[ I claim:] [1.] In a process for making a dried fluff pulp sheet from a chemical pulp slurry which comprises the steps of sheet formation, pressing and drying, the improvement comprising mildly refining the chemical pulp slurry prior to sheet formation, whereby the chemical pulp slurry is refined sufficient to produce a dried fluff pulp sheet from which a fluffed pulp is prepared having improved dry compression characteristics relative to a fluff pulp similarly prepared without any refining; and wherein the chemical pulp slurry is refined sufficient to produce a dried fluff pulp sheet having a burst index value between about 0.5 and about 3.0 kPa m.sup.2 /g and a density between about 0.4 and about 0.7 g/cm.sup.3.
