Adhesive Testing of Chemical Additives Applied to Yankee Dryers, 1990 Nonwovens Conference Proceedings
In tissuemaking, various chemical aids may be used in building and controlling the coating which is required on the Yankee dryer surface. One function of the coating is to aid in developing the crepe which is characteristic of a tissue sheet, and results in desired properties such as softness, bulk, and stretch. An important factor in the ability of the coating to provide the desired crepe is the adhesion developed between the tissue and the Yankee surface. This paper describes a laboratory method which has been used to characterize the adhesive properties exhibited by some commonly used creping chemicals. The test method shows promise as an effective screening tool for Yankee adhesive chemistries. From the results observed thus far significant opportunities exist to tailor the chemistry of creping aids to meet the adhesive needs of a particular mill or tissue machine.
