<P>PROBLEM TO BE SOLVED: To provide a cellulose fiber sheet with high strength obtained by allowing cellulose fiber to contain a specific cationic polyacrylamide-based resin. <P>SOLUTION: A cellulose fiber sheet is obtained by using cellulose fiber comprising: a cationic polyacrylamide-based resin having a viscometric average molecular weight measured by an intrinsic viscosity method of 5,000,000 or more and a cationic charge density of 0.5 to 1.5 meq/g; and a cationic polyacrylamide-based resin having a cationic charge density of 1.5 to 3.0 meq/g. <P>COPYRIGHT: (C)2012,JPO&INPIT |
