Abstract
A method for producing creped paper products comprising applying to a drying surface, a film-forming semi-crystalline polymer and a non-thermosetting cationic resin containing no secondary amine. The invention also comprises a method for producing creped paper products comprising applying to a drying surface a film-forming semi-crystalline polymer, a non-thermosetting cationic resin containing no secondary amines and an optional plasticizer.
Claims17
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 one of said fibrous structure, said creping aid 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-aminopropylamine) in aqueous solution with epichlorohydrin in a mole ratio of between about 1:0.1 and about 1:0.33;
- d) applying a fibrous structure to said drying surface whereby said fibrous structure contacts said creping aid;
- e) removing said fibrous structure from said drying surface.
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 one of said fibrous structure, said creping aid comprising:
- i) about 5% to 95% of a polyvinyl alcohol,
- ii) 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-aminopropylamine) in aqueous solution with epichlorohydrin in a mole ratio of between about 1:0.1 and about 1:0.33, and
- iii) about 0.5% to 90% of a plasticizer;
- d) applying a fibrous structure to said drying surface whereby said fibrous structure contacts said creping aid;
- e) removing said fibrous structure from said drying surface.
