BACKGROUND OF THE INVENTION
The present invention, tissue paper, toilet paper, relates sanitary paper is a toilet paper or sanitary paper, in particular, bedding sheets, disposable diapers, animal diapers, sanitary napkins, veterinary sanitary napkins, dairy pads, perspiration pads and animals The present invention relates to a sanitary paper that is a tissue paper, a dust paper, a toilet paper, or a sanitary paper that can be used for an absorbent paper layer of a sanitary sheet such as a sheet.
[0002]
[Prior art]
In general, sheets are used in bedding sheets, paper diapers, sanitary napkins, milk pads, sweat pads, pet sheets, and the like. For example, bedding sheets are used to lay on a bed or mattress to maintain the durability of the bed or futon and keep the bed or futon clean.
While sleeping, moisture is continuously excreted from the human skin in addition to sweat, and these moisture is absorbed by the bed and nightclothes. It is required to have a hygroscopic property.
[0003]
In addition, bedding sheets and bedding are made of highly hygroscopic and water-absorbent fibers, so the keratinized stratum corneum that has fallen from the skin surface and the dirt that adheres to the skin can be contaminated with sebum or sweat from the skin. It adheres and is easily contaminated, causing pathogenic bacteria to grow, which is a problem particularly in the case of pressure sores.
Therefore, for bedding sheets and bedding, in order to always keep cleanliness, cotton that is resistant to washing is used as a material so that it can be frequently replaced and used repeatedly so that it can always be kept clean.
[0004]
[Problems to be solved by the invention]
However, if the bedding sheets and bedding cotton made such, each time replacing, but are laundered, relatively bulky tension, also different degrees of soiling, and because also different enough to be cleaned by washing, automatic washing Even if it depends on the machine, it is difficult to clean as desired, and it takes a lot of trouble to do so.
Therefore, disposable bedding sheets are provided in which a pulp layer is provided with a water-absorbing layer containing a highly water-absorbent resin. However, since pulp pulverized products are more difficult to obtain and relatively expensive than before, the amount of pulp pulverized products used is reduced, and the water absorption capacity reduced by the saving of pulp pulverized products is compensated with a highly water-absorbent resin. Therefore, it is formed into a relatively thin sheet, has a low elasticity, and has a problem of becoming a relatively stiff sheet. In addition, since the heat generation amount of the superabsorbent resin is considerably lower than the heat generation amount of the pulverized pulp, in the case of wet sheets, combustion cannot be maintained unless fuel is added, and heat must be applied from the outside. If it is incinerated, it is a problem.
[0005]
On the other hand, the residue of coffee liquid extraction from roasted coffee beans discharged from canned coffee and instant coffee manufacturing industry is enormous. However, the coffee extraction residue contains oil and fat, and also contains a considerable amount of residual liquid, so that it is difficult to use. For example, the residual liquid is treated by the activated sludge method and is entirely incinerated. Yes.
Further, paper sanitary goods such as paper diapers and paper sanitary napkins generate cutting waste and defective products, and their processing is a problem.
An object of the present invention is to solve the problems that require a lot of labor, such as washing, when replacing and reusing conventional sheets for bedding and the like, and an object of the present invention is to treat a coffee liquid extraction residue of roasted coffee beans.
[0006]
[Means for Solving the Problems]
The present inventor said that a re-extracted liquid from a coffee liquid extraction residue of roasted coffee beans and an extracted liquid from a tea husk of oolong tea, which are discharged in large quantities during the production of canned coffee and instant coffee, are Pseudomonas aeruginosa, Staphylococcus aureus Found that it inhibits the growth of Legionella and Streptococcus for more than 24 hours, and that the extract from green tea leaves over the growth of Staphylococcus aureus, Legionella and Streptococcus over 24 hours. Furthermore, the present inventor has discovered that the extract from black tea husk inhibits the growth of Staphylococcus aureus and Streptococcus over 24 hours. The re-extracted liquid from the residue, the extracted liquid from the tea leaves of oolong tea, the extracted liquid from the green tea leaves or the extracted liquid from the black tea leaves are all Pseudomonas aeruginosa, Staphylococcus aureus and Legionella. And the growth of Streptococcus discovered that inhibition for over 48 hours, leading to the present invention.
