Repeatable and reliable chemical treatment for loose fibers is achieved by spraying or immersing loose fibers in a chemical treatment bath, and continuously moving the soaked fibers through a continuous centrifuge. The continuous centrifuge controls the wet pickup of the chemical formulation on the fibers and assures a substantially even chemical distribution on the centrifuged fibers. The centrifuged fibers may be dried to fix the chemicals in the chemical formulation to the fibers and/or to remove water from the chemical formulation. Recycling of the chemical formulation from the continuous centrifuge allows for the process to be performed more economically and in a more environmentally friendly fashion.
