Water-decomposable cleaning product and production method thereof

1. A water-decomposable toilet cleaning brush configured to be coupled to a holder having a handle which water-decomposable toilet cleaning brush comprises:

a cleaning part, at least a part of the cleaning part including a string formed by twining a water-decomposable fiber-interlacing nonwoven fabric; and

a holding part comprising water-decomposable fiber-interlacing nonwoven fabrics that are adhered with a water-soluble adhesive,

wherein the fiber-interlacing nonwoven fabric of each of the cleaning part and the holding part is decomposable in water in no greater than 700 seconds,

wherein the water-decomposable cleaning brush is sufficiently small to allow the water-decomposable cleaning brush to be discarded by flushing the water-decomposable cleaning brush down a standard toilet after water decomposition, and

wherein the string formed by twining the water-decomposable fiber-interlaced nonwoven fabric remains sufficiently stiff after bean wetted b water and before decomposition to perform a scrubbing action.

2. The water-decomposable toilet cleaning brush product as claimed in claim 1 , wherein the fiber-interlacing nonwoven fabric includes fibers each having a length of 20 mm or less.

3. The water-decomposable toilet cleaning brush as claimed in claim 1 , wherein the fiber-interlacing nonwoven fabric includes:

natural fibers, and

interlaceable fibers each having a length of 20 mm or less.

4. The water-decomposable toilet cleaning brush as claimed in claim 3 , wherein the natural fibers are pulp fibers, and

the fiber-interlacing nonwoven fabric includes:

between 10% by mass and 90% by mass of the pulp fibers and between 10% by mass and 90% by mass of the interlaceable fibers.

5. The water-decomposable toilet cleaning brush as claimed in claim 3 , wherein the interlaceable fibers are rayon fibers.

6. The water-decomposable toilet cleaning brush product as claimed in claim 1 , wherein the string includes:

the fiber-interlacing nonwoven fabric and

a water-decomposable paper including cellulose fibers.

7. The water-decomposable toilet cleaning brush product as claimed in claim 1 , wherein the string is compressed.

8. The water-decomposable toilet cleaning brush as claimed in claim 1 ,

wherein the cleaning part includes a brush part formed by the fiber-interlacing nonwoven fabric in a strip form.

9. The water-decomposable toilet cleaning brush as claimed in claim 1 , wherein

the cleaning part includes the fiber-interlacing nonwoven fabric which is subjected to bundling up to thereafter form a part of the water-decomposable cleaning product.

10. A method for manufacturing a water-decomposable toilet cleaning brush, which method comprises:

forming each of a plurality of strings by twining a water-decomposable fiber-interlacing nonwoven fabric; and

arranging the plurality of strings in a cleaning part and adhering at least a part of the strings to each other with a water soluble adhesive so as to form a holding part,

wherein the fiber-interlacing nonwoven fabric is decomposable in water in no greater than 700 seconds,

wherein the water-decomposable cleaning brush is sufficiently small to allow the water-decomposable cleaning brush to be discarded by flushing the water-decomposable cleaning brush down a standard toilet after water decomposition, and

wherein the plurality of strings formed by twining the water-decomposable fiber-interlaced nonwoven fabric remain sufficiently stiff after being wetted by water and before decomposition to perform a scrubbing action.

11. The method for manufacturing of a water-decomposable toilet cleaning brush as claimed in claim 10 , wherein

the fiber-interlacing nonwoven fabric includes:

between 10% by mass and 90% by mass of pulp fibers, and between 10% by mass and 90% by mass of interlaceable fibers.

12. A water-decomposable toilet cleaning brush configured to be coupled to a holder having a handle which water-decomposable toilet cleaning brush comprises:

a cleaning part, at least a part of the cleaning part including a string formed by twining a water-decomposable fiber-interlacing nonwoven fabric; and

a holding part comprising water-decomposable fiber-interlacing nonwoven fabrics, the water-decomposable fiber-interlacing nonwoven fabrics being compressed in the holding part, wherein the fiber-interlacing nonwoven fabrics of each of the cleaning part and the holding part is decomposable in water in no greater than 700 seconds,

wherein the water-decomposable cleaning brush is sufficiently small to allow the water-decomposable cleaning brush to be discarded by flushing the water-decomposable cleaning brush down a standard toilet after water decomposition, and

wherein the string formed by twining the water-decomposable fiber-interlaced nonwoven fabric remains sufficiently stiff after bean wetted by water and before decomposition to perform a scrubbing action.
