    摘要: Methods to control organic contaminants in fibers are described. One method involves contacting the fibers with a) at least one zeolite and optionally b) detackifier, or an ester hydrolyzing enzyme, or both, for a sufficient time and in a sufficient amount to control the organic contaminants present in the fibers. This method is effective to reduce stickies in paper mill furnish formed with recycled fibers. A method for pitch control in paper mill furnish formed with virgin fibers is also provided. Resulting paper products formed from the processed fibers are also described as well as methods to make them.

    摘要: Deinking of waste paper is obtained with the use of a hydrophobic kaolin-based deinking composition. The hydrophobic kaolin-based deinking composition is produced by hydrophobizing the kaolin clay and then blending the hydrophobic kaolin-based particles with a deinking surfactant. Separation and removal of ink is achieved either by washing deinking, flotation deinking or combination of these methods.

    摘要: A method for repulping a wet strength paper is disclosed. Wet strength paper, which contains a wet strength resin, is agitated in water to form an aqueous slurry. An effective amount of a composition that contains a dry mixture of a persulfate and a base in the range of 90:10 to 10:90 is added either before or during agitation, and the slurry heated to produce pulp product for paper manufacture. The persulfate/base combination is capable of breaking down the wet strength resin and adjusting or maintaining the pH at a predetermined level without additional chemical treatment.
