[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a water-absorbent material having a three-layer structure, more specifically to a water-absorbent cloth material suitable for use in wristbands, headbands, headbands, nightcaps, etc. to absorb sweat and moisture.

[0002]

[Prior art]

 Conventional wristbands and headbands are usually made of known knitted fabrics, and no particular consideration is given to sweat absorption and the like. In addition, the existing materials are simply used for night caps and the like, and moisture absorption is not considered.

[0003] On the other hand, incontinence diapers and bed sheets have a water-absorbing and hygroscopic cotton layer interposed and used for absorbing liquid. The surface cloth covers the water-absorbing non-woven fabric and the upper surface thereof. Then, a structure in which a thin cloth is layered is known.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned incontinence diapers and mats, the water-absorbent nonwoven fabric need only absorb liquid, and those that have absorbed liquid need to be replaced each time and are not used repeatedly.

In view of the above-mentioned circumstances, the present invention finds out, in particular, a super-water-absorbing property by using a highly water-absorbent and highly hygroscopic fiber, and a repeated use by evaporating absorbed water, whereby a wrist band, a headband, or a night cap is found. It is intended to be used for other purposes such as to eliminate discomfort caused by sweat and to accelerate the drying of hair after washing, thereby increasing the effect of absorbing water and expanding the fields of application.

[0006]

[Means for Solving the Problems] That is, in order to meet the above-mentioned object, the water-absorbent material of the present invention has an outer surface cloth forming a surface and a layered layer formed by polymerizing at least a part of the inner surface of the outer surface cloth. Water-absorbing, highly hygroscopic fiber A three-layer structure of a water-permeable thin cloth that covers the fiber layer and the upper surface of the fiber layer to protect the fiber layer and soften and smooth the upper surface of the fiber layer. Through a thin cloth, it is possible to absorb water for an instant.

According to a second aspect of the present invention, the above-mentioned constitution is embodied, wherein the outer cloth is a knitted cloth, and a fiber layer made of highly water-absorbing and highly hygroscopic fibers is made into a water-absorbent polymer. It is not a non-woven fabric layer made of woven fibers, but a water-permeable thin fabric made of a synthetic fiber filament.

Further, the invention according to claim 3 relates to a more specific structure, wherein a cotton woven cloth such as a towel cloth is used as the outer cloth, and a non-woven fabric layer of fibers made of polyacrylic acid sodium salt is polymerized on a part of the inner surface. , And the upper surface is covered with a tricot thin cloth made of synthetic fiber filaments.

[0009]

[Action]

 According to the water-absorbent material of the present invention, when it is used for a headband, a wristband, etc., sweat is absorbed into the water-absorbent fiber layer through a thin cloth, but the fiber layer has high water-absorption property and high hygroscopicity. , The water is absorbed at an early stage instantaneously, the absorbed water does not escape even if pressure is applied, and it is possible to continue high water absorption even by drying, so that comfortable use can be continued, replacement of the fiber layer, etc. Eliminate the waste of. Moreover, when it is used as a night cap, by washing the hair and using the night cap as it is, the washing water is absorbed and the hair is not dried by a dryer or the like.

[0010]

[Embodiment of the invention]

 Hereinafter, specific embodiments of the water absorbent material of the present invention will be described with reference to the accompanying drawings.

1, 2 and 3 are examples of using the water absorbent material having a three-layer structure according to the present invention for a wrist band (FIG. 1), a headband (FIG. 2) and a hair band (FIG. 3). In each of these drawings, 1 is an outer surface fabric that forms a surface and exerts a design effect as necessary, 2 is a high water-absorbing property and high hygroscopic property in which a polymer layer is formed on the whole or part of the inner surface of the outer surface fabric 1. Reference numeral 3 denotes a fiber layer made of fibers, and 3 is a soft and smooth water-permeable thin cloth that protects the upper surface of the fiber layer 2 and improves the touch when the upper surface contacts the skin.

As the outer surface fabric forming the surface, a normal knitted or woven fabric made of known fibers is used, and a pattern, a patch pattern, or the like is formed on the outer surface side at any time to enhance the design effect. It is also advantageous to use depending on the application and purpose, and above all, a knitted or woven fabric having hygroscopicity such as cotton fabric is useful. However, of course, this does not preclude the use of knitted fabrics made of synthetic fibers.

The fiber layer 2 made of highly water-absorbent and highly hygroscopic fibers, which is polymerized and laminated in the middle, has a higher water-absorbing and moisture-absorbing rate and a larger water-absorbing and moisture-absorbing amount than the conventional water-absorbing and moisture-absorbing fiber layers. And, it is a layer that has the property that water that has once absorbed at high speed does not escape even when pressure is applied, and that it can be highly absorbed by repeating after drying. Specifically, it is used for water-absorbing polymers. For example, it is made of soda salt of polyacrylic acid and made to have the same function as the water-absorbent resin. Further, bridge-type polyalkylene oxide and bridge-type cellulose can also be used by forming them into fibers.

This highly water-absorbing and highly hygroscopic fiber layer may be used in the state of fiber cotton, or may be used in the state of non-woven cloth or knitted cloth, but it is used as a fiber web and needle punched. It is most practical to apply it in a non-woven fabric state. In this case, the basis weight of the fibrous web can be adjusted from very thin to very thick depending on the purpose of use.

Further, it is essential that the thin cloth 3 covering the upper surface of the fiber layer 2 as an intermediate layer has water permeability. As the thin cloth 3, a tricot knitted cloth made of synthetic fiber filaments such as nylon, polyester and polypropylene is usually used. Needless to say, not only tricot knitted fabrics but also knitted fabrics having a relatively coarse structure can be used, but a tricot thin film having water repellency and hydrophobicity from the viewpoint of flexibility and smoothness. It is most effective to use cloth. The tricot knitted fabric is sometimes raised and raised.

Thus, according to the present invention, the outer cloth 1, the fiber layer 2 and the water-permeable thin cloth 3 constitute a main part of the water-absorbent material, and the wristband 10 shown in FIG. 1 has a predetermined length and width. The outer surface of the cloth 1 is brushed, and a cloth fastener 4 having a hook portion is attached to one end of the outer cloth 1, and after the cloth fastener 4 is attached to the wrist, the hook portion of the cloth fastener 4 is adjusted by adjusting the length. The outer cloth 1 can be mounted by being locked at a required position on the outer raised surface.

In addition, in the headband 11 shown in FIG. 2, the outer surface cloth of the water-absorbent material is formed into an elongated shape and provided with the above-mentioned three-layer structure in the center portion in the length direction, and both sides thereof are bound. It has a two-layer structure of the outer cloth 1 and the thin cloth 3 for ease of use. In the figure, 5 is a marker cloth attached to the outer surface side central portion of the outer cloth 1.

Similarly, in the annular hair band 12 shown in FIG. 3, the three-layer structure is arranged at the sweat and moisture generating portions. In this case, the other parts except the three-layer structure part are formed only by the outer cloth 1. Therefore, the outer cloth 1 has a relatively thick layer, and, for example, a bag-shaped pile cloth in which towel cloth having a pile is formed into a bag shape is used. 6 is a marker cloth.

Although the respective embodiments using the water-absorbent material of the present invention have been described above, the usage modes of the water-absorbent material of the present invention are not limited to the above, and other various products such as incontinence sheets and towels can be appropriately used. It is possible to use, and the configurations of the outer cloth 1, the fiber layer 2 and the type of the thin cloth 3 are selected at any time according to each aspect.

[0020]

[Effect of the invention]

 The present invention utilizes the fiber layer made of highly water-absorbing and highly hygroscopic fibers as described above, and this is inserted between the outer cloth and the thin cloth. Although the water absorbs and absorbs moisture into the fiber layer, the fiber layer absorbs and absorbs a large amount of water in a moment because it absorbs and absorbs water at a high rate. It has a smoothness and retains a good feel to the touch, and since once absorbed water does not escape even with a slight pressure, it does not wet the surroundings and has a good use effect. In addition, the water-absorbent material of the present invention can repeatedly and highly absorb water after being dried, and has a stable water absorption rate and an effect of doubling the effect of each product. In particular, when used as a night cap, it has an advantage that it absorbs moisture during hair washing at night and during sleep, and omits drying after washing hair.
