High bulk high strength fiber material with permanent fiber morphology

Wood fiber morphology can be permanently altered by introducing a substantial kink, twist, curl, crimp or other curvilinear deformation into a wood fiber. Wood fibers are first Fiberized using mechanical treatment processes and then are subjected to super atmospheric temperature/pressure steam explosion processing. The fiber morphology becomes a permanent characteristic of the fiber which is not relaxed in time, by contact with other treatments or through use.
