Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a laminated fabric suitable for diaper covers and various sheets.

[Conventional technology and problems to be solved]

BACKGROUND ART Hitherto, diaper covers have been known in which waterproof woven and knitted fabrics made by laminating vinyl chloride film or polyurethane film on various woven or knitted fabrics and woven or knitted fabrics are sewn together. Although such diaper covers are highly waterproof and highly effective at preventing leakage, they are not breathable, absorbent, or retain water, making them uncomfortable to wear, and especially when the diaper gets wet, it can cause a strong feeling of coldness. Not only does it cause discomfort to infants, but it also has the disadvantage of making the skin stuffy and being unhygienic.

In addition, as a diaper cover with improved comfort,
It is also known that a knitted fabric covered with a moisture permeable resin layer and a knitted fabric fabric are sewn together. Although this kind of diaper cover has a low degree of stuffiness and prevents water from leaking, if the diaper gets wet with excrement, water absorption and water retention can only be achieved through woven and knitted fabrics. To make the skin surface that comes into contact with the diaper comfortable, water absorption and water retention are still insufficient, resulting in cold sensations and
The drawback was that the discomfort could not be alleviated.

Moreover, since various types of sheets are mainly made of thin cotton, they have the drawback of not only poor water absorption and water retention properties, but also poor heat retention properties.

The present invention was made to solve the above problems, and provides a laminated fabric that is comfortable to wear, has excellent washability, and can be used repeatedly.

[Means for solving problems]

In the laminated fabric according to the present invention, a surface fabric made of hydrophobic fibers and a base fabric covered with a moisture-permeable synthetic resin layer are laminated with an intermediate fabric interposed therebetween, and the intermediate fabric is made of ultrafine synthetic fibers. Both sides of the cotton-like sheet, which is a cotton-like aggregate, are covered with a fabric made of hydrophilic fibers. The present invention solves the above problems by employing the above configuration.

[Effect]

The outer fabric made of hydrophobic synthetic fibers has no affinity with small water, sweat, etc., so even when it comes in contact with the skin, it always feels dry and dry. Further, even if the outer fabric gets wet with small water, etc., the water is quickly absorbed and retained by the intermediate fabric, which has water absorption and water retention properties due to its hydrophobic property. That is, the intermediate fabric is made by covering both sides of a cotton-like sheet made of ultra-fine synthetic fibers with fabrics made of hydrophilic fibers such as natural fibers, and fabrics made of hydrophilic fibers have a high affinity for water. The small water is quickly absorbed by capillary action, and the ultrafine synthetic fibers have a large surface area, and the cotton-like sheet has many fiber gaps, so it has high water retention.

On the other hand, since the base fabric is coated with a moisture-permeable synthetic resin layer, water absorbed and retained by the intermediate fabric is difficult to leak, but water becomes vapor and is gradually released.

In addition, because the outer fabric, intermediate fabric, and base fabric are laminated and integrated, they are durable, and the laminated structure will not collapse even after repeated washing.
It is mainly made of hydrophobic synthetic fibers, so it does not drain easily.
It has great drying properties.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A diaper cover which is an embodiment of the present invention will be described below based on the drawings.

In the drawing, reference numeral 1 indicates a surface fabric made of hydrophobic synthetic fibers, and this surface fabric 1 is made of water-repellent polyester synthetic fibers knitted into a mesh shape to improve breathability and water permeability. The mesh fabric is used.

In addition, various materials can be used for the outer fabric, including various hydrophobic synthetic fibers such as polyester fibers and polypropylene fibers, and natural fibers treated with one or more types of water-repellent such as silicone resin and fluororesin. Synthetic fibers that have been treated to be water repellent as described above are preferable, and in order to improve the feeling of contact with the skin, breathability, and water permeability, coarsely woven or knitted fabrics, especially mesh fabrics, are preferable. .

The base fabric 2 is knitted from nylon fibers, and one side of the base fabric 2 is coated with a polyurethane resin film having a large number of fine pores of about 5 to 10 microns as a moisture permeable synthetic resin layer 3. The moisture becomes water vapor and is gradually released through the fine holes of the moisture-permeable synthetic resin layer 3 and the base fabric 2, while at the same time preventing the leakage of small water and the like.

Natural fibers such as cotton and wool can also be used as the base fabric, but in order to speed up the drying of the cover, various synthetic fibers such as polyester fibers, acrylic fibers, and polyurethane fibers, especially those treated with water-repellent treatment, can be used. synthetic fibers are preferred. Furthermore, various materials such as acrylic resin and polyester resin can be used as the material for the moisture permeable synthetic resin layer. The moisture-permeable synthetic resin layer may be formed by coating the base fabric with a hydrophilic synthetic resin, or by adhering a hydrophilic synthetic resin film, a polyurethane resin film having microporous pores, or an acrylic resin film. After applying the resin solution to the base fabric, the fabric may be immersed in water containing a hydrophilic organic solvent before drying to form microporous pores in the synthetic resin layer.

When bonding synthetic resin films, bonding the entire surface will reduce the moisture permeability effect, so point bonding or linear bonding is preferable in order to ensure texture, flexibility, and moisture permeability. Those bonded with a mold adhesive are preferable because they cause less fatigue even after repeated use.

Further, both sides of the base fabric may be coated with a moisture-permeable synthetic resin layer, but it is preferable that at least one side of the base fabric in contact with the intermediate fabric 4 described later is coated.

An intermediate fabric 4 having water-absorbing and water-retaining properties is arranged between the outer fabric 1 and the base fabric 2 having a moisture-permeable synthetic resin layer 3 on the inner surface.
consists of a cotton-like sheet 5 made into a cotton-like aggregate using ultrafine synthetic fibers such as polyester or nylon, and a fabric 6 made of hydrophilic fibers such as cotton covering both sides of this cotton-like sheet 5. The cotton-like sheet 5 and the hydrophilic fiber fabric 6 are embroidered and knitted to form a quilt structure.

The ultrafine synthetic fiber is not limited to the above materials. In addition, in order to increase the water absorption and water retention properties of the cotton-like sheet,
Fibers with a fineness of 1 denier or less are preferred. When the denier is 1 denier or less, the surface area of the cotton-like sheet becomes significantly large, many fine fiber gaps are formed, and the water absorption and water retention properties are significantly increased.

Further, the hydrophilic fibers are not limited to cotton, and may be hydrophilic ones, such as natural fibers such as wool or linen, or synthetic fibers treated to make them hydrophilic.

The cotton-like sheet may be covered with a hydrophilic fiber fabric, and may be sewn tightly together,
By having a quilt structure, water absorption and water retention can be increased, and deformation due to washing can be prevented.

In order to increase the rate of water absorption, these intermediate fabrics are treated with water absorption processing using hydrophilic resins and surfactants through cross-linking and dipping treatments, making them even more active in absorbing and retaining water. Alternatively, the super absorbent resin may be mixed into the intermediate fabric.

The outer fabric 1 and the base fabric 2 are adhered and sewn in a dotted manner via the intermediate fabric 4, thereby forming a laminated fabric that is integrally laminated. Note that the adhesive means is not necessarily necessary.
It may be sewn to increase the integrity of the laminated fabric.

The water absorption amount and water retention amount of the laminated fabric can be arbitrarily adjusted by changing the thickness and amount of the ultrafine synthetic fibers and the thickness of the cotton-like sheet made of the ultrafine synthetic fibers. For example, for infants under 2 years old, the amount of water per time is about 80 to 90 c.c., and the number of diaper changes per day is 7 to 8 times. Therefore, based on this value, we investigated the relationship between the water retention amount and the thickness of the cotton-like sheet, and found that if approximately 70g of ultrafine polyester synthetic fiber of 1 denier or less is used and the apparent thickness of the cotton-like sheet is 2 to 3 mm, It holds about 80-90 c.c., which is a small amount of water per use. Therefore, by simply increasing the thickness of the cotton-like sheet to 3 to 4 mm, the laminated fabric as a whole can retain two small amounts of water,
Therefore, the number of diaper changes can be reduced to about 1/2.

As shown in Fig. 2, the laminated fabric having the above structure is cut into a size and shape suitable for diapers, and an elastic band 11 is placed on the inside of the upper part to improve adhesion to the waist, etc. are sewn, and cover pieces 12, 12 for covering the waist and the like are attached to both sides of the upper part by sewing means. The covering pieces 12, 12
Needle pieces 13, 13 are attached to the inner end of the
The outer surfaces of the covering pieces 12, 12 are covered with pile pieces 14, 1.
4 is provided, and the needle pieces 13, 13 and the pile pieces 14, 14 constitute a surface fastener.

In addition, on both sides of the laminated fabric located in the crotch area,
In order to prevent water from leaking from the crotch area, side pieces 15, 15 are provided, and pile pieces 14, 14 provided on the outer surface of the cover pieces 12, 12 are provided at both ends of the lower part of the laminated fabric. Needle pieces 16, 16 intertwined with each other are attached.

The above-mentioned cover has the function of the laminated fabric both as a diaper and as a diaper cover.
It is not necessary to use a diaper and a diaper cover separately as in the conventional case, and one cover can be conveniently used as a cover with a diaper that has two functions.

[Effect of idea]

In this invention, the outer fabric that comes in contact with the skin is made of hydrophobic fibers, so even if it gets wet with water or sweat, it always feels dry and dry and does not cause discomfort. This effect is particularly great when the outer fabric is a mesh fabric that has been treated to be water repellent.

In addition, the intermediate fabric has a cotton-like sheet of ultra-fine synthetic fiber with high water retention, and has a high affinity for water.
It is coated with a fabric made of hydrophilic fibers that quickly absorbs small water etc. by capillary action, and small water etc. are absorbed through the fabric made of hydrophilic fibers by forming a cotton-like sheet which is a cotton-like aggregate of ultra-fine synthetic fibers. Because it retains water, it has high water absorption and water retention properties, and does not give a cold feeling to the skin.

On the other hand, the base fabric is covered with a synthetic resin layer,
Although small water etc. do not leak to the outside, the synthetic resin layer is moisture permeable, and the moisture etc. turns into water vapor and is evaporated and released, so the skin does not become stuffy. Coupled with this effect, it is comfortable to wear.

In addition, the cotton-like sheet is covered with a hydrophilic fiber fabric and is laminated together with the outer fabric and base fabric, and is mainly made of hydrophobic synthetic fibers, so it has good washability and drying properties. , not only can be used repeatedly, but also hygienic. In addition, water absorption and water retention can be adjusted simply by changing the thickness of the cotton-like sheet, and when used as a diaper cover, one cover can function as a diaper and a diaper cover at the same time.
This is convenient because the number of replacements can be reduced.

In addition, the cotton-like sheet made of ultra-fine fibers has great heat retention properties, and as mentioned above, has water absorption and water retention properties, so the laminated fabric of the present invention is suitable not only for babies but also for hospitals and bedridden elderly people. sheets,
It is also suitable as a sweat mat.
