A recently filed patent (Publication Number: US20230191294A1) describes a filter medium with specific characteristics and a method for producing it. The filter medium consists of a first layer, a second layer with pores ranging from 4-13 µm in diameter, and optionally, a third layer. The second layer can be a dry-laid nonwoven material, a spunbond layer, a meltblown layer, or a combination of a spunbond layer and a meltblown layer. The first layer is made of cellulose, and the second layer can be densified and composed of polyester fibers or a densified meltblown layer.
The filter medium exhibits certain properties, such as increasing air permeability from the first layer to the second layer, and optionally, from the second layer to the third layer. Additionally, the basis weight of the filter medium can increase from the second layer to the first layer, and optionally, from the third layer to the first layer.
The patent also includes a method for using the filter medium, which involves filtering a liquid with the filter medium. During the filtering process, the flow direction of the liquid is from the second layer to the first layer, and optionally, from the third layer to the first layer. The liquid being filtered can be fuel, oil, or water.
Furthermore, the patent describes a method for producing the filter medium. This method involves providing the first layer, the second layer, and optionally, the third layer. The second layer is then densified, and finally, the first layer, second layer, and optionally, the third layer are joined together.
Overall, this patent presents a filter medium with specific layer compositions and characteristics, along with methods for using and producing it. The filter medium's design allows for effective filtration of liquids, with the flow direction and layer properties optimized for different applications.
