Soft, absorbent sheets having high absorbency and high caliper, and methods of making soft, absorbent sheets
Paper products, such as hand towels, have high absorbency, high caliper, and good perceived softness. Two-ply products have a caliper of at least about 260 mils/8 sheets and an SAT capacity of at least about 650 g/m 2 . The paper products are made using a structuring fabric that has a high planar volumetric index, which indicates a relation between the contact area ratio of a papermaking web contacting surface of the structuring fabric and the volume of pockets of the fabric.
