2. Description of the Related Art In general, sanitary sheets include auxiliary sheets for bedding, disposable diapers, sanitary napkins, breast pads, sweat pads, and the like.
Used in sanitary sheets such as incontinence pads and pet sheets. For example, auxiliary sheets for bedding are used to lay on a bed or a futon to maintain the durability of the bed or the futon and to keep the bed or the futon clean. During bedtime, moisture other than sweat is constantly excreted outside from human skin, and these moistures are absorbed by the bed or the bedclothes. It is required to have appropriate hygroscopicity.

Since the disposable diaper contains, for example, about 70% by weight of flocculent pulp, that is, paper powder and superabsorbent resin,
Although it has considerable water absorption and water retention, the plastic material and the rubber material are used in an amount of 5 to 15% by weight for the water-impermeable membrane or the like. However, plastic materials and rubber materials can be used in the water-absorbing mixed layer portion of sanitary sheets because the pulverized material, which is pulverized to a particle size of 5 mm or less, preferably 3 mm or less, exhibits water retention. Was. In addition, when the plastic material and rubber material are mixed into the water-absorbing mixed layer, since the plastic material and rubber material generate a large amount of heat when incinerated, the pulverized waste paper diapers are mixed into the water-absorbing mixed layer. In the case of the sanitary sheet that was used, it was found that the sanitary sheet had a calorific value enough to burn the sanitary sheet even in a wet state after use.
