FIBROUS SUBSTRATE WITH A SOLID HYPOHALITE PRECIPITATE FORMED THEREIN AND PROCESS OF MAKING
First Claim
1. A process for making a hypochlorite-releasing substrate comprising the steps of:
- a. providing at least one layer of fibrous material comprising synthetic fibers;
b. treating the fibrous layer to an effective amount of an aqueous alkaline earth salt solution,c. treating the fibrous layer with an effective amount of a hypochlorite solution, andd. allowing the aqueous alkaline earth salt solution combine with the hypochlorite solution to form a solid hypochlorite precipitate around the fibers in the fibrous material and a liquid phase, ande. removing at least 65% of the liquid phase from the substrate.

Abstract
A cleaning substrate which comprises at least one layer of a solid hypohalite precipitate, wherein the hypohalite precipitate is formed in situ on the layer of substrate material. A process for making a fibrous cleaning substrate comprising the steps of: a) providing at least one layer of fibrous material; b) exposing the fibrous layer to an aqueous alkaline earth salt solution; c) treating the fibrous layer with a hypochlorite solution; d) allowing the aqueous alkaline earth salt solution combine with the hypochlorite solution to form a solid hypochlorite precipitate around the fibers in the fibrous material and a liquid phase, and e) removing at least 65% of the liquid phase from the fibrous substrate.
