摘要： 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% to about 25% by weight pulp-derived papermaking fiber and from about 10% to about 75% by weight fibrillated regenerated cellulosic microfiber having a 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/m2, an SAT rate in the range of 0.05-0.25 g/s0.5, 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 have enough absorbent capacity for use as ordinary paper towels. Preferred products exhibit a differential pore volume for pores under 5 microns in diameter of at least about 75 mm3/g/micron.

摘要： An absorbent paper sheet for tissue or towel includes from about 99 percent to about 70 percent by weight of cellulosic papermaking fiber and from about 1 percent to about 30 percent by weight fibrillated regenerated cellulose microfiber which was regenerated form a cellulosic dope utilizing a tertiary amine N-oxide solvent or an ionic liquid. Fibrillation of the microfiber is controlled such that it has a reduced coarseness and a reduced freeness as compared with unfibrillated regenerated cellulose microfiber from which it is made and provides at least one of the following attributes to the absorbent sheet: (a) the absorbent sheet exhibits an elevated SAT value and an elevated wet tensile value as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (b) the absorbent sheet exhibits an elevated wet/dry CD tensile ratio as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (c) the absorbent sheet exhibits a lower GM Break Modulus than a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber; or (d) the absorbent sheet exhibits an elevated bulk as compared with a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber. In some embodiments, the pulp is pre-treated with debonder to enhance the wet/dry CD tensile ratio of the sheet.
