Woven fabric and obi using the same

Abstract

To provide a woven fabric which allows wrinkles of soft feeling to be freely formed, and to provide an Obi using the same.SOLUTION: A woven fabric is obtained by weaving warp and weft, and has a hollow weave part 10 extending in the warp direction and a joining part 20 extending in the warp direction. The hollow weave part 10 has an upper cloth 110 and a lower cloth 120, and has a stretchable weft 11 and a non-stretchable weft 12 which connect a pair of joining parts 20 putting the hollow weave part 10 therebetween and are disposed inside the hollow weave part. The stretchable weft 11 contracts the hollow weave part 10 in the lateral direction, the upper cloth 110 and the lower cloth 120 are bent so as to protrude outward, and the non-stretchable weft 12 controls the degree of bending of the upper cloth 110 and the lower cloth 120. Thus, wrinkles are formed by the hollow weave part 10.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a woven fabric and an obi (sash), particularly a heko obi (belt), using the same. [Background technology]

[0002] Heko-obi is an obi made of a thin and soft material, and has the characteristic that it is easy to tie without putting strain on the body when fastened, and it is widely used because it has a high degree of freedom in arrangement, such as being able to be tied in any way. Among them, wrinkled heko-obi, which has wrinkles all over, is known because it can be presented cutely. The wrinkles in this wrinkled heko obi are generally produced by forming wrinkles in an obi made of a soft material, and then subjecting it to a wrinkling process, such as steaming it to make it retain its shape.

[0003] The applicant has been developing an obi that does not undergo a wrinkle treatment and that has natural wrinkles formed by weaving the threads in the weaving process. As shown in Figure 4, the applicant has completed and is selling a heko obi, which is a woven fabric F having a hollow weave portion B (a double woven portion woven in a hollow shape) that extends in the warp direction, and in which an elastic thread is provided independently within the hollow weave portion B to connect a pair of weaving portions that sandwich the hollow weave portion B. This product is made by shrinking the hollow weave portion in the short direction (weft direction) to bend the upper and lower fabrics of the hollow weave portion so that they curve or protrude outward, forming wrinkles in the warp direction on the front and back of the fabric.

[0004] On the other hand, as a technique related to heko obi, for example, Patent Document 1 discloses a heko obi consisting of a rear belt as a knotted part, a front belt as a part wrapped around the waist, and a small belt for connecting the front belt and the rear belt. The wrinkles in the rear belt of this heko obi are formed from the center to the ends by squeezing a rectangular piece of cloth in the center. The wrinkles in the front belt and the small belt are also formed so as to extend in the short direction of the tubular belt by shrinking the tubular belt with an elastic core inside in the longitudinal direction. However, this heko obi requires processing or treatment after weaving the fabric.

[0005] Although not intended for use as a heko obi, double-layered fabrics are known in which linear protrusions or wrinkles are formed on the surface by weaving the threads during the weaving process. For example, Patent Document 2 discloses a double-layered fabric with vertically extending convex ridges formed on the surface. In this double-layered fabric, the shrinkage rate of the weft yarn of the front fabric is made smaller than that of the back fabric, and vertically extending convex ridges are formed on the front side, which shrinks less. In Patent Document 2, post-treatment is performed to shrink the weft yarn. Furthermore, Patent Document 3 discloses a narrow woven fabric for belts, which is made of an outer tubular sheet cloth extending in the longitudinal direction and flat-woven with warp and weft yarns, and in which a non-elastic core thread and an elastic core thread are inserted along the longitudinal direction inside the outer tubular sheet cloth. The wrinkles in this narrow woven fabric are formed so as to extend in the lateral direction of the narrow woven fabric by shrinking the narrow woven fabric in the longitudinal direction using the elastic core thread inside the outer tubular sheet cloth. Patent Document 4 also discloses a similar technology. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 53-73120 [Patent Document 2] JP 2004-84129 A [Patent Document 3] JP 2011-117091 A [Patent Document 4] JP 2018-66094 A Summary of the Invention [Problem to be solved by the invention]

[0007] The applicant's product is one in which the hollow weave portion is shrunk in the short direction, and wrinkles are formed in the long direction. However, if the hollow weave portion is shrunk too much, the upper and lower fabrics of the hollow weave portion will be folded more strongly, the wrinkles will be too prominent, and the texture will become hard. Conversely, if the hollow weave portion is not shrunk sufficiently, the convexities will be small, and the wrinkles will not be visible. Therefore, it is difficult to fine-tune the wrinkles, and a woven fabric with a high degree of wrinkle freedom is required.

[0008] When using the conventional double-layered fabric technology, the double-layered fabric of Patent Document 2 is shrunk in the horizontal direction to form the convex ridges, which reduces the overall softness. In particular, it is not possible to form the soft wrinkles of a heko-obi. Furthermore, the convex ridges are formed by making the shrinkage rate of the weft yarn of the front fabric smaller than that of the back fabric, so the convex ridges are only formed in the front fabric. The woven fabrics of Patent Documents 3 and 4 have short wrinkles extending in the short direction formed by stretching a hollow weave portion extending in one direction in the longitudinal direction. Therefore, the length, direction, and texture of the wrinkles cannot be freely adjusted. Patent Documents 3 and 4 also do not aim to adjust the wrinkles. An object of the present invention is to provide a woven fabric that can be freely formed with wrinkles as a pattern while maintaining a soft feel, and a sash using the same. [Means for solving the problem]

[0009] In order to solve the problems with the applicant's products, the inventor used a relatively highly elastic stretchable yarn so that the formation of wrinkles would be more noticeable, and at the same time, a non-shrinkable yarn was also independently placed within the hollow woven portion to reduce the degree of folding of the upper and lower fabrics of the hollow woven portion.He discovered that this allowed the wrinkles to be formed firmly, but not stand up, resulting in a softer overall texture.

[0010] The woven fabric of the present invention is characterized in that it has a hollow weave portion woven from warp and weft threads and extending in either the warp direction or the weft direction, and that elastic and non-elastic threads are provided independently within the hollow weave portion to connect a pair of weaving portions that sandwich the hollow weave portion. Here, "the elastic and non-elastic threads are independent" refers to a state in which the elastic and non-elastic threads are not entangled with the upper and lower fabrics of the hollow weave portion, that is, they are not entangled or weaved with any of the warps or wefts that make up the upper and lower fabrics, and are not entangled with the elastic and non-elastic threads.

[0011] In the woven fabric of the present invention, an elastic thread is independently provided in the hollow woven portion to connect a pair of weaving portions that constitute the hollow woven portion, that is, an elastic thread is independently provided in a direction perpendicular to the longitudinal direction of the hollow woven portion. Therefore, the hollow woven portion is shrunk in its short direction, and the upper and lower fabrics of the hollow woven portion are bent so as to bend or protrude outward, and wrinkles extending in the longitudinal direction of the hollow woven portion are formed on both the front and back sides. In addition, a non-elastic thread is independently provided in parallel with the elastic thread, so that the degree of folding of the upper and lower fabrics can be controlled to create wrinkles with a soft texture. Furthermore, since the hollow weave portion can be freely formed within the fabric, wrinkles of any shape and position with a soft feel can be formed.

[0012] In the woven fabric of the present invention, the ratio of the number of the elastic yarns to the number of the non-elastic yarns is preferably 1:1 to 1:5. In the woven fabric of the present invention, the ratio of the number of the elastic yarns to the number of the warp yarns or the weft yarns of the upper and lower fabrics of the hollow woven portion extending in the same direction as the elastic yarns is preferably 1:5 to 1:20. When the ratio of the elastic yarns is reduced to within the above range, the elastic force of the hollow woven portion in the short direction can be reduced.

[0013] In the woven fabric of the present invention, it is preferable that the co-woven portion has a predetermined width. In this case, the co-woven portion becomes an area where wrinkles are not formed. This improves the design of the woven fabric.

[0014] The belt of the present invention is characterized by comprising the woven fabric of the present invention. The obi of the present invention can be designed with soft wrinkles at any position. It is particularly suitable for heko obi. Effect of the Invention

[0015] The woven fabric of the present invention can form wrinkles of any shape and at any position while having a soft feel, and can provide a woven fabric that is particularly suitable for use as a heko-obi (belt). [Brief description of the drawings]

[Figure 4] FIG. 1 is a schematic diagram showing a hollow weave portion and a co-woven portion of a conventional woven fabric cut in the vertical weft direction. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Next, the present invention will be described based on embodiments, however, the present invention is not limited to these embodiments.

[0018] "Textile 1" FIG. 1 shows an embodiment of a woven fabric of the present invention. The woven fabric 1 in FIG. 1 is woven with warp and weft threads, and has multiple hollow weave portions 10 extending in the warp direction and multiple co-woven portions 20 extending in the warp direction (the vertical direction in FIG. 1). The co-woven portions 20 are arranged to sandwich the hollow weave portions 10. The hollow weave portions 10 form the wrinkles in the woven fabric 1. The hollow weave portions 10 are arranged randomly within the woven fabric 1 to create natural wrinkles. In FIG. 1, the vertical direction is the warp direction, and the horizontal direction is the weft direction.

[0019] "Bukuro Oribe 10" 2a and 2b, the hollow woven part 10 has an upper cloth 110 woven with a front warp yarn 111 and a front weft yarn 112, and a lower cloth 120 woven with a back warp yarn 121 and a back weft yarn 122. The upper cloth 110 and the lower cloth 120 of the hollow woven part 10 are bonded together along a pair of bonding parts 20 that sandwich the hollow woven part 10. The hollow woven part 10 also has an elastic weft yarn 11 and a non-elastic weft yarn 12 inside that are independent of the upper cloth 110 and the lower cloth 120. FIG. 3a shows a structure unit of the hollow weave portion 10 used in the woven fabric 1, and FIG. 3c shows the structure diagram of FIGS. 2a and 2b using this structure unit. The hollow weave portions 10 formed in the woven fabric 1 are not limited to the structure shown in Figs. 2a and 2b, but may be in various shapes.

[0020] The elastic weft 11 and the non-elastic weft 12 connect a pair of weaving parts 20 that sandwich the hollow weave part 10, and are independent of each other. In other words, the elastic weft 11 and the non-elastic weft 12 are arranged substantially parallel to each other (parallel to the front and back direction of the paper surface of FIG. 2b), and are arranged independently without being entangled with the upper cloth 110 and the lower cloth 120 as shown in FIGS. 2a and 2b. In more detail, they are not entangled or connected to any of the warp threads or weft threads that constitute the upper cloth and the lower cloth. Therefore, the elastic weft 11 and the non-elastic weft 12 are entangled with the warp threads of both the weaving parts 20, and extend in the hollow weave part 10 so as to bridge from one weaving part 20 to the other weaving part 20. In this way, the elastic weft thread 11 and the inelastic weft thread 12 can be easily provided as weft threads of the fabric 1 on a loom.

[0021] The ratio of the number of elastic wefts 11 to the number of non-elastic wefts 12 in the hollow woven portion 10 is 1:1 to 1:10, preferably 1:2 to 1:5. For example, in the hollow woven portion 10 of Fig. 2a, the ratio is 1:2, as shown in Fig. 3c. The ratio of the total number of elastic wefts 11 and inelastic wefts 12 arranged to span the hollow woven portion 10 to the number of parallel wefts in the hollow woven portion 10 (total number of front wefts and back wefts) is 1:1 to 1:20, preferably 1:2 to 1:10, and particularly 1:3 to 1:5. For example, in the hollow woven portion 10 of Fig. 2a, the ratio is 1:4 as shown in Fig. 3c.

[0022] The elastic weft yarn 11 is not particularly limited as long as it has elasticity, but examples thereof include an elongation of 15 or more, preferably 18 or more, particularly 20 or more, and 40 or less. If the elongation is too low, it becomes difficult to form deep wrinkles. However, even if the elongation is less than 15, it is expected that the upper cloth 110 and the lower cloth 120 of the hollow woven part 10 will bend sufficiently and sufficient wrinkles will be formed if the flexibility of the warp and weft yarns and the non-elastic weft yarns constituting the hollow woven part 10 is sufficiently reduced (for example, the fineness is sufficiently reduced). The elongation is measured in accordance with JIS L1095 (2010). The elastic weft yarn is not particularly limited as long as it has elasticity, but examples thereof include urethane resin fibers (e.g., spandex) and processed yarns using the same, and in particular, covered yarns in which a polyurethane resin fiber is used as a core and another fiber (e.g., polyethylene or polyamide) is wrapped around the core are preferred.

[0023] The non-elastic weft yarn 12 may be any yarn having a lower elongation than the elastic weft yarn, and is preferably made of polyolefin, polyamide or polyester, particularly polyester. The warp threads (front warp threads and back warp threads) and weft threads (front weft threads and back weft threads) constituting the upper cloth 110 and the lower cloth 120 of the hollow woven portion 10 may be threads with elongation at least lower than that of the elastic threads. In particular, it is preferable to use the same threads as the inelastic weft threads.

[0024] The width of the hollow woven portion 10 is not particularly limited, but for example, the number of warp threads (front warp threads and back warp threads) is 4 or more, preferably 10 or more, and particularly preferably 20 or more and 50 or less. If the width of the hollow woven portion 10 is small, the upper cloth 110 and the lower cloth 120 are not folded well, and wrinkles are less likely to form. On the other hand, if the width of the hollow woven portion 10 is too large, wrinkles are less visible. The length of the hollow woven portion 10 is not particularly limited as long as it is long enough to be visible as wrinkles.

[0025] The co-woven portion 20 is constructed by plain weaving warp yarns 21 (front warp yarns and back warp yarns) and weft yarns 22 (front weft yarns, back weft yarns, stretchable weft yarns and non-stretchable weft yarns). Fig. 3b shows the structure unit of the co-woven part 20 of the woven fabric 1. A plain weave with one warp and two wefts is used in this woven fabric 1. By weaving in this way, the front weft 112 appears on the front side and the back weft 212 appears on the back side, making the front and back sides of the co-woven part 20 reversible.

[0026] The woven fabric 1 constructed in this manner has wrinkles formed by the hollow weave portion 10, as shown in Fig. 1 or Fig. 2a. More specifically, the hollow weave portion 10 shrinks in the weft direction as the elastic weft yarn 11 shrinks, causing the upper fabric 110 and the lower fabric 120 to bend or protrude outward, forming convex stripes extending in the warp direction on the front and back surfaces of the woven fabric 1. At this time, the non-elastic weft yarn 12 in the hollow weave portion 10 opposes the shrinkage of the hollow weave portion 10, giving the wrinkles formed a rounded appearance and a soft texture. This achieves natural wrinkles.

[0027] Although the woven fabric of the present invention has been described above, the present invention is not limited to the above description. For example, in the woven fabric 1 of FIG. 1, the hollow woven portion 10 extends in the warp direction, but it may extend in the weft direction. In addition, in the fabric 1 of FIG. 1, the co-woven portion 20 is a plain weave variegated weave, but as long as an integrated woven fabric can be constructed as the co-woven portion 20, the weaving method is not particularly limited, and other plain weaves, twill weaves, satin weaves, etc. may also be used. The upper cloth 110 and the lower cloth 120 of the hollow woven portion 10 are also plain woven, but other weaving methods may be used as long as the upper cloth 110 and the lower cloth 120 are each configured to bend due to the contraction of the elastic weft yarn in the hollow woven portion 10.
