ABSTRACT:
Magnetic paper-forming fibers have a particulate magnetic material incorporated within the fibers, as distinct from between the fibers; this can be achieved by loading the lumens of cellulosic fibers with magnetic particles or by generating magnetic particles in situ in a paper-forming fiber which contains ionic groups effective for ion exchange with ferrous ions; the fibers can be employed to produce single layer or multi-layererd magnetic papers for information storage, security paper applications, paper handling, reprographic applications such as magnetographic printing substrate as well as for speciality uses such as electromagnetic shielding, magnetic separation of antibodies based on selective adsorption.
