Abstract:
A non-oil-based release aid used in a creping process for releasing a paper web from a Yankee dryer in the manufacture of a paper product having a formula for its block version as follows: where R is a C to C alkyl or alkylaryl group, y plus z is greater than 20, and y is greater than z. The y moles of propylene oxide (OC H ) and the z moles of ethylene oxide (OC H ) may be added in random or block fashion. Examples of the chemical compound for the release aid are alkoxylated alkylphenols, alkoxylated fatty acids, and alkoxylated alcohols. A preferred chemical compound is an alkoxylated tall oil fatty acid. The release aid may optionally comprise from about 0% to about 20% by weight of an emulsifying surfactant. The release aid may comprise 70% to 100% by weight of the chemical compound, 0% to 20% by weight of emulsifying surfactants, and 0% to 10% by weight water. The release aid provides lubrication between the doctor blade and the Yankee dryer; allows the release of the paper web from the Yankee dryer, and improves the absorbency of the paper product.
