Claims

What is claimed is:

1. A creping aid composition, said creping aid composition comprising: from about 30% to 90% of a polyvinyl alcohol having a degree of hydrolysis of about 86% or greater and from about 10% to 70% of a non-thermosetting cationic resin containing no secondary amines, said non-thermosetting cationic resin derived from reacting the polyamides of a dicarboxylic acid and methyl bis(3-aminopropyl)amine in aqueous solution with epichlorohydrin in a mole ratio of between about 1:0.1 and about 1:0.33.

2. The creping aid composition of claim 1, further comprising:

a plasticizer, wherein said plasticizer is selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, dipropylene glycol and glycerol.

3. The creping aid composition of claim 2 wherein said plasticizer comprises from about 0.5% to 90% of said creping aid composition based on the dry weight of said plasticizer relative to the dry weight of said creping aid composition.

4. The creping aid composition of claim 1 wherein said non-thermosetting cationic resin has a viscosity at 25.degree. C. of about 20 centipoise to 500 centipoise.

5. The creping aid composition of claim 1 wherein said non-thermosetting cationic resin has a total solids content of about 12% to 30% based on the dry weight of said non-thermosetting cationic resin.

6. A creping aid composition, said creping aid composition comprising:

a) about 5% to 95% of a polyvinyl alcohol,
b) about 5% to 90% of a non-thermosetting cationic resin containing no secondary amines, said non-thermosetting cationic resin derived from reacting the polyamides of a dicarboxylic acid and methyl bis(3-aminopropyl)amine in aqueous solution with epichlorohydrin in a mole ratio of between about 1:0.1 and about 1:0.33, and
c) about 0.5% to 90% of a plasticizer.

7. The creping aid composition of claim 6 further comprising:

a plasticizer, wherein said plasticizer is selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, dipropylene glycol and glycerol.

8. The creping aid composition of claim 6 wherein said polyvinyl alcohol has a degree of hydrolysis of about 86% or greater.

9. The creping aid composition of claim 6 wherein said non-thermosetting cationic resin has a viscosity at 25.degree. C. of about 20 centipoise to 500 centipoise.

10. The creping aid composition of claim 6 wherein said non-thermosetting cationic resin has a total solids content of about 12% to 30% based on the dry weight of said non-thermosetting cationic resin.
