Air filter and method for producing same |
| abstract |
This air filter includes a nonwoven fabric having formed between fibers therein numerous pores that penetrate the fabric between one surface through which air containing oil mist and dust flows in and the other surface which is located on the opposite side of the one surface and from which said air flows out. On the surfaces of the fibers in the nonwoven fabric, a water-repellent and oil-repellent membrane is formed. The water-repellent and oil-repellent membrane contains a fluorine-including functional group component (A) and a silica sol-gel (C). The fluorine-including functional group component (A) is contained in a proportion of 0.01-10 mass% when the amount of the silica sol-gel (C) is defined as 100 mass% or in a proportion of 1-30 mass% when the amount of the water-repellent and oil-repellent membrane is defined as 100 mass%. The air permeability of the air filter is <sp />1-30 ml/cm 2 /sec. The fluorine-including functional group component (A) includes a perflluoroether structure represented by general formula (1).
