Abstract:
The invention is directed to systems for papermaking comprising a first population of fibers dispersed in an aqueous solution and complexed with an activator, and a second population of composite additive particles bearing a tethering material, wherein the addition of the second population to the first population attaches the composite additive particles to the fibers. The invention also encompasses methods for manufacturing a paper product.
