Embodiment approach 1

[0042] figure 1 Is a schematic cross-sectional view showing an air filter filter according to Embodiment 1 of the present invention, figure 2 It is an enlarged view of the rosary fiber of the air filter element. Such as figure 1 with figure 2 As shown, the air filter element 11 includes: a thin fiber layer 12a composed of thin fibers 12; and a base material 13 for holding the thin fiber layer 12a. The thin fiber 12 has an average fiber diameter of 100 nm to 1000 nm, and is a bead-like fiber 16 composed of fibers 14 and beads 15. The thin fiber 12 and the base material 13 are joined by melting of the surface layer 15a of the bead.

[0043] Such as figure 2 As shown, the beads 15 of fine fibers 12 are spindle-shaped. By making the boundary 23 between the bead 15 and the fiber a curved line, the cut of the boundary between the fiber 14 and the bead 15 can be prevented. As a result, the filter performance of the air filter filter 11 can be stably obtained.

[0044] The thin fib...

Embodiment approach 2

[0056] In the second embodiment of the present invention, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted. Figure 5 It is a schematic cross-sectional view showing an air filter filter according to Embodiment 2 of the present invention.

[0057] Such as Figure 5 As shown, the air filter element 11a includes: a thin fiber layer 12a composed of thin fibers 12; a base material 13; and a protective layer 17 for protecting the thin fibers 12. The thin fibers 12 and the protective layer 17 are joined by melting of the surface layer 15a of the bead.

[0058] In such an air filter 11a, it is possible to prevent the damage of the fine fibers 12 caused by external contact. In addition, the beads 15 become flat, and the bonding area between the thin fibers 12 and the base 13 and the thin fibers 12 and the protective layer 17 increases. Therefore, compared with the case where the thin fiber 12 with...

[0062] Electrospinning a solution obtained by dissolving 20 wt% of PES (polyethersulphone) in DMAc (dimethylacetamide) to obtain figure 2 A rosary fiber 16 composed of fibers 14 and beads 15 is shown. At this time, cellophane with air permeability is pasted on the ground plate, so the cross section becomes figure 1 The structure shown.

[0063] The thin fiber surface of the air filter element 11 thus obtained was covered with a non-woven fabric sheet containing a low-melting resin material as a protective layer 17, with a thickness of about 800 cm 2 / min speed and 120°C temperature. Two types of samples with different non-woven fabric sheets were produced, and the pressure loss when air was passed through the air filter element 11a at a surface wind speed of 5.3 cm / sec is shown in Table 1. The pressure loss of the two types of samples increased slightly, but their The increase is within 5%, which is not a significant difference as the air filter 11a, and it was confirmed that h...

Abstract

A filter medium for air filters, said filter medium comprising a fine fiber layer configured from fine fibers having an average fiber diameter of 100 nm to 1000 nm and a base material for holding the fine fiber layer. The fine fibers are moniliform fibers consisting of fibers and beads and the fine fibers and the base material are welded by fusing the surface layer of the beads.

Description

Technical field [0001] The present invention relates to an air filter element, an air filter, an air purification device installed with the air filter, and an air purification device with a humidification function. Background technique [0002] Conventionally, an air filter filter assembled in an air conditioner or the like is laminated with a fine fiber layer and a base material (for example, refer to Patent Document 1). Below, refer to Figure 21 The air filter filter will be described. [0003] Figure 21 It is a schematic cross-sectional view of a conventional air filter filter. Such as Figure 21 As shown, the air filter 101 is sequentially provided with a fine fiber layer 102 having an average fiber diameter of 0.05 μm to 1 μm and a base material layer 103 in the dust load direction, that is, the air inflow direction. The thin fiber layer 102 and the base material layer 103 are fixed by bonding by the fusion and solidification of fibers or by bonding by a binder component adde...
