Claims

What is claimed is:

1. A method for producing paper products, said method comprising the steps of:

a) providing a fibrous structure;
b) providing a drying surface;
c) applying a creping aid whereby said creping aid contacts one of said drying surface and said fibrous structure, said creping aid comprising a film-forming semi-crystalline polymer and a non-thermosetting cationic resin wherein said non-thermosetting cationic resin is characterized by a highly branched structure that lacks reactive intralinker functionality and which has a prepolymer backbone comprised of endcapped polyamidoamine wherein said endcapped polyamidoamine prepolymer comprises the reaction product of at least one dicarboxylic acid or dicarboxylic acid derivative, at least one polyamine, and at least one endcapping agent wherein said endcapping agent comprises at least one member selected from the group consisting of monofunctional amines, monofunctional carboxylic acids, and monofunctional carboxylic acid esters and wherein said endcapped polyamidoamine prepolymer is free or substantially free of amine and carboxyl end groups;
d) drying said fibrous structure on said drying surface; and
e) removing said fibrous structure from said drying surface.

2. The method of claim 1 wherein said step of applying said creping aid comprises applying said creping aid directly to said drying surface.

3. The method of claim 1 wherein said fibrous structure has a first surface and a second surface wherein said second surface contacts said drying surface, and wherein said creping aid is applied directly to said second surface of said fibrous structure.

4. The method of claim 1 wherein said step of applying said creping aid comprises applying said creping aid directly to a forming fabric.

5. The method of claim 1 wherein said step of applying said creping aid comprises applying said creping aid directly to a foraminous carrier fabric.

6. The method of claim 1 wherein said drying surface is heated.

7. The method of claim 1 wherein said step of removing said fibrous structure from said drying surface is accomplished by creping.

8. The method of claim 1 wherein said creping aid is applied at a rate of from about 0.25 to 8.5 pounds of dry weight of the total applied creping aid per ton of dry fiber produced at a reel of a paper machine.

9. The method of claim 1 wherein said creping aid further comprises a plasticizer.

10. The method of claim 9 wherein said plasticizer is selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, dipropylene glycol and glycerol.

11. The method of claim 1 wherein said fibrous structure has a moisture content of between about 10% to about 90% upon contact with said drying surface.
