Further, in the present invention, waste paper diapers such as disposable diapers and paper diaper cutting chips which are not inspected can be used for the water-absorbing mixed layer portion. Disposable diaper waste material has considerable water absorption and water retention because it contains, for example, about 70% by weight of cottony pulp, that is, paper powder and a highly water-absorbing resin component. Since the material is used in an amount of about 5 to 15% by weight, the water absorption and the water retention are reduced accordingly. However, plastic materials and rubber materials are found to be able to be used for the water-absorbing layer of sanitary sheets because the ground material having a particle size of 5 mm or less, and preferably a particle size of 3 mm or less, has water retention. Was. In addition, when such a plastic material or rubber material is mixed into the water-absorbing mixed layer portion, the amount of heat generated by the plastic material and the rubber material is large when incinerated.
It has been found that the sanitary sheets can be burned even in a wet state after use because they help combustion.
In particular, in the case of a sanitary sheet in which a pulverized waste paper diaper was mixed into the water-absorbing mixed layer portion, it was found that the sanitary sheet had a calorific value enough to burn the sanitary sheet even in a wet state after use.
