    摘要: 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. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side. In one embodiment, tissue webs made according to the present invention may also be splittable, allowing the web to be pulled apart in two substantially continuous webs with distinctly different properties.

    摘要: Topically-applied binder materials for imparting wet strength to soft, absorbent paper sheets, such as are useful as household paper towels and the like, include an azetidinium-reactive polymer, such as a carboxyl-functional polymer, an azetidinium-functional polymer and, optionally, a component useful for reducing sheet-to-sheet adhesion (blocking) in the product. These binder materials can be cured at ambient temperature over a period of days and do not impart objectionable odor to final product when wetted.
