A method of making a wiper/towel product includes compactively dewatering a nascent web having cellulosic microfibers and an apparently random distribution of fibers. The dewatered web is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a creping belt. The belt-creping step occurs under pressure in a belt creping nip. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the hollow domed regions.

A method of making a wiper/towel product includes compactively dewatering a nascent web having cellulosic microfibers and an apparently random fiber distribution. The dewatered web is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a polymeric creping belt having perforations. The belt-creping step occurs under pressure in a belt creping nip. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the domed regions.

A method of making a multi-ply wiper/towel product with cellulosic microfibers. The method includes compactively dewatering a nascent web that includes at least about 10% fibrillated cellulosic microfibers and has an apparently random distribution of fibers. The dewatered web having the apparently random distribution of fibers is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the belt. The belt-creping step occurs under pressure in a belt creping nip defined between the transfer surface and the creping belt. The web is dried to form a dried web that includes a plurality of fiber-enriched hollow domed regions protruding from an upper side of the dried web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions of the dried web, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the hollow domed regions formed along at least the leading edge thereof.

A multi-ply wiper/towel product includes at least one wet laid web having at least 10% fibrillated cellulosic microfiber, and at least about 40% wood pulp derived papermaking fibers. The at least one wet laid web has formed therein (i) a plurality of fiber-enriched hollow domed regions on the upper side of the at least one wet laid web having a relatively high local basis weight, (ii) connecting regions having a relatively lower local basis weight forming a network interconnecting the relatively high local basis weight domed regions of the one wet laid web, and (iii) transition areas with upwardly and inwardly inflected consolidated fibrous regions transitioning from the connecting regions into the domed regions.

A system may include a plurality of tow band processing lines and a master air jet in communication with the tow band processing lines to receive a plurality of processed tow bands from the tow band processing lines to form a bulked web. The system may be used to form a bulked web that itself is a nonwoven material or that may be further processed into a nonwoven material.

Methods for producing nonwoven materials from continuous tow bands

A multi-ply wiper/towel product includes at least one wet laid web including at least 10% fibrillated cellulosic microfiber, and at least about 40% wood pulp derived papermaking fibers. The at least one wet laid web has formed therein (i) a plurality of fiber-enriched hollow domed regions on the upper side of the at least one wet laid web having a relatively high local basis weight, and (ii) connecting regions of a relatively lower local basis weight forming a network interconnecting the relatively high local basis weight domed regions of the one wet laid web. Transition areas are provided in the at least one wet laid web with upwardly and inwardly inflected consolidated fibrous regions transitioning from the connecting regions into the domed regions, and the at least one wet laid web exhibits a differential pore volume for pores under 5 microns in a diameter of at least about 75 mm/g/micron.

A cleaning system having pulverulent foaming cleanser (e.g., acid, alkali metal carbonate and surfactant) is sealed within a water soluble (e.g., PVOH) deformable pouch frictionally retainable within the core of a roll of bath tissue. Upon placement of the pouch in the bowl, water in the bowl penetrates the water soluble wall of the pouch, generating foam which provides cleaning action by activating and carrying cleansing chemicals, not only below the water line of the bowl, but also considerably above it. When used routinely with each change of bath tissue roll, such a cleaning can extend the time between required manual cleanings considerably.
