ABSTRACT:
The present invention is generally directed to paper products having great softness and strength. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. The web can contain softwood fibers in combination with high-yield fibers. For example, the high-yield fibers can be contained in the middle layer of a stratified fiber furnish. In accordance with the present invention, a first bonding material is applied to a first side of the web and optionally a second bonding material is applied to a second side of the paper web. The bonding materials are applied according to preselected patterns. At least one side of the paper web is creped after one of the bonding materials is applied. The bonding material applied to the creped side of the web can be an adhesive selected that allows the web to be creped at relatively low temperatures.
