Abstract:
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.
