Claims
- 1. A method of making a tissue product comprising:
- (a) forming a non-layered wet web of cellulosic fibers having a selected basis weight from an aqueous stock slurry comprising secondary fibers;
- (b) partially dewatering said web to remove a portion of the water therein, such that interfiber adhesion is enhanced within said web;
- (c) conveying said web to a first drying cylinder and affixing said web to said cylinder such that further interfiber adhesion is effected upon further dewatering to a fiber consistency of at least 90%;
- (d) creping said web from the first drying cylinder with a doctor blade, such that said interfiber adhesion is disrupted;
- (e) conveying said web to a second drying cylinder and affixing said web thereto at the location of a nip formed between the second cylinder and an imprinting fabric having a pattern of raised knuckle areas thereon;
- (f) differentially compressing the web to the second cylinder with said imprinting fabric, said compression resulting in adhesion of said web to said cylinder being greatest in discrete points corresponding to the knuckles of said imprinting fabric;
- (g) differentially creping the same side of said web from the second cylinder; and
- (h) converting said web into a one-ply or two-ply facial tissue or bath tissue product.
- 2. The method as recited in claim 1 further comprising adhering the web to the first cylinder at a pressure nip, said pressure nip being formed by a pressure roll.
- 3. The method as recited in claim 2 further comprising providing the pressure nip with a pressure of about 300-500 pli.
- 4. The method as recited in claim 2 further comprising providing the pressure nip with a pressure of about 100-300 pli.
- 5. The method as recited in claim 1, further comprising imprinting said web with an imprinting fabric having a mesh size of from 20 meshes/in.sup.2 to 200 meshes/in.sup.2.
- 6. The method as recited in claim 1, further comprising imprinting said web with an imprinting fabric having a mesh size of from 50 meshes/in.sup.2 to 100 meshes/in.sup.2.
- 7. The method as recited in claim 1, further comprising adhering the web to the second cylinder at a second pressure nip, said pressure nip being formed by an imprinting fabric wrapped around a pressure roll and a portion of the second cylinder.
- 8. The method as recited in claim 7, further comprising providing said second pressure nip with a pressure from about 50 pli to 300 pli.
- 9. The method as recited in claim 8, further comprising providing said pressure nip with a pressure of about 100-200 pli.
- 10. The method as recited in claim 1, further comprising partially wrapping said impression fabric around said second cylinder without the use of a pressure roll.
- 11. The method as recited in claim 1, further comprising creping said web from the second cylinder when said web has been dried to a consistency of at least 90%.
- 12. The method as recited in claim 1, further comprising adhering said web to the second cylinder by applying adhesive to at least one of said cylinder and web prior to adhesion of said web to the second cylinder.
- 13. The method as recited in claim 12, further comprising applying said adhesive by spraying.
- 14. The method as recited in claim 12, further comprising applying said adhesive by use of a rotogravure roll.
- 15. The method as recited in claim 12 wherein the adhesive is at least one of polyvinyl acetate and polyvinyl alcohol.
- 16. The method as recited in claim 15 wherein said adhesive is less than 1% active adhesive agent.
- 17. The method as recited in claim 16 wherein said adhesive is between 0.2 and 0.6% active adhesive agent.
- 18. The method as recited in claim 15 wherein the adhesive is at a concentration of 0.2-1%.
- 19. The method as recited in claim 15 wherein the adhesive is at a concentration of 0.4-5%.
- 20. The method as recited in claim 1, further comprising providing said first drying cylinder as a steam heated Yankee dryer, said web being thermally dried by adhesion to said dryer.
- 21. A tissue product comprising at least one non-layered recreped ply containing secondary fiber.
- 22. The tissue product of claim 21 wherein the amount of secondary fiber is from about 40 to about 60 weight percent of the total fiber content.
- 23. The tissue product of claim 21 wherein the amount of secondary fiber is from about 25 to 100 weight percent of the total fiber content.
- 24. The tissue product of claim 21 consisting of a single ply.
- 25. The tissue product of claim 21 consisting of two plies, wherein both plies are non-layered recreped plies.
