How It Helps
The use of creping aids provides the following benefits:
- Creation of an interface between the tissue and the Yankee drying cylinder to protect the Yankee drying cylinder from wear and corrosion from the doctor blade.
- Creation of a medium to improve sheet structure and crepe formation.
- Improved sheet breakdown to give better surface softness by creating a finer crepe.
- Improved bulk softness due to better crepe microfolds and macrofolds during the creping process.
- Improved blade wear and tear and gives better blade life.
- Allows the mill to make added-value tissue products.
Application Areas
Most creping and release products are applied by the use of a spray to the Yankee surface using a dedicated spray bar and spraying rig.
In tissue mills, using an Infrared thermal camera (shown below) can help create real-time images, which in turn help to select the right creping program. We conduct technical audits using Infrared technology as a diagnostic tool to improve creping, felt cleaning and wire cleaning operations. Infrared also helps improve the creping process and reduce the moisture variations in the reel by highlighting other problem areas in the Yankee and around the system. In addition to using Infra-Red, stroboscopic detection techniques (via videos) are also used to identify problem areas.
