Abstract
A method for creping paper includes applying an adhesive composition to an outer surface of a creping cylinder (Yankee cylinder) to form an adhesive coating, contacting paper with the adhesive coating, removing the paper and adhesive coating from the creping cylinder, and determining a quality of the adhesive coating. Determining the quality of the adhesive coating may include measuring a degree of cross-linking of the adhesive polymer, a concentration of the adhesive polymer in the adhesive coating, a water content of the adhesive coating, an ash content of the adhesive coating, or combinations thereof. Determining the quality of the adhesive coating may also include determining a thickness of the adhesive coating by measuring light absorbed by the coating and calculating the thickness using Beer's Law. Systems and apparatuses for determining the quality of the adhesive coating and for creping paper are also disclosed.
