Abstract
The present invention uses hydrophobically modified polyaminamide with standard wet strength agent to produce a softer and more absorbent paper material. The hydrophobically modified polyaminamide is substantive to cellulosic fibers, thus is able to carry polyethylene glycol esters or ethers, a non-substantive material to cellulosic fiber as stable complexes, into the paper product.
Claims11
A paper product comprising a complex of nonionic surfactant and polyaminamide hydrophobically modified by reaction with at least one of a group comprising epoxide of a long hydrocarbon, ester of a fatty acid, acylchloride of a fatty acid, or fatty acid.
A method for producing a paper product comprising:
- (a) forming a complex from the addition of nonionic surfactants to polyaminamides hydrophobically modified by reaction with at least one of a group comprising epoxide of a lone hydrocarbon, ester of a fatty acid, acylchloride of a fatty acid, or fatty acid;
- (b) adding a wet strength resin;
- (c) adding said complex to a fiber slurry;
- and
- (d) forming an absorbent paper from said slurry.
