A method of making fiber bundles and fibrous structures. The efficacy of a fiber bundle in handling complex fluids may be improved by subjecting an aqueous suspension of fibers at high consistency to elevated energy input with sufficient working of the fibers. The fibrous structures prepared according to the methods herein include at least one fiber bundle and at least one debonding agent. The fiber bundle includes at least one particulate material consisting essentially of entangled fibers.

1. A method of making fibrous structures, the method comprising (a) forming an aqueous suspension of fibers having an inlet consistency of at least about 20 weight percent, (b) adding a debonding agent to the aqueous suspension and (c) subsequently passing the aqueous suspension through a disperser

1. A method of making fibrous structures, the method comprising (a) forming an aqueous suspension of fibers having an inlet consistency of at least about 20 weight percent, (b) adding a debonding agent to the aqueous suspension and (c) subsequently passing the aqueous suspension through a disperser with an energy input of at least about 90 kW-h/T of dry fiber to form fibrous structures that are extruded from the disperser, wherein the fibrous structures exhibit a complex fluid retention capacity that is at least about 20 percent greater than the complex fluid retention capacity exhibited by an otherwise substantially similar fibrous structure that does not include a debonding agent.
