Abstract

PURPOSE: To reform the surface charge and improve adsorption efficiency of a filter aid of adsorptive cellulose by forming a complex of a high molecular electrolyte on the surface of cellulose fiber.
CONSTITUTION: Fibrillated cellulose fiber is dispersed in water or the like, and a cationic high molecular electrolyte, such as a condensate of polyamide epichlorohydrin is added to the resulting mass. The product thus obtained is heated. An amphoteric high molecular electrolyte, such as polyacrylamide is then added to the heated product, and the resulting mass is heated again. As a result, a complex of a high molecular electrolyte is formed on the surface of the cellulose. The product thus obtained is subjected to vacuum paper making to obtain wet paper-like fiber, which can be used as a filter aid. This filter aid having reformed surface charge permits filtering at a high rate a liquid which is difficult to filter, such as sediment- containing sake.
