1. A process for making fluff pulp, comprising: contacting a first aqueous slurry comprising softwood fibers with a second aqueous slurry comprising hardwood fibers, to form a furnish; contacting the furnish onto a moving wire, to form a web; drying and optionally pressing the web, to form the fluff pulp comprising softwood fibers and from 8 to 23% by weight hardwood fibers; fiberizing the fluff pulp; and contacting the fiberized fluff pulp with one or more superabsorbent polymers. 2. The process of claim 1, comprising pressing the web. 3. The process of claim 1, further comprising rolling the fluff pulp onto a roll or cutting the fluff pulp into sheets, and stacking the sheets to form a bale. 4. The process of claim 1, wherein said drying comprises flash drying the web to form the fluff pulp, and thereafter bagging the fluff pulp. 5. The process of claim 1, further comprising contacting the first and second slurries at a blend chest. 6. The process of claim 1, further comprising and prior to contacting the first and second slurries: forming the hardwood fibers by one or more steps selected from the group consisting of chipping, pulping, and bleaching hardwood, or a combination of two or more thereof; and forming the softwood fibers by one or more steps selected from the group consisting of chipping, pulping, and bleaching softwood, or a combination of two or more thereof. 7. The process of claim 1, which is carried out in an airlaid line. 8. The process of claim 1, further comprising taking the fluff pulp from a bale, roll, or bag, or combination thereof, and fiberizing. 9. The process of claim 1, further comprising after contacting the fiberized fluff pulp and the one or more superabsorbent polymers, forming a second web, and densifying the second web in a nip. 10. The process of claim 1, wherein the contacting is carried out in an airlaid line. 11. A process for making an absorbent product comprising a core having the fiberized fluff pulp and one or more superabsorbent polymers of claim 1 and a supporting structure, comprising contacting at least a portion of the core with the supporting structure.
