Creping Release Agent (Tissue Yankee)
Creping release agents are applied to the Yankee dryer in tissue paper manufacturing to balance the adhesion of the creping adhesive, allowing controlled release of the paper web at the doctor blade for uniform creping. They are typically based on polyols, fatty acids, or mineral oil dispersions and are dosed in opposition to the adhesive to achieve the optimal adhesion-release balance for target tissue softness and crepe structure.
