[Figure 2-1] 1 is a woven fabric structure diagram 1 illustrating the proportion of open feathers in a basic structure 3. [Figure 2-2] 1 is a woven fabric structure diagram 2 illustrating the proportion of open feathers in a basic structure 3. [Figure 3] 1 is a woven fabric structure diagram illustrating the weave structure of basic structure 3. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the scope of the present invention is not limited to the illustrated examples. FIG. 1 is a diagram illustrating a schematic configuration of a woven fabric 1 according to this embodiment. As shown in FIG. 1, the woven fabric 1 is a cloth or fabric woven from a combination of warp and weft threads, such as a plain weave, twill weave, or satin weave. The woven fabric 1 has four sections: Section A, Section B, Section C, and Section D. Specifically, the woven fabric 1 includes Section A, Section B, Section C, and Section D, and has a basic weave 3, which is the smallest repeating unit, and is a cloth or fabric in which the basic weave 3 is repeated at a predetermined cycle. In this example, the woven fabric 1 is constructed by repeating the basic weave 3 at a predetermined cycle using the arrangement direction of the warp threads W, the arrangement direction of the weft threads F, or a combination of these. Furthermore, sections A, B, C, and D are woven using warp yarn W1, weft yarn F1 having a smaller fineness than weft yarn F2 (described later), and weft yarn F2 having a larger fineness than weft yarn F1. Section A is adjacent to sections B and C, and section D is adjacent to sections B and C.

[0015] Section A is an example of a first section according to the present invention, and is a section composed only of weft F1. Section A is a section in which the density of warp W1 arranged in the direction of warp W is sparse. Specifically, in section A, warp W1 is not arranged in the direction of warp W, and multiple wefts F1 are arranged in the direction of weft F. In other words, in section A, only multiple wefts F1 are arranged. In order to further improve the transparency of section A, it is preferable that the difference between the fineness of weft F1 and the fineness of warp W1 and weft F2 is large. In order to further reduce the transparency, it is preferable that the difference between the fineness of weft F1 and the fineness of warp W1 and weft F2 is small. Furthermore, in this example, section A has a thinner fabric thickness than sections other than section A (section B, section C, and section D).

[0016] Section B is an example of a second section according to the present invention, and is a section composed only of weft F2. Section B is a section in which the density of warp threads W1 arranged in the direction of the warp threads W is low. Specifically, in section B, warp threads W1 are not arranged in the direction of the warp threads W, and multiple weft threads F2 are arranged in the direction of the weft threads F. In other words, in section B, only multiple weft threads F2 are arranged.

[0017] Section C is an example of a third section according to the present invention, and is a section made up of warp threads W1 and weft threads F1. Section C is a section in which the density of warp threads W1 arranged in the direction of the warp threads W is high. Specifically, section C is woven with a plurality of warp threads W1 arranged in the direction of the warp threads W and a plurality of weft threads F1 arranged in the direction of the weft threads F.

[0018] Section D is an example of the fourth section according to the present invention, and is a section composed of warp threads W1 and weft threads F2. Section D is a section in which the density of warp threads W1 arranged in the direction of the warp threads W is high. Specifically, section D is woven with multiple warp threads W1 arranged in the direction of the warp threads W and multiple weft threads F2 arranged in the direction of the weft threads F.

[0019] The warp threads W1 are an example of warp threads according to the present invention, and are threads arranged in the warp direction when weaving on a loom. The warp threads W1 are multifilament threads with a higher fineness than the weft threads F1 described below, for example, with a larger diameter than the weft threads F1. Note that the warp threads W1 in this example are multifilament threads because of the risk of the threads irritating the skin due to physical effects, but monofilament threads may also be used. The thickness of the warp threads W1 is, for example, 30d (d: denier) or more and 1000d or less, specifically 30d or more and 500d or less, more specifically 30d or more and 300d or less, and the warp threads W1 in this example are 150d.

[0020] The weft F1 is an example of the first weft according to the present invention, and is a thread arranged in the weft direction when weaving on a loom. The weft F1 has a lower fineness than the warp W1 and weft F2, and is, for example, a multifilament thread that is thinner than the warp W1 and weft F2. Note that the weft F1 in this example is a multifilament thread because there is a risk that the thread may irritate the skin due to physical action, but a monofilament thread may also be used. The thickness of the weft F1 is, for example, 5d (d: denier) or more and 75d or less, specifically 10d or more and 60d or less, more specifically 20d or more and 40d or less, and the thickness of the weft F1 in this example is 30d. The thickness of the weft F1 in this example is 1 / 5 of the thickness of the weft F2 or the warp W1.

[0021] The weft yarn F2 is an example of a second weft yarn according to the present invention, and is a yarn arranged in the weft direction when weaving on a loom. The weft yarn F2 is a multifilament yarn having a finer thread than the weft yarn F1, for example, a thicker thread than the weft yarn F1. Note that the weft yarn F2 in this example is a multifilament yarn because there is a risk that the yarn may irritate the skin due to physical action, but a monofilament yarn may also be used. The thickness of the weft F2 is, for example, 30d (d: denier) or more and 1000d or less, specifically 30d or more and 500d or less, more specifically 30d or more and 300d or less, and the weft F2 in this example is 150d.

[0022] The fibers constituting the warp yarn W1, weft yarn F1, or weft yarn F2 may be synthetic fibers, natural fibers, or conjugate yarns (composite fibers) made by combining synthetic fibers and natural fibers. For example, when the fibers constituting the warp yarn W1, weft yarn F1, or weft yarn F2 are synthetic fibers, they may be polyester fibers such as polyethylene terephthalate, polybutylene terephthalate, or polytrimethylene terephthalate, polyamides such as nylon 6 or nylon 66, polyacrylic, polypropylene, or polyurethane, or may be conjugate yarns made by combining these synthetic fibers. Furthermore, when the fibers constituting the warp threads W1, weft threads F1, or weft threads F2 are semi-synthetic fibers, they are acetate, rayon, etc. When the fibers constituting the warp threads W1, weft threads F1, or weft threads F2 are natural fibers, they are wool, silk, cotton, hemp, etc., and may also be conjugate yarns made by combining these natural fibers. In the woven fabric 1 of this example, from the viewpoint of achieving a stretchable fabric with a textured surface, a combination may be adopted in which one of the warp yarns W and the weft yarn F contains a polyester fiber yarn such as polybutylene terephthalate or polytrimethylene terephthalate, and the other contains a polyurethane yarn. Specifically, when the warp yarn W1 contains a plurality of polyester fiber yarns, at least one of the weft yarns F1 and F2 may contain a plurality of polyurethane yarns. Alternatively, when the warp yarn W1 contains a plurality of polyurethane yarns, at least one of the weft yarns F1 and F2 may contain a plurality of polyester fiber yarns. Furthermore, the warp yarn W1, the weft yarn F1, and the weft yarn F2 may each contain a plurality of polyester fiber yarns and a plurality of polyurethane yarns, respectively.

[0023] FIG. 2-1 is a fabric structure diagram 1 illustrating the proportion of open feathers in the basic structure 3. Figure 2-2 is a fabric structure diagram 2 that explains the proportion of open feathers in the basic structure 3. As illustrated in Figures 2-1 and 2-2, the basic structure 3 is an example of a basic structure according to the present invention, and is a basic unit of repetition in the weave structure of the woven fabric 1, and is a structure having a minimum repeating unit including a section A, a section B, a section C, and a section D. In the basic structure 3 of this example, the minimum repeating unit is a section A, a section B, a section C, and a section D. The basic structure 3 may also be referred to as, for example, one repeat or one cycle. The basic structure 3 is periodically and repeatedly developed in the arrangement direction of the warp yarns W and the arrangement direction of the weft yarns F. The sections A and B in which the warp threads W1 are not arranged occupy a proportion of 1 / 2 or less of the total number of arranged warp threads in the direction of arrangement of the warp threads in the basic structure 3. Specifically, the sections A and B occupy a proportion of 1 / 40 or more and 1 / 2 or less of the total number of arranged warp threads in the direction of arrangement of the warp threads, more specifically, a proportion of 1 / 20 or more and 1 / 2 or less, and even more specifically, a proportion of 1 / 6 or more and 1 / 2 or less. The basic structure 3 can have, for example, 100 or less warp arrangement frames for arranging warp threads, specifically, 18 to 80. The number of arrangement frames for arranging warp threads and weft threads and the number of threads in one set can be changed as appropriate depending on the weave of the basic structure 3.

[0024] As shown in Figure 2-1(A), the basic structure 3 has 18 warp arrangement frames for arranging warps, and three warps are repeatedly arranged in sets for the warp arrangement frames that arrange 18 warps. In the basic structure 3, warp threads W1 are arranged in a ratio of 15:0 in the warp arrangement direction. Therefore, section A and section B account for 1 / 6 of the total number of warps arranged in the warp arrangement direction in the basic structure 3. As shown in Fig. 2-1(B), the basic structure 3 has 80 warp arrangement frames for arranging warp threads, and two warp threads are repeatedly arranged in pairs in the warp arrangement frames for arranging 80 warp threads. In the basic structure 3, warp threads W1 are arranged in a ratio of 78:0 in the warp arrangement direction. Therefore, section A and section B account for 1 / 40 of the total number of warp threads arranged in the warp arrangement direction in the basic structure 3.

[0025] As shown in Figure 2-2(C), the basic structure 3 has 18 warp arrangement frames for arranging warps, and three warps are repeatedly arranged in groups in the warp arrangement frames for arranging 18 warps. In the basic structure 3, the warp W1 is repeatedly arranged twice in a ratio of 6:0 in the warp arrangement direction. The warp W1 is repeatedly arranged twice at equal intervals. Therefore, the sections A and B are repeatedly arranged twice at equal intervals in the warp arrangement direction. The sections A and B account for 1 / 3 of the total number of warps arranged in the warp arrangement direction in the basic structure 3. As shown in FIG. 2-2(D), the base structure 3 has 18 warp arrangement frames for arranging warps, and three warps are repeatedly arranged in groups in the warp arrangement frames for arranging 18 warps. In the base structure 3, the warp W1 is repeatedly arranged three times in a ratio of 3:0 in the arrangement direction of the warp W. Therefore, sections A and B are repeatedly arranged three times at equal intervals in the arrangement direction of the warp. Sections A and B account for half of the total number of warps arranged in the arrangement direction of the warp in the base structure 3.

[0026] In this way, in the basic structure 3, sections A and B in which warp F1 is not arranged occupy a proportion of 1 / 40 to 1 / 2 of the total number of warps that can be arranged in the arrangement direction of the warps in the basic structure 3. Note that if sections A and B are formed in the basic structure 3 at a proportion exceeding 1 / 2 of the total number of warps that can be arranged, the number of arranged warps will decrease, which may result in yarn misalignment. Also, if sections A and B are formed in the basic structure 3 at a proportion less than 1 / 40 of the total number of warps that can be arranged, the area of ​​open feathers will become smaller, which may result in a loss of breathability. Therefore, it is preferable to form sections A and B in the basic structure 3 at a proportion of 1 / 40 to 1 / 2 of the total number of warps that can be arranged.

[0027] FIG. 3 is a weave diagram illustrating the weave of the basic structure 3. As shown in FIG. 3, the basic structure 3 has a structure in which, for example, a set of three warp threads is repeatedly arranged in a warp arrangement frame for arranging 18 warp threads, and a set of one to three weft threads is repeatedly arranged in a weft arrangement frame for arranging 14 weft threads. In the basic structure 3, warp yarn W1 is arranged twice in a ratio of 6:0 in the direction of warp arrangement. Therefore, sections A and B are arranged twice in a ratio of 2:5 in the direction of warp arrangement. In addition, in the basic structure 3, weft yarn F1 and weft yarn F2 are arranged twice in a ratio of 2:5 in the direction of weft arrangement. Note that weft yarn F2 includes weft yarn F2B and weft yarn F2C, and weft yarn F2B and weft yarn F2C are arranged alternately. Therefore, sections A and B are arranged twice in a ratio of 2:5 in the direction of weft arrangement.

[0028] In the weft yarn F2, the weft yarn F2B or the weft yarn F2C is a functional yarn, and in this example, the weft yarn F2B and the weft yarn F2C are functional yarns. Note that this is not limited to the weft yarn F2, and for example, the warp yarn W1 may be configured to include the warp yarn W1A and the warp yarn W1Z, and the warp yarn W1A or the warp yarn W1Z may be a functional yarn. The weft yarns F2B and F2C are, for example, stretchable elastic yarns such as polyurethane, decorative yarns (decorative twisted yarns) that improve design, such as knotted yarns, spiral yarns, mottled yarns, loop yarns, slub yarns and curled yarns, yarns with moisture-absorbing and quick-drying properties, yarns with a cool-to-the-touch property, or yarns with UV protection properties. The weft yarn F2B in this example is an example of the first yarn according to the present invention, and is, for example, a fancy yarn (fancy twisted yarn) that improves the design. The weft yarn F2B is arranged adjacent to the weft yarn F2C and has a different functionality from the weft yarn F2C. The weft yarn F2B is, for example, 30 d or more and 300 d or less, and in this example, is 150 d. The weft yarn F2C in this example is an example of the second yarn according to the present invention and is an elastic yarn with stretchability. The weft yarn F2C is, for example, 84T / 2 strands. The weft yarn F2C is arranged adjacent to the weft yarn F2B and has different functionality from the weft yarn F2B.

[0029] The woven fabric 1 is a mesh-like fabric formed by repeating a basic weave 3 including sections A, B, C, and D. Examples of woven products that at least partially include this woven fabric 1 include office wear, work clothes, nurse's uniforms, caregiver's uniforms, school uniforms, sportswear, underwear, coats, blousons, blouses, shirts, skirts, and slacks. The woven fabric 1 is required to have breathability and coolness, as well as thickness, density, and a well-balanced texture with well-balanced warp and weft threads. Examples of uses for the woven fabric 1 include interior items such as curtains. However, this is not a limitation, and the entire woven product may be made of the woven fabric 1.

[0030] In addition, the fabric 1 has a breathability (cm ) measured by JIS L-1096:2010 Method A (Fragile method). 3 / cm 2 ·sec) is, for example, 30cm 3 / cm 2 sec or more, specifically, 30 cm 3 / cm 2 ·sec or more 250cm 3 / cm 2 sec or less, more specifically, 40 cm 3 / cm 2 ·sec or more 200cm 3 / cm 2 ·sec or less, and more specifically, 40c cm 3 / cm 2 ·sec or more 100cm 3 / cm 2 ·sec or less.

[0031] As described above, according to the woven fabric 1 of this embodiment, a mesh-like fabric with a unique texture and regular unevenness can be obtained by repeating the basic weave 3 including sections A to D at a predetermined cycle. Furthermore, the woven fabric 1 can maintain an appropriate transparency and also create breathability due to sections A and B where the warp threads W1 are not aligned. Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications and additions can be made without departing from the spirit of the invention.
