2. Description of the Related Art In general, nonwoven fabrics are used as sanitary materials in bedding sheets, disposable diapers, sanitary napkins, breast pads, sweat pads, incontinence pads, diapers and pet sheets, and also as medical materials. It is used for masks, gowns, caps, gauze, bandages, eye patches, sterile packaging materials, etc. Hygiene articles and medical materials are required to have flexibility, water absorption and strength, and to be clean, and even in the case of nonwoven fabrics used for absorbent articles for hygiene articles,
For example, in the case of sheets for bedding, they are laid on a bed or mattress to maintain the durability of the bed or mattress and to keep the bed or mattress clean. It is required to have flexibility, water absorption and strength, and to be clean.

For example, even at bedtime, from human skin,
In addition to sweat, water is constantly excreted outside, and these waters are absorbed by the bed or bedclothes.For example, hygiene products used for bedding sheets have more heat retention and moderate hygroscopicity. It is required to prepare. Also, bedding sheets and bedding are made of highly hygroscopic and highly water-absorbing fibers, so that keratinized stratum corneum that has fallen off the skin surface and dust that has adhered to the skin may have dirt such as sebum or sweat on the skin. It adheres and is easily contaminated, causing the growth of pathogenic bacteria, and is a problem particularly in the case of pressure ulcers and the like. Therefore, in order to keep the cleanliness of the conventional bedding sheets and bedding, cotton or the like that is resistant to washing is used as a material so that it can be frequently replaced and used repeatedly.

[0004]

Accordingly, a disposable-type bedding sheet and an absorbent material used for the bedding are designed so that they can be kept clean for a long time even when used. Applicant has paid attention to the fact that the extract of tea husks, which is the extraction residue of coffee liquor provided for beverages, has a sterilizing effect, and has developed a sanitary ware containing a dried product of the extraction residue of roasted coffee beans. Have been proposed (JP-A-10-337238, JP-A-2000-60908).
Gazette and JP-A-2000-192396). However, the present inventor has found that the dried product of the concentrated liquid of the coffee extract of the roasted coffee beans or the dried product of the concentrated solution of the extracted liquid further extracted from the extraction residue of the coffee liquid of the roasted coffee beans is For Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus and Legionella bacteria, it has a growth inhibitory effect even after 72 hours of inoculation, but 72 hours after inoculation against Escherichia coli and Salmonella bacteria However, it was found that the growth inhibitory effect was almost non-existent or low. In addition, the present inventor has proposed that green tea, tea extracted from tea leaves such as oolong tea or black tea, particularly dried product of green tea concentrate or tea husk, especially dried product of tea husk extract concentrated extract of green tea husk, , Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella,
For streptococci and bacteria of the genus Legionella, 7
It was found that even after 2 hours, it had a growth inhibitory effect. In addition, the dried product of the concentrated tea husk extract extracted from the tea husks of black tea is 72% after inoculation against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus and Legionella bacteria.
It has been found that even after a lapse of time, it has a growth inhibitory effect.

[0005] On the other hand, the coffee residue extracted from the canned coffee liquor and the packed liquor extracted from the coffee liquor manufacturing industry remains in the extracted residue of the roasted coffee beans and the extracted residue of the roasted coffee beans. There is an enormous amount of residual extract liquid, tea husks discharged from the manufacturing industry of canned tea, and tea husk residual effluents remaining in the tea husks and exuding from the tea husks. Further, since tea leaves contain an extraction residual liquid containing a considerable amount of tannins, it is difficult to treat tannins and the like even when used for compost and the like.
In addition, since the residual waste liquid of the extraction residue of roasted coffee beans also contains a considerable amount of tannins, it cannot be disposed of as it is. There must be. Despite the huge amount of the sediment generated by the activated sludge method, the sediment is scarcely used and used exclusively by incineration, which is a problem. The present invention solves the problems related to bacteria of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella, Streptococcus and Legionella with respect to the nonwoven fabric, and a process for producing canned coffee liquid and packed coffee liquid. The purpose of this invention is to treat the coffee liquor of the extraction residue and residual waste liquid of roasted coffee beans and the tea husk and the residual waste liquor of tea husk generated in the above.
