Abstract: Methods and compositions for improving a papermaking process are provided herein. The compositions include, for example, an oil, an emulsifying surfactant, and a formulation aid. The methods may include adding an effective amount of the composition to a foraminous surface and contacting the foraminous surface with a furnish. Water may be drained through the foraminous surface, thus forming a sheet on the foraminous surface, which may be transferred to a felt, a belt, a fabric, or elsewhere.

Abstract: The present application is directed to creping adhesives. The adhesive forms from a solution/dispersion of a polyelectrolyte complex that is composed of a mixture of one or more cationic polyelectrolytes, and one or more anionic polyelectrolytes. This adhesive complex offers several desirable features when compared to conventional, non-complex adhesives such as improved coating durability, wet tack and tunable coating softness, which are key properties for an adhesive to function as a creping adhesive.
