Method of improving dewatering efficiency, increasing sheet wet web strength, increasing sheet wet strength and enhancing filler retention in papermaking

A method of papermaking comprising the use of filler, the method comprising the steps of:

• providing a blend of filler particles, at least one drty strength aid, and cellulose fiber stock,
• treating the filler particles with a composition of matter in the absence of cellulose fiber stock,
• combining the filler particles with the cellulose fiber stock,
• treating the combination with at least one dry strength aid, and
• forming a paper mat from the combination,
• wherein at least 10% of the filler particles are in a dispersed slurry calcium carbonate form,
• the cellulose fiber stock comprises a plurality of cellulose fibers and water, and
• the composition of matter enhances the performance of the dry strength aid in the paper mat.

A method of increasing the interactions between a drainage additive or wet web strength additive or wet strength aid and cellulose fibers mixed with filler particles, the method comprising the steps of:

• pre-treating filler particles with a composition of matter in the absence of cellulose fiber stock,
• combining the pre-treated filler particles with cellulose fibers, and
• treating the combination with at least one drainage additive or wet web strength additive or wet strength aid,
• wherein the filler particles are selected from the list consisting of precipitated calcium carbonate, ground calcium carbonate, and any combination thereof, and
• the composition of matter inhibits the drainage additive or the wet web strength additive or wet strength aid from adhering to the filler particles.
