| titleOfInvention | Air filter and its manufacturing method |
| abstract | PROBLEM TO BE SOLVED: To purify air containing oil mist and dust and suppress clogging. SOLUTION: An air filter containing a non-woven fabric in which a large number of pores penetrating between one surface into which air containing oil mist and dust flows in and another surface in which air flows out facing the one surface is formed between fibers. be. Repellent containing metal oxide particles (B) having an average particle diameter of 2 nm to 90 nm and silica sol gel (C) in which a fluorine-based functional group component (A) containing a perfluoroether structure of the formula (1) is bonded to the fiber surface of a non-woven fabric. A water-repellent film is formed. The compound (A) is contained in a proportion of 1 to 30% by mass when the film is 100% by mass, and the compound (A) and the particles (B) are 5 to 80% by mass when the film is 100% by mass in total. The mass ratio (A / B) is in the range of 0.05 to 0.80, and the filter air permeability is 1 to 30 ml / cm 2 / sec. [Selection diagram] Fig. 1 |
