ABSTRACT:
Cellulosic fibers, characterized by a lack of swellability and incapable of natural fiber-to-fiber bonding, are produced by a process which comprises treating an aqueous slurry of the fibers with a formaldehyde-free polymeric compound, heating the treated fibers to cause the polymeric compound to react with the fibers, and refiberizing to separate individual, treated fibers. The fibers are useful in the preparation of improved cellulosic webs characterized primarily by their increased bulk and improved softness.
