Abstract:
In production of tissue paper, the adhesion of a liquid adhesive creping aid, compound
polymer, as creping aids on the Yankee dryer surface was investigated. A compound
polymer was prepared based on mixing ratio of poly (amideamine)-epichlorohydrin resin
(PAE) as an adhesive agent, polyvinyl alcohol (PVA) as a modifier agent, and cationic
fatty acid (CFA) and ethylene glycol (EG) as release agents. In order to simulate the
Yankee dryer cylinder, the adherence of paper to the substrate that was coated by the
compound polymer solution was measured using a peel strength test. Results indicated
that increasing the percent of total solid content of compound polymer would increase
peel strength of paper. Peel strength of paper increases if EG as a release agent is used.
The amount of PVA/PAE resin in the formulation of creping aid was critical for building
a flexible and tough coating layer on to the substrate and to provide adequate adhesion of
paper in peel strength test.
