Abstract
The present disclosure provides methods of improving dewatering in the papermaking process by incorporation of functionalized cellulose fibers in the paper furnish. Additionally, the disclosure provides the means to eliminate process problems mainly plugging problems in a nano/micro-fibrillated cellulose production process by incorporation of functionalized cellulose fibers in a cellulose fiber composition and methods of functionalizing cellulose fibers in a paper making process. The methods according to the present disclosure provide several advantages, such as improving the freeness and dewatering of the paper making process during the paper making process, leading to an increased production rate and reduced energy consumption.
