Abstract

A humidification filter, in one aspect, includes at least one of natural fiber and regenerated fiber mixed with a hydrophobic synthetic fiber.

First claim

What is claimed is:

1. An apparatus comprising:
a hydrophobic synthetic fiber; and
at least one of a natural fiber and a regenerated fiber mixed with the hydrophobic synthetic fiber,
wherein the apparatus is a humidification filter.

2. The apparatus as claimed in claim 1 , wherein the hydrophobic synthetic fiber is unprocessed by hydrophilic coating treatment on the hydrophobic synthetic fiber.

3. The apparatus as claimed in claim 1 , wherein the at least one of the natural fiber and the regenerated fiber is at least a natural fiber that is one of a hemp fiber, a cotton fiber, and a bamboo fiber.

4. The apparatus as claimed in claim 1 , wherein the at least one of the natural fiber and the regenerated fiber is at least a regenerated fiber that is viscose rayon.

5. The apparatus as claimed in claim 1 , wherein the hydrophobic synthetic fiber is any one of polypropylene (PP) and polyethylene terephthalate (PET).

6. The apparatus as claimed in claim 1 , wherein the apparatus is a humidification filter having a woven form in which the at least one of the natural fiber and the regenerated fiber is woven with the hydrophobic synthetic fiber.

7. The apparatus as claimed in claim 6 , wherein the woven form of the apparatus is a porous mesh.

8. The apparatus as claimed in claim 1 , wherein the apparatus is a humidification filter having a non-woven form in which the at least one of the natural fiber and the regenerated fiber is mixed with the hydrophobic synthetic fiber by adhesion or entanglement.

9. The apparatus as claimed in claim 8 , wherein the apparatus is a humidification filter having the non-woven form with a density of 80 to 110 g/m 2 .

10. The apparatus as claimed in claim 1 , wherein the apparatus is a humidification filter having a plurality of folds.

11. The apparatus as claimed in claim 1 , wherein the natural fiber or the regenerated fiber consist of a single strand.

12. The apparatus as claimed in claim 11 , wherein the hydrophobic synthetic fiber is included in the apparatus in a mixing rate of 70 to 90%.

13. The apparatus as claimed in claim 1 , wherein the natural fiber or the regenerated fiber are made by twisting a plurality of strands.

14. The apparatus as claimed in claim 13 , wherein the hydrophobic synthetic fiber is included in the apparatus in a mixing rate of 50 to 90%.

15. A humidification filter comprising:
a natural or regenerated fiber to absorb water provided to the humidification filter and desorb the water by evaporation; and
a synthetic fiber having a strength greater than that of the natural or regenerated fiber, mixed with the natural or regenerated fiber to provide strength to the humidification filter, and being substantially free of vaporizable hydrophilic chemical substances.

16. The humidification filter according to claim 15 , wherein the natural or regenerated fiber is any one of a hemp fiber, a cotton fiber, a bamboo fiber, and a regenerated fiber having a cellulose molecular structure.

17. The humidification filter according to claim 15 , wherein the synthetic fiber has a mixing rate of 50 to 90% in the humidification filter.

18. A vaporizing humidifier comprising:
the humidification filter according to claim 15 ; and
a water tank to supply the water to the natural or regenerated fiber.

19. The vaporizing humidifier of claim 18 , further comprising an air blowing fan to cause the natural or regenerated fiber to desorb the water by evaporation.

20. A vaporizing humidifier comprising:
a humidification filter including a hydrophobic synthetic fiber and at least one of a natural fiber and a regenerated fiber mixed with the hydrophobic synthetic fiber.

21. The apparatus as claimed in claim 1 , wherein the hydrophobic synthetic fiber is substantially free of vaporizable hydrophilic chemical substances.
