Method of improving wet tensile strength of paper |
| abstract |
ABSTRACT OF THE DISCLOSURE Method and composition for improving the wet tensile strength of paper. The method involves treating paper pulp with pH-adjusted polyurethane prepolymer amine salt and then producing paper from the treated pulp. The polyurethane prepolymer amine salt has an unadjusted pH of about 3.5-5.5. After adjustment, the pH of the amine salt can range from 6.0 to 9Ø |
