The setup of the coating “layer” is so important that it can make the difference between producing high quality, properly creped tissue in case of a good set up and jeopardizing production or, even, stop the machine to prevent severe damages on the yankee in case of a bad arrangement. What is also well known is that the yankee coating can be influenced both directly, through the nature and dosage of yankee coating chemicals, and indirectly through chemicals added to the process.
Creping efficiency and caliper development are among the most important key process indicators of the tissue creping process. They are both linked to process performance and machine productivity, as tissue makers know very well. We have recently made some valuable experiences under this regard, that we would like to submit to you as case histories.
In this article we want to introduce you to our novel chemicals MARESOFT S 850 and MARERELEASE R 300. The first chemical is used to integrate the yankee coating recipe used on the tissue machine, while the second can be used both to integrate the recipe or to substitute the incumbent release agent. Either way, the chemicals allow the formation of a more uniform, thicker and plastic coating layer, characterized by a lower friction level (Cover picture).
Some case histories follow.
