surface of the wipe/towel product, the hollow domed regions having a sidewall of a relatively high local basis weight formed along at least a leading edge thereof; and (ii) connecting regions of a relatively lower local basis weight forming a network interconnecting the fiber-enriched hollow domed regions of the wiper/towel product, wherein consolidated groupings of fibers extend upwardly from the connecting regions into the sidewalls of the fiber-enriched hollow domed regions along at least the leading edge thereof, and wherein the wiper/towel product exhibits a relative wipe dry time that is less than 50% of the wipe dry time exhibited by a conventional wipe of the same fibrous composition, but without fibrillated cellulosic microfibers. ### Claim 86 (depends on 85) The multi-ply wiper/towel product of claim 85, wherein the product exhibits a differential pore volume for pores under 5 microns in a diameter of at least about 100 mm3/g/micron. ### Claim 87 (depends on 85) The multi-ply wiper/towel product of claim 85, wherein the product exhibits a relative wipe dry time that is less than about 40% of the wipe dry time exhibited by a conventional wipe of the same fibrous composition, but without fibrillated cellulosic microfibers. ### Claim 88 A multi-ply absorbent sheet comprising: at least one wet laid web comprising at least 10% fibrillated cellulosic microfibers and at least about 40% wood pulp derived papermaking fibers, the absorbent sheet comprising a wiper/towel product being formed with upper and lower surfaces having formed therein: (i) a plurality of fiber-enriched hollow domed regions protruding from the upper surface of the wiper/towel product, the hollow domed regions having a sidewall of a relatively high local basis weight formed along at least a leading edge thereof; and (ii) connecting regions of a relatively lower local basis weight forming a network interconnecting the fiber-enriched hollow domed regions of the wiper/towel product, wherein the fibrous composition of the web, the geometry of the fibrillated cellulosic microfibers, and the number average count are chosen such that the wiper/towel product exhibits a wipe dry time of less than about 20 seconds and a differential pore volume of at least about 10% for pores under 5 microns in diameter. ### Claim 89 (depends on 88) The multi-ply absorbent sheet of claim 88, wherein the sheet exhibits a wipe-dry time of at most 10 seconds. ### Claim 90 (depends on 88) The multi-ply absorbent sheet according to claim 88, wherein the sheet exhibits a cross machine direction (CD) wet breaking length in the range of about 300 to about 800 m. ### Claim 91 (depends on 88) The multi-ply absorbent sheet according to claim 88, wherein the sheet exhibits a cross machine direction (CD) wet breaking length in the range of about 400 to about 800 m. ### Claim 92 (depends on 88) The multi-ply absorbent sheet according to claim 88, wherein the sheet exhibits an SAT rate in the range of about 0.05 to about 0.25 g/s0.5. ### Claim 93 (depends on 88) The multi-ply absorbent sheet according to claim 88, wherein the sheet exhibits an SAT capacity in the range of about 9.5 to about 11.0 g/g. ### Claim 94 A multi-ply absorbent sheet comprising: at least one wet laid web comprising at least about 10% fibrillated cellulosic microfibers and at least about 40% wood pulp derived papermaking fibers, the multi-ply absorbent sheet comprising a wiper/towel product being formed with upper and lower surfaces comprising: (i) a plurality of fiber-enriched hollow domed regions protruding from the upper surface of the sheet, the hollow domed regions having a sidewall of a relatively high local basis weight formed along at least a leading edge thereof; and (ii) connecting regions of a relatively lower local basis weight forming a network interconnecting the fiber-enriched hollow domed regions of the sheet, wherein the fibrous composition of the web, the geometry of the fibrillated cellulosic microfibers, and the number average count are chosen such that the multi-ply wiper/towel product exhibits a differential pore volume of at least about 10% for pores under 5 microns in diameter, and an SAT capacity in the range of about 9.5 to about 11.0 g/g. ### Claim 95 (depends on 94) The multi-ply absorbent sheet of claim 94, wherein the sheet exhibits a wipe-dry time of at most 10 seconds. ### Claim 96 (depends on 94) The multi-ply absorbent sheet according to claim 94, wherein the sheet exhibits a cross machine direction (CD) wet breaking length in the range of about 300 to about 800 m. ### Claim 97 (depends on 94) The multi-ply absorbent sheet according to claim 94, wherein the sheet exhibits a cross machine direction (CD) wet breaking length in the range
