In the present invention, the term water-absorbing resin means a water-absorbing resin having a relatively low water-absorbing performance, a water-absorbing fiber having a relatively low water-absorbing performance, a highly water-absorbing resin having a high water-absorbing performance, or a highly water-absorbing fiber having a high water-absorbing performance. In addition to the highly water-absorbing resin as a product, the highly water-absorbing resin as a waste material can be used. However, it is preferable to use a material having high water absorption because the amount used can be reduced. In the case of a water-absorbing fiber and a highly water-absorbing fiber, they are used after being cut or crushed into appropriate dimensions.
In the present invention, the superabsorbent resin is also called a superabsorbent polymer, and the superabsorbent resin used in the present invention absorbs about 30 to 100 times its own weight of water by artificial urine. However, it is preferable that the resin can retain its shape. Examples of such highly water-absorbent resins include saponified copolymers of vinyl esters and ethylenically unsaturated carboxylic acids or derivatives thereof, graft polymers of starch and acrylic acid, crosslinked products of polyacrylic acid, and vinyl alcohol. And a copolymer of acrylic acid, a partial hydrolyzate of polyacrylonitrile, a crosslinked product of carboxymethyl cellulose, a crosslinked product of polyethylene glycol, a chitosan salt or a pullulan gel. These are used alone or in admixture of two or more in the water-absorbing material powder.

  In the present invention, as the superabsorbent resin, for example, a superabsorbent resin-containing material or superabsorbent fiber or a pulverized product thereof recovered from a disposable diaper, incontinence pad or sanitary napkin, waste paper diaper, etc. can do. Such recovered superabsorbent resin has a water absorption capacity of 10 to 30 g / g as compared to artificial urine, and its water absorption performance is poor. However, hygiene sheets such as paper diapers and animal sheets have such a water absorption capacity. It was found that the effect can be used sufficiently. The particle size of the superabsorbent resin used is preferably 50 to 500 μm.

  In the present invention, the water-absorbing material powder has a relatively high water-absorbing property, such as pulverized wood pulp such as mechanical pulp, chemical pulp and semi-chemical pulp, pulverized chemical fiber, pulverized waste paper pulp, wood It can be set as powder, paper powder, diaper waste pulverized material, crushed paper such as titanium paper or punch waste, or a mixture of two or more thereof. These water-absorbing materials preferably have a particle size of 5 mm or less, preferably 3 mm or less.

  In the present invention, the paper powder of the water-absorbing material powder means powdered paper or powdered paper containing a water-absorbing resin. For example, paper powder generated during bookbinding, paper powder generated during paper non-woven fabric manufacture In addition, there are paper powders generated in the papermaking process, and other water absorbent material powders are pulverized products of one or more sanitary products such as paper diapers, sanitary napkins, milk pads, urine pads or sweat pads, Waste diaper waste, sanitary napkin waste, dairy pad waste, urine pad waste, sweat pad and other sanitary waste pulverized products, dust collection loss and trim loss at sanitary ware manufacturing plants such as paper diapers Sanitary material waste materials and paper powder containing highly water-absorbing resin that scatters when manufacturing sanitary products.

  When the pulverized product of wood powder and punch waste is added to the wood pulp, the amount of the pulverized product of wood powder and punch waste is 3 to 20% by weight, preferably 3 to 10% by weight of the wood pulp.

Can do.

  Moreover, in this invention, paper diaper waste materials, such as a paper diaper with a poor test | inspection and a paper diaper cutting waste, can be used for a water absorbing mixed layer part. The disposable diaper material contains cotton pulp, that is, paper dust and a highly water-absorbing resin component, for example, about 70% by weight, so that it has a considerable water-absorbing and water-holding property. Since the material is used in an amount of 5 to 15% by weight, the water absorption and water retention are reduced accordingly. However, it has been found that plastic materials and rubber materials can be used in the water-absorbing layer portion of sanitary sheets because pulverized products pulverized to a particle size of 5 mm or less, preferably 3 mm or less, have water retention. It was. In addition, the blending of such plastic materials and rubber materials into the water-absorbing mixed layer portion, when incinerated, has a large calorific value of the plastic materials and rubber materials, and helps burn, so in a wet state after use. It has also been found that it becomes possible to burn sanitary sheets. In particular, in the case of a sanitary sheet in which a pulverized material of waste paper diapers is blended in the water-absorbing mixed layer portion, it has been found that the sanitary sheet has a calorific value capable of burning even in a wet state after use.

  In the present invention, when using sanitary sheets, the sanitary sheets have a water content of 10% by weight or less, preferably in order to avoid the growth of bacteria such as green bacterium, streptococci, Staphylococcus aureus, Legionella, and Potulinus. At least one thin paper used for the water-absorbing paper which is dried to 7% by weight or less, more preferably 5% by weight or less and which constitutes the water-absorbing first paper layer part in contact with the lower surface of the nonwoven fabric layer part of the sanitary sheet Includes at least one dry extract of tea extraction residual waste liquid, or one or more tea cake leachate, or a mixture of two or more dry products.

  Thus, when using sanitary sheets, the thin paper used for water-absorbing paper or the first water-absorbing first to avoid the growth of bacteria such as green bacterium, streptococcus, Staphylococcus aureus, Legionella bacterium and Potulinus. In order to include in the paper layer part the dried product of one or more tea extraction residual waste liquids, or the dried product of one or more tea liquors, or a mixture of these two or more dried products, as in the case of sanitary paper, One or more types of tea extraction residual waste liquid or one or more types of tea brewing liquor or a mixture of two or more types of these liquids are dripped or diluted or converted into ink and attached to thin paper by printing, coating, or dipping. Then, it is performed by drying.

  In this case, the one or more kinds of extracted residual waste liquid and / or one or more kinds of tea liquor leachate can be attached to one or more thin paper sheets constituting the first paper layer part that are not integrated with the water absorbing layer part. However, the tea extraction residual waste liquid and / or the tea liquor leachate is added to the water-absorbing first paper layer part formed of water-absorbing paper composed of one or more thin paper sheets integrated with the water-absorbing layer part. Alternatively, it can be diluted or converted into ink and attached by printing, coating or dipping. In this case, the tea extraction residual waste liquid and / or tea husk leachate, that is, the tea extraction residual waste liquid or tea brew liquor or a mixture thereof permeates the first paper layer portion and at least part of the water absorbing layer portion. It may be contained in.

In the present invention, the water-absorbing first paper layer portion is formed from at least one thin paper, but one or more tea extraction residual waste liquids and / or one type of thin paper forming the water-absorbing first paper layer portion is used. The amount of the tea brewing liquid applied is, for example, 2 to 3 liters, preferably 2.3 to 2.8 liters of tea extraction residual waste liquid or tea brewing liquid per 500 m ^{2 of} thin paper.
In the present invention, for example, the residual tea waste liquor and / or the tea liquor leaching solution is produced by leaching with room temperature water or heated water having a temperature exceeding room temperature, 10 times or less, preferably 5 times or less of the tea husk. It is preferable that the amount of zinc which is one of the tea components in 100 g of the leachate is 0.9 μg or more, preferably 5 μg or more.

  The tea extraction residual waste liquid or tea husk used in the present invention is discharged along with the tea husk or tea husk when producing canned tea or instant tea. The tea extraction residual waste liquid is contained in the tea husk after tea extraction, and is partially separated in the process of filtering the tea husk discharged from the tea husk or extracted from the tea husk after the tea extraction. In the present invention, the tea husk contains the tea extraction residual waste liquid as described above, and contains a tea extraction residual waste liquid having a water content of 70% by weight or more, and preferably a water content of 80% by weight or more. When leaching with room temperature water having a weight of not more than 10 times, preferably not more than 5 times with respect to tea husk or with heated water having a temperature not less than room temperature, the resulting leachate contains a tea extraction residual waste solution and the tea extraction. Occasionally, the components remaining in the unextracted rice cake are dissolved and contained. In particular, for example, tea leaves of green tea, oolong tea or black tea are leached with heated water at a temperature higher than the normal extraction temperature of tea, for example, at a temperature of 80 ° C. or higher, preferably 90 ° C. or higher, more preferably boiling water. Thus, it is preferable to extract undissolved components as much as possible.

In the present invention, the tea extraction residual waste liquid and / or the tea liquor leachate can be blended with the printing ink composition or further blended with an appropriate colorant to form a color ink. When the printing ink is used in this way, a desired pattern and characters can be printed over the entire surface of the water-absorbent first paper layer. For example, a decorative nonwoven fabric and a commercial advertising pattern and characters can be printed with a water-permeable nonwoven fabric. It can print on a layer part or a water-absorbent paper layer part.
After this application, the thin paper, water-absorbing paper or first paper layer part to which one or more tea extraction residual waste liquid and / or one or more tea shell leaching liquids are adhered is then dried, whereby one or more tea extractions are performed. A thin paper or a first paper layer portion to which a dried product of residual waste liquid and / or a dried product of one or more tea leaves is obtained is obtained.

The concentration of the one or more tea extraction residual waste liquids and / or one or more tea shell extract residual liquids impregnated in the thin paper, absorbent paper, or first paper layer is the volume of the diluent used relative to the volume of the extraction residual waste liquid, or It can be adjusted by changing the capacity of brewing water or heating water with respect to the unit weight of the tea husk. Since the tea husk is easily leached, it can be leached in a relatively short time, and the leaching time is preferably within 2 hours, particularly within 1 hour because the extraction time can be reduced.
In the present invention, the water-absorbing mixed layer portion of the sanitary sheet is made of paper powder or cotton pulp waste material containing a highly water-absorbing resin in order to keep the water absorption of the paper diaper, sanitary napkin or animal sheet. used. The amount of the superabsorbent resin used in this case is 5 to 15% by weight, preferably 7 to 10% by weight based on the total amount in the case of sanitary napkins and animal sheets, and the total amount in the case of disposable diapers.

Therefore, the upper water-absorbing paper 5 of the water-absorbing upper paper layer portion 5 is wound around the upper water-absorbing paper roll 20 and is drawn out by the upper water-absorbing paper feeding roller 21 provided below the upper water-absorbing paper. It is placed on the water absorbent layer portion 34 to form the water absorbent upper paper layer portion 5. The water-absorbing third paper layer portion 33 and the second paper layer portion 3 on which the upper water-absorbing paper 5 is placed are sent to the embossing machine 22 to form embossing.

  The lower water-absorbing layer portion 32 is formed between the water-absorbing second paper layer portion 3 and the water-absorbing third paper layer portion 33 by being embossed. An upper water-absorbing layer portion 34 is formed between the third paper layer portions 33, and these are formed integrally with the absorbent first to third paper layer portions 3, 5 and 33. Thus, the upper water-absorbing layer part 34 and the second water-absorbing layer part 32 formed integrally with the paper layer part are sent to the mat cutter 23 and cut into a length of 450 mm. Next, the upper water-absorbing layer portion 34 and the second water-absorbing layer portion 32 that are formed integrally with the paper layer portion are formed from the bottom at the bottom, and the polyethylene film 2 for the back film wound around the roll 24 is 24, is placed on the polyethylene film 2, and then sent to a location 25 where a nonwoven fabric made of polypropylene resin fiber is covered.

  On the other hand, the polypropylene resin fiber non-woven fabric forming the water-permeable non-woven fabric layer portion 6 is drawn from a roll 26 around which the non-woven fabric is wound. In the nonwoven fabric made of polypropylene resin fiber drawn out from the roll 26, the hot melt adhesive is sprayed from the sprayer 27 to the both end portions 36 of the bonded portion, and the first paper layer portion 5 on the upper water-absorbing layer portion. It is put on. The integrally formed paper layer portion and water-absorbing layer portion on which the polypropylene nonwoven fabric layer portion 6 is placed are sent to the side sealing machine 28, and both side portions are pressure-bonded and bonded by a hot melt adhesive. . The paper layer part and the water-absorbing layer part, which are integrally formed on both side end parts 36, are sent to the end seal machine 29 and both end parts in the longitudinal direction are adhered to each other and sent to the product cutter 30, and have predetermined dimensions. Cut into products and sent as products. The water-absorbing layer portion 4 bonded to both sides is sent to the end seal machine 29 and bonded at both ends in the longitudinal direction, sent to the product cutter 30, cut into a predetermined dimension by the product cutter 30, and product hygiene. The sheet is sent as a sheet 1, moved on the conveyance path 31, folded by a folding machine, packaged by a packaging machine (none of which are shown), and shipped.

In this example, the example of the first paper layer portion formed by the thin paper containing the dried product of the tea liquor was shown, but the water-absorbent first formed by the thin paper containing the dried product of the tea extraction residual waste liquid was shown. One paper layer part can be used, and it contains a dry mixture of a mixture of tea leaves such as green tea, oolong tea and / or black tea, mixed with a tea residual residue such as green tea, oolong tea and / or black tea. A water-absorbent first paper layer formed by thin paper can be used.
In this example, the upper water-absorbing layer portion and the lower water-absorbing layer portion are both mixed with disposable diaper waste powder and a superabsorbent resin. In order to increase the absorption rate, the upper water-absorbing layer part can be made only of diaper waste material ground powder. Moreover, the composition of the upper water-absorbing layer part and the lower water-absorbing layer part can be changed according to the purpose.

  In the present invention, the tea extraction residual waste liquid and / or the tea liquor leachate is used to suppress the growth of bacteria during the use of sanitary sheets, so a large amount of tea shell and tea extraction residual waste liquid will be used. Conventionally, waste liquid that has been treated by activated sludge treatment or the like can be used effectively, and waste and waste liquid treatment steps in the production of canned tea or instant tea can be omitted, and for example, disposable diaper waste can be used effectively.
