Field of the Invention The present invention relates to a water-disintegratable non-woven fabric and a laminate thereof, and more particularly, to contacting sanitary products such as sanitary products and disposable diapers with a limited amount of water or aqueous solution during use. The present invention relates to a water-disintegratable nonwoven fabric and a laminate thereof, which is free from the destruction of the above-mentioned material due to dissolution and the phenomenon of permeation to the back surface and is disintegrated into a state capable of being discharged in water in an amount exceeding the absorption capacity. Further, as a method for treating waste after it is used, in addition to the above-mentioned discharge treatment into sewage, a method for degrading microorganisms by burial in the ground, or 4000 to 5000 kcal which is almost the same as natural fiber.
Since it has a low calorific value, it can be incinerated by existing incinerators.

Description of the Related Art Conventionally, when contacted with a limited amount of water at the time of use, it has a function as a product without causing structural destruction of the product due to dissolution of raw materials, There was no polymer system that could disintegrate and be released, and that could also be biodegraded by microorganisms in large amounts. Therefore, the basic common structure of sanitary items such as sanitary items and disposable diapers is (1) a polyethylene net for protecting the surface and keeping the skin contact surface dry. (2) An absorption layer for absorbing water or blood. (3) A polyethylene film for preventing penetration into clothes. Since the polyethylene net and film do not disintegrate, the whole sanitary article is very filthy and absorbs excrement, and is transported and treated together with general household waste, especially when transported. At that time, the scattering of excrement due to the rupture of the packaging bag became a hygiene problem for workers and began to attract social attention.

目的とする。As described above, sanitary products such as sanitary products and disposable diapers that are commercially available in the past have an existing structure in order to satisfy the functions required by their usage. However, the reason for this is that no polymer system satisfying the above-mentioned conditions has been found. Therefore, the present invention satisfies the above-mentioned functions as sanitary products such as sanitary products and disposable diapers, and at the same time solves the problem of waste treatment, and finally, most of the components are biodegraded by microorganisms, and at the sewage treatment plant. An object of the present invention is to provide a water-disintegratable nonwoven fabric laminate that can be treated.

とができる。According to the first aspect of the invention, the degree of saponification is 80
-88%, polyvinyl alcohol having an average degree of polymerization of 500-1000 was prepared to a thickness of 50-100 microns by T-die method, and a film having small holes with a diameter of 1-3 mm was processed on the entire surface of a polyester or polyolefin fiber sheet. By heating and adhering, a water-disintegratable polyester or polyolefin fiber nonwoven fabric that easily permeates water and an aqueous solution can be obtained. The nonwoven fabric obtained in the present invention is very interesting because it easily permeates water and aqueous solution, and due to the water repellency of the polyester or polyolefin fiber, a dry state can be obtained even in contact with water and aqueous solution. Applications are provided. That is, when using an existing disposable diaper, a very unhygienic disposal method is used, in which stool is wrapped in the disposable diaper itself and is transported and treated together with general household waste. When the resulting water-disintegratable nonwoven fabric is inserted into an existing paper diaper and used as a stool liner, urine is easily permeated and absorbed by the paper diaper, but stool is used as a liner for thin water-disintegration of the present invention. Since it remains on the non-woven fabric, if it is wrapped and put in the water of the toilet, the whole becomes a slurry and can be discharged. Further, the used paper diaper can be repeatedly used by inserting the water-disintegrating nonwoven fabric of the first aspect of the present invention until it becomes soiled. If the disposable diaper becomes unusable, it can be disposed of together with general household waste, which can solve the problem of hygiene.

A water-disintegratable non-woven fabric formed by heating and adhering to a fibrous sheet is overlaid with the surface of the polyvinyl alcohol film inside, and a pulp fibrous sheet containing a super absorbent polymer is inserted in the middle, and the periphery is To obtain a water-disintegratable non-woven fabric laminate which has the functions of an existing menstrual band and a disposable diaper by heating and adhering, and is put into the water of a toilet after use to be disintegrated into a slurry state and can be discharged. You can In the laminate of the present invention, the non-woven fabric surface of the polyvinyl alcohol film having small pores has an effect of absorbing and transmitting water, and the non-woven fabric surface of the non-woven fabric of polyvinyl alcohol film has a leakproof property. It is effective, and the polyvinyl alcohol film itself can be an adhesive for the laminate.

便用ライナーとして前記と同等の効果が得られた。Example 1 A mixture of 100 parts by weight of polyvinyl alcohol having a saponification degree of 88% and an average degree of polymerization of 500 and 15 parts by weight of polyethylene glycol having an average molecular weight of 400 is heated and melted to form a film having a thickness of 50 μm by a T-die method. Got Small holes having a diameter of about 2 mm were opened at intervals of 5 mm on the entire surface of this film, and heated and bonded to a polyester fiber sheet having a basis weight of 50 g / m 2 to obtain a water-disintegratable non-woven fabric excellent in water permeability. The structure of the nonwoven fabric of Example 1 is shown in FIG. A practical test was conducted by inserting the surface of the polyvinyl alcohol film of the non-woven fabric into the portion of the existing inner surface of the disposable diaper that comes into contact with the body. In the case of only urine, the urine is rapidly absorbed by the absorbent layer of the disposable diaper through the small holes and the surface becomes dry,
It was possible to use it while maintaining the original shape as in the past. In the case of stool, when wrapped with the non-woven fabric and put in the water of a toilet, it could be collapsed into a slurry and discharged, and the used diaper could be prevented from being soiled to the extent that it could be reused again. Of course, once used diapers are
Since it does not release water even under pressure, it can be transported and treated at the same time as general household waste. In this example, a polyethylene fiber sheet was used instead of the polyester fiber sheet, but the same effect as the above was obtained as a stool liner for a disposable diaper.

A water-disintegratable nonwoven fabric obtained by heating and adhering a polyvinyl alcohol film having a continuous flat surface without heat treatment is stacked as shown in FIG. By such an operation, a menstrual band and a disposable diaper were prepared. The sanitary belt and the disposable diaper having such a laminated structure have the same functions as existing products, and when they are put into the water of a toilet, they are collapsed into a slurry of fibers and can be discharged. Liquids such as blood and urine are rapidly absorbed by the pulp fiber sheet of (3) through the small holes of the polyvinyl alcohol film of (2) shown in FIG.
The polyvinyl alcohol film of (4) was prevented from being dissolved and showed complete leakproofness. Since the liquid has a high absorption rate and the surface is a hydrophobic fiber, it is possible to keep the surface dry during use.
