Abstract

PURPOSE:To reduce the filtration resistance and to filter off the suspended matter such as fatty acid esters by the hydrophobic-bond adsorption by mixing hydrophilic fiber, hydrophobic fiber and specified fine grains as a filter aid in a specified ratio. CONSTITUTION:From 10 to 75wt.% of >=1 kind of hydrophobic fiber among the polyolefin, polyester and acrylic fibers, 0-50wt.% of hydrophilic fiber such as natural cellulose and 25-90wt.% of fine grains such as diatomaceous earth as a filter aid are mixed, and the mixture is formed into a filter sheet. Since the sheet contains the fibers having hydrophobic-bond adsorptivity, the suspended matter consisting of fatty acid esters can be removed by the sheet. In addition, hydrophilicity is imparted to the sheet itself by the contained hydrophilic fiber, the filtration resistance of the sheet is effectively reduced.

As mentioned above, Examples 1 to 6 all had high removal rates, and all except Example 4 had long filtration lives of 50 hours or more. With the conventional technology, the removal rate is insufficient as in Comparative Example 1, and if finer particles are used to increase the removal rate as in Comparative Example 2, the removal rate can be improved to some extent, but the removal rate is high and the filtration resistance is high. Filtration life is shortened to 8 hours. In addition, in Example 4 where the blending ratio of fine particles was 80%, the filtration life was slightly shorter at 25 hours compared to other examples, but the removal rate was much better than Comparative Example 1, and the filtration life was 25 hours. The length was also considerably longer than that of Comparative Example-2.
