Claims
- 1. A process for making a cellulosic pulp fiber web having increased wet strength comprising the steps of: (1) adding to an aqueous cellulosic pulp fiber slurry a water soluble cationic polymer consisting of polydimethyldiallylammonium chloride to form a first treated slurry; (2) adding to said first treated slurry an amount of aminopolyamide-epichlorohydrin acid salt resin solution having an EiN ratio of from about 0.6 to about 2.0 so that the weight percent of said cationic polymer is from about 1% to about 35% by weight based on the weight of said resin to form a second treated slurry; and (3) forming a cellulosic pulp fiber web by dewatering said second treated slurry.
- 2. The process of claim 1 wherein said E/N ratio is from about 0,6 to about 1.0.
- 3. The process of claim 1 wherein said E/N ratio is about 1.0.
- 4. The process of claim 1 wherein the amount of said cationic polymer is from 5% to about 15% by weight based on the weight of said resin.
- 5. The process of claim 4 wherein the amount of said cationic polymer is about 10% by weight based on the weight of said resin.
- 6. A process for making a cellulosic pulp fiber web having increased wet strength comprising the steps of: (1) adding to an aqueous cellulosic pulp fiber slurry a composition comprising a aminopolyamide-epichlorohydrin acid salt resin solution having an E/N ratio of from about 0.6 to about 2.0 and from about 1% to about 35% by weight of a water soluble cationic polymer consisting of polydimethyldiallylammonium chloride, based on the weight of said resin, to form a treated slurry; and (2) forming a cellulosic pulp fiber web by dewatering said treated slurry.
- 7. The process of claim 6 wherein said E/N ratio is from about 0,6 to about 1.0.
- 8. The process of claim 6 wherein said E/N ratio is about 1.0.
- 9. The process of claim 6 wherein the amount of said cationic polymer is from 5% to about 15% by weight based on the weight of said resin.
- 10. The process of claim 9 wherein the amount of said cationic polymer is about 10% by weight based on the weight of said resin.
