Abstract
Free flowing particles useful in absorbent articles are disclosed, including fibrous nits and methods of preparing fibrous nits. In one embodiment, fibrous nits are prepared from disperging cellulosic fibers in the presence of a nit conditioner which modifies nit particle size and properties for improved performance of the particles. In other embodiments, nits are prepared in multiple disperging steps or by disperging fibers under two or more conditions.
