Abstract
Abstract Uncreped throughdried basesheets can be made with the caliper of the basesheet being independent of the basis weight of the basesheet. Multi-ply wipers and towels produced by plying together two or more of such basesheets having a relatively low basis weight can provide products with improved caliper and absorbency for a given strength level and the amount of fiber used.
