A multi-ply absorbent sheet includes at least a first and second ply bonded together. In one construction, the first and second ply are provided with from about 90% by weight to about 25% by weight pulp-derived papermaking fiber and from about 10% to about 75% by weight fibrillated regenerated cellulosic microfiber having a characteristic CSF value of less than 175 ml; the sheet having a caliper of from 180-250 mils/8 sheets and exhibiting a wipe-dry time of less than 20 seconds, an SAT capacity in the range of 350-500 g/m 2 , an SAT rate in the range of 0.05-0.25 g/s 0.5 , a CD wet tensile in the range of 400-2500 g/3″ and a wet/dry CD tensile ratio of from 35% to 60%. The multi-ply sheets are efficient, high capacity wipers and have enough absorbent capacity to be used as ordinary paper towels. Preferred wiper towel products exhibit a differential pore volume for pores under 5 microns in diameter of at least about 75 mm 3 /g/micron. |
