2. Description of the Related Art Generally, sanitary sheets are auxiliary sheets for bedding, disposable diapers, sanitary napkins, breast pads, sweat pads,
It is used for sanitary sheets such as incontinence pads and pet sheets. For example, bedding auxiliary sheets are laid on a bed or a futon to maintain durability of the bed or the futon and keep the bed or the futon clean. While sleeping, human skin constantly excretes moisture other than sweat, and these moisture is absorbed by the bedding and sleeping garments. It is required to have appropriate hygroscopicity.

[0004]

However, in the case of bedding auxiliary sheets made of cotton or the like, they are washed every time they are replaced, but they are relatively bulky and the degree of dirt is different, and they are cleaned by washing. Since the degree to which it can be done is also different, it is difficult to clean it as desired even with an automatic washing machine or the like, and it takes a lot of time and effort to do so.

On the other hand, there is a huge amount of coffee liquid extraction residue from roasted coffee beans discharged from canned coffee and instant coffee manufacturing industries. However, the coffee extraction residue is difficult to use because it contains fats and oils and a considerable amount of residual liquid, and a part of the residual liquid is extracted from the extraction residue after extraction of the extraction residue. It is collected for exudation and treated by the activated sludge method or the like, and the remaining extraction residue is entirely incinerated. Further, paper sanitary sheets such as a disposable diaper and a sanitary napkin have cutting scraps and defective inspection products, and their treatment is a problem.
The present invention has an object to solve a problem that a lot of labor is required when replacing a conventional bedding auxiliary sheet or the like, and to treat a coffee liquid extraction residue and exudate from the residue.

[0006]

The present inventor has found that a large amount is discharged during the production of canned coffee or instant coffee.

Can be used. Although the recovered superabsorbent resin has a poor water absorption capacity of 10 to 30 g / g against artificial urine, the hygroscopic sheets, for example, disposable diapers and animal sheets, absorb water at this level. It turned out that the effect was sufficient. The particle size of the super absorbent polymer used is preferably 50 to 500 μm.

Further, in the present invention, waste paper diapers such as paper diapers and paper diaper cutting scraps that have been inspected poorly are used in the water-absorbent mixed layer portion. The waste diaper material contains cotton-like pulp, that is, paper powder and a highly water-absorbent resin component, for example, in an amount of about 70% by weight, so that it has a considerable water-absorbing property and a water-retaining property. Material is 5 to 1
Since it is used in an amount of about 5% by weight, water absorption and water retention are reduced accordingly. However, it has been found that the plastic material and the rubber material can be used for the water-absorbent mixed layer portion of the sanitary sheet, because the pulverized product pulverized to a particle size of 5 mm or less, preferably 3 mm or less has water retention. .
Moreover, when the plastic material or rubber material is blended into the water-absorbent mixed layer, the crushed material of the waste paper diaper is blended into the water-absorbent mixed layer because the plastic material and the rubber material generate a large amount of heat when incinerated. For sanitary sheets,
It was found to have a calorific value capable of burning sanitary sheets even in a wet state after use.
