Abstract:

Compositions of and processes for preparing a polyamine-polyamidoamine-epihalohydrin resin generally include reacting a first polyamine, a polyamidoamine, and an epihalohydrin to form the polyamine-polyamidoamine-epihalohydrin (PPAE) resin, wherein the polyamidoamine is prepared by reacting a polycarboxylic acid or a polycarboxylic acid derivative with a second polyamine to form the polyamidoamine, wherein a molar ratio of the polyamine to the polycarboxylic acid is 1.05 to 2.0. The PPAE resin can be used in an adhesive formulation for use in creping applications for forming paper products such as tissue products.

Assignee:

KEMIRA OYJ - Helsinki

International Classification:

G01H 13/00

US Classification:

523400, 73579

Abstract:

Described herein are quartz crystal microbalance (QCM) and quartz crystal microbalance with dissipation (QCMD) techniques that can be used for measuring characteristics of a creping adhesive film similar to the creping adhesive film that is formed on a Yankee dryer during the tissue and towel manufacturing process. In addition, exemplary embodiments described herein may use these techniques to predict performance of creping aids utilized to form a creping adhesive film.
