Abstract
Multi-ply paper towels are disclosed which have a combination of high absorbent capacity and a high rate of absorbency. These properties are the result of a combination of the intra-ply fiber structure and a network of inter-ply wet-collapse resistant channels that distribute and retain absorbed liquid.
