Abstract
A method is disclosed for application of compositions onto non-woven webs, such as paper webs. The present invention is also directed to products made from the process. In general, the method includes applying a composition to a non-woven web using a non-impact printer, such as an ink jet printer. The composition is applied, in one embodiment, as droplets that remain as discrete shapes on the substrate. In this manner, treated areas and untreated areas are formed on the web. Through this process, the water absorption and control properties of the web can be adjusted as desired while simultaneously treating the web with a composition that improves the physical and/or chemical properties of the web.
Claims29
A tissue product comprising:
- a base sheet comprising pulp fibers, the base sheet including a first side and a second and opposite side,
- a topical composition applied to at least one side of the base sheet,
- the composition comprising a chemical additive, the composition being applied to the sheet in the form of discrete droplets, the droplets having a diameter of less than about 3 millimeters, at least 75% of the composition by weight being located at substantially the surface of the sheet.
A tissue product comprising:
- a base sheet comprising pulp fibers, the base sheet including a first side and a second and opposite side,
- two or more distinct topical compositions applied to at least one side of the base sheet, the compositions comprising chemical additives, the compositions being applied to the sheet in the form of discrete droplets, the droplets having a diameter of less than about 3 millimeters and wherein the compositions are located in discrete substantially non-overlapping regions of the sheet.
