Abstract

PROBLEM TO BE SOLVED: To make urine and sweat absorbed and to prevent bedding, clothes and surrounding from being stained by using a water-permeable and water- diffusive texture for a surface fabric, using a water-impermeable and sir- permeable texture by water-repellent finishing for a back fabric, and arranging an intermediate fabric having a water absorbing property and preventing the backflow of moisture between both fabrics. SOLUTION: A knit fabric or a woven fabric made of a water-permeable and water-diffusive texture, preferably polyester or other synthetic fibers, and having a proper expansion/shrinkage property is used for a surface fabric 1 to be kept in direct contact with the skin. A knit fabric or a woven fabric made of a water-impermeable and air-permeable texture by water-repellent finishing, preferably polyester or other synthetic fibers, is used for a back fabric 2 to be kept in contact with the mattress of bedding. A nonwoven fabric or a knit fabric having a water absorbing property and having the required thickness to prevent the backflow of absorbed moisture is used for an intermediate fabric 3, and preferably a nonwoven fabric of synthetic fibers such as polyester and a warp-knit fabric such as raschel or tricot are used singularly or in lamination.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet, and more particularly, to a waterproof sheet laid on a mattress or mattress of bedding used by an elderly person, a sick person, etc. or an enuresis infant who may be incontinent.

[0002]

2. Description of the Related Art Conventionally, synthetic resin sheets and waterproof sheets have been laid on mattresses or mattresses of bedding used by elderly people, sick persons, etc. who may be incontinent or infants with enuresis so as not to stain the bedding. ing. Of these, the waterproof sheets are made to be impermeable by laminating the cloth with rubber or synthetic resin, so that the leaked urine can be applied to the bedding mattress or mattress laid under the waterproof sheets. I try not to soak.

[0003]

As described above, the waterproof sheets are similar to the synthetic resin sheets used for the same purpose.
By providing water impermeability, urine leaking out due to incontinence or nocturnal urine can be prevented from penetrating into the mattress or mattress of the bedding laid under the waterproof sheets, thereby preventing the bedding from being stained. On the other hand, there is a problem that the leaked urine accumulates on the waterproof sheets without being absorbed and wets the clothes of a sleeping person, or flows out along the waterproof sheets to stain the surroundings. In addition, since this kind of synthetic resin sheet and waterproof sheets are made only with water impermeability, they do not have air permeability, so people who are sleeping may sweat Cannot be absorbed, which causes not only discomfort but also a health problem. In particular, bedridden elderly people and sick people have a problem that they tend to have bedsores. In addition, since this kind of synthetic resin sheet or waterproof sheet does not have air permeability, in order to prevent bedsore, it has been widely used in recent years. When used for an air mat, there is a problem that the original effect of the air mat is lost.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the conventional synthetic sheets and waterproof sheets spread on mattresses and mattresses of bedding used by elderly people, sick persons, and infants with enuresis who may have incontinence. It is an object of the present invention to provide a waterproof sheet that absorbs urine and sweat leaked by urine, does not stain bedding, clothes of a sleeping person, and surroundings, and is less likely to cause bedsores.

[0005]

In order to achieve the above object, a waterproof sheet according to the present invention is provided by applying a water-permeable and water-diffusing cloth to a top cloth and a water-repellent finish to a back cloth. Water-permeable and air-permeable fabrics are used, and a middle cloth is provided between the front cloth and the back cloth, which has water absorption and prevents backflow of the absorbed water.

[0006] In this waterproof sheet, a water-permeable and water-diffusing cloth is used for the outer cloth in direct contact with the skin, so that urine or sweat leaked due to incontinence or night urine can be quickly removed. It absorbs and absorbs water, and it can be sent to the inner cloth to prevent backflow of the absorbed water and retained by the inner cloth, so that bedding, clothes of a sleeping person, and surroundings are not stained. In addition, the back cloth that prevents urine and sweat retained in the inner cloth from penetrating into the bedding or mattress under the waterproof sheets is made water-repellent to make it water-impermeable and ventilated. Since the cloth having the property is used, sweat and the like are not trapped, and the humidity can be appropriately maintained.

In this case, a nonwoven fabric, a warp knitted fabric such as Russell or Tricot can be used as the inner cloth.

Accordingly, a large space for holding urine and sweat leaked due to incontinence and night urine can be formed between the front cloth and the back cloth, and urine and sweat can be reliably held. In addition, the holding waterproof sheet itself can have a moderate cushioning property.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a waterproof sheet according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of a waterproof sheet according to the present invention. This waterproof sheet uses a water-permeable and water-diffusing cloth for the front cloth 1 and a water-impermeable and air-permeable cloth by subjecting the back cloth 2 to a water-repellent treatment. Between the cloth 1 and the back cloth 2, a middle cloth 3 having water absorbency and preventing backflow of the absorbed water is disposed, and is sewn 4 so as to be integrated so that they do not separate. The sewing method may be any quilting method, such as quilting as shown in the present embodiment, or any other method such as welding the outer peripheral edges of the three-layer cloths 1, 2, and 3.

[0011] The surface cloth 1 which is in direct contact with the skin is provided with a water-permeable and water-diffusing cloth, preferably polyester,
A knitted or woven fabric made of other synthetic fibers and having appropriate elasticity is used. Here, a knitted fabric made of a polyester fiber which has been subjected to a water-permeable diffusion process, more specifically, a polyester-modified process in which a hydrophilic group has been introduced by graft polymerization is used.

The backing cloth 2 which is in contact with the mattress or mattress of the bedding laid under the waterproof sheets is made of a cloth which is impermeable and breathable by subjecting the backing cloth to a water-repellent treatment, preferably polyester, A knitted or woven fabric made of other synthetic fibers is used.

The inner cloth 3 arranged between the front cloth 1 and the back cloth 2 includes
Nonwoven fabric or knitted fabric having a required thickness so as to have water absorption and prevent backflow of absorbed water, preferably nonwoven fabric of synthetic fiber such as polyester or warp knitted fabric such as Russell or Tricot alone Alternatively, these are laminated and used. In particular, when a warp knitted cloth such as Russell or Tricot is used, the ribs of the warp knitted cloth can prevent the top cloth 1 and the inner cloth 3 from adhering to each other. This makes it possible to reliably prevent the drained water from flowing back. Further, as the inner cloth 3, a sheet made of synthetic resin having breathability and cushioning property like a sponge can be used.

[0014] This waterproof sheet is used, similarly to the conventional waterproof sheet, by laying it on a mattress or mattress of bedding used by elderly people, sick persons, etc. or infants with enuresis who may be incontinent. Since the cloth 1 is made of a water-permeable and water-diffusing cloth, urine and sweat leaked due to incontinence and night urine are quickly absorbed,
Underneath, it is sent to the inner cloth 2 which has water absorbency and prevents the backflow of the absorbed water, and can be retained by the inner cloth 2 so that the leaked urine can be absorbed like a conventional waterproof sheet. It does not accumulate on the waterproof sheets and does not stain the bedding, the clothes of the sleeping person, and the surroundings, and can maintain a comfortable state for a long time. Become. In addition, the backing cloth 2 that prevents urine and sweat retained in the inner cloth 2 from penetrating into the bedding or mattress of the bedding laid under the waterproof sheets is water-impermeable by applying a water-repellent treatment, In addition, since the air-permeable cloth is used, sweat and the like are not trapped, the humidity can be appropriately maintained, and bedsore can be prevented. Furthermore, an air mat that has been widely used in recent years and that blows out pressurized air from the entire surface can be used in combination, and bedsores can be effectively prevented.

[0015]

According to the waterproof sheets of the present invention, since a permeable and water-diffusing cloth is used for the outer cloth in direct contact with the skin, urine leaked due to incontinence or nocturnal urine is used. Quickly absorbs sweat and sweat, has water absorption, sends it to the inner cloth that prevents backflow of the absorbed water, can be held by the inner cloth, stains bedding, sleeping clothes, and surroundings Therefore, a comfortable state can be maintained for a long time. In addition, the back cloth that prevents urine and sweat retained in the inner cloth from penetrating into the bedding or mattress under the waterproof sheets is made water-repellent to make it water-impermeable and ventilated. Air mat that can prevent sweat etc., keep humidity moderately, prevent bedsores, and effectively prevent bedsores, because we use fabrics with properties It is also possible to use them together.

Further, by using a non-woven fabric, a warp knitted fabric such as Russell or Tricot as the inner cloth, a large space for retaining urine or sweat leaked due to incontinence or night urine between the front cloth and the back cloth. A space can be formed, urine and sweat can be reliably held, and the holding waterproof sheets themselves,
It can have a moderate cushioning property.
