DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to, for example, the paper diaper waste relates to hygiene sheets using waste material such as sanitary napkins waste, in particular, bedding sheets, diaper, disposable diapers and animals for disposable diapers, sanitary napkins, The present invention relates to a sanitary sheet which can be used for an animal sanitary napkin, a milk pad, a sweat pad, an incontinence pad, and an animal sheet. The present invention also prolonged relates sanitary sheets disposable capable of holding hygiene use, in particular, for sleeping device sheets, diaper, disposable diapers, animal diapers, sanitary napkins, veterinary sanitary napkin The present invention relates to a disposable sanitary sheet which can be used for milk pads, sweat pads, incontinence pads and animal sheets.

[0002]

2. Description of the Related Art Generally, hygienic sheets include bedding sheets, disposable diapers, sanitary napkins, milk pads, sweat pads, and the like.
It is used for incontinence pads, diapers and pet sheets. For example, bedding sheets are laid on a bed or a mattress to maintain the durability of the bed or the futon and to keep the bed or the futon clean. Even at bedtime,
From the human skin, water other than sweat is constantly excreted outside, and these waters are absorbed into the bed or sleeping clothes.For example, bedding sheets have heat retention and moderate moisture absorption. Is required.

[0003] In addition, since bedding sheets and bedding are formed of fibers having high hygroscopicity and water absorbency, keratinized stratum corneum that has fallen off the skin surface and dust adhering to the skin are affected by sebum and sweat of the skin. Debris and the like tend to adhere and become easily contaminated, causing the growth of pathogenic bacteria. This is a problem particularly in the case of pressure ulcers and the like. Therefore, in order to keep the cleanliness of the bedding sheets and bedding, cotton, etc., which is resistant to washing, is frequently used as a material so that it can be frequently replaced and used repeatedly so as to always maintain the cleanliness.

[0004]

However, in the case of bedding sheets made of cotton or the like, they are washed every time they are replaced.
Since it is relatively bulky, the degree of dirt is different, and the degree to which it can be cleaned by washing is also different, it is difficult to clean as desired even with an automatic washing machine,
Also, doing so requires a lot of trouble. Therefore, disposable bedding sheets provided with a water-absorbing layer in which a pulverized pulp contains a powdery superabsorbent resin are used. However, since crushed pulp is more difficult to obtain than before and is relatively expensive, disposable bedding sheets reduce the amount of pulp crushed and reduce the amount of pulp crushed. It is formed by supplementing the water absorbing ability with a highly water-absorbing resin. For this reason, the bedding sheets are formed to be relatively thin, have poor elasticity, and are relatively hard, which is a problem. Also, the calorific value of the superabsorbent resin added to supplement the pulp pulverized material is considerably lower than the calorific value of the reduced pulp pulverized material. Combustion cannot be maintained unless fuel is added, and incineration cannot be achieved unless heat is applied from the outside.

On the other hand, the amount of tea leaching tea husks discharged from the manufacturing industry of canned tea and packed tea, and tea husk residue liquid remaining on the tea husks and oozing out of the tea husks is enormous. ing. However, since tea husks contain a considerable amount of residual tea husks, even if they are effectively used for compost or the like, their treatment is difficult and problematic. In addition, since the residual tea liquor contains tannins, it cannot be discarded as it is. To discard it, it must be detoxified by an activated sludge method or the like, and the precipitate is exclusively used. It has to be incinerated. The present invention solves a problem that requires much labor when reusing a conventional bedding sheet or the like, and also treats a tea husk and a tea husk residual waste liquid generated in a process of manufacturing canned tea and packed tea. It is an object.

[0006]
