Embodiment approach

[0084] The embodiments described below are not limiting but illustrative. It will be apparent to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the present invention.

[0085] In one embodiment of the invention shown in FIG. 1 , the first fibrous layer 10 comprises an antiviral composition 22 .

[0086] In a second embodiment of the invention shown in FIG. 2 , the first fibrous layer 10 comprises an antiviral composition 22 . The second fiber layer 12 is combined with the first fiber layer 10 in a face-to-face manner.

[0087] exist image 3 In the third embodiment of the invention shown, a first fibrous layer 10 is joined to a second fibrous layer 12 and a third fibrous layer 13 in a face-to-face manner. Each of these three layers contains an antiviral composition 22 .

[0094] Examples of methods for preparing antiviral compositions:

[0095]Add approximately 2168 grams of water to the mixing tank. The water was heated to 150°F and stirred with the following mixer: LIGHTNIN Mixer, Model No. TF2910, available from General Signal of Tulsa, Oklahoma. About 360 grams of powdered hydroxypropyl cellulose (i.e. film-forming water-soluble carrier, KLUCEL® LFF sold by Hercules Incorporated of Wilmington, Delaware) was added to the water and stirred until a smooth solution was formed (i.e. no lumps) Piece). The solution was cooled to room temperature.

[0096] About 360 grams of nonionic surfactant (ie, polyoxypropylene (5) polyoxyethylene (20) cetyl ether, PROCETYL AWS sold by Croda Incorporated of Parsippany, New Jersey) was added to the cooled solution. The solution was then stirred.

[0097] Stirring was continued while approximately 1080 grams of antiviral agent (ie, salicylic acid commercially available from Rhone-Poulenc SA of Cranbury, New ...

Abstract

A tissue product having an antiviral composition. The antiviral composition includes a film-forming water soluble carrier(s) and one or more antiviral agents. Optional ingredients such as surfactants, thickening agents, dyes, and scents may also be included. The tissue product may include an optional moisture barrier. The moisture barrier may be treated with the antiviral composition. A process for making the tissue product is also disclosed.

Description

technical field [0001] The present invention relates to tissue paper products comprising a water soluble film used as a carrier for an antiviral composition and to a method of making the same. Background of the invention [0002] Whether it is a home, factory, educational facility or any other place where people tend to congregate, preventing the spread of germs is a difficult but always desired task. For example, many lost hours of productive work have been documented as a result of individuals becoming infected with the common cold or influenza virus. [0003] When someone has a common cold or flu virus, the person's mucus is the source of extremely high concentrations of the virus. After the mucus is deposited on the tissue, the virus in the mucus may infect other individuals in contact with it. Transmission of this mucus on tissue paper to other individuals may occur through accidental or inadvertent contact. [0004] As a possible transmission s...
