Description

  The present invention relates to a woven fabric having a soft and light texture suitable for various towel products and skin futons.

  As a woven fabric used for a towel or the like, a pile woven fabric in which a pile yarn is arranged in a ground structure is generally used. Examples of the pile woven fabric include those obtained by cutting the pile yarn into a fluff shape, and those obtained by leaving the pile yarn in a loop shape. Such pile fabrics have a soft feeling and good heat retention, and are used for various purposes in addition to summer hangings such as towels.

  In addition to the above-mentioned pile fabrics, double fabrics and triple fabrics are known as soft fabrics (see, for example, Patent Document 1).

In addition, as a fabric product with a soft feeling, quilting is also known in which a cotton is inserted between a front cloth and a back cloth and stitched.

  However, the pile woven fabric and the double / triple woven fabric are limited in thickness. In other words, if the yarn is thickened to increase the thickness, the fabric itself becomes heavy and the feeling of use is impaired.

  On the other hand, the quilting can be made relatively thick and has the advantage that it is bulky and has a softer feeling than a pile fabric or the like. However, in the manufacturing process, it is necessary to first weave the front cloth and the back cloth and then quilt them with a cotton sandwich therebetween, which causes a problem that the process is complicated and the manufacturing cost is high.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a woven fabric that can keep the manufacturing cost low and has a soft and light texture.

  The layered fabric according to the present invention is a layered fabric of a triple structure, wherein a bulky yarn of a filament is used for at least a part of the weft constituting the middle layer of the triple structure. To do.

  Since the bulky yarn of the filament is soft and bulky, by using this for the middle layer as described above, the entire laminated fabric becomes a light and fluffy and relatively thick fabric, and has excellent heat retention. It will be a thing.

  In addition, a bulky yarn made of staples (short fibers) tends to cause the fibers to fall off, and the bulkiness tends to deteriorate with continued use. However, a bulky yarn made of filaments (long fibers) as in the present invention may be used. Therefore, the fiber does not easily fall off, and the bulkiness can be maintained.

As described above, according to the present invention, a soft fabric as described above can be obtained simply by weaving a triple woven fabric, and a process such as a quilting process is not required, thus simplifying the manufacturing process and keeping costs low. be able to.

  Examples of the bulky yarn include bulky yarn and textured yarn, and more specifically, false twisted yarn by false twisting of polyester filament yarn. As the thickness of the bulky yarn, 300-2100 dtex is recommended.

  In the layered fabric of the present invention, it is preferable to use polyurethane elastic yarn as a part of the weft in the middle layer.

  When the polyurethane elastic yarn (commonly referred to as spandex yarn) shrinks, the upper and lower layers of the triple woven fabric also shrink and become wrinkles, so that the entire woven fabric has a volume and a softer texture.

  The layered fabric according to the present invention has a soft and light texture while being a relatively thick fabric, and can reduce the manufacturing cost.

It is the figure which represented typically the partial cross section of the laminated fabric which concerns on Embodiment 1 of this invention. It is the figure which represented typically the partial cross section of the laminated fabric which concerns on Embodiment 2 of this invention.

<Embodiment 1>
FIG. 1 is a diagram schematically showing a partial cross section of a layered fabric 10 according to Embodiment 1 of the present invention.

  The laminated fabric 10 is a fabric having a three-layer structure including an upper layer, a middle layer, and a lower layer. The upper weft 11 and warp yarn 12 and the lower weft 17 and warp yarn 18 are all 20th spun yarn of 100% cotton. The upper and lower layers have a plain weave structure, and the upper and lower weft yarns 11 and 17 cross the middle layer warp yarns 16 at some points. In the illustrated example, the warps 12 and 18 intersect with the middle-layer warp 16 at a pitch of every six.

  In the middle layer, one of the wefts 14 floats to the warp 16 and sinks five, the weft 15 floats to the warp 16 and one sinks, and the weft 19 is one to the warp 16 one by one. Repeat sinking and floating alternately. In the middle layer, the weave structure of these three wefts 14, 15, 19 and warp 16 is repeated.

  Bulky yarns are used for the weft yarns 14 and 15 of the middle layer weft yarns. These bulky yarns (weft yarns 14 and 15) are false twisted yarns of polyester filament yarn, and have a thickness of 333 dtex (300d). Bulky yarns (wefts 14, 15) may be sweet-twisted. When the bulky yarn is a twisted yarn, if the twist is too strong, the bulkiness is impaired. Therefore, the number of twists is preferably 200 / m or less.

  Of the middle-layered wefts, the 20th spun yarn of 100% cotton is used for the weft 19 and the warp 16.

  As described above, the woven fabric 10 uses bulky yarns for the middle layer, so that a woven fabric having a bulge can be obtained simply by weaving with a triple weaving machine without quilting.

  During weaving, the crimps may be extended by applying tension to the bulky yarns as the weft yarns 14 and 15, but the desizing process after weaving (into a dryer at 140 ° C in 80-90 ° C hot water) The bulky yarns (wefts 14, 15) are crimped back by heating during the drying step), and a bulky feeling is obtained. Also, at this time, the upper, middle and lower layers are woven once the bulky yarns are stretched, so that the bulky yarns shrink in the subsequent desizing process, etc. The bulky fabric 10 as a whole has a good bulkiness. In addition, since the weave structure of the middle layer is a structure in which the bulky yarn (wefts 14, 15) skips five warps 16 and crosses one, as described above, the crimping of the bulky yarn has one crossing It seems to be fastened at the point, and it shrinks at the part where five are skipped. As a result, almost uniform crimps appear in the upper and lower layers.

  If the bulky yarn is simply inserted in the weft direction without crossing the warp yarn (no fastening portion), the upper and lower layer wrinkles become rough and the aesthetics of the appearance of the laminated fabric are inferior. As described above, in the first embodiment, crimping is performed, so that not only the bulkiness and heat retention are good, but also a good appearance is exhibited. In order to make such a crimp, the number of warp 16 skipped by the bulky yarns (wefts 14 and 15) in the middle layer is preferably 3 to 20.

  As described above, the layered fabric 10 of Embodiment 1 is bulky, and thus has a soft and light texture.

<Embodiment 2>
FIG. 2 is a diagram schematically showing a partial cross-section of the layered fabric 20 according to the second embodiment of the present invention.

  In the second embodiment, instead of the weft yarn 19 of the cotton spun yarn in the middle layer of the first embodiment, a 40-number double yarn spandex yarn (polyurethane elastic yarn: spandex yarn 29) is used. The spandex yarn 29 is woven with a structure in which five of the spandex yarns 29 are floated with respect to the warp 16 and one of them is sunk. Other configurations in the second embodiment are the same as those in the first embodiment.

  In the layered fabric 20 of the second embodiment, the spandex yarn 29 causes the middle layer and the upper and lower layers to further shrink and become wrinkles, and the bulkiness is very good. This also provides excellent heat retention.

  The layered fabric 20 is also bulky, has a soft and light texture, and the manufacturing process is simplified as compared with the case of quilting, so that the manufacturing cost can be reduced.

  The present invention has been described more specifically with examples. However, the present invention is not limited by the above examples, and may be implemented with appropriate modifications within a range that can meet the above-mentioned purpose. Of course, they are all possible and are included in the technical scope of the present invention.

  For example, the number of warp yarns 16 of bulky yarns (weft yarns 14 and 15) is not limited to five as in the first and second embodiments, and may be six, eight, or twelve, for example.

  In the first and second embodiments, the bulky yarn is used for only a part of the weft used for the middle layer, but all the middle layer wefts may be composed of the bulky yarn of the filament.

  Various functional yarns such as cold feeling, heat generation and antibacterial may be used for the warp and weft used for the middle layer. In this case, since the middle layer is hidden by the upper and lower layers and does not directly touch the skin, even if the above-mentioned functional yarn itself feels poor, it hardly affects.

  In the first and second embodiments, 100% cotton spun yarn is shown as the upper and lower yarns. However, the yarn is not limited to this, and yarns of various materials such as hemp, wool, and synthetic fibers can be used.
