Method of making tissue sheets with textured woven fabrics having highlighted design elements

a technology of woven fabrics and tissue sheets, applied in the field of drying tissue sheets, can solve the problems that the texture imparted to the dried tissue sheets can detract from the visibility of decorative elements, and achieve the effects of reducing nesting, increasing the bulk of multi-ply tissue products, and enhancing the roll bulk of tissue products

Benefits of technology

[0003] It has now been discovered that tissue sheets can be made by using a woven papermaking fabric, such as an air-laid forming fabric or throughdrying fabric, having a three-dimensional topography with “highlight areas” that surround or otherwise outline “design elements”. The highlight areas ar

example 1

[0030] In order to further illustrate the method of this invention, a papermaking fabric was produced comprising a woven textured background sheet-contacting surface and a woven highlight area which had substantially less texture than the background texture. The fabric was woven using thermally stable polyester, allowing the fabric to be used as a throughdrying fabric. The fabric is substantially the same as that shown in FIG. 1. An RTV silicone (Ultra Black by Permatex, Inc., Solon, Ohio) was applied via extrusion within the highlight area on one side of the fabric. The silicone was applied to form a design element raised above the surface plane of the highlight area, as shown in FIG. 3.

[0031] Tissue handsheet blanks, subsequently used in order to simulate papermaking using the above-described fabric, were made using a process similar to that disclosed in U.S. Pat. No. 5,672,248 to Wendt et al., which is hereby incorporated by reference. In particular, a fiber furnish comprising 1...

[0034] In order to further illustrate the method of this invention, a papermaking fabric was produced comprising a woven textured background sheet-contacting surface and a woven highlight area which had substantially less texture than the background texture. The fabric was woven using thermally stable polyester, allowing the fabric to be used as a throughdrying fabric. The fabric is substantially the same as that shown in FIG. 1. A one component, polyurethane foam (Great Stuff manufactured by Dow Chemical, Inc., of Midland, Mich.) was applied to the highlight area of the fabric. After curing, excess foam was removed to a level substantially the same as the surface plane of the woven textured background sheet-contacting surface, creating a filled highlight area. A design element in the shape of a heart was then sculpted into this filled highlight area by removing selected areas of foam using a high-speed rotary tool (Dremel hand tool with attached cutter bit #125 by Robert Bosch Tool...

Abstract

A method of making tissue sheets is disclosed in which three-dimensional woven papermaking fabrics, such as throughdrying fabrics, are provided with woven highlight areas, particularly woven highlight areas containing design elements which make the design elements more visible in the resulting tissue product.

Description

BACKGROUND OF THE INVENTION [0001] Throughdrying is a well known method of drying tissue sheets, such as those useful for facial tissue, bath tissue, paper towels and the like. In general, the method involves supporting a wet web on a throughdrying fabric and passing hot air through the web / fabric structure to dry the web with minimal compaction. Throughdrying fabrics have evolved into more three-dimensional structures in order to provide texture and bulk to the tissue sheet, which is often perceived as advantageous by consumers. Examples of such relatively three-dimensional throughdrying fabrics are disclosed, for example, in U.S. Pat. No. 5,429,686 to Chiu et al., U.S. Pat. No. 5,672,248 to Wendt et al., and U.S. Pat. No. 6,398,910 B1to Burazin et al., all of which are hereby incorporated by reference. [0002] Although such three-dimensional throughdrying fabrics have many advantages, the texture imparted to the dried tissue sheet can detract from the visibility of any decorative e...
