Abrégé
A system for treating recycled cellulosic fibers to improve paper, board and tissue quality; the system involves fractionating recycled fibers into a short fiber portion and a long fiber portion. The short fiber portion is split into an original short fiber portion and a refinable portion. The refinable portion is processed into glue pulp. The glue pulp is refined to targeted, measured fiber properties. Varying amounts of the glue pulp, original short unrefined fibers, and long unrefined fibers are blended together to form an optimized slurry that is processed by a paper machine into an optimized recycled paper product. The process provides for improved drainage with the same or better paper properties allowing for cost reductions in fabrication.

Abrégé
A system for treating cellulosic fibers to improve paper, board and tissue quality; the system involves splitting fibers into an original portion having original fibers and a refinable portion. The refinable portion may further be fractionated by one or more fibers properties by a fiber fractionation system into a first fraction and a second fraction. The refinable portion as a whole, or a fractionated fraction thereof, is then refined to produce refined fibers. Varying amounts of the original unrefined fibers, refined fibers and possibly additionally fractionated unrefined fibers are blended together to form an optimized slurry that is processed by a paper machine into an optimized paper product. A master control system, fiber measurement system and optional fractionation maintenance system may be integrated with the overall system to regulate all processing.

Abrégé
A method for treating cellulosic fibers to improve paper, board and tissue quality; the method involves splitting fibers from feed pulp into an original portion containing original fibers and a refineable portion containing original fibers. The refinable portion is refined to create a refined portion containing refined fibers. Varying amounts of the original unrefined fibers and refined fibers are blended together to form a recombined slurry that is processed by a paper machine into an optimized paper product. A master control system and fiber measurement system are integrated with the overall system to regulate all processing.
