Abstract
The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. Preferably the creping composition comprises a first component that is cationic and a second component that is capable of forming a film. Preferably both the first and second components are water soluble. The first component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained. The overall retention of the creping composition reduces the concentration of the composition in the machine process water, improving machine operability and runability.
