Abstract: A debonded cellulose fiber pulp sheet that is adapted to be fiberized by mechanical action to form a fluffy material and is impregnated with small amounts, such as 1% or less, of a long chain fatty alkyl cationic compound having at least 12 carbon atoms in at least one alkyl chain and a similar small or somewhat larger amount of an oily material such as a mineral, vegetable or animal oil which coacts with the cationic compound to render the pulp sheet easily mechanically fiberizable, and the resulting fiberized fluffy material softer, more lofty and more absorbent and method for producing said sheet.
