[Technical field]

[0001] The present invention relates to multi-layer fabrics and coated articles. [Background technology]

[0002] Conventionally, techniques for making fabric using polyester fibers and then producing and providing clothing from the fabric are known, such as those described in Patent Document 1 below. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2000-144550 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, since chemical fibers (polyester fibers) are used, people who, for example, experience or are likely to experience allergies when the fibers come into contact with the skin need to avoid wearing clothing made of chemical fibers. In other words, it was not possible to wear clothing etc. that had the functionality that could be achieved with synthetic fibers.

[0005] The present invention has been made in view of the above circumstances, and aims to provide a multi-layer fabric and a covering that can provide the functions that can be achieved with synthetic fibers while suppressing the occurrence of allergies, for example. [Means for solving the problem]

[0006] In order to achieve the above object, a multi-layer fabric according to one embodiment of the present invention comprises: A multi-layer fabric that contacts at least a part of a human being as a target part, A first layer contacting the target portion; a second layer disposed on an opposite side of the first layer from the target portion and not in contact with the target portion; Equipped with the first layer being made of a fabric woven from non-polyester fibers; The second layer is comprised of a fabric woven from one or more fibers including polyester.

[0007] In order to achieve the above object, a coated article according to one embodiment of the present invention comprises: A covering article for covering at least a part of a human being as a target part, the covering article being made using a multi-layer fabric that comes into contact with the target part, The multi-layer fabric comprises: A first layer contacting the target portion; a second layer disposed on an opposite side of the first layer from the target portion and not in contact with the target portion; Equipped with the first layer being made of a fabric woven from non-polyester fibers; The second layer is comprised of a fabric woven from one or more fibers including polyester. Effect of the Invention

[0008] According to the present invention, for example, it is possible to suppress the occurrence of allergies while allowing the functions that can be achieved by chemical fibers to be exhibited. [Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is a diagram showing an example of a multilayer fabric according to one embodiment of the present invention, in which (a) is an exploded perspective view showing the configuration of the multilayer fabric, and (b) is a diagram showing the ends of each layer of (a). [Diagram 2] FIG. 1 is a front view of sleepwear (jacket) showing an example of a covering article according to an embodiment of the present invention. [Diagram 3] FIG. 1 is a front view of sleepwear (pants) showing an example of a covering article according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] FIG. 1 is a diagram showing an example of a multilayer fabric according to one embodiment of the present invention, where (a) is an exploded perspective view showing the structure of the multilayer fabric, and (b) is a diagram showing the ends of each layer in (a).

[0011] The multi-layered fabric TN shown in Fig. 1 is made by overlapping a plurality of fabrics. The multi-layered fabric TN is also such that one surface or the other surface, or both surfaces, of the multi-layered fabric TN come into contact with at least a part of a human being as a target part HT. The target part HT may be, for example, at least a part of the upper body or lower body of a person.

[0012] The multilayered fabric TN is a woven fabric having a predetermined length and width, for example, a substantially rectangular or strip-shaped fabric in plan view. The multilayered fabric TN is cut to a required size and processed (sewn) into covering products (sleepwear CP1 and sleepwear CP2) described later. The multi-layered fabric TN is capable of, for example, suppressing the occurrence of allergies while providing the functions that can be achieved with chemical fibers. To make this clear, the following description will be given.

[0013] The multi-layered fabric TN of this embodiment is made of four layers of fabric, although the number of layers is not particularly limited. In such a multi-layered fabric TN, two of the four layers of fabric are different types of fabric from the remaining two.

[0014] Of the above four pieces of fabric, the first two are collectively referred to as the first layer 1, and the latter two are collectively referred to as the second layer 2. The first layer 1 is composed of the first layer 1A, which is the closest to the target part HT shown in Figure 1, and the fourth layer 1B, which is the furthest away. The second layer 2 is composed of a second second layer 2A that is second closest to the target part HT, and a third second layer 2B. That is, the multilayer fabric TN of this embodiment is constructed so that the second layer 2A and the second layer 2B are sandwiched between the first layer 1A and the first layer 1B. As can be seen from FIG. 1, the second layer 2A is disposed on the opposite side of the first layer 1A to the target portion HT.

[0015] In addition, the multi-layered fabric TN of this embodiment is not particularly limited in the weaving method, but each of the four fabrics is woven in a plain weave. Specifically, the first layer 1A, the first layer 1B, the second layer 2A, and the second layer 2B are woven in a generally gauze-like manner with the same number of threads per square meter.

[0016] The number of threads per inch is not particularly limited, but is 50 threads vertically and 38 threads horizontally (50 warp threads x 38 weft threads) per inch. Therefore, unlike fabrics woven at a high density, the weave is coarse.

[0017] In this embodiment, the thickness of the yarns constituting each of the first layer 1A, the first layer 1B, the second layer 2A, and the second layer 2B is approximately the same, and the thickness is set taking into consideration, for example, the softness, feel, texture, etc. of the multilayer fabric TN.

[0018] The threads (fibers) used in the first layer 1A and the first layer 1B are, for example, thin fibers of cotton and polyurethane (PU) twisted together to form a single thread. Since such yarns (fibers) are used as the warp and weft threads to be woven in a plain weave, the first layer 1A and the first layer 1B can also be called "cotton x PU gauze", respectively.

[0019] On the other hand, the yarns (fibers) used in the second layer 2A and the second layer 2B respectively have warp yarns made of cotton and weft yarns (fibers) made of polyester (PEs). In this embodiment, in order to provide a heat-retaining function of radiating far-infrared rays emitted from the target part HT through the first layer 1A and retaining heat, ceramics are kneaded into the weft yarn (fiber) of the polyester (PEs) (minerals may also be kneaded into the weft yarn to enhance the far-infrared radiation effect).

[0020] The weft yarn (fiber) of polyester (PEs) with ceramics kneaded therein is adjusted so that it is contained in a predetermined minimum standard amount (for example, 20%) in each of the second layer 2A and the second layer 2B (this is an example). Although ceramics and the like are kneaded into the fabric, it is also possible to attach ceramics and the like to natural fibers (considering repeated washing, kneading the ceramics into the fabric is preferable).

[0021] The second layer 2A and the second layer 2B are woven in a plain weave with cotton warp threads having the above-mentioned thread count and polyester (PEs) weft threads (fibers) with ceramics kneaded into them. Furthermore, since the second layer 2A and the second layer 2B have the same thread count as the first layer 1A and the first layer 1B, the structure is such that the polyester (PEs) weft threads (fibers) do not come into contact with the target part HT, or make it very difficult for them to come into contact with it, via the first layer 1A and the first layer 1B.

[0022] In addition, with regard to a structure in which the polyester (PEs) weft yarn (fiber) does not come into contact with the target part HT, it is preferable to perform end processing so that the respective ends of the first layer 1A and the first layer 1B are positioned outside the respective ends of the second layer 2A and the second layer 2B. The above-mentioned "edge" refers to the outer edge of the fabric, such as the positions indicated by the leading lines of the reference numerals 1A, 1B, 2A, and 2B in FIG.

[0023] The second layer 2A and the second layer 2B each have a warp thread of cotton and a weft thread of polyester (PEs) kneaded with ceramics, so that the flexibility is different in the vertical and horizontal directions, which contributes to shape stability (prevention of deformation) after processing (sewn) into, for example, the coated products CP1 and CP2 described below.

[0024] In this embodiment, the multi-layered fabric TN has a material composition of 76% cotton, 21% polyester, and 3% polyurethane (this is an example).

[0025] In the above-mentioned configuration and structure, although the multilayer fabric TN uses polyester fibers, the fabric that comes into contact with the skin is the first layer 1, which does not contain polyester fibers, and therefore it is possible to prevent the occurrence of allergies. Furthermore, since the multilayer fabric TN has the second layer 2 containing polyester fibers, it is possible to achieve functions that can be realized with polyester fibers.

[0026] Furthermore, since the first layer 1A, the first layer 1B, the second layer 2A, and the second layer 2B of the multilayer fabric TN are each woven in a generally gauze-like shape, the multilayer fabric TN can exhibit an appropriate ventilation function (breathability). In addition, since the second layer 2A and the second layer 2B of the multilayer fabric TN each contain polyester (PEs) fibers with ceramics kneaded into them, the multilayer fabric TN can exhibit heat retention in addition to the moderate breathability described above (even if woven in an approximately gauze-like shape, the fabric can exhibit heat retention). The multi-layered fabric TN is expected to have the effect of promoting blood circulation by radiating far-infrared rays.

[0027] FIG. 2 is a front view of sleepwear (jacket) showing an example of a covering article according to one embodiment of the present invention. FIG. 3 is a front view of sleepwear (pants) showing an example of a covering article according to one embodiment of the present invention.

[0028] In this embodiment, by processing (sewing) the multilayer fabric TN, it is possible to provide sleepwear CP1 which becomes a jacket as shown in FIG. 2, and sleepwear CP2 which becomes pants as shown in FIG.

[0029] In the sleepwear CP1 and the sleepwear CP2, the first layer 1A serves as the lining and the first layer 1B serves as the outer layer, so that there is no contact with polyester fibers even when the sleepwear is being worn or changed, thereby preventing the occurrence of allergies.

[0030] Furthermore, since the sleepwear CP1 and the sleepwear CP2 have the second layer 2A and the second layer 2B containing polyester fibers, they can exhibit functions that can be achieved by polyester fibers.

[0031] In addition, since the first layer 1A, the first layer 1B, the second layer 2A, and the second layer 2B that make up the multilayer fabric TN of the sleepwear CP1 and the sleepwear CP2 are each woven in a roughly gauze-like manner, they can exhibit moderate ventilation function (breathability) (they can prevent heat from building up during sleep).

[0032] In addition, since the sleepwear CP1 and the sleepwear CP2 have second layers 2A and 2B that contain polyester fibers with ceramics (or minerals) kneaded into them, they can exhibit heat retention in addition to the moderate ventilation function described above. That is, the far-infrared radiation is expected to promote blood circulation, which can improve the quality of sleep.

[0033] Although the present invention has been described above with reference to FIGS. 1 to 3, the present invention is not limited to the above-described embodiment. Furthermore, the effects described in this embodiment are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in this embodiment.

[0034] In this embodiment, the multilayer fabric TN includes four pieces of fabric (first layer 1A, first layer 1B, second layer 2A, and second layer 2B), but this is not limited to the above. That is, the multi-layered fabric TN may have a second layer 2 made up of three layers, and a first layer 1A and a first layer 1B each made up of two layers.

[0035] In addition, in this embodiment, the four pieces of fabric (first layer 1A, first layer 1B, second layer 2A, and second layer 2B) that make up the multilayer fabric TN are each woven in a plain weave, but this is not limited to the above. That is, the fabric may be twill, satin, etc. Also, the multi-layer fabric TN may have different weaves for each layer.

[0036] In addition, in this embodiment, the threads (fibers) constituting the first layer 1A and the first layer 1B are made by twisting together thin fibers of cotton and polyurethane (PU) into one thread, but this is not limited thereto. In other words, the threads may be made of only cotton (a natural material).

[0037] In addition, in the present embodiment, the sleepwear CP1 and the sleepwear CP2 are given as examples of covering articles that cover the target part HT of a person, but this is not intended to be limiting. In other words, the above configurations and structures can also be applied to loungewear, underwear, T-shirts, pants, sleepers (for babies), swaddling cloths, blankets, sheets, quilt covers, pillowcases, hats, shawls, scarves, towels, handkerchiefs, etc.

[0038] In addition, in this embodiment, the first layer 1A, the first layer 1B, the second layer 2A, and the second layer 2B have the same number of threads per layer, but this is not limited to the above.

[0039] In addition, in this embodiment, no mention is made of the thickness of the yarns (fibers) used in the first layer 1A, the first layer 1B, the second layer 2A, and the second layer 2B. However, for example, in order to achieve the above-mentioned minimum standard amount (e.g., 20%), the weft yarns (fibers) of polyester (PEs) kneaded with ceramics may be made thicker than the others. The multilayer fabric TN, sleepwear CP1, and sleepwear CP2 of this embodiment were subjected to a 24-hour occlusive patch test on subjects with sensitive skin, and the results showed that they were safe products. Furthermore, with regard to the heat retention (heat retention function) of the multilayer fabric TN, sleepwear CP1 and sleepwear CP2 of this embodiment, results have been obtained showing that the skin temperature of people wearing this product is significantly higher than that of the comparison product. In addition, with regard to the multilayer fabric TN, sleepwear CP1 and sleepwear CP2 of this embodiment, results were obtained showing that the blood flow of people wearing this product was significantly higher than that of the comparison product.
