Claims10
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.
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.
