Especially in the case of air filters and liquid filters, the filtration performance is good. In addition, it is required that the initial filtration performance can be maintained, that the shape stability is good and the elongation is small. For example, when used for press rolls when used for squeezing water, if there is no core material as a filter material, repeated compression will result in a large decrease in felt thickness and sufficient water squeezing and durability. .
