Abstract
Provided is a filter structure for filtering passing gas by being adhered to an object. The filter structure includes: a filter layer including a sheet-shaped member having air permeability; and an adhesive layer that is formed on at least a part of one surface of the filter layer and is configured to be adhered to the object. The adhesive layer is formed of an acrylic hot-melt adhesive, has a ratio K1/K2 of a maximum peeling load K1 at 25° C. to a maximum peeling load K2 at 5° C. in a range of 1 to 6, and the filter structure does not separate from the object when adhered to the object under a temperature condition of 25° C. or 5° C.
Claims5
A filter structure (F) configured to filter passing gas by being adhered to an object, the filter structure comprising:
- a filter layer (S) including a sheet-shaped member having air permeability;
- and
- an adhesive layer (N) that is formed on at least a part of one surface of the filter layer and is configured to be adhered to the object, wherein
- the adhesive layer is formed of an acrylic hot-melt adhesive (M), has a ratio K1/K2 of a maximum peeling load K1 at 25° C. to a maximum peeling load K2 at 5° C. when adhered to the object in a range of 1 to 6, and the filter structure does not separate from the object when adhered to the object under a temperature condition of 25° C. or 5° C.
