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 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.

Method of increasing efficiency of chemical additives in a papermaking system

A method is provided for the improvement of fabric release in applications such as tissue and towel making processes. The method comprises applying a micro-emulsion of hydrophobic agents and surfactants to the surface of a structured fabric used in sheet making applications of a tissue machine.

Method for improving fabric release in structured sheet making applications

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 method of measuring hydrophobic contaminants in a pulp slurry or a papermaking system includes the steps of providing an aqueous paper mill sample, filtering the aqueous paper mill sample to produce a filtrate comprising particles, and collecting an image of the particles in a measured volume of the filtrate. The method also includes the steps of analyzing the image to determine a size and morphology of the particles in the measured volume of filtrate, identifying spherical particles having a size of from about 1 micron to about 20 microns in the measured volume of filtrate, and quantifying a number of the spherical particles having the size of from about 1 micron to about 20 microns in the measured volume of filtrate. This method is useful for papermakers for deposition diagnostics, prevention, and contaminant control treatment optimization.

The present invention provides for a method of producing a creped paper and the crepe paper products made using this method. The method includes treating the surface of a crepe fiber web and/or surface of a Yankee drum dryer or cylinder with compositions containing a combination of hydrophobes and surfactants and wherein these compositions have been subjected to physical treatments to reduce the mean particle size to about 1 micron (&#x3bc;m) or less.

Method of producing a creping paper and the creping paper thereof

Compositions and methods for reduction in adhesion between wet paper web and roll surfaces in papermaking process are disclosed. The method is particularly useful for improvements in press section roll release.

Papermaking additives for roll release improvement

Compositions and methods for the removal of resin from wood chips processed in a Kraft pulping process are disclosed. The method is particularly useful for removing triterpene and triterpenoid resin.
