Abstract
A method is disclosed for preparing a quantity of individual treated fibers from one or more fiber mats in a treatment apparatus. The apparatus comprises a fiber treatment zone, a conveyor for conveying each mat through the fiber treatment zone, wherein each mat is impregnated by an applicator with a crosslinking substance, and directly to an attrition device. The attrition device fiberizes the mats to form a fiber output having a low nit level, such as no more than about three, and a dryer for both drying the fiber output and curing the crosslinking substance. The fiberizer is configured to have minimize the accumulation of fiber at locations therein. An optional component of the fiberizer is a novel fluff generator comprised of multiple rotors each having plural longitudinally extended rows of radially extending rotor pins that rotate past groups of shorter pins mounted on the inside surface of the fluff generator housing.
