Woven throughdrying fabric having highlighted design elements
View Patent ↗Textured non-woven webs, papermaking fabrics and tissue sheets made using the textured papermaking fabrics can contain design elements set in highlight areas which make the design elements more visible.
1. A woven throughdrying papermaking fabric having a three-dimensional weave pattern which exhibits a texture defined by z-directional elevational differences of about 0.2 millimeter or greater, said fabric containing design elements surrounded by highlight areas, said highlight areas being surrounded by the three-dimensional weave pattern of the fabric and having a texture that is less than the texture of the weave pattern, wherein the weave pattern provides a textured background surface which is the overall predominant sheet-contacting surface of the fabric.
2. The papermaking fabric of claim 1 wherein the highlight area is air-permeable.
3. The papermaking fabric of claim 1 wherein the surface plane of the highlight area is higher than the surface plane of the textured background surface.
4. The papermaking fabric of claim 1 wherein the design element is raised above the surface plane of the highlight area.
5. The papermaking fabric of claim 1 wherein the design element is depressed below the surface plane of the highlight area.
6. The papermaking fabric of claim 1 wherein the design element is air-permeable.
7. The papermaking fabric of claim 1 wherein the design element is higher than the surface plane of the textured background surface.
8. The papermaking fabric of claim 1 wherein the design element comprises an extruded material on top of the highlight area.
9. The papermaking fabric of claim 1 wherein the highlight areas are flat.
10. The papermaking fabric of claim 1 wherein the textured background surface contains substantially machine direction ridges and valleys and the highlight areas are flat.
11. The papermaking fabric of claim 1 wherein the textured background surface contains substantially machine direction ridges and valleys, the highlight areas are flat and the design elements comprise an extruded material on top of the highlight areas.
