Abstract
A tufted nonwoven web material exhibiting high loft, bulk and absorbency is made by a papermaking technique using an apertured, plate-like, fiber collecting element having a structure appropriate to preventing entanglement between adjacent tufts prior to removal from the element. The tufted nonwoven fibrous web exhibits inwardly turned, spirally consolidated and entangled individual tuft head portions and substantially aligned and untwisted root portions interconnecting the head portion to the undisturbed planar main body of the web material.
