Abstract

The invention provides a method for manufacturing tissue paper. According to the method, a yankee dryer adhesive composition is applied to a metal surface of a drying drum. The yankee dryer adhesive composition preferably includes from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 of at least one monomer selected from the group consisting of vinylformamide, vinyl acetate and vinyl alcohol. The yankee dryer adhesive composition is contacted with a continuous paper web. The continuous paper web is then dried. The dry continuous paper web is creped with a metal blade to form tissue paper.

Claims

1. A method for manufacturing tissue paper, the method comprising the steps of:

a) applying a yankee dryer adhesive composition to a metal surface of a drying drum, the yankee dryer adhesive composition is a crosslinked polymer including from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 of at least one monomer selected from the group consisting of vinylformamide, vinyl acetate and vinyl alcohol;

b) contacting the yankee dryer adhesive composition with a continuous paper web;

c) drying the continuous paper web; and

d) creping the dry continuous paper with a metal blade to form tissue paper.

2. The method of claim 1 where the polymer contains from about 50 to about 99 mole percent of vinylamine.

3. The method of claim 1 where the polymer is a copolymer which contains from about 10 to about 90 mole percent of vinylformamide.

4. The method of claim 1 where the polymer contains from about 80 to about 99 mole percent of vinylamine.

5. The method of claim 1 where the polymer is a homopolymer of polyvinylamine.

6. The method of claim 1 wherein the polymer is crosslinked with one crosslinking agent selected from the group consisting of glutaraldehyde, glyoxal and epichlorohydrin.

7. The method of claim 1 wherein the polymer is crosslinked with from about 0.1 to about 5 mole percent of a crosslinking agent based on the total amine.

13. The method of claim 1 wherein the polymer is crosslinked with glutaraldehyde.

14. The method of claim 1 wherein the polymer is crosslinked with from about 0.5 to about 3 mole percent of a crosslinking agent based on the total amine.

8. A method for manufacturing tissue paper, the method comprising the steps of:

a) applying a yankee dryer adhesive composition to a metal surface of a drying drum, the yankee dryer adhesive composition is a polymer including from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 of at least one monomer selected from the group consisting of vinylformamide, vinyl acetate and vinyl alcohol;

b) contacting the yankee dryer adhesive composition with a continuous paper web;

c) drying the continuous paper web; and

d) creping the dry continuous paper with a metal blade to form tissue paper.

9. The method of claim 8 where the polymer contains from about 50 to about 99 mole percent of vinylamine.

10. The method of claim 8 where the polymer is a copolymer which contains from about 10 to about 90 mole percent of vinylformamide.

11. The method of claim 8 where the polymer contains from about 80 to about 99 mole percent of vinylamine.

12. The method of claim 8 where the polymer is a homopolymer of polyvinylamine.
