Problems solved by technology

However, when the rigidity of the filter medium is too high, the creases will gradually deform into arcs over time after pleat processing, and thus the structural resistance may increase during use.

Embodiment Construction

[0041] Hereinafter, the pleating processing method of the filter medium for air filters, the filter medium for air filters, and the air filter for air cleaners of this invention are demonstrated.

[0042] The method for processing a filter medium for an air filter according to the present embodiment includes a step of subjecting a filter medium for an air filter (hereinafter, also referred to as a filter medium) to a pleating process, wherein the filter medium for an air filter has a melt-blown non-woven fabric. The collection layer composed of woven cloth has the stiffness and softness (hereinafter, stiffness and softness) of the filter medium for air filters measured by the Gurley method described in JIS-L1085-6.10.3 exceeding 6 mN, and is implemented electret treatment. In the step of implementing this pleating process, the filter medium is subjected to compression heat treatment under the conditions of more than 80° C. and 90° C. or lower and for 15 minutes to 30 minutes. ...

Abstract

The invention relates to a filter material and a drape processing method therefor as well as an air filter for an air purifier. The filter material which inhibits decrease of a capture performance and raise of structural resistance can be obtained. An embodiment of the invention refers to the drape processing method for the filter material for the air filter. The method is characterized by comprising the step of processing drapes of the filter material on the air filter, wherein the filter material for the air filter has a capture layer consisting of a melt-blown non-woven fabric; the soft rigidness of the filter for the air filter detected by Gurley method according to JIS-L1085-6.10.3 exceeds 6 mN and the stationary treatment is carried out on the filter material; in the step of processing the drapes, compression and heating treatment on the filter material for the air filter is carried out under the condition that the temperature is higher than 80 DEG C but lower than 90 DEG C and the time is 15-30 minutes.

Description

technical field [0001] The present invention relates to a method for pleating a filter medium for an air filter, a filter medium for an air filter, and an air purifier. Background technique [0002] When a filter medium for an air filter that is pleated in a zigzag shape is deformed by wind pressure during use, the pressure loss may increase. The reason for such an increase in pressure loss is an increase in structural resistance. Conventionally, in order to suppress such an increase in structural resistance, it is known that the stiffness and softness of the filter medium are adjusted to a predetermined range (for example, Patent Document 1). However, when the rigidity of the filter medium is too high, the crease is gradually deformed into a circular arc with the passage of time after the pleating process, which may result in an increase in structural resistance during use. Therefore, the effect of suppressing the rise in structural resistance obtained by adjusting the st...
