摘要
The intrinsic tissue sheet properties of tissue sheets wound into a parent roll during manufacturing can be purposely varied in order to provide a z-directional gradient within the parent roll. For example, the moisture content of the tissue sheet can be made lower in the core region of the parent roll and greater in the outer region of the parent roll. Such gradients can ultimately provide more uniformity of the intrinsic property within the final tissue product.
