A foaming formulation is provided herein. The foaming formulation includes at least one foaming agent in an amount of from about 0.001% to about 10% by weight based on a total weight of the foaming solution. The foaming formulation further includes a synthetic strength additive having a cationic functional group in an amount from about 0.01% to about 50% by weight based on a total weight of the foaming solution. The foaming formulation further includes water.

Foam assisted application of strength additives to paper products

A method of increasing chemical efficiency of chemical additives in a papermaking system includes the steps of providing thick stock pulp comprising soluble lignin, process water, and at least about 2% by weight of cellulosic fiber based on total weight of thick stock pulp, and adding at least one laccase enzyme and at least one organic polymer to the thick stock pulp to reduce the amount of soluble lignin therein. The organic polymer is chosen from cationic polymers, non-ionic polymers and combinations thereof.

Chemical efficiency increase in papermaking process

A graft copolymer composition of a vinyl monomer and a functionalized vinylamine-containing base polymer and a method of preparing the graft copolymer. It also relates to a paper product made using the composition as a papermaking additive.

Modified vinylamine containing polymers and their use in papermaking

A method of improving dry strength and/or drainage of a paper or paperboard by adding to a paper or paperboard furnish, a graft copolymer composition of a vinyl monomer and a functionalized vinylamine-containing base polymer graft copolymer.

Modified of improving dry strength and/or drainage of a paper or paperboard

Provided is a method of making paper and paperboard. In particular graft copolymers of vinyl monomers and functionalized vinylamine-containing base polymers by Michael addition are added to a paper furnish. The composition can be used alone or in combination with other additives for use in paper making and to improve paper making processes such as paper dry and wet strength properties.
