Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention has good ventilation characteristics, and
The present invention relates to a new type of bedding that has never been seen before, and which has appropriate heat retention and is rich in fashionability.

For more details, please refer to towel blankets, sheets, and quilt fabrics.
The present invention relates to new bedding items that can be suitably and comfortably used mainly for summer use, such as side clothes, pajamas, nightgowns, nightgowns, yukatas, and pillowcases.

[Prior Art] Traditionally, when designing products for bedding such as towel blankets and pajamas, priority has often been given to fashionability such as color and design, or brand name; Regarding functionality, it has mainly been left to the primary characteristics of the fiber material itself (for example, water absorption when using cotton).

But 1. On the other hand, especially during the rainy season and summer in Japan, when it's hot and humid and you sweat profusely, it's just plain! Relying only on the functional characteristics of the Li fiber material or fiber fabric itself is insufficient in pursuit of comfort.

In particular, in summer towel blankets, pajamas, and other bedding items, many innovations have been made, such as using crisp fiber fabric as the material, or pajamas with short sleeve designs. but,
It can be said that the comfort level was still insufficient. In order to improve this hot and humid environment, it is often seen that air conditioners are operated at night, but it goes without saying that relying on air conditioners is never a good idea when considering physical health. Especially at night, while sleeping, many people close their windows to prevent crime and insects.
Furthermore, bedding products are required to have high functionality such as high breathability and comfort.

On the other hand, bedding made of mesh-like fabric is also seen in order to achieve high breathability and comfort, but such bedding can cause skin and underwear to show through or give a chilly feeling. It also lacks adequate heat retention, so it is often avoided by the general public.

In the end, the current situation is that conventional bedding has not been able to achieve both high breathability, shielding properties, and appropriate heat retention. Never before have we seen bedding that combines these contradictory functions and is also rich in fashion.

[Problems to be Solved by the Invention] In view of the problems of the prior art as described above, the object of the present invention is to provide a material that has good ventilation characteristics and thus feels cool to the touch in the summer and has a silky texture. The bedding is highly functional, fashionable, and highly comfortable, as it prevents the inside from being seen through, and also has a novel fashion sense and rich appearance characteristics. We aim to provide the following.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration.

That is, the bedding of the present invention uses a special fabric material in which a large number of narrow sheets have a multilayer structure and are interconnected to allow ventilation through the gaps between adjacent narrow sheets. This is a line of bedding that is unique.

[Function] Hereinafter, the bedding of the present invention will be explained in more detail based on the drawings and the like.

In the present invention, bedding items typically include sheets, towel blankets, bedding fabrics/side duvets, duvet covers, pillowcases, pajamas, nightgowns, nightgowns, and yukata. Collectively, they are simply called bedding.

The present invention can be effectively applied to these bedding items, especially those for summer use.

FIG. 1 is a schematic diagram illustrating a towel blanket, which is a typical embodiment of the bedding according to the present invention.

In the towel blanket 1 shown in FIG. 1, the central part is a special fabric consisting of a large number of narrow sheets made of towel fabric, which have a multilayer structure and are interconnected to allow ventilation through the gaps between adjacent narrow sheets. Specifically, it consists of a multilayer fabric 2 made up of a large number of narrow sheets 3 and 3' made of, for example, cotton terry cloth, and around the periphery, for example, ordinary polyester fabric is used for reinforcement. 4
etc. are used. The reinforcing fabric 4 may be used not only in the peripheral area but also in the entire area.

FIG. 2 shows a pillow cover as another embodiment of the bedding according to the present invention, and the pillow cover 5 according to the present invention has a central portion made of the above-mentioned special fabric 2. A cord 6 is provided around the periphery.

Further, FIG. 3 shows 1 a yukata as another embodiment of the bedding according to the present invention, and the yukata 7 according to the present invention is mainly composed of the above-mentioned special fabric 2. This is what is being done.

As mentioned above, the bedding of the present invention uses a large number of narrow sheet-like materials, and these many narrow sheet-like materials exhibit a multilayer structure, and ventilation is allowed to flow through the gaps between adjacent narrow sheets. It is constructed using a special fabric material that can be linked together to form a sheet structure.

In the present invention, the narrow sheet may be a sheet having a width narrower than its length, and the width is not particularly limited, but preferably 11n111~
It is a sheet-like material such as a woven fabric, knitted fabric, non-woven fabric, or film having a width of 200 InIn, and a woven or knitted fabric is most preferable in terms of making the effects of the present invention more effective and workability during production.

The narrow sheet can be manufactured by weaving the sheet to a desired width using a ribbon loom or tape loom, or by weaving it on a wide loom and cutting it to the desired width using a cutter or the like on the loom or after weaving is completed. Furthermore, there is a method of obtaining a desired narrow woven fabric by interweaving easily soluble fibers at the boundary to be slit and then treating the easily soluble fibers in a liquid that dissolves them after weaving. A specific manufacturing method may be selected in consideration of the specifications of the desired narrow sheet.

A narrow sheet is not preferred because it is generally difficult to manufacture the sheet if the width is less than 1 #l111, and it is generally difficult to form a fabric with a multilayer structure.
In addition, when the width exceeds 200#I#I, there is a tendency that there is no significant difference in functionality and fashion, especially in terms of breathability, which is the most characteristic feature of the bedding of the present invention, compared to ordinary fabrics. Undesirable.

Therefore, a more preferable sheet width is 2rrw~
100mm, more preferably 3InIn to 30InI
n range. Furthermore, the average width is 1M to 2O
It may also be a narrow sheet with an irregular shape that exhibits an appropriate unevenness or waveform within the range of O-simplified. Roughly, its cross-sectional shape is not only a flat piece of dough, but also a ``he'' shape or a ``he'' shape.
It has a cross-sectional structure that is bent into a ``ri'' shape, an rWJ shape that is a combination of these, or a 〕, 〕, ``, f, ■, ~ shape, etc. You can.

Further, the structure of the narrow sheet may normally be a double layered sheet, but in some cases, it may be a cylindrical sheet or a sheet with a double structure such as a double woven fabric. Note that the sheet width refers to the width of both ends of the sheet in the short direction. However, for those with a bent or curved cross-sectional shape, this refers to the width at both ends in the bent or curved state. Furthermore, if it is cylindrical, it refers to the diameter at the core.

The narrow sheet is preferably made of a textile product such as a woven fabric, a knitted fabric, or a nonwoven fabric from the viewpoint of feel when used as bedding, and in this case, the fibers used for the narrow sheet base material include: , polyesters such as polyethylene terephthalate or copolymers thereof (e.g., copolymer components such as isophthalic acid and 5-sodium sulfoisophthalate), polybutylene terephthalate or copolymers thereof, nylon 6.11.12. Polyamides such as 66.610 and their copolymers, acrylic polymers, polyurethane, polyethylene, ultra-high molecular weight polyethylene,
Synthetic fibers such as polypropylene and its copolymers, polyvinyl alcohol, regenerated cellulose fibers such as rayon and cupro, semi-synthetic fibers such as acetate and triacetate, and natural fibers such as cotton, hemp, silk, and wool. Any of the fibers can be used, and these fibers may be used alone or in combination depending on the purpose, such as composite, blended, blended, twisted, mixed-woven, etc.

Among these, there are narrow sheets using composite yarns that are a combination of polyester fibers and polyamide fibers, and different fibers such as high-shrinkage fiber yarns and low-shrinkage fiber yarns that are made by copolymerizing isophthalic acid with polyester fibers. Narrow sheets made of composite yarns that can be combined with yarn, and water-sensitive fibers obtained by spinning polyvinyl alcohol with a low degree of frizz, exhibit shrinkage performance during processing and are bulky. By increasing the bulkiness (improved bulkiness) and obtaining good bulkiness and crispness, a higher level of comfort can be achieved by eliminating adhesion to the skin, improving breathability, and providing a smooth texture. This is preferable in that it is possible to Furthermore, as a method of obtaining bulkiness, there is also a method of constructing a narrow sheet using a single multifilament yarn subjected to bulk processing such as woolly processing.

In the present invention, a multilayer structure using narrow sheets is a superimposed structure made of a plurality of narrow sheets as shown in FIGS. 4A and B, FIGS. It is a general term for things that have a structure or a superimposed structure.

That is, FIG. 4A, FIG. 5A, and FIG. 6A all show the cross-sectional structure of the special fabric according to the present invention, which is formed by connecting a large number of narrow sheets, near the connecting joint of the narrow sheets. In FIG. 4A, the narrow sheets S1, S2, S3, S4, Ss, S6, and S7 are
This is a model of a multi-layered structure made up of multiple layers that are successively shifted in the width direction, just like a tiled roof or a roof. In Figure A, arrow C indicates the forward direction from the upper layer side to the lower layer side of the multilayer structure.

FIG. 5A shows, in addition to what is shown in FIG. 4A, narrow sheets S' 1, S'2, S! 3, s'4, S' s
, S' e, and S' 7 are overlapped one after another while shifting their positions, and another sheet material having a similar multilayer superimposed structure is used symmetrically on the back side to create a double multilayer structure. 1 shows a special fabric according to the present invention configured to exhibit the following characteristics.

FIG. 6A shows narrow sheets S1, S2, S3, S3, S3, S2, S3, S3, S3, S3, S2, S3, S2, S3, S3, S2, S3, S2, S3, S2, S3, S3, S2, S3, S2, S3, S2, S3, S2, S3, S2, S3, S2, S3, S3, S2, S3, S3, S2, S3, S2, S3, S3, S2, S3, S3, S2, S3, S2, S3, S2, S3, S2, S3, S2, S3, S2. Ss, S7
are connected to form one layer, and the narrow sheets s' 1, S' 2, S' 3, S' 4, S
This figure shows an embodiment in which separate layers consisting of 's, S' 6, and S' 7 are provided to provide a special fabric-like material with a multilayer structure.

In addition, Fig. 4B, Fig. 5B, and Fig. 6B are respectively
These correspond to Figure A, Figure 5 A1, Figure 6 A, and both are near the middle of adjacent connecting joints of the special fabric used in the bedding of the present invention, which is made up of a large number of connected narrow sheets. It is a model diagram showing the cross-sectional structure at (unconnected part), and narrow sheets S1, S2, S3, S4, S5, S6, S
7, and S' 1, S' 2. S' 3, S'
4, S's.

This is a model showing a state in which S' ty and S' 7 exist with appropriate gaps between adjacent narrow sheets.

The special fabric used in the bedding of the present invention has such a unique structure, so that air can pass through it in the direction of arrow a, as shown in the model diagrams of Figures 4 to 6B. In addition to realizing good ventilation characteristics, the watermark cannot be seen from the direction of the arrow, and at the same time has good breathability, it also has a shielding effect, and the overlapping or superimposed multilayer structure provides a suitable texture and comfort. This is possible.

Note that in FIGS. 4 and 5, the direction of arrow C indicates the forward direction of the overlapping structure.

FIG. 7 is a plan view showing as a model a typical structural example of one embodiment of the special fabric used in the bedding of the present invention shown in A and B of FIG. This shows a state in which narrow sheets S1, S2, S3, S4, S5, S6, and S7 are sewn together by a sewing machine at evenly spaced intervals and connected downward in the width direction to form a sheet. FIG.

In the same figure, dotted lines 8.9.10.11 are sewing machine suture lines, and the dd cross-sectional view is a cross-sectional view near the connecting joint (suture line portion) in Figures 4 to 6 A, and e-e The cross-sectional views correspond to the cross-sectional views in FIGS. 4 to 6B at a non-connecting portion near the middle of adjacent connecting joint portions.

Therefore, the multilayer structure using narrow sheets as used in the present invention is a general term indicating a superimposed structure or a stacked structure made of a plurality of narrow sheets as shown in FIGS. 4 to 6 A and B. It is. In other words, a fabric with a superimposed structure is a fabric formed by multiple narrow sheets overlapping each other, as shown in FIG. It is a fabric obtained by stacking two or more fabrics made of narrow sheets with a vertical cross-sectional structure in multiple layers. Therefore, the structure shown in FIG. 5 has both a superimposed structure and a superimposed structure.

There are various specific methods for forming a multilayer structure fabric using a large number of narrow sheets, and the method is not necessarily limited, but for example, a superimposed structure fabric as shown in FIGS. 4A and B As a method of forming a cylindrical material, a cylinder of an appropriate size whose surface is coated with a fluororesin such as polytetrafluoroethylene is coated with a thin cylinder impregnated with a water-soluble adhesive (such as polyvinyl alcohol-based or acrylic adhesive). width sea 1
~ are sequentially wound around a cylinder while rotating to a desired overlap width, dried, and adjacent narrow sheets are temporarily adhered to each other, then cut in the axial direction of the cylinder, and the narrow sheets form an overlapping structure. Obtain a temporary adhesive sheet. Then, the temporary adhesive fabric of the narrow sheets obtained in this way is machine-sewn at desired intervals in the forward direction of the stacked structure, that is, in the direction in which the narrow sheets do not turn up. The fabric of the present invention is sewn together at regular or random intervals, and then immersed in warm water to dissolve and remove the water-soluble glue used for temporary bonding. A superimposed structure fabric that can be used for orthoses can be obtained.

In addition, as a method for obtaining a temporary adhesive sheet, in addition to the method described above in which a narrow sheet is pre-impregnated with a water-soluble adhesive, the tape is wrapped around a cylinder in an undried state, and then dried and temporarily adhered. After wrapping the narrow sheet around a cylinder, apply a water-soluble glue mixture to the narrow sheet using a spray or brush.
There is a method of drying to obtain a temporary adhesive sheet. Further, as a method for bonding the narrow sheets together, a high frequency sewing machine, an ultrasonic sewing machine, or the like may be used. The method of joining the narrow sheets is not limited to sewing using a sewing machine.
Other methods such as adhesive bonding can also be used;
In the case of sewing, the fabric can be processed in the forward direction of the overlapping structure fabric, which is practical in that wrinkles can be prevented as much as possible and the process is simple.

Further, after temporary adhesion, when the narrow sheets are sewn together using a sewing machine to form a fabric, a seam reinforcing tape may be overlapped at the sewn portion and the reinforcing tape may be sewn together. Further, after forming into a fabric, in order to more firmly stabilize the superimposed structure, it is also preferable to perform ironing and/or hot pressing under the superimposed structure in the forward direction.

In addition, it may be preferable to subject the fabric to water-repellent treatment depending on the intended use. Water repellent treatment can be carried out by applying a suitable water repellent, such as silicone or fluorine, by spraying,
It can be easily applied by padding, dipping, coating, etc. Among these, the padding method is the best in that it can uniformly apply the water repellent to the fabric. During the padding process, it is effective to perform the process in the forward direction of the superimposed structure fabric in the same way as the sewing machine method described above in order to prevent the occurrence of wrinkles, and in these respects, the padding method is preferred.

Next, when sewing bedding such as sheets, towel blankets, pajamas, and yukatas using the above-mentioned special multilayered fabric according to the present invention, 100% of the fabric may be used, or , may be combined with other fabric materials.

In addition, for items such as sheets, pajamas, and towel blankets, it is preferable to construct narrow sheets of towel fabric, as this provides a comfortable feel to the touch and comfort to wear. Furthermore, if a narrow sheet made of such terry cloth has some problems, such as being too flexible and clinging to the body, or the formation of voids is insufficient, use terry cloth. In addition to the narrow sheets made of woven fabric, by using appropriate combinations such as alternating checkerboard patterns, narrow sheets made of regular knitted fabrics or non-woven fabrics that are more firmly formed and stiff than the terry cloth can be used as appropriate. It is also preferable to use them in combination.

When constructing the fabric of the present invention into bedding, it is practical to use it so that the forward direction of the multilayer structure substantially coincides with the direction from the top to the bottom of the bedding. When consideration is given to the appearance, etc., the use is not necessarily limited to such a usage, and it may be used in any suitable direction.

In addition, by appropriately combining a large number of narrow sheets with different colors, hues, or shades of color, you can create bedding with a new sense of fashion and design that has never been seen before. You can get similar results.

Furthermore, it is also possible to use narrow sheets made of different materials in appropriate combinations to create a product with multiple functions. For example, by combining a narrow sheet made of processed polyester yarn and a narrow sheet made of cotton, it is easy to obtain bedding that has both good crispness and good water absorption properties.

The bedding of the present invention uses the special fabric obtained as described above, which is cut and sewn into bedding, and is simple and excellent especially for summer use. To provide bedding that feels cool and comfortable to wear.

[Examples] Next, Examples will be shown, but this is for the purpose of clarifying the present invention, and the present invention is not limited to or restricted by these Examples.

Example A narrow sheet was obtained by weaving a towel fabric with a width of 7 m using real cotton threads for the warp and weft threads.

The narrow sheet was immersed in a water-soluble polyvinyl alcohol glue, and rolled up to the desired width while rotating the roll so that the surface overlapped a cylindrical roll coated with fluororesin and the width was 3 In#I. .

The sheet thus obtained was dried and cut in the axial direction of the roll to obtain a sheet temporarily adhered with the water-soluble glue described above.

Next, the sheet is sewn using a regular sewing machine at equal intervals of 20 m in the width direction of the narrow sheet and in the direction (forward direction) in which the narrow sheet does not turn up, to create a multilayered fabric with a superimposed structure. I got it.

A summer towel blanket as shown in FIG. 1 was sewn using the fabric. Note that a normal polyester fabric was used as the edging fabric to also serve as reinforcement. Next, immersion treatment was performed in hot water at 80°C to dissolve and remove the water-soluble glue.

In this way, a towel blanket was obtained in which narrow sheets having a width of 7 m were sewn in a continuous W4 manner with an overlapping width of 3 m and a superimposed structure as shown in FIGS. 4A and B, and a sewing pitch width of 20 M. When wearing such a towel blanket, it was found that on the day of the test, it was extremely hot and humid and it would have been difficult to sleep with a normal towel blanket, but by wearing the towel blanket of the present invention, it had excellent breathability and moisture permeability, and also had a moderate The heat retention and smooth texture provided an extremely comfortable feeling, making it an excellent summer towel blanket.

[Effect of the invention] By having the above-described structure, the bedding of the present invention has the following effects:
It has the following excellent functions and effects.

(1) Comfortable products with high breathability can be obtained without the skin being visible. It is especially suitable as summer bedding.

(2) It has high air permeability, as well as shielding properties, moisture permeability, and appropriate heat retention.

(3) The unevenness of the surface gives it a three-dimensional feel and a crisp feel.
It has a good texture and is comfortable to wear without being sticky to the skin.

(4) By combining different materials and different colors, it is a type of bedding that has never been seen before, which has multiple functions and can be made extremely fashionable.

(5) When used as a bedding fabric, it can maintain moisture permeability and air permeability with a filler such as wool cotton or synthetic cotton interposed inside. Of course, if a side fabric that wraps the batting is used separately on the inside, it is possible to completely prevent the batting fibers from flying out, and the above-mentioned features can be obtained.
