Abstract
A method of wetting a web of material is described, which in general provides for applying a wetting solution to the web, and passing the web of material between a set of press rolls. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.
Claims28
A method of wetting a web, comprising:
- providing a hydrophobic web of material comprising a water-dispersible binder;
- applying a wetting solution to the web;
- and
- passing the web between a pair of press rolls.

A method of wetting a web, comprising:
- providing a web of material from a source;
- controlling the draw of the web from the source;
- perforating the web;
- positioning the perforated web between a pair of press rolls;
- and
- applying a wetting solution to the web with an add-on greater than about 25% to yield a wet web;
- wherein the wet web retains a solution add-on greater than about 25%.
4 more elements
An apparatus for wetting a substrate, comprising:
- a pair of press rolls;
- and
- a solution applicator which delivers a wetting solution to a hydrophobic web comprising a water-dispersible binder;
- wherein the web passing between the press rolls can absorb the solution with an add-on of at least about 25%.
