the tenth interval p10 which is a repeating unit of the high shrinkage yarn 38. Therefore, the two plastic film yarns 180 are used here by dividing the repeating unit p10 of the high shrinkage yarn 38 into two parts, p11a and p11b.

  In the double woven fabric constructed as described above, the plastic film yarn 180 prevents damage to the fibers constituting the woven fabric and increases the durability of the double woven fabric. Even when used for more than half a year, the state of the fabric structure having a relatively high porosity is maintained with a small amount of fibers of the double woven fabric. On the other hand, in the comparative example using only silk for the double woven fabric, when it was used for about half a year, the fiber structure of the silk thread was partially broken or cut, and the touch was deteriorated. The plastic film yarn 180 is considered to have a role of releasing static electricity generated in the fibers constituting the woven fabric, thereby preventing yarn pilling. Here, pilling refers to a phenomenon in which the surface of the fabric is rubbed and fluffed and entangled to produce small spherical pills. Accordingly, the plastic film yarn 180 may be made of polyester or other plastic film subjected to conductive processing in addition to the currently available nylon or Tetron (registered trademark).

  The use of the plastic film yarn 180 is not limited to the warp-direction-reduced double-woven fabric, but the weft-direction-reduced double-woven fabric, the air-flowing tissue fabric, and the warp-direction-reducing air-flowing tissue. It can also be applied to textiles. In this case, the plastic film yarn 180 is preferably used in the same direction as the weft direction in which the high shrinkage yarn is used. The eleventh interval can be selected as appropriate. For example, based on the repeating unit of the weft-direction ventilation structure of the ventilated fabric, the repeating unit of the weft-direction connected structure of the double-woven fabric, and the repeating unit of the high shrinkage yarn A repeating unit that is the same as or finer than the repeating unit may be used. Further, the plastic film yarn 180 may be used in a direction perpendicular to the weft direction in which the high shrinkage yarn is used. In this case, since the plastic film yarn 180 is in a direction in which swelling occurs due to the influence of the high shrinkage yarn, it is preferable to reduce the thickness and width of the plastic film yarn 180 to reduce the rigidity of the plastic film yarn 180. .

  Moreover, in the said embodiment, although demonstrated to the example of the ventilation structure | tissue fabric and double woven fabric of a double structure, this invention is not limited to this, The multiple structure | tissue of a triple or more may be sufficient. In this case, the presence of the double-structured air-permeable tissue fabric or double-woven fabric of the present invention between any two of the multi-structures makes it possible to form pleated wrinkles due to high-shrinkage yarns. It is light in weight, has good heat retention, and can be changed in design.
