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.
Claims12
A system 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 by the interaction of the activator and the tethering material.
A method for manufacturing a paper product, comprising:
- activating a first population of fibers in a liquid medium with an activator,
- forming a second population of composite additive particles,
- treating the second population with a tethering material to form tether-bearing composite additive particles, wherein the tethering material is capable of interacting with the activator,
- adding the second population to the activated population of fibers to form a treated paper matrix, and
- forming the treated paper matrix to manufacture the paper product.
