Claims
- 1. A method of forming a paper web comprising:
- (a) providing a fibrous web having a first and a second outer surface, said fibrous web containing from about 5 to about 30 weight percent long fibers having an average length of from about 5 to about 10 millimeters and from about 70 to about 95 weight percent short fibers having an average length from about 1 to about 3 millimeters;
- (b) creping the first outer surface of the web;
- (c) printing a bonding material onto the second outer surface of the web such that the bonding material penetrates the web between 10 and 60 percent of the thickness of the web;
- (d) printing a bonding material onto the first outer surface of the web such that the bonding material penetrates the web between 10 and 60 percent of the thickness of the web; and
- (e) recreping the first outer surface of the web, whereby the long fibers are substantially oriented in the z-direction of the web and wherein the Z-peel is increased relative to that of a comparable recreped web made with 100 percent long fibers.
- 2. A method of forming a paper web comprising:
- (a) providing a fibrous web having a first outer surface and a second outer surface, said fibrous web containing from about 5 to about 30 weight percent long fibers having an average length of from about 5 to about 10 millimeters and from about 70 to about 95 weight percent short fibers having an average length from about 1 to about 3 millimeters;
- (b) creping the first outer surface of the web;
- (c) printing a bonding material onto the first outer surface of the web such that the bonding material penetrates the web between 10 and 60 percent of the thickness of the web;
- (d) recreping the first outer surface of the web;
- (e) printing a bonding material onto the second outer surface of the web such that the bonding material penetrates the web between 10 and 60 percent of the thickness of the web; and
- (f) creping the second outer surface of the web, whereby the long fibers are substantially oriented in the z-direction of the web and wherein the Z-peel is increased relative to that of a comparable recreped web made with 100 percent long fibers.
- 3. The method of claim 1 or 2 wherein the creping steps performed after bonding material has been printed onto a surface of the web are performed on the surface of a Yankee dryer while under a high temperature hood in which the temperature of the air within the hood is substantially higher than the temperature of the surface of the dryer.
- 4. The method of claim 1 or 2 wherein the long fibers are redwood or cedar fibers.
- 5. The method of claim 1 or 2 wherein the long fibers are synthetic fibers.
- 6. The method of claim 1 or 2 wherein the short fibers include CTMP fibers.
- 7. The method of claim 1 or 2 wherein the bonding material is applied in a connected mesh pattern.
- 8. The method of claim 1 or 2 wherein the bonding material is applied in an unconnected discrete area pattern, wherein the discrete areas are spaced apart from each other by a distance less than the average fiber length of the web.
- 9. The method of claim 1 or 2 wherein the fibrous web has a homogeneous structure.
