る。2. Description of the Related Art Conventionally, a sanitary material such as a paper diaper has an outermost layer (back sheet) integrally formed with a leak-proof sheet made of a resin film. However, this layer is rough and hard to touch, and this inconvenience is caused. In order to improve it, it is also practiced to further overlay the outer surface with a non-woven fabric. However, such a structure is not preferable in terms of design because the nonwoven fabric is separated from the film. When manufacturing such a product, the non-woven fabric and the film are manufactured by manufacturing the sanitary material while continuously supplying the non-woven fabric and the film individually.
Since each of them is required to have its own strength, there is an inconvenience that the weight of these materials increases and it goes against the weight reduction of the product.

の鮮明さなどの点で必ずしも満足し得るものではない。As the back sheet of sanitary material, a plain white sheet is also used from the standpoint of cleanliness, but a pattern may be printed on the surface of the film or the non-woven fabric in order to give a high-class feeling and a design effect. Has been done. Since the texture of the film remains as it is when the pattern is printed on the film, it is far from a high-class feeling, and the one printed on the surface of the non-woven fabric is not always satisfactory in terms of printing clarity.

水フイルムであってもよい。The thermoplastic film must be colored in a color different from that of the nonwoven fabric. When the film is uncolored or has the same color as the nonwoven fabric, it is difficult to give a different color pattern to the thermocompression bonding part. The color of the film is not particularly limited, and the density is not particularly limited. The colorant may be highly transparent such as a dye, or may be highly opaque such as a pigment, but when a highly transparent colorant is used, the color of the internal absorption layer from the colored pattern part Depending on the application, it is preferable to use a coloring agent having high opacity, because it may be transparent and may be seen. Coloring of the film can be obtained by melt molding a resin mixed with a colorant as is conventionally done. The thickness of the film is also not particularly limited, but as the thickness increases, the flexibility decreases, and the resulting sanitary material becomes harder in texture, and when the thickness decreases, problems such as pinholes may occur due to thermocompression bonding with the nonwoven fabric. As a guide, it will be 10-5
The range is preferably about 0 μm. Further, the thermoplastic film may be a microporous moisture permeable waterproof film other than the non-porous film.

る。The nonwoven fabric laminated on the film has a fiber diameter of 1
It is composed of a thermoplastic fiber of 0 μm or less, preferably 5 μm or less. The fiber diameter is important for obtaining the opacity of the non-woven fabric. For example, a fiber having a fiber diameter of 3 μm is 100 times as long as a fiber of 30 μm having the same weight, and the projected area (shadow area) is 10 times. The area becomes large. Moreover, since the radius of curvature of the fiber surface is 1/10 and the fiber surface area is 10 times, diffuse reflection occurs on the fiber surface, and the concealment effect becomes higher than the actual concealment area. In addition, the fact that the fiber diameter is small also has the effect of making the texture of the non-woven fabric soft, and the resulting leak-proof sheet or sanitary material has a soft texture.

となってしまう。The non-woven fabric used in the present invention must be composed of thermoplastic fibers. If the fibers are not thermoplastic, the crimped portion will not be sufficiently transparent and will not have a colored pattern when thermocompression-bonded to the film. It becomes unclear. Further, when the transparency of the non-woven fabric is high, the difference in transparency between the thermocompression bonded portion and the non-pressure bonded portion becomes small, and similarly the colored pattern becomes unclear.

ｇ／m2程度の範囲であることが好ましい。The above-mentioned non-woven fabric composed of thermoplastic fibers can be produced by a melt blown method, a spun bond method, a dry method using a split type fiber, or the like. A particularly effective method in the present invention is a melt blown method. There is a law. The non-woven fabric obtained by the melt blown method has a small constituent fiber diameter, is randomly deposited, and has a high density, so that even a small basis weight has a high concealing property and a good thermocompression bonding property with a film. In particular, it is preferable to use a polyolefin-based resin because the nonwoven fabric is easy and inexpensive to manufacture, and has water resistance (waterproofness) and water repellency. The non-woven fabric is
It is preferable that the morphology is previously stabilized by embossing or the like within a range that does not impair the opacity. The basis weight of the nonwoven fabric is not particularly limited, but when the basis weight is small, the hiding property is likely to decrease even if the fiber diameter is reduced, it is difficult to obtain a uniform nonwoven fabric, and when the basis weight is large, a leak-proof sheet is used. 15 to 50 because the thickness is too thick and the compactness is poor and the texture tends to be hard.
It is preferably in the range of about g / m 2 .

果も有する。As a method for laminating and crimping a thermoplastic film and a non-woven fabric, a film and a non-woven fabric, which are separately prepared, are laminated and thermo-compression-bonded in a pattern by ultrasonic waves or a heat embossing calendar. May be laminated by extrusion and then pressure-bonded with a cooling roll having an uneven pattern, and further, a non-woven fabric may be directly formed on the film by a melt blown method or the like and thermocompression-bonded. What is important in the present invention is that the non-woven fabric becomes substantially film-like and has transparency in the crimped portion. By making the non-woven fabric transparent, the color of the colored film on the back surface can be seen through at that portion, and a clear colored pattern can be obtained. Also,
By making the non-woven fabric into a semi-film at the pressure-bonded portion, it also has the effect of improving the durability such as abrasion resistance of the non-woven fabric made of fibers having a relatively small fiber strength such as a melt blown non-woven fabric.

独特の意匠効果が得られる。If necessary, the non-woven fabric may be colored or provided with a print pattern in a color different from that of the colored film. When a pattern is applied to the non-woven fabric, a unique design effect can be obtained from the difference in color and texture between the colored pattern portion obtained by forming the non-woven fabric into a semi-film by thermocompression bonding and the colored portion of the non-woven fabric.

ものであった。A paper diaper was manufactured by using each of the leakproof sheets with the non-woven fabric side as the outside. All of the obtained paper diapers using the leak-proof sheets A to C had a soft texture, were excellent in wearing feeling, and had sufficient durability. The sheet using the leak-proof sheet D was flexible, but the non-woven fabric and the film were not sufficiently adhered to each other, and some peeling occurred during wearing. In addition, the sheet using the leakproof sheet E was thick and lacked in flexibility due to the large basis weight of the nonwoven fabric.

て不明瞭な着色模様しか得られなかった。Regarding the appearance of the disposable diaper, the sheets using the leakproof sheets A, B and E have a good concealing property by the non-woven fabric, and almost no color of the film can be seen through other than the pressure-bonded portion, and the film is not visible at the pressure-bonded portion. A blue color was seen through and a colored pattern with a clear outline was observed. On the other hand, in the case where the sheet C for leakage prevention is used, the blue color of the film can be seen through at the pressure-bonded portion, but the blue color of the film can be generally seen through the area other than the pressure-bonded portion, and only a blurred color pattern is obtained. I couldn't do it. Further, with the sheet for leakage prevention D, the blue color of the film can be seen through as a whole, but since the fibers are not formed into a film even at the pressure-bonding portion, the blue color of the film is not seen through so much and the film is thin as a whole. Only a blue pattern was seen and only a very unclear colored pattern was obtained.

Moreover, since the non-woven fabric and the film of the present invention are integrated at the thermocompression bonding portion, the non-woven fabric and the film are not separated from each other, have sufficient durability, and have a small basis weight. It has enough strength to be supplied to the manufacturing process of sanitary materials, and it is possible to make the sanitary material products lightweight and slim. Further, since it has a clear colored pattern corresponding to the shape of the thermocompression bonded portion, it has a design effect that cannot be obtained by printing on the surface of the non-woven fabric, and can be a product with high added value.
