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.
